Abstract
The 2008 Global Financial Crisis fueled a steep decline in the U.S. luxury goods
market. According to Euromonitor, retail sales fell from a record $62.8 to $52.5 billion
over 2007-2009. Interestingly, the Lipstick Effect suggests that small, affordable
luxury goods fare better during an economic downturn since consumers seek to maintain
wellbeing and enhance attractiveness. The study employs a subset of the Kilts-Nielsen
Consumer Panel Dataset (KNCPD) for the period 2004-2011, data on households that
consume a particular good of affordable luxury, fragrances. Evidence reveals that
perfumes do not adhere to the lipstick effect during the recession, perhaps because
fragrances are purchased as gifts more frequently than most beauty products. The study
further shows how households alter buying behavior among perfume qualities. Findings
imply that during the crisis, households substitute towards premium and private-label
fragrances and away from mass-market perfumes. Compared to wealthy households,
those of low-income exhibit relatively higher price sensitivity, lower opportunity cost of
time, and greater shopping effort. Low-income households benefit more from price
reductions on premium goods. The recession-induced, heightened preference for
affordable, private-label fragrances explains the latter shift in purchasing patterns.

I. Introduction
i. Background
Following the 2008 Global Financial Crisis, the luxury goods sector has recovered
swiftly. Reuters (2013) reports that sales rapidly returned to pre-crisis levels by 2012, and
global leading luxury conglomerates Louis-Vuitton-Mot-Hennessy (LVMH) and
Pinault-Printemps-Redoute (PPR), re-named Kering, experienced higher sales growth in
the U.S. than in China. In 2015, consumers in the United States alone, boosted by a
strong dollar, shelled out a total of $79.3 billion on luxury goods, outperforming those in
Japan, Italy, France, and China combined (see Bain & Company 2015; Euromonitor
2016). Wealthy households clearly have deep pockets when it comes to spending on
luxury goods. Leading market research firm Euromonitor International (2016) reports
that despite faltering growth in U.S. sales of luxury goods to foreigners, largely due to
currency appreciation, heightened domestic demand drives luxury expenditures.
Improved economic conditions, as seen by the increased availability of employment and
the rise in wages, prompt forecasts of strong growth in sales of luxury goods.
The largely positive outlook is but a recent phenomenon. The Global Financial
Crisis of 2008 may have subsided, yet not without leaving significant destruction in its
immediate aftermath. The recent downturn did not discriminate in its impact, bringing
hardship to businesses and consumers across most sectors and socio-economic
backgrounds. In particular, much debate continues to surround the effect of the Great
Recession on the luxury goods market. Prior to the crisis, the luxury goods and services
sector was characterized by high margins and strong growth. Sales of luxury goods
collapsed, as the U.S. experienced a steep decline in luxury retail revenues from a record
2
$62.8 to $52.5 billion over the period 2007-2009 (Euromonitor 2016). Euromonitor
(2016) divides the luxury goods sector into eight strategic business units: Designer
Apparel and Footwear, Wines and Spirits, Accessories, Electronic Gadgets, Jewelry and
Timepieces, Leather Goods, Paper Goods, and Super Premium and Personal Care.
Despite the overall decline in luxury spending, evidence suggests that certain sub-
categories within luxury actually fared better than others during the recent recession.
Before exploring idiosyncrasies driving luxury goods expenditures, it is important
to briefly acknowledge the paradox characterizing luxury purchases. In her 2001
interview with Chairman and CEO of LVMH, Bernard Arnault, Suzy Wetlaufer, the
former editor of the Harvard Business Review, introduces the idea responsible for the
success of Arnault and LVMH. She asserts that, no one needs [luxury items], of course,
yet millions desire them (Wetlaufer 2001). These products have little utilitarian purpose,
serving only to achieve dreams or selfish desires, as perceived by consumers (Wetlaufer
2001). Luxury spending is largely driven by the brands power, prestige, and ability to
portray a particular aura that elicits an emotional response.
Consumption of luxury goods is characterized by desire, rather than need. The
challenge with desire is that it exhibits volatility, either falling prey to harsh economic
conditions or preying on selfish motives of the individual to maintain or increase
wellbeing, in other words, to treat themselves (Biciunaite 2013). Economists
acknowledge that recessions are associated with heightened spending on both inferior
goods, those that increase in demand when income declines, and goods or services that
boost morale. The whole luxury industry is propelled by womens desire to spoil
themselves, and the sales of small, affordable luxury goods often benefit the most from
3
this desire. Leonard Lauder, Chairman Emeritus of Este Lauder, coined the term,
Lipstick Effect, or the principle that sales of beauty products are inversely correlated
with the health of the economy (see Biciunaite 2013; Schaefer 2008). Although evidence
conveys that lipstick retail sales did not actually withstand the recent recession, other
small luxury products, including nail polish, did fare well (see Allison and Martinez
2010; Biciunaite 2013). From a psychological standpoint, Hill et al. (2012) maintain that
during an economic downturn, spending on most beauty products remains fairly stable, or
increases, as women engage in cheap indulgences to enhance attractiveness and promote
male desirability. From an economic perspective, Gao, Kim, and Zhang (2013) show that
consumers re-allocate resources towards leisure spending (e.g., spending on
entertainment) to maintain wellbeing. Research strongly suggests that affordable, luxury
goods perform well during an economic downturn.
ii. Research Questions
This study examines buyer behavior in the periods prior to and during the Great
Recession, with respect to one luxury good, womens fragrances. Motivations for
choosing perfumes are multifold. Like cosmetics, womens fragrances exist under the
Euromonitor (2016) luxury category of Super Premium and Personal Care and are
characterized as small, affordable luxuries without clear generic, or store brand,
alternatives. For example, fragrances differ from pharmaceutical drugs, as none bear the
name of a local drugstore (Bronnenberg et al. 2015). Even affordable perfumes have a
brand label. Motivations for examining consumption patterns with respect to perfumes
stem from the unique position of fragrances within the luxury sector.
4
During recessions, individuals seek to decrease spending and often do so by
consuming more affordable, yet generally lower quality, alternatives of expensive goods.
(see Jaimovich, Rebelo, and Wong 2015; Nevo and Wong 2015). The consumer
purchases three fragrance types, each associated with different levels of price and quality.
According to Euromonitor (2015), premium fragrances are characterized by high price
and quality (e.g., Chanel, Gucci, Yves Saint Laurent), and mass-market fragrances (e.g.,
Avon, Stetson, The Body Shop) are more affordable, of lower quality, and rarely carry a
Designer label. Of the three types, private-label is the cheapest, and demand for private-
label rises during recessions (Dub, Hitsch, and Rossi 2015). Nonetheless, buying a
private-label fragrance is still considered a luxury transaction.
Given the aforementioned attributes, the purpose of this study is to examine the
performance of fragrances during the recent recession. Euromonitor (2015) reports that
U.S. fragrance retail sales decrease from approximately $7.5 to $6.5 billion over 2007-
2009, and this study uses a particular dataset of household perfume transactions to either
confirm or refute fragrance adherence to the lipstick effect. Secondly, this paper provides
further insight on how certain household demographics, notably annual income, influence
fragrance expenditures throughout the crisis. Exactly how household income determines
shifts in consumption behavior, with respect to various qualities of one luxury good,
remains largely unexplored. Substituting towards more affordable fragrance alternatives,
reducing the quantity purchased, or delaying transactions to a later date, represent a sub-
sample of the various means by which household members adjust to business cycle
fluctuations. Results reveal differences between the magnitude of shifts in shopping
behavior for wealthy households and those of lower socio-economic standing.
5
Based on the motivations presented, the research questions, with respect to the
years of the Great Recession, are as follows:
(1) Do fragrance expenditures adhere to the lipstick effect?
(2) Do households substitute among the three qualities of fragrances? If so, how
does income affect household substitution behavior?
iii. Narrative
Findings suggest that during the recession, womens fragrances do not, in fact,
follow the positive trend implied by the lipstick effect. A possible explanation for the
deviation is that fragrances are purchased as gifts more frequently than most beauty
products. The study then goes on to illustrate how households alter buying behavior by
substituting within luxury, among three types of fragrances. Graphical analyses and
corresponding regression results imply that during the recession, households of low- and
high-income substitute towards premium and private-label fragrances and away from
mass-market perfumes. A possible reason for this puzzle is that households benefit from
crisis-driven price reductions on premium fragrances (see BCG 2010; Nevo and Wong
2015). A heightened preference for affordable, private-label fragrances explains the latter
shift in consumption (Dub, Hitsch, and Rossi 2015). Findings support conclusions of
Hammerbeck (2008) and Quelch and Harding (1996) that private-label spending and
market share increase during the crisis and decline under strong economic conditions.
Despite the overall drop in fragrance expenditures during the recession,
interestingly, both wealthy and low-income households experience relative increases in
6
their average shares of premium fragrance expenditures.1 Recession-driven income
shocks, and changes in employment status, trigger declines in household opportunity cost
of time (Nevo and Wong 2015). Kaplan and Menzio (2015) support that households of
unemployed shoppers spend less on the same goods than do households of employed
shoppers. Griffith, OConnell, and Smith (2015) and Nevo and Wong (2015) assert that a
recession-induced lower opportunity cost of time influences households to re-allocate
time towards shopping effort to lower spending (e.g., searching for special deals by using
coupons, frequenting discount stores, or purchasing on sale).
Compared to low-income households, wealthy households exhibit a greater
opportunity cost of time and allocate less effort to searching for discounts when shopping
(Griffith et al. 2009). BCG (2010) conveys that retailers slash prices of premium goods
during recessions. Low-income households, compared to those of high-income, exhibit
larger increases in their average share of premium fragrance expenditures. Increases in
shopping effort amount to realized benefits from deals on premium fragrances (Nevo and
Wong 2015). The behavioral change by price sensitive, low-income households leads to a
significant increase in their average share of premium fragrance expenditures.
In turn, substitution towards premium perfumes dampens spending on mass-
market fragrances. Low-income households benefit from discounts on premium
fragrances and significantly decrease mass-market fragrance consumption. Wealthy
households follow a similar pattern, yet to a lesser extent. The higher opportunity cost of
time of high-income households also explains the relatively larger increase in their
average share of private-label fragrance expenditures, as compared to that of low-income
1 The Average Share of Premium Fragrance Expenditures is the average of the share of premium fragrance expenditures, divided by the total fragrance expenditures in U.S. dollars, for U.S. households within a given year.

7
households. The wealthy perceive increasing private-label expenditures as a more time
efficient means, compared to increasing shopping effort, for lowering expenditures. The
narrative implies that opportunity cost of time and income specific buying behavior act as
drivers of recession-induced substitution among the three types of fragrances.
iv. Structure
The remainder of the paper proceeds as follows: Section II outlines consumption
theory that sets the stage for the discussion of prior empirical research on shopping
behavior during an economic downturn. Section III describes The Nielsen Consumer
Panel Dataset (KNCPD), provided by the Kilts Center for Marketing at the Chicago
Booth School of Business, presents descriptive statistics of household demographics, and
conveys methods of fragrance quality differentiation. Section IV introduces the
regression models and defines key variables. Section V reports the graphical and
regression results of the benchmark model, offers potential explanations for findings, and
discusses results from robustness checks and extensions. Finally, Section VI and Section
VII present outcome implications for both the luxury consumers and the luxury
corporations, as well as some concluding thoughts and future research suggestions.

II. Literature Review
i. Overview of Consumption Theory
The contribution of this study is to determine the impact of the Great Recession
on household buying behavior, with respect to an affordable, luxury good. Recent
empirical work focuses on the shifts in buying behavior for decreasing spending during
an economic downturn. Several other theoretical and empirical studies hypothesize as to
motivations driving luxury good expenditures and measure willingness to pay for a
brand. Before presenting related empirical work, this section provides an overview of
consumption theory to establish the framework for the discussion to follow.
Nobel Laureate and Princeton University professor, Angus Deaton (1992)
evaluates the Permanent Income Hypothesis, developed in 1957 by Milton Friedman,
which examines the propensity of the individual to smooth consumption over time. In
anticipation of an economic bust that triggers negative shocks to income, consumers
prioritize saving over spending. Before an economic boom, households generally borrow,
rather than save. The Deaton Paradox (1992) implies that large shocks to income are not
followed by consumption shocks of similar magnitude. Deaton resolves the contradiction
by explaining that individual income is more variable than that of the aggregate economy.
A certain individuals income may increase, while the income of another falls. Only after
acknowledging how individual consumption fluctuates with respect to income, do
economists reconcile aggregate patterns with those at the individual level.
Should consumers anticipate and discount future shocks to income, consumption
may not, in fact, be as smooth as Friedmans Permanent Income Hypothesis suggests.
The Deaton (1992) framework of individual consumption behavior establishes a basis for
9
analysis of how individual purchasing patterns fluctuate during an economic downturn.
Although theoretical in nature, when applied to the Great Recession, findings predict that
consumption falls in the periods shortly before and during the crisis. This study will
utilize the theoretical basis to analyze consumption behavior of U.S. household panelists
from various socio-economic backgrounds, with respect to a particular luxury good.
ii. Discussion of Related Empirical Research
More recently, Aguiar and Bils (2015) employ the Deaton (1992) framework to
examine individual purchasing behavior during the Great Recession. Changes in
consumption inequality are determined by analyzing expenditure trends of high- and low-
income households. Using the Consumer Expenditure Surveys Interview Study (CE) and
a demand system test, Aguiar and Bils (2015) first explore patterns in after-tax income
inequality, which rises by 33 percent over 1980-2007. Consumption inequality increases
by 11 percent over the same time period. The study focuses on how consumption
inequality moves in response to income shocks. Luxury is defined as non-durable
entertainment, and grocery goods are considered necessities. On average, high-income
households shift consumption towards luxury goods and away from necessities more than
low-income households do. Evidence suggests that high-income households shift
expenditures away from food, towards entertainment, over 2008-2010, while low-income
households shift spending away from entertainment, towards food, over the same period.
Total expenditure inequality rises. Aguiar and Bils (2015) then prove that consumption
inequality, defined as the high-income households greater propensity to consume
luxuries, instead of necessities, mirrors income inequality more than total expenditure
10
patterns imply. Like Aguiar and Bils (2015), this study will narrowly focus on recession-
induced expenditure shifts by high- and low-income households.
Several empirical studies analyze the effects of the Great Recession on
consumption patterns. Gao, Kim, and Zhang (2013) focus on the consumption of leisure
goods, specifically nondurable entertainment. Consumer Expenditure Survey (CES) data
for select years within the 2003-2010 period and the Probit model are used to examine
the impact of changes in income on the likelihood of making an entertainment purchase.
While the recession exerts a statistically significant negative effect on income, leisure
spending does not decline substantially. Gao, Kim, and Zhang (2013) explain the puzzle
by suggesting that rational consumers, wrought with financial hardship, re-allocate
resources to maintain wellbeing. From a consumer psychology standpoint, a study by Hill
et al. (2012) supports the lipstick effect and suggests that recessions trigger increases in
spending on beauty products driven by womens need to enhance attractiveness.
Consumption of small, luxury goods may, in fact, increase during economic downturns.
Dub, Hitsch, and Rossi (2015), Jaimovich, Rebelo, and Wong (2015), and Nevo
and Wong (2015) find that consumers experience shifts in shopping behavior during the
Great Recession. Jaimovich, Rebelo, and Wong (2015) introduce the concept of trading
down, and show that consumers are more likely to purchase low quality goods and
services during an economic downturn. Although documented as having ended in June
2009, the study acknowledges that the recession continued to negatively affect average
and median household income until 2012. Consistent with the aforementioned, this study
will define the Great Recession years as 2008-2011. Jaimovich, Rebelo, and Wong
(2015) determine the quality of the good by the individuals willingness to pay for it.
11
Price is used as a proxy for quality, as consumers generally associate high price with high
quality. This study operates under the same assumption. The total price paid, and
corresponding price measures, are obtained from Yelp!, and The U.S. Census of Retail
Trade provides information on firm employment and sales for insight on labor intensity
and market share. Price data from Yelp! are merged with Compustat data containing
information on employees, sales, operating expenses, and cost of goods sold. The study
reveals that expenditures at low quality restaurants, those offering limited service, fall by
4.7 percent, while expenditures at restaurants of high quality, those offering full service,
fall by 10.2 percent, thus confirming the trading down hypothesis. Trading down
behavior is then related to employment, as substitution towards goods of lower quality
accounts for one-third of the heightened unemployment during the Great Recession.
Further supporting the narrative of trading down, Dub, Hitsch, and Rossi (2015)
utilize the Nielsen Homescan Dataset, with information on shopping trips, and find a
negative causal effect of income on private-label expenditures. Furthermore, estimates
show a positive trend in private-label shares in the period prior to the Great Recession.
Quelch and Harding (1996) imply that growth in private-label expenditures increases in
times of economic hardship. Evidence of strong demand for private-label during an
economic downturn supports conclusions of Jaimovich, Rebelo, and Wong (2015).
Nevo and Wong (2015) examine recession-induced household substitution
behavior between goods and time. Similar to Dub, Hitsch, and Rossi (2015), the study
uses the Nielsen Homescan Dataset to test the propensity of the household to buy items
on sale or in bulk, purchase generic goods, increase coupon usage, and shop at more
affordable retail stores. A crisis-driven negative income shock triggers a decline in
12
household opportunity cost of time. Consumers re-allocate time towards shopping for
household goods and services, with the aim of achieving lower expenditures. Griffith,
OConnell, and Smith (2015) confirm the aforementioned by using Kantar Worldpanel
data on British households over 2005-2012 to show that households increase shopping
effort to lower the average per calorie price of the grocery basket. Shopping activities, as
a share of total expenditures, increase during the recession.
Griffith, Leibtag, Leicester, and Nevo (2009) analyze similar shopping behavior,
emphasizing the effect of consumer demographics on activities such as purchasing on
sale, buying larger quantities, shopping at discount stores, or purchasing the generic
version of a good. Household savings are conditional on demographics, which include
household income, composition, and size, as well as the age and the employment status
of household members. Employing data from the TNS Worldpanel, containing
information on 25,000 households across Great Britain, Griffith et al. (2009) show that
households shopping by car purchase about 2 percentage points more food on sale than
those shopping by foot, by public transportation, or less frequently by car. High-income
households exhibit low marginal utility of income and high opportunity cost of time; they
generally do not allocate as much time towards seeking out deals, and purchasing on sale,
as do their low-income counterparts. Similarly, households of retirees, childless couples,
and single adults save less than do households of families. Griffith et al. (2009) conclude
by exploring preliminary findings of a study of U.S. households and convey the
importance of geography and household demographics on purchasing habits and realized
savings. Similarly, this study will focus on the household demographic of income and its
effect on substitution among three types of womens fragrances.
13
Krueger and Mueller (2010) offer further support for the impact of demographics
on shopping behavior with the aim of lowering expenditures. Unemployment spiked
during the recession, peaking at 10 percent in October 2009 (Bureau of Labor Statistics
2012). Krueger and Mueller (2010) find that unemployed people, compared to the
employed, allocate more time towards shopping, which presumably includes activities
cited by Griffith et al. (2009) and Nevo and Wong (2015). Using the KNCPD for years
2004-2009, Kaplan and Menzio (2015) assert that households with fewer employed heads
spend less on the same goods, on average, than do households in which all heads are
employed. The formers ability to lower expenditures is attributed to shopping at more
stores. Differences in shopping behavior between employed and unemployed, and high-
and low-income, household members, set the stage for the narrative of this study.
Finally, Civi (2013) supports that growth opportunities exist for companies that
identify changing consumption patterns in anticipation of and during a recession, and in
doing so, adapt strategies to match shifts in buyer behavior. Companies may find that
recent crisis-induced shifts in purchasing patterns and overall consumer perception of
luxury, when capitalized upon, provide business growth opportunities.
iii. Motivations for Purchasing Luxury
Given the ability of consumers to shift purchasing habits during the recession, it is
important to first consider the motivations that drive luxury expenditures. Several
theoretical and empirical studies, in conjunction with market research reports, explain
classical and changing incentives behind luxury spending.
In his social critique on the leisure, or wealthy, class, economist Thorstein Veblen
(1902) claims that consuming luxury goods is an effective means for seeking status, a
14
behavior known as the Veblen Effect. Consumers generally exhibit a higher willingness
to pay for a luxury good with cheaper, functionally equivalent alternatives. Veblen argues
that luxury transactions are characterized by conspicuous consumption, purchasing to
advertise affluence and status.2 An individual buys a luxury good to flaunt material
wealth or influence public image. Bagwell and Bernheim (1996) further describe the
source of the Veblen Effects and find that consumers demonstrate a higher willingness
to pay for a luxury good to ensure social acceptance into an exclusive class.
Miller (1975) and Creedy and Slottje (1991) build on Veblen (1902), asserting
that wealthy consumers derive utility from price. The consumer gathers utility not only
from the high quality, but also from the price premium associated with the brand label.
Creedy and Slottje (1991) convey that price increases are believed to raise consumer
utility, which Miller (1975) supports by asserting that luxury goods are purchased for
superficial reasons associated with brand image and status. A review of Simon Fans
Vanity Economics: An Economic Exploration of Sex, Marriage, and Family by Bertocchi
(2015) best encapsulates theoretical conclusions; a fixation with signaling status drives
irrational choices that oppose basic economic assumptions.
Bronnenberg, Dub, Gentzkow, and Shapiro (2015) and Jin, Zilberman, Heiman,
and Li (2011) take an empirical approach to measuring willingness to pay (WTP) for
brands. Jin et al. (2011) use consumer stated preferences for purchasing brands and focus
on factors driving consumption of brand name products over corresponding generic
alternatives. Survey data are gathered from Texas, California, and Israel to determine
variations in brand preferences across both geography and four product categories (e.g.,
2 Miller (1975) and Veblen (1902) are briefly discussed in Section II of Chiaroni, C. (2015). The Impact of the Connecticut Luxury Automobile Tax on Consumption Patterns. Unpublished manuscript, Department of Economics, Princeton University.
15
electronics, clothing, processed food, and fresh produce). Overall WTP for brands in the
four sectors remains the same, regardless of geography. Brand name consumer
electronics products elicit a higher WTP than brand name clothing, processed food, and
fresh produce. Variations in WTP magnitude for brands lead Jin et al. (2011) to conclude
that business strategies should be tailored to the WTP of local consumers.
While Jin et al. (2011) confirm that consumers exhibit higher WTP for brands,
Bronnenberg et al. (2015) convey that individuals may overestimate benefits of a brand
name product with respect to quality. In an empirical study of WTP for National versus
store brands, Bronnenberg et al. (2015) determine the impact of occupation related
knowledge and expertise on purchasing patterns. In a procedurally similar process to
Nevo and Wong (2015), Bronnenberg et al. (2015) use Nielsen Homescan Data from
2004-2011 and a survey revealing consumer demographics (e.g., product knowledge,
schooling, college major, and occupation). Purchases of headache remedies made by
physicians and pharmacists, and food product transactions made by chefs and food
preparers, are recorded. Nielsen Retail Scanner data and Wholesale Price data from
National Promotion Reports PRICE-TRAK are employed to compute product prices and
retail margins. Consumer information largely impacts choices, as informed consumers
purchase store brand, instead of national brand, pharmaceuticals.
The following market research report by The Boston Consulting Group (2010)
raises two important factors, the access to widespread information through electronic
venues, and the long-term impact of the Great Recession on willingness to pay for brand
name, luxury goods, that call into question the validity of aforementioned conclusions.
BCG (2010) supports that luxury holds a mystique extending beyond its clear
16
superiority to the ordinary. Clearly, craftsmanship, service, and image contribute to
the intrigue surrounding a luxury brand (BCG 2010). However, recent devastating
economic and social effects of the Great Recession prompt todays consumer of luxury to
search for further reason to spend. Financial tumult subdues purchasing incentives
characterized by conspicuous consumption (Veblen 1992). Previously, brand image was
more important than quality, as consumers perceived luxury goods in superficial terms
(BCG 2010). The crisis unhinges financial security, inhibits the ability to splurge, and
stigmatizes conspicuous consumption at a time of immense financial hardship.
The Great Recession induces luxury companies, and mass-market competitors, to
alter techniques of pricing, marketing, and branding. Many mass-market companies
imitate premium counterparts in elevating brand status through new marketing initiatives
focused on crafting a premium image for the brand, yet offering it at a mass-market price
(BCG 2010). High-end manufacturers and retailers simultaneously cut prices of luxury
goods to stimulate demand. Consumers perceptions of purchasing luxury change, and
the delineation between premium and mass-market goods becomes blurred as a result of
strategic decisions made by manufacturers and retailers of luxury.
Overall, theoretical research into consumption inequality, income business cycle
variability, and motivations for purchasing luxury, establish a framework for this study.
Luxury consumption may remain stable, or increase, as individuals defend wellbeing or
enhance attractiveness (see Gao, Kim, and Zhang 2013; Hill et al. 2012). On the other
hand, the recession is associated with increases in shopping behaviors such as trading
down, or buying goods of lower quality, buying in bulk or on sale, and heightening
shopping effort in general (see Dub, Hitsch, and Rossi 2015; Jaimovich, Rebelo, and
17
Wong 2015; Nevo and Wong 2015). Much research also exists on the impact of
demographics on shopping behavior (see Griffith et al. 2009; Kaplan and Menzio 2015,
forthcoming). This study examines how the recession affects fragrance expenditures and
how household income impacts crisis-driven substitution among fragrance qualities.
The KNCPD, for years 2004-2011, is utilized. Due to the overall size of the data,
the subset under observation includes only households that engage in fragrance
transactions. Just as Jaimovich, Rebelo, and Wong (2015) employ Yelp! to categorize
restaurants, this study creates a database using Nielsen information on fragrance brands
in conjunction with Euromonitor categorizations of premium and mass-market brands.
Perfumes lack the generic alternative that Griffith et al. (2009) and Nevo and Wong
(2015) cite when referencing shifts in shopping behavior. This study examines trading
down, introduced by Jaimovich, Rebelo, and Wong (2015), or substitution towards more
affordable perfumes. Finally, conclusions from graphical and regression analyses provide
the opportunity to extrapolate implications, much like Civi (2013) and Jin et al. (2011)
do, with respect to trends characterizing luxury good consumption during the recession.

III. Data Description
i. Kilts-Nielsen Consumer Panel Dataset Description
This section introduces the data, The Kilts-Nielsen Consumer Panel Dataset
(KNCPD) provided by the Kilts Center for Marketing at the Chicago Booth School of
Business, and the method of collection. The dataset includes information on grocery,
food, and home supplies purchased by 125,000 household panelists across 61 geographic
areas, 52 major markets and nine Census Divisions, over the time period 2004-2011.3 The
KNCPD contains a longitudinal study of approximately 40,000 households for 2004-
2007, and 60,000 households for 2007 onwards, who convey information to Nielsen on
household demographics, products purchased and corresponding product attributes, as
well as the retailer from which the goods are purchased. To maintain a representative
sample of U.S. household consumption, Nielsen randomly recruits households through
the mail and Internet, offering sweepstakes, monthly prize drawings, and gift points
awarded for weekly data transmission. Nielsen maintains communication with panelists
through issuing monthly newsletters, personalized computerized tips and reminders, and
letters from the President, all to ensure cooperation. Nielsen depends on households to
join the panel and remain committed, since panelists who participate over the long-term
allow for longitudinal analysis of changes in household consumption. When households
become inactive or fail to report transactions as instructed, Nielsen replaces them.
The in-home scanner system, intended for household use, records the store at
which the product was purchased, the date of purchase (e.g., month, day, and year), the
quantity, or number of units, purchased, and the total price paid for the good at the
3 All Section III information regarding the KNCPD is obtained from the KNCPD Manual (2013).

Universal Product Code (UPC) level. Household demographics include, but are not
limited to, household annual income, and the age, education by gender, and occupation
by gender of the heads of the household. Nielsen also reports the presence and age of
children in the household. For each shopping trip, summary information, containing the
trip date, retailer code, store code, store zip code, and total expenditures, is provided.
UPC codes for the ten Nielsen Food and Non-Food Departments are included in the
product files, and these UPC-level data provide the price of the product, the number of
units purchased, and the product attributes, which include the UPC description, Nielsen
brand description, packaging, and size of the product. In these data, the unit of size for
fragrance transactions is not recorded. Households also note whether the purchase was
made using a coupon, as well as the total discount amount from the coupon. Coupon
usage is then taken into account when calculating the final amount spent per good.
The dataset contains approximately 1.5 million individual product UPC codes
present in the consumer panel files. Data referring to household demographics are
updated annually. These data are presented in separate files based on the type of
information provided (e.g., Panelists, Trips, Purchases, Retailers, Products, Product Extra
Attributes, and Brand Variations). The Panelists file includes demographic, geographic,
and product ownership information on the panelists, reported according to Nielsen
specifications. The Trips file offers summary information, such as the retail chain, the
total amount spent during the trip, the retail location of the purchases, and the date of the
trip, for all shopping trips made by each household. The Purchases file presents
information on the products purchased, specifically the quantity of the good purchased
and the total price paid for the good, as well as coupon usage. The Products file presents
20
information for each of the UPC codes in the dataset, providing detail on the UPC
description, Nielsen brand description, and the size in units specific to the product.
This study employs a specific subset of the KNCPD data, only households that
engage in fragrance transactions over the period 2004-2011. Time is divided into two
categories. The period prior to the Great Recession is defined as 2004-2007, and the
period during the crisis is defined as 2008-2011. To construct the dataset, the Panelist,
Trips, Retailers, and Purchases files are merged together by quarter, totaling thirty-two
files for the years 2004-2011. Each year contains four individual files, which report
information from the Panelist, Trips, Retailers, and Purchases files, segmented by quarter.
The Product files are manipulated to contain only information relevant to the good
of interest, womens fragrances. The product group code corresponding to womens
fragrances is identified. Several Nielsen product module descriptions relate to the specific
product group code. For example, childrens cologne and gift sets, womens cologne and
perfume, and womens gift sets and skin care packages, are under the same product group
code. However, only the product module code for womens cologne and perfume (e.g.,
eau de toilette, eau de parfum) is relevant. For the purposes of the study, only product
information specific to perfume transactions is retained. Each of the previously merged
files by quarter is appended by year, 2004-2011. Within the append operation, the
product information specific to womens fragrances is also merged using the variable in
common, UPC code. The UPC codes in the truncated dataset refer only to womens
fragrances. Once the aforementioned is repeated in eight steps, one step for each year, the
complete dataset is created by appending files for the period 2004-2011.

i.i. Descriptive Statistics
i.i.i. Household Panelist Demographics
The subset of the KNCPD includes information on 17,107 U.S. household
panelists, as shown in Table 1. Households are organized into categories based on
income, and household incomes range from $0 to more than $200,000.4 These data
exclude top-earning households, as Nielsen incentives for participation attract only a
subset of the total population below a certain annual income level.
Table 1. Household Income Status Source: Kilts-Nielsen Consumer Panel Dataset (2004-2011).
This study groups household panelists into categories of low-income, those with
an annual salary less than $65,000, and high-income, those with an annual salary greater
than, and including, $65,000. Table 1 shows that low-income and high-income
households account for approximately 70 and 30 percent of sample U.S. households.
4 The KNCPD defines the highest household income category as annual income greater than $200,000. This definition is gathered from the KNCPD Manual (2013).

Table 2 records the employment status of heads of the household and reveals that
the primary consumers of womens fragrances are women themselves. Only 12 percent of
the 17,107 household panelists have a male head. These data include almost as many
household panelists with female heads who are not employed for pay, 3 percent, as those
households with female heads who work fewer than 30 hours per week, 5 percent. About
80 percent of sample households have female heads working at least 30 hours per week.

With respect to education, Table 3 conveys that approximately 54 percent of the
households in the dataset include heads that did not receive a college degree. Households
that contain one head with a college degree constitute 20 percent of the total sample, and

These data include household heads whose ages exist within a very narrow range
(e.g., 29-36), and the mean is 32 years. Table 4 shows that the majority of consumers of
luxury fragrances are women in their late twenties to mid thirties.
Given the household demographic information for the sample of 17,107
households that purchase fragrances within the time period 2004-2011, Table 5 explores
changes over time in the composition of households that report fragrance transactions.

Source: Kilts-Nielsen Consumer Panel Dataset (2004-2011). Notes: The table presents the set of household demographics that are included in the demographic controls of regression Models I-IV (i)-(iii) presented in Section IV. The table shows how the demographic composition, measured in percentages, of the sample household panelists purchasing fragrances changes over time. From the pre-crisis period to the recession, low-income households within the sample decline by approximately 9 percent, while the high-income households in the sample increase by about 8 percent. The remaining demographics remain roughly consistent for both time periods of interest.
The composition check is to confirm that movements in fragrance expenditures,
and movements in household buying behavior with respect to fragrances of various types,
are to be attributed to the negative impact of the recession rather than to the change in the
sample of households over time. Recession-induced negative shocks to income certainly
25
force low-income households to fail to appropriately report expenditures, or to drop out
of the sample altogether, which Table 5 confirms. In the period before the recession,
approximately 74 percent, compared to 65 percent in the crisis period, of the households
in the sample are low-income. Table 5 does not reveal substantial changes over time in
other demographics. Categorical, independent variables in the regression models,
presented in Section IV, control for compositional changes.
i.ii. Methods of Quality Differentiation
Two distinct processes of differentiating among qualities of fragrances are
considered. Quality can be most clearly determined using either of the following
methods: measuring price per ounce or recognizing the quality behind the brand. The first
method involves distinguishing quality (e.g., high quality, medium quality, low quality)
based on the price per ounce of the fragrance purchased. In the second method,
fragrances are categorized as either premium, mass-market, or private-label, based on the
brand. Cross-referencing information provided by the Nielsen Brand Description term,
with Euromonitor categorizations of premium and mass-market brands, facilitates the
procedure.5 The following section begins by explaining the first method, the
categorization of fragrances by quality using price. Graphical analyses explore the
implications associated with using the first method of quality differentiation in charting
low- and high-income households buying behavior. Only after acknowledging important
limitations of the first method, does the study develop the second method of quality
segmentation by brand.
5 The second method of quality differentiation, particularly the process of cross-referencing the KNCPD Brand Description term with Euromonitor International Passport GMID data, will be discussed in detail in Section III.i.ii.iii.
26
i.ii.i. Quality Differentiation By Price
Evaluating fragrance quality requires determining the price per unit, presumably
the price per ounce in U.S. dollars, of the fragrance purchased. The variable Final Price
Paid is generated by subtracting the Coupon Value, or the dollar value of coupons
applied to the fragrance expenditure, from the Total Price Paid, or the total price paid for
all fragrances before discounts are applied to the transaction. Price Per Unit is then
calculated by dividing the Final Price Paid by the Quantity, or the number of units of the
fragrance purchased.6 The distribution of the Price Per Unit for all fragrance transactions
determines the three price ranges that correspond to categories of low, medium, and high
quality perfumes. Fragrances whose Price Per Unit falls in the top third percentile are
grouped into the high quality category, and those whose Price Per Unit falls within the
bottom third percentile are considered low quality. In absolute terms, low quality
fragrances have a Price Per Unit between $0 to $5, inclusive; medium quality fragrances
have a Price Per Unit between $5 to $10, non-inclusive; high quality fragrances have a
Price Per Unit between $10 to $240, inclusive. The unit of measure for Price Per Unit,
with respect to fragrances, is not provided by Nielsen. Constructed using the method of
quality differentiation by price, the following figures support the established narrative of
shifts in high- and low-income household buying behavior throughout the recession.
i.ii.ii Quality Differentiation By Price: Graphical Analysis
Figure 1 reveals the average shares of fragrances of low, medium, and high
qualities consumed over 2004-2011. The Final Price Paid for Low Quality Fragrances,
for each household within a given year, is determined. The Average Share of 6 Definitions of the italicized terms are either obtained from the KNCPD Manual (2013) or calculated using terms defined in the KNCPD Manual (2013).
27
Expenditures on Low Quality Fragrances is calculated by dividing the sum of the Final
Price Paid for Low Quality Fragrances by the Final Price Paid and finally, computing
the average. Similar procedures are repeated to create the Average Share of Expenditures
on Medium Quality Fragrances and the Average Share of Expenditures on High Quality
Fragrances. The Average Shares of Fragrance Expenditures for each of the three
perfume qualities within a given year are determined. Due to the vast amount of missing
entries for the Transaction Year in the KNCPD, Panel Year, the term that denotes the
year in which the panel is conducted, appears on the x-axis of the graphs. Panel Year and
Transaction Year are assumed to roughly coincide.
28
Figure 1 presents the average shares of high, medium, and low quality fragrance
expenditures over the period 2004-2011, and the following discussion relates graphical
findings to the overall narrative.
Figure 1. Average Shares of Fragrance Expenditures.
Source: Kilts-Nielsen Consumer Panel Dataset (2004-2011). Notes: The y-axis shows the average shares of fragrance expenditures of each quality, over total fragrance expenditures. The x-axis shows the Panel Year, the year in which the panel is conducted, which, as explained, is assumed to roughly coincide with Transaction Year. The graph reveals the average shares of fragrances of low, medium, and high qualities consumed over 2004-2011. The Final Price Paid for Low Quality Fragrances is determined for each household within a given year. The Average Share of Expenditures on Low Quality Fragrances is calculated by dividing the sum of the Final Price Paid for Low Quality Fragrances by households in a given year, by the Final Price Paid for all fragrances in a given year and determining the mean. Similar procedures are repeated to create the Average Share of Expenditures on Medium Quality Fragrances and the Average Share of Expenditures on High Quality Fragrances. The averages of each of the aforementioned terms are determined. The square, triangle, and diamond patterned lines illustrate the average high, medium, and low quality fragrance expenditures as shares of the total fragrance expenditures.
Average household shares of expenditures on high quality fragrances steadily
increase from 2004-2010. Towards the end of the Great Recession, high quality fragrance
expenditures increase significantly. By contrast, the average share of medium quality
fragrance expenditures declines by more than 10 percent from 2004-2006 and increases

immediately before the recession. During the crisis, the average share of medium quality
fragrance expenditures drops and remains well below pre-crisis levels. The average share
of low-quality fragrance expenditures is stable prior to dropping sharply from 32 to about
25 percent from 2006-2007. Over 2007-2009, low quality fragrance expenditures increase
by approximately 10 percent, most likely due to households trading down towards
cheaper goods during the recession (Jaimovich, Rebelo, and Wong 2015). Overall, the
average share of high quality fragrances is largely unaffected. A possible explanation for
this puzzle is that households maintain or increase average shares of high quality
fragrance expenditures to sustain wellbeing or enhance attractiveness (see Gao, Kim, and
Zhang 2013; Hill et al. 2012). As expected, average shares of medium quality perfumes
decline, while those of low quality perfumes increase at the height of the Great Recession
(Dub, Hitsch, and Rossi 2015). Figure 1 supports the narrative that households substitute
away from medium quality perfumes, towards those of high and low qualities.
The following figures examine the behavior of high- and low-income households
with respect to their average shares of high, medium, and low quality fragrances over
time. Figure 2 presents the average share of high quality fragrance expenditures of U.S.
households within both income categories over 2004-2011.

The x-axis shows the Panel Year, the year in which the panel was conducted, which, as explained, is assumed to roughly coincide with Transaction Year. The graph reveals the average share of high quality fragrances consumed over 2004-2011. The Final Price Paid for High Quality Fragrances is determined for each household within a given year. The Average Share of Expenditures on High Quality Fragrances is calculated by dividing the sum of the Final Price Paid for High Quality Fragrances by the Final Price Paid for all fragrances in a given year. The Average Share of Expenditures on High Quality Fragrances is determined. The patterned lines illustrate the average share of high quality fragrance expenditures within each year by high- and low-income households.
As expected, wealthy households show greater average shares of high quality
fragrance expenditures over time, ranging from approximately 30 to 50 percent over
2004-2011. While the share of high-quality fragrance expenditures by wealthy
households slightly diminishes after 2006, low-income households increase their share of
expenditures on high quality fragrances from 2006-2011. Towards the end of the
recession, households of all income levels follow a similar pattern; the share of high
quality expenditures increases sharply as economic conditions improve. Figure 2 findings
are consistent with the narrative that low-income households benefit relatively more than

do high-income households from recession-induced deals on high quality fragrances.
Low-income households re-allocate relatively more time, than their high-income
counterparts, towards increasing shopping effort to lower expenditures (see BCG 2010;
Griffith et al. 2009, 2015; Nevo and Wong 2015). Low-income households reveal higher
price sensitivity, than do high-income households, and show a steeper increase in their
average share of high quality fragrance expenditures throughout the recession.
Figure 3 analyzes the movement of the average shares of medium quality
fragrance expenditures by low- and high-income households across all years.

The Share of Expenditures on Medium Quality Fragrances is calculated by dividing the sum of the Final Price Paid for Medium Quality Fragrances by households in a given year, by the Final Price Paid for all fragrances. The Average Share of Expenditures on Medium Quality Fragrances by households is then determined. The patterned lines illustrate the average shares of medium quality fragrance expenditures by high- and low-income households.

Low-income households, as compared to high-income households, exhibit slightly
greater average shares of medium quality fragrance expenditures in 2004. Households
across all income levels decrease average shares of medium quality fragrance
expenditures until 2006, a behavior attributed to the fact that during stable economic
times, consumers purchase more high, instead of medium, quality goods. Average shares
of medium quality fragrance expenditures experience a steep decline from 2008-2009 for
both income groups. In 2011, the share of medium quality fragrance expenditures is still
significantly lower than in the pre-crisis period.
While maintaining a stable average share of high quality fragrance expenditures
during the recession, high-income households significantly decrease their average share
of medium quality fragrances in 2008-2009. In 2010-2011, the average share of high
quality fragrance expenditures increases, while that of medium quality fragrances
declines for both income groups. Consistent with the narrative, Figure 3 suggests that
although high- and low-income groups decrease average shares of medium quality
fragrance expenditures during the recession, high-income households maintain a greater
share of medium quality fragrance expenditures at the height of the recession than do
low-income households. Opportunity cost of time falls across all income groups during a
recession (Griffith et al. 2009). The relatively higher opportunity cost of time of high-
income households most likely accounts for the fact that they search for deals less
frequently than low-income households. Since low-income households benefit more from
deals on high quality goods, they reduce their average share of medium quality fragrance
expenditures more than high-income households.
33
Figure 4 also supports the established hypothesis by conveying that the average
share of low quality fragrances increases across all income levels during the recession
(see Dub, Hitsch, and Rossi 2015; Jaimovich, Rebelo, and Wong 2015). Low-income
households account for the largest average share of low quality fragrance expenditures,
ranging from 27 to roughly 38 percent, over time. Starting in 2007, all income levels
increase average shares of low quality fragrance expenditures until 2009. Consumers alter
shopping behavior in favor of cheaper goods during the crisis.

Following 2009, the average share of low quality fragrance expenditures
decreases for low-income households. During the recession, high-income households
show a larger increase in the average share of low quality fragrance expenditures, as
compared to low-income households. Supporting the narrative, the relative higher
opportunity cost of time, cited by Griffith et al. (2009), most likely prompts the wealthy
to choose low quality fragrances, over seeking out deals on high quality fragrances, as a
time efficient way to reduce expenditures.
Graphical analysis reveals findings consistent with the established hypothesis.
Figure 2 implies that average shares of high quality fragrance expenditures remain
roughly stable in 2008-2009. By contrast, Figure 3 shows that households across all
income levels decrease their shares of medium quality fragrance expenditures, a pattern
that suggests substitution towards the most affordable, low quality perfumes. Figure 4
conveys an increase in the average share of low quality fragrance expenditures at the
height of the recession. Important, observed differences in the magnitudes of changes in
buying behavior of high- and low-income households support the narrative of this study.
Several key limitations arise in using the method of quality differentiation based
on the measure of Price Per Unit. The lack of information provided by the KNCPD on
the unit of measure of the fragrance presents a major challenge. The KNCPD offers a
measure of size, reported as CT or Count, which is vague and does not include details
on the individual bottle size of the fragrance in ounces. Due to lack of information, the
Price Per Unit variable does not accurately represent the price per ounce of a fragrance.
The dearth of adequate information aside, challenges also arise when grouping
fragrances into the three categories of quality segmented by price. Many perfumes
35
considered high quality, grouped as such based on Price Per Unit, may in fact be medium
quality perfumes priced to compete with high quality, Designer brands. Figure 2 most
likely includes medium quality fragrances in the high quality category. Therefore, the rise
in the average share of high quality fragrances from 2010-2011 may be due, in part, to a
possible increase in the average share of expenditures on certain medium quality
fragrances. On the other hand, certain high quality, Designer fragrances may fall into the
medium quality category, depending on the price and the retail channel in which they are
sold. For example, a discount store may sell high quality perfumes at cheaper prices than
would an upscale retailer. In addition, fragrance prices may fluctuate significantly over
time. BCG (2010) finds that in anticipation of, and during, a recession, many high-end
retailers slash prices of high quality goods; therefore, some high quality perfumes may
exist within the medium quality price category during the crisis. While graphical
interpretations largely support the established narrative, insufficient information, coupled
with price discrepancies, challenge the method of quality distinction by price.
i.ii.iii. Quality Differentiation by Brand
Considering the important drawbacks of the first method of quality
differentiation, this section introduces a second method used to segment fragrances.
Similar to reports generated by Euromonitor (2015, 2016) and The Boston Consulting
Group (2010) that categorize the luxury goods market into eight or nine sub-categories
for ease of analysis, this study segments the luxury sub-category of womens fragrances
based on brand. Unlike the price per ounce of a bottle of perfume, the status of a brand as
premium, mass-market, or private-label, is largely time invariant. The KNCPD UPC-
specific Brand Description variable provides either the name of the fragrance brand, the
36
name of the parent company, or both. Euromonitor generates annual market research
reports on fragrances in the United States and segments perfume brands into categories of
premium and mass-market. Table 6 presents a sample of the Euromonitor (2015)
database, which categorizes fragrance brands.
This study generates a new database that cross-references Euromonitor
information, and the relevant KNCPD Brand Description data, to categorize the KNCPD
fragrance transactions as either premium or mass-market. Complications arise since the
KNCPD Brand Description information does not always provide sufficient detail for
clear categorization. The Brand Description variable often lists only the name of the
perfume without accompanying information on the brand (e.g., Poison, instead of
Poison by Christian Dior) or only shows the parent company (e.g., Este Lauder or
Modern Muse, instead of Este Lauder Modern Muse) and does not provide both the
parent company and the perfume brand. The KNCPD information includes, in different
entries, content such as Coty Inc., as well as Davidoff and Calvin Klein, two of the
power or best-selling, high-end brands of the Coty (2014) portfolio. The Coty
Company Website (2014) conveys that Coty manufactures fragrances largely for mass-
market consumption; therefore, this study groups the fragrances with Brand Description
Coty Inc. as mass-market. Coty brands, such as Davidoff and Calvin Klein, which
Euromonitor categorizes as premium, are also considered premium in the newly created
database. Coty mass-market brands (e.g., Aspen) are grouped as such. Coty produces
mostly mass-market fragrances, yet the fragrances bearing a Brand Description that
refers to a premium power brand, are considered premium (Coty 2014). The same
grouping process is repeated for other parent companies and brands.

Notes: The table provides a sample of the database of fragrances, categorized as either premium or mass-market. The table conveys that certain parent companies have brand portfolios that include fragrances of premium and mass-market brands.
Although differentiating fragrances by brand is more effective than segmenting
quality by price, it is still important to acknowledge limitations. All perfume brands of
the parent company LVMH are considered premium. Contrastingly, Coty and Elizabeth
Arden produce premium and mass-market fragrances. However, the consumer may
perceive all Elizabeth Arden brands as premium and all Coty brands as mass-market.
Brand perception often determines whether fragrances are considered premium or mass-
market, yet this intangible cannot be taken into account. A robustness measure, using a
different categorization method, attempts to control for the aforementioned.
Several Nielsen Brand Descriptions contain nbl, an abbreviation corresponding
to no brand label, or private-label fragrances. Private-label products are sold under the
name of a small retailer and are generally more affordable than premium or mass-market
alternatives. An additional category, including private-label fragrances with UPCs
containing Brand Description nbl, is created. Segmenting quality by brand results in 49
premium brands, 26 private-label brands, and the remaining categorized as mass-market.

IV. Methodology
This section introduces the structure of the regression models, which are applied
to four distinct dependent variables for a comprehensive analysis of household shifts in
fragrance consumption in the periods prior to and during the Great Recession.
i. Presentation of the Regression Model
A series of regressions, differentiated by the dependent variable, determine the
consumption behavior of low- and high-income households over 2004-2011. The
majority of households do not remain in the dataset for all eight years under observation,
thus the regression analysis presents consumption patterns of households on the
aggregate. As one of the measures of robustness, the regression models are re-examined
using only households present for at least one year within each of the two time periods of
interest, the years 2004-2006, before the crisis, and the years 2008-2011, during the
crisis, to determine whether results and the overall narrative hold.
The first set of regressions measures the effect of independent variables on the
natural logarithm of the total fragrance expenditures in U.S. dollars by households within
a given year. Model I and its variations are as follows:
Model I.
(i) Ln(Total Fragrance Expenditures)HT7 = 0 + 1(RecessionT) + 0(YearT) + HT
(ii) Ln(Total Fragrance Expenditures)HT = 0 + 1(RecessionT) + 0(YearT) + 2(Income StatusH) + Demographics8 + HT
(iii) Ln(Total Fragrance Expenditures)HT = 0 + 1(RecessionT) + 0(YearT) + 2(Income
StatusH) + 3(RecessionT*Income StatusH) + Demographics9 + HT
7 The dependent variable, Ln(Total Fragrance Expenditures), is formed by taking the natural logarithm of the quantity of one added to the Final Price Paid, or the term denoting the total fragrance expenditures. The value of one is added such that households that abstain from purchasing fragrances of any particular type within certain years are still included. 8 Models I-IV (ii) include the continuous, demographic variables: Age of Head of Household and (Age of Head of Household)^2.

This study examines the behavior of households of two income categories within
two distinct time periods. In Models I-IV (i)-(iii), RecessionT is a categorical variable
equivalent to zero for the years 2004-2006 and equivalent to one for the period 2008-
2011. In Model I (i), should the coefficient, 1, exhibit negative, significance, then,
compared to total fragrance expenditures in the pre-crisis period, total fragrance
expenditures decline during the recession.10 Although documented as having ended in
June 2009, the recession, as Aguiar and Bils (2015) support, negatively impacted average
and median household income until 2012. YearT accounts for a linear trend in fragrance
expenditures, and should its coefficient, 0, reveal positive, significance, then fragrance
expenditures follow an upward trend over time. Income StatusH is an indicator variable
for households of either low- or high-income status. In Model I (ii), should 2 reveal
positive, significance, then high-income households, compared to low-income
households, contribute to greater increases in total fragrance expenditures. Subscripts H,
Household Code, and T, Panel Year, indicate expenditures by households and the year of
the expenditures, in that order, with Panel Year=T=2004,...,2011. Observations are
collapsed by Panel Year and by Household Code that identifies individual households.
Variation (iii), the most exhaustive of the regression models, builds on (ii) by
incorporating the interaction term RecessionT*Income StatusH and several additional
household demographic control variables. Interacting the RecessionT and Income StatusH
variables results in four distinct combinations of income level and time period: Pre-
Recession, Low-Income, Recession, Low-Income, Pre-Recession, High-Income,
9 Models I-IV (iii) include the demographic variables: Age of Head of Household, (Age of Head of Household)^2, Head of Household Employment, Head of Household Education, and Age and Presence of Children. Age of Head of Household and (Age of Head of Household)^2 are continuous variables; other demographic control variables are categorical. 10 Term coefficients in the log-linear regression Model I (i)-(iii) are associated with percent changes in the dependent variable. Conversely, linear regression Model II-IV (i)-(iii) outcomes are associated with percentage point shifts in the dependent variable.
40
and Recession, High-Income. RecessionT*Income StatusH, when considered in relation
to the dependent variable, designates fragrance expenditures by households of a particular
income group (e.g., high- or low-income) in a given period (e.g., before or during the
crisis). Output tables omit combinations containing either Pre-Recession or Low-
Income categories. Pre-Recession, Low-Income constitutes the base condition. In
Model I (iii), a sum of the individual coefficients, 1 and 3, on RecessionT and
RecessionT*Income StatusH that exhibits negative, significance would convey that high-
income households experience a significant percent decrease in fragrance expenditures
during the crisis. Conversely, a negative, significant difference between the RecessionT
and RecessionT*Income StatusH coeffcients, 1 and 3, would indicate that low-income
households significantly decrease total fragrance expenditures during the crisis.11
Regressions in Model I (i)-(iii) are then repeated with respect to the following
dependent variables: Average Share of Premium Fragrance Expenditures, Average Share
of Mass-Market Fragrance Expenditures, and Average Share of Private-Label Fragrance
Expenditures. The Average Share of Premium Fragrance Expenditures is created through
the following process. The Final Price Paid for Premium Fragrances is determined for
each household within a given year. The Share of Expenditures on Premium Fragrances
is calculated by dividing the sum of the Final Price Paid for Premium Fragrances by
households in a given year, by the Final Price Paid for all fragrances in a given year. The
Average Share of Premium Fragrance Expenditures is then determined.
11 A joint linear combination test is used to determine the significance of the combined effect of the RecessionT and RecessionT*Income StatusH terms on the dependent variable. The linear combination test and its results are discussed in Section V.

Model II.
(i) (Average Share of Premium Fragrance Expenditures)HT = 0 + 1(RecessionT) + 0(YearT) + HT
(ii) (Average Share of Premium Fragrance Expenditures)HT = 0 + 1(RecessionT) +
0(YearT) + 2(Income StatusH) + Demographics + HT (iii) (Average Share of Premium Fragrance Expenditures)HT = 0 + 1(RecessionT) +
0(YearT) + 2(Income StatusH) + 3(RecessionT*Income StatusH) + Demographics + HT
In Model II (iii), the sign and significance of the sum (difference) of the
coefficients on RecessionT and RecessionT*Income StatusH determines the impact, in
percentage points, of the Great Recession on the Average Share of Premium Fragrance
Expenditures by high-income (low-income) households, as compared to their pre-crisis
average share of premium fragrance expenditures.
Model III.
(i) (Average Share of Mass-Market Fragrance Expenditures)HT = 0 + 1(RecessionT) + 0(YearT) + HT
(ii) (Average Share of Mass-Market Fragrance Expenditures)HT = 0 + 1(RecessionT) +
0(YearT) + 2(Income StatusH) + Demographics + HT (iii) (Average Share of Mass-Market Fragrance Expenditures)HT = 0 + 1(RecessionT) +
0(YearT) + 2(Income StatusH) + 3(RecessionT*Income StatusH) + Demographics + HT
A procedure similar to that used to create the Average Share of Premium
Fragrance Expenditures, is repeated to generate the Average Share of Mass-Market
Fragrance Expenditures, the dependent variable presented in Model III. Should the sum
(difference) of the coefficients on RecessionT and RecessionT*Income StatusH in Model
III (iii) prove negative and significant, then high-income (low-income) households reduce
their average share of mass-market fragrance expenditures during the economic crisis.
42
Model IV.
(i) (Average Share of Private-Label Fragrance Expenditures)HT = 0 + 1(RecessionT) + 0(YearT) + HT
(ii) (Average Share of Private-Label Fragrance Expenditures)HT = 0 + 1(RecessionT) +
0(YearT) + 2(Income StatusH) + Demographics + HT (iii) (Average Share of Private-Label Fragrance Expenditures)HT = 0 + 1(RecessionT) +
0(YearT) + 2(Income StatusH) + 3(RecessionT*Income StatusH) + Demographics + HT
The final model measures the impact of the same independent variables, as in
Models I-III (i)-(iii), on the Average Share of Private-Label Fragrance Expenditures.
Should the sum (difference) of the individual coefficients on RecessionT and Income
StatusH in Model IV (iii) exhibit positive, significance, then high-income (low-income)
households increase their average share of private-label fragrance expenditures during the
Great Recession. Differences in the magnitudes of the shifts in expenditures by low- and
high-income households reveal the impact of household income on shopping behavior.

V. Results and Discussion
i. Graphical Analysis and Regression Results
This section engages in a side-by-side discussion of graphical and regression
analyses and offers plausible explanations for results to support the established narrative.
Fragrances are differentiated by brand type, rather than by price, using the method
previously specified. Interpretations of outcomes both from graphs, and corresponding
regression Models I-IV (i)-(iii), offer conclusions relevant for responding to the first and
second research questions.

Figure 5 illustrates the total expenditures, in U.S. dollars, on womens fragrances
for 2004-2011. The dependent variable is determined by calculating the sum of the Final
Price Paid, or the total amount, in U.S. dollars, spent on fragrances by households in
each year. In 2004, total household perfume expenditures reach about $60,000. After
