    Abstract   The massive influx of immigrants has played an essential role in the high

    growth of the Spanish economy during the period 1997–2007. The severe economic crisis

    that began in 2008 is characterized by high unemployment and reductions in consumption

    by households. This article uses the Household Budget Survey to empirically estimate

    changes in the consumption patterns of households as a result of the economic crisis,

    analyzing whether differential impacts exist according to the nationality of the household’s

    main breadwinner. Our results show that households with non-Spanish main breadwinnershave lower levels of pre-crisis consumption, greater decrease in consumption because of 

    the crisis and greater inequality in consumption levels.

    1 Introduction

    Immigration has played an essential role in the evolution of the Spanish economy in the

    last 15 years. The massive influx of immigrants contributed to the high growth of the

    Spanish economy during the period 1997–2007. The flow of young and middle-aged

    foreign labour force was sufficient to cover the labour needs of labour-intensive sectors

    with low qualifications, while it temporarily guaranteed the viability of the Spanish public

    pension system. Immigrant workers have been concentrated in sectors such as construction,

    domestic service, hotels/restaurants or agriculture and have recorded higher levels of 

    temporality and lower wages than natives (Laparra  2011; Oliver 2012).

    The severe economic crisis that began in late 2007, named the Great Recession, is

    characterised by high unemployment. The most affected groups are non-European citizens,

    the young, low-skilled workers and the long term unemployed. In addition, credit con-straints have severely affected households’ capacity to borrow money in order to maintain

    levels of consumption. Hence, it is expected that families have modified their levels and

    composition of consumption. In fact, changing consumption patterns is one of the strate-

    gies adopted by households to cope with the negative effects of the crisis (Martı́nez 2010;

    Velazco and Ballester  2010).

    Taking as reference the context of the crisis and the importance of immigration in the

    Spanish economy and society, the aim of this article is to identify changes in the con-

    sumption patterns of households produced during the Great Recession, analysing whether

    there are differential impacts according to the nationality of the main breadwinner of the

    household. The analysis is performed for the period 2006–2011, and in particular for

    3 years: 2006, 2008 and 2011. This allows us to compare the changes in consumption

    patterns over a time of economic growth in 2006, with another when the crisis began, in

    2008, and a third of severe crisis, 2011. This article includes both descriptive and

    econometric analyses.

    The main database used in the analysis is the Household Budget Survey (HBS). This

    survey provides annual information on the nature and purpose of consumer spending. It

    also contains variables that reflect the main characteristics of the households in the sample,

    allowing us to analyse consumption patterns of immigrant households in Spain. Specifi-

    cally, the variable used in this article to identify immigrants is the nationality of the mainbreadwinner (Spanish versus non-Spanish and people with dual nationality). To study the

    evolution of consumption patterns during the period 2006–2011 changes in real con-

    sumption per adult equivalent are studied for 12 expenditure groups.

    When analysing the Great Recession, the economic literature has focused on several

    aspects, such as the effects of the crisis on household incomes (Avram et al.  2013; Jenkins

    et al.   2012; Laparra and Pérez-Eransus   2012) or the changes in consumption behaviour

    amongst households in Spain (Martı́nez 2010). But in the economic literature there are no

    studies on the effects of the crisis on the consumption of immigrant households in Spain.

    Our work aims to fill this gap, focusing on a key effect of the crisis on this vulnerable

    group.The article is organised into five sections. The second section discusses the economic

    crisis and its impact on the population. The third one identifies both changes in patterns of 

    household consumption in Spain over a wide period prior to that studied in our article

    and the structure and changes in consumption patterns during 2006–2011. The econo-

    metric analysis of the determinants of per adult equivalent consumption is carried out in

    the fourth section. Finally, the conclusions are presented in the last section.

    The main results indicate that one of the key variables explaining changes in con-

    sumption patterns is the nationality of the main breadwinner. Compared to native house-

    holds, those with non-Spanish or dual nationality main breadwinner show lower levels of pre-crisis consumption, greater decrease in consumption because of the crisis (especially

    with respect to the less essential products), as well as greater and rising inequality in

    consumption levels.

    2 Migration and Economic Crisis

    2.1 Theories of International Immigration

    Different theoretical approaches, from diverse disciplines, have been developed to explaininternational migration.1 Regarding economics, neoclassical theory provides both macro

    and micro approaches. The former focuses on differential wages, employment conditions

    and migration costs between countries as leading factors enhancing migration flows (Harris

    and Todaro 1970). Alternative macroeconomic approaches are the Keynesian view, based

    on employment differentials between countries; the dual labour market theory, that

    explains migration as a result of structural labour market conditions in the destination

    country and in particular by the interest of local entrepreneurs to minimise labour costs by

    hiring cheaper immigrant workers for jobs that the local population do not want to take

    (Piore  1979).

    The microeconomic neoclassical approach corresponds to a typical model of individual

    choice. Under this context, individuals carry out a cost-benefit calculation, taking into

    account the expected incomes at the countries of origin and destination as well as immi-

    gration costs expecting a positive return as a result of international migration (Borjas  1990;

    Massey et al.  1993).

    Further developments have changed the focus beyond the individual as unit of analysis.

    Therefore, a new economics of migration has found it relevant to focus on the household as

    a decision-making unit. This approach highlights the migration action not as a result of an

    individual maximising profit decision but as a decision that involves both the migrant and

    the rest of their family. An implicit agreement is assumed whereby the family funds thetravelling cost of the migrant member and once they get a new job at the receiving country,

    remittances are sent to the family. This strategy is expected to enable a higher family

    income and migration of one or more members is a risk-reducing strategy for many

    households (Stark and Bloom 1985; Stark  1991). The relative deprivation concept is used

    as well to explain international migration. From this standpoint, migrants take into account

    relative income differentials towards the reference group in their country of origin when

    deciding to move abroad. This means that the poorest households in a community would

    have higher chances of moving abroad than middle or higher income groups (Stark and

    Taylor  1989).

    Another approach is the network theory. Its main emphasis is around the role of family,friendship, ethnic and kinship networks in shaping international migration patterns through

    lowering cost and risks of migration as well as increasing the expected net returns (Massey

    et al.   1993). Finally, the world system theory explains international migration as a by-

    product of the advances of capitalism and global markets, and particular by the core

    economies demand for cheaper labour and the surplus of labour in the periphery derived

    from increased productivity induced by foreign investment (Wallerstein  1974).

    2.2 International Immigration and the Spanish Labour Market

    Immigrants have played an important role in the stage of growth before the crisis. Their

    number increased from 0.51 to 4.11 million between 2000 and 2008, drawn by economic

    growth and labour demand that could not be satisfied because of the insufficient growth of 

    the local workforce. Moreno and López-Casasnovas (2006) have analysed the main factors

    1 A discussion on the relevant theories is found in Massey et al. (1993), Arango (2003) and Bijak (2011).

    Effects of the Great Recession on Immigrants’

     1 3

    that explain economic migration to Spain from 1994 to 2004, finding that differences in

    unemployment rates, poverty levels in the country of origin, knowledge of Spanish, geo-

    graphical distance, existence of immigrant networks in Spain and the degree of urbani-

    sation in the country of origin matter. The authors conclude that the microeconomic,

    Keynesian, dual labour market, world system and network theories are better suited forexplaining migration inflows from developing countries to Spain. Angoitia and Tobes

    (2013) describe the factors that can explain the huge immigration inflow that Spain reg-

    istered between 2000 and 2008. Economic growth, increased demand for labour, the

    regularisation processes and the role played by immigrant communities are underlined by

    the authors as the key elements driving immigration inflows to Spain. Hence, microeco-

    nomic, Keynesian, new economics of migration and network theories can help to explain

    that phenomenon.

    This growth of the immigrant population is among the highest in the EU-15 and the

    OECD, with a high proportion of non-EU and Latin American immigrants in particular

    (Laparra 2011; Mahı́a 2010). Within the Spanish territory, immigrants concentrate in areas

    with low unemployment, with high importance of the construction sector and with a large

    stock of immigrants (Maza et al.  2013).

    The sectors with the largest numbers of immigrants before the crisis were construction,

    domestic service, hotels/restaurants and agriculture, sectors requiring low skill lev-

    els. Immigrants showed higher activity and greater seasonality, which increased their

    vulnerability to changes in the economic cycle. Furthermore, immigrants had lower

    incomes than natives, since they had jobs requiring fewer skills, and higher levels of 

    deprivation (González and Segales 2013; Laparra 2011; Mahı́a 2010).2

    Moreover, there is non-economic migration, of people in the EU-15 looking to retire inSpanish territory (González and Segales 2013). Tables 1  and  2  record data about the 25

    most important countries of origin of people working in Spain in 2008. They show that

    there are clear differences between people migrating to Spain from developing and from

    developed countries. Salaries and the share of retired people confirm that people from poor

    countries tend to migrate to Spain looking for higher salaries, whereas for richer countries

    a higher share of people migrating for retirement is found. It is noteworthy that the

    unemployment rate does not seem to play any role in explaining migration flows to Spain.

    Hence, microeconomic theories seem to prevail in front of the macroeconomic perspective.

    The economic crisis has reduced inflows of immigrants and increased outflows. Those

    who return home are mainly the younger and the less resilient, with less dependants andgreater choices in their country of origin (such as the Latin American community) (An-

    goitia and Tobes 2013; Baliña et al. 2013; González and Segales 2013; Oliver 2012). Here

    again Keynesian, microeconomic and new migration theories seem able to explain inter-

    national migration flows.

    2.3 Economic Crisis in Spain

    The severe crisis affecting the Spanish economy since mid-2008 has its origin in excessive

    foreign borrowing linked to the real estate boom and to the improper supervision of theSpanish banking system. In addition, it should be noted that membership to the euro

    eliminates the possibility of devaluing the currency as a way to regain competitiveness, and

    2 It is noteworthy the large importance of illegal immigration, which reached a maximum of 47 % of the

    foreign population in 2005. The Spanish labour market, with a high importance of the shadow economy, and

    the inefficient application of immigration laws can explain this phenomenon (Laparra 2011; Mahı́a 2010).

     1 3

    that restrictive policies promoted by the EU to reduce budget deficits have also contributed

    to the decline in economic activity (Avram et al.  2013; Jenkins et al.   2012; Laparra and

    Pérez-Eransus   2012).

    Some data that reflect the intensity of the crisis are the following. Regarding macro-

    economic aggregates, the Spanish economy has experienced two stages of recession. The

    first spans over seven quarters between the second quarter of 2008 and late 2009. The

    second, from mid-2011, spans over nine quarters, until the second quarter of 2013.

    The Spanish labour market has been particularly affected by the hard fall in economic

    activity. This is especially noteworthy, since the main source of income in 2008 for nearly

    two-thirds of households in Spain came from wages (either self-employed or salaried

    employee). The unemployment rate has increased from 9.6 % (recorded in the first quarter

    of 2008) to 26.0 % (last quarter of 2013), peaking at 27.2 % in the first quarter of

    2013. The number of people employed has declined from 20.40 million to 16.76 million (a

    decrease of 17.9 %). The decline in employment has been more intense in the case of 

    foreigners, since the number of employed foreigners has decreased from 2.94 million in the

    first quarter of 2008 to only 2.01 in the last quarter of 2013, which  implies a reduction of 

    31.5 %. The unemployment rate of foreigners is currently 36.6 %.3 In this sense, immi-

    grants, with higher levels of insecurity, have acted as a collective that has absorbed the

    economic shock in the labour market (Laparra  2011).Poverty, deprivation and inequality have been on the rise since the inception of the

    depression. The moderate poverty risk has risen by two percentage points since 2007,

    people making meet ends with great difficulty by seven and a half points and the Gini

    coefficient of inequality by three points.

    The studies for Spain on the effects of the crisis on household well-being come to

    several conclusions. Firstly, in the labour market, and in addition to the increase in the

    unemployment rate highlighted above, unemployment is particularly affecting the mainbreadwinners, leading to a significant reduction of households’ income. Secondly, levels of 

    deprivation, poverty and inequality have increased with the outbreak of the crisis (Ayala

    et al. 2010; Laparra and Garcı́a 2010). The groups most affected by the crisis have been the

    young (González-Bueno et al.   2012), women, people with low education levels and

    immigrants. Moreover, Alegre and Pou (2013) find that job loss by the main breadwinner

    reduces household spending and that unemployment benefits do not allow households to

    maintain former spending levels.

    Furthermore, as Ayala (2013) notes in a study of seven developed countries, both Spain

    and Italy are the two cases where households’ disposable income fell between 2007 and

    2011, a fact that has not happened in the UK, USA, Germany, France and Sweden. In

    addition, Spain shows the most regressive distribution of income, with growth rates sig-

    nificantly below average for the lowest percentiles for 2006–2011. Ayala (2013) attributes

    this evolution to both changes in the Spanish labour market, through rising unemployment

    for the main breadwinners and wage inequality, as well as the limited capacity of redis-

    tribution of the Spanish tax and benefits system. Regarding the latter factor, Álvarez et al.

    (2013) note that the labour reforms of 2010 and 2012, the decline in the coverage for

    unemployment benefits and the reduction of expenditure on active policies have reduced

    the capacity of compensation of labour institutions.4

    Existing studies on the effects of the crisis on migrants in the labour market show thatforeigners are amongst the most negatively affected groups, since the unemployment rate

    in this group has increased more than for nationals, even though there is no negative

    discrimination towards them in regard to redundancies (Medina et al.   2010). However,

    foreigners are more likely both to be unemployed (Angoitia and Tobes 2013; Álvarez et al.

    2013) and to be long-term unemployed (Álvarez et al.  2013). This latter feature appears

    with the crisis.5

    The most adversely affected group is that of African men, while foreigners with longer

    residence period are less likely to be unemployed (Rinken et al.  2012; Angoitia and Tobes

    2013). Focusing on young people, it is detected that the negative evolution of the labour

    market has affected very similarly both the native and non-native labour force (Observa-torio Permanente Andaluz de las Migraciones 2012).

    3 Structure and Changes in the Consumption Patterns of Households in Spain

    The previous section of the article has analysed the important role played by immigrants in

    the Spanish economy over the last 15 years as providers of labour force as well as the

    intense and negative effects of the Great Recession on Spanish households. Against this

    4 A different view is suggested by Cantó  (2013), who concludes that the Spanish system of benefits and

    taxes has seen an increase in its capacity of redistribution between 2005 and 2011, due to increases in

    income tax and the emergence of an unemployment allowance for the long-term unemployed (Programa

    Prepara).5 Arranz and Garcı́a-Serrano (2013) find that there is a positive wage differential for European immigrants,

    which has increased since the beginning of the crisis.

    background, this section deals with several aspects linked to consumption patterns in

    Spain. Firstly, it describes trends on household consumption in Spain over a period of 

    50 years prior to the Great Recession. Secondly, the article describes the methodology and

    the database used in our empirical analysis. Thirdly, and based on empirical data for 2008,

    a comparison of main characteristics between immigrant and native households in Spain iscarried out. Fourthly, the evolution of consumption patterns for the whole Spanish pop-

    ulation as well as for the native and immigrant population (Spaniards and others) is deeply

    analysed. Finally, an analysis of inequality in consumption within both groups (Spaniards

    and others) is performed.

    3.1 Consumption Patterns of Households in Spain: from 1958 to 2005

    When focusing on household expenditure in Spain, interesting patterns are observed

    regarding expenditure groups. Table 3 shows the evolution of the average expenditure per

    person according to the five old expenditure groups for the country (food, clothing and

    footwear, dwelling, household expenditures and miscellaneous) from 1958 to 1996. The

    consumption structure is typical of a poor economy, in which most of the household

    spending is intended to cover their basic needs. Note how in 1958 households in Spain

    earmarked more than 60 % of their spending to food and clothing and footwear. In 1996

    that percentage had halved.

    Between 1998 and 2005, the share of expenditure on food and beverages continued to

    decline, whereas bills and other products show the opposite trends, as depicted in Table  4.

    In this table the new twelve expenditure groups (food and non-alcoholic beverages,

    alcoholic beverages and tobacco, clothing and footwear, bills, furniture and householdequipment, health, transport, communications, leisure and culture, education, hotels and

    restaurants and others) have been used.

    3.2 Database and Methodology

    The main database used in the analysis is the HBS. This survey was started in January

    2006 and provides annual information on the nature and purpose of consumer spend-

    ing. The survey provides estimates of annual consumption expenditure for Spain and its

    regions. It also contains variables that reflect the main characteristics of the sample

    households, the main source of regular income for households, the production branchwhere the main breadwinner works, the type of contract of the breadwinner, as well as age,

    nationality or educational level. Therefore, the HBS has variables that allow us to analyse

    the consumption patterns of immigrant households in Spain. The sample size is about

    24,000 households per year. Each household remains in the sample for two consecutive

    years, and every year half of the sample is renewed.

    The analysis is performed for the period 2006–2011, particularly for the years 2006,

    2008 and 2011. This allows us to study variations in the consumption patterns of house-

    holds in Spain over a period of change, since data is collected for a year of economic

    growth (2006), the start of the crisis (2008) and a year of severe crisis (2011). We performboth descriptive and econometric analyses. To study the evolution of consumption patterns

    during the period 2006–2011, changes in real consumption per adult equivalent are ana-

    lysed according to the new twelve groups of consumption. The conversion of the house-

    hold data from the nominal level found in the HBS is carried out using the modified

    divided according to occupational category, educational level, nationality (Spanish/non-

    Spanish) of the main breadwinner, among other variables.

    It should be noted that in our analysis we cannot use the variable ‘‘foreign nationality of the

    main breadwinner’’ because of the change of classification recorded in 2011 for people with

    Romanian or Bulgarian passports, a fact that does not allow a uniform comparison throughout

    the period. The variable used is ‘‘nationality of the main breadwinner’’, which allows us to

    distinguish between people with Spanish nationality and people with other nationalities (dual

    nationality and foreign nationals). The latter group contains immigrant individuals. To

     justify this decision we calculated the correlation coefficient between the variable ‘‘nation-

    ality of main breadwinner’’ and ‘‘place of birth of the main breadwinner’’. This correlation is

    0.9, indicating that, in practical terms, they include the same information. The variable

    ‘‘birthplace of the breadwinner’’ is not available for the years 2006 and 2008.

    As a part of the econometric approach, a reduced form of consumption function per adult

    equivalent (in logs) at the household level is estimated by ordinary least squares (OLS).

    3.3 Profile of Immigrants

    The 2008 HBS is used to present a profile of the immigrant household head (main

    breadwinner) in relation to the native one in Spain. The results, shown in Table  5, suggest

    a high degree of commonality in the gender composition, on average, 75 % are men and

    Table 8  depicts how Spaniards and other people (non-Spaniards and dual nationality)

    were allocating consumption into the 12 groups of products in 2008.

    The main result to be drawn from Table 7 is that the consumption of Spanish house-

    holds is significantly higher compared to non-Spaniards and people with dual nationality,

    for both total consumption and for different product groups. However, there are three

    groups of products that do not follow this pattern. On the one hand, two for which there is

    no significant difference in spending: alcohol and tobacco and transportation. On the other

    hand, communications spending appears to be significantly higher for non-Spaniards.

    Figure  1 shows that the evolution of expenditures of immigrants in major expenditure

    groups for the period 2008–2011 has been worse than in the case of Spaniards. A most

    marked difference exists for luxury goods, such as leisure or restaurants, while for basic

    products such as food, clothing or bills the differences are lower or even in favour of 

    immigrants.

    Finally, the comparison of expenditures at home and away from home of food and

    beverages reveals that non-Spaniards have reduced spending in restaurants by a greater

    proportion than Spaniards. The ratio of expenditure on food and drinks in restaurants on

    total expenditure on food and beverages decreased by an average 1.7 % per year for

    Spaniards during the period 2008–2011, while for non-Spaniards and people with dual

    nationality it fell by 5.5 %. All these findings show a greater tendency of immigrant

    households to reduce less important expenditure.

    3.6 Inequalities in Consumption

    A final aspect to be discussed in this section is to what extent differences in consumptionwithin the two groups studied (Spaniards and others) are significant. Figure 2   shows,

    through a Kernel density function of consumption per adult equivalent in real terms in

    2008, that the consumption distribution is more concentrated in the case of non-Spaniards

    as well as for those with dual nationality. Furthermore, this group is concentrated around

    lower consumption values than Spaniards.

    Table 9   allows us observe how inequality in the level of consumption has increased

    significantly in the case of individuals of other nationalities, since the value of the Gini

    index has risen from 0.259 in 2008 to 0.290 in 2011, while the variation in the case of 

    Spaniards was virtually nil. From these results it can be concluded that the economic crisisthat began in 2008 has eroded consumption levels and has had a regressive impact for non-

    Spaniards.

    Table 10 expands the previous analysis and shows the fall in consumption the bottom

    two quintiles of other nationalities, which explains the increase in inequality occurred in

    this group.

    4 Analysis of the Determinants of Household Consumption in Spain

    Studies of consumption in Spain using micro data at the household level have attempted to

    test the implications of the life cycle theory with rational expectations and liquidity con-

    straints (López-Salido   1993). Moreover, it has been analysed, at the regional level, the

    implications of the permanent income hypothesis (Gómez and Pérez 2005). Other relevant

    topics include analysing the empirical estimates, in the context of intertemporal decisions

    models, of the relationship between the degree of short-term self-control of consumers andtheir consumption and saving decisions (Collado et al.   2003), as well as the household

    spending response to anticipated changes in income (Browning and Collado  1999).6

    Barceló and Villanueva (2010) study to what extent individuals exposed to risk of losing

    their job delay consumption and accumulate more assets to build buffer stock of sav-

    ings. Casado (2011) investigates the degree of consumption insurance with respect to

    transitory and permanent income shocks. The capacity of insurance mechanisms for

    smoothing consumption changes is assessed and the role of family transfers is emphasised

    as smoothing strategy. Another important finding is the profile of those households facing

    difficulties for full insurance from permanent or transitory shocks. As expected, younger

    and low wealth households exhibit partial insurance to income shocks.

    This section follows the empirical approach of Castillo et al. (1998) when estimating aconsumption function to evaluate the consumption loss experienced by the unemployed

    workers relative to employees in Portugal and Spain. Furthermore, the analysis follows the

    lines of Adiego and Ayala (2013). That is, regressions for the years considered are esti-

    mated in order to determine the role of different explanatory variables on households

    expenditure per adult equivalent. In our case, the emphasis is on identifying the relevance

    of the specific characteristics of each household, the main breadwinners and their partners

    (where appropriate) to determine household expenditure per equivalent adult. In order to

    do so, consumption regressions corresponding to the years 2006, 2008 and 2011 are

    estimated.

    Overall, we estimate the following reduced form of a consumption function at the

    household level:

    C i ¼ bo þ b1 xi þ ei;  ei  NIDð0;r2Þ ð1Þ

    where   C i   is the logarithm of consumption per adult equivalent of the household,   xi   is a

    vector of household and the main breadwinner characteristics, among other variables.  b1 is

    a set of parameters that capture the effect of   xi  on   Y i. In addition,   b0   is the inter-

    cept and  ei  is the error term for household  i, which we assume to have independent normal

    distribution with zero mean and variance  r2.

    More specifically, the explanatory variables contained in Table 10   are taken intoaccount. Note that household income is not included as an independent variable. Initially,

    a model was specified with income as independent variable and, given the endogeneity

    between spending and household income, education level of the main breadwinner was

    used as an instrumental variable for household income per adult equivalent (in

    logs). However, this approach introduced multicollinearity in the model, so that estimates

    led to results inconsistent with economic logic. Finally, we chose two model specifications.

    The first one includes all the variables, with the exception of those referring to the partner

    of the main breadwinner. The second specification includes all the variables.

    Estimation is done by OLS using a heteroskedasticity robust estimator of the variance–

    covariance matrix. The results of the estimates for the years 2006, 2008 and 2011 are

    presented in Table 11. The fit is good (Adjusted R-squared above 0.29 for all years and

    specifications) and the vast majority of variables are statistically significant at the indi-

    vidual level, so that the hypothesis that the coefficients of each specification are jointly

    zero can be ruled out (the   p   value of the   F    test is less than 0.001 for all
