Part I.
Intro to Conjoint Analysis
Ask people what they want, and they say, “the best of everything”.
Ask them what they would like to spend, and they say, “a little as possible”.
– Bryan K. Orme

• Bias toward high importance in ratings
• Lack of discrimination
• Different respondents use the scale differently

• Ask Direct Questions about preference:
- What brand do you prefer?
- What Interest Rate would you like?
- What Annual Fee would you like?
- What Credit Limit would you like?
• Answers often trivial and unenlightening (e.g. respondents prefer low fees to
high fees, higher credit limits to low credit limits)

CA Idea
• People cannot reliably express how they weight separate features of the
product/service
• But can evaluate the overall desirability of a complex product/service profile – a
more realistic approach
- Based on a function of the value of its separate (yet conjoined) parts
• We can break product/services into features (attributes & their levels)
• Based on how people evaluate the combined features (profiles) we can deduce
the preference scores people might have assigned to individual features of the
product/service
- That are the result of those overall evaluations
• A back-door, decompositional approach for estimating people‟s preferences,
rather than an explicit approach of simply asking people to rate, rank, .. separate
features

Mathematical Psycchology
- McFadden in 70‟s - Discrete choice methods McFadden, D. 1974. Conditional logit analysis of qualitative choice behavior. In P. Zarembka (ed.), Frontiers in
Econometrics, pp. 105-142. New York: Academic Press.

Research
- work of R. Johnson: • Johnson, R. 1974, May. Trade-off analysis of consumer values. Journal of Marketing Research
• 80‟s

- R. Johnson (at Sawtooth Software) released a software system Adaptive Conjoint Analysis (ACA)
• 90‟s
- Discrete Choice overtakes Traditional Conjoint methods • Commercial software released (SawtoothSoftware CBC)
• Application of of hierarchical Bayes (HB) methods to estimate individual-level models from discrete choice data (led by G. Allenby of the Ohio State University)
• 00‟s and beyond
- Maximum-Difference Scaling
- Adaptive Choice Based Conjoint (ACBC) software released by SawtoothSoftware in 2009

Two broad types of CA
• “Traditional” CA
- uses data collected from sequential ratings, rankings or graded (rated) paired
comparisons followed by an analysis using simple linear models
- Use of “choice simulators” to predict individuals‟ preferences and choices
• No Choices are observed
• Choice-based Conjoint Analysis (CBC).
- uses data collected from a series of choices (from “choice sets”), followed by an
analysis using probabilistic choice models.
- Use of choice simulators to predict individuals‟ preferences and choices
• Choices are observed

CA Terminology
• Attribute
- A feature of product/service: Brand, Price, Pack type,...
• Attribute Level
- A value or range of variation for an attribute:
• Coca Cola, Pepsi,..., 0.5€, 0.6€,..., 0,33 l Can, 0,5 l Plastic Bottle
• Profile / Concept
- A combination of attribute levels: Coca-Cola at 0.5€ in a 0,33 l Can
• Design
- the attribute combinations that make up product/service profiles/concepts and how
those profiles/concepts are combined within tasks.

Design
• Orthogonality:
- each level appears an equal number of times with every other level of different
attributes. (zero correlation between pairs of attributes)
• Level Balance:
- within each attribute, each level appears an equal number of times.
• Minimal Overlap:
- achieve maximum variation across levels of an attribute within a (choice) task
(try not to repeat a level).
• Designs which are orthogonal and balanced are optimally efficient.
• In the real world: well-balanced, "nearly orthogonal“ designs

CA Research Process
• Identify attributes that underlie consumer preferences for products/services.
• Select levels or values of each attribute to represent ranges of variation in real
markets
• Create product or service profiles generated from some type of experimental
design
• Administer to a sample of respondents
• Analyze the data
- Relative importance
- Utilities or Part-Worth's
- Simulations
- Optimizations

What can we do with Conjoint data?
• Base case predictions linked with descriptive data
- who chooses what?
• Great input for segmentation (cluster analysis, latent class,...)
• Simulations (what if?)
- Sensitivity analysis (what if? systematically)
• Optimizations (best configurations)
• A simulator mimics a certain situation, that may or may not happen in reality (like
a flight simulator).
• The purpose is to estimate the probable effects of products/services.
• For this, the simulator needs input
- Data to describe the situation (scenario definition)
- Data on how consumers react (utilities from conjoint)
- Definition of the calculation
• Changing (part of) this data will result in new scenarios and new output

Conjoint Analysis in the context of political research
Case studies:
Slovenian parliamentary elections 2000
Slovenian presidential elections 2002

The premise
• The outcome of presidential or party contest is influenced by many factors
- party identification, candidate personality, campaign strategy and tactics, financing,
etc.
• In a real „purchase situation‟, „consumers‟ do not make choices based on a
single attribute. Consumers examine a range of features or attributes and then
make judgments or trade-offs to determine their final purchase choice.
• This is just as true for the „choice‟ made in political situations, such as assessing
the viability of a candidate, determining the support of various political,
economic, social issues.
Product:
• Candidate (not „branded‟) / Political Party (not „branded‟ but with issues
positions)
• Political Parties / Candidates are:
- Managed as Products/Services
- Advertised as Poroduct/Services
- Communicated as Products/Services

Slovenian parliamentary elections 2000
• Determine issues relative importance to voters, the most and least popular
position on each issue, the impact of a given position on voting behavior, and
the relative strength of different candidate profiles.
• To do that, we asked each respondent to rate a series of hypothetical pair of
candidates who have either a „liberal‟, „centrist‟, or „conservative‟ position on
each of 5 issue categories.
• Issues were the subject of debate in the campaign, and the position descriptions
were determined from positions that the candidates have actually taken and
were exposed in the media.
• C.A.T.I., n = 601
• ACA

Slovenian parliamentary elections 2000
5 attributes & a total of 14 levels:
• History:
- Past injustices are settled, what is important
is the future
- There is no future unless we settle past
injustices
- The future must be a priority, but we must
never forget the past injustices
• Roman-Catholic church
- RCC should be included in the political
decision making
- RCC should be consulted only with the
essential political issues
- RCC must be excluded from political sphere
• Equalitarianism
- The state should determine maximum wage
of all managers in all companies
- The state should determine maximum wage
only of managers in state owned companies
- The state should not interfere with managers
wages
• Welfare
- Every single individual should take care of
his/hers social welfare (health care, pension
welfare,...)
- The state and every single individual should
take care of social welfare
- The state should take care of the whole
social welfare of its citizens
• Lustration
- Those who were appointed to management
positions by the former political system,
should stay there if they are capable and
qualified
- We should remove all those who were
appointed to management positions by the
former political system
• 10 pair
• 2 attributes in pair

• Determine issues relative importance to voters, the most and least popular
position on each issue, the impact of a given position on voting behavior, and
the relative strength of different candidate profiles.
- To do that, we asked each respondent to rate a series of hypothetical pair of
candidates who have either a „liberal‟, „centrist‟, or „conservative‟ position on each of
four issue categories.
- Issues were the subject of debate in the campaign, and the position descriptions
were determined from positions that the candidates have actually taken and were
exposed in the media.
• Determine relative importance of demographic characteristics of a presidential
candidate and the impact on voting behavior.
- To do that, we asked each respondent to rate a series of hypothetical pair of
candidates described with demographic characteristics.
• C.A.T.I., issues n = 750, demo n = 786
• ACA
