An analysis of a simple model of consumer decision making

The practical application of this prescriptive approach how people ought to make decisions is called decision analysisand is aimed at finding tools, methodologies and software decision support systems to help people make better decisions. In contrast, positive or descriptive decision theory is concerned with describing observed behaviors under the assumption that the decision-making agents are behaving under some consistent rules.

An analysis of a simple model of consumer decision making

Conjoint design[ edit ] A product or service area is described in terms of a number of attributes.

For example, a television may have attributes of screen size, screen format, brand, price and so on. Each attribute can then be broken down into a number of levels. Respondents would be shown a set of products, prototypes, mock-ups, or pictures created from a combination of levels from all or some of the constituent attributes and asked to choose from, rank or rate the products they are shown.

Each example is similar enough that consumers will see them as close substitutes, but dissimilar enough that respondents can clearly determine a preference.

Each example is composed of a unique combination of product features. The data may consist of individual ratings, rank orders, or preferences among alternative combinations.

As the number of combinations of attributes and levels increases the number of potential profiles increases exponentially. Consequently, fractional factorial design is commonly used to reduce the number of profiles that have to be evaluated, while ensuring enough data are available for statistical analysis, resulting in a carefully controlled set of "profiles" for the respondent to consider.

Types[ edit ] The earliest forms of conjoint analysis were what are known as Full Profile studies, in which a small set of attributes typically 4 to 5 are used to create profiles that are shown to respondents, often on individual cards.

Respondents then rank or rate these profiles. Using relatively simple dummy variable regression analysis the implicit utilities for the levels can be calculated. Two drawbacks were seen in these early designs. Firstly, the number of attributes in use was heavily restricted.

With large numbers of attributes, the consideration task for respondents becomes too large and even with fractional factorial designs the number of profiles for evaluation can increase rapidly.

In order to use more attributes up to 30hybrid conjoint techniques were developed. The main alternative was to do some form of self-explication rating of separate components before the conjoint tasks and some form of adaptive computer-aided choice over the profiles to be shown.

The second drawback was that the task itself was unrealistic and did not link directly to behavioural theory. In real-life situations, the task would be some form of actual choice between alternatives rather than the more artificial ranking and rating originally used.

Jordan Louviere pioneered an approach that used only a choice task which became the basis of choice-based conjoint analysis and discrete choice analysis. This stated preference research is linked to econometric modeling and can be linked to revealed preference where choice models are calibrated on the basis of real rather than survey data.

Originally choice-based conjoint analysis was unable to provide individual level utilities as it aggregated choices across a market.

This made it unsuitable for market segmentation studies. With newer hierarchical Bayesian analysis techniques, individual level utilities can be imputed back to provide individual level data. Information collection[ edit ] Data for conjoint analysis are most commonly gathered through a market research survey, although conjoint analysis can also be applied to a carefully designed configurator or data from an appropriately designed test market experiment.

Market research rules of thumb apply with regard to statistical sample size and accuracy when designing conjoint analysis interviews. The length of the research questionnaire depends on the number of attributes to be assessed and the method of conjoint analysis in use.Marketing Theories – Explaining the Consumer Decision Making Process.

Early economists, led by Nicholas Bernoulli, John von Neumann, and Oskar Morgenstern, puzzled over this question.

Beginning about years ago, Bernoulli developed the first formal explanation of consumer decision-making. Bite-size behavioral research for the world's top Decision-Makers. Decision making under risk is presented in the context of decision analysis using different decision criteria for public and private decisions based on decision criteria, type, and quality of available information together with risk assessment.
