PhD in Marketing Science or Consumer Behavior

At Olin, the marketing discipline is distinguished by a demand for innovative ideas, critical thinking and an emphasis on quantitative abilities.

PhD students in marketing typically choose one of the two areas of study: Marketing Science and Consumer Behavior. Some choose to analyze the intersection of the two areas seeking to improve understanding and predict marketing phenomena.

Marketing Science

Marketing Science focuses on the quantitative—economic fundamentals that include microeconomic theory and econometrics. Using this methodology, you examine mathematical modeling of buyer-seller interactions, consumer choices, purchase behavior, resource allocation, components of the marketing mix and new product development.

The methods below help you determine the best way to allocate marketing resources.

Conduct empirical tests on the implications of these models
Quantify the effectiveness of different strategies
Explore the profit implications of using alternative strategies

In Marketing Science, we conduct empirical tests on the implications of these models, quantify the effectiveness of different strategies and explore the profit implications of using alternative strategies. We identify important drivers that should govern strategic decisions and, consequently, the allocation of marketing resources.

Consumer Behavior

Consumer Behavior concentrates on psychology fundamentals and understanding how people make decisions, including cognitive psychology, social psychology and behavioral decision theory. These areas provide a strong foundation as you study and research consumer judgment and decision-making, cognition, culture, emotions, motivation, individual differences, perception and social influence.

Faculty members work on a variety of topics related to judgment and decision-making. Current and recent research topics include biases in judgment and choice, choice assortments, prosocial behavior, financial decision making, branding, intertemporal choice, morality and consumption, preferences for natural products, gift giving and metacognition.

Marketing Faculty and Research

Olin’s marketing faculty pursue research focused on building frameworks and models to understand and evaluate marketing strategies and their impact on customers, consumers and competitors. This research provides decision makers the ability to think beyond current practices and offers answers to significant "what if" questions.

Research papers by faculty members have recently been published in well-respected journals such as:

Marketing Science
Journal of Consumer Research
Journal of Marketing Research
Journal of Marketing
Marketing Letters
