Abstract

This course will survey techniques used in modeling discrete data. Discrete choice models have become an essential tool in modeling individual behavior. The techniques are used in all social sciences, health economics, medical research, marketing research, transport research, and in a constellation of other disciplines. This course will examine several models and techniques used in these studies. We will begin with a brief review of regression modeling concepts, then turn to the fundamental building block in discrete choice modeling, the binary choice model. Several variants and extensions will be discussed before we turn attention to ordered choice models and models for counts. The second half of the course will be devoted to multinomial choice models of the sort used, e.g., in modeling brand choice in marketing, travel mode choice in transport, and a huge variety of applications in the social and behavioral sciences. Students in this course will obtain background in both the theory and methods of estimation for discrete choice modeling. This course will provide a gateway to the professional literature.

 

Course Outline

This is a course in econometric analysis of discrete data. There are a huge variety of models that are used in this context. We will focus on four which arguably comprise the foundation for the area: the fundamental model of binary choice (and a number of variants); models for ordered choices; the Poisson regression model for count data; and the fundamental model for multinomial choice, the multinomial logit model. Discussions will cover the topics listed below.

 

Prior knowledge is assumed to include calculus at the level assumed in the first year of a Ph.D. program in economics and a course in econometrics at the beginning Ph.D. level using a textbook such as Greene, W., Econometric Analysis, 6th edition.

 

No specific textbook is assigned for the course. A useful reference is

 

Applied Choice Analysis by Hensher, D., Rose, J. and Greene, W., (Cambridge University Press,2005).

 

Some of the presentation will be based on Econometric Analysis, 6th ed., by Greene, W. (Prentice Hall, 2003). Four chapters are included with the course materials: Left click to activate. Right click to download

The received literature on discrete choice models is vast – one could easily compose a list of thousands of articles. Your course materials include a small handful of articles, mainly for the purpose of illustrating particular techniques or ideas. (Working papers are attached. Most of these have been published elsewhere.) These are:

 

“Economic Choices,” American Economic Review, McFadden, D. (2001). McFadden’s Nobel Prize lecture.

“Mixed MNL Models for Discrete Response,” McFadden, D. and Train, K., Journal of Applied Econometrics, 2000.

“The Behaviour of the Maximum Likelihood Estimator of Limited Dependent Variable Model in the Presence of Fixed Effects,” Greene, W., Econometrics Journal, 2004.
