    DISCRETE CHOICE MODELS WITH MULTIPLE UNOBSERVED CHOICE CHARACTERISTICS∗ BY SUSAN ATHEY AND GUIDO W. I MBENS1 Harvard University, U.S.A. Since the pioneering work by Daniel McFadden, utility-maximization-based multinomial response models have become important tools of empirical re-searchers. Applications. Marketing researchers use discrete choice models to study consumer demand and to predict competitive business responses, enabling choice modelers to solve a range of business problems, such as pricing, product development, and demand estimation problems. In market research, this is commonly called conjoint analysis.; Transportation planners use discrete choice models to .

    Limdep: Discrete Choice Models (DCM) • We usually study discrete data that represent a decision, a choice. • Sometimes, there is a single choice. Then, the data come in binary form with a ”1”representing a decision to do something and a ”0” being a decision not to do something. => Single Choice (binary choice models): Binary Data.   In this research, we provide a new method to estimate discrete choice models with unobserved heterogeneity that can be used with either cross-sectional or panel data. The method imposes nonparametric assumptions on the systematic subutility functions and on the distributions of the unobservable random vectors and the heterogeneity parameter.

    Unobserved product attributes, such as flavor quality, are important elements to consider when estimating the demand for gum. The estimation results suggest that gum is an inelastic product. A positive relationship between willingness to pay and unobserved quality was identified, implying that gum industry should be able to command a premium. Sorting and Hedonic Models Sorting/discrete choice model: I Consumers choose among a nite set of bundles that might not cover all combinations possible: max j2J X ij i ip j + ˘ j + " ij I Note that adding " ij makes each product \unique", and therefore inconsistent with the hedonic assumption.

Discrete choice models used in statistical applications typically interpret an unobservable term as the interaction of unobservable horizontal differentiation and idiosyncratic consumer preferences.

An implicit assumption in most such models is that all choices are equally horizontally differentiated. results in very little “congestion” in unobserved characteristic space and can be problematic Unobserved differentiation in common discrete-choice models (Discrete Choice Theory of Product dge,Mass.

Recently, discrete-choice models have received increasing attention in the theoretical literature on differentiated products oligopoly, either as a means of justifying particular.

Discrete-Choice Models of Demand In these lecture notes we present a framework for estimating demand in industries which are of particular interest for industrial organization. These are industries where • There are a large number of competing products (large relative to number of distinct producers) • Products are differentiated; no two.
