Likelihood Based Estimation of Nonlinear Equilibrium Models with Random Coefficients

In this paper we develop a likelihood based approach for estimating the equilibrium price and shares in markets with differentiated products and oligopoly supply. We model market demand using a discrete choice model with random coefficients and random utility. For most applications the likelihood function of equilibrium prices and shares is intractable and cannot be directly analyzed. To overco...

Bayesian Estimation of Random-Coefficients Choice Models Using Aggregate Data

This article discusses the use of Bayesian methods for estimating logit demand models using aggregate data. We analyze two different demand systems: independent samples and consumer panel. Under the first system, there is a different and independent random sample of N consumers in each period and each consumer makes only a single purchase decision. Under the second system, the same N consumers ...

Bayesian Estimation of Nonlinear Equilibrium Models with Random Coefficients

In this paper we develop a conditional likelihood based approach for estimating the equilibrium price and shares in markets with differentiated products and oligopoly supply. We model market demand using a discrete choice model with random coefficients and random utility. For most applications the likelihood function of equilibrium prices and shares is intractable and cannot be directly analyze...

Identifying Distributional Characteristics in Random Coefficients Panel Data Models∗

This appendix contains: identification and estimation results on higher-order moments (Section A), some results on efficiency bounds calculations (Sections B and C) and the computation of asymptotic standard errors (Section D); additional computations for the examples treated in the text (Section E); an outline of a test of the covariance structure of errors (Section F); the calculation of the ...
