Nested Pseudo-GMM Estimation of Demand for Differentiated Products
Victor Aguirregabiria, Hui Liu, Yao Luo
We propose a fast algorithm for computing the GMM estimator in the BLP demand model (Berry, Levinsohn, and Pakes, 1995). Inspired by nested pseudo-likelihood methods for dynamic di…
Identification and Estimation of Demand Models with Endogenous Product Entry and Exit
Victor Aguirregabiria, Alessandro Iaria, Senay Sokullu
Firms introduce products in markets where they anticipate stronger demand, using information unobserved by researchers. This creates endogenous selection in demand estimation. In d…
Decentralized Decision-Making in Retail Chains: Evidence from Inventory Management
Victor Aguirregabiria, Francis Guiton
This paper investigates the impact of decentralizing inventory decision-making in multi-establishment firms using data from a large retail chain. Analyzing two years of daily data,…
Dynamic demand for differentiated products with fixed-effects unobserved heterogeneity
Victor Aguirregabiria
This paper studies identification and estimation of a dynamic discrete choice model of demand for differentiated product using consumer-level panel data with few purchase events pe…
Dynamic Games in Empirical Industrial Organization
Victor Aguirregabiria, Allan Collard-Wexler, Stephen P. Ryan
This survey is organized around three main topics: models, econometrics, and empirical applications. Section 2 presents the theoretical framework, introduces the concept of Markov…
Identification of Average Marginal Effects in Fixed Effects Dynamic Discrete Choice Models
Victor Aguirregabiria, Jesus M. Carro
In nonlinear panel data models, fixed effects methods are often criticized because they cannot identify average marginal effects (AMEs) in short panels. The common argument is that…
Sufficient Statistics for Unobserved Heterogeneity in Structural Dynamic Logit Models
Victor Aguirregabiria, Jiaying Gu, Yao Luo
We study the identification and estimation of structural parameters in dynamic panel data logit models where decisions are forward-looking and the joint distribution of unobserved…
