Journal Article Journal of Business and Economic Statistics · January 1, 2025 We propose a framework for nonparametric identification and estimation of discrete choice models with unobserved choice sets. We recover the joint distribution of choice sets and preferences from a cross-section of repeated choices. We assume that either t ... Full text Cite

Prices, profits, proxies, and production

Journal Article Journal of Econometrics · August 1, 2023 This paper studies nonparametric identification and counterfactual bounds for heterogeneous firms that can be ranked in terms of productivity. Our approach works when quantities and prices are latent, rendering standard approaches inapplicable. Instead, we ... Full text Cite

Identification and Estimation of Multinomial Choice Models with Latent Special Covariates

Journal Article Journal of Business and Economic Statistics · January 1, 2023 Identification of multinomial choice models is often established by using special covariates that have full support. This article shows how these identification results can be extended to a large class of multinomial choice models when all covariates are b ... Full text Cite

Random utility and limited consideration

Journal Article Quantitative Economics · January 1, 2023 The random utility model (RUM, McFadden and Richter (1990)) has been the standard tool to describe the behavior of a population of decision makers. RUM assumes that decision makers behave as if they maximize a rational preference over a choice set. This as ... Full text Cite

A random attention and utility model

Journal Article Journal of Economic Theory · September 1, 2022 We generalize the stochastic revealed preference methodology of McFadden and Richter (1990) for finite choice sets to settings with limited consideration. Our approach is nonparametric and requires partial choice set variation. We impose a monotonicity con ... Full text Cite

Random Rank-Dependent Expected Utility

Journal Article Games · January 1, 2022 We present a novel characterization of random rank-dependent expected utility for finite datasets and finite prizes. As a byproduct, we obtain a characterization of random expected utility that works for finite datasets. The test lends itself to statistica ... Full text Cite

Stochastic Revealed Preferences with Measurement Error

Journal Article Review of Economic Studies · July 1, 2021 A long-standing question about consumer behaviour is whether individuals' observed purchase decisions satisfy the revealed preference (RP) axioms of the utility maximization theory (UMT). Researchers using survey or experimental panel data sets on prices a ... Full text Cite

Discerning Solution Concepts for Discrete Games

Journal Article Journal of Business and Economic Statistics · January 1, 2021 The empirical analysis of discrete complete-information games has relied on behavioral restrictions in the form of solution concepts, such as Nash equilibrium. Choosing the right solution concept is crucial not just for the identification of payoff paramet ... Full text Cite
