The Attention Cost of Stable Matching
Victor H. Aguiar, Dian Hong
In large markets, scarce attention limits partner evaluation and creates allocation loss, which stability magnifies. In an independent random market with average executable degree…
Tabular Foundation Models and the Unity of Economic Behaviour
Victor H. Aguiar
Economics uses different behavioural models for risk, time, losses, valuation, and social choice. I study a unified choice experiment in which the same decision makers face all the…
GARP-EFM: Improving Foundation Models with Revealed Preference Structure
Victor H. Aguiar, Nail Kashaev
Modern pretrained time-series foundation models can forecast without task-specific training, but they do not fully incorporate economic behavior. We show that teaching them basic e…
Entangled vs. Separable Choice
Nail Kashaev, Martin Plávala, Victor H. Aguiar
A judge observes the joint probabilistic choice rule of two decision makers: the frequency of action pairs across pairs of local covariates. The rule is separable if behavior can b…
Dynamic and Stochastic Rational Behavior
Nail Kashaev, Victor H. Aguiar, Martin Plávala +1
The (static) utility maximization model of Afriat (1967), which is the standard in analysing choice behavior, is under scrutiny. We propose the Dynamic Random Utility Model (DRUM)…
Nonparametric Analysis of Dynamic Random Utility Models
Nail Kashaev, Victor H. Aguiar
We study a dynamic generalization of stochastic rationality in consumer behavior, the Dynamic Random Utility Model (DRUM). Under DRUM, a consumer draws a utility function from a st…
Random Rank-Dependent Expected Utility
Nail Kashaev, Victor Aguiar
We present a novel characterization of random rank-dependent expected utility for finite datasets and finite prizes. The test lends itself to statistical testing using the tools in…
A Random Attention and Utility Model
Nail Kashaev, Victor H. Aguiar
We generalize the stochastic revealed preference methodology of McFadden and Richter (1990) for finite choice sets to settings with limited consideration. Our approach is nonparame…
Identification and Estimation of Discrete Choice Models with Unobserved Choice Sets
Victor H. Aguiar, Nail Kashaev
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 p…
A Rationalization of the Weak Axiom of Revealed Preference
Victor H. Aguiar, Per Hjertstrand, Roberto Serrano +1
Given a finite collection of choices over budgets, rational consumer behavior is identified with the generalized axiom of revealed preference (GARP). As an alternative, the weak ge…
Random Utility and Limited Consideration
Victor H. Aguiar, Maria Jose Boccardi, Nail Kashaev +1
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…
Stochastic Revealed Preferences with Measurement Error
Victor H. Aguiar, Nail Kashaev
A long-standing question about consumer behavior is whether individuals' observed purchase decisions satisfy the revealed preference (RP) axioms of the utility maximization theory…
Prices, Profits, Proxies, and Production
Victor H. Aguiar, Nail Kashaev, Roy Allen
This paper studies nonparametric identification and counterfactual bounds for heterogeneous firms that can be ranked in terms of productivity. Our approach works when quantities an…
