Applied research often tolerates misspecification in order to reach informative conclusions. We focus on how the degree of misspecification varies with the level of aggregation of data for quasilinear utility models. We present aggregation results formalizing that the model cannot get worse when...

Using a revealed preference approach, we conduct an experiment where subjects make choices from linear convex budgets in the domain of risk. We find that many individuals prefer mixtures of lotteries in ways that systematically rule out expected utility behavior. We explore the extent to which...

We provide revealed preference characterizations for choices made under various forms of costly information acquisition. We examine nonseparable, multiplicative, and constrained costly information acquisition. In particular, this allows the possibility of unknown time delay for acquiring...

Many theoretical models of stochastic choice are characterized by availability variation. Instead, most stochastic choice datasets have information on attribute values that vary across decision problems. This paper uses attribute variation to characterize a framework that encompasses existing...

Research estimating market supply often focuses on parametric models. In this paper, we study a non-parametric approach to market supply. We characterize the necessary and sufficient conditions of profit maximization for aggregate market behavior when participants on the supply side vary and...

Individual choices are often inconsistent with economic theories, which has motivated a variety of ways to measure how far choices are from a given theory. Recent work has investigated the correlation between measures of rationality and observable information such as education or income. This...

This paper studies when stochastic choices are consistent with behavior from Bayesian expected utility maximization and information acquisition. This is a limited dataset since other characterization require state-dependent stochastic choice data. The conditions that characterize this behavior...

This paper takes seriously that the quasilinear utility model is an approximation. We interpret approximation error as arising because individuals are satisficers. We investigate the consequences of individual satisficng for modelling aggregate demand, providing an approximate aggregation...
