Dworczak, Kominers, and Akbarpour (2021) study when certain market structures are optimal in the presence of heterogeneous preferences. A key assumption to apply the results is that the social planner knows the joint distribution of the value of the good and marginal value of money. We show that...

Using a laboratory experiment, we identify whether decision makers consider it a mistake to violate canonical choice axioms. To do this, we incentivize subjects to report which of several axioms they want their decisions to satisfy. Then, subjects make lottery choices which might conflict with...

This note studies necessary and sufficient conditions for consumer demand data to be generated by a symmetric utility function. We find that a dataset of prices and consumption decisions can be rationalized by a symmetric utility function if and only if the symmetrized dataset satisfies the...

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...

This paper studies aggregate complementarity without price or income variation. We show that for a class of utility functions, variation in non-price observables allows one to recover a measure of complementarity similar to Hicksian complementarity. In addition, the entire Slutsky matrix can be...

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...
