We unify and expand the theory of consumer’s behavior, based on Samuelson’s Weak Axiomof Revealed Preference, to permit simultaneously both random choice and non-singletonchoice sets. We provide a consistency postulate for demand behavior when such behavior isrepresented in terms of a...

This paper specifies and estimates a structural dynamic model of consumer demand for newand used durable goods. Its primary contribution is to provide an explicit estimationprocedure for transaction costs, which are crucial to capturing the dynamic nature ofconsumer decisions. In particular,...

Consumers' inflation expectations play a key role in the monetary transmission mechanism. As such, it is crucial for monetary policymakers to understand what they are and how they are formed. In this paper we introduce the (un)certainty channel as means to shed light on some of the more puzzling...

Asset demand tests for Expected Utility have almost universally been implemented in contingent claim settings where markets are complete. However when markets are incomplete, these tests cannot be applied since contingent claim prices cannot be uniquely recovered from given asset prices and the...

Probability weighting is often used to explain insurance choices that conflict with expected utility (EU) preferences. We derive new theoretical results on the effects of probability weighting in the context of common insurance demand puzzles. We identify decreasing relative overweighting (DRO)...

The evidence from many experiments suggests that people are heterogeneous with regard to their abilities to make rational, forward looking, decisions. This raises the question when the rational types are decisive for aggregate outcomes and when the boundedly rational types shape aggregate...
