In this article, the authors offer a methodology to decompose the effects of price promotions into brand switching, stockpiling, and change in consumption by explicitly allowing for consumer heterogeneity in brand preferences and consumption needs. They develop a dynamic structural model of a...

We derive necessary and sufficient conditions for data sets composed of state-contingent prices and consumption to be consistent with two prominent models of decision making under ambiguity: variational preferences and smooth ambiguity. The revealed preference conditions for the maxmin expected...

We study the household portfolio allocation in an economy with a history of nominal anchor volatility. Applying smooth ambiguity preferences to a static portfolio choice problem, we rationalize two facts about the Argentine experience of the last 20 years: the dollarization of household...

This paper makes explicit the role of the entrepreneur in a consumer producer economy. Entrepreneurial behavior changes the status quo by altering existing comparative advantages. A positive feedback effect with trading institutions ensues. This model shows how the entrepreneur can, when...

Historical puzzles and paradoxes have been accepted by practitioners and researchers as evidence of irrationality on the part of the individual. However, when classifying these anomalies into similar structural ambiguities we note the consistency of individuals' distaste for ambiguity....

A popular argument about economic policy under uncertainty states that decentralisation offers the possibility to learn from local or regional policy experiments. We argue that such learning processes are not trivial and do not occur frictionlessly: Voters have an inherent tendency to retain a...

We consider an experimental setting where agents receive one stylized piece of information at a time about the value of a lottery. We find that Knightian uncertainty about the prior distribution of true lottery values does not hamper decision making by agents and markets. On a mean squared error...

We define coherent-ambiguity aversion within the Klibanoff, Marinacci and Mukerji (2005) smooth ambiguity model (henceforth KMM) as the combination of choice-ambiguity aversion and value-ambiguity aversion. We analyze theoretically five ambiguous decision tasks, where a subject faces two-stage...
