We propose and axiomatically characterize dynamically consistent update rules for decision making under ambiguity. These rules apply to the preferences with multiple priors of Gilboa and Schmeidler (1989), and are the first, for any model of preferences over acts, to be able to reconcile typical...

Among the reasons behind the choice behavior of an individual taking a stochastic form are her potential indifference or indecisiveness between certain alternatives, and/or her willingness to experiment in the sense of occasionally deviating from choosing a best alternative in order to give a...

Our understanding of risk preferences can be sharpened by considering their evolutionary basis. The existing literature has focused on two sources of risk: idiosyncratic risk and aggregate risk. We introduce a new source of risk, heritable risk, in which there is a positive correlation between...

I study endogenous learning dynamics for people who misperceive intertemporal correlations in random sequences. Biased agents face an optimal-stopping problem. They are uncertain about the underlying distribution and learn its parameters from predecessors. Agents stop when early draws are "good...

Economic agents care about their relative well-being, and the comparisons are usually local. We capture this using a network model, in which an agent's payoff depends on the ranking of their allocation among their network neighbors’. Given a network, an allocation is called α-stable if no...

Fertility rates are declining in many countries. But are fertility rates inefficiently low? This paper addresses this question by exploring the efficiency properties of equilibria in an overlapping generations setting with endogenous fertility and dynastic parental altruism, using a particular...

This paper explores the properties of the notions of A-efficiency and P-efficiency, proposed by Golosov, Jones and Tertilt (Econometrica, 2007), to evaluate allocations in a general overlapping generations setting in which fertility choices are endogenously selected from a continuum and any two...

Prominent research argues that consumers often use personal budgets to manage self-control problems. This paper analyzes the link between budgeting and self-control problems in consumption-saving decisions. It shows that the use of good-specific budgets depends on the combination of a demand for...

This article studies socially optimal allocations, from the point of view of a benevolent social planner, in environments characterized by fixed resources, endogenous fertility, and full information. Individuals in our environment are fully rational and altruistic toward their descendants. Our...
