We derive conditions on the learning environment - which encompasses both Bayesian and non-Bayesian processes - ensuring that an efficient allocation of resources is achievable in a dynamic allocation environment where impatient, privately informed agents arrive over time, and where the designer...

A committee decides by unanimity whether to accept the current alternative, or to continue costly search. Each alternative is described by a vector of distinct attributes, and each committee member can privately assess the quality of one attribute (her "specialty"). Preferences are heterogeneous...

Many economic situations involve the timing of irreversible decisions. E.g. People decide when to sell a stock or stop searching for a better price. We analyze the behavior of a decision maker who evaluates his choice relative to the ex-post optimal choice in an optimal stopping task. We derive...

Regret and its anticipation affect a wide range of decisions. Job-seekers reject offers while waiting for an offer to match their best past offer; investors hold on to badly performing stocks; and managers throw good money after bad projects. We analyze behavior of a decision-maker with...

We study matching policies in a dynamic exchange market with random compatibility, in which some agents are easier to match than others. In steady state this asymmetry creates an endogenous imbalance: hard-to-match agents wait for partners, while easy-to-match agents can match almost immediately...
