An important result in convex analysis is the duality between a closed convex set and its support function. We exploit this duality to develop a novel geometric approach to mechanism design. For a general class of social choice problems we characterize the feasible set, which is closed and...

We extend the equivalence between Bayesian and dominant strategy implementation established by Gershkov et al. (Econometrica, 2013) to environments with non-linear utilities satisfying the average single-crossing property and the convex-valued assumption. The new equivalence result produces...

We consider general social choice environments with private values and correlated types. Each agent's matrix of conditional probabilities satisfies the full rank condition. We show that for any Bayesian incentive compatible mechanism there exists a dominant strategy incentive compatible...

We study the bilateral trade problem put forward by Myerson and Satterthwaite (1983) under the assumption that agents are loss-averse, using the model developed by Koszegi and Rabin (2006, 2007). We show that the endowment effect increases the sellers information rent, and that the attachment...

Models of choice where agents see others as less sophisticated than themselves have significantly different, sometimes more accurate, predictions in games than does Nash equilibrium. When it comes to mechanism design, however, they turn out to have surprisingly similar implications. This paper...

Banking models in the tradition of Diamond and Dybvig (1983) rely on sequential service to explain belief-driven runs. But the run-like phenomena witnessed during the financial crisis of 2007-08 occurred in the wholesale shadow banking sector where sequential service is largely absent,...

This paper describes a mechanism designed to induce commercial banks to increase their willingness to extend loans in an economic environment characterized by increased uncertainty and diminished expectations. This mechanism is a new tool for the conduct of monetary policy to combat recessions.

The endowment and attachment effect are empirically well-documented in bilateral trade situations. Yet, the theoretical literature has so far failed to formally identify these effects. We fill this gap by introducing expectations-based loss aversion, which can explain both effects, into the...

Why do women hit the glass ceiling? Women are hired, but then fail to rise through the ranks. We propose a novel explanation for this pattern, namely preference- and belief-free discrimination. In our setting, an employer can increase effort by inducing differential value distributions for a...
