A monotone function interval is the set of monotone functions that lie pointwise between two
fixed,-monotone functions. We characterize the set of extreme points of monotone function …

A private private information structure delivers information about an unknown state while
preserving privacy: An agent's signal contains information about the state but remains …

This paper examines how the equilibrium effects of a public option on the private market
impact its optimal design. I develop a model in which a policymaker can choose the quality …

We consider the problem of revenue-maximizing Bayesian auction design with several
bidders having independent private values over several items. We show that it can be …

Monotone function intervals are sets of monotone functions that are bounded pointwise
above and below by two monotone functions. We characterize the extreme points of such …

This paper characterizes extreme points of the set of incentive-compatible mechanisms for
screening problems with linear utility. Extreme points are exhaustive mechanisms, meaning …

We use majorization to model comparative diversity in school choice. A population of agents
is more diverse than another population of agents if its distribution over groups is less …

A principal can propose a project to an agent, who then decides whether to accept. Their
payoffs from launching the project depend on an unknown binary state. The principal can …

Targeting subsidies to maximize social objectives often requires screening potential
recipients on unobservable characteristics. We consider the case where a policy maker …

We study the structure of Pareto optimal mechanisms in settings where the planner
considers more than one objective criterion. Specifically, we (i) characterize mechanisms …
