Motivated by the question of how one should evaluate professional election forecasters, we study a novel dynamic mechanism design problem without transfers. A principal who wishes to hire only high-quality forecasters is faced with an agent of unknown quality. The agent privately observes...

We develop a dynamic adverse selection model where a career-concerned buy-side analyst advises a fund manager about investment decisions. The analyst's ability is privately known, as is any information she learns over time. The manager wants to elicit information to maximize fund performance...

We examine a model of dynamic screening and price discrimination in which the seller has limited commitment power. Two cohorts of anonymous, patient, and risk-neutral buyers arrive over two periods. Buyers in the first cohort arrive in period one, are privately informed about the distribution of...

Practical or legal constraints often restrict auctions to being symmetric (anonymous and nondiscriminatory). We examine when this restriction prevents a seller from achieving his objectives. In an independent private value setting with heterogenous buyers, we characterize the set of incentive...

We study mechanism design in a setting where agents know their types but are uncertain about the utility from any alternative. The final realized utility of each agent is observed by the principal and can be contracted upon. In such environments, the principal is not restricted to using only...

We examine an environment where objects and privately-informed buyers arrive stochastically to a market. The seller in this setting faces a sequential allocation problem with a changing population. We characterize the set of incentive compatible allocation rules and provide a generalized revenue...

We analyze a dynamic market in which buyers compete in a sequence of auctions. New buyers and objects may arrive at random times. Buyers' private values, however, are not persistent. Instead, buyers draw new values in every period; equivalently, objects are heterogeneous but are drawn from the...
