In this paper we consider the problem of efficiently allocating a given resource or object repeatedly over time. The agents, who may temporarily receive access to the resource, learn more about its value through its use. When the agents' beliefs about their valuations at any given time are...

We consider a general screening model with payoff externalities and type-dependent feasibility constraints. The principal can design contract instruments of arbitrary dimension to influence each agent's valuation of the proposed transaction, which also depends on the anticipated choice of other...

We provide a technique for constructing optimal multiattribute screening contracts in a general setting with one-dimensional types based on necessary optimality conditions. Our approach allows for type-dependent participation constraints and arbitrary risk profiles. As an example we discuss...
