In this paper we study "investment tournaments," a class of decision problems that involve gradual allocation of investment among several alternatives whose values are subject to exogenous shocks. The decision-maker's payoff is determined by the final values of the alternatives. An important...

I investigate the issue of endogenous spillover of R&D information across firms through information exchange between their employees. Although the firms typically cannot observe and restrict communication between their employees in a direct way, they can regulate information flows through the...

In the United States, more than two-thirds of decedents with multichild families divide their estates exactly equally among their children. In contrast, gifts given before death are usually unequal. These findings challenge the validity of existing theories regarding the determination of...

The article addresses the issue of optimal organization of production. I compare three organizational forms: centralization (one agent produces different inputs), decentralization (each of two agents produces a different input and contracts directly with the principal), and delegation (two...

This paper studies an internet trading mechanism similar to the one described in Peters and Severinov (2001) in a market where traders values are interdependent. It is shown that under reasonable conditions this mechanism has a perfect Bayesian equilibrium which supports allocations that...

In this paper we study a large market in which sellers compete by offering auctions to buyers instead of simple fixed price contracts. Two variants of the model are studied. One extends a model first analyzed by Wolinsky (1988) in which buyers learn their valuations only after meeting sellers....

A multi-unit auction environment similar to Ebay is studied. Sellers who wish to sell a single unit of a homogenous good set reserve prices for their own independently run auctions. Buyers who hope to acquire a single unit bid as often as they like in a dynamic second price auction. When the...

We investigate the issue of implementation via individually rational ex-post budget-balanced Bayesian mechanisms. We demonstrate that all social choice rules that generate a nonnegative ex-ante surplus, including ex-post efficient ones, can generically be implemented via such mechanisms for any...
