We examine how owners of productive resources (e.g. public enterprises or financial capital) optimally allocate their resources among wealth-constrained operators of unknown ability. Optimal allocations exhibit: (1) shared enterprise profit--the resource owner always shares the operator's...

This paper presents a dynamic general equilibrium model of R&D-based trade between two structurally identical countries in which both innovation and skill acquisition rates are endogenously determined. Trade liberalization increases R&D investment and the rate of technological change. It also...

This paper presents a dynamic general equilibrium model of North-South trade in which research and development races between firms determine the rate of product innovation in the North. Tariffs designed to protect dying industries in the North from Southern competition reduce the steady-state...

In many important high-technology markets, including software development, data processing, communications, aeronautics, and defense, suppliers learn through experience how to provide better service at lower cost. This paper examines how a buyer designs dynamic competition among rival suppliers...

We extend William Rogerson's (2003) intriguing analysis of simple procurement contracts to settings where the supplier’s innate production cost is not necessarily distributed uniformly. Although the simple contract that Rogerson analyzes performs remarkably well when the smaller cost...
