We study frictionless matching models in large production economies with and without market imperfections and/or incentive problems. We provide necessary and sufficient distribution-free conditions for monotone matching which depend on the relationship between what we call the segregation payoff...

Increased competition tends to benefit all buyers with increasing product variety and decreasing prices. However, if local and external market channels compete for the same class of products, increased competition from the external market crowds out local variety. Under local monopoly, local...

Little is known theoretically, and even less empirically, about the relationship between firm boundaries and the allocation of decision rights within firms. We develop a model in which firms choose which suppliers to integrate and whether to delegate decisions to integrated suppliers. We test...

This paper critically assesses the implications of contract design and risk transfer on the provision of public services under public-private partnerships (PPPs). Two results stand out. First, the alleged strength of PPPs in delivering infrastructure projects on budget more often than...

This paper develops a unifying framework to understand competition issues in network industries. It focuses on the telecom(munication) industry and takes two specific effects of this industry into account. First, the telecom industry is in continuous evolution and alliances affect not only the...
