Contractual theories of vertical integration derive firm boundaries as an efficient response to market transaction costs. These theories predict a relationship between underlying features of transactions and observed integration decisions. There has been some progress in testing these...

Using the universe of large Canadian manufacturing firms in 1988 and 1996, we investigate to what extent outsourcing decision can be explained by a simple property rights model. The unique availability of disaggregate information on outputs as well as inputs permits the construction of a very...

Procurement contracts are often incomplete because the initial plans and specifications are changed and refined after the contract is awarded to the lowest bidder. This results in a final cost to the buyer that differs from the low bid, and may also involve significant adaptation and...

In labor markets, the ratchet effect refers to a situation where workers subject to performance pay choose to restrict their output, because they rationally anticipate that firms will respond to higher output levels by raising output requirements or cutting pay. We model this effect as a...

We analyze how variations in contractibility affect the design of contracts in the context of biotechnology research agreements. A major concern of firms financing biotechnology research is that the R&D firms might use the funding to subsidize other projects or substitute one project for...

Accountable Care Organizations (ACOs) are new organizations created by the Affordable Care Act to encourage more efficient, integrated care delivery. To promote efficiency, ACOs sign contracts under which they keep a fraction of the savings from keeping costs below target provided they also...

Can we identify the members of a community who are best- placed to diffuse information simply by asking a random sample of individuals? We show that boundedly-rational individuals can, simply by tracking sources of gossip, identify those who are most central in a network according to "diffusion...

This paper studies costly network formation in the context of risk sharing. Neighboring agents negotiate agreements as in Stole and Zwiebel (1996), which results in the social surplus being allocated according to the Myerson value. We uncover two types of inefficiency: overinvestment in social...

We examine how participation in a microfinance program diffuses through social networks. We collected detailed demographic and social network data in 43 villages in South India before microfinance was introduced in those villages and then tracked eventual participation. We exploit exogenous...

In settings with poor formal contract enforcement, profitable investments are likely unrealized. While social closeness can mitigate contractual incompleteness, we examine how to improve the preponderance of cases where contracting parties cannot rely upon social ties. We ask if a community can...
