This paper examines the role of hierarchies in the organization of human‐capital‐intensive production. We develop an equilibrium model of hierarchical organization and provide empirical evidence based on confidential data on thousands of law offices. The equilibrium assignment of individuals...

Explaining patterns of asset ownership in the economy is a central goal of both organizational economics and industrial organization. We develop a model of asset ownership in trucking, which we test by examining how the adoption of different classes of on-board computers (OBCs) between 1987 and...

Empirical research on the determinants of firms' boundaries has flourished over the past 25 years. This article discusses the progress that has been made to date, emphasizing the intellectual advances made by researchers in this literature during this period. I stress empirical researchers'...

This paper presents theory and evidence on horizontal industry structure, focusing on situations where plant-level scale economies are small and market power is not an issue. At issue is the question: what makes industries necessarily fragmented? The theoretical model distinguishes between the...

Productivity reflects not only how efficiently inputs are transformed into outputs, but also how well information is brought to bear on resource allocation decisions. This paper examines this empirically by looking at how on-board computer (OBC) adoption has affected capacity utilization in the...

Moral hazard exists in diagnosis-cure' markets because sellers have an incentive to" shade their reports of buyers' condition to increase the short-run demand for the treatments they" supply. The California vehicle emission inspection market offers a rare opportunity to examine" how incentives...

How far do the contractual implications of hold-up-based theories (Klein, Crawford, and Alchian (1978), Williamson (1979, 1985)) extend? I investigate this in the context of trucking. Quasi-rents in trucking are generally smaller than in the contexts studied in the previous empirical literature....

This article uses confidential microdata from the Census of Services to examine law firms' field boundaries. We find that the share of lawyers working in field-specialized firms increases as market size increases and lawyers field specialize, indicating that transaction costs among lawyers, and...

Most empirical work in the economics of organization consists of theory-testing exercises, where the theories under examination rely on optimality principles but not equilibrium. This paper discusses recent attempts to bring equilibrium analysis into the economics of organization, highlighting...
