This paper uses confidential microdata from the Census of Services to examine lawfirms' field boundaries. We find that the share of lawyers working in field-specializedfirms increases as market size increases and lawyers field-specialize, indicating thattransaction costs among lawyers, and not...

This paper examines hierarchies’ role in the organization of human-capital-intensive productionWe develop an equilibrium model of hierarchical organization, then provide empirical evidenceusing confidential data on thousands of law offices from the 1992 Census of Services. We showhow the...

A large theoretical literature focuses on the question: What determines firms’ boundaries?Recently, Garicano and Santos and Holmstrom and Milgrom have proposed theories in whichfirms’ boundaries reflect the division of labor across individuals. This paper discussesstrategies for generating...

This paper exploits empirically a key insight from Lucas (1978) and Rosen (1982): that the organization of production and the distribution of earnings across individuals are jointly determined by the equilibrium assignment of individuals to firms and hierarchical positions. We study how...

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...

Earnings inequality has increased substantially since the 1970s. Using evidence changes from con…dential Census data on U.S. law offices on lawyers'organization and earnings, we study the extent to which the mechanism suggested by Lucas (1978) and Rosen (1982), a scale of operations effect...

Hierarchies allow individuals to leverage their knowledge through others' time. This mechanism increases productivity and amplifies the impact of skill heterogeneity on earnings inequality. To quantify this effect, we analyze the earnings and organization of U.S. lawyers and use the equilibrium...

What role do hierarchies play with respect to the organization of production and what determines their structure? We develop an equilibrium model of hierarchical organization, then provide empirical evidence using confidential data on thousands of law offices from the 1992 Census of Services....

What is the role of firms and markets in mediating the division of labor? This paper uses confidential microdata from the Census of Services to examine law firms' boundaries. We find that firms' field scope narrows as market size increases and individuals specialize, indicating that firms'...
