Many founding teams of new firms form at a common employer. We model team formation and the entry of employee spinoffs by extending the Jovanovic (1979) theory of job matching and employer learning. In our social-capital model employees learn about their colleagues' characteristics at a faster...

Recently collected data show that, within any manufacturing industry, vertically integrated firms tend to have larger, higher productivity plants, account for the bulk of sales, and also sell externally most of the inputs they produce. In a weak contracting environment characteristic of...

One of the leading theories of entrepreneurship is that less risk averse individuals become entrepreneurs and more risk averse individuals become their employees. Kihlstrom and Laffont (1979) formalized this insight in an elegant and widely taught general equilibrium model. However, their model...

Empirical studies have consistently found that skilled-labor abundant countries tend to export skilled-labor intensive manufactured goods. Yet these countries also have higher wages for skilled workers, causing them to be net importers through migration of skilled labor from unskilled-labor...

When trade involves differentiated products, preferential ties to a group settled abroad facilitate an exporter's entry into the foreign market by providing information and access to distribution channels. This contrasts with the difficulties experienced by an unattached producer unfamiliar with...

Some cultural goods, like clothes and films, are consumed socially and are thus characterized by the same consumption network externalities as languages. At the same time, producers of new cultural goods in any one country draw on the stock of ideas generated by previous cultural production in...

Using a comprehensive linked employer-employee database from Brazil for the period 1995-2001, we are able for the first time to compare firms founded as employee spinoffs to new firms without parents and to diversification ventures of existing firms entering a new industry. Employee spinoffs are...

What determines the boundary of multinational firms? According to Williamson (1975), a potential rationale for vertical integration is to facilitate adaptation in a world where uncertainty is resolved over time. This paper offers the first empirical analysis of the impact of adaptation on the...

A functional relationship between the degree of a country?s comparative advantage in any good and the volume of its net exports of that good to its trading partner is established using a model with per-unit-distance transportation costs between countries' coasts and their interiors. The greater...

The evolution of inequality in permanent income is investigated during the course of a less developed country's transformation from a primarily agricultural to a primarily urban-industrial economy. The source of inequality is market luck in obtaining employment in the protected urban "formal...
