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...

We provide a new model that generates persistent performance differences amongst seemingly similar enterprises. Our model provides a mechanism whereby efficient incumbent rivals can give permission for an inefficient firm to exist in the presence of efficient entrants. We demonstrate that, in a...

We provide a model and empirical tests showing how an active acquisition market affects firm incentives to innovate and conduct R&D. Our model shows that small firms optimally may decide to innovate more when they can sell out to larger firms. Large firms may find it disadvantageous to engage in...

We propose a theory of firm dynamics in which workers have ideas for new projects that can be sold in a market to existing firms or implemented in new firms: spin-offs. Workers have private information about the quality of their ideas. Because of an adverse selection problem, workers can sell...

Most government expenditure is on goods that yield primarily private benefits, such as education, pensions, and healthcare. We argue that markets are most advantageous in areas where high-powered incentives are desirable, but in areas where high-powered incentives stimulate unproductive...

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 paper develops the idea that when markets are imperfectly competitive, final producers may gain from a joint venture that produces part of their input requirements even though marginal cost exceeds the input's market price. Production by the joint venture lowers the market price of the...

There exist two approaches in the literature concerning the multinational firm's mode choice for foreign production between an owned subsidiary and a licensing contract. One approach considers environments where the firm is transferring primarily knowledge-based assets. An important assumption...

We consider a bilateral trading problem in which one or both parties makes relationship-specific investments before trade. Without adequate contractual protection, the prospect of later holdups discourages investment. We postulate that the parties can sign noncontingent contracts prior to...

We study how firms differ from their competitors using new time-varying measures of product differentiation based on text-based analysis of product descriptions from 50,673 firm 10-K statements filed yearly with the Securities and Exchange Commission. This year-by-year set of product...
