We develop a model of repeated product improvements in a continuum of sectors. Each product follows a stochastic progression up a quality ladder. Progress is not uniform across sectors, so an equilibrium distribution of qualities evolves over time. But the rate of aggregate growth is constant....

We analyze entry, pricing and product design in a model with differentiated products. Under plausible conditions, entry into an initially monopolized market leads to higher prices for some, possibly all, consumers. Entry can induce a misallocation of goods to consumers, segment the market in a...

Thereare three points made in this paper. The first is that the question concerning choice of a product line by a monopolist is similar in structure to other adverse selection problems -- and can be analyzed in an elementary way by adapting techniques recently developed for such problems. Such...

Product redesigns happen across virtually all types of products. While there is substantial evidence that new varieties of goods increase welfare, there is little evidence on the effect of product redesigns. We develop a model of redesign and exit decisions in a dynamic oligopoly model (a la...

DuPont, one of the most respectable U.S. companies, caused environmental damage that ended up costing the company around a billion dollars. By using internal company documents disclosed in trials we rule out the possibilities that this bad outcome was due to ignorance, an unexpected realization,...

This paper explores the links between exports, export destinations and skill utilization by firms. We identify two mechanisms behind these links, which we integrate into a unified theory of export destinations and skills. First, exporting to high-income countries with higher valuation for...

Prior work has established that the financing environment can impact firm strategy. We argue that this influence can shape the earliest strategic choices of a new venture by creating a potential tradeoff between two objectives: rapid growth and reaping the benefits of a positive reputation...

The appropriability of innovation depends not only on the instruments available to an innovator to protect private returns, but how those instruments interact with each other as part of the firm's entrepreneurial strategy. We consider the interplay between two appropriability mechanisms...

This is an attempt to derive broad, strategic lessons from the diverse experience with economic growth in last fifty years. The paper revolves around two key arguments. One is that neoclassical economic analysis is a lot more flexible than its practitioners in the policy domain have generally...

This paper draws on a detailed history of Intel's strategy with respect to the complementary markets for microprocessors to explore the usefulness of the current theoretical literature for explaining behavior. We find that as the literature predicts, Intel invests heavily in these markets, both...
