This paper revisited the analytics of the welfare significance of market imperfections using the industry concentration index. It reopened the issue of how best to measure the concentration index. Specifically, it developed a new market concentration index based on the Hirschman- Herfindahl...

We explore the logic of predation and rules designed to prevent it in markets subject to network effects. Although, as many have informally argued, predatory behavior is plausibly more likely to succeed in such markets, we find that it is particularly hard to intervene in network markets in ways...

e use a Hotelling linear city model to study competition between open source and proprietary software, where only the producer of the proprietary software aims at maximizing the profit. The producer of the proprietary software must decide on compatibility. Different compatibility strategies will...

We consider a standard model of consumer switching costs with demand uncertainty where firms observe private information about demand. Given this private information, each firm forms beliefs over different demand realizations as well as beliefs over the other firm's information. The main result...

This study uses an agent-based computational labor market framework to experimentally study the relationship between job capacity, job concentration, and market power. Job capacity is measured by the ratio of potential job openings to potential work offers, and job concentration is measured by...

This study undertakes a systematic experimental investigation of hysteresis (path dependency) in an agent-based computational labor market framework. It is shown that capacity asymmetries between work suppliers and employers can result in two distinct hysteresis effects, network and behavioral,...

The paper examines the economic and regulatory factors that led to an explosion in the wholesale power prices, supply shortages, and utility insolvencies in California’s electricity sector. A necessary first step in determining the lessons learned from the California electricity crisis is a...

We use a Hotelling linear city model to study competition between open source and proprietary software, where only the producer of the proprietary software aims at maximizing the profit. The producer of the proprietary software must decide on compatibility. Different compatibility strategies...

This paper presents an equilibrium model of industry dynamics and capital structure decisions. The unique stationary equilibrium is derived in closed-form. The analysis reveals that the interaction between capital structure and production decisions influences the stationary distribution of...

DOMESTIC MARKETS AND INTERNATIONAL COMPETITIVENESS This paper develops a theoretical and empirical model to analyze the effects of the size and nature of domestic markets on the international competitiveness of national industries. We validate our theory using data on the more than 20,000 plants...
