This paper estimates a dynamic, structural model of entry and exit in an oligopolistic industry and uses it to quantify the determinants of market structure and long-run firm values for two U.S. service industries, dentists and chiropractors. Entry costs faced by potential entrants, fixed costs...

We study the evolution of imitation behaviour in a differentiated market where firms are located equidistantly on a Salop circle. Firms choose price and quantity simultaneously, leaving open the possibility for non-market clearing outcomes. The strategy of the most successful firm is imitated....

We investigate a multi-market Cournot model with strategic process research and development (R&D) investments wherein a multi-market firm meets new competitors that enter one of the markets. We show that entry can enhance the total R&D expenditures of the multi-market firm. Moreover, the...

Prior research shows that grocery stores reduce prices to compete with Walmart Supercenters. This study finds evidence that the competitive effects of two other big-box retailers—Costco and Walmart-owned Sam's Club—are quite different. Using city-level panel grocery price data matched with a...

We study the effects of cooperative wage setting in industries that use two different types of labor. In particular, we consider a two-stage game where firms hire non-specialized workers in a perfectly competitive labor market and specialized workers that are more productive and expensive, but...

This paper investigates the degree of competition in the WAEMU financial industry over the period 2002-2007 using firm-level data (591 year-firm observations). Market structure analysis, the Panzar-Rosse model and conjectural variation are applied to assess the level of competition. The results...

In a two-country general oligopolistic equilibrium model, I study how cross-sector strategic trade policy affects wages, countrywide profits, and welfare. Firms face resource constraints and wages are simultaneously determined. Relative to free trade, cross-sector protectionism generates a...

We report the results of duopoly market experiments where firms first commit to capacities and then compete in prices. The theoretical literature pertaining to these duopoly models suggests that the way residual demand is rationed is fundamental to the character of equilibrium outcomes when...

Horizontal mergers are usually under the scrutiny of antitrust authorities due to their potential undesirable effects on prices and consumer surplus. Ex-post evidence, however, suggests that not always these effects take place and even relevant mergers may end up having negligible price effects....

This paper investigates the relationship between technical efficiency and industrial concentration in the Indonesian food and beverages sector. Firm-level data obtained from the Indonesian Bureau of Central Statistics (BPS) are used to estimate technical efficiency scores and calculate measures...
