What determines structure and profitability across markets for goods and services? Understanding the relationship between market structure and performance is critical for determining effective economic policy governing anti-trust, intellectual property, industry regulation, and international...

This paper investigates the market structure of the Greek food and beverages manufacturing industry over the period 1984–2007 at the three-digit SIC level. Based on the Hall-Roeger approach (1995), three models are used to investigate the competitive conditions in the industry. The first model...

How should complementarities affect antitrust merger policy? I introduce a two-stage strategic model in which complementary input sellers offer supply schedules to producers and then engage in bilateral bargaining with producers. The main result is that there is a unique weakly dominant strategy...

I introduce a reduced form two-sided market model to study prediction and identification in two-sided markets. The model generates the hallmark features of two-sided markets: potentially below cost or even negative prices to one side of the market, and the “see-saw” or “waterbed” effect...

This Handbook chapter seeks to introduce students and researchers of industrial organization (IO) to the field of market design. We emphasize two important points of connection between the IO and market design fields: a focus on market failures—both understanding sources of market failure and...
