Introduction: the dynamics of industrial organization

This paper introduces the special issue of The Review of Industrial Organization on The Dynamics of Industrial Organization. What binds these papers together is a focus on markets in motion—the process by which new firms enter an industry, either grow and survive, or else ultimately exit out of the industry. In contrast to more traditional static analyses, the concern of these papers is identifying where do firms come from and what happens subsequent to their entry. Influences of geographic as well as product space are found to exert an influence on the dynamics of industrial organization.
