Collective Action and the Origins of the American Labor Movement

Abstract

This article examines the relationship between collective action and the size of worker and employer groups in the United States. It proposes and tests a theory of union formation and strikes. Using a new county-by-industry level dataset containing the location of unions, the location of strikes, average establishment size, and the number of establishments around the turn of the twentieth century, I find that unions were more likely to form and strikes were more likely to occur in counties with intermediate-sized worker groups and large employer groups.
