Abstract
This paper examines the effects of antitrust enforcement on local economic activity. Using newly collected data on the operation of the Department of Justice Antitrust Division’s local field offices, we document that increased federal antitrust enforcement leads to higher employment, more new businesses, and higher earnings. We find that the effects are driven by smaller and younger firms, and by areas with higher levels of initial concentration. The effects appear in tradable and non-tradable sectors, and are not driven by federal contracts or defense spending. The results suggest that antitrust enforcement plays an important role in promoting local economic activity.
