We study the cyclical behavior of antitrust enforcement as measured by the number of cases initiated by the US Department of Justice. The key result is that antitrust case activity is countercyclical. This finding is robust across alternate indicators of economic activity which include stock...

The United States stood virtually alone when it enacted its first antitrust statute in 1890. Today, almost all nations have adopted competition laws (the term used in most other nations), and US antitrust agencies interact with foreign enforc-ers on a daily basis.
