By combining two large data sets (on international trade flows and on mergers and acquisitions - M&As), we are able to test two implications of Neary's (2003, 2004a) recent theoretical work. Analyzing M&As in a General Oligopolistic Equilibrium (GOLE) model incorporating strategic interaction...

The median cartel had five corporate members and generated $1.2 billion in sales during the collusive period. Nearly 40% of affected sales occurred in the...
