The events of Sept. 11, 2001, prompted sweeping cross-border coordination efforts for securities regulators around the globe. After 9/11, the International Organization of Securities Commissions (IOSCO) forged a nonbinding arrangement — the Multilateral Memorandum of Understanding Concerning Consultation and Cooperation and the Exchange of Information (MMoU) — that standardized the protocol for information sharing among participating securities regulators. Because regulators from different countries entered the MMoU at different times, their enlistments created a set of staggered shocks. I use these shocks to show that the resulting cross-border cooperation (a) increases cross-border enforcement and (b) reduces the cost of liquidity provision in the capital markets. These results support the idea that the MMoU helps fill gaps in cross-border regulation that historically exposed investors to information asymmetry, agency costs, and expropriation risks.
