The following post comes to us from Marco Ventoruzzo of Pennsylvania State University, Dickinson School of Law, and Bocconi University.
In the European Union insider trading has been regulated much more recently than in the United States, and it can be argued that, at least traditionally, it has been more aggressively and successfully enforced in the United States than in the European Union. Several different explanations have been offered for this difference in enforcement attitudes, focusing in particular on resources of regulators devoted to contrasting this practice, but also diverging cultural attitudes toward insiders. This situation has evolved, however, and the prohibition of insider trading has gained traction also in Europe. Few studies have focused on the substantive differences in the regulation of the phenomenon on the two sides of the Atlantic.
