This paper observes that short-selling bans spread globally beginning in 2007. The authors seek to empirically determine whether there were spillover effects over and above the domestic impact from the imposition of such bans. There is some evidence that the bans were unsuccessful, at least insofar as they did not take into account the global component a short-selling ban might have. In the individual countries they examine, the bans had relatively little impact. Nevertheless, the paper’s finding that equity returns do not appear to show a decline may be evidence that the bans stemmed further deterioration in stock prices that policy makers sought to avoid.
