Most regulators around the world reacted to the 2007-09 crisis by imposing bans or constraints on short-selling. These were imposed and lifted at different dates in different countries, often applied to different sets of stocks and featured varying degrees of stringency. We exploit this variation in short-sales regimes to identify their effects on liquidity, price discovery and stock prices. Using panel and matching techniques, we find that bans (i) were detrimental for liquidity, especially for stocks with small capitalization and no listed options; (ii) slowed down price discovery, especially in bear markets, and (iii) failed to support prices, except possibly for U.S. financial stocks.
