We analyze the location of stock trading for firms with a US cross-listing. The fraction of trading that occurs in the United States tends to be larger for companies from countries that are geographically close to the United States and feature low financial development and poor insider trading protection. For companies based in developed countries, trading volume in the United States is larger if the company is small, volatile, and technology-oriented, while this does not apply to emerging country firms. The domestic turnover rate increases in the cross-listing year and remains higher for firms based in developed markets, but not for emerging market firms. Domestic trading volume actually declines for companies from countries with poor enforcement of insider trading regulation

[As the number of bank failures increases, the set of assets available for acquisition by surviving banks enlarges but the total liquidity available with surviving banks falls. This results in "cash-in-the-market" pricing for liquidation of banking assets. At a sufficiently large number of bank failures, and in turn, at a sufficiently low level of asset prices, there are too many banks to liquidate and inefficient users of assets who are liquidity-endowed may end up owning the liquidated assets. In order to avoid this allocation inefficiency, it may be ex-post optimal for the regulator to bail out some failed banks. We show, however, that there exists a policy that involves granting liquidity to surviving banks in the purchase of failed banks, which is equivalent to the bailout policy from an ex-post standpoint. Crucially, this liquidity provision policy gives banks incentives to differentiate, rather than to herd, makes aggregate banking crises less likely, and thereby dominates the bailout policy from an ex-ante standpoint
