We estimate the effects of deregulation of U.S. banking restrictions on interstate personal income insurance for the period 1970 to 2001. Interstate income insurance occurs when personal income reacts less than one-to-one to state-specific output shocks. We find that insurance improved after banking deregulation, with a larger effect in states where small businesses are more important and on proprietors' income than on other components of personal income. Our explanation centers on the role of banks as a prime source of small business finance and on the close intertwining of the personal and business finances of small business owners.

This paper documents that stock liquidity improves shareholders' incentive to monitor management. Using a hand-collected sample of contested proxy solicitations and shareholder proposals as occurrences of shareholder activism, we find that poor firm performance increases the probability of shareholder activism and that this relationship is much stronger for firms with liquid stock than for other firms. The conclusion that liquidity improves monitoring is robust to different measures of firm performance and liquidity. We also document that target shareholders earn positive abnormal returns on the announcement date of activism and conclude that shareholder activism creates shareholder value.

This paper investigates whether risk sharing, measured as income and consumption smoothing, among countries in the EU and the European Economic and Monetary Union (EMU) has increased since the adoption of the euro. We ask: Have the recent increase in foreign equity and debt holdings been associated with more risk sharing? Do certain classes of assets (debt, equity, foreign direct investment) provide relatively more or less risk sharing? Do liabilities provide risk sharing differently from assets? Do investments in EMU countries provide more or less risk sharing per euro invested compared to investments in non-EMU countries? Has increased banking integration improved risk sharing? Due to the short span of years since the introduction of the euro, our results are tentative, but they indicate that the monetary union has facilitated risk sharing, although the level of risk sharing is still much below the level found among U.S. states. * This study was conducted with financial support from the European Commission, contract ECFIN/263/2007/477567.

The views expressed herein are solely those of the authors and do not necessarily reflect the views of Norges Bank, the Federal Reserve Bank of St. Louis or the Federal Reserve System.Overall, our results leave little doubt that the process of financial integration among EMU countries has been associated with beneficial welfare effects, in particular in the form of improved smoothing of income. Financial integration, however, is progressing only slowly and the overall level of integration is still lagging behind the level of integration between U.S. states where cross-state investment and securities holdings are much more pervasive.

We compute optimally diversified international asset portfolios for banks located in France, Germany, Italy, the United Kingdom and the United States using the mean-variance portfolio model with currency hedging. We compare these benchmark portfolios with the actual cross-border asset positions of banks from 1995 to 2003 and ask whether the differences are best explained by regulations, institutions, cultural conditions or other financial frictions. Our results suggest that both culture and regulations affect the probability of a country's being overweighted in à We thank two anonymous referees and the editor (Benn Steil) for helpful comments and suggestions that improved the paper.
