We investigate the degree of financial integration within and between European countries. We construct two measures of de-facto integration across European regions to capture "diversification" and "development" finance in the language of Obstfeld and Taylor (2004). We find evidence that capital market integration within the EU is less than what is implied by theoretical benchmarks and also less than what is found for U.S. states. We ask - why is this the case? Using country-level data for economic institutions, we find that these are not able to explain differences between countries. Using regional data from the World Values Surveys, we investigate the effect of "social capital" on financial integration among European regions. We find regions, where the level of confidence and trust is hig...

The magnitude and the direction of net international capital flows does not fit neo-classical models. The 50 U.S. states comprise an integrated capital market with very low barriers to capital flows, which makes them an ideal testing ground for neoclassical models. We develop a simple frictionless open economy model with perfectly diversified ownership of capital and find that capital flows between the U.S. states are consistent with the model. Therefore, the small size and "wrong" direction of net international capital flows are likely due to frictions associated with national borders and not due to inherent flaws in the neoclassical model.

We measure the amount of smoothing achieved through various components of the government deficit in EU and OECD countries. For EU countries, at the 1-year frequency percent of shocks to GDP are smoothed via government consumption, 18 percent via transfers percent via subsidies, while taxes provide no smoothing. The results for OECD countries are similar. Government transfers provide more smoothing of negative than of positive shocks among EU countries. There seems to be no trade-off between high government deficits in a country and the ability to smooth consumption. We find that in countries where there is delegation' of power or where fiscal targets are negotiated effectively by coalition members consumption smoothing via government consumption and government transfers is considerabl...
