While much research in political economy points out the benefits of ''limited government,'' political scientists have long emphasized the problems created in many less-developed nations by ''weak states,'' which lack the power to tax and regulate the economy and to withstand the political and social challenges from non-state actors. I construct a model in(More)

This paper extends parts of the results from [17] for plane curves to the case of hypersurfaces in R n. Let M be a compact connected oriented n − 1 dimensional manifold without boundary like S 2 or the torus S 1 × S 1. Then shape space is either the manifold of submanifolds of R n of type M , or the orbifold of immersions from M to R n modulo the group of(More)
We study Sobolev-type metrics of fractional order on the group of compactly supported diffeomorphisms Diffc(M), where M is a Riemannian manifold of bounded geometry. We prove that the geodesic distance, induced by the Riemannian metric, vanishes if the order s satisfies 0 ≤ s < 1 2. For M = R we show the vanishing of the geodesic distance also for s = 1 2 ,(More)
Let M be a compact connected oriented n−1 dimensional manifold without boundary. In this work, shape space is the orbifold of unparametrized immersions from M to R n. The results of [1], where mean curvature weighted metrics were studied, suggest to incorporate Gauß curvature weights in the definition of the metric. This leads us to study metrics on shape(More)
We investigate the relationship between financial integration and output volatility at micro and macro levels. Using a very large firm-level dataset from EU countries over time, we construct a measure of " deep " financial integration at the regional level based on foreign ownership at the firm level. We find a positive effect of foreign ownership on(More)
The Policy Research Working Paper Series disseminates the findings of work in progress to encourage the exchange of ideas about development issues. An objective of the series is to get the findings out quickly, even if the presentations are less than fully polished. The papers carry the names of the authors and should be cited accordingly. The findings,(More)
