Abstract
We investigate credit risk co-movements and contagion in sovereign debt markets of 17 industrialized countries for the period 2008-2012. We use dynamic conditional correlations of sovereign CDS spreads to detect contagion. This approach allows separating the channels through which contagion occurs from the determinants of simple interdependence. The results show that, first, sovereign credit risk comoves considerably, in particular among eurozone countries and during the sovereign debt crisis. Second, contagion cannot be attributed to one moment in time but varies across time and countries. Third, similarities in economic fundamentals, cross-country linkages in banking, and common market sentiment constitute the main channels of contagion.

Abstract
We analyze the decline in the U.S. share of world merchandise exports against the backdrop of a model-based measure of competitiveness. We preliminarily use constant market share analysis and gravity estimations to show that the majority of the decline in export shares can be associated with a declining share of world income, suggesting that the dismal performance of the U.S. market share is not a sufficient statistic for competitiveness. We then derive a computable measure of country-sector specific real marginal costs (i.e. competitiveness) which, insofar it is inferred from actual trade ows, is referred to as 'revealed'. Brought to the data, this measure reveals that most U.S. manufacturing industries are losing momentum relative to their main competitors, as we find U.S. revealed marginal costs to grow by more than 38% on average. At the sectoral level, the "Machinery" industry is the most critical.

Abstract
In the aftermath of re-unification, East German exports declined around 70% due to the breakdown of COMECON trade. Although since the mid-1990s export growth rates of the New Federal States were higher than those of their West German counterparts, export performance of East German States measured by the share of exports in GDP is still comparatively poor. Whereas for a long time the low export performance of East German producers was ascribed to competitive disadvantages, in the meantime structural deficits on the micro and/or macro level are often considered as the main reason. Using bilateral trade data of German Federal States, the present paper shows on the basis of an orthodox gravity model of trade that East German exports are explicitly lower than predicted by the model. But if the gravity model is augmented by additional variables representing structural differences between Federal States, the latter explain almost entirely the lower export performance of Eastern Germany. Thus, especially the smaller firm sizes and the lower shares of manufacturing industries in gross value added are identified as important explanatory factors of the comparatively weak export performance of the New German States.
