The Cyclical upswing in Germany continues, in spite of foreign demand losing momentum
In autumn 2018, the global economy continues to expand quite strongly. Whereas the cyclical upswing in the USA has gained even more strength, the economy in the Euro area has weakened somewhat. To a lesser extent, this also applies to the German economy. “According to this forecast, the growth rate of German real gross domestic product will be 1.8% in 2018 and 1.7% in 2019. The East German economy will expand by 1.5% this year and by 1.4% in 2019”, says Oliver Holtemöller, head of the Department Macroeconomics and vice president at IWH.

Migration Affects Labour Market in Eastern Germany
Migration increasingly affects the labour market in Eastern Germany, having effects on employment and unemployment figures as well as the number of recipients of social assistance benefits under the SGB II regulations. Particularly with countries in Middle and Eastern Europe, countries affected by the European debt and confidence crisis and with people seeking asylum, there are large increases meeting the dimensions in Western Germany. However, migrants overall still form a significantly smaller percentage of the population and other labour market parameters in Eastern Germany, since migration was a lot stronger in Western Germany during the last decades. While on the short run negative effects on unemployment have to be expected, there are also chances, in the medium- and long-term, to soften the expectable demographic problems, if integration and qualification are supported.

Estimation Uncertainty in Credit Risk Assessment: Comparison of Credit Risk Using Bootstrapping and an Asymptotic Approach
IWH Discussion Papers,
For credit risk assessment, probability of default and correlation have to be estimated simultaneously. However, these estimates are uncertain. To assess this uncertainty the literature has discussed the use of asymptotic confidence regions. This kind of region though needs a long credit history for exact assessment. An alternative method to generate a confidence region for a short credit history is bootstrapping. Hence, it could be more appropriate to assess estimation uncertainty with bootstrapping than with asymptotic methods if only a short credit history is available. Based on a simulation study, it is analyzed how many periods should be available for assessing credit risk – taking account of estimation uncertainty – if bootstrapping and a Wald confidence region shall achieve similar results. This article shows that more than 100 cycles have to be available for similar results.
