Kombilöhne gegen Erwerbsarmut: Warum die USA erfolgreicher sind als Deutschland

“Make work pay” strategies are an integral part of labour market policy instruments in developed countries. There are two considerations behind these measures. Firstly, subsidizing employment at the bottom of the income distribution should motivate the unemployed to accept jobs with lower market wages. Secondly, the wage supplement should increase the living standards of the recipients and reduce the risk of poverty. The U.S. EITC and the German UB II based on these two goals. Our paper begins with an overview of these two wage top-up schemes. This is followed by an empirical evaluation of the two instruments regarding their capacity to prevent in-work poverty and to strengthen labour market participation. The EITC obtains better results compared to UB II in both regards.     

Die Entwicklung der HSH Nordbank als Landesbank — einige Einschätzungen

Some of the German “Landesbanken” engaged in highly risky business with the acceptance of local politicians and then demanded bailouts during the financial crisis. The HSH Nordbank, the world’s largest provider of ship financing, based in northern Germany, lost almost 2.8 billion euros in 2008. The two German shareholders, the states of Hamburg and Schleswig-Holstein, had to agree on a 13 billion euro bailout plan for the bank (3 billion euros in cash and a “risk shield” of 10 billion euros). Furthermore, the German government provided the HSH Nordbank with 17 billion euros of liquidity guarantees under the Special Financial Market Stabilisation Fund (SOFFIN). In view of this situation, the following questions should be answered: What role did the merger of the Hamburger Landesbank and Landesbank Schleswig-Holstein play in the development of the HSH Nordbank? Was there a possibility to merge the HSH Nordbank with another bank to avoid the financial difficulties? Were the extensive conditions set by the EU Commission in the state aid proceedings too restrictive? What are the actual costs of the HSH Nordbank’s bailout programme for the shareholders and their governmental budgets?

Einkommens- und Vermögensverteilung — zu ungleich?

The distribution of income and wealth in Germany grew increasingly unequal until the beginning of the financial crisis. But inequality has not risen in either Germany or Switzerland since 2005. Nevertheless, Germans overestimate inequality. The German gap between reality and perception of inequality is important to investigate, as the subjective assessment of inequality influences redistribution preferences. Rising inequality may damage social stability and democracy, but it is unclear whether economists are able to assess a “proper and just” distribution. Interdependencies are discussed: Does a more equal distribution create negative effects on economic growth? How does Germany rank internationally with regard to distribution? Social mobility rates differ substantially across countries; what are the implications for economic policy?     

A logic system for the choice of risk levels in hypothesis testing

We have examined current, traditional practice of establishing risk levels, favoring use of small α and implicitly accepting correspondingly larger β errors. There are both loses and gains associated with this approach. In particular, small a minimizes the probability of erroneously rejecting H_o, but it also increases the chances that a new model, representing a real improvement, may be discarded. There is no overwhelming logic that one type of error is always more important than the other, since relative costs vary with the conditions surrounding the research investigation.
