This paper analyses the wage premia associated with workers' occupational use of foreign languages in Germany. After eliminating time-invariant unobserved heterogeneity and other confounding factors, sizable returns of about 10 percent to applying fluent English skills are found. Returns to...

This paper compares two prominent empirical measures of individual risk attitudes — the Holt and Laury (2002) lottery-choice task and the multi-item questionnaire advocated by Dohmen, Falk, Huffman, Schupp, Sunde and Wagner (2011) — with respect to (a) their within-subject stability over...

The Fukushima Daiichi accident in Japan in March 2011 caused a fundamental change in Germany's energy policy which led to the immediate shut down of nearly half of its nuclear power plants. This paper uses data from Germany's largest internet platform for real estate to investigate the effect of...

We investigate the impact of offshoring on individual level wages and unemployment probabilities and pay particular attention to the question of whether workers on temporary contracts are affected differently than workers on permanent contracts. Data are taken from the German Socio-Economic...

This paper analyzes the effects of short-time work (i.e., government subsidized working time reductions) on unemployment and output fluctuations. The central question is whether the rule based component (i.e., the existence of the institution short-time work) and the discretionary component...

We develop a comprehensive wealth index for cities that measures their endowment with environmental, energy, social, human, and economic capital stocks. We apply this index to the 100 largest autonomous cities in Germany. We find that (i) a good economic performance does not need to come at the...

Development assistance has been criticized for a lack of coordination between aid donors. This paper argues that competition for export markets and political support prevents donor countries from closer coordination of aid activities. To test these hypotheses, we perform logit and fractional...

We describe the determinants of energy intensity, carbon intensity, and CO2 emissions in the German manufacturing sector between 1995 and 2007, applying the LMDI index decomposition technique not to aggregate but to micro data. We trace back changes in total CO2 emissions from manufacturing to...

We investigate the importance of geo-strategic and commercial motives for the allocation of German aid to 138 countries over the 1973-2010 period. We find that geo-strategic and – less robustly – commercial motives matter. When we relate geo-strategic and commercial motives to the political...

This paper reveals that German firms with working time accounts (WTAs) show a similar separation and hiring behavior in response to revenue changes as firms without WTAs. This finding casts doubt on the popular hypothesis that WTAs were the key driver of the unusually small increase in German...
