Globalization has affected business cycle developments in OECD countries and has increased activities of firms across national borders. This paper analyzes whether these two developments are linked. We use a new firm-level dataset on the foreign activities of German firms to test whether foreign...

In the context of energy security and climate protection, biomass is given high importance. Nevertheless, land-use conflicts resulting from the cultivation of biomass and their economy-wide effects are yet to be fully understood. To shed light on this issue we link three distinctive models; a...

This paper sheds light on how changes in the organization of work lead to wage inequality. We present a theoretical model in which workers with a wider span of competence (higher level of multitasking) earn a wage premium. Since abilities and opportunities to expand the span of competence are...

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...

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...

The paper analyzes the influence of minimum wages on firms' incentive to train their employees. We show that this influence rests on two countervailing effects: minimum wages (i) augment wage compression and thereby raise firms' incentives to train and (ii) reduce the profitability of employees,...

We explore the far-reaching implications of low-wage subsidies on aggregate employment. Low-wage subsidies have three important effects. First, they promote employment of unskilled workers (who tend to be the ones who earn low wages). Second, by raising the payoff of unskilled work relative to...

The paper concentrates on the question whether the low level of productivity in East Germany can be explained by deficits in the stock of human capital. It is shown that figures on formalʺ qualifications yield a too optimistic view on human capital endowments; in fact, the effective stock on...

This paper analyses how and to which degree the Danish flexicurity concept and its various elements achieve the renowned Danish miracle by evaluating their unemployment and inequality effects and their complementarities. We develop a microfounded model of searching workers and firms, calibrate...
