Commonly used methods of production function estimation assume that a firm’s output quantity can be observed as data, but typical datasets contain only revenue, not output quantity. We examine the nonparametric identification of production function from revenue data when a firm faces a general...

The idea of an industrial policy that promotes large businesses - heavyweights - as the best way to compete in a globalized world has become, again, en vogue among European politicians. The only apparent controversy about the idea revolves around whether it is better to promote national...

Business climate indicators are used to receive early signals for turning points in the general business cycle. Therefore methods for the detection of turning points in time series are required. Estimations of slopes of a smooth component in the data can be calculated with local polynomial...

Workers wrongly anchor their beliefs about outside options on their current wage. In particular, low-paid workers underestimate wages elsewhere. We document this anchoring bias by eliciting workers’ beliefs in a representative survey in Germany and comparing them to measures of actual outside...

We measure individual bias in labor market expectations in German survey data and find that workers on average significantly overestimate their individual probabilities to separate from their job when employed as well to find a job when unemployed. These biases vary significantly between...

This paper studies the market and welfare effects of income heterogeneity in monopolistically competitive product markets in the context of nonhomothetic preferences. In a closed economy, where richer individuals’ expenditures are less sensitive to price change compared to poorer ones’, a...

The compensation of executive board members in Germany has become a highly controversial topic since Vodafone's hostile takeover of Mannesmann in 2000 and it is again in the spotlight since the outbreak of the financial crisis of 2009. Based on unique panel data evidence of the 500 largest firms...

The path breaking work of Card and Krueger (1993), showing higher minimum wage can increase employment turned the age-old conventional wisdom on its head. This paper demonstrates that this apparently paradoxical result is perfectly plausible in a competitive general equilibrium production...

The German law on co-determination at the plant level (Betriebsverfassungsgesetz) stipulates that works councilors are neither to be financially rewarded nor penalized for their activities. This regulation contrasts with publicized instances of excessive payments. The divergence has sparked a...

We develop a dynamic spatial model in which heterogeneous workers are imperfectly mobile and forward-looking and yet all structural fundamentals can be inverted without assuming that the economy is in a stationary spatial equilibrium. Exploiting this novel feature of the model, we show that the...
