In 2015, Germany introduced a national minimum wage. While the literature agrees on at most limited negative effects on the overall employment level, we go into detail and analyze the impact on the working hours dimension and on the subset of minijobs. Using data from the German Structure of...

This paper investigates the effects of the introduction of a statutory minimum wage in Germany on the wages and employment of migrants. Migrants are an overrepresented group in the low-wage sector and can be expected to particularly benefit from a minimum wage. We combine a "differential trend...

This paper studies the relationship between occupational employment, occupational wages, and rising wage inequality. We document that in all occupations, entrants and leavers earn less than stayers. This suggests selection effects that are negative for growing occupations and positive for...

This study deals with the determinants of factor demand in 27 industries of the manufacturing sector during the period 1978 to 1990. Using a quadratic cost function, six production factors are distinguished: Capital, energy, three types of labour and intermediate materials. A parametric test of...

We present a new method for imposing and testing concavity of a cost function using asymptotic least squares, which can easily be implemented even for cost functions which are nonlinear in parameters. We provide an illustration on the basis of a (generalized) Box-Cox cost function with six...

This paper presents an application of the Generalised Error Correction Model (GECM) for heterogeneous factor demands based on the quadratic cost function. Using data for 26 West German manufacturing industries over the period 1976-1995, it turns out that less general specifications such as the...

The growing occurrence and significance of labour migration from Bangladesh has become an important area of interest in policy research. However, little attention has been given to understand and study the inadequacies in policy that support cross border movements within irregular migration....

Running RIF regressions to decompose wage differences along the distribution, this is the first study documenting that worker-level variation in tasks has played a key role in the widening of the Native-Foreign Wage Gap. Comparing variation in Individual- vs Occupation-level task measures...
