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...

Firms' labor demand responses to wage changes are of key interest in empirical research and policy analysis. However, despite extensive research, estimates of labor demand elasticities remain subject to considerable heterogeneity. In this paper, we conduct a comprehensive meta-regression...

In this study we investigate the minimum wage (MW) effects for a German sub-construction sector where the MW bites extraordinary hard by international standards. Within a quasiexperiment we estimate the Quantile Treatment Effects of the MW on the conditional and unconditional distribution of...
