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...

Modern systems of official statistics require the timely estimation of area-specific densities of sub-populations. Ideally estimates should be based on precise geo-coded information, which is not available due to confidentiality constraints. One approach for ensuring confidentiality is by...

This study investigates firm survival and employment growth of start-ups by unemployed people in East and West Germany as promoted by the Work Support Act (so called bridging allowances). In 1994, the services provided were improved considerably, which led to a sharp increase in the number of...

The US labour market is characterized by a high skill wage mark-up and low unemployment, while the German labour market has a low skill wage mark-up and a high, mainly unskilled unemployment rate. This paper adds an innovative labour supply explanation to the discussion how these distinct labour...

In this paper, we investigate whether an environmental tax reform 'cum' joint implementation (JI) provides employment and overall efficiency gains as compared to an environmental tax reform 'stand-alone' (ETR). We address this question in the framework of a large-scale general equilibrium model...

In an a priori view, it is usually assumed that the business cycle of manufacturing industries leads the business cycle of the service sector. This seems to be even more plausible for the relationship between business-related services, whose high growth rates in recent years were largely due to...

In this paper, we assess the impact of major German structural reforms from 1999 to 2008 on key macroeconomic variables. By many, these reforms, especially the Hartz reforms on the labor market, are considered to be the root of observed imbalances in the Euro Area. Our simulations within a...

To assess the influence of nonstandard employment for the labor market participation of different demographic groups, we provide detailed descriptions of the development of atypical employment in comparison to standard employment, unemployment, and economic inactivity between 1996 and 2011. In...
