Zhang (2008) defines the quotient correlation coefficient to test for dependence and tail dependence of bivariate random samples. He shows that asymptotically the test statistics are gamma distributed. Therefore, he called the corresponding test gamma test. We want to investigate the speed of...

Using a large representative German data set and various concepts of self-employment, this paper tests the jack-of-all-trades view of entrepreneurship by Lazear (AER 2004). Consistent with its theoretical assumptions we find that self-employed individuals perform more tasks and that their work...

Employing a standard matching unemployment model extended by within-labor-market-regions commuting, this paper analyzes the tradeoff between commuting costs and unemployment. Depending on whether commuters are able to bargain for fringe benefits, search may or may not be biased towards distant...

There are several procedures to construct a skewed distribution. One of these procedures is based on a symmetric distribution that will be distorted by a skewed distribution defined on (0; 1). This proposal stems from Arellano-Valle et al. and was refined by Ferreira and Steel. Up to now, it is...

This article studies the long run patterns and explanations of wage mobility as a characteristic of regional labor markets. Using German administrative data we describe wage mobility since 1975 in West and since 1992 in East Germany. Wage mobility declined substantially in East Germany in the...

This paper investigates the relative impact of microeconomic agglomeration mechanisms on plant’s total factor productivity (TFP) using German establishment and employment level data. Contrasting different strategies to estimate TFP from plant level production functions reveals that not...

Using a large representative German data set and various concepts of self-employment, this paper tests the 'jack-of-all-trades' view of entrepreneurship by Lazear (AER 2004). Consistent with its theoretical assumptions we find that self-employed individuals perform more tasks and that their work...

Combining a spatial equilibrium model with a matching unemployment model, this paper analyzes the regional quality of life when wages, rents, and unemployment risk compensate for local amenities and disamenities. In particular, the paper shows for quasi-linear utility that the effects of any...

This paper focuses on the role of the home country’s birth rates in shaping immigrant fertility. We use the German Socio-Economic Panel (SOEP) to study completed fertility of first generation immigrants who arrived from different countries and at different time. We apply generalized Poisson...
