In this paper we find evidence that the new economic geography approach is able to describe and explain the spatial characteristics of an economy, in our case the German economy. Using German district data we estimate the structural parameters of a new economic geography model as developed by...

Recent studies of border effects have focused on the intra-country and inter-country comparison of trade flows. It is found that borders have a negative impact on the size of cross-border trade. In order to estimate border effects on a regional level one needs not only data on inter-country but...

In a recent paper Edward Lazear proposed the jack-of-all-trades view of entrepreneurship. Based on a coherent model of the choice between self-employment and paid employment he shows that having a background in a large number of different roles increases the probability of becoming an...

Using a large recent representative sample of the German population this paper contributes to the entrepreneurship literature by empirically testing the hypothesis that young and small firms are hothouses for nascent entrepreneurs. The empirical estimation takes the rare events nature of...

This paper contributes to empirical research in entrepreneurship by focusing on the link between two stylized facts that emerged from a number of studies for Germany and other countries: Entry rates differ between regions, and the propensity to become an entrepreneur is influenced by...

This paper tests the theory recently put forward by Edward Lazear that individuals with competence in many skills should have a higher probability of being self-employed than others. The empirical results for Germany support this jack-of-all-trades view.

Although comprehensive data from official statistics on new firm formation and entrepreneurs starting a new business are lacking in Germany, we know from empirical studies that entry rates differ between regions, and that the propensity to become an entrepreneur is influenced by...

The focus of this paper is on the choice of the unemployed between becoming an entrepreneur or not. It contributes to the literature by empirically investigating two hitherto neglected issues: What is the impact of risk aversion and personal contact with a role model in shaping the decision to...

Many modern trade and growth models are characterized by multiple equilibria. In theory the analysis of multiple equilibria is possible, but in practice it is difficult to test for the presence of multiple equilibria. Based on the methodology developed by Davis and Weinstein (2004) for the case...

The evolution of city growth is usually studied for relatively short time periods. The rise and decline of cities is, however, typically a process that takes many decades or even centuries. In this paper we study the evolution of Italian cities over the period 1300-1861. The first contribution...
