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...

This paper studies the effect of the Spanish Reconquest, a military campaign that aimed to expel the Muslims from the Iberian Peninsula, on the population of its most important cities. The almost four centuries of Reconquest offer a "quasi-natural" experiment to study the persistence of...

This paper analyses the determinants of growth of American cities, understood as growth of the population or of per capita income, from 1990 to 2000. This empirical analysis uses data from all cities with more than 25,000 inhabitants in the year 2000 (1154 cities). The results show that while a...

We construct a unique data set to analyze whether or not a large temporary shock had an impact on German city growth and city size distribution. Following recent work by Davis and Weinstein (2001) on Japan, we take the strategic bombing of German cities during WWII as our example of such a...

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...
