This dissertation is based on three empirical studies on the thematic complex of the comparative advantages of self-employment and business start-ups out of unemployment. The first study examines the characteristics of persons who present a broad range of experience in terms of professional competencies. The extent to which self-reported entrepreneurial competence and the assessment of professionally self-employed activities correlate with the number of professional competencies acquired is examined in particular. It emerged from previous studies that the tendency to establish new businesses increases with the variety of experience. More recent studies show, however, that different causes may lie behind this correlation. The results of this study show that both entrepreneurial competence and the estimation of self-employment increase with the number of professional competencies. However, the analyses would indicate that entrepreneurial competence (self-assessment) is more strongly correlated and that an actual increase in qualifications lies behind the self-assessed entrepreneurial competence. Moreover, it emerges that self-assessed entrepreneurial competence increases at decreasing marginal rates with the number of professional competencies. The second study examines the extent to which professional background and, in particular, the professional and employment experience of an individual influence the duration he or she remains in self-employment. This is studied on the basis of data from a survey of founders who become self-employed out of unemployment. The study is based on the idea that individual characteristics can be used productively in different forms of employment and that specific competence and comparative characteristics affect the time-dependent exit from self-employment. The results initially confirm previous findings, in particular that firm characteristics do not play a very significant role in the decision to start up a business from a position of unemployment. Broad-based qualifications plus business skills, a high level of intrinsic motivation for self-employment and exploitable professional experience display a strong positive correlation with the duration in self-employment; this would suggest corresponding comparative advantages for self-employment. However, business skills alone reduce the time-dependent probability of survival in self-employment and accelerate exits into employment. The third study analyzes features of local labor markets in terms of their influence on the duration of self-employment. The basis of the study is provided by process-produced data generated by the German Federal Employment Agency on the employment biographies of individuals who received support in establishing businesses with a view to exiting unemployment. Individual characteristics were examined in addition to regional determinants. The idea behind the study is that local labor market conditions can have different comparative effects on income possibilities in both positions of employment and self-employment. The exit from self-employment is described as a change in work activity which arises following the evaluation of different income options. The results show that local labor market conditions have a considerable influence on the duration of self-employment and that the effect of local labor market conditions is very complex. The results would prompt the expectation that a one-dimensional perspective based on the local unemployment rate does not provide an adequate measure of general economic conditions. Increasing regional unemployment reduces the duration of self-employment while increasing uncertainty on the local labor market results in its extension. Moreover, all local characteristics display reducing to reversing marginal effects. Tests of individual characteristics show that persons from small businesses, master craftsmen and foremen, and persons with high income premiums remain longer in their last employment situation than the controls. These characteristics are clearly associated with comparative advantages for self-employment. The study also corroborates the impression that people with business backgrounds quickly leave self-employment for employed positions.
