Using data from the German Socio-Economic Panel Study (GSOEP), we analyze whether necessity entrepreneurs differ from opportunity entrepreneurs in terms of self-employment duration. Using univariate statistics, we find that opportunity entrepreneurs remain in self-employment longer than...

This paper shows a somehow counterintuitive result: an increase in the exam difficulty may reduce the average quality (productivity) of selected individuals. Since the exam does not verify all skills, when its standard rises, candidates with relatively low skills emphasized in the test and high...

A parallel of education with transformative processes in standard markets suggest that a more severe control of the quality of the output will improve the overall quality of the education. This paper shows a somehow counterintuitive result: an increase in the exam difficulty may reduce the...

This paper addresses the problem of estimation of a nonparametric regression function from selectively observed data when selection is endogenous. Our approach relies on independence between covariates and selection conditionally on potential outcomes. Endogeneity of regressors is also allowed...

Our paper analyzes the interplay of organizational demography with the propensity to adopt an innovative practice. In particular, we examine how the demographical composition of professional German football teams influenced the adoption of the chain-defense-system (?Viererkette?) as well as the...

There are few studies on unemployment duration in developing countries. This is the first study on duration aspect of unemployment in Turkey. We use the results of the Household Labor Force Surveys of 2000 and 2001 to construct a cross-section of durations of unemployment spells. We analyze the...

This paper studies the impact of unemployment benefits on unemployment duration for East Germany using data from the German Socio-Economic Panel. It concentrates on exit from unemployment into employment. Estimation results of a discrete-time hazard rate model imply that moderate cuts in the...

The first period of the transition to a market economy was characterised by a high rate of job-change in many transition countries. This was no different for East Germany. This paper analyses the consequences of the transition process for East German workers in their old job. We quantify the...

In dieser Arbeit wird untersucht, welche individuellen Faktoren einen Einfluß auf das Auszugsverhalten junger Menschen in der Bundesrepublik (West) haben. Die Untersuchung wird auf der Basis von Daten des Sozioökonomischen Panels für die Geburtenjahrgänge von 1968-1982 durchgeführt. Es wird...

This empirical analysis of multiple durations using multivariate mixed proportional hazard rate models is widespread. In such models, the duration variable are dependent if their unobserved determinants are dependent on each other. In this paper it is shown that these models restrict the...
