Many studies have explored the determinants of entering into entrepreneurship and the differences in self-employment rates across racial and ethnic groups. However, very little is known about the survival in entrepreneurship of immigrants to the U.S. and their descendants. Employing data from...

This paper studies career mobility of white male doctorates in natural sciences and engineering using the Survey of Doctorate Recipients (1973-2001). The paper focuses on two issues. First, it assesses the relevance of doctoral careers to sciences and engineering (S&E) in general, and research...

This research develops semiparametric kernel-based estimators of state-specific conditional transition intensitiesm, hs (y|x), for duration models with right-censoring and/or multiple destinations (competing risks). Both discrete and continous duration data are considered. The maintained...

This paper analyses the transitions between the three states of non-employment, part-time and full-time work of a sample of married women living in West Germany. The questions addressed concern the dynamics of women`s labour market transitions and the association of the probability of transition...

This paper develops and compares specification tests for parametric duration models estimated with censored data. The tests are based on generalized residuals (the integrated hazard), which is exponentially distributed if the model is correctly specified. I present several conditional moment...
