This paper investigates the effect of locus of control (LOC) on the length of mothers’ employment break after childbirth. Using data from the German Socio-Economic Panel Study (SOEP), duration data reveals that women with an internal LOC return to employment more quickly than women with an...

This paper develops and estimates a joint hazard-longitudinal (JHL) model of the timing of migration and labor market assimilation – two processes that have been assumed to be independent in the existing literature. The JHL model accounts for the endogenous age of entry in estimating the...
