As applications of duration analysis have burgeoned in political science, scholars have become increasingly aware of the potential substantive importance of duration dependence: the extent to which the conditional hazards of the events of interest are rising or falling over time. Here I discuss the issue of duration dependence, focusing on the distinction between “spurious” dependence due to unobserved heterogeneity and “true” duration dependence due to state dependence in the process of interest. I present a simple extension of a commonly used parametric duration model—the Weibull model—which allows researchers to assess the influence of causal variables on the nature and extent of duration dependence in their data. I then illustrate the application of this “generalized Weibull” model using data on the duration of international alliances.

This article investigates whether there is state dependence in the gender composition of managers in German establishments; that is, whether the number of hired female managers depends on the past hiring decisions of an establishment. Using administrative data, the authors apply dynamic linear models, thereby accounting for unobserved heterogeneity and the endogeneity of lagged dependent variables. Results show that hiring female managers leads to the hiring of more female managers in the subsequent period. Hiring rates for male managers follow a similar pattern in that they are more likely to hire more male managers.
