We analyze the production process of Ph.Ds in economics in the Netherlands. Our empirical results are consistent with the incentives that the actors in this process face. Universities succeed in making students who are unlikely to graduate or will need a long time to graduate quit the program....

Este trabajo analiza el problema de la deserción estudiantil en la Facultad de Economía de laUniversidad del Rosario, a través del estudio de los factores individuales, académicos ysocioeconómicos sobre el riesgo de desertar. Para esto se utiliza el análisis de modelos de...

This paper analyzes the determinants of the student’s drop-out in the Department of Economics at the Universidad del Rosario, throughout the study of the individual, academic, and socioeconomic background over the desertion risk. In this analysis a duration model is performed with the aim of...

Since the early 1980s, the econometric analysis of duration variables has become widespread. This chapter provides an overview of duration analysis, with an emphasis on the specification and identification of duration models, and with special attention to models for multiple durations. Most of...

When a treatment unambiguously defines the treatment and control groups at a given time point, its effects are usually found by comparing the two groups' mean responses. But there are many cases where the treatment timing is chosen, for which the conventional approach fails. This paper sets up...

Using a proportional hazard model with multiple exits, this paper analyzes whether immigrants' unemployment spells differ from natives', and if so, how the difference vary with time spent in Sweden and across immigrant cohorts. A unique data set taken from the Swedish unemployment registers is...

We study the relationship between offshoring and job stability in Italy in the period 1995-2001 by using an administrative dataset on manufacturing workers. We find that the international fragmentation of production negatively affects job stability. Service offshoring and material purchases from...

This paper investigates some common determinants of default probability changes ofindividual firms using Standard & Poor's ratings database. We analyze and quantify the re-sponses of hazard rates to changes in various economic variables, namely financial markets,business cycle and credit...

Using a proportional hazard model with multiple exits, this paper analyzes whether immigrants' unemployment spells differ from natives', and if so, how the difference vary with time spent in Sweden and across immigrant cohorts. A unique data set taken from the Swedish unemployment registers is...

In survival analysis, Cox?s name is associated with the partial likelihood technique that allows consistent estimation of proportional hazard scale parameters without specifying a duration dependence baseline. In discrete choice analysis, McFadden?s name is associated with the generalized...
