This paper tries to identify, for the first time, a chronology for the Portuguese business cycle and test for the presence of duration dependence in the respective phases of expansion and contraction. A duration dependent Markov-switching vector autoregressive model is employed in that task....

[Background] There is an agreement in the fact that cancer incidence in transplant recipients increases at a rate disproportionately greater than in the general population. Several clinical studies have identified cancer risk factors, such as age, male gender, tobacco, UV radiation, viral...

The purpose of this study is to investigate the effect of time- aggregation in discrete and continuous-time hazard models. A Monte Carlo study is conducted in which data are generated according to underlying continuous and discrete-time processes, which data are aggregated into daily, weekly and...

The purpose of this study is to investigate the effect of time-aggregation in discrete and contunous-time hazard models. A Monte Carlo study is conducted in which data are generated according to underlying contunous and discrete-time processes, which data are aggregated into daily, weekly and...

Many widely used models, including proportional hazards models with un- observed heterogeneity, can be written in the form (Y ) = min[ 0 X + U; C], where is an unknown increasing function, the error term U has unknown distribution function and is independent of X, C is a random censoring...

If fertility reflects the choice of households, results of their choice (duration between successive births and health of the children) cannot be considered to be randomly determined. While most existing studies of child health tend to overlook the effects of fertility selection on child health,...

Este documento analiza la relación que existe entre el trabajo no remunerado y la duración del desempleo desde una perspectiva de género, teniendo en cuenta que las mujeres tienen mayor participación y realizan más actividades de cuidado y trabajo doméstico no remunerado con respecto a los...

This paper examines whether there exists obstacles hindering women's ascension in the largest firms of the Brazilian manufacturing industry. In particular, we check whether gender matters in the time it takes to get a promotion to a managerial position. Once we control for covariate-dependent...

This paper applies duration and competing risk models to individual-level data on unemployment spells from the 1993-2003 labour force surveys in Italy. We aim to assess whether labour market intervention and regulations introduced in the nineties acted in the expected direction, that is reducing...
