This paper tries to identify, for the first time, a chronology for the Portuguese stock market cycle and test for the presence of duration dependence in bull and bear markets. A duration-dependent Markov-switching model is estimated over monthly growth rates of the Portuguese stock index for the...

In 2005, the Indian Government launched a conditional cash-incentive program to encourage institutional delivery. This paper studies the effects of the program on neonatal mortality using district-level household survey data. We model mortality using survival analysis, paying special attention...

Between one and two million migrants reside in cramped conditions in Nairobi’s slums without proper access to sanitation or affordable clean water. Children in such areas are exposed to enormous risks, health risks in particular. Using longitudinal data collected every four months during the...

High drop-out rates and low graduation rates have become an issue of growing interest for higher education institutions and academic authorities. Since 2003, the University of Antioquia started a process of identification of the main factors associated with this phenomenon. This article presents...

This paper examines the two-way relationship between birth interval and child survival and compares the behaviour of households in the Indian and Pakistani provinces of Punjab. Birth interval and child survival are modelled here as correlated hazard processes, allowing for mother- specific...

Endogenous sampling with matching (also called gmixed samplingh) occurs when the statistician samples from the non-right- censored subset at a predetermined proportion and matches on one or more exogenous variables when sampling from the right-censored subset. This is widely applied in the...

In view of higher fertility and mortality rates in Pakistan compared to India, this paper examines the two-way relationship between birth interval and child mortality and compares the behaviour of households in the Indian and Pakistani provinces of Punjab. Birth interval and child survival are...

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...
