In this paper, market risk at an intraday time horizon is quantified using normal GARCH, Student GARCH, RiskMetrics and high-frequency duration (log-ACD) models set in the framework of the conditional VaR methodology. Because of the small time horizon of the intraday returns (15 and 30 minute...

This short paper demonstrates two important results related to the estimation of competing-risk models under the proportional-hazards assumption with grouped duration data. First I show that the model with non-parametric baseline hazards is unidentifiable with only grouped duration data....

The instantaneous volatility of the price process is analyzed through the intraday financial durations between price changes. Previous research has traditionally dealt with parametric models without reaching a satisfactory level of adequacy. In this study, it is shown that by using a mixture of...

Early retirement is predominantly considered as the result of incentives set by social security and the tax system. But people seem to retire early even in the absence of such distortions as the Swiss example demonstrates. We look for determinants of early retirement, in particular the role of...

This paper studies inference in a continuous time game where an agent's decision to quit an activity depends on the participation of other players. In equilibrium, similar actions can be explained not only by direct influences but also by correlated factors. Our model can be seen as a...
