This paper focuses on Social Security benefit claiming behavior, a take-up decision that has been ignored in the previous literature. Using financial calculations and simulations based on an expected utility maximization model, we show that delaying benefit claim for a period of time after...

This study offers a simultaneous equations model of the birth process with seven endogenous variables: four birht inputs, and three birth outputs. Our analysis conditions on twenty-four exogenous variables. The data are taken the NLSY. Separate analyses are performed on five different groups:...

Dans ce papier, nous presentons un certain nombre de techniques qui peuvent etre derivees de l'algorithme de Kohonen, telles que la representation des contenus des classes, la visualisation des distances entre les classes, une rapide et robuste classification a deux niveaux emboites bases sur...

In this paper, we apply a collection of parametric (Normal, Normal GARCH, Student GARCH, RiskMetrics and high-frequency duration models) and non-parametric (empirical quantile, extreme distributions models) Value-at-Risk (VaR) techniques to intraday data for three stocks traded on the New York...

Using density forecasts, we compare the predictive performance of dur ation models that have been developed fo modelling intra-day data on stock markets. Our model portfolio encompasses the auto regressive conditional duration (ACD) model, its logarithmic version (Log-ACD), the threshold...
