Variable annuities are insurance products that contain guarantees and using the Monte Carlo method to calculate the fair market values of these guarantees for a large portfolio of such products is extremely time consuming. In this paper, we propose the class of GB2 distributions to model the...

A variable annuity is a popular life insurance product that comes with financial guarantees. Using Monte Carlo simulation to value a large variable annuity portfolio is extremely time-consuming. Metamodeling approaches have been proposed in the literature to speed up the valuation process. In...

Regression of a trendless random walk on time produces R-squared values around .44 regardless of sample length. The residuals from the regression exhibit only about 14 percent as much variation as the original series even though the underlying process has no functional dependence on time. The...

In several OECD countries pension benefits are taxed away if retirees continue working and receive earnings that cross a threshold. Recently governments started to increase these earnings thresholds for working pensioners. On the basis of Belgian administrative data covering the years before and...

This paper proposes new ℓ1-penalized quantile regression estimators for panel data, which explicitly allows for individual heterogeneity associated with covariates. We conduct Monte Carlo simulations to assess the small sample performance of the new estimators and provide comparisons of new...
