A MATHEMATICAL APPROACH TO INVESTMENT WITH CHARGE ON BALANCE AND VOLUNTARY CONTRIBUTIONS UNDER WEIBULL MORTALITY FORCE FUNCTION
Published 2025-01-01“…To achieve this, there is need to develop an optimal portfolio which considers the volatility of the stock market price consisting of one risk-free asset and a risky asset which follows the Heston volatility model (HVM). Also, the portfolio considers additional voluntary contributions (AVC) by members, tax on the stock market price, charge on balance (CB), and the mortality risk of the pension scheme members (PSM) modeled by the Weibull mortality force function. …”

Contextualizing GCM Biases in Low‐Cloud Coverage: The Role of Large‐Scale Conditions
Published 2025-07-01“…Here, we quantify the contribution of GCM LCC biases from both the macrophysical low‐cloud parameterizations, and the GCM simulation of large‐scale meteorological conditions, which control a large portion of observed LCC variability. We use a machine‐learning model trained to predict observed relationship between LCC and large‐scale conditions to perform the bias decomposition within nine CMIP6 GCMs in both coupled and atmosphere‐only configurations. …”
