The paper deals with maritime risk, which we consider important, no doubt, for ship-owners acting in volatile markets …. Traditionally, risk is measured by "standard deviation". Other risk measures like "excess kurtosis", "excess skewness", "long …-term dependence" and the "catastrophe propensity" were ignored. Risk in 1900 was based on the mathematical laws of Chance and …

One of the main challenges for life actuaries is modeling and predicting the future mortality evolution. To this end, several stochastic mortality models have been proposed in literature, starting from the pivotal approach of the Lee-Carter model. These models essentially use the ARIMA processes...

This paper studies the impact of modelling time-varying variances of stock returns in terms of risk measurement and … extreme risk spillover. Using a general class of regime-dependent models, we find that volatility can be disaggregated into …. Volatility plays an important role in controlling and monitoring financial risks. Therefore, by means of a risk management …

We analyse models for panel data that arise in risk allocation problems, when a given set of sources are the cause of … an aggregate risk value. We focus on the modeling and forecasting of proportional contributions to risk. Compositional …
