The study develops the methodology for a copula-based weather index insurance rating. As the copula approach is better … left tail of the joint distribution of a weather variable and the farm yield, we employ the Gumbel survival copula. Our … results indicate that, given the choice of an appropriate weather index to signal extreme drought occurrence, a copula …

We discuss the difficult question of measuring the effects of asymmetric information problems on resource allocation. Three problems are examined: moral hazard, adverse selection, and asymmetric learning. One theoretical conclusion, drawn by many authors, is that information problems may...

The issue of bonus in life insurance is considered in a model framework where the traditional set-up is extended by letting the experience basis (mortality, interest, etc.) be stochastic. A novel definition of the technical surplus on an insurance contract is proposed, and basic principles for...

In this paper, we address the mortality risk of individuals and adopt parsimonious time- homogeneous a±ne processes for their mortality intensities. We calibrate the models to different generations in the UK population and investigate their empirical appropriateness. We find that, in spite of...

in the dependence structure. Recently, two methods to analyze such changes using copula have been proposed. The first … approach only investigates the changes of copula parameters while ignoring the possibility of the changing for the copula … family. The other one stresses to inspect any change for copulas by determining the best copula on every subsamples divided …

The test is applied to a dataset of US large cap stocks to assess the performance of the Gaussian copula for the … portfolios of assets of various dimension. The Gaussian copula appears to be inadequate to characterize the dependence between …

Dynamic microsimulation modelling involves two stages: estimation and forecasting. Unobserved heterogeneity is often considered in estimation, but not in forecasting, beyond trivial cases. Non-trivial cases involve individuals that enter the simulation with a history of previous outcomes. We...

This paper analyzes the implications of unobserved heterogeneity in discrete-time, discrete-choice microsimulation models. We compare the predictions coming from simple pooled probit estimates with those obtained using random effect dynamic probit models, in a dynamic microsimulation of...
