The present regulation of concentration risk does not take into consideration recent, sophisticated methods in credit risk quantification; the new Basle Capital Accord has left the regulatory treatment unchanged. Recently, substantial work has begun within the EU on this issue with the formation...

The point estimator used in naive Monte Carlo sampling weights all the computed function evaluations equally, and it does not take into account the precise locations at which the function evaluations are made. In this note, we consider one-dimensional integration problems in which the integrand...

Modeling dynamic systems can be made using several instruments and techniques, simulation being among these. Simulation … using a specific set of rules. In many cases, simulation is the only possible solution for making such evaluations. In this … work we’ll show general considerations about possibilities of simulation dynamic systems using dedicated programs for …

A proof of convergence is presented for a simplified numerical integration method for solving systems of correlated stochastic differential equations describing mean reverting geometric Brownian motion. Such systems arise in modelling the time evolution of interest rate term structures. For time...

This paper introduces an estimation procedure for a random effects probit model in presence of heteroskedasticity and a … likelihood ratio test for homoskedasticity. The cases where the heteroskedasticity is due to individual effects or idiosyncratic … heteroskedasticity. Furthermore, the power of the test increases with larger individual and time dimensions. The robustness analysis …

A new method is introduced for panel-data models. Asymptotic robustness is used for a multivariate model with latent variables for a family of estimators. It is shown numerically that in comparison to standard methods we obtain: 1) better predictions in out-of-sample occasions; 2) smaller...
