The adjustment for the cedent's retained risk after excess-of-loss reinsurance with reinstatements is calculated. Therefore we need a multivariate aggregate claims distribution. This distribution is easily given by a multivariate extension of Panjer's recursion. Numerical examples show the...

This paper further examines the bootstrap method proposed by Simar and Wilson (1998) for DEA efficiency estimators. Some simplifications are provided, and we provide Monte Carlo evidence on the coverage probabilities of confidence intervals estimated by the method.

The well-known Cramer-Lundberg approximation says that for large u, the ultimate ruin probability w(u) satisfies w(u)~Ce-Ru, where u is the initial reserve, R is the adjustment coefficient and C is a positive constant. Our aim in this work is to present a new expression for C in the classical...

Efficiency scores of production units are measured by their distance to an estimated production frontier. Nonparametric DEA estimators are based on a finite sample of observed production unites and radial distances are considered. We investigate the consistency and the speed of convergence of...

A consistent estimator for the spectral density of a stationary random process can be obtained by smoothing the periodigrams across frequency. An important component of smoothing is the choice of the span. In this paper, we propose a span selector originally developed for use in fitting...

In this paper, we develop a Bayesian analysis of semi-parametric binary choice model. The prior specification of the functional parameter, namely the distribution function of a latent variable, is of the Dirichlet process type and the prior specification of the Euclidean parameter, namely the...
