The international transactions accounts provide information on trade in goods and services (including the balance of payments and the balance of trade), investment income, and government and private financial flows. In addition, the accounts measure the value of U.S. international assets and...

The Matching Distribution converges to a Poisson Distribution with ë = 1 as the parameter n converges to infinity. A generalization of the Matching Distribution is proposed. The properties of this Generalized Matching Distribution (GMD) turn out to be analogical to the case with ë = 1.

We examine the impact of performance groups on the estimation of therelative importance of ¯rm, industry and other e®ects on corporate performance.Performance groups comprise ¯rms from the same industry with asimilar performance over a longer period of time. We present a statisticalmethod...

In this paper we present a new approach to incorporate default dependency in intensity-based default risk models. The model uses an arbitrary default dependency structure which is specified by the Copula of the times of default, this is combined with individual intensity-based models for the...

In this paper a new credit risk model for credit derivatives is presented. The model is based upon the ‘Libor market’ modelling framework for default-free interest rates. We model effective default-free forward rates and effective forward credit spreads as lognormal diffusion processes, and...

This paper gives a simple introduction to portfolio credit risk models of the factor model type. In factor models, the dependence between the individual defaults is driven by a small number of systematic factors. When conditioning on the realisation of these factors the defaults become...

In this paper we present a tree model for defaultable bond prices which can be used for the pricing of credit derivatives. The model is based upon the two-factor Hull-White (1994) model for default-free interest rates, where one of the factors is taken to be the credit spread of the defaultable...

In this paper we examine the problem of partially hedging a given credit risk exposure. We derive hedges which satisfy certain optimality criteria: For a given investment into the hedge they minimize the remaining risk, or vice versa. This is motivated by the fact that it is a core business of...

The current paper presents a short survey of stochastic models of risk control and dividend optimization techniques for a financial corporation. While being close to consumption/investment models of Mathematical Finance, dividend optimization models possess special features which do not allow...

We develop a new approach to pricing and hedging contingent claims in incomplete markets framework the no-arbitrage arguments that have been developed in complete markets leads us to defining the concept we are able to extend the no-arbitrage ideo to a world of incomplete markets in such a way...
