We propose a reduced form model for default that allows us to derive closed-form solutions to all the key ingredients in credit risk modeling: risk-free bond prices, defaultable bond prices (with and without stochastic recovery) and probabilities of survival. We show that all these quantities...

We start by presenting a reduced-form multiple default type of model and derive abstract results on the influence of a state variable X on credit spreads, when both the intensity and the loss quota distribution are driven by X. The aim is to apply the results to a concrete real life situation,...

This paper contains two novelties. First, a unified framework for testing and evaluating the adequacy of an estimated autoregressive conditional duration (ACD) model is presented. Second, two new classes of ACD models, the smooth transition ACD model and the time-varying ACD model, are...

The incidence and duration of work-absence spells for a sample of Swedish blue-collar workers in 1990 and 1991 are analyzed using the Kaplan-Meier non-parametric estimator, discrete-time hazard regression as well as stratified Cox regression. We focus on the effect of economic incentives, i.e.,...

Modelling multivariate failure times in a competing risks setting is often performed by assuming independence between risks. However, by wrongly assuming independence, seriously biased parameter estimates may result. The aim of this paper is to evaluate a test for independence previously...

The incidence and duration of work absence spells for a sample of Swedish blue collar workers in 1991 are analyzed using the Kaplan-Meier estimator, discrete time hazard regression as well as stratified Cox regression. The main interest is directed towards the effect of economic incentives. The...

We study the product turnover in an industry and, in particular, the survival of new products. The data set consists of monthly sales of all products sold in the Swedish beer market over the time period of 1989-1995. The death rates of newly introduced products are high - out of 199 products an...
