A Dynamic Correlation Modelling Framework with Consistent Stochastic Recovery

A Dynamic Correlation Modelling Framework with Consistent Stochastic Recovery

This paper describes a flexible and tractable bottom-up dynamic correlation modelling framework with a consistent stochastic recovery specification. In this modelling framework, only the joint distributions of default indicators are determined from the calibration to the index tranches; and the joint distribution of default time and spread dynamics can be changed independently from the CDO tran...

Modelling stochastic correlation

This work deals with the stochastic modelling of correlation in finance. It is well known that the correlation between financial products, financial institutions, e.g., plays an essential role in pricing and evaluation of financial derivatives. Using simply a constant or deterministic correlation may lead to correlation risk, since market observations give evidence that the correlation is hardl...

Modelling correlation as a stochastic process

Although market observations show that correlation between stocks, interest rates, e. g., is not deterministic, correlation is usually modelled as a fixed number. This article provides a new approach of modelling correlation as a stochastic process which has applications in many fields. We will show an example from financial markets where the stochasticity of correlation is a fundamental source...

Dynamic Facility Location with Stochastic Demand

Determination of facilities, such as factories or warehouses, location and availability conditions is one of the important and strategic decisions for an organization to make. Transportation costs that form a major part of goods price are dependent to this decision making. There are verity of methods have been presented to achieve the optimal locations of these facilities which are generally de...
