This paper estimates a switching autoregressive conditional heteroskedastic time series model for returns on the daily German stock market index. Volatility clustering is captured by persistent periods of different volatility levels and by the dependence on past innovations. We introduce a...

This paper compares two specifications of the Capital Asset Pricing Model for a sample of German stocks. The specifications generate time-varying first and second moments by conditioning on past information. This explicit modelling of the time series behaviour of risk allows us to characterize...

We use an extensive data set of bilateral exposures on credit default swap (CDS) to estimate the impact on collateral demand of new margin and clearing practices and regulations. We decompose collateral demand for both customers and dealers into several key components, including the "velocity...

This paper analyses the network structure of the credit default swap (CDS) market and its determinants, using a unique dataset of bilateral notional exposures on 642 financial and sovereign reference entities. We find that the CDS network is centred around 14 major dealers, exhibits a “small...

In this paper, we study the regional and global integration of stock markets in Hungary, Poland and the Czech Republic. We estimate a vector autoregression with a multivariate GARCH component and perform a variety of diagnostic tests. Our main empirical result is the existence of limited...

This article investigates the pricing of subprime mortgage risk using data for the ABX.HE indices, which have become a key barometer of market conditions during the recent financial crisis. After a discussion of ABX index mechanics and observed pricing patterns, we use regression analysis to...
