The extension of GARCH models to the multivariate setting has been fraught with difficulties. In this paper, we suggest to work with univariate portfolio GARCH models. We show how the multivariate dimension of the portfolio allocation problem may be recovered from the univariate approach. The...

This article empirically faces the lively debate over the choice of an appropriate copula function to be used to price and risk monitor some credit derivatives products. We consider the explicit pricing of collateralized debt obligations and basket default swaps, and empirically examine these...

Basel 3 has incorporated valuation adjustment in calculations of regulatory capital for counterparty credit risk, introducing an important element for the pricing and risk management of derivatives portfolios. The use of an advanced or standardized Cva risk capital charge method depends on...

We propose formal and quantitative measures of the risk that future inflation will be excessively high or low relative to the range preferred by a private sector agent. Unlike alternative measures of risk, our measures are designed to make explicit the dependence of risk measures on the private...

This paper argues that forecast estimators should minimise the loss function in a statistical, rather than deterministic, way. We introduce two new elements into the classical econometric analysis: a subjective guess on the variable to be forecasted and a probability reflecting the confidence...

In deciding the monetary policy stance, central bankers need to evaluate carefully the risks the current economic situation poses to price stability. We propose to regard the central banker as a risk manager who aims to contain inflation within pre-specified bounds. We develop formal tools of...

This paper studies the determinants of interest rate spreads of euro area 10 year government bonds against the benchmark, the German bund, after the introduction of the euro. In particular, it pays attention to the question whether market discipline is advanced or obstructed by financial...

Policy impact studies often suffer from endogeneity problems. Consider the case of the ECB Securities Markets Programme. If Eurosystem interventions were triggered by sudden and strong price deteriorations, looking at daily (or weekly) price changes may bias downwards the correlation between...
