GARCH option pricing models have the advantage of a well-established econometric foundation. However, multiple states need to be introduced as single state GARCH and even Levy processes are unable to explain the term structure of the moments of financial data. We show that the continuous time...

Fixed income analysts are accustomed to monitoring a few benchmark yields on a continuous basis and to providing point estimates for these yields, or for a combination of them. Yet, the optimisation of fixed income portfolios requires an accurate forecast of not only a few benchmark yields, but...

By using Moody's historical corporate default histories we explore the implications of scenarios based on the Great Depression for banks' economic capital and for existing and proposed regulatory capital requirements. By assuming different degrees of portfolio illiquidity, we then investigate...

Generalizations of traditional preference criteria such as the Sharpe ratio, the information ratio and the Jensen alpha are obtained by maximizing a certain equivalent excess return (CER) under relevant investment conditions. They are increasing functions of CERs and therefore equivalent...

We price multi-asset options by solving their price partial differential equations using a meshfree approach with radial basis functions under jump-diffusion and geometric Brownian motion frameworks. In the geometric Brownian motion framework, we propose an effective technique that breaks the...

The risk-capital positions of Japanese banks have been under tension throughout the 1990s. However, existing theory on the determinants of bank risk-taking still remains limited and the evidence is conflicting. Most studies concentrate on US and European banks, while empirical evidence has...

Medieval bishops condemned and restricted the sale of corrodies (a type of annuity), partly on the grounds of their perceived unprofitability. The available data on the profitability of corrodies is limited and little analysed, and the episcopal condemnation of corrodies has been adopted by...

There are two unique volatility surfaces associated with any arbitrage-free set of standard European option prices, the implied volatility surface and the local volatility surface. Several papers have discussed the stochastic differential equations for implied volatilities that are consistent...

There is a potential conflict of interest between a pension fund sponsor and future pensioners when they share unequally in the pension fund performance. Thus, when a scheme offers a yearly guaranteed minimum return to pensioners, as is presently the case with German Pensionskassen, the sponsors...

Even in the simple case that two price processes follow correlated geometric Brownian motions with constant volatility no analytic formula for the price of a standard European spread option has been derived, except when the strike is zero in which case the option becomes an exchange option. This...
