We derive analytically the first four conditional moments of the integrated variance implied by the GARCH diffusion process. From these moments we obtain an analytical closed-form approximation formula to price European options under the GARCH diffusion model.Using Monte Carlo simulations, we...

Assets and liabilities management practices currently in use are reviewed. Some of the improvements currently under development are presented. Potential problems in the application of current ALM techniques to universal banks are considered

This paper develops and tests the notion that it is possible to use the post-announcement prices from the stock and option markets to infer both the probability of success and timing of an attempted takeover. Using a sample of 65 cash tender offers from the period January 1980 to July 1989, we...

This paper presents a characterization of callable bond pricing and call decision when there are transactions costs. When capital structure is kept constant a firm that has outstanding callable bonds refinances them with similarly structured callable bonds. Since refinancing is costly, firms...

We propose a simple class of multivariate GARCH models, allowing for time-varying conditional correlations. Estimates for time-varying conditional correlations are constructed by means of a convex combination of averaged correlations (across all series) and dynamic realized (historical)...

The pricing of bonds and bond options with default risk is analyzed in the general equilibrium model of Cox, Ingersoll, and Ross (Cir, 1985). This model is extended by means of an additional parameter in order to deal with financial and credit risk simultaneously. The estimation of such a...

The daily term structure of interest rates is filtered to reduce the influence of cross-correlations and autocorrelations on its factors. A three-factor model is fitted to the filtered data. We perform statistical tests, finding that factor loadings are unstable through time for daily data. This...

We propose a new method for pricing options based on GARCH models with filtered historical innovations. In an incomplete market framework, we allow for different distributions of historical and pricing return dynamics, which enhances the model's flexibility to fit market option prices. An...

The dynamics of the physical probability of firms that undertake a stock swap merger is developed through a simple model. Using a sample of 1090 deals from 1992 to 2008, we show how movements in target stock prices are informative of the success or failure of a stock swap merger and how...
