The market model of interest rates specifies simple forward or Libor rates as lognormaly distributed, their stochastic dynamics has a linear volatility function. This model is extended to quadratic volatility which is the product of a quadratic polynomial and a level-independent covariance...

It is well-known that Gaussian hedging strategies are robust in the sense that they always lead to a cost process of bounded variation and that a superhedge is possible if upper bounds on the volatility of the relevant processes are available, cf. El Karoui, Jeanblanc-Picque and Shreve (1998)...

This paper developes a model of optimal consumption and portfolio choice for infinitely-lived investors facing stochastic interest rates, solve it using an approximate analytical method, and evaluate the conventional wisdom.

This paper argues that book-to-market and size attributes represent sensitivities of firm returns to several risk factors, and in so doing they subsume the information in other attributes.

This paper analyzes optimal portfolio choice and consumption with stochastic volatility in incomplete markets.

This paper estimates a trivariate two-factor conditional version of the Intertemporal CAPM of Merton (1973).

This paper tests a conditional version of Adler and Dumas' (1983) International CAPM with regime switching GARCH parameters.

This paper reviews some recent developments in the area of optimal international portfolio diversification and investigates important issues for future research.

The question that this paper raise in this paper is how to choose the best mix of countries to diversify internationally? They compare several methods of asset allocation from a Swiss perspective over the period 1988-2001.

This paper delevops a tools to analyse the ordering of concordance of random vectors.
