We consider HJM type models for the term structure of futures prices, where the volatility is allowed to be an arbitrary smooth functional of the present futures price curve. Using a Lie algebraic approach we investigate when the infinite dimensional futures price process can be realized by a...

We consider the problem of maximizing terminal utility in a model where asset prices are driven by Wiener processes, but where the various rates of returns are allowed to be arbitrary semimartingales. The only information available to the investor is the one generated by the asset prices and, in...

We consider interest rate models of Heath-Jarrow-Morton type where the forward rates are driven by a multidimensional Wiener process, and where the volatility structure is allowed to be a smooth functional of the present forward rate curve. In a recent paper [3], Björk and Svensson give...

Robert Merton opened a new chapter in finance with his two papers (Merton, 1969; Merton, 1971), reprinted in his book (Merton, 1992), on dynamic asset allocation. Aside from taking a decisive step away from Markowitz-style single-period models, these papers made the key link with stochastic control...

In this chapter, we consider the situation of an investor who manages a portfolio of assets partly funded by an external liability. This is the typical case for banks, insurance companies and hedge funds. Asset and liabilitymanagement (ALM) problems have generated a substantial literature and a...

The problem we have considered so far relates to the finite horizon criterion $$J_{RS}^\theta (t;\,x,\,h)\,: = \, - {1 \over \theta }\ln {\Bbb E}{e^{ - \theta F(t;\,x,\,h)}}$$. There is also a rich literature on risk-sensitive control problems set over an infinite horizon, including Bielecki and...
