In a market consisting of a money market and one stock with
price process dS(t)=S(t)[a(t) dt + b dW(t) + g dM(t)] where W is a
Wiener process and M is a compensated Poisson process, an agent invests
his initial wealth in a portfolio to maximize utility of wealth at
terminal time T. The portfolio strategy may only depend on the observed
stock price S(t). The constants b and g may be inferred from this, but
not the unknown drift a(t). It is assumed to be a Markov process with
known states and rate matrix.We reduce the problem to a martingale
representation problem for Levy processes.
