This paper analyzes the optimality of macroeconomic policies in Iran during the third five year development plan (2000-2004). For this purpose, we develop and use a macro econometric model for Iran. We determine optimal monetary and fiscal policies as solutions of optimum control problems with a...

The paper investigates the impact of adding a shortfall risk constraint to the problem of a portfolio manager who wishes to maximize his utility from the portfolios terminal wealth. Since portfolio managers are often evaluated relative to benchmarks which depend on the stock market we capture...

We study a Hamilton-Jacobi-Bellman equation related to the optimal control of a stochastic semilinear equation on a Hilbert space X. We show the existence and uniqueness of solutions to the HJB equation and prove the existence and uniqueness of feedback controls for the associated control...
