We aim at obtaining a simple quantitative rule for the joint determining of optimal corporate investment and financing policies in an intertemporal setting. A novel general continuous-time framework, inspired by the optimal portfolio design literature, is first built. We derive the optimal...

The paper deals with taxation effects on optimal portfolio rules of de fined contribution (DC) and de fined benefi t (DB) pension funds in a continuous-time setting. Following practice, three tax types are considered: on contributions, investment gains and pensions. We focus on the tax effects...

The delta hedge, constituting the benchmark method when covering a position in an option, does not define the optimal investment strategy, even in the original Black and Scholes (1973)' (BS) setting. We propose the definition of the optimal alternative to the delta neutral cover in the original...
