In an environment with stocks and short-term debt, random changes in the risk-reward frontier produce hedging demands for equities, implying that portfolio policies supporting optimal life-cycle consumption are rarely mean-variance efficient. Pursuing optimal life-cycle portfolio policies is...

This paper investigates strategic investment policies in a duopolistic continuous-time real options game. Our contribution is twofold, economic and methodological. The former is the recognition that, under fixed costs of investment and time-to-build, a firm's exercise of its capital-replacement...

We offer clarifications on Cooley and Quadrini (2001) regarding financial frictions and risky corporate-debt pricing. Even in a frictionless world, the promised rate on corporate debt is not identical across firms and across capital structures and it is not equal to the risk-free rate. Frictions...

While as a matter of pure chance and mathematical manipulations, the Black-Scholes formula could have been accidentally obtained much earlier by making use of put-call parity, a simple thought experiment demonstrates the inconclusiveness of any such derivation as regards the validity of the...

This paper exploits the early exercise premium representation to investigate strate- gic investment policies in a duopolistic continuous-time real options game. Assuming exogenous firm roles, we find that (i) as the leader installs its newly purchased capital, the follower's optimal investment...
