We derive a precautionary demand for international reserves in the presence of sovereign risk and show that political-economy considerations modify the optimal level of reserve holdings. A greater chance of opportunistic behavior by future policy makers and political corruption reduce the demand...

The utility maximization problem of ratchet investors who do not tolerate any decline in their consumption rate is solved explicitly for all felicity functions in a Markovian framework which includes Brownian motion and Poisson processes as special cases. The optimal consumption plan turns out...

We reconsider the optimal consumption choice of investors who do not tolerate any decline in their consumption rate. We connect the demand behavior of such agents to the behavior of standard time-additive agents. With consumption ratcheting, the investor demands the running maximum of the...

When people decide about saving and consumption across the various periods of their life time they take into account their life expectancy when comparing present and future needs and resources for satisfying them. The experimental design, applied at two sites (Humboldt-University at Berlin and...

This paper provides a model in which a long-term investor chooses consumption and optimal dynamic asset allocation, including a riskless bond, risky stock, and derivatives on the stock, when there is predictable variation in return volatility. We maximize a more general recursive utility...
