CAPM-pricing provides a good benchmark for equilibrium prices even when agents are not mean-variance optimizers and returns … preferences, endowments and dividends and compare the equilibrium prices and portfolio-holdings to the predictions of the CAPM …. While the CAPM does not hold exactly for the chosen specification, it turns out that pricing errors are extremely small …

We address the multi-period portfolio optimization problem with the constant rebalancing strategy. This problem is formulated as a polynomial optimization problem (POP) by using a mean-variance criterion. In order to solve the POPs of high degree, we develop a cutting-plane algorithm based on...

This paper generalizes the theory of irreversible investment under uncertainty by allowing for risk averse investors in … the absence of com-plete markets.Until now this theory has only been developed in the cases of risk neutrality, or risk … price that distinguishes price regions in which it is optimal for a risk averse investor to invest and price regions in …

positive relationship between risk taking and retirement fl exibility is weakened - and under some conditions even turned … around - if not only capital-market risks but also productivity risks are considered. Productivity risk in combination with a … labour income, reducing the willingness of consumers to bear risk. Moreover, it turns out that general-equilibrium effects …

We introduce an accurate, easily implementable, and fast algorithm to compute optimal decisions in discrete-time long-horizon welfaremaximizing problems. The algorithm is useful when interest is only in the decisions up to period T, where T is small. It relies on a flexible parametrization of...
