This paper studies a consumption-portfolio problem where money enters the agent's utility function. We solve the corresponding Hamilton-Jacobi-Bellman equation and provide closed-form solutions for the optimal consumption and portfolio strategy both in an infinite- and finite-horizon setting....

A widely applied diversification paradigm is the naive diversification choice heuristic. It stipulates that an economic agent allocates equal decision weights to given choice alternatives independent of their individual characteristics. This article provides mathematically and economically sound...

This paper studies pension design from a risk management point of view using a lexicographic loss aversion model. Interest in this model stems from the fact that it explains income expansion paths of equity and total savings particularly well. I find that all income groups are likely to benefit...

This letter develops a decision criterion which takes into account parameter and model uncertainty in an optimal portfolio choice problem. This criterion is a special case of the Variational Preferences, rewritten in the Bayesian statistics notations, which specifically exploits the information...
