An optimum of a Markov decision process (MDP) is said to be myopic if it can be specified by solving a series of static problems. We identify new classes of MDPs with myopic optima and sequential games with myopic equilibrium points. In one of the classes the single-period reward is homogeneous...

The following result clarifies when preferences over time and under risk correspond to discounting and are not risk neutral. If a binary relation on a real vector space V satisfies four axioms, then there is a utility function U=fu from V to R where u from V to R is linear as a map of vector...
