We consider infinite-horizon deterministic dynamic programming problems in discrete time. We show that the value function is always a fixed point of a modified version of the Bellman operator. We also show that value iteration monotonically converges to the value function if the initial function...

We consider optimization problems involving coherent risk measures. We derive necessary and sufficient conditions of … optimality for these problems, and we discuss the nature of the nonanticipativity constraints. Next, we introdice dynamic risk … equations are developed. The theoretical considerations are illustrated with many examples of mean-risk models applied in …

Concern over the appearance of algal blooms in Summer months on Australian waterways has been increasing in recent years. Some algae are toxic to humans and livestock when ingested. To avoid the dangers of contaminated drinking water, costs must be incurred, either by eliminating nutrient...

We introduce an axiomatic definition of a conditional convex risk mapping. By employing the techniques of conjugate … duality we derive properties of conditional risk mappings. In particular, we prove a representation theorem for conditional … risk mappings in terms of conditional expectations. We also develop dynamic programming relations for multistage …

It is argued in this paper that static approaches to weed management, where the benefits and costs are only considered within a single season, are inappropriate for assessing the economic benefits of weed control technologies. There are carryover effects from weed management as weeds that escape...
