The existence of a unique optimum, a unique optimal stationary program, and a turnpike theorem are demonstrated for a neoclassical one sector optimal growth model. The planner's allocation problem is formulated as a discrete time deterministic, infinite horizon programming model. The production...

We reconsider the theory of Thompson aggregators proposed by Marinacci and Montrucchio. We prove a variant of their Recovery Theorem establishing the existence of extremal solutions to the Koopmans equation. We apply the constructive Tarski-Kantorovich Fixed Point Theorem rather than the...

We reconsider the theory of Thompson aggregators proposed by Mari-nacci and Montrucchio. We demonstrate the Koopmans equation has a unique utility function solution given a Thompson aggregator. Uniqueness holds only on the interior of the commodity spaces positive cone.Our proof veries the...

We reconsider the theory of Thompson aggregators proposed by Marinacci and Montrucchio (2010). We demonstrate the Koopmans equation has a unique utility function solution given a Thompson aggregator. Uniqueness holds only on the interior of the commodity space's positive cone. We verify Du's...
