T. Mitra, ON THE RELATIONSHIP BETWEEN DISCOUNTING AND COMPLICATED BEHAVIOR IN DYNAMIC OPTIMIZATION MODELS, Journal of economic behavior & organization, 33(3-4), 1998, pp. 421-434
This paper explores the relationship between discounting and complicat
ed behavior in dynamic optimization models. An inverse relationship be
tween the discount factor of a dynamic optimization model and the topo
logical entropy of the corresponding optimal policy function is establ
ished. For an aggregative model, this generalizes a result obtained by
Montrucchio and Sorger. The generalization makes it possible to apply
directly the results developed by Block, Guckenheimer, Misiurewicz an
d Young on the computation of the topological entropy of dynamical sys
tems to obtain upper bounds on the discount factor necessary for the o
ccurrence of topological chaos in aggregative dynamic optimization mod
