T. Mitra et K. Nishimura, Discounting and long-run behavior: Global bifurcation analysis of a familyof dynamical systems, J ECON THEO, 96(1-2), 2001, pp. 256-293
This paper is concerned with the relationship between the discount rate and
the nature of long-run behavior in dynamic optimization models. The theory
is developed under two conditions. The first is history independence, whic
h rules out multiple limit sets. The second is a condition that avoids the
reversion to a stable steady state, as the discount factor is lowered, once
cycles have emerged. These conditions appear to be the minimal restriction
s that would allow analysis by a bifurcation diagram. The results are illus
trated by two well-known examples in this literature, due to Sutherland and
