Existence and uniqueness of growth cycles in post Keynesian systems

Economic Modelling, 2018, vol. 75, issue C, 293-304

Abstract: In this paper, we explore the existence and uniqueness of a limit cycle (or of a growth cycle) in a post Keynesian system in which investment is determined by the expected rate of profit. We find that a periodic orbit appears if the marginal effect of the expected rate of profit on investment is strong enough and that it is a unique limit cycle if the speed of revisions of expectation is fast enough.
