Stabilization of metapopulation cycles: Toward a classification scheme
Theoretical Population Biology, 2008The stability of population oscillations in ecological systems is considered. Experiments suggest that in many cases the single patch dynamics of predator-prey or host-parasite systems is extinction prone, and stability is achieved only when the spatial structure of the population is expressed via desynchronization between patches.

Ecosystem Stability, Competition, and Nutrient Cycling
1994During the 1960s and 1970s ecologists paid much attention to the relationship between diversity and stability of ecosystems. It was generally believed that ecosystems that harbored many species were more stable than comparatively species-poor ecosystems (MacArthur 1955; Elton 1958; Van Leeuwen 1966; Margalef 1968).

Stability of limit cycles in hybrid systems
Proceedings of the 34th Annual Hawaii International Conference on System Sciences, 2005Limit cycles are common in hybrid systems. However the nonsmooth dynamics of such systems makes stability analysis difficult. This paper uses recent extensions of trajectory sensitivity analysis to obtain the characteristic multipliers of nonsmooth limit cycles. The stability of a limit cycle is determined by its characteristic multipliers.

On learning and the stability of cycles
1995We study a general equilibrium model where the multiplicity of stationary periodic perfect foresight equilibria is pervasive. We investigate the extent of which agents can learn to coordinate on stationary perfect foresight cycles. The example economy, taken from Grandmont (1985), is an endowment overlapping generations model with fiat money, where ...

Economic variables like GDP growth, employment, interest rates and consumption show signs of cyclical behavior. Many variables display multiple cycles, with lengths ranging in between 5 to even up to 100 years. We argue that multiple cycles can be associated with long-run stability of the economic system, provided that the cycle lengths are such that ...
