We study cycles and chaos in economic models. Autonomous dynamical systems are considered through infinite time horizon optimization models. We first show how endogenous fluctuations arise in a multisector growth model. Secondly, we consider an extension of this model by allowing direct...

We consider a discrete-time two-sector Cobb-Douglas economy with positive sector specific external effects. We show that indetermincay of steady states and cycles can easily arise with constant or decreasing social returns to scale, and very small market imperfections. This is in sharp contrast...

We show that even under socially constant returns to scale indeterminacy, i.e., a continuum of dynamic general equilibrium paths converging to a common steady state, can arise in a dynamic Heckscher-Ohlin model with production externality and endogenous time preference in which production is...

This paper introduces sector-specific externalities in the Heckscher-Ohlin two-country dynamic general equilibrium model to show that indeterminacy of the equilibrium path in the would market can occur. Under certain conditions in terms of factor intensities, there are multiple equilibrium paths...

The purpose of this paper is to characterize the possibility of indeterminacy in multisector growth models that exhibit constant marginal returns to scale at the social level, with empirically realistic small external effects. Our results demonstrate that indeterminacy does not require...

This paper presents a simple overlapping generations model of small open economy with child-parent externality that exhibits chaotic equilirbium dynamics.
