Abstract

We consider a discrete-time two-sector CES (constant elasticity of substitution) economy with sector specific external effects and nonlin- ear preferences. Our goal is to examine carefully the influence of the utility curvature on the occurrence of multiple equilibria. We show that local in- determinacy depends on an interplay between factor substitutability and the elasticity of intertemporal substitution in consumption. Moreover, consider- ing that, when the external effects are set equal to zero, we get a two-sector optimal growth model, we study also the role of the utility curvature on the occurrence of competitive equilibrium cycles. We show that persistent en- dogenous fluctuations and macroeconomic volatility require a strong enough elasticity of intertemporal substitution in consumption.
