Abstract: We consider a continuous-time two-sector infinite-horizon model with sector specific externalities, endogenous labor and a concave homogeneous non-separable utility function. We show that local indeterminacy arises with a low elasticity of intertempo- ral substitution in consumption provided the wage elasticity of the labor supply and the elasticity of substitution between consumption and leisure are low enough. Such a result cannot hold with additively-separable preferences for which local indeterminacy requires a large enough elasticity of intertemporal substitution in consumption.

Keywords: Sector-specific externalities; endogenous labor; non-separable concave ho- mogeneous utility functions; intertemporal substitution in consumption; local indetermi- nacy. (search for similar items in EconPapers)
