Abstract

Some recent research indicates that the occurrence of indeterminacy in mod- els with externalities may be overstated because these models ignore agents’ heterogene- ity. We consider a neoclassical two-sector growth model with technological externalities. Agents are heterogenous in respect to their shares of the initial stock of capital and in labor endowments. We find that the sign of the effect of inequality on indeterminacy is not pinned down by the standard properties of preferences. However, when the in- verse of absolute risk aversion is a convex (respectively concave) function homogeneity (heterogeneity) tends to neutralize the external effects and eliminate indeterminacy.
