Capital Externalities in Two-Sector Models

Alain Venditti

Working Papers from HAL

Abstract: We consider a two-sector economy with positive capital externalities and constant social returns. We first show that local indeterminacy does not require externaleffects from labor but is fundamentaly based on externalities derived from capital in the investment good sector. Second, we show that the external effects in the investment good sector has to be characterized by a low enough amount of capital stock from theconsumption good sector. In other words, the existence of multiple equilibria is ruled out if the externalities are too intersectoral.
