The transition to market economies in an endogenous growth model with altruistic agents

This paper considers an endogenous transition from a self-sufficient traditional economy to a market economy and its consequences on fertility and growth. The transition can occur if private intergenerational transfers are unable to secure old-age consumption as adequately as savings on capital markets; otherwise individuals stay in the traditional economy unless the mass-production technology in the market economy is sufficiently more advanced than individually accessible technologies. Markets emerge only if per capita output exceeds a certain level given a fixed cost of forming markets. The transition reduces fertility and promotes growth under plausible restrictions.
