Abstract

In overlapping-generations economies with life-cycle saving and exogenous growth, the laissez-faire equilibrium balanced growth path fails in general to achieve optimality, but is dynamically efficient if the marginal product of physical capital is greater than the growth rate of the economy. In this paper, we accommodate the concept of dynamic (in)efficiency in an overlapping-generations economy with endogenous growth due to human capital accumulation. We show that the condition that the marginal product of physical capital is larger than the growth rate of the economy is necessary but no longer sufficient for the dynamic efficiency of the laissez-faire equilibrium balanced growth path.
