This paper presents a model inspired by the Unified Growth Theory, where reductions in adult mortality together with improvements in technological progress are the deep causes of the transition from a Traditional (Malthusian) Regime to a Pre-Modern Regime, characterized by the accumulation of...

In this paper we analyze the relationship between (adult) mortality and the long-run development of countries from an empirical and theoretical perspective. A quantitative exploration of the model shows that improvements in adult survival rates alone bring an economy towards a Malthusian regime...

We study an OLG model with child policies and a PAYG pension with endogenous retirement and fertility. The result of the planned economy is compared to the decentralized competitive equilibrium deriving optimal policies. We show that in the presence of a PAYG pension system, the optimal policy...

In this paper, we analyse the effects of demographic change on a PAYG pension system, financed with a defined contribution scheme. In particular we examine the relationship between retirement, fertility and pensions in a three-period overlapping generations model. We focus on both the case of...
