Even in countries where there is a male-biased sex ratio, it is still possible for the marriage market to be balanced if men marry younger women and population is growing. We define a missing Brides Index to reflect the intensity of the possible imbalance at steady state, taking into account the...

Introduced by Samuelson (1975), the Serendipity Theorem states that the competitive economy will converge towards the optimum steady-state provided the optimum population growth rate is imposed. This paper aims at exploring whether the Serendipity Theorem still holds in an economy with risky...

We examine the pathways by which gender inequality affects fertility and hampers growth. We introduce several dimensions of gender inequality into a 2-sex OLG model with a non-unitary representation of household decision-making. We characterize a Malthusian corner regime which is characterized...

This paper develops a theory of optimal fertility behavior under mortality schocks. In a 3-periods OLG model, young adults determine their optimal fertility, labor supply and life-cycle consumption with both exogenous child and adult mortality risks. For fixed prices (real wages and interest...

This paper simulates the impact of a permanent fertility shock on economic growth, using endogenous versus exogenous growth OLG models. An endogenous growth model, with education as the engine of growth, dampens the negative impact of a decline in fertility on growth when compared with an...

In order to help in designing an accurate pension reform, we determine the optimal resource allocation in an endogenous fertility model generating a demographic transition. Extending Samuelson’s (1975) work in such a setting, we analyze the problem of the interiority of the optimal solution...

To cope with the observed drop in fertility, four policy options are generally considered : lowering pension benefits, increasing social security contributions, postponing retirement, and reducing public debt in advance. To assess the respective merits of these options, we analyze the optimal...

We study how economic growth is affected by demographics in an overlapping generations model with a realistic survival law. Individuals optimally chose the dates at which they leave school to enter the labor market and at which they retire. Endogenous growth arises thanks to the accumulation of...
