Fertility rates are declining in many countries. But are fertility rates inefficiently low? This paper addresses this question by exploring the efficiency properties of equilibria in an overlapping generations setting with endogenous fertility and dynastic parental altruism, using a particular...

To compare the systems of child benefits and of family tax deductions, we create a model with endogenous fertility and basic income, also financed from proportional wage taxes. Pensioners are neglected but younger and older workers are distinguished: the former raise children and receive child...

To compare the systems of child benefits and of family tax deductions, we create a model with endogenous fertility and a basic income, also financed from proportional wage taxes. The deduction's efficiency is presumably lower than the benefit's and may even be lower than that of pure basic income.

Since the seminal work of Becker, the dynamics of endogenous fertility has been based on the trade-off faced by parents between the quantity and the quality of their children. However, in developing countries, when child labor is an indispensable source of household income, parents actually...

This paper explores the properties of the notions of A-efficiency and P-efficiency, proposed by Golosov, Jones and Tertilt (Econometrica, 2007), to evaluate allocations in a general overlapping generations setting in which fertility choices are endogenously selected from a continuum and any two...

This article studies socially optimal allocations, from the point of view of a benevolent social planner, in environments characterized by fixed resources, endogenous fertility, and full information. Individuals in our environment are fully rational and altruistic toward their descendants. Our...

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...

This paper investigates the problem of an \optimum population" concerning age structures in a 3-period OLG-model with endogenous fertility and longevity. The first-best solution for a number-dampened total social welfare function, including Millian and Benthamite utilitarianism as two extreme...

van Groezen, Leers and Meijdam (2003) (for short, GLM) analyzed combination of public pension and child support in an OLG model. We impose credit constraint on workers, and extend GLM's analysis from the case where workers do not understand the cost also to the case where they do. GLM's infinite...

A child-allowance system is to raise fertility beyond the individual optimum. The more heterogeneous the population with respect to rearing costs, however, the stronger are the redistribution and polarization.
