A pay-as-you-go pension scheme is associated with positive externalities of having children and providing them with human capital. In a framework with heterogeneity in productivity, and stochastic and endogenous investment in fertility and education, we discuss internalization policies...

This study compares alternative designs of an unfunded pension system. Convex combinations between a fixed contribution rate and a fixed benefit rate are considered. The objective is to maximize the expected ex-ante welfare under stochastic fertility. The model is a three-period CGE framework...

Conventional pension systems suffer from a design defect which makes them financially unsustainable, and a source of inefficiency for the economy as a whole. The paper outlines a second-best policy which includes a public pension system made up of two parallel schemes, a Bismarckian one allowing...

This paper provides a unified treatment of externalities associated with fertility and human capital accumulation as they relate to pension systems. It considers as overlapping generations model in which every generation consists of high earners and low earners with the proportion of types being...

In an overlapping-generations model with endogenous birth rates, I design a reform of the pay-as-you-go pension system, which internalises positive externalities of children - their pension contributions. Individuals may differ in their preferences for children and their ability to have children...

The paper re-examines the idea that a family can be viewed as a community governed by a self-enforcing constitution, and extends existing results in two directions. First, it identifies circumstances in which a constitution is renegotiation-proof. Second, it introduces parental altruism. The...

Why do people have kids in developed societies? We propose an empirical test of two alternative theories - children as consumption" vs. investment" good. We use as a natural experiment the Italian pension reforms of the 90s that introduced a clear discontinuity in the treatment across workers....

We investigate the effect of having a child on parents' criminal behavior using rich administrative data from Brazil. Fathers' criminal activity sharply increases by up to 10% during the pregnancy period, and by up to 30% two years after birth, while mothers experience only a transitory decline...
