Child Benefit and Fiscal Burden: OLG Model with Endogenous Fertility

Property rights and efficiency in OLG models with endogenous fertility

Is there an economic rationale for pronatalist policies? We propose and analyze a particular market failure that leads to inefficiently low fertility in equilibrium. The friction is caused by the lack of ownership of children: if parents have no claim on their children’s income, the private benefit from producing a child can be smaller than the social benefit. We analyze an overlapping-generati...

Public Debt, Child Allowances and Pension Benefits with Endogenous Fertility

The public debt stock in some economically developed countries continues to increase because of a lack of tax revenues and the concomitant burdens of social security. Many of those countries suffer from lower birth rates and consequently, have fewer children. Child allowances might be an effective way to increase fertility, leading to higher future tax revenues through an increase in the number...

Efficient Endogenous Fluctuations in Two-Sector OLG Model

We consider a two-sector two-good two-periods overlapping generations model with inelastic labor, consumption in both period of life and homothetic CES preferences. There are two consumption goods, one pure (non-durable) consumption and one consumable (durable) capital good which can be either consumed or invested. Assuming gross substitutability and a capital intensive pure consumption good, w...

The Diamond OLG Model

Complex dynamics in an OLG model of neoclassical growth with endogenous retirement age and public pensions

This study analyses the dynamics of a general equilibrium, overlapping-generations (closed) economy with pay-as-you-go public pensions and tax-financed health investments that affect the retirement timewhen old. Life of the typical agent is divided between youth (firth period) and old age (second period). The latter period of life is, in turn, divided betweenwork time and retirement time in a p...
