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...

The stock of public debt in some developed countries continues to increase because of a lack of tax revenues and the burdens of social security. Many of those developed countries suffer from lower birth rates. Child allowances might help to raise fertility, leading to higher tax revenue in the...

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...

Mostly, all developed countries have the problem that the total fertility rate is below its sustainable level. Therefore, all these countries face economic problems caused by a demographic change. In this paper, we show that given certain conditions a pay-as-you-go pension system where the...

To compare the systems of child benefits and of family tax deductions, we create a model with endogenous fertility and a basic income, 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.

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...

In this work we analyse the issue of optimal taxation and of policy changes in an endogenous growth model driven by public expenditure, in the presence of endogenous fertility and labour supply. While normative analysis confirms the Chamley-Judd result of zero capital income tax, positive...

We simulate a two period olg-model with heterogeneous agents. Parents receive utility from quantity and quality of their offspring. Generating a trade-off between the former and the latter, an increasing wage rate leads to higher opportunity costs, lower fertility, and higher quality of the...
