Child Benefit and Fiscal Burden in the Endogenous Fertility Setting

This paper analyzes the possibility of improving the efficiency of child benefit programs in an overlapping generations economy that has endogenous fertility and large government debt levels. We derive the conditions for this improvement using Representative-Consumer and Children-for-Representative-Consumers efficiency criteria in the endogenous fertility setting, as proposed by Michel and Wigniolle (2007). We find that the result crucially depends on the relative amount of accumulated government debt in the economy. When the elasticity of interest rates to child benefit is close to zero and there exists a huge amount of accumulated debt in the economy, financing child benefit programs by issuing debt and using lump-sum tax leads to RC-improvements. This finding is likely to hold in the economies of developed countries that have low fertility rates. We finally provide the implications of these findings on the real economy.
