Abstract
The paper aims to ascertain the extent to which saving and fertility decisions are affected by the availability and attractiveness of market-based or state-provided alternatives to the family as a source of old-age support. Subordinately, the paper aims to bring evidence to bear on the assumption that fertility is endogenous and jointly determined with saving, and to test two alternative hypotheses about individual motivations. The saving and fertility implications of two alternative models of family choice — based one on the assumption of pure self-interest, the other on that of intergenerational altruism — are first derived theoretically. Saving and fertility equations are then estimated from Italian time-series data, using as explanatory variables the market rate of interest, the social security deficit, various measures of capital market accessibility and social security coverage, and a number of income and wage variables. Particularly worthy of note is the result that a fully-funded increase in social security coverage raises saving, while an increase in the social security deficit has the opposite effect. The empirical findings appear to support the assumption that fertility is endogenous and jointly determined with saving, and to favour the hypothesis that individual decisions are motivated by self-interest rather than intergenerational altruism. Some of the policy implications are briefly discussed in the concluding section.
