<p>This study analyzes how a social security system composed of a public pension, child allowances, and unemployment insurance affects endogenous fertility and unemployment when the wage level is endogenously set by monopolistic trade unions in an overlapping generations model. The analysis reveals, first, that increased pension tax rates lead to a higher fertility rate when wages are higher but a lower rate when wages are lower. Second, an increased child allowances tax rates lead to an increased fertility rate when wages are lower but a decreased rate when wages are higher. Therefore, both social security and wage setting should be considered in order to improve fertility and reduce unemployment.</p>
