本計畫擬在考慮生產部門,存在資本與勞動要素的生產外部性,而家計部門從事 勞動供給與育兒決策的情況下,架構一內生成長模型,討論育兒津貼政策對於人口成 長與經濟成長率的影響。本計畫在人口成長率與經濟成長率均為內生的架構下,探討 人口成長率與經濟成長率間的關係,並將與實際資料比較,驗證理論之模型是否足以 解釋實際之經濟現象。同時也將探討,用以解決人口老化危機的育兒津貼政策,其政 策效果為何。 This project constructs an endogenous growth model with capital and labor externalities in the production sector and endogenous consumption and fertility in the house sector. First, we explore the relationship between economic growth and fertility rates and examine whether it is coincide with the empirical result. Second, we investigate the policy implication of rearing-cost subsidy.
