本文以長期經濟成長率的觀點,比較所得稅融通與公債融通的優劣。本模型為一個生產具有外部性的單部門內生成長模型,並內生化勞動供給。本文發現: 從經濟成長率的觀點來看,政府支出以何種融通的方式較佳取決於公債利率與公債發行餘額成長率的大小。 This study develops a one-sector endogenous growth model to discusses the relative merits of income tax financing and bound financing from the point of view of long-term economic growth. We find that which financing get a higher economic growth rate depends on the interest rate and bond growth rate.
