本文建構一個內生成長模型,並將勞動內生化,以長期經濟成長率的觀點來探討內債與外債之優劣。本文最終發現內外債比與經濟成長率呈現反向的變動關係,也就是政府發行外債下的經濟成長率會高於內債之發行。 We examine the relationship between internal and external debt from government, and long-run economic growth rate in an endogenous growth model with elastic labor supply. We find that there is a negative relationship between internal-external ratio and the economic growth rate. That is, the economic growth rate under external debt is higher than that under internal debt.
