內容提要:
This lecture constructs a New Keynesian model with overlapping generations to study the impact of temporary and permanent increases in fiscal deficits financed by debt rollover policy when interest rates are lower than economic growth rates. This lecture will show that the debt rollover policy is feasible in the monetary regime, but leads to very slow-moving debt. For a temporary increase in fiscal deficits, this policy generates persistent inflation; while for a permanent increase, it leads to persistent disinflation. From the perspective of social welfare, in terms of financing a temporary increase in fiscal deficits, the debt rollover policy dominates the conventional fiscal rule; but if the increase is permanent, the debt rollover policy is dominated.
本次講座構建了一個具有世代交疊特征的新凱恩斯主義模型,用于研究在利率低于經濟增長率的情況下,通過債務展期政策為財政赤字的臨時性與永久性增加提供資金時所產生的影響。本次講座將表明,在貨幣制度下債務展期政策是可行的,但會導致債務的變動極為緩慢。對于財政赤字的臨時性增加而言,該政策會引發持續的通貨膨脹;而對于永久性增加,它則會導致持續的通貨緊縮。從社會福利的角度來看,就為財政赤字的臨時性增加提供資金而言,債務展期政策優于傳統的財政規則;但如果赤字增加是永久性的,債務展期政策則處于劣勢。
