Enough Potential Repudiation: Economic and Legal Aspects of Sovereign Debt in the Pandemic Era
回顾了新冠疫情冲击下主权债务的经济与法律文献，指出基于豁免权的理论与中低收入国家大量借贷的现实之间存在差距，并建议将关注点从豁免权转向主权权威以弥合分歧。
This article reviews recent economic and legal literature on sovereign debt in light of the COVID-19 shock. Most of the core theoretical contributions across the two disciplines hinge on immunity, and the sovereign borrower's consequent inability to commit to repay foreign creditors, as the distinguishing attribute of sovereignty. We highlight a persistent gap between sovereign debt theories grounded in immunity and empirical evidence that the governments of low- and middle-income countries borrow far more than theory would predict. On the other hand, the governments of advanced economies, generally viewed as outside the scope of this literature before the euro area debt crisis, have shown themselves to be far more commitment challenged than previously supposed. We conclude that the traditional split between a literature concerned with developing economy sovereigns that repudiate debt and one concerned with advanced economies that do not is no longer appropriate (if ever it was). We argue that shifting some attention away from immunity to a different attribute of sovereignty—authority—could help bridge the gap between the two literatures.
