The Reinhart/Rogoff paper is just a small part of a voluminous academic literature that shows high debt levels to be economically risky. A more fundamental question is causality: the state of the economy certainly affects the fiscal position, just as taxation, spending, deficits, and debts may affect economic growth.
莱因哈特/罗格夫论文只不过是揭示高债务水平带来高经济风险的大量学术文章的一小部分。一个更为根本的问题是因果关系：经济的状态显然影响着财政状况，正如税收、支出、赤字和债务可以影响经济增长。
