Along with a relatively minor spreadsheet error, they identified some methodological choices in the original Reinhart/Rogoff work that threw the robustness of their results into question. Most important, even though debt levels and growth remained negatively correlated, the evidence for a 90% threshold was revealed to be quite weak.
除一处相对次要的电子表格错误外，他们发现莱因哈特/罗格夫研究所采用的某些方法使人对结果的可靠性产生了怀疑。最重要的是尽管债务水平和经济增长呈负相关关系，但90%临界值的设定却缺乏事实依据的支撑。而且就像很多人指出的那样，这种关系可能是由低增长引发高负债、而不是反向过程所导致的。
