I agree with most of Greg Mankiw’s NYTimes piece on long-term debt to GDP but can’t overlook a glaring omission – he seems to ignore the fact that we are currently experiencing a major economic catastrophe.
Here’s how Mankiw concludes:
Military and economic catastrophes are, by their nature, unpredictable. While we can’t plan on one, prudence requires that we take their possibility into account. In normal times, when we are lucky enough to enjoy peace and prosperity, the debt-to-G.D.P. ratio shouldn’t just be stable; it should be falling. That has generally been the case throughout our history, and it should become the case again as we look forward. The bottom line is that President Obama is right that sustainability is a reasonable benchmark for evaluating long-run fiscal policy. But the standard he applies when evaluating it appears too easy. It will leave us too vulnerable when the next catastrophe strikes.
While I completely agree that we should save in good times (i.e. have a falling debt to GDP ratio), we are not in good times and it’s quite likely that trying to save too much in bad times will be counterproductive. A primary reason why we want to be creditworthy is to have the ability to borrow for times like this. I simply have a hard time understanding why preparing for the next crisis should supersede adequately addressing the current one.
