Financial bailouts, stimulus spending, and lower revenues during the Great Recession have resulted in some of the highest public debt ratios seen in advanced economies in the past forty years. Recent debates have centered on the pace at which to pay down this debt, with few questions being asked about whether the debt needs to be paid down in the first place.
A radical solution for high debt is to do nothing at all—just live with it. Indeed, from a welfare economics perspective—abstracting from real world problems such as rollover risk—this would be optimal. We explore this issue in our recent work. While there are some countries where clearly debt needs to be brought down, there are others that are in a more comfortable position to fund themselves at exceptionally low interest rates, and that could indeed simply live with their debt (allowing their debt ratio to decline through growth or windfall revenues).
