I would call this a pretty brain dead article, esp. for a Harvard Economist. Pay people to borrow money? Maybe if the negative interest rate is low enough, I can retire on the mortgage on my house. The article has other equally stupid ideas like declaring currency ending in a selected digit worthless, e.g. bills ending in 9 are worthless. Negative interest actually exists in periods of high inflation. We all know how much fun that is. Makes me want to turn in my Harvard economics degree for a refund.
