In a recent interview with Dollars & Sense Bob Pollin says about the debate with Reinhart and Rogoff on the relation between public debt and economic growth:
"The heart of the matter is that when you’re borrowing money you can use it for good things or bad things. You can be doing it in the midst of a recession. If we’re going to invest in green technologies to reduce carbon emissions, that’s good.
We also need to ask: what is the interest rate at which the government is borrowing? The U.S. government’s debt servicing today—how much we have to pay in interest as a share of government expenditures—is actually at a historic low, even though the borrowing has been at a historic high. The answer obviously is because the interest rate is so low. When you’re in an economic crisis and you want to stimulate the economy by spending more, does the central bank have the capacity to maintain a low interest rate? In the United States, the answer is yes. In the UK, the answer is yes. Germany, yes. In the rest of Europe, no. If you can borrow at 0%, go for it. If you have to borrow at 9%, that’s a completely different world."Read the full interview here.
