Financing the Deficit (More Feldstein) by Krugman

Now, this is almost an accounting identity, so by itself the figure doesn’t tell you which side is driving the action. But we know the answer to that question from other evidence. For one thing, we know that most of that surge in the private sector surplus reflects the collapse of the housing bubble, and that most of the surge in the public deficit reflected automatic stabilizers. For another, we know that if government deficits were crowding out private spending, we should have seen rising interest rates; what we actually saw was falling rates. 

So there isn’t any puzzle here, except the puzzle of people who are puzzled. I really don’t understand how Marty Feldstein can look at these facts and conclude that the only way to explain low interest rates is to imagine that the Fed is imposing massive market distortions.
