Economists in Glass Houses
April 7, 2015
For many economists, the chicken and egg question is, which came first, consumption or production? What drives growth? Let’s continue with our series on debt, in which I have been contrasting my views with those of Paul Krugman.
Our differences aside, what Paul and I readily agree on is that the solution to our current economic dilemma is more and higher-quality growth. There is nothing like 5–7% nominal growth to tackle a problem of too much debt. And if the real growth is 3–4%, then so much better, as employment and wages will rise as well. But what drives growth? That’s actually a complex question with multiple answers. There is simply no one magic policy that you can pursue that is sufficient in and of itself to create growth. I would think Krugman and I also would agree that the stimulation of growth requires a whole bunch of smart policies, and we would likely agree on what some of those policies should be. Our policy disagreement stems from our differing views on fundamental economic questions as opposed to any simplistic analysis of today’s numbers.
Last week we looked at some of the differences between Paul’s presuppositions and mine, presuppositions that most people might think of as being more philosophical than analytical in nature. That letter generated more response than any other letter I’ve written in a very long time. Most of the comments were really very thoughtful, and I appreciate them. We’re going to look at one reply...
