Out of the Economic Wilderness

Things go in stages. I remember a time when I put a lot of gunk on my hair so it would stand up straight in what was known as a flat top. Then I had a wave. The Air Force preferred something closer to my scalp. Post-Air Force, I let it grow for about four years. My hair had a lot of stages. Today, well, there are a few spots missing here and there.

And so it is with economic thought. I had the luck of taking a wonderful course in the history of economic thought at the University of North Carolina. A main goal of that course was to see that economic thinking evolves over time and very much reflects the natures and problems of a given time or place. This recognition of the temporary nature of economic ideas gives one some confidence that whatever the prevailing wisdom might be today, it is sure to be supplanted by something else in the near future.

As a graying economist, I have seen lots of change during my career. When I was at the University of Arizona getting a masters degree (while stationed in Tucson with the Air Force), the bravado of Keynesians was revealed in their confidence about the accuracy of forecasts of Keynesian models. Keynes had reacted to the failure of previous so-called Classical Models to explain the Great Depression. But it was the eventual failures of Keynesian models that led to a host of competing theories by unreconstructed Keynesians, monetarists, and supply-siders.

Today, we have a mish-mash of models with elements of each of those schools of thought. But there is a very clear and common thread among them that focuses on the apparent short-run instability of advanced industrial (rich) nations. We argue among ourselves about the proper policy in a given country at a given time but the argument is framed within a short-run model that encourages us to focus on moving the economy back to short-run equilibrium. If inflation is running too hot, we try to bring its temperature back down. If the economy is languishing with high unemployment and slow growth, we give it a pep pill. The pill might be designed to alter short-run demand or supply but the focus is always on overcoming an undesirable stage of an economic cycle.

This bouncing around has gone on in the USA at least since the early 1960s when John F. Kennedy announced his famous tax cut that would move us out of a recession. Since then, we have handed the policy ball back and forth between quelling rapid inflation and stimulating recessed spending. One byproduct of this has been a dizzy economic experience. Another offshoot is a national debt that reaches for the sky. There have been a few times when the debt as a share of the economy abated somewhat, but mostly it rises and then rises more. Today, it approaches 100% of the size of the US economy and promises to go even higher than that.

I think the dizziness plus debt is wearing us out. Worse is that it is becoming more and more obvious that this preoccupation with the economic cycle is distracting us from recognizing and treating what has become the new scourge of industrial nations. Today, we debate whether the economy is too strong or too weak. Today, we debate whether or not to have stimulative monetary policy. We argue about the stimulative impact of rebuilding the nation’s infrastructure. Imagine all those workers paving during the day and spending at night! 

But the truth is that short-run policy never seems to accomplish anything as we careen from recession to expansion back to recession. And worse than that is that the experience of industrial nations has changed. Whether this change was brought about by industrialization or by globalization, the result is that we are weakened by modernity. Our ability to grow is at risk. Our main economic challenge has gone from trying to reduce the amplitudes of economic cycles to raising our long-run economic growth path. Last week I used the example of a long distance runner. Let’s try it again. You want to win the marathon. To run 26 miles at a fast enough pace to win, you don’t swallow a handful of sugar. You train hard. You build your wind capacity and your muscles.

We are familiar with the difference between short-run and long-run policies. While the richer nations have been toying with cyclical policies, the poor developing countries knew they could catch up only if they focused on long-run structural issues like energy, transportation, legal systems, and so on. Before they could provide adequate incomes and opportunities for their citizens, they had to build a modern infrastructure. Now it is the industrial countries that need to rebuild to meet the challenges of the day. We should replace our short-term focus with longer-term ideas.

What does that entail? The remedies should mirror the problems. Everyone seems to acknowledge that modern competition has reduced the demand for workers in the US and in other rich countries. Despite the fact that the US unemployment rate is very low, we acknowledge that too many people have dropped out of the labor force, taken jobs beneath their skill levels, or work part-time when they prefer 40 hours per week. This is clearly not a short-term issue especially when we know that technology is bringing robots on that might be smarter and prettier than your average macro professor.

This labor supply challenge is constantly on our minds but we process the information with old and worn-out models of the short-run. We continue to ask for more of the same policy gruel – juice up the money supply or give the middle-class a tax break. But we are not in a recession and we don’t need policies that cause the national debt to grow even more. What we need is to reorient the way we think. 

Tending the economic cycle does not create more sustainable economic growth. Economic growth is the salve that soothes but economic growth requires an understanding of how to compete in a high- tech world that wants to replace human hearts with robot brains.

We had to figure out how to evolve from an agricultural to an industrial economy. The transition was not pretty but we had to quit thinking about wooden plows and mules and focus on tractors. Now it is time to figure out how to move from the tractor to the driver-less, sun-powered robot. Arguments about traditional monetary and fiscal policy while creating mountains of debt, are not going to help. Where do we find someone to lead us out of the wilderness? Who understands that in the long-run we are not dead?
