Is It Structural or Cyclical Unemployment?

The Economist magazine is asking whether there has been an increase in America’s structural unemployment. If the answer is yes then macroeconomic policy may be limited in how much it can do to lower unemployment. Thus, even if the Fed further stabilized aggregate demand the benefits for the unemployed and the broader economy may be muted. My own view has been that both structural and cyclical unemployment have been important in this economic cycle. On one hand, the the rapid productivity gains in 2009 (they are down in 2010) point to increased structural unemployment, a point recently made by David Altig. On the other hand, there is evidence consistent with a slowdown in aggregate demand which points to increased cyclical unemployment.

So how important are these two forms of unemployment? Justin Weidner and John C. Williams of the San Francisco Fed have a note that helps answer this question. In the note the authors look at the various measures of the output gap and via Okun’s Law, the implied natural rate of unemployment. Now the natural rate of unemployment is the sum of frictional unemployment and structural unemployment. Frictional unemployment, which is a function of search costs, most likely hasn’t changed that much. Thus, any change in the natural rate of unemployment is probably coming from changes in structural unemployment. Below are unemployment tables constructed from the different measures of the output gap discussed in this note. The first table shows the implied natural rate of unemployment and the second one shows the implied cyclical rate of unemployment (i.e. actual unemployment rate minus the natural rate of unemployment).

What this table indicates is that since 2008:Q4 cyclical unemployment has been hovering around 3.0% while the natural rate has been growing steadily and now is around 6.8%. This data, if correct, suggests that folks like me who call on the Fed to do more in terms of stabilizing aggregate demand should realize the limits of macroeconomic policy. Still, providing a stable monetary and aggregate demand enironment in which the structural adjustments can take place should not be overlooked.

  1. Structural unemployment is real and is here to stay. Even those economists who re beginning to recognize the problem vastly underestimate the ultimate impact. It is not just about a "skill mismatch." It is ultimately going to be about a total lack of demand for skills (and workers). It is something unprecidented and it is caused by advancing technology. And ,no, it is NOT the same thing that has been going on for decades. Technology is moving faster and faster. In the next couple of decades will will see a staggering level of progress.

    For an excellent overview of this problem, check out this book (available as a free PDF): The Lights in the Tunnel: Automation, Accelerating Technology and the Economy of the Future. (http://www.thelightsinthetunnel.com).

    If there were a textbook on this issue of technological unemployment and where it will lead, this book is it. I wish every economist would take a break from data analysis and READ THIS BOOK.
