Josh Bivens: Nowhere Close: The Long March from Here to Full Employment

By Josh Bivens

The last official business cycle peak occurred in December 2007. After that, the economy entered 18 months of virtual freefall—with job losses averaging more than 750,000 per month for the worst six-month stretch. The official end of the recession was June 2009—and some have recently declared full recovery has been reached in the 54 months since, as 2013 per capita GDP finally exceed its pre-recession levels. However, for the very large majority of Americans who rely on paid employment for the vast majority of their income, recovery likely still feels very far off. And they’re right—by any reasonable definition the United States is far from having reached a full recovery. That’s because simply clawing back to the per capita income level that prevailed before the start of the Great Recession is far too low a bar to clear to declare mission accomplished on recovery. The reason for this is simple: Joblessness (and the sapping of bargaining power that accompanies its rise even for still-employed workers) rises whenever a gap develops between the economy’s underlying productive potential and aggregate demand for goods and services. The intuition here is simple: A given number of customers’ demands can be satisfied with fewer people as each incumbent worker becomes more productive, and each new potential worker (new graduates, for example) seeking to enter the workforce will only be employed if there is extra consumer demand for what he or she produces. So, demand has to rise in line with the economy’s productive potential in order to keep joblessness from rising.

The End of Endless Growth?

In my assigned role as the (anti) Thomas Robert Bannister (Malthus), I thought I would return to the blog after a far-too-long hiatus with this post to share recent work. Note that this work is the other main area of research beyond my dissertation interest of the role of energy revolutions in economic history. I'll return to that one given recent posts here, but for now:

This work asks many questions, the fundamental one being do we really need to radically change behaviours to attain zero growth, or, what do we really mean by zero growth?

The conditional answer is that our world can achieve zero total growth (in the expected lifetimes of some of us) while still having per-capita GDP growth. The key, wearing my anti-Malthus hat, is population-conditional. To introduce the topic, here is a figure from my model that shows GDP levels peak at about 2080. I think that is a very radical outcome, with many implications. It is based on several forecasts, including the current UN low population forecast.

The only other forecast I'll mention for now is that the per-capita real GDP increases through the forecast period. The second-largest caveat is the large forecast error bands; I'll simply note that at least I show them. Most climate models (of which this is a member) eschew error estimates. I can do so because I use empirical forecasting methods.

So, peak GDP levels in 2080 with continuing real per-capita output growth (forever). A surprising result certainly to me. The largest caveat in this method is the population curve you believe we are on. I'll discuss that in a future post. For now, just enjoy that a (credible?) model exists that allows the zero-gowth crowd and the lift-the-poor crowd to coexist on the same model path.

I will monitor questions. This will be my EEA talk; just a heads-up for those who wish to stockpile (potatoes and other) ammunition.
