Economists surveyed right before the Collapse of 2008
Lecture 3 within “Modern Economic Issues”, by Robert Whaples, is titled “Economists’ View of the Future”. The course seems to have been published early in 2008 and perhaps recorded in 2007, since many statistics from 2006 are cited. One of the lecturer’s aims seems to have been to present listeners with a comprehensive view of thought by economists around the U.S. Nearly every lecture presents at least two sides of every issue and oftentimes refers to surveys of American economists. Whaples himself conducted a survey of economists and their predictions about the years 2008 through 2018 right before giving these talks.
Whaples starts by pointing out that for most of the field’s existence economists have erroneously been predicting a flat standard of living, thus entirely missing the growth in real personal income that has been the main story since the Industrial Revolution. Classical economics predicts that new ideas or methods may lead to a temporary improvement in per-capita wealth but that the result of this new wealth will be larger families and more children surviving to adulthood. These new workers will compete with each other and the result will be a market wage that is near the subsistence level. Worldwide GDP may grow but population will expand so that the average person is living with only the bare necessities of life.
This prediction has failed to come true, according to Whaples, primarily because (1) the pace of technological change for the last 200 years or so has been so rapid that humans have not had a chance to have enough kids to soak up all of the benefits, (2) the rising wages of women have discouraged many from spending a lot of time out of the workforce and therefore fertility has been lower. Other economists have gone farther, claiming that the larger the population the more opportunities there are for new ideas to be developed, which will make everyone richer per capita, not poorer.
Given this backdrop of pessimism and continually being proved wrong by events, what did the economists surveyed circa 2007 predict about 2008 through 2018 in the United States? Nearly all predicted the strong growth that had prevailed in the 1990s and through 2006 to continue virtually unabated. The only real debate was among those who through the strong growth was permanent and those who thought there would be reversion towards a less spectacular level of growth. Of those interviewed by Whaples, not a single economist, apparently, predicted the Collapse of 2008 and subsequent stagnation!
So next time that an economist shows up in an Op-Ed column or on TV to explain why lackluster growth is the new normal for the U.S. remember that, not too long ago, probably the same person was predicting a very bullish 2008 through 2018 and that the growth of 1991-2006 was the “new normal”.
