FellP20180308_low  Cartoonist Gary Varvel: Trump's tariff can of worms


U.S. capitalism has a real problem: there don’t seem to be enough workers to keep the economy growing.

And it has another problem: capitalists themselves are to blame for the missing workers.

As is clear from the chart above, the employment-population ratio (the blue line) has collapsed from a high of 64.4 in 2000 to 59 in 2014 (and had risen to only 60.1 by the end of 2017).* During the same period, the average real incomes of the bottom 90 percent of Americans have stagnated—barely increasing from $37,541 to $37,886.

That should be indicator that the problem is on the demand side, that employers’ demand for workers’ labor power has decreased, and not the supply side, that workers are choosing to drop out of the labor force.

But, as I explained back in 2015, that hasn’t stopped mainstream economists from blaming workers themselves—especially women and young people, for being unwilling to work and turning instead to public assistance programs and raising children and being distracted by social media and digital technologies, as well as Baby-Boomers, who are choosing to retire instead of continuing to work.

So, which is it?

Katharine G. Abraham and Melissa S. Kearney have just completed a study in which they review the available evidence and their conclusion could not be clearer:

labor demand factors, in particular trade and the penetration of robots into the labor market, are the most important drivers of observed within-group declines in employment.


Over the course of the past two decades, U.S. capitalists have decided both to increase trade with China (through outsourcing jobs and importing commodities) and to replace workers with robots and other forms of automation (it is estimated that each robot installed displaces something on the order of 5-6 workers).

That’s the main reason the employment-population ratio has declined so precipitously and that workers’ wages have stagnated in recent years.

Clearly, U.S. capitalists have been remarkably successful at increasing their profits. But they have just as spectacularly failed the vast majority of people who continue to be forced to have the freedom to work for them.


*The Bureau of Labor Statistics defines the employment-population ratio as the ratio of total civilian employment to the 16-and-over civilian noninstitutional population. Simply put, it is the portion of the population that is employed. Thus, for example, in 2000, the total number of civilian employees in the United States was 136.9 million and the figure for the civilian noninstitutional population was 212.6 million. By 2014, the civilian noninstitutional population had grown to 247.9 million but the total number of workers had risen to only 146.3 million. The employment-population ratio differs from both the unemployment rate (the number of unemployed divided by the civilian labor force) and the labor force participation rate (the share of the 16-and-over civilian noninstitutional population either working or looking for work).


René Magritte, “La clef des champs” (1936)

Plenty of illusions are being shattered these days, such as the idea that a successful recovery from the worst economic downturn since the Great Depression would keep the incumbents in power. A combination of lost jobs, stagnant wages, and soaring inequality put an end to that illusion. Much the same has happened to American Exceptionalism.

Noah Smith has just discovered another shattered illusion: the independence of supply and demand.


Mainstream economists generally think about the world in terms of supply and demand—at both the micro and macro levels: supply and demand in the market for oranges or labor (which determine the equilibrium price and quantity), as well as aggregate supply and demand for the economy as a whole (which determine the equilibrium level of prices and output). Perhaps even more important, they think about supply and demand as acting independently of one another: a shift in supply or demand in individual markets (which lead to changes in equilibrium prices and quantities) as well as “shocks” to aggregate supply or demand in macro models (which determine changes in the equilibrium level of prices and output). The presumption is that a shift in demand (at the level of individual markets or the economy as a whole) does not cause a shift in supply (at either level), or vice versa.*


As it turns out, the independence of supply and demand is just an illusion.

As I wrote back in 2009, it’s quite possible that at the micro level—for example, in the case of the labor market—both supply and demand are determined by something else, such as the accumulation of capital.

Thus. . .if the accumulation of capital leads to rightward shifts in both the demand for and supply of labor, wages may not increase (and quite possibly will decrease).

Therefore, supply and demand in individual markets aren’t necessarily independent.

And then, in 2013, I discussed the illusion of the independence of aggregate supply and demand.

In terms of the mainstream model, the collapse of aggregate demand leading to the crash of 2007-08 has also affected the aggregate supply of the economy—thereby shattering the illusion of the independence of the two sides of the macroeconomy. As the authors put it, “a significant portion of the recent damage to the supply side of the economy plausibly was endogenous to the weakness in aggregate demand—contrary to the conventional view that policymakers must simply accommodate themselves to aggregate supply conditions.”

Not only does the destruction of a significant portion of the future growth potential of the U.S. economy challenge the model mainstream economists use to analyze the macroeconomy and to formulate policy; it also forces us to question the rationality of a set of economic arrangements in which trillions of dollars of potential wealth (which might then be used to improve lives for the majority of the population) are sacrificed at the altar of keeping things pretty much as they are.

It represents the indictment both of an academic discipline and of economic system.

So, Smith is right: the shattering of the illusion of the independence of supply and demand means the way mainstream economists teach basic economics is fundamentally wrong.

What he forgets to mention, however, is that an economic system that is governed by supply and demand that are not independent of one another—and thus is subject to considerable instability on a regular basis, with the costs being shouldered by those who can least afford it—is also open to question.

Perhaps Tuesday’s results will serve notice that the time for challenging mainstream economics and the economic and social system celebrated by mainstream economists has finally arrived.


*There can, of course, be simultaneous shifts in supply and demand but the shifts themselves are considered independent of one another.

And then there’s Nouriel Roubini’s story:

Severe unrest in the Middle East has historically been a source of oil-price spikes. . .

Even before the recent Middle East political shocks, oil prices had risen above $80-$90 a barrel, an increase driven not only by energy-thirsty emerging-market economies, but also by non-fundamental factors: a wall of liquidity chasing assets and commodities in emerging markets, owing to near-zero interest rates and quantitative easing in advanced economies; momentum and herding behavior; and limited and inelastic oil supplies. If the threat of supply disruptions spreads beyond Libya, even the mere risk of lower output may sharply increase the “fear premium” via precautionary stockpiling of oil by investors and final users.

What we have are two different ways of telling the supply-and-demand story of oil prices: the latter based on an actual belief in the story, the former based on how oil prices actually get set.
