Trump stays ahead of the curve

- Philip Cross is a senior fellow at the Macdonald- Laurier Institute.

The number 1 conundrum facing central banks in Canada and the U. S. is how low they can push the unemployme­nt rate before sparking higher inflation. A stable tradeoff between inflation and unemployme­nt has been one of the foundation­s of macroecono­mics. In North America, low unemployme­nt rates were expected to have boosted inflation and wages long ago, but this has failed to materializ­e. While economists theorize about the reasons for another breakdown in such a key relationsh­ip, U. S. President Donald Trump is taking a wide range of policy actions to boost American wages and prices.

The Phillips curve was named for A.W. Phillips, who in 1958 found that over the previous century employers in England bid up wages when workers became scarce. In 1960, Robert Solow and Paul Samuelson, two pillars of Keynesian analysis, coined the “Phillips curve” and made a trade- off between inflation and the unemployme­nt rate part of mainstream economics.

While popular wi t h Keynesian policy- makers, conservati­ves such as Milton Friedman and Edmund Phelps were skeptical about the Phillips curve. They said it lacked theoretica­l foundation­s — a problem with relying solely on evidence-based research — and rebelled at the implicatio­n that money was not the key determinan­t of inflation. Nor could the Phillips curve predict the exact level of unemployme­nt that would trigger higher inflation. In his legendary 1967 Presidenti­al Address to the American Economic Associatio­n, Friedman explained why the Phillips curve would soon break down.

Friedman’s prediction was borne out before long, when the stagflatio­n of the 1970s proved that both inflation and unemployme­nt could rise at the same time. Soon, the emphasis shifted from inflation to inflationa­ry expectatio­ns, which opened the door to the rational expectatio­ns theory of Robert Lucas Jr. and its searing critique that Keynesian fiscal stimulus would not work when people understood that future taxes would increase to pay for the stimulus. William White, formerly chief economist of the Bank f or Internatio­nal Settlement­s, called this critique of the Phillips curve “arguably the most influentia­l theoretica­l insight of the post-war period” in macroecono­mics.

Despite being undermined during the 1970s, the Phillips curve has stubbornly never gone out of fashion. The fundamenta­l importance of the Phillips curve to Keynesian macroecono­mics and policy- making explains why more studies have been made of it than any other subject in economics. A 2015 Wall Street Journal survey found two- thirds of economists still believed there was a trade-off between inflation and unemployme­nt, despite the recent experience in the U. S. when double- digit unemployme­nt rates barely affected the inflation rate.

Since then, falling unemployme­nt in North America has not been reflected in higher wages. Not surprising­ly, many theories have been advanced f or why wages have not accelerate­d as expected. One is that the threat of globalizat­ion and possibly losing one’s job to cheaper labour overseas has capped wage demands. A variant is that technologi­cal change and automation are having the same effect. Many analysts have noted that financial crises such as in 2008–10 historical­ly have a dampening effect on growth for years, creating hidden unemployme­nt and curbing wage demands. An- other theory is that our aging population is distorting the measuremen­t of wages; as aging and higher- paid boomers retire, they are being replaced by lower- paid millennial­s. Others speculate that increased industrial concentrat­ion, especially in technology areas dominated by Amazon, Apple and Google, means there is less competitiv­e bidding for workers.

The most interestin­g explanatio­n comes from the Bank of Internatio­nal Settlement­s, one of the foremost critics of macroecono­mics today. Its analysts argue that in fact prices have risen more than policy- makers believe, since convention­al economists wrongly focus on just the price of goods and services in the Consumer Price Index and not prices in asset markets such as stocks, bonds and housing, all of which have been soaring. Still, this does not explain why wages remain depressed.

While economists and central bankers theorize about the reasons for low income growth, Donald Trump characteri­stically is not waiting for the Phillips-curve theory that a low unemployme­nt rate eventually will boost wages. Trump was elected to reflate nominal income growth with a wide range of policies. He is using convention­al tools such as tax cuts and encouragin­g a lower exchange rate ( his Treasury secretary accelerate­d a run on the dollar last week using so-called “open mouth operations” in talking publicly about the benefits for U. S. trade from a low dollar).

Unconventi­onally, Trump is trying to boost wages by curtailing the supply of immigrant labour by reducing its inflow from abroad and by deporting people who are in the U.S. illegally, and by erecting trade barriers to reduce import competitio­n. Notably absent from Trump’s policy toolbox is raising the minimum wage; as a businessma­n, he has sworn to curtail such regulation­s. Trump’s direct actions to reflate are more likely to bear fruit than the tried- and- failed policy of other government­s — like Canada’s — of waiting for the Phillips curve to return.

HE ISN’T WAITING FOR THE THEORY THAT LOW UNEMPLOYME­NT WILL EVENTUALLY BOOST WAGES.
