As the Fed’s continued tightening tends to suppress growth in emerging economies, US labor market may not be as strong as recent reports suggest.

US experienced strong job growth in June, when the economy created 222,000 net new jobs, which exceeded analyst expectations.

At the Federal Reserve, the jobs report boosted confidence US economy is on the track for new rate hikes in the fall. As the unemployment rate is barely 4.4 percent, the Fed expects that the US economy can cope with further tightening. Yet, despite the solid performance, not everything is in place for sustained job growth.

In June, some jobs were fueled by temporary drivers. The June gain of 35,000 jobs in state and local government was preceded by a loss of 8,000 jobs in the sector in May. Other June gains reflect school districts’ new hires for the fall. Moreover, the retail sector added over 8,000 net new jobs; but only after losing almost 80,000 jobs between February and May, as a result of the ongoing shift to online retailing.

Much job growth was due to hiring in healthcare, social assistance and local governments, which are coping with America’s aging and ailing population.

Usually, when unemployment is low, employers tend to increase wages to attract new workers and keep existing ones. That’s not the case today. Instead, some of the biggest job gains are taking place in lower-wage sectors, such as healthcare and temporary workers, which keeps wage growth down.

US recovery also suffers from structural constraints. The unemployment rate is relatively lowest among whites (3.8 percent) and Asians (3.6 percent), higher among Hispanics (4.8 percent), twice as high for blacks (7.1 percent) and far higher for youths (13.3 percent).

Moreover, the labor force participation rate — the number of people who are employed or actively looking for work — peaked at 67 percent in the early 2000s, but is less than 63 percent today.

Unlike labor force participation rate, the employment-population ratio is not as affected by seasonal variations or short-term fluctuation. In the US, it used to be almost 75 percent in the early 2000s; but today it is barely 60 percent as fewer young Americans are looking for work and baby boomers are retiring.

The current Fed believes in the so-called Phillips curve, a historically inverse relationship between rates of unemployment and corresponding rates of inflation. In this view, decreased unemployment goes hand in hand with higher rates of inflation.

End of Phillips curve

Consequently, as US unemployment rate is now only 4.4 percent, that should correlate with progressively rising inflation. And yet, the reality seems to be precisely the reverse. Until early 2017, unemployment rate did steadily decrease, while hourly earnings climbed close to 2.9 percent. But in the past few months, unemployment rate has remained around 4.4 percent, whereas hourly earnings have decreased to 2.4 percent.

Historically, a short-run trade-off between unemployment and inflation reflected the postwar Keynesian era when the rates climbed from 2 percent in the 1950s peaking at 20 percent in early 80s. In the past three decades, the rates have shrunk to zero. Yet, even though job growth is no longer accompanied with wage growth, Yellen continues to rely on the Phillips curve to guide monetary policy.

Instead of new hikes in the fall, the Fed would need a rethink. If the theory associated with the current policy path is untenable, it cannot provide appropriate guidance. In fact, new data is likely to reflect soft inflation and lingering wage growth. As a result, spring 2018 is likely to witness the removal of the Phillips curve from its protruding seat at the Fed.

In international view, a rethink is also vital. A single-minded focus on rate hikes that are likely to result in much collateral damage in emerging markets is dangerous when those emerging economies account for most of global growth prospects.
