The Price Is a Blight

The rich world, and especially the euro zone, risks harmfully low inflation.

Abandoning Reserve
That danger is less acute in the United States than in the euro area largely because the Fed is more proactive than the ECB. It surprised the markets in September by sustaining quantitative easing at its present pace of $85 billion of asset-purchases a month, rather than starting to curb it. A study by economists at the Federal Reserve, published last week, has fuelled speculation that it may keep interest rates at rock bottom even longer by lowering the level of unemployment at which it will consider rate increases from the current 6.5 percent.

By contrast, the euro area looks increasingly vulnerable to a slide into deflation. Although the region emerged this spring from a painfully protracted double-dip recession, the recovery is expected to be a feeble one. GDP will fall by 0.4 percent this year and rise by only 1.1 percent in 2014, according to forecasts from the European Commission published on November 5.

Such weak growth is unlikely to overcome the forces pushing inflation down. Output will remain well below its full potential next year, estimates the commission; all that idle capacity acts as a drag on prices. Unemployment across the euro area will stay stuck at a woefully high 12.2 percent, which will keep wages down. The strength of the euro will also exert a downward pull. It has been trading this week at $1.35, more than 5 percent higher than a year ago; on a trade-weighted basis it is 8 percent higher.

Very low inflation in the euro zone makes it much more difficult for uncompetitive countries, predominantly in southern Europe, to regain lost ground. Workers tend to resist nominal cuts in pay more fiercely than they do the subtler erosion of their income through inflation. If inflation in the countries with which the weak economies trade is high, they can improve their competitiveness simply by keeping their rate lower. That is in essence how Germany gained a big edge in the first decade of the euro.

But with overall inflation so low, peripheral countries must instead adjust through outright deflation or something close to it, meaning a freeze or absolute cuts in wages. Already, in September, when euro-wide inflation was 1.1 percent, prices were falling by 1 percent in Greece. They were flat in Ireland and rising by just 0.3 percent in Portugal.

A sustained period of deflation would be particularly hard on the euro zone’s periphery, weighed down by debt. Cyprus, Ireland, Portugal and Spain have high public and private debt; Greece and Italy have high public debt. When prices are falling, debt, which is fixed in nominal terms, becomes more onerous in real terms. Higher inflation, in contrast, makes escaping heavy debt much less burdensome.

Central banks have had to move beyond past orthodoxies in order to coax a modest recovery from the ruins of the financial crisis. Now, to avoid the blight of stagnating or falling prices, they may have to venture still further into unconventional territory.
