World Governments Cut Spending

The world’s rich countries are now conducting a dangerous experiment. They are repeating an economic policy out of the 1930s — starting to cut spending and raise taxes before a recovery is assured — and hoping today’s situation is different enough to assure a different outcome.

In effect, policy makers are betting that the private sector can make up for the withdrawal of stimulus over the next couple of years. If they’re right, they will have made a head start on closing their enormous budget deficits. If they’re wrong, they may set off a vicious new cycle, in which public spending cuts weaken the world economy and beget new private spending cuts.

On Tuesday, pessimism seemed the better bet. Stocks fell around the world, over worries about economic growth.

Longer term, though, it’s still impossible to know which prediction will turn out to be right. You can find good evidence to support either one.

The private sector in many rich countries has continued to grow at a fairly good clip in recent months. In the United States, wages, total hours worked, industrial production and corporate profits have all risen significantly. And unlike in the 1930s, developing countries are now big enough that their growth can lift other countries’ economies.

On the other hand, the most recent economic numbers have offered some reason for worry, and the coming fiscal tightening in this country won’t be much smaller than the 1930s version. From 1936 to 1938, when the Roosevelt administration believed that the Great Depression was largely over, tax increases and spending declines combined to equal 5 percent of gross domestic product.

Back then, however, European governments were raising their spending in the run-up to World War II. This time, almost the entire world will be withdrawing its stimulus at once. From 2009 to 2011, the tightening in the United States will equal 4.6 percent of G.D.P., according to the International Monetary Fund. In Britain, even before taking into account the recently announced budget cuts, it was set to equal 2.5 percent. Worldwide, it will equal a little more than 2 percent of total output.
