Greenspan Expresses Concerns

The nation's remarkable prosperity will be put at risk unless supply and demand are brought into balance, Federal Reserve Chairman Alan Greenspan said Monday.

Speaking at a conference on the "New Economy" sponsored by Boston College, Greenspan voiced renewed concerns that the record-setting economy was growing too rapidly given the dwindling supply of new workers and the increasing need to rely on imported goods.

Greenspan's speech was likely to strengthen the belief of many economists that the Federal Reserve will continue to raise interest rates until it sees greater evidence that the economy is slowing enough to keep inflation under control.

"Overall demand for goods and services cannot chronically exceed the underlying growth rate of supply," Greenspan said. "The expansion of demand must moderate."

Greenspan's high-caliber audience gave him a polite welcome, and even joined in a rousing chorus of Happy Birthday before he started speaking, even though some of the Internet companies represented on the floor and their high-flying stocks appeared to be just those he was targeting with his remarks.

The Fed works to achieve this moderation by increasing borrowing costs for consumers and businesses, cutting into demand for big-ticket items such as homes and autos. The central bank has already boosted interest rates four times since June with the latest increase on Feb. 2, a quarter-point boost that left the federal funds rate at 5.75 percent.

Economists are predicting the Fed will raise rates again when it next meets March 21 and many are looking for a sixth rate increase at the following meeting on May 16.

Greenspan said the Fed's efforts to slow the economy by raising the short-term interest rates that it controls are being aided by increases in long-term interest rates, which are controlled by financial markets.

He said long-term corporate borrowing costs "have risen significantly over the past two years" because of continued strong demand for new loans on the part of consumers and businesses.

Greenspan noted that the higher business borrowing costs were prompting many analysts to project that stock market gains may begin to slow as increased interest payments by businesses cut into corporate profits.

Greenspan said the central bank will be carefully monitoring developments to bring about the required movements in the economy to better balance the supply of labor and capital with demand.

"Until market forces, assisted by a vigilant Federal Reserve, effect the necessary alignment of the growth of aggregate demand with the growth of potential aggregate supply, the full benefits of innovative productivity are at risk of being undermined by financial and economic instability," he said.

Even with those threats, Greenspan said Americans are living through remarkable economic times with a strong surge in workers' productivity helping to boost incomes and keep inflation frobeing a problem. The current expansion became the longest in U.S. history at 107 months in February and this month is celebrating its ninth birthday.

"Not only has the expansion achieved record length, but it has done so with economic growth far stronger than expected," Greenspan said. "Most remarkably, inflation has remained largely subdued in the face of labor markets tighter than any we have experienced in a generation."

On Friday, the government reported that the unemployment rate edged up to 4.1 percent in February from 4 percent, which had been the lowest jobless rate in 30 years. Some analysts saw the slight uptick in the jobless rate as the first indication that the Fed's efforts to slow the economy were beginning to have an impact.
