By Moran Zhang - The U.S. economy grew at a 2.4 percent annualized rate in the fourth quarter, the Commerce Department said Friday, revising down its initial estimate of a 3.2 percent increase in the nation's economic performance.
The drop in fourth-quarter gross domestic product growth was largely due to a smaller-than-expected boost from Americans buying bit-ticket items such as autos.
Consumer spending, which accounts for 70 percent of the U.S. economy, slowed to a 2.6 percent rise from 3.3 percent in the third quarter. Export, inventory accumulation and government spending also contributed to the downward revision in GDP.
