The US economy shrank at an annual rate of 1 percent in the spring, a better-than-expected showing and more evidence that the recession is drawing to a close. The Commerce Department's new estimate for the gross domestic product was unchanged from the initial figure it released last month. The drop, while representing a record fourth consecutive decline, was far smaller than the previous two quarters. It also was stronger than the 1.5 percent decline that private economists expected. The report Thursday found that businesses slashed their inventories more than first reported and cut back more sharply on investment in new plants and equipment. But those reductions were offset by revisions that showed smaller dips in consumer spending, exports and housing construction. The 1 percent rate of decline in the April-June quarter followed decreases of 6.4 percent in the first quarter and 5.4 percent in the final three months of 2008, the sharpest back-to-back declines in a half-century. The four straight quarterly declines in GDP mark the first time that has occurred on government records that date to 1947. The recession that began in December 2007 is the longest since World War II, and the deepest in terms of the drop in the GDP, which is down 3.9 percent from its previous peak. Many analysts think that the $787 billion economic stimulus plan and the Cash for Clunkers program to boost car purchases will lift GDP growth to around 2 percent in third quarter.
