U.S. economy revved up, but it's probably temporary

According to the article, GDP rose at a 2.5% annual pace in the first quarter of the year, driven largely by a pick-up in consumer spending. Consumer spending, which alone accounts for about two thirds of GDP, rose at a 3.2% annual pace, the fastest pace since the end of 2010. However, as significant as it may seems, there is a chance that it will just be temporary. The reason is that consumers funded their spending in part by saving less. Americans saved an average of 2.6% of their disposable income in the first quarter, down from 4.7% at the end of 2012. Moreover, people have been spending more on services than goods due to the fact that this March was also the coldest since 2002, a weather pattern that boosted the demand for heating. Thus, economists have a solid ground in suspecting that the increase in GDP is only temporary.
