The U.S. economy will begin to show signs of improvement in 2011 as major indicators such as housing and consumer spending begin to improve by mid-2011, according to an annual outlook report from Wells Fargo. Consumer spending, which is one of the main components of GDP growth, will turn positive, even if it is not as strong as during the pre-recession period, the report said. “Consumer spending, representing the majority of aggregate demand in the economy, will benefit from a streak of positive, yes positive, employment reports by mid-2011, lower unemployment rates and rising real personal income,” the report added.
