The consensus expectation among economists on Wall Street and at the Federal Reserve is that consumer spending will begin to increase at a more rapid pace in the coming months. This expectation is based upon several factors, but the two most commonly cited are the improvements in the labor market and the drop in energy prices.

Historically, rapid job growth and lower gas prices have put more money in the consumer's pocket, allowing her to spend more freely. This time around, however, the spending gains have not been so robust.
