FXstreet.com (Barcelona) - The Sandy storm may result in a shortage of economic output by $25 billion in Q4, says Bloomberg, citing Gregory Daco, a U.S. economist at IHS Global Insight in Lexington, Massachusetts. Bloomberg notes: "He said that could reduce the fourth quarter pace of growth to between 1 percent and 1.5 percent, from the firm’s earlier estimate of 1.6 percent."
