WASHINGTON (AP) — Superstorm Sandy will end up causing about $20 billion in property damages and $10 billion to $30 billion more in lost business, according to IHS Global Insight, a forecasting firm.

In the long run, the devastation the storm inflicted on New York City and other parts of the Northeast will barely nick the U.S. economy. That's the view of economists who say a slightly slower economy in coming weeks will likely be matched by reconstruction and repairs that will contribute to growth over time.

The short-term blow to the economy, though, could subtract about 0.6 percentage point from U.S. economic growth in the October-December quarter, IHS says. Retailers, airlines and home construction firms will likely lose some business.
