NEW YORK (Reuters) - The U.S. economy is on track to expand at a 4.0 percent annualized pace in the third quarter with inventory investment contributing 1.12 percentage points to growth, the Atlanta Federal Reserve’s GDP Now forecast model showed on Thursday.

Last Friday, the government said its first reading on the gross domestic product in the second quarter was a 2.6 percent growth pace, which was 0.2 point below Atlanta Fed’s final estimate.
