Wharton Economic Forecasting Associates (WEFA) was a world-leading Economics forecasting and consulting organisation founded by Nobel Prize winner Lawrence Klein.

WEFA's LINK project, to produce the world's first global macroeconomic model, was mentioned in his citation for the Economic Sciences in 1980.

WEFA was a spinoff of the Wharton School of the University of Pennsylvania, where Klein taught. WEFA was merged with DRI (formerly Data Resources Inc) in 2001 to form Global Insight.
