In 1969 Klein founded Wharton Econometric Forecasting Associates or WEFA (now IHS Global Insight), launching the econometric forecasting industry in the United States. Among his clients were General Electric Company, IBM, and Bethlehem Steel Corporation. He was the initiator of, and an active research leader in their LINK project, a consortium of model builders from many countries, which was also mentioned in his Nobel citation. The aim was to produce the world's first global economic model, linking Models of many of the world's countries so that the effect of changes in the economy of one country are reflected in the other. LINK, which is now operated by the United Nations, is still meeting regularly, most recently in October 2009 in Bangkok.
