According to the latest ranking, the most accurate forecaster is Gene Huang of FedEx, pushing Gary Thayer of A.G. Edwards to second place. Resler and Hoffman keep third and fourth place, respectively. The median forecast falls from 6th to 10th. The lanterne rouge continues to be James Smith of the University of North Carolina. At 2.6%, his forecast for 2008:Q1 was as inaccurate as usual.
The naive forecast, which is equal to the growth rate observed during the previous quarter, would have been spot-on this time, since GDP grew by 0.6% in both Q4 and Q1. Historically, however, it has performed worse than any forecaster but one.
Only Edward Leamer of UCLA Anderson Forecast was right on the mark. The predictions of 38 of the 52 forecasters were within one percentage point of the truth.
