Testing the rationality of price forecasts: comment

Article Abstract:

Direct tests of forecast rationality were conducted by Keane and Runkle (KR). KR's most demanding tests involving either oil prices or M1 are erroneous due to flawed integration accounting. Incorrect integration accounting resulted in trivial cointegration, improper distributional assumptions and, thus, wrong conclusions. It is concluded that KR's results do not empirically support the rational-expectations hypothesis.
