H. Baghestani et Am. Kianian, ON THE RATIONALITY OF UNITED-STATES MACROECONOMIC FORECASTS - EVIDENCE FROM A PANEL OF PROFESSIONAL FORECASTERS, Applied economics, 25(7), 1993, pp. 869-878
ASA-NBER survey data is used to check the rationality of US macroecono
mic forecasts. It is found that of 75 forecast series examined, 51 are
biased, 25 are both unbiased and efficient and only two pass the null
hypothesis of orthogonality. This calls into question the validity of
rational expectations hypothesis.
