This paper examines the performance of the unbiasedness test of ration
ality using survey data by accounting for measurement errors associate
d with the survey expectations, and also the generated regressor probl
em arising from the quantitative expectations having been generated fr
om an auxiliary equation. It is shown that ignoring the generated regr
essor problem can yield incorrect coefficient estimates and markedly l
arger standard error estimates, which could lead to an incorrect accep
tance of a false null hypothesis.
