Integrated Regressors and Tests of the Permanent Income Hypothesis
NBER Working Paper No. 2359 (Also Reprint No. r1039)
We use recent research on estimation and testing in the presence of unit roots to argue that Hall's (1978) t and F tests of whether consumption is predicted by lagged income, or by lags of consumption beyond the first, are asymptotically valid. A Monte Carlo experiment suggests that the asymptotic t and F distributions provide a good approximation to the actual finite sample distribution.
