Cover Story: We provide new analytical results for the implementation of the Hausman specification test statistic in a standard panel data model. We show that the test statistic is unreliable in a finite sample if the variance of the Random Effects estimator is computed on the basis of the OLS estimation of the quasi-demeaned model rather than the conventional and direct implementation of the Feasible Generalized Least Squares. The difference between the two Hausman statistics computed under the two methods can be substantial and even lead to opposite conclusions for the test. Furthermore, we point out that the vast majority of econometric software implements, by default, the Hausman test using the unreliable statistic. We propose to supplement the test outcomes that are provided to circumvent this issue.
