This study examines the convergence rate of mean reversion by estimating the half-lives of sectoral real exchange rates using an extensive product price panel for Japan (with the USA as the numéraire). We find that the half-lives of sectoral real exchange rates are remarkably distorted when the grouped half-life is measured inappropriately and the cross-sectional dependence and potential trend breaks are ignored. After taking account of these problems, the bias-corrected half-life for all goods is as low as 3.00 years, close to the bottom of the consensus view of 3 to 5 years. Moreover, the bias-corrected half-life of mean reversion is 2.40 years for traded goods, and only approximately half that for non-traded goods. Finally, our findings also support the view that small-sample bias correction is critical for half-life estimations.
