| Tiivistelmä: | Rogoff (Journal of Economic Literature 1996;34;647-668) describes the "remarkable consensus" of 3-5 year half-lives of purchasing power parity deviations among studies using long-horizon data. These studies, however, focus on rejections of unit roots in real exchange rates and do not use appropriate techniques to measure persistence. The authors' half-life estimates explicitly account for serial correlation, sampling uncertainty and, most importantly, small sample bias. |
