The serial correlation-robust median-unbiased estimator yields a cross-country average of half-lives of deviations from parity of about eight years, with the REER of several countries displaying permanent deviations from parity. The paper analyzes integration of Africa into world trade. The high-yield spread as a predictor of real economic activity is also examined UR - http://elibrary.imf.org/view/IMF024/03378-9781589062030/03378-9781589062030/03378-9781589062030.xml UR - http://www.imfbookstore.org/IMFORG/9781589062030 ER -
