This study examines in detail the experiences of three countries that
have in recent years operated exchange rate systems of "crawling bands,"
similar in spirit to the target zones that the author has recommended in
the past. Williamson compares the succcessful experiences of 3 countries
that have operated crawling bands with 15 similar countries and
concludes that the crawling band exchange-rate policy has been an
important element in their success. The study includes a manual for
managing crawling bands.
