As a consequence, the real exchange rate
(measured as the ratio of the prices of tradables to nontradables) began to gradually appreciate
(that is, the ratio fell). Several studies have attempted to estimate the extent of the overvaluation
of the Asian currencies in early 1997. Although methodologies and data sources differ somewhat,
most analyses suggest that currencies became modestly overvalued, especially between 1994 and
1996.3 Our own estimates suggest overvaluation of about 20% in Thailand, Indonesia, Malaysia and the Philippines, and about 10% in Korea.
