Abstract
The objective of this paper is to test
empirically the effect of a devaluation of a currency on the trade account of
the country, the J-curve effect, by using the trade between the U.S. and six
countries (Euro-zone, Canada, United Kingdom, Switzerland, Japan, and
Australia). A devaluation (depreciation) of the U.S. dollar is increasing the
spot exchange rate ($/FC) and increases the price of imports and reduces the
price of exports. Then, imports are falling and exports are increasing and the
trade account is improved in the long-run. In the short-run, the trade account
is deteriorated because imports are pre-arranged and continue to increase with
the higher spot rate. This J-curve hypothesis is tested by using a regression
and a VAR model, where the volatility of the real exchange rate (TOT) is
specified with a GARCH-M process. The empirical results mostly are supporting
the J-curve effect.
