This study presents a study of the elasticity of the foreign trade toward the foreign exchange rate of Czech Republic, Slovak Republic, Hungary, Poland, Slovenia and Bulgaria for the period from 1992 to 2000. As a method for evaluation of the dependency between the export, import and the foreign exchange rate is used the spectral analysis, especially the bi-spectral analysis.
For this purpose are made a review and generalization of the econometric studies of the elasticity of the foreign trade in the last decades, analysis of the opportunities of the bi-specter for presenting the elasticity, solutions of information problems, connected with the current empirical study.
Determined is a specific revealing of the elasticity of the foreign trade of the countries from Central and Easter Europe. First, determined is presence of income effect in the revealing of the dependency, i.e. low elasticity of the export and high elasticity of the import. Second, determined is that the delay in the revealing of the elasticity varies between 2 and 8 months depending on the type of transaction and the country.
