Abstract-The aim of this research was to examine the interdependence between import price, exchange rate and national income. The data analysis method used was structural vector autoregressive (svar). The data used in this research was quarterly data from 1997.3 through 2013.4. The analysis was conducted on the impulse response function (IFRS) and forecast error variance decompositions (FEDVs) to determine the effect of exchange rate to import price and national income. The results show that exchange rate shock has positive effect on import price and has negative effect on national income. Furthermore, FEDVs analysis show that the variations of import price were largely determined by the import price, and the exchange rate variations were largely determined by the exchange rate itself. Meanwhile, the variations in national income were largely determined by the exchange rate variable.
