Abstract
Abstract: This study aims to analyze the value of copra exports in Indonesia before the crisis and after the crisis: The effect of foreign income and foreign prices. The data used is the annual time series of foreign income and foreign copra prices obtained from Directorate General Of Estate, Federal Reserve Economic Data, world bank and Ministry of Trade, The time period covered is 1980-2016. The Ordinary Least Squares (OLS) method was used to estimate the value of copra exports by adding a dummy variable with a value of zero for the period before the 1998 crisis and one for the period 1998-2016. The choice of the OLS method was based on the stationarity test where all variables were found to be cointegrated at the level. The results of the analysis show that only foreign income and the dummy crisis affect the value of Indonesia's copra exports. When the sample is divided in two, it is found that for the period before the crisis, foreign income and copra prices have no significant effect. For the period after the crisis, only foreign income affects the value of Indonesia's copra exports. The implication of this finding is that Indonesia can target greater copra exports to export destination countries that have relatively high economic growth rates.
