Abstract

IndonesianTulisan ini mencoba melihat integrasi pasar beras dengan menggunakan uji kointegrasi (cointegration test). Pendugaan kointegrasi pada bivariate sistem dilakukan dengan memperlakukan setiap peubah sebagai peubah endogenous dan exogenous secara bergantian (dua arah). Pada analisis ini digunakan model Engle dan Granger yang disebut Cointegrating Regression Durbin Watson (CRDW) dan Augmented Dickey Fuller (ADF). Selanjutnya analisis sebab-akibat Granger diterapkan pada pasar-pasar yang berkointegrasi untuk menentukan pasar sentral dan pasar regional. Hasil pengujian stationarity menunjukkan bahwa pada umumnya harga beras stationar pada order 1, sedangkan hasil uji kointegrasi memperlihatkan bahwa tidak semua pasar yang letaknya berdekatan berintegrasi satu sama lain. Dari 56 kombinasi hanya terdapat 26 kombinasi pasar yang berkointegrasi. Data harga beras yang digunakan adalah harga perdagangan besar dari tahun 1979-1995. Hasil pengujian ini menunjukkan bahwa kebijakan kontrol harga yang dilaksanakan oleh BULOG tidak dapat mencegah terjadinya segmentasi pasar.EnglishThis article analyzes integration of rice markets using co integration test. The co integration bivariate system were estimated in both directions. Cointegration analysis based on the Engle and Granger model, namely CRDW and ADF, is applied. Granger (cause) analysis applied to co integrated markets, to find central and regional markets. Test results show that most of rice prices are stationary of order 1. It is concluded that there seems to be long run relationships between markets which are relatively close to each other. Percentage of cointegrated market for rice is 46 percent out of 56 combinations. This high cointegration mainly due to marketing system of rice which is strongly controlled by the government. Hence rice price is subject to a controlled trade regime and floor/ceiling price. Rice prices is represented by monthly wholesale price. The periode covered in this study is 1979-1995. It was concluded that BULOG's Policies in controlling rice market to avoid market segmented did not work as expected.

Abstract

Maintaining rice selfsufficiency in the condition of fiscal austerity can be conducted through technological generation, efficiency improvement, or input subsidy reduction. The objectives of this study is to asses the impact of price liberalization of Urea, TSP, and other chemical fertilizer (KCI and ZA) to the application of those fertilizer and national rice production. The study used the combination of cross-section (five regions) and time series data of 15 years (1979-1993). There are four empirical models under considerations in this study, i.e: rice production function, and demand function of Urea, TSP, and other chemical fertilizers. The system equations of rice production and fertilizer demand functions are estimated simultaneously in order to have an efficient parameter estimates. The research findings indicated that fertilizer price liberalization had positive impact on the structural application of those fertilizers, in which the use of Urea and TSP decline and the use of other chemical fertilizer increases. The structural change of those fertilizer application have positive impact on yield and national rice production, at the magnitude of 5,1 percent. In order to maintain rice productivity (selfsufficiency) and efficient use of national resources, the reduction of Urea and TSP subsidy can be conducted in a faster rate than those ZA's and KCI's For larger rice production improvement, technological breakthrough is really needed in conjunction with managerial skill improvement of the farmers.
