Impact of world oil price shock on domestic rice price (cointegration analysis)

Abstract

Rice is a substantial strategic and food comodity in Indonesia and also in some countries in the world, particularly in Asia. Therefore, the stability of rice price and the availability should be maintained, especially rice is also known as unstable commodity. Starting in 1994, Indonesia became a net importer of rice commodity, then, Indonesia‟s rice market is allegedly integrated with the world‟s rice market. Consequently, any changes or shock in the world‟s rice market, which is one of its shocks caused by world oil price shock, will affect the domestic rice market. The objectives of this study are: (1) to analyze factors that influence the domestic rice price, (2) to analyze the effect of changes on the world oil price shocks to the domestic rice price. The applicable method for this study is vector error correction model (VECM) with analysis tools are IRF, FEVD, and pass-through. The estimation results indicate that there is a cointegration in the models studied. In the short-term, factors (variables) that affect the domestic rice price are the price of imported rice, domestic rice price, and the price of crude oil. Besides, in the long run, factors (variables) that affect the domestic rice price are the price of imported rice, world rice price, and production rice. The variables that largely influence the domestic rice price are world rice price and price of imported rice. On the other hand, a variable that slightly affect is the total factor productivity (TFP).
