Judul: Analisis Faktor Penentu Integrasi Pasar Beras di Indonesia
Abstrak: Rice is a staple food and has a strategic role in Indonesia. Therefore, the government has to maintain rice price to be stable. Rice price stabilization will be more effectively implemented on integrated markets. The objectives of this study are (1) to analyze market integration among retail rice price at provinces in Indonesia, between retail rice price at provinces in Indonesia and wholesale rice price at Cipinang Wholesale Rice Market (PIBC), and between wholesale rice price at PIBC and international rice price; (2) to analyze the impact of rice price shock on a market to other markets; and (3) to analyze the determinants of rice market integration in Indonesia. Johansen cointegration test was used to analyze market integration while impulse response and forecast error decomposition variance were used to analyze the impact of price shock. Ordinary least squares method were also used to analyze the the determinants of rice market integration in Indonesia. Result of the study shows that retail rice price among provinces is not fully integrated. Similarly, retail rice price at provinces in Indonesia and wholesale rice price at PIBC is also not fully integrated. Market integration test between wholesale rice prices at PIBC and international rice prices shows that IR-64 II rice price at PIBC had cointegration with Thailand 15 percentage broken and Vietnam 15 percentage broken,while IR-64 III rice price at PIBC only had cointegration with Thailand 15 percentage broken rice price, but not with Vietnam 15 percentage broken. Shock on a province’s rice price had directly impact on that province’s rice price itself on early period while another market had not been affected yet. Similarly, rice price variation on a market was caused by shock on the market itself rather than by other markets. The research also found that road as transportation infrastructure is positively and significantly associated with market integration, as well as rice procurement by BULOG and percapita income. Raskin distribution is also statistically significant but associated negatively.

Abstrak: The stable and affordable rice price is one of the components that well contributed to the food security in Indonesia. One of the rice problems is related to its price spread, farmer as a rice producer want to get high rice price, and the other hand consumer want to get low rice price. Government intervention, especially Bulog, is needed how to help maintain a good price for consumer and producer. But, many parties had been expected that this role was decreased. It had been showed by the price spread that increased since 1998. The objectives of this paper are to analyze the price movement of paddy and rice in the farmer, wholesaler, and consumer level, as well as the type of price spread between paddy and rice in various islands and big cities in Indonesia; analyze the factors that influence the price spread between paddy and rice; and identify the rice market integration, both spatial and vertical analysis. The quantitative approaches, especially the vector error correction model, were used to answer those objectives. From the result, it can be concluded that paddy price in the farmer level is more volatile than rice price in the consumer and wholesaler level. Moreover, the rice price in the various islands and big cities in Indonesia when Bulog’s function as LPND is more volatile than the status as Perum. But, the other way, the national paddy price is more stable when Bulog’s status as Perum. It shows that rice policy stands up for the consumers and sellers than the producers or farmers. Price spread between paddy and rice was increasing from time to time, but the price fluctuation in the Perum period is better than LPND period. There is long run relationship between total of rice purchase, total of paddy purchase, Government Purchasing Price (HPP) for rice, Government Purchasing Price (HPP) for paddy, premium oil price, international price, exchange rate and price spread of paddy and rice. Result of market integration analysis shows that retail price in 12 big rice markets, as well as wholesale price in 4 big ports in Indonesia was not fully integrated. Besides that, vertical market integration of rice in Indonesia was founded, but with asymmetric price. Response of price change in the consumer level was transmitted to the farmer level imperfectly.
