Cambodian rice marketing system and causality in prices : 캄보디아 쌀의 유통체계 및 가격 변동 분석

다국어 초록 (Multilingual Abstract)

Rice is Cambodia’s principal food, its major crop, and, in times of peace, its most important export commodity. Cambodia achieved its first surplus rice in 1995 and surpluses have been recorded in every subsequent year. However, there are still many Cambodian people who lack access to this basic necessity due to insufficient purchasing power (rice being sold in Thailand and Vietnam for higher prices), and poor transport and marketing systems. Under the market economic policy, rice marketing is entrusted almost entirely in the hand of the private sector expertise and investment. And indeed, Cambodia has the latent potential to be an exporter of niche and high-quality varieties of agricultural products, competitive capacity and economic efficiency. It is clear that rice industry and marketing system in this country have still many problems. Therefore, the Royal Government of Cambodia, particularly the CMAFF, has to positively consider and solve these problems and sooner compile in order to maximize agriculture output and improve property value.
In this thesis, it will be also examined the causality relationships between wholesale and retail rice prices and between domestic market and world market rice prices, based on the time series data compiled from two commodities of Phka Kagney and Neang Menh rice prices (domestic market) and white rice 100% Grade B: FOB price in Thailand (world market) for the monthly period of January 1998 through December 2003. Sims’ causality model which is based on Granger’s definition of causality was utilized.
Analysis based on the panel data indicated the absence of causality between the wholesale and retail prices of both rices. On the other hand, the results revealed a two-way causation relationship between domestic market and world market in the case of wholesale prices. But, it was single direction causality from retail price to world price, except that test-2 of Neang Menh retail prices in the case 2-month time lag has a bilateral causality. However, it could not lead to precise conclusions, though suggested a somewhat stronger link between domestic market and world market. New theoretical and empirical studies are needed to improve our understanding of causality test.
