As economy develops, the average level of living is rasing. But the tremendous gap in income within and between sectors is a source of economic and social concern in Korea. The average gap ratio between Agricultural and Non-agricultural sector during the period of 1970∼1990 was estimated by 3.7. Thus the gap between these two sectors will increase further. Closing the gap may serve as a rationalizing objective of national economic development. The redistribution policy of income will have a useful influence on economic development and also can contribute to an increased rate of economic growth. The income redistribution policy as well farm income enhancement policy is needed for reducing the income disparity between sectors.

農家所得의 構造와 增大政策方向

Fram income includes agriculatural income and off-farm income in rural areas. The proportion of agricultural income in total farm income was 32.8percent in 1982. Average farm household income raised from agricultural source has not been enough to meet total farm household expenses. Agricultural income can meet farm household expenses by 93.0percent in 1982. The maintenance of small scale farming in Korea will cause long term problems for agricultural development. It will be impossible to increase agricultural income if the average farm size remains 1ha. Farms of such small scale will eventually limit the supply of agricultural products, and the income disparity between rural and urban areas will widen. There will be some throughts of policy alternatives for the improvement of farm income. The first alternative will be the policy to increase agricultural income through an increased production of cash crops and a modernization of agricultural market structure, including improvement of storage facilities and processing facilities, provision of rural infrastructure. The second will be the policy to increase off-farm income through the development of rural infrastructure, improvement of rural merketing services, development of a modernized credit system in rural areas, improvement of education and vocational trining in rural areas, investment for research and technical assistance, and development of rural industrial estates for rural industrialization. Under the present land law and the small farming system it is necessary to develop the source of off-farm income in rural areas to meet the deficit of household living expenses. The thrid alternateve will be the structural policy to increase the average farm size to increase agricultural income. The traditional small-scale farming method has become a bottleneck to further productivity gains. There is struong possibility to create rational enlarged farms if the employment poortunity in non-farm sector is expanded and the structural policies are implemented.

During the period of January 1984-December 1988 the chance of increases in Korean cattle farm prices was 47 percent and that of decreases was 53 percent. While the chance of increases in beef retail prices was 47 percent and that of decreases was 53 precent. During the period when the Korean cattle farm prices increased the chance of increases in beef retail price was 75 percent and that of decreases was 25 percent. When the cattle farm prices decreased the -chance of increases in beef retail price was 22 percent and that of decreases was 78 percent. The monthly average rate of increases in cattle farm prices was 4.2 percent and that of decreases was -3.4 percent. The monthly average rate of increases in beef retail prices was 3.2 percent and that of decreases was -2.1 percent. Over long term cattle farm prices and beef retail prices did move together. During most of the latter part of the year, cattle farm prices moved out ahead of beef retail prices but narrowed again toward the very end of the year. The variability in cattle farm prices was greater relatively than at retail.

糧穀管理制度의 問題占과 改善方向

The dual-price policy for rice and barley was implemented to achieve the multiple objectives such as increase of foodgrain production and farm income, stabilization of general price level, and enhancement of urban household welfare. The negative differential between the government sale price and the cost of sale has been widening since implementation of the policy. The scale of government foodgrain operation also has been expanding rapidly since 1970. In order to stabilize market price, the government tried to increase the share of government foodgrain in the market. As a result, the government's market share of foodgrain increased to 40-50 percent and the seasonal fluctuation of rice price decreased considerably. Due to the foodgrain dual-price policy and the expanded scale of government operation, the fiscal deficits in Grain Management Special Accounts has been increasing steadily. The total deficits in Grain Management Special Accounts amounted to 1,248 billion Won in 1982. In order to improve present government foodgrain operation system and to reduce the deficits caused by the dual-price system, the government purchase prices of rice and barley should increase at a proper rate based on production costs while the government selling price should increase at a higher rate than purchase price. As a consequence, the government selling price and the cost of sale would be equal by 1986. The government purchase and sale price should be determined according to the market equlilibrium price. The government purchases grains during harvest time at market equlilibrium price or little higher than the price and releases at shortage periods at going market price or lower than the price. Through this government foodgrain market operations the price of foodgrains would be stabilized and seasonal price fluctuation would be minimized in the short run. Allowance of an appropriate rate of seasonal variation in market price would induce farmers to retain their rice for later sales as well as encourage middleman to invest in storage facilities. This is consistent with the government' long-run foodgrain policy which is to eliminate government intervention and stimulate market principles in the food market. Under the present foodgrain operation, the government purchases foodgrains from farmers during or after harvest time and releases them during shortage periods when grain prices are high. It would be called short-term stabilization scheme of supply and demand. The purpose of this is to minimize seasonal price fluctuations within the given stabilization range at all times throughout the year. In order to reduce the scale of government foodgrain operation substantially, government should allow seasonal fluctuations considerably. It will be hard to stabilize year-to-year supply with short-term adjustment scheme. Year-to-year unbalances of grain supply and demand are mostly due to unusual good or bad harvest. Therefore, it is recommended that long-term foodgrain security reserves program be introduced with supplement of the present short-term buffer stock program. The scales of government foodgrain operation should be enough to secure supply target of foodgrain and to achieve the goal of price stabilization. If stabilization target of foodgrain price is given in line with general price stabilization level, then a specific target band could be set up around the long-term trend of per capita consumption of foodgrains. There is no need to correct this situation by reserve transaction during the year when actual supply of foodgrain falls within this band. Only when supply of foodgrain exceeds or falls short of the target band government should intervene in the grain market. And by this gap between the target band and actual supply of food grain the scale of government foodgrain operation and the reserve capacities also could be determined. It will be more effective to establish regional foodgrain security reserves system rather than that in only single country.
