This study analyzes the cropping system and the income of greenhouse farms in chonnam province, and seeks an efficient farm plan to increase their income. Since the middle of 1980's the demand for fresh vegetables and the size of greenhouse horticulture farms have been expanding rapidly along with the general standard of living. The area of the greenhouse horticulture which accounted for 31% of the total area of the vegetable planted in 1993, has increased to 54% in 1998. Vegetables such as strawberries, watermelons, tomatoes, and peppers are crops in which farmers can make a large income. But Most of the farmers have problems of inefficient management as well as capital shortage, so they are exposed to risks. Methods such as maximin, minimax, QP, MOTAD, Target MOTAD are used to manage risks and offer efficient farm plans. According to the specific situation they are faced, farmers can make a decision with results concluded by each method.

Even though the red pepper is one of the most important seasoning vegetables in Korea, the volume of usage of domestic red pepper has shrunk due to decrease in consumption. Thus, researchers and government officers need to seek for solutions to extend usage of domestic red pepper of food processing industry which consumes considerable amount of it. The purpose of this paper is to analyze the factors of the usage of domestic red pepper in food processing companies using cross-tabulation analysis and multiple regression model and to find the implications for promoting the usage of domestic red pepper. The results of studies present that specific characteristics of food processing companies affect the usage of domestic red pepper, including size of sales, shape of company, food product processed by company, human organization for purchase of food material, registered trademark, and support of government. This study also suggests that government needs to offer more supporting programs to sauce industry and improve the system of program to promote the usage of domestic red pepper.

This paper analyzes the time-series variation of rice price for the period of 1981 to 2000. Rice is a major staple and has a large influence on Korea economy and the farming business. Of the total farm production, rice accounted for 30% in 1995 and accounted for 56% of the total size of the cultivated acreage. The domestic price of rice is about three times as high as imported rice price, and the domestic producers are effected to get severe damage if rice market is open completely. The fluctuation of rice price has been enlarged since the reformation of government food policy in 1993. It is necessary to study a characteristic of past and present rice price Methods such as ARIMA and ARCH are used to investigate a fluctuation of rice price and offer an accurate forecast. As a result of analysis, ARIMA(2, 1, 0)(2, 1, 2)_(12), ARIMA(2, 1, 1) and GARCH-M(1, 1) are concluded as good models.

Red pepper acreage response is very important for policy decision regarding red pepper production as well as mitigation of the high dependency of imported red pepper. Previous studies based on Nerlovian model resulted in spurious regression problem which can be overcome by using cointegration analysis and error correction model (ECM). This study attempts to investigate the influence of own price and related products`` prices on the acreage response of red pepper by using ECM. The results show that long-run elasticities are higher than short-run elasticities. Also own price elasticity of red pepper and cross price elasticities are high in the long-run. The results imply that government should focus on the factors that affect the long-run price elasticity and formulate the policies that ensure the profitable price to the producers.
