EXPORTERS' MARKET POWER IN AGRICULTURAL IMPORT MARKETS IN KOREA 31
Yang, Seung-Ryong; Lee, Won-Jin.
Korea relies more than 70 percent of food supply on a limited number of exporting counties. If the suppliers possess market power, the food security matters. This study tested whether the major exporting countries of corn and wheat have power of determining market prices and enjoy oligopolistic profit in Korea. The empirical results indicate that Korea shows a high degree of import loyalty toward U.S. products. It is evident that the U.S. and Australia have market power in the wheat market, while no distinct power is detected in the corn market. The result for the corn market seems to reflect the severe price competition between the two major exporters, the U.S. and China. It is also shown that the launch of the WTO does not significantly change the...

HETEROSKEDASTICITY IN CROP YIELD MODELS 31
Yang, Seung-Ryong; Koo, Won W.; Wilson, William W..
This study examines three alternative models of correcting for heteroskedasticity in wheat yield: the time trend variance, the GARCH, and an econometric model that includes the potential sources of heteroskedasticity. Nonnested test results suggest that modeling the sources of heteroskedasticity is the preferred procedure. Including potential sources of heteroskedasticity as explanatory variables removed the heteroskedasticity in the sample wheat yields. The results also suggest that the GARCH specification is a promising model of correcting for heteroskedasticity when the sources cannot be identified. The time trend variance model alone may misspecify the true variance structure.

JAPANESE MEAT IMPORT DEMAND ESTIMATION WITH THE SOURCE DIFFERENTIATED AIDS MODEL 31
Yang, Seung-Ryong; Koo, Won W..
A source differentiated AIDS model is specified to estimate Japanese meat import demand. Block separability and product aggregation are rejected at conventional levels of significance. The model with the block substitutability restriction explains more than 95% of data variation. The empirical results indicate that the U.S. has the largest potential for beef exports to Japan. Taiwan is in a strong position in the pork market, and Thailand and China are strong in the poultry market. The U.S. competes with Canada and Taiwan in the pork market, but the competition between Taiwan and European countries is the strongest in the market. The U.S. competes with Thailand in the poultry market, where the U.S. is the most vulnerable.

THE MINIMUM SEMI-VARIANCE HEDGE FOR FOOD MANUFACTURERS IN KOREA 31
Lee, Sang-Hak; Yang, Seung-Ryong.
This paper derives downside risk minimizing hedge ratios for Korean food manufacturers who face commodity price risks and exchange rate risk simultaneously. The results show that the minimum semivariance hedge (MSVH) effectively reduces risks. The MSVH rule is evidently more efficient than the conventional minimum variance hedge.
