This study investigates the casual relationship between kimchi imports from China, prices of napa cabbage, dried red pepper, garlic, and onion in Korea considering the increase trend of kimchi imports from China. To analyze the level of relative explanation power between kimchi imports and prices of raw materials for kimchi, this paper utilizes the Geweke(1982) method. Furthermore, we also adapt the Directed Acyclic Graph method to capture the contemporaneous causation. While kimchi imports granger cause napa cabbage price, napa cabbage price leads kimchi imports based on the contemporaneous causation concept. Kimchi imports also granger cause prices of dried red pepper and garlic. And this granger causations’ explanation levels on bivariate linear relationship are very high. Our results imply that kimchi imports from China have an impact on kimchi producers and consumers as well as producers for raw materials of kimchi in Korea. In turn, the government should develop the general policy to maintain stability of supply and demand for kimchi’s raw materials.
