국내 주요 냉동수산물의 가격 변동성의 비대칭성에 관한 연구

Abstract

The production of popular fish species, which are important in terms of supply in the Korea fishing industry, which is continuously decreasing. In particular, the recently decrease in fishery resources, due to illegal fishing, overfishing by Chinese fishing vessels, and climate change has been causing supply imbalances and price fluctuations. seafood is highly prone to price volatility due to its characteristic of variable production(seasonal item) and the impossibility of planned production. because seafood prices have a more complex and dependent structure than general time series. These factors act as negative problems in terms of stable supply of marine products in korea. Fluctuations in seafood prices increase the risk of producers and workers in related industries due to future uncertainty, making income unstable, and leading to a decrease in purchasing power for consumers. As a result, high price volatility of marine products reduces the welfare of the people who consume marine products as well as the welfare of the entire fishing industry. Therefore, the purpose of this study is to investigate the price volatility and asymmetry of volatility of cutlassfish, mackerel, and squid, which are designated as price stability management items among the top 10 fish species that require active price management by the government. This information can be used as reference material to efficiently promote policies related to seafood prices, such as purchasing seafood and stockpiling projects. Additionally, from a responsive perspective, it can be said to be important in that it provides appropriate information to understand the price fluctuation characteristics of commodity assets formed in the market. Lastly, if a way to stabilize the income of producers is sought, and if consumers have sufficient information about price changes, price uncertainty can be resolved, which can have a positive impact on the equality of consumers' purchasing power.
