신선육과 가공육으로 분리된 육류의 수요체계 분석

Abstract

This study aims to analyze the demand system of Korean meat products with which we can take into account fresh meat and processed meat separately by using a non-linear Almost Ideal Demand System (AIDS) model. The results show that individual characteristics, seasonality, and livestock disease outbreak have different effects on the demand for fresh meat and processed meat. Elderly people seem to consume more fresh meat rather than processed meat and there is also seasonal variation in processed meat consumption. The outbreak of HPAI has negative impacts on the consumption of fresh chicken, while the expenditure share of processed chicken increased after the outbreak. Finally, the cross-price elasticity estimates show a complementary relationship between processed beef and processed chicken. The domestic fresh beef demand is estimated to be elastic with respect to the price of fresh pork, while the demand for processed pork is elastic with respect to the price of domestic fresh beef price.
