Abstract

Economic growth and rising incomes have significantly increased protein intake through meat consumption. This trend, combined with the rapid Westernization of diets and increased consumption of processed foods and dining out, has led to per capita meat consumption surpassing rice consumption in Korea. Understanding the dynamics of meat demand is critical, especially given that demographics are expected to further impact consumption patterns. This study analyzes the meat demand system by focusing on the estimation of own-price and cross-price elasticities and, specifically, the effect of changes in household size. We employ the Quadratic Almost Ideal Demand System (QUAIDS) model using consumer expenditure survey data for fresh meat products. Our findings reveal that consumer demand for both domestic and imported beef is own-price elastic, while demand for domestic pork is own-price inelastic. Generally, a substitution relationship exists among meats consumed domestically. However, results suggest that the substitutability is lower than conventionally assumed because domestic and imported beef are perceived as distinct goods due to quality and price differences. Furthermore, the consumer response (substitution effect) remains relatively insensitive to price changes between domestic pork and imported beef/pork. All meats demonstrate positive expenditure elasticity, with beef higher than pork. One- and two-person households were found to exhibit the largest own-price elasticity and the smallest expenditure elasticity for domestic beef and pork. As these smaller households grow, continuous policy attention is needed to sustain domestic meat consumption.
