Testing Restrictions on a Model of Japanese Meat Demand
对日本肉类需求系统模型进行准可分性、净替代性和完全替代性检验，发现鸡肉与乳牛牛肉、鸡肉与猪肉存在净互补关系，日本和牛被视为独立商品，鱼类可视为可分。
Abstract Tests for quasi‐separability, net substitutability, and perfect substitutability are developed and implemented on an almost ideal demand system model of the Japanese meat sector. The data set satisfies both symmetry and homogeneity. There is evidence of net complimentarity between chicken and dairy beef and chicken and pork. The tests indicate that Japanese Wagyu beef is considered a separate commodity to both imported beef and dairy beef. The results also indicate that fish can be treated as separable in the Japanese meat demand system.
