Abstract

This study analyzes the structure of food demand in urban China based on the most recent household expenditure survey data. Consumer food preferences are represented by an Exact Affine Stone Index (EASI) demand model, which accounts for unobserved consumer heterogeneity and allows for arbitrary Engel curve shapes. Further, we account for unobserved province-level heterogeneity in food preferences via province fixed-effects. Our findings indicate that seafood, fruit, and vegetables are income and expenditure elastic, while commodities such as grains and eggs are less than unitary elastic.
