Demand for dairy products in Mexico
研究了墨西哥国内及进口乳制品的需求，计算价格和收入弹性，发现液态奶需求对价格最敏感，而脱脂奶粉需求缺乏弹性，汇率是影响所有乳制品进口的最重要变量。
Abstract Mexico is the world's largest importer of non‐fat dry milk (NFDM) and imports of cheese, fluid milk, and whey have increased rapidly in the past four years. In the wake of GATT and the NAFTA, as well as recent economic developments in Mexico, world dairy markets will be affected as a result of changes in the Mexican dairy sector. The study analyzes both domestic and import demand for dairy products in Mexico to determine price and income elasticities as well as import elasticities. The results indicate that the demand for fluid milk is the most responsive to price changes and NFDM demand is inelastic with respect to its own price. There is little subtitution between fluid milk and non‐fat dry milk, although fluid milk is relatively elastic, which suggests the existence of other substitutes for fluid milk. Estimation of import demand equations reveal similar trends in response to price changes, but income elasticity of imports was highest for fluid milk which suggests that Mexico will import possibly more fluid than dry milk as incomes rise. The exchange rate was the most significant variable influencing all dairy product imports.
