U.S.‐Mexican Trade in Winter Vegetables and Illegal Immigration
构建了一个包含七个方程的经济计量模型，分析美国与墨西哥在冬季西红柿贸易和农业劳动力非法移民之间的相互影响，发现两国经济状况及移民与贸易政策均会影响被抓获的非法移民数量。
Abstract This paper presents an integrated approach to U.S.‐Mexican trade in a labor‐intensive commodity (fresh winter tomatoes) and illegal immigration of agricultural labor. A seven‐equation econometric model is developed that includes excess demand (U.S. import) and supply (Mexican export) equations for fresh winter tomatoes, U.S. demand and Mexican supply equations for apprehensible individuals, intercountry price and wage relationship equations, and a U.S. Border Patrol apprehension effort equation. The empirical results indicate that both U.S. and Mexico economic conditions affect the number of apprehended illegal Mexican aliens. The results also indicate that immigration and trade policies affect apprehensions.
