Mechanical Harvesting and the California Tomato Industry: A Simulation Analysis
基于计量经济模型的模拟分析，比较了机械收割与手工收割在不同工资水平下对加州加工番茄产业的影响，发现机械收割扩大了总就业但减少了季节性收割岗位，消费者是主要受益者。
Abstract Simulation analysis based on an econometric model was used to compare processing‐tomato industry performance with and without the development of mechanical harvesting and under differing wage scales. Expanded production under mechanical harvesting increased requirements for preharvest, seasonal and off‐season cannery, and assembly labor relative to continued hand harvest. This offset much, but not all, of the reduction in seasonal harvest labor. Employment shifted more toward jobs of higher skill and pay. Product prices were lower. Economic surplus measures suggest consumers have been the primary long‐run benefactors of mechanical harvest adoption.
