英文文献摘要：
This paper explores the welfare changes as a result of changes in prices and quantities of Colorado labeled apples relative to domestically produced apples, using equilibrium displacement model with two-regions: Colorado State and the rest of the United States. The results showed that in the short run producers would lose $300, while in the long run producers would increase supply to capture $263,000 in increased surplus.

摘要本文以科罗拉多州和美国其他地区为研究对象，利用均衡位移模型，探讨了科罗拉多州标签苹果相对于国内生产苹果的价格和数量变化所导致的福利变化。结果显示，在短期内，生产商将损失300美元，而在长期内，生产商将增加供应以获得26.3万美元的盈余。
