Engel Curves for Fair Trade Consumption and Development Perspectives for Producers: Evidence from Data on Real Fairtrade Purchases
基于实际购买数据估计公平贸易的恩格尔曲线，发现公平贸易需求具有高支出弹性，市场扩张依赖于进口国人均收入增长及产品多样性、可得性和质量的提升，为生产者提供了发展启示。
While Fairtrade sales have exhibited two-digit growth rates over recent decades, their capacity to become large enough to generate substantial gains for producers is still uncertain. Estimating Fairtrade Engel curves based on real purchases, this article describes how Fairtrade consumption varies with consumer characteristics and total income. Results show high expenditure elasticities for Fairtrade demand, and suggest that market expansion lies in the growth of income per capita in import countries and in an increase in the diversity, availability, and quality of products. Implications for producers are drawn from the results.
