Willingness to contract versus opportunity to contract: a case study in Kenya's French bean export market
研究了肯尼亚法国豆市场中农户签约意愿与签约机会的系统性差异，发现低成本生产者的特征与签约机会并不总是一致，且市场内外农户对买方可靠性的重视程度不同，暗示合同执行不完善可能影响参与。
Abstract We characterize systematic differences in willingness and opportunity to contract for farmers in and out of the French bean supply market in Kenya. We find that the factors associated with being a low cost producer do not always align with the factors correlated with opportunity to contract. We also find that farmers in and out of the market differ on average in the premiums they place on buyer reliability, which suggests that imperfect contract enforcement could impact participation in French bean contracting.
