英文文献摘要：
The use of contracts for producing and marketing agricultural commodities has become nearly universal in some sectors. Two factors are most frequently cited as being responsible for the use of agricultural contracts. The first, a demand-side factor, is the development of strong consumer preferences for specific qualities. The second, a supply-side factor, is technological change. In this paper, we use a principal agent framework to model how consumer demand and technology enter into a firm's decision to use contracts or the cash market.

在某些部门，使用合同来生产和销售农业商品已几乎成为普遍现象。使用农业合同最常提到的是两个因素。首先是需求方面的因素，即消费者对特定品质的强烈偏好的发展。第二个是供给方面的因素，即技术变革。在本文中，我们使用一个委托代理框架来建模消费者需求和技术如何进入一个公司的决策使用契约或现金市场。
