Historical and Institutional Perspectives on American Agricultural Development
重新评估了生物创新在美国农业发展中的关键作用，指出其帮助农民应对病虫害、拓展生产环境并提升生产力，同时强调联邦政府干预在控制动物传染病和保障食品安全中的必要性。
Biological innovations played a far more important role in American agricultural development than previously thought. These innovations were essential in allowing farmers to combat pests and diseases, to move the agricultural production into new environments, and to increase farm productivity. Many biological advances, especially those aimed at fighting contagious animal diseases, required unprecedented federal government interventions to overcome the free‐rider problem and to transfer new knowledge into effective public policy. Early USDA animal disease programs significantly increased productivity and trade in the livestock sector and prevented hundreds of thousands of untimely deaths in the United States from food‐borne illnesses by 1940.
