Hog-Round Marketing, Seed Quality, and Government Policy: Institutional Change in U.S. Cotton Production, 1920–1960
研究了1928至1960年间美国棉花产量翻三倍、质量显著提升的变革，分析了一品种社区运动和史密斯-多克西法案等政府项目如何催化生物技术革命，并展示了阿克洛夫柠檬模型和早期产品周期中鼓励知识产权扩散的实例。
Between 1928 and 1960 U.S. cotton production experienced a revolution with average yields roughly tripling while the quality of the crop increased significantly. This article analyzes the key institutional and scientific developments that facilitated the revolution in biological technologies, pointing to the importance of two government programs—the one-variety community movement and the Smith-Doxey Act—as catalysts for change. The story displays two phenomena germane to the recent literature: an important real-world example of Akerlof's lemons model and a case in which inventors, during an early phase of the product cycle, encouraged consumers to copy and disseminate their intellectual property.We would like to thank Shelby Baker, Dick Bassett, Fred Bourland, J.
