The Distribution of Gains from Technological Advance When Input Quality Varies
基于伊利诺伊州玉米生产技术的实证证据，研究投入品（土地）质量依赖型与独立型技术对产量提升的不同影响，并分析这些差异如何影响不同土地质量地区从技术采用中获得的经济剩余分配。
Abstract Empirical evidence about new corn production technology in Illinois supports the hypothesis that yield‐ and output‐enhancing effects vary depending on whether technology is input (here, land) quality‐dependent or independent. In turn, these differences affect the distribution of economic surplus from technology adoption across geographic regions with varying land quality. A competitive, market‐clearing model for a traded commodity is used to estimate the gains in economic surplus from technological advance.
