The dynamics of intensive cultivation
研究了土地质量均匀时，农产品需求增加如何导致更集约的耕种方式，并揭示多重均衡可能带来的问题，对理解农业租金理论有用。
If land is uniform in quality, an increase in the demand for agricultural goods leads to the use of more intensive cultivation methods. Though Ricardo saw no difficulties in the intensification process, their existence is revealed by the possible occurrence of multiple equilibria. A general theory of intensive rent makes use of a formal parallel between land and labour to transfer properties of single-product systems without land to agricultural systems.
