Land Abundance, Interest/Profit Rates, and Nineteenth-Century American and British Technology
研究发现19世纪美国经济各部门资本密集度低于英国，源于美国土地丰裕导致更高的利息/利润率，并借助李嘉图线性模型分析其相互关系。
Virtually all sectors of the nineteenth-century American economy were less capital-intensive than their British counterparts. This resulted from persistently higher American interest/profit rates, due in turn to American land abundance. The paper adduces the evidence in support of these propositions, and explores their interrelationships through the use of a linear model inspired by the writings of David Ricardo.
