Farm income, population and farmland prices: a relative information approach
用基于熵的信息方法分析农田价值与城市压力或农场收入的关系，发现人口信息有用，但农田价值变化与收入分布变化关联更强，且存在区域和时间差异，对公平和效率有政策含义。
This paper uses an entropy-based information approach to determine if farmland values are more closely associated with urban pressure or farm income. The basic question is: how much information on changes in farm real estate values is contained in changes in population versus changes in returns to production agriculture? Results suggest population is informative, but changes in farmland values are more strongly associated with changes in the distribution of returns. However, this relationship is not true for every region nor does it hold over time, as for some regions and time periods changes in population are more informative. Results have policy implications for both equity and efficiency. , Oxford University Press.
