Marginal Analysis of Income Mobility Effects by Income Source with an Application to the Agricultural Policy Mix
利用Shorrocks流动性指数按收入来源分解的新方法，识别各收入组成部分边际变化对农场收入流动性的影响，并以苏格兰农业为例，发现市场支持与直接支付之间的收入中性调整并未降低相对农场收入的波动性。
Abstract The Note makes novel use of a decomposition of the Shorrocks mobility index by income source to identify the impact on farm income mobility of a marginal change in each component of income. An empirical application shows that a revenue‐neutral change in the balance of agricultural protection between market‐based support and direct payments would not have reduced the variability of relative farm incomes in Scottish agriculture.
