Data for the economic uncertainty index

Description of this data for the article 'Economic Uncertainty, Precautionary Motive and the Money Demand Function'. Data: The index of economic uncertainty is calculated by using the optimal form of the optimal economic uncertainty index, as described in the article, Table 1, that is obtained by computer simulation using the grid search algorithm (outlined in the article's Appendix A).《经济不确定性、预防性动机与货币需求函数》一文配套数据集说明： 数据集说明：本研究中的经济不确定性指数，采用本文表1所述的最优经济不确定性指数形式，通过网格搜索算法（grid search algorithm）开展计算机模拟计算所得，该算法的具体细节详见本文附录A。
