英文文献：Exchange Rates In International Commodity Models: The Common Currency Question Revisited
英文文献作者：Meyers, William H.
英文文献摘要：
This paper clarifies the difference between estimating supply and demand equations for individual countries in national currencies or converting to common currency prior to estimation. The appropriate procedure for a pooled cross-country time-series estimation model depends upon the cross-sectional constraints and whether nominal or real values are used.
