GDP, GDI, and Trading Gains: An Alternative View
从经济统计角度论证贸易收益（实际国内总收入与实际国内生产总值之差）可能是一种统计假象，若选择特定的贸易平衡缩减指数，贸易收益便会消失。
This note argues that, from an economic‐statistical point of view, trading gains, as difference between real gross domestic income and real gross domestic product, may be considered as a statistical artifact; that is, trading gains vanish if a particular deflator for the trade balance is chosen.
