CONSISTENT TRADE POLICY AGGREGATION*
提出与实证工作两大目标（保持实际收入和实际经济活动量）一致的贸易政策加总方法，并应用于印度，发现标准非理论加总方法将印度实际收入高估约三倍于全球自由贸易收益。
Most empirical policy work requires policy aggregation. Trade policy aggregation exemplifies the aggregation problem poignantly, with thousands of highly dispersed trade barriers. This article provides methods of policy aggregation that are consistent with two common objectives of empirical work. One is to preserve real income. The other is to preserve the real volume of activity in the parts of the economy being aggregated. Both objectives must be achieved for consistent multicountry policy modeling. An application to India shows that the standard atheoretic method of aggregation overstates India's real income by around three times the global gains from free trade.
