Consistent Trade Policy Aggregation

  • James E. Anderson

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.
