Abstract: This paper addresses three questions relating to the very extensive use of the GTAP global trade protection database: Are there additional price-distorting policy instruments worthy of inclusion in the base year? What is the appropriate counterfactual set of price distortions in the year of concern (such as when a proposed reform is expected to be fully implemented, as distinct from the base year)? And how are the price distortions (e.g. tariff rates) on individual products aggregated to the GTAP product groups? We show the estimated welfare effects of policies can change substantially when more-appropriate measures of distortions are used.
