"Estimating effects of price-distorting policies using alternative distortions databases"
by Anderson, Kym


Abstract
The 2004 GTAP protection database is predominantly based on aggregated tariffs on imports in a past year. This paper raises two concerns: What about the other price-distorting policy instruments in the agricultural and food sectors? And how can the distortion estimates be adjusted to ensure the appropriate counterfactual in the year of concern (such as the current year, or a future year if a proposed reform would not be fully implemented for some time)? This paper assesses the significance of these concerns by using the World Bank’s global economy-wide Linkage Model. It does so by first estimating the effects of goods trade-related policies as of 2004 using the standard Version 7 GTAP protection database. These are then compared with the effects using alternative protection databases. Since agricultural distortions have been estimated over recent years to contribute more than two-thirds of the global welfare cost of policy distortions to goods markets and to have severely limited trade in farm products, special attention is given to the effects on that sector.
