It reduces the poverty rate by approximately one-quarter in Thailand and Viet Nam, for example. The unweighted average poverty headcount reduction for the three regions shown in annex table 6 are remarkably similar to the population-weighted averages from the Linkage model reported in annex table 5 with a similar tax-replacement assumption: the latter’s 17 per cent for Asia excluding China and India and 6.4 per cent for Latin America are just slightly above the GTAP model’s 14 per cent and 5.7 per cent, respectively. Like the global models, the case studies focused on price-distorting policies as of 2004, even though the database for their CGE models and their household survey data typically date back a little earlier in the decade.
