The formula approach used in many trade negotiations involves large formula cuts in high tariffs, with flexibilities that allow smaller cuts for selected products. Difficulties in evaluating the effects of these exceptions can create major problems. We use a politicaleconomy welfare function and...

Methodological issues arising from the estimation of tariff equivalents of barriers to services trade are very relevant for policy. These equivalents are used extensively to compute welfare gains and resource reallocations associated with partial liberalization of the sector; any measurement...
