Is trade pessimism justified? Opening the "black box" of trade modeling

This report examines the discrepancies in economic simulations regarding the welfare gains of multilateral trade liberalization, specifically focusing on the shift from optimistic early projections of the Doha Round to more recent, smaller estimates for the global economy and developing countries.

• Early simulations of the World Trade Organization's Doha Round suggested that complete liberalization of merchandise trade could increase the world economy's wealth by $800 billion, with developing countries capturing approximately two-thirds of those gains.
• More recent simulations of full multilateral trade liberalization have produced significantly lower welfare gain values than previous estimates, with the projected benefits for developing countries now appearing to be very small.
• Trade economists primarily use computerized general equilibrium (CGE) models to predict changes in economic variables resulting from trade liberalization, though these models face criticism for their limitations and produce diverging results among different modelers.
