The Inter-American Development Bank (IDB) and the Economic Commission for Latin America and the Caribbean (ECLAC) have formed a partnership to promote a regional network of computable general equilibrium (CGE) modellers that facilitates the exchange of analytical findings, techniques and data, with the ultimate objective of better serving policymakers in policy formulation. The regional meetings of CGE modellers, held annually in a different country of the region, have been instrumental in promoting interregional transfer of analytical technologies and in bringing the region closer to international best practices. This book contains a selection of studies discussed in past annual regional meetings on modelling.
