"Incorporating heterogeneous export supply and import demand elasticities in a CGE model"
by Aguiar, Angel, Maksym Chepeliev, Alla Golub, Thomas Hertel, Anson Soderbery and Dominique van der Mensbrugghe

The objectives of this work are to apply, in the context of a computable general equilibrium (CGE) model, advances in export supply and import demand elasticities estimation and examine the implications of heterogeneity for a CGE model mechanisms and outcomes. The analysis is based on the extension of the GTAP model, called GTAP-HS. The GTAP-HS model allows for the incorporation of detailed trade data and analysis of trade policies at the level of the Harmonized System’s (HS) “tariff line”. Importer-exporter-good specific export supply and import-good specific import demand elasticities are estimated using Soderbery (2018) method. The GTAP-HS model is then modified to incorporate the heterogeneous export supply and calibrated to the estimated trade elasticities. The model is applied to evaluate the impacts of retaliatory tariffs imposed on U.S. vegetables, fruits, and nuts sectors and explore how uncertainties in the trade elasticities contribute to uncertainty in policy outcomes.
