How large are the estimated gains from trade from a reduction in trade costs in the heterogeneous firms Melitz (M) model compared with the Armington (A) and Krugman (K) models? Surprisingly little is known beyond the one-sector model. This paper analyzes this question using a global trade model...

To analyze the Deep and Comprehensive Free Trade Area (DCFTA) between Ukraine and the EU we develop a multi-region general-equilibrium simulation model calibrated to GTAP 8.1 data. We implement three alternative trade structures for services and manufactured goods: a.) a standard specification...

We analyze subglobal action to mitigate climate change with a consideration of recent advances in the theory of international trade. Subglobal action impacts emissions in unconstrained countries (carbon leakage) through international trade channels. Consequently, estimates of the efficacy of...

This chapter considers alternatives to the Armington formulation of international trade found in most computable general equilibrium (CGE) models. International trade structures consistent with the monopolistic competition models suggested by Krugman (1980) and Melitz (2003) are presented in a...

How large are the estimated welfare gains from changes in trade costs in a Melitz based trade model compared with models based on Armington and Krugman? We examine model features and scenarios that are important for policy that are unexamined in the literature. Starting with the stylized model...
