Gains from domestic versus international trade: Evidence from the US.

Using varieties of a rich model that considers sectoral heterogeneity and input-output linkages, this paper shows that the overall welfare gains of a region within a country can be decomposed into domestic versus international welfare gains from trade. Empirical results based on sector- and state-level data from the US suggest that about 94 percent of the overall welfare gains of a state is due to domestic trade with other states. The ocean states gain from international trade about two times the Great Lake states and about three times the landlocked states. [ABSTRACT FROM AUTHOR]
