Abstract: | We summarize the evidence on the gains from trade in monopolistic competition models, arising from three sources: (i) price
reductions due to increasing returns to scale; (ii) increased product variety available to consumers; (iii) self-selection
of firms with only the most efficient firms surviving after trade liberalization. There is little direct evidence to support
the first source of gains from trade, though some indirect evidence from the European Union. The second and third sources
of gains from trade find strong empirical support from studies from various countries, relying on new models and new empirical
methods.
