This paper explores the impact of trade on growth when firms are heterogeneous. Our findings can be viewed as relevant to the trade and growth literature on one hand and the heterogeneous-firms trade theory on the other. Our main finding – that freer trade is both anti-growth and welfare...

This paper explores the impact of trade on growth when firms are heterogeneous. We find that greater openness produces anti-and pro-growth effects. The Melitz-model selection effects raises the expected cost of introducing a new variety and this tends to slow the rate of new-variety introduction...

This Paper details the positive and normative effects of reciprocal trade liberalization when firms have endogenously determined, heterogeneous productivity levels. We show that trade liberalization leads to: (i) an anti-variety effect (the number of varieties consumed drops) in contrast to the...

A Melitz-style model of monopolistic competition with heterogeneous firms is integrated into a simple NEG model to show that the standard assumption of identical firms is neither necessary nor innocuous. We show that re-locating to the big region is most attractive for the most productivity...
