Heterogeneous Effects of Preferential Trade Agreements: How does Partner Similarity Matter?

Abstract

This paper examines how dissimilarity of partner country characteristics affects the change in trade flows under a preferential trade agreement (PTA). Our results show that the more similar the partner countries are, the larger the increase in intra-bloc trade is under a PTA. Particularly, there is a substantial “development neighborhood premium”: the gain for developing countries from a PTA among themselves is about two and a half times that from partnering with industrial countries. Our findings challenge the perception that by becoming more integrated with industrial countries, developing countries could automatically gain access to a much larger and lucrative export market.
