Product Quality and Sustainability: The Effect of International Environmental Agreements on Bilateral Trade

This paper addresses the impact of sustainability in production on international trade. In particular, it examines the effect of the International Tropical Timber Agreement (ITTA) on tropical timber trade. The empirical analysis is based on a gravity equation in a difference-in-difference setting, which is estimated by a panel Heckman’s selection model. This accounts for the potentially systematic selection of trading partners into timber trade activity. We then co duct a comprehensive comparative static analysis solving the structural gravity model with and without the ITTA. This allows us to determine the trade impact of an ITTA induced increase in sustainability for participating as well as for third-countries. We find that countries participating in the ITTA exhibit a significant and substantial increase in trade intensity ranging from 4% to 6%. Furthermore, we observe that this effect is more pronounced for smaller member countries. Non-ITTA countries are confronted with reduced tropical timber flows. Version of record
