Revisiting the ‘Cobden-Chevalier network’ trade and welfare effects

This study revisits the trade and welfare effects of 19th century bilateralism exploiting the latest developments in structural gravity models, including the consideration of domestic trade. Using bilateral trade data between 1855 and 1875, I show that the Cobden-Chevalier network, i.e. a system of bilateral trade agreements including the Most Favored Nation clause, has large, positive and significant effects on members’ trade. These, however, are heterogeneous at the treaty-level. I then calculate its general equilibrium effects on total trade and welfare. They are considerable, while trade diversion effects are negligible. These results reshape the understanding of the Cobden-Chevalier network, helping in further rationalizing the “free trade epidemic” of the 1860s and 1870s.
