Trade agreements as public goods

Aaditya Mattoo's picture

If a trade economist were abruptly woken up by somebody shouting, “preferential trade agreements” (PTAs), their first thought is likely to be “trade creation among participants and trade diversion away from those left out.” That is a measure of the influence of Jacob Viner’s classic book The Customs Union Issue on the profession, on the policy debate and on our attitude towards PTAs.
 
Brexit and the renegotiation of NAFTA have renewed interest in the impact of trade agreements and the consequences of undoing them.  In a recent paper, Mattoo, Mulabdic and Ruta (2017) and column (VOXEU), we use new information on the content of PTAs to examine their trade effects.
