In a three-country model of endogenous trade agreements, we study the implications of the Most Favored Nation Clause (MFN) when countries are free to form discriminatory preferential trade agreements (PTAs). While PTA members discriminate against non-member countries, MFN requires non-members to...

Quantitative results from a large class of international trade models depend critically on the elasticity of trade with respect to trade frictions. We develop a simulated method of moments estimator to estimate this elasticity from disaggregate price and trade-flow data using the Ricardian...

This paper proposes a unique overview of trade policies trends since the launch of the Doha Round, based on detailed data on tariffs and trade covering 130 countries. We show that regionalism has delivered limited effective liberalization so far, leading to only a 0.3 percentage point (p.p.) cut...

This paper shows that governments have no incentive to introduce non-tariff barriers when they are free to set tariffs but they do when tariffs are determined cooperatively. We then show three results. First, with trade liberalization, there is a progression from u sing tariffs only to quotas,...

We build on the latest developments in the structural gravity literature to quantify the partial and general equilibrium effects of GATT/WTO membership on trade and welfare. Using an extensive database covering manufacturing trade for 186 countries over the period 1980-2016, we find that the...

We demonstrate that durable MFN tariff elimination affects trade patterns through several layers, and magnitudes of effects are sizable. The WTO Information Technology Agreement's (ITA) unique setting allows us to overcome the challenges associated with identifying effects of non-discriminatory...

Regional trade agreements have proliferated in the past two decades while multilateral trade negotiations have stalled. Both these agreements are governed by the WTO and have to abide by the non-discriminatory (Most-Favored Nation, MFN) clause to varying degrees-regional agreements to a lesser...
