Gravity equations have been used for more than 50 years to estimate ex post the partial effects of trade costs on international trade flows, and the well-known - and traditionally presumed exogenous – “trade-cost elasticity” plays a central role in computing general equilibrium trade-flow...

Three years ago, very few economists would have imagined that one of the newest and fastest growing research areas in international trade is the use of quantitative trade models to estimate the economic welfare losses from dissolutions of major countries’ economic integration agreements...

To date, most estimates of the effects of free trade agreements (FTAs) on international trade flows have used the gravity equation in international trade, but have often yielded highly "fragile" estimates. This paper instead employs a non-parametric "matching" statistical estimation technique of...
