We estimate the effect of RTAs on bilateral exports by means of a gravity model analyzing its sensitivity to different specifications and methods. RTAs generate a sizable positive effect. However, shifting to country-pair and time-varying fixed effects systematically reduces coefficients....

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 and...

Despite widespread anecdotal evidence that lower trade barriers increase international trade, there is little firm quantitative evidence of the ‘trade-cost elasticity’ of trade flows, one of the two key aggregate statistics that have recently been identified as sufficient to quantify the...

East Asian liberal intergovernmental integration is unlikely to occur without formal engagement by the United States. An Asian Union is therefore improbable. The European Union model is not transferrable to East Asia in that the former is a multilateral organization that has emerged that can...
