For more than forty years, the gravity equation has been a workhorse for cross-country empirical analyses of international trade flows and, in particular, the effects of free trade agreements (FTAs) on trade flows. However, the gravity equation is subject to the same econometric critique as...

We address three themes on the New Regionalism. First, the prominent analogy to a “spaghetti bowl” of economic integration agreements (EIAs) should be replaced by reference to a « market » for EIAs. We suggest a systematic economic framework for analyzing « competitive...

Bilateral investment treaties (BITs) have proliferated over the past 50 years such that the number of pairs of countries with BITs is roughly as large as the number of country-pairs that belong to bilateral or regional preferential trade agreements (PTAs). The purpose of this study is to provide...

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...

Recent quantitative trade models treat import tariffs as pure cost shifters so that their effects are similar to iceberg trade costs. We introduce revenue-generating import tariffs, which act as demand shifters, into the framework of Arkolakis, Costinot and Rodriguez-Clare (2012), and generalize...

For the estimation of structural gravity models using PPML with countrypair, exportertime and importer-time effects it proves useful to exploit the equilibrium restrictions imposed by the system of multilateral resistances. This yields an iterative projection based PPML estimator that is...
