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...

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...

We propose a simple and flexible econometric approach to quantify ex-ante the "deep" impact of trade liberalization and the "hard" effects of protection with the empirical structural gravity model. Specifically, we argue that the difference between the estimates of border indicator variables for...

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 (EIAs)....

Trade facilitation policy focuses on accelerated and transparent shipment processing to reduce trade costs. A common measure to evaluate processing frictions is the time it takes to import. In this paper we translate import processing times to costs. Our theory considers that shipment processing...

This paper uses a new dataset on the universe of Canadian imports and tariffs between 1924 and 1936, disaggregated into 1697 goods originating in 112 countries, to analyse the impact on Canadian imports of interwar Canadian trade policy, including the 1932 Ottawa trade agreements. Rather than...

We quantify the economic impact of a potential secession of Catalonia from Spain. Using a novel dataset of trade flows between 17 Spanish sub-national regions and 142 countries, we estimate effects of different levels of borders on trade flows and uncover heterogeneity in country-to-country,...

We nest an extended two-way fixed effect (ETWFE) estimator for staggered difference-in-differences within the structural gravity model. To test the ETWFE, we estimate the effects of regional trade agreements (RTAs). The results suggest that RTA estimates in the current gravity literature may be...

We propose a simple method to identify the effects of unilateral and non-discriminatory trade policies on bilateral trade within a theoretically-consistent empirical gravity model. Specifically, we argue that structural gravity estimations should be performed with data that include not only...

We document key features of the deepening economic relationship between Brazil and China. This is evident from sharply increased bilateral trade and foreign direct investment flows and also from enhanced cohesion of negotiating positions in international fora. Data presented show bilateral trade...
