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 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 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...

Capitalizing on the latest developments in the gravity literature, we utilize two new datasets on sanctions and trade to study the impact of economic sanctions on international trade in the mining sector, which includes oil and natural gas. We demonstrate that the gravity equation is well suited...

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...

We develop a simple estimation procedure for general equilibrium (GE) comparative static analysis of gravity models. Non-linear solvers of estimated models are replaced by (constrained) regressions. Applied economists can more readily generate results, with more intuition about the working of...

We challenge the common practice of estimating gravity equations with time-interval data in order to capture dynamic-adjustment effects to trade-policy changes. Instead, we point to a series of advantages of using consecutive-year data recognizing dynamic-adjustment effects. Our analysis reveals...

Starting with Tinbergen (1962), quantifying the effects of regional trade agreements (RTAs) on international trade flows has always been among the most popular topics in the trade literature. Also not surprisingly, to estimate the effects of RTAs, most researchers and policy analysts have relied...

We try to achieve this objective in four steps. First, we focus on the original Armington CES gravity model, as a representative framework for a large class of GE models, to offer a deep analysis of the structural relationships underlying the general equilibrium gravity system, and how they can...

We capitalize on the latest developments in the empirical structural gravity literature to revisit the question of whether and how much does GATT/WTO membership affect international trade. We are the first to capture the non-discriminatory nature of GATT/WTO commitments by measuring the effects...
