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 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...

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...

The objective of this manuscript is to serve as a practical guide for evaluation of the general equilibrium (GE) effects of trade policy using the structural gravity model. We try to achieve this objective in four steps. First, we focus on the original Armington-CES gravity model, as a...

Despite the strong pace of globalization, the distance effect on trade is persistent or even growing over time (Disdier and Head, 2008). To solve this distance puzzle, we use the recently developed gravity equation estimator from Helpman, Melitz and Rubinstein (2008), HMR henceforth. Using three...
