Economic theory suggests that countries' tariff commitments in trade agreements reflect their import market power at the time of negotiations. However, as countries grow, their market power in different sectors can change in unforeseen ways and their commitments may no longer reflect changed...

When looking at the conditions of trade in natural resources the world appears upside down: tariff protection in natural resources sectors is generally lower than for overall merchandise trade, while export restrictions are twice as likely as in other sectors. On the other hand, tariff...

In recent years, quantitative analysis of the effects of policies on economic outcomes has grown sharply. These exercises in quantification have been made possible by advances in theory and analytical techniques, and no less importantly, by the dramatically increased computational and data...

Then, we integrate the latest developments in the empirical gravity literature and we offer six recommendations to obtain reliable partial equilibrium estimates of the effects of bilateral and non-discriminatory trade policies within the same comprehensive, and theoretically-consistent...

The objective of this manuscript is to serve as a practical guide for estimations with the structural gravity model. After a brief review of the theoretical foundations, we summarize the main challenges with gravity estimations and we review the solutions to address those challenges. Then, we...

This paper studies the effects of trade policy uncertainty on the extensive and the intensive margins of trade for a sample of 149 exporters at the HS6 digit level. We measure trade policy uncertainty as the gap between binding tariff commitments under trade agreements (multilateral and regional...
