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...

Duplication, delays or discrimination in CAPs can significantly increase trade costs, and this risk is reflected in the growing importance of CAPs in WTO discussions and bilateral and regional free trade agreements. This paper conducts an empirical study of the trade issues that WTO Members...

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 last 25 years have witnessed a rapid increase in regional trade agreements (RTAs). Although RTAs generally aim at lowering tariff and non-tariff trade barriers, an increasing number of trade agreements extend their scope to cover specific policy areas such as environmental protection and...

Better information on how services policies vary across economies and sectors over time would improve the empirical analysis of their impact. This paper describes the Services Trade Policy Database (STPD), a joint initiative by the World Bank and the WTO Secretariat, which builds on a database...

Despite its substantial and increasing importance to health systems and inclusive economic growth, the relationship between international trade in services and health worker mobility has been largely unexplored. However, international health worker mobility and trade in services have both been...

The geography of global value chains (GVCs) depends crucially on trade costs between countries hosting various stages of production. Some stages might be more sensitive to trade costs than others. In this paper, we exploit a value-added decomposition of bilateral trade flows to distinguish low...

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...

Trade has been recognized in the 2030 development Agenda as well as in the Addis Ababa Agenda for Action as an important means for the implementation of the Sustainable Development Goals (SDGs). This paper questions whether trade openness could be an important driver of financing for development...

Besides facilitating access to the world market, WTO accession negotiations entail a process of domestic reforms that are expected to improve the supply side of acceding economies. However, measuring the actual impact of accession remains an empirical debate. The present paper contributes to the...
