"This study offers new conclusions on the economic cost of a failed Doha Round. The first section is devoted to an analysis of how trade policies evolve in the long and medium runs. We show that even under normal economic conditions, policymakers modify tariffs to cope with the evolution of...

This paper aims to assess the rationales for the use of export taxes, in particular in the context of a food crisis. First, we summarize the effects of export taxes using both partial and general equilibrium theoretical models. When large countries have an objective of constant food domestic...

In 2001, the World Trade Organization launched a highly ambitious program of multilateral liberalization. Eight years later, concluding the negotiations is uncertain, though an opportunity still exists. Since 2001, many proposals on market access have been brought to the negotiating table by the...

This research has been undertaken to understand the rationale for the implementation of decreasing export taxes along the value chain in middle-income countries, in particular in the oilseeds value chain. This paper studies the implementation of Differential Export Tax (DET) rates along value...

This theoretical paper intends to provide an explanation of the implementation of behind-the-border policies, border policies, and of the inefficiency of trade negotiations. We consider a general equilibrium model of international trade with two identical countries, two commodities, a...

This paper examines the potential benefits and costs of providing duty-free, quota-free (DFQF) market access to the least developed countries and the effects of extending eligibility for DFQF access to other small and poor countries. Using the MIRAGE computable general equilibrium model, the...

Traditional weighted-average measures of trade distortions are widely used in analyzing global and regional reforms, despite well-known deficiencies. This paper develops and applies optimal aggregators for the real-world case of multiple countries and commodities with much more detailed...

In this paper, we provide an overview of the agricultural trade negotiations within the current World Trade Organization (WTO) negotiations and we show that including agriculture in the Doha Development Agenda talks is important both economically and politically, although the political...

"We herein use a world Computable General Equilibrium (CGE) model to simulate 143 potential trade reforms and seek solutions to the issues hampering progress in the Doha Development Agenda (DDA). Inside the domain defined by all these possible outcomes, we apply the axiomatic theory of...
