Traditional CGE models with Armington assumption fail to capture the extensive margin of trade, thereby underestimate the trade and welfare effects of trade opening. To address this problem, this paper introduces the Melitz (2003) theoretical framework with firm heterogeneity and fixed exporting...

This paper develops a methodology for trade policy analysis of costs and benefits of alternative regional integration scenarios. The methodology is based on the disaggregated gravity equation, which is applied to calculate the impact of the EU enlargement on integration strategies of non-member...

The economic implications and the income distribution effects of the customs union (CU) between Turkey and the European Union (EU) have been studied by applying a general equilibrium model to the Turkish economy under alter - native hypotheses for the labour market. The numerical results show...

In this paper we use a gravity model in order to estimate the magnitude of potential trade flows between Greece and nine Balkan countries. We adopt a two stage approach. At the first stage the coefficients of the gravity model for the implemented trade between Greece and thirty trade partners...

If South Asia and Sub-Saharan Africa are to become constructively engaged in the next attempt by World Trade Organization (WTO) members to liberalize trade multilaterally, they need to be convinced that there will be sufficient gains from trade reform to warrant the inevitable costs of...

The purpose of this paper is to estimate the impact of the integration of Maghreb countries into a free trade area on the main macroeconomic aggregates. By using the MIRAGE model and MacMap database, we tested different scenarios to estimate the gains or the potential losses of various plans of...

This paper provides a quantitative assessment of the tariff changes implemented by the Philippines in 2005. It evaluates the impacts of these changes on the macroeconomy and on major industries and regions of the country. It also examines the impact of alternative tariff policies that the...

This paper shows a new exposition of the Trade Diversion Effect when Free Trade Agreements are created. Hub and spoke type of trade networks cause systemic overproduction, and member countries exit from the markets, whereas perfectly connected networks create sustainable markets in any number of...

The agreement recently signed between Morocco and the United States foresees several modalities in dismantling tariffs. Our simulations show that the various modalities of trade liberalization may have different impacts on the welfare, the rate of growth and the sectoral trade balance of these...

When impacts of WTO market access proposals are analyzed with economic trade models, it is necessary to aggregate tariff data from the detailed tariff line level to the model level. In this article import tariffs and implemented import tariff cuts are aggregated from the HS6-digit tariff line...
