This paper uses computational techniques to assess whether or not various propositions that have been advanced as plausible in the literature on regional trade agreements may actually hold. The idea is to make probabilistic statements as to whether propositions of interest might hold, rather...

The GATT/WTO Article XXIV prevents a customs union (CU) from raising its common external tariff. In this paper, we compare CU formation with and without this Article XXIV constraint. We show, in a multi-country oligopoly model, that for a given CU structure, Article XXIV improves world welfare...

This paper examines the impact of the European Union-South Africa Trade Development and Cooperation Agreement (EU-SA TDCA) on trade between the RSA and Botswana, Lesotho, Namibia and Swaziland (BLNS). The results indicate that demand for imports are income elastic and price inelastic. This...

This paper is the final report of a research project whose aim was to analyse the methodology of calculating the costs and benefits for the Czech Republic, Hungary, Poland and Slovenia of the envisaged accession to the European Union. The research focused particularly on the impact of the...

The Common Market for Eastern and Southern Africa (COMESA) is a Free Trade Area (FTA) regional trade agreement in Africa. Currently, Ethiopia is negotiating to join COMESA FTA. This study assesses the impact of three regional trade arrangements, COMESA FTA, customs unions, and the European...

This study offers an empirical microlevel analysis of the pass-through effects of the East African Community Common External Tariff on consumer prices in Kenya. Using data from the Kenya Integrated Household Budget Surveys conducted in 2005 and 2015, this research employs a fixed-effects model...

This paper shows that the WTO's Article XXIV increases the likelihood of free trade, but may worsen world welfare when free trade is not reached and customs unions (CUs) form. We consider a model of many countries. Article XXIV prevents a CU from raising its common external tariff, which makes...

This paper analyses the customs union problem in a model containing a continuum of products. The continuum is in three dimensions, so that three countries each have a distinct comparative advantage. Trade patterns are endogenously determined, and changed by policy. This is in the tradition of...

Increased market access from Free Trade Agreements (FTAs) promised by policy makers is often diluted by preferential rules of origin (ROO). This paper discusses two policy options one direct, and one indirect -- with regard to limiting the impact of NAFTA ROO on trade, and illustrates the impact...

The case is studied where two small countries wanting to set second-best tariffs to maximize objective functions move from the situation where they can set their most appropriate tariffs to the situation where they form a customs union. By dividing the overall effect of forming customs unions...
