NAFTA: Past, Present and Future

The North American Free Trade Agreement (NAFTA) – an extension of the Free Trade Agreement (FTA) between Canada and USA to include Mexico – went into effect on January 1, 1994, primarily as an agreement to eliminate restrictions on trade and investment over the course of twelve years. NAFTA is a trade agreement and after twelve years remains as such with limited prospects, if any, of widening or deepening the integration process. Despite its narrow scope, the agreement became, from the start, controversial – and continues to be so – not only for trade and investment matters but for a whole host of other related issues. The other related issues include: the dispute settlement mechanism and side agreements on labor and environmental issues

The future of the US Dollar and its competition with the Euro

Since the collapse of the Bretton Woods Global International System in 1971, the world economy has experienced significant currency volatility. The major economies of the world have addressed such volatility differently. The EU has chosen to follow a monetary union and introduced successfully a new currency. The U.S. has paid less attention to the fluctuations of the dollar and has pursued an independent monetary policy to promote national economic stability. Japan has seen its currency appreciate significantly. This paper argues that while trade and growth across the globe are doing well, financial developments are intensifying the competition between the U.S. dollar and the euro. Three possible future scenarios are developed and discussed.peer-reviewe

Asymmetrical economic and institutional changes in the Western Balkans : cooperation with the European Union

The Western Balkans have historically been a poor area of Europe. The total population of the Western Balkans is 24.7 million. Ethnic differences of long standing have led to conflicts and to political and economic instability. Poverty and instability have combined to produce a vicious circle of institutional backwardness. Recent conflicts in Croatia, Bosnia-Herzegovina and Kosovo have aggravated an already adverse economic situation. GDP in 1999 was substantially lower than that in 1989. The EU plans to enter into contractual relationships with all the Western Balkans in the form of Stabilization and Association Agreements (SAAs). The pacts are aimed at helping to establish economic and political stability, to implement institutional reforms, to practice regional free trade and cooperation and to privatize the economies of Western Balkans. These are also the presumed goals of the Western Balkans. This study focuses on a review of the progress made by the Western Balkans toward meeting the above stated challenges. A main conclusion is that the attainment of these goals has been asymmetrical for economic, political and institutional reasons.peer-reviewe

Primary Carcinoma of the Gallbladder

Carcinoma of the gallbladder is a relatively rare malignancy which is difficult to diagnose. The advent of improved imaging methods and the expansion of interventional radiology however, combined with advances in surgical technique, has produced a change in attitude towards this tumour. The available world literature since 1960 has been reviewed and is presented in this article. However, whilst the outlook for diagnosis and treatment is improving, clearly the association with cholelithiasis (between 45% and 100%), is a cause for concern particularly with the advent of treatments (lithotripsy, percutaneous gallstone extraction) which leave gall bladder mucosa and residual fragments of stone in situ

Resource constrained routing and scheduling: Review and research prospects

In the service industry, it is crucial to efficiently allocate scarce resources to perform tasks and meet particular service requirements. What considerably complicates matters is when these resources, for example skilled technicians, nurses, and home carers have to visit different customer locations. This paper provides a comprehensive survey on resource constrained routing and scheduling that unveils the problem characteristics with respect to resource qualifications, service requirements and problem objectives. It also identifies the most effective exact and heuristic algorithms for this class of problems. The paper closes with several research prospects
