Global frihandel i en regional värld : Hur påverkar frihandelsavtal möjligheterna att nå global frihandel?

Sammanfattning: How does the recent wave of preferential trading arrangements affect, the incentives for further trade liberalization of member states, and the possibility of obtaining global free trade? And are there any differences in this aspect between custom unions and other forms of preferential trading arrangements? These questions are well debated and have divided international trade researchers into two camps, one in favour for preferential trading arrangements and the other side against them. I have used well acknowledged researchers in the area of international trade theory to make a literature study of the above mentioned key elements in the debate. When comparing the two sides I have focused mainly on their differences, assumptions and results. I have come to the conclusion that there is nothing to be alarmed by of the wave of regionalism that’s occurring in the world today, but caution should be applied and more research in this area is necessary before any certain conclusions can be drawn. Free trade association seems to be welfare enhancing in general, with a few exceptions. I have found that the crucial points of what affect Free Trade Agreements will have on trade liberalization seems to be whether they are open or closed, how asymmetric the world is and the size of the trading blocs. The matter concerning custom unions are more alarming and seems to harm further trade liberalization in many aspects but this area also needs more research to give more reliable answers.
