I haven't done that research, but the OECD has an excellent paper that came out in the last five years on the service sector. It deals with the exponential benefit that comes from the liberalization of the service sector. They gave certain examples.
The key for the service sector is that sometimes you're able to create a hub within one jurisdiction and then branch into others.
If you went into Norway or Iceland, you might be able to take advantage of the relationship between Norway and Iceland with the EU countries or with the Euro-Mediterranean partnership. The EFTA countries are also entering into free trade agreements with Tunisia, Egypt, Jordan, and a number of the North African and Middle Eastern countries. You might be able to hop, step, and branch out from that jurisdiction. From a service perspective, it can be exponentially beneficial to enter into such a free trade agreement. You see those sorts of studies.
You also see some discussion on technical barriers to trade as well as sanitary and phytosanitary measures that could be pursued when there is agreement between two countries on standards to be adopted. These are ways of increasing trade.
Through free trade agreements, you have a better understanding of each other, a better understanding of the government processes and the standards processes that each country goes through. And with greater understanding of each other, more trade can occur because you've reduced the barriers to trade. There are some studies in those areas.
