The main reason for the importance of international cooperation is simple: the state is a human abstraction.
If you contaminate the world in your own country, there is no way to avoid having a common resource called Earth. Another advantage to support this view is that the Earth's water circulation allows each creature to drink the same water from a huge circular public pool.
Since then, international coordination on the use of resources is mandatory, international cooperation can take over and undertake it.
Furthermore, since international trade is also based on international cooperation, unless there is agreement among different groups, we will offer a number of basic services such as currency exchange between currencies, credit card, bank transfer, international purchase or sale I can not do it.
Finally, international cooperation in developing countries may be important, but sometimes it is not so. The situation is that it is not cooperation but the use of resources from developing countries.
If the country closes its borders and avoids international interaction and cooperation (even imagining things like Cuba) of course, you can survive and prosper. International cooperation is important, but it is not mandatory except in rare cases such as nuclear weapons and excessive pollution. The life that exists is a resource based on the world
Of course, "formal" alone is not enough, the province has manipulated the numbers. Here is why international cooperation is very important, so the National Bureau of Statistics of different countries not only cooperate with one another, but also stress each other to demand transparent, comparable and reliable data I will. Based on the fundamental principles of UN official statistics adopted in 1994 and reaffirmed in 2014, the 2015 OECD Recommendation highlights the need for trust data and provides appropriate interpretation and transparency.
We emphasize the contribution of theoretical methods to international collaborative research, but this comment goes beyond the success of the formal model. First, the progress of international cooperation research is intertwined with the substantial knowledge of international politics. Indeed, large and growing research on international cooperation is not directly dependent on formal methods, but it is believed to be deeply influenced by it. Second, the theory of international cooperation is a stepwise research program that faces the limit of its analysis and responds to it. One of the main advantages of formal work is to help researchers clarify their assumptions and overcome their efforts by helping researchers decide their limits.
