A nation is always related with other nations, and the trading for commodities is one of the simplest yet primary one. The way countries trade one another in the world scale can be seen as a form of network: the web of world export market. One can draw a directed arrow from a node to the other, by denoting that one node, the origin of the arc, is the exporting country and at the node at end of the arc, is the importing countries. Import can be types of merchandise or services as most of economic literatures and data publication said so .
The idea to use the network model for further insights on international trades has been an exciting and extensive research. Network model, which employs the mathematical analysis of graph, has been widely used to understand the complexity inherently persist in natural, as well as social system. The role of network analysis has been somewhat becoming a very interesting topics recently, since this method allows us to see the circumstances of observed phenomena in a whole view [cf. 3]. Network analysis has been employed to observe the interconnectedness of many things in our life where we can represent elements of the system as nodes and the connections between them as the edges. The growing works of complex network has discovered a lot of interesting patterns and statistical properties that invites major interdisciplinary researches . It has been broadly accepted that network representation of system analysis and information extraction from wide varieties of data can be useful for further insights and to reveal complexities beneath the system. There have been a lot of application of this nature of analytical works observing social system, e.g.: stock market network visualizations , network of business and innovation , political parties relations and inter-connection representation , interconnectedness among athletes based on tournament within sport tournaments , and even more.

Putting the health of our children in the hands of an exchange is insane. Most of us bought into this logic when the stock market was booming and financial engineers made tradable instruments of almost everything -- even risky mortgages. We should have learned our lesson. Yet there's still a movement for the United States to embark on a carbon-credit trading program based on a largely...
