“The Architecture of Globalization: A Network Approach to International Economic Integration” by Javier Reyes and Raja Kali:
We combine data on international trade linkages with network methods to examine the global trading system as an interdependent complex network. We map the topology of the international trade network and suggest new network based measures of international economic integration, at both a global system-wide level and a local country-level. We develop network based measures that incorporate not only the volume of trade but also the influence that a country has on the international trading system. These measures incorporate the structure and function of the network and may provide a more meaningful approach to globalization than current measures based on trade volumes. We find that in terms of participation and influence in the network, global trade is hierarchical with a core-periphery structure at meaningful levels of trade, though integration of smaller countries into the network increased considerably over the 1990’s. The network is strongly “balkanized” according to geography of trading partners but not as strongly by income or legal origin. Using these new measures we find that a country’s position in the network has substantial implications for economic growth and that network position is a substitute for physical capital but a complement to human capital. We therefore suggest that a network approach to international economic integration has potential for useful applications in international business, finance and development.
Last week, I saw Dr. Kali present an application of their measures: “Financial Contagion on the International Trade Network”
The data are from the Feenstra et al. NBER set of bilateral trade data by commodity for 1962-2000, which sounds powerful based on Kali’s description.
