Stock Market Synchronicity And The Global Trade Network: A Random-Walk Approach

Free registration required

Executive Summary

Do countries which are more centrally located in the global trade network have more synchronized stock markets? The people use global trade data to construct a novel measure of network position, Random Walk Between's Centrality (RWBC), that is especially well suited to this question. RWBC measures the extent to which a country lies on random pathways in-between countries and is therefore more likely to be a conduit in the random transmission of a shock across global markets. They use a panel dataset for 58 countries spanning the period 1990-2000 to find that a country's position in the world trade network as described by RWBC is associated with greater stock market synchronicity.
