The minimum spanning tree concept from physics is used to study the process of market integration for a large group of national stock market indices. We show how the tree grows over time and describe the dynamics of its various characteristics. Over the period studied, 1997-2006, the tree shows...

This paper examines short-term and long-term comovements between developed European Union (EU) stock markets and those of three Central European (CE) countries which recently joined the EU. Dynamic cointegration and principal components methods are applied, in addition to static tests. While we...
