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...

This paper studies capital market integration in Middle Eastern and North African (MENA) countries and its implications for international portfolio investment allocation. Starting with four cointegration methodologies, we significantly reject the hypothesis of a stable, long-run bivariate...

This study re-examines the results of Ciner (2001), who claims that the historically stable relationship between gold and silver has broken down in the 1990s. It is shown, using a longer run of data, for both cash and futures, that this finding may be unwarranted. In particular a recursive...

This paper investigates the relationship between seven mood-proxy variables and a global equity dataset using a variety of group tests. The mood-proxy variables are constructed from weather data (precipitation, temperature, wind, geomagnetic storms) and biorhythm data (seasonal affective...

This paper examines the relationships between Russian and other equity markets over the period of 1995-2004. To account for potential instability in the market relationships we apply a number of cointegration approaches: Gregory-Hansen [1996. Residual-based tests for cointegration in models with...
