In this study, we examine the issue of business cycle synchronization from a historical perspective in 27 developed and developing countries. Based on a novel complex network approach, the Threshold-Minimum Dominating Set (T-MDS), our results reveal heterogeneous patterns of international...

Graph theory is an essential tool for the modeling of complex networks. It can be used for network control and monitoring. The latter is usually performed using a representative subset of the whole network identified with the Minimum Spanning Tree (MST) methodology. The MST, however, bears...

This paper examines the co-movement patterns of European business cycles during the period 1986-2011, having as a focal point the year of the euro coin introduction, in 1999. We work within a Graph Theory context and apply a rolling window to study the evolution of the network that corresponds...

This study performs a long-run, inter-temporal analysis of income inequality in the U.S. for the period 1916-2012. We use a) descriptive analysis to examine the evolution of inequality through time and b) complex network tools, more specifically an optimization technique called the...

In this paper we model the United Kingdom's Consumer Price Index as a complex network and we apply clustering and optimization techniques to study the network evolution through time. By doing this, we provide a dynamic, multi-level analysis of the mechanism that drives inflation in the U.K. We...

We test the validity of Purchasing Power Parity theory, examining the Real Exchange Rate of 23 OECD countries for mean-reversion. In doing so, we estimate the Hurst exponent which is a well-established estimator of long memory in time series analysis. The innovation of our approach is that we...

This survey provides an up-to-date summary of the literature that relates to the study of business cycle synchronization. Various paths have been followed through time in empirically testing business cycle co-movement and different data sets have been explored so that to date consensus still...

In this study, we examine the issue of business cycle synchronization from a historical perspective in 27 developed and developing countries. Based on a novel complex network approach, the Threshold-Minimum Dominating Set (T-MDS), our results reveal heterogeneous patterns of international...

Graph Theory and network analysis have received great attention lately in the process of analyzing complex economic systems. Here we propose the use of the Minimum Dominating Set concept in order to identify a representing set of nodes which can describe the collective behavior of an entire...
