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...

We empirically test the effects of unanticipated fiscal policy shocks on the growth rate and the cyclical component of real private output and reveal different types of asymmetries in fiscal policy implementation. The data used are quarterly U.S. observations over the period 1967:1 to 2011:4. In...

We empirically test the effects of anticipated and unanticipated monetary policy shocks on the growth rate of real industrial production and explicitly test for different types of asymmetries in monetary policy implementation for two major international economies, the U.S. and Brazil. We depart...

In this paper, we investigate the forecasting ability of the yield curve in terms of the U.S. real GDP cycle. More specifically, within a Machine Learning (ML) framework, we use data from a variety of short (treasury bills) and long term interest rates (bonds) for the period from 1976:Q3 to...

A healthy and stable banking system resilient to financial crises is a prerequisite for sustainable growth. Minimization of a) the associated systemic risk and b) of the contagion effect in a banking crisis is a necessary condition to achieve this goal. The Central Bank is in charge of this...

In this paper we examine the predictability power of long term risk premium over Housing prices in U.S.A. of a period of 19 years (1991-2009). For reasons that are cited clearly in the text, the interest rate risk premium is preferred over yield curve. Under a probit framework, it is tested...
