The financial crisis that hit Europe in 2008 affected many spheres of the EU members' economies. It had drastic effects on the countries' economic activity, consumer spending, banking system liquidity, as well as negative impacts on interest rates and budget balances of the EU member states....

The aim of this paper is to investigate the return and volatility linkages among Moroccan stock market with that of U.S. and three European countries (France, Germany and U.K.) before and during the financial crisis. More specifically, we use stock returns in MASI, CAC, DAX, FTSE and NASDAQ as...

This paper develops a methodology for detecting and measuring contagion using high frequency data which disentangles continuous and discontinuous price movements. We demonstrate its finite sample properties using Monte-Carlo simulation, focusing on the empirically plausible parameter space....

Benoit Mandelbrot (1924-2010), a pioneering mathematician, created a new awareness of the chaos of nature - its randomness, irregular shapes, sharp edges, corners, and gaps. He developed the theory of fractals to describe these phenomena, and he also applied his concepts to financial markets....

Economic models are the tools of decision makers in governments and central banks. As such, they affect our everyday lives. But what is the actual track record of these models, and do they really work? Applying them in real time and validating them on a day-by-day basis leads to a clear...

We propose a tail dependence based network approach to study systemic risk in a network of systemically important financial institutions (SIFIs). We utilize a flexible factor copula-based method which allows us to measure the level of extreme risk in a portfolio when dependence is driven by one...

This paper presents a tractable model of non-linear dynamics of market returns using a Langevin approach.Due to non-linearity of an interaction potential, the model admits regimes of both small and large return fluctuations. Langevin dynamics are mapped onto an equivalent quantum mechanical (QM)...

Global financial conditions are poised to tighten further as the global recovery proceeds. While monetary policy normalization should be a healthy global development as growth continues to recover in advanced economies, financial spillovers seen during the taper episode-which started with the...

We employ a wavelet approach and conduct a time-frequency analysis of dynamic correlations between pairs of key traded assets (gold, oil, and stocks) covering the period from 1987 to 2012. The analysis is performed on both intra-day and daily data. We show that heterogeneity in correlations...
