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....

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...

As reliance on excessively short-term wholesale funding has been one of the major causes for the 2007-2009 financial crisis, recent advances in global liquidity regulation try to curb the excessive reliance on short-term wholesale funding without being clear on how such an approach will affect...

Ever since Harry Markowitz published his seminal paper on portfolio selection, investors have incorporated estimates of future volatilities and correlations into their asset allocation process. While portfolio construction methods continue to evolve, many investors continue to forecast...

We introduce extensions of the Realized Exponential GARCH model (REGARCH) that capture the evident high persistence typically observed in measures of financial market volatility in a tractable fashion. The extensions decompose conditional variance into a short-term and a long-term component. The...

The recent crisis of 2008 has revealed several challenges for the economic science, sparking a considerable amount of debate regarding the profession of economists and the role of macroeconomics and monetary policies. The first question that arose was why there was a lack of anticipation of the...

Most economists expected that the “Great Recession” produced by the financial meltdown of 2008 would usher in a resurgence of traditional Keynesian economics and a decline of what has come to be called “market fundamentalism." By contrast, also due to the inadequate size of the 2009...

This paper critically examines the quantitative approach to financial crises from two perspectives. First, the assumption of comparability of financial crises is analyzed. The key question here is: how comparable are crises? An important consideration here is the context – social and...

Government financial assets are increasingly recognized as playing an important role inassessing fiscal sustainability. However, very little research has been done on the dynamics ofgovernment financial assets compared to liabilities. In this paper, we investigate the impact ofrecent financial...
