We simulate a simplified version of the price process including bubbles and crashes proposed in Kreuser and Sornette (2018). The price process is defined as a geometric random walk combined with jumps modelled by separate, discrete distributions associated with positive (and negative) bubbles....

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...

Using variance decompositions in vector auto-regressions (VARs) we model a high-dimensional network of European CDS spreads to assess the transmission of credit risk to the non-financial corporate sector. Our findings suggest a sectoral clustering in the CDS network, where financial institutions...

In this article, the author presents a model of distributional properties of returns on financial instruments tied to ETFs via high-frequency statistical arbitrage. As the author's model shows, the securities subject to an ETF arbitrage exhibit a well-defined behavior, largely dependent on the...

This paper investigates the key role played by different factors, such as the use of Asset Backed Commercial Paper as collaterals in the short-term debt market, credit risk and the injection of liquidity by Central Banks through so-called unconventional measures, on the persistent spread during...

We investigate the likely sources of exchange rate dynamics in selected CIS countries (Russia, Kazakhstan, Ukraine, Kyrgyzstan, Azerbaijan, and Moldova) over the past decade (1999-2008). The analysis is based on country VAR models augmented by a regional common factor structure (FAVAR model)....

We investigate the likely sources of exchange rate dynamics in selected member countries of the Commonwealth of Independent States (CIS; Russia, Kazakhstan, Ukraine, Kyrgyzstan, Azerbaijan, and Moldova) over the past decade (1999-2010). Evidence is based on country VARs augmented by a regional...

Liechtenstein's economy has been heavily affected by the international economic downturn during the financial crisis. Additionally to the deep world recession, Liechtenstein's financial sector was challenged by the "Zumwinkel-Affair" (data of thousands of tax evaders were sold to several...

In this paper, we empirically analyze the effect of the credit crisis of 2008 by adopting coexceedance as a contagion measure. We assess the effect of news of governmental intervention and the collapse of firms during the period from 2007 to 2009 on the coexceedance. Our approach involves...
