This paper examines the dynamics of stock prices in Ukraine by estimating the degree of persistence of the PFTS stock market index. Using long memory techniques we show that the log prices series is I(d) with d slightly above 1, implying that returns are characterised by a small degree of long memory and thus are predictable using historical data. Moreover, their volatility, measured as the absolute ...

We investigate whether the willingness to take investment risk is a sex-linked trait and link the results to the country's gender equality regime. Our empirical analysis involves household data on financial asset holdings as well as on self-reported risk tolerance for Austria, Italy, the Netherlands and Spain. Of those countries, Italy is by far the country with the greatest degree of gender inequality ...

The GARCH(1,1) model and its extensions have become a standard econometric tool for modeling volatility dynamics of financial returns and port-folio risk. In this paper, we propose an adjustment of GARCH implied conditional value-at-risk and expected shortfall forecasts that exploits the predictive content of uncorrelated, yet dependent model innovations. The adjustment is motivated by non-Gaussian ...

This study examines the nature of the linkages between stock market prices and exchange rates in six advanced economies, namely the US, the UK, Canada, Japan, the euro area, and Switzerland, using data on the banking crisis between 2007 and 2010. Bivariate GARCH-BEKK models are estimated producing evidence of unidirectional spillovers from stock returns to exchange rate changes in the US and the UK, ...

This paper examines the PPP hypothesis analysing the behaviour of the real exchange rates vis-à-vis the US dollar for four major currencies (namely, the Canadian dollar, the euro, the Japanese yen and the British pound). An innovative approach based on fractional integration in a multivariate context is applied to annual data from 1970 to 2011. Long memory is found to characterise the Canadian dollar, ...

Die Insolvenz einer großen und stark vernetzten Bank führt zu Verlusten bei anderen Banken und kann das Finanzsystem destabilisieren. Eine stärkere Systemperspektive der Finanzmarktregulierung ist deshalb essentiell. Dieser Artikel analysiert, wie das Problem der Systemrelevanz im bisherigen Regulierungsrahmen berücksichtigt wird. Die Analyse kommt zu dem Schluss, dass der von Basel III vorgesehene ...
