The study examines whether the long-run validity of PPP holds in some major advanced and developing economies. The study employed the smooth time-varying cointegration (TVC) and time-varying detrended fluctuation analysis (DFA) methodology, and we are not aware of any study that has applied TVC...

This paper develops and applies a novel estimation procedure for quantile regressions with time-varying coefficients based on a fully parametric, multifactor specification. The algorithm recursively filters the multifactor dynamic coefficients with a Kalman filter and parameters are estimated by...

European wholesale power prices have decreased substantially in recent years, bringing several large utilities to the brink of severe financial problems. In this study, we identify and determine the impact of several fundamental drivers on the electricity wholesale day-ahead price using long...

This study investigates the long-run relationships and short-run dynamic causal linkages between the stock exchange of Egypt and its counterparts in the Group of Seven (G7) countries, prior to and following the tragic events of September 2001, utilizing Johansen's cointegration and variance...

Financial market volatility is an important element when setting up port- folio management strategies, option pricing and market regulation. The Subprime crisis affected all markets around the world. Daily data of twelve stock indexes for the period of October 1999 to June 2011 are studied using...

Our research project analyses the suitability of social responsible investments (SRI) and alternative asset classes (in particular commodities, hedge fund in-vestments, high-yield bonds) for the portfolio management of German Pension Insurance Funds (Pensionskassen), the largest external...

The classic 'logistic' model has provided a realistic model of the behaviour of Covid-19 in China and many East Asian countries. Once these countries passed the peak, the daily case count fell back, mirroring its initial climb in a symmetric way, just as the classic model predicts. However, in...

In the paper we test for the different reactions of stock markets to the current financial crisis. We focus on Central European stock markets, namely the Czech, Polish and Hungarian ones, and compare them to the German and U.S. benchmark stock markets. Using wavelet analysis, we decompose a time...

In this paper, we contribute to the literature on international stock market comovement. The novelty of our approach lies in usage of wavelet tools to high-frequency financial market data, which allows us to understand the relationship between stock market returns in a different way. Major part...

In this paper we will be estimating risk-neutral densities (RND) for the largest euro area stock market (the index of which is the German DAX), reporting their statistical properties, and evaluating their forecasting performance. We have applied an innovative test procedure to a new, rich, and...
