In this paper, we map the process of synchronization of the Visegrad Four within the framework of the European Union using wavelet techniques. We show that the relationship of among countries is dynamic and that it varies over time and across frequencies. We study the synchronization applying...

In this paper, we map the process of synchronization of the Visegrad Four within the framework of the European Union using the wavelet techniques. In addition, we show that the relationship of output and key macroeconomic indicators is dynamic and varies over time and across frequencies. We...

In our study, we consider a new approach to quantify the effects of economic shocks on monetary transmission. We analyse the widely known phenomenon of price puzzle in a time-varying environment using the frequency decomposition. We use the frequency response function to measure the power of...

In this paper, we map the process of business In this paper, we map the growth cycle synchronization across the European Union, specifically focusing on the position of the Visegrad Four countries. We study the synchronization using frequency and time-frequency domain. To accommodate for dynamic...

We propose a general framework for measuring frequency dynamics of connectedness in economic variables based on spectral representation of variance decompositions. We argue that the frequency dynamics is insightful when studying the connectedness of variables as shocks with heterogeneous...

We study the relationship between conditional quantiles of returns and the long-, medium- and short-term volatility in a portfolio of financial assets. We argue that the combination of quantile panel regression and wavelet decomposition of the volatility time series provides us with new insights...
