In the paper time-scale (wavelet) analysis is suggested as a tool for examining business cycle synchronization. Wavelet analysis enables to examine stochastic processes simultaneously in the time and frequency domains. Due to this the approach makes it possible to investigate time varying...

In the paper the Haar wavelet transfer function models are suggested as a way to parsimoniously parametrise the impulse responses and construct models with parameters providing an insight into the frequency content of the relationships under scrutiny. Besides, the models enable to verify...

In this paper we verify usefulness of a variance marker of collusion in an application to Lysine prices during well known cartel/competition episode. As an econometric method of detection of structural change in price volatility during collusive and competitive phase wavelet analysis was...

In the present paper an attempt was made to verify the possibilities of the use of a marker of structural changes of market price variance in the detection of trade collusion between business players. We used the theoretical model of strategic behaviour of trade players with the assumption of...
