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...

This paper presents a review of a methodology of detection of overt or tacit collusion in the light of the modern competition policy based on the game theory. In this paper a consistent research procedure for identification and detection of collusion is proposed.

This article is devoted to the problem of the detection of overt or tacit collusion equilibrium in the context of the choice of the appropriate econometric method, a choice that is determined by the amount of information that the observer possesses. The author addresses this problem in two...

In this paper a supergame model of collusion based on fixed cartel quota exogenously provided by cartel members’ agreement is developed. The model provides theoretical motivation of price wars and variance screen of collusion. We use the model to explain behavior of well known Lysine...

The paper is devoted to a case of a cartel in Polish cement industry. Short description of the industry and characteristics of the cartel with its fundamental illegal practices, market sharing and price fixing have been done. We focused on examination of possibility of detection of a cartel like...

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 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...
