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...

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.

The article presents the notion of detection of overt or tacit collusion equilibrium in the context of choice of the appropriate econometric method, which is determined by the amount of information that the observer possesses. There has been shown one of the collusion markers coherent with an...

The paper develops a simple supergame model of collusion that focuses on the role of fixed (exogenous to game played) system of quantity market shares. Conclusions implied by the model could be used to motivate data - saving markers of collusion based on market price behavior. Following...

In the paper time-frequency analysis in the form of the maximal overlap discrete wavelet transform (MODWT) and its complex variant – the maximal overlap discrete Hilbert wavelet transform (MODHWT) is applied to study changing patterns of business cycle synchronization between Poland and 8 euro...

In the paper the process of equity market integration in Europe is examined from the wavelet perspective. The method applied is the Continuous Discrete Wavelet Transform that enables to perform global and local wavelet variance and correlation decompositions. In particular, questions about...
