Abstract
There is a long history of analyzing the workability of markets regarding concentration ratios as indicators of workability. In this paper, we discuss a comparatively new concept, the Coordination Failure Diagnostics (CFD) Concept, introduced by Grossekettler (1982, 1999, 2005, 2008). The CFD-concept analyzes real market processes by means of time series analysis and investigates whether they operate efficiently or not. Furthermore, the concept can be used as a tool for detecting cartels. Therefore, we develop a System of Cartel Markers which can be used to analyze real markets. We analyze the German cement industry as an example of a cartel and find significant differences to the competitive benchmark.
