Horizontal mergers have a large impact by inducing a long-lasting change in market structure. Only in an industry with substantial entry barriers is a merger not immediately counteracted by post-merger entry. To evaluate the duration of the effects of a merger, I use the model of Abbring and...

Cartel detection is usually viewed as a key task of either competition authorities or compliance officials in firms with an elevated risk of cartelization. We argue that customers of hard core cartels can have both incentives and possibilities to detect such agreements on their own initiative...

Although the pricing dynamics of hardcore cartels have been studied intensively from a theoretical perspective, empirical evidence is still rare. We combine publicly available data with a unique private data set of about 340,000 market transactions from 36 smaller and larger customers of German...

The European Court of Justice's definition of when a firm has a dominant position has recently come under attack as being meaningless and impossible to measure. We argue that both attacks are wrong, suggest an economic interpretation of domination and propose how it may be measured using modern...

Public and private action against cartels is an internationally recognized cornerstone of antitrust enforcement.

Coordination Failure Diagnostics (CFD) is a model that analyses real market processes with the help of time pattern analysis and investigates whether they operate efficiently (See www.wiwi.uni-muenster.de/cfd). The CFD cartel-audit should enable the detection of cartels via characteristic market...

Kartellerin tespitine yönelik olarak başlatılan ancak kesin bir sonuca ulaşamayan çabalar aksine kartelin güçlenmesine yolaçabilir. Varlığı kesin olarak saptanan karteller yasanın elverdiği en ağır şekilde cezalandırılmalıdır. Kartel uygulamalarında görülebilecek yetersiz...

A kiskereskedelmi árrögzítés évtizedek óta vitatott kérdés a közgazdasági elméletben. Az Egyesült Államok legfelsőbb bíróságának közelmúltbeli döntése - megszüntetve az ilyen típusú árkorlátozások önmagában törvénytelennek ítélését - ismételten felhívta a...
