We consider the interaction between an incumbent firm and a potential entrant, and examine how this interaction is affected by demand fluctuations. Our model gives rise to procyclical entry, prices, and price-cost margins, although the average price in the market can be countercyclical if the...

We provide a comprehensive quantitative assessment of cartels and the related cartel enforcement process in the European Union (EU) from 2001 to 2015. In a first step, we present a detailed characterization of all cartel cases decided by the European Commission (EC) with respect to various...

This study constructs a simplest model to examine anticompetitive exclusive contracts that prevent a downstream buyer from buying input from a new up-stream supplier. Incorporating Nash bargaining into the standard one-buyer-one-supplier framework in the Chicago School critique, we show a...

We provide an example for an errors in variables problem which might be often neglected but which is quite common in lab experimental practice: In one task, attitude towards risk is measured, in another task participants behave in a way that can possibly be explained by their risk attitude. How...

We use a dataset of 615 firms which participated in 114 illegal cartels - convicted by the European Commission between 1999 and 2016 - to investigate the determinants of the duration of a firm's participation in a cartel. Applying a Weibull proportional hazard model with a particular focus on...

The begin and end dates of cartels are often ambiguous, despite competition authorities stating them with precision. The legally established infringement period(s), based on documentary evidence, need not coincide with the period(s) of actual cartel effects. In this paper, we show that misdating...

We study a problem of optimal auction design in the realistic case in which the players can collude both on the way they play in the auction and on their participation decisions. Despite the fact that the principal's opportunities for extracting payments from the agents in such a situation are...

About the end of 2006, Microsoft began delivering its new Windows Vista PC operating system to large commercial customers, followed by final users and small businesses. Even before the product reached the market, the dominant provider of PC operating systems worldwide was accused over and over...

Der Lohnfindungsprozess in Deutschland ist einem starken Wandel unterworfen, denn das Flächentarifsystem befindet sich auf dem Rückzug. Stattdessen gewinnen Individualarbeitsverträge sowie konkurrierende und berufsständische Kollektivverträge an Bedeutung. Politik und Rechtsprechung...
