The paper analyzes gross upward pricing pressure indices called iGUPPI to assess the effects of a merger between vertically integrated firms where in the downstream market also independent rivals are active. Such indices could be used e.g. to screen mergers between mobile network operators which...

One central issue tackled in epistemic game theory is whether for a general class of strategic games the solution generated by iterated application of a choice rule gives exactly the strategy profiles that might be realized by players who follow this choice rule and commonly believe they follow...

We study the collusive efficacy of competition clauses (CC) such as the meeting competition clause (MCC) and the beating competition clauses (BCC) in a general framework. In contrast to previous theoretical studies, we allow for repeated interaction among the retailers and heterogeneity in their...

Meanwhile, the Industrial Organization literature gives several reasons why retailers adopt competition clauses (CCs) such as price matching or price beating guarantees. The motivations underlying the CCs might affect their forms and spread. In this paper, we unravel the spreading pattern of CCs...

The issue of the order dependence of iterative deletion procedures is well known in the game theory community, and conditions on the dominance concept underlying these procedures have meanwhile been detected which ensure order independence (see, e.g., the criteria of Gilboa et al. (1990) and Apt...

Bonanno (Logics and the foundations of game and decision theory, Amsterdam University Press, Amsterdam, <CitationRef CitationID="CR7">2008</CitationRef>) provides an epistemic characterization for the solution concept of iterated deletion of inferior strategy profiles (IDIP) by embedding strategic-form games with ordinal payoffs in...</citationref>
