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...

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...
