We study the optimal timing of merger control by comparing the pre-and post closing enforcement. Mergers have both pro- and anticompetitive effects, and the parties(the agency and the merging …firms) veri…able information on them is endogenous: it depends on the timing of the merger control,...

In this paper, we provide a theoretical framework for exploring the consequences of neighborhood informational effects ?identified as role models? so as to deduce the urban configuration. Specifically, we have developed an overlapping generations model of community formation. When young, an...

This paper aims to contribute to the normative economic analysis of mergers control by taking into account the possible efficiency gains for the design of structural merger remedies. We show that a larger asset transfer should be requested from a less efficient merged firm than from a more...

The efficiency defence was long delayed in the European merger control due to costly implementation issues. In this paper we argue that the upstream consequences of the efficiency defence should equally be considered, namely the improvement of the distribution of notified mergers through the...
