Merger simulation is growing in importance as a tool to evaluate the unilateral competitive effects of mergers. This paper offers a relatively non-technical description of the principles of merger simulation. In addition, it introduces PCAIDS, a new and highly flexible "calibrated-demand" merger...

We present a method to calibrate empirically the demand parameters in a merger simulation model by using brand-level profit margin data. While the approach can be generalized, we develop these ideas within an articular framework - the PCAIDS (proportionality-calibrated AIDS) model. We show that...

This Article provides a framework for the analysis of the potential effects of the recent AOL/Time Warner merger on the markets forbroadband Internet access and broadband Internet content. We consider two anticompetitive strategies that a vertically integrated firm such as AOL Time Warner,...
