Getting Started

  1. Collect data on product prices, shares, margins and diversions (optional).

  2. If you have data on many/all products in the market consider calibrating a demand system and simulating a merger with either a aids,logit, ces, linear, or loglin demand system.

  3. If you only have data on the merging parties' products, consider using cmcr.bertrand or cmcr.cournot to uncover the marginal cost reductions needed to offset a post-merger increase.
