Competition Bureau releases an analysis of its approach to retail mergers

September 15, 2014 — OTTAWA, ON — Competition Bureau

Today, the Bureau released a white paper written by its T.D. MacDonald Chair in Industrial Economics, Renée Duplantis, which provides an analysis of the economics tools and techniques the Bureau uses when investigating retail mergers.

While every acquisition is unique and each Bureau investigation is tailored to the specific facts and evidence relating to that particular merger, the Bureau usually relies on a common core of economic tools when analyzing retail mergers. The paper discusses the Bureau’s approach to the analysis of the downstream “retail to consumer” and upstream “wholesale to retailer” portions of a retail merger.

The paper also discusses the techniques the Bureau uses to define the relevant product and geographic markets and addresses how the Bureau estimates the competitive effects that a particular merger could have on the market and on consumers.
