Associated legal terms
Relevant market
Identifying the relevant market is the process of market definition that is necessary for all forms of competition analysis, whether assessing dominance, agreements or merger review. The relevant market identifies the focal product, relevant geographic area and time-frame and lays the foundation for identifying the competitive constraints acting on a supplier, particular product or service.
Selective distribution
A system whereby only appointed distributors and retailers are permitted to purchase and resell the producer's goods.
Unilateral effects
Unilateral effects can arise in a situation where as a result of the merger, the merged firm can profitably raise prices due to the loss of competition between the merged entities. Evidence or indicators of the likelihood of unilateral effects can lead to a merger being prohibited.
