Resale price maintenance refers to an act whereby a business entity that produces or sells products sets prices for each stage of transaction in advance and forces other businesses that resell those products to sell them at the specified price or to make transactions under binding terms and conditions. (Subparagraph 20, Article 2 of the the Monopoly Regulation and Fair Trade Act)
It can be exemplified by an act whereby a manufacturer sets the wholesale or retail prices in advance and force other businesses to sell the products at the specified prices.
In general, businesses at each stage of transaction (for example, retailers or wholesalers, etc) voluntarily determine the price at which the products are sold. If the practice of resale price maintenance takes place, it would undermine the free price determination right of business entities and competition in the distribution stage.
In addition, the practice of resale price maintenance creates the same effects as the practice of price fixing between sellers in terms of impact on the entire market, thereby undermining the efficiency of distribution networks and competition between manufacturers, which will limit consumers' choices. The practice is also known as “vertical collusion”, which is distinguished from general “horizontal collusion” that takes place between competing business entities.
