Competition between companies is the fundamental mechanism of market economy. It fosters innovation, reduces manufacturing costs, and improves performance of the entire economy. Only the firms stimulated by competition can offer products and services that are competitive in terms of quality and price. This is especially important to the consumer, because intense competition allows him to choose from a larger selection of goods at lower prices. It is a simple, but very effective guarantee that the quality and price of products and services are at their optimal levels. Effective market competition is the main driving force behind overall competitiveness and economic growth. It is particularly effective when the market is formed by independent companies exposed to competitive pressures. To ensure that the suppliers are capable of exerting these pressures, the law identifies certain prohibited practices that are capable of restricting competition. These practices are then targeted by the antimonopoly office, with the primary objective of eliminating their adverse effect on competition.
