konkurrencegrad

Konkurrencegrad is a concept used in economics and competition policy to describe the extent of competitive pressure within a market. The term, Danish in origin, can be translated as degree of competition. It reflects how strongly firms compete on price, quality, and innovation, and how easy it is for new entrants to challenge incumbents.

To quantify konkurrencegrad, economists often use market-concentration measures such as the four-firm concentration ratio (CR4) and the Herfindahl–Hirschman Index (HHI). A higher HHI or higher CR can indicate a lower konkurrencegrad. Other indicators include the Lerner index (price over marginal cost) and price-cost margins, which capture pricing power.

Konkurrencegrad depends on the number of firms, the size distribution among firms, barriers to entry, product differentiation, and strategic behavior like price signaling or collusion. A market with many small, loosely differentiated firms and low entry barriers tends to have a high konkurrencegrad, while markets with a few dominant firms have a lower konkurrencegrad.

Regulators assess konkurrencegrad when evaluating mergers, anticompetitive practices, or regulatory reforms. However, measuring competition is imperfect: data limitations, dynamic (time-varying) competition, cross-border effects, and the fact that concentration does not always translate directly into prices or welfare outcomes.
