What is meant by 'limiting or controlling production' according to competition law?

Limiting or controlling production refers to practices where companies intentionally restrict the quantity of goods produced in order to manipulate market prices. By reducing the supply of a product, these firms can create an artificial scarcity, which often leads to higher prices for consumers. This practice is scrutinized under competition law, as it undermines the principles of a free market where prices should be determined by supply and demand dynamics rather than collusion or anti-competitive agreements among producers. In this context, the focus is on how reducing output adversely affects market competition and customer choice, which is fundamental to a healthy economic environment.

The other options, while they may relate to production in some way, do not capture the essence of what is meant by limiting or controlling production within the framework of competition law. Increasing efficiency, improving quality, and enhancing competition through innovation are generally seen as positive practices that contribute to market health, rather than actions that would be considered anti-competitive.
