In this GCSE Economics lesson, we explore the Oligopoly market structure, one of the most fascinating forms of imperfect competition. You’ll learn what an oligopoly is, its key features, and how a few dominant firms control the market through price rigidity, collusion, and non-price competition. We’ll also discuss real-world UK examples such as supermarkets, mobile phone providers, and fuel companies — helping you understand how oligopolies affect prices, output, and consumer choice. By the end of this lesson, you’ll be able to: • Define Oligopoly and identify its characteristics. • Explain how firms behave under price competition and collusion. • Understand non-price competition (branding, innovation, advertising). • Analyse how oligopolies influence market efficiency and consumer welfare. This lesson is part of the GCSE Economics Market Structures series, covering Perfect Competition, Monopolistic Competition, Oligopoly, and Monopoly. It’s ideal for students preparing for AQA, Edexcel, or OCR GCSE Economics exams. Thank you for listening to Mr. G. Please like, subscribe, and comment.
