HOW TO USE THIS ONLINE LESSON
Follow along in order of the activities shown below. Some are interactive game-based activities, designed to test your understanding and application of market structures and contestability. Others are based on short videos, including activities for you to think about and try at home, as well as some extra worksheet-based activities.
If you would like to download a simple PDF worksheet to accompany the video activities, you can find it here. You can print it off and annotate it for your own notes, or make your own notes on a separate piece of paper to add to your school/college file.
ACTIVITY 1: GAME - MARKET STRUCTURES CHARACTERISTICS
Review the key characteristics of the various market structures in this interactive activity.
ACTIVITY 2: VIDEO - INTRODUCTION
This video looks at the traditional market structure spectrum of competition, and considers why and how contestable markets don't fit with the traditional model
ACTIVITY 3: VIDEO - THE THEORY
In this video, we cover the nature of contestable markets in more depth, looking at the impact of low barriers to entry on output and pricing.
ACTIVITY 4: ESSAY ANALYSIS
For this activity, we'll take a look at some example essay answers on topics related to contestable markets.
Click here to read an example answer from Geoff Riley on the impact of barriers to entry on economic profit.
And click here to download an example essay accompanied by examiner commentary on rising contestability in the postal sector.
Summarise the key features (content and structure) of these essays.
ACTIVITY 5: VIDEO - WHY ARE SOME MARKETS NOT CONTESTABLE?
Here, we cover some of the reasons why some markets are unable to be contestable, for example, for reasons of high sunk costs and natural monopoly.
ACTIVITY 6: APPLIED THINKING TASK
Download this tutor2u All Change activity, which looks at some real-world business case studies and considers the ways in which those businesses have been threatened by falling barriers to entry.
ACTIVITY 7: VIDEO - MORE APPLICATION
This video covers even more real-world examples of markets that have become more contestable.
ACTIVITY 8: SYNOPTIC CONNECTIONS
Download these tutor2u synoptic assessment mats on
- the motor vehicle repair industry, and
- the British high street
Read the case study in the centre of each mat, and then have a go at the questions accompanying each case study.
ACTIVITY 9: VIDEO - POLICIES
In this final video, we look at some of the policies that governments can deploy to help make markets more contestable. Don't forget that these can often also count as supply-side policies - this is a GREAT area for making synoptic connections.
The economist William Baumol helped to develop the theory of contestable markets (amongst many other aspects of economics!). Read a brief summary of his life and work from The Economist, published shortly after he died in 2017. Carry out your own wider reading and research into Baumol's work on contestable markets.
