A detailed lesson covering the key theory behind market failure. The lesson covers what is market failure, the main causes of market failure and the results of market failure. The lesson also looks at allocative efficiency and how it links to the market failure. The lesson then looks at how governments may try to intervene and fix market failure. I have also included a fun 'You Say We Pay' game to help re-cap on key topics from the lesson and linked lessons. I have also included a nice market failure bingo game to help make the lesson more interactive and fun. I have included a student copy of the lesson to go alongside the main PPT. A perfect lesson for Economics.
