This lesson looks at technological change and how it is impacting firms. The lesson looks at the difference between invention and innovation with relevant examples. The lesson also focuses on synergy demand and how some firms are using this to create huge profits. The lesson then looks at disruptive innovations and barriers to entry. The lesson concludes with some questions to help reflect on the key theory. I have included a teacher and student copy of the PPT. I have also included Economics Pictionary as a nice plenary game - this game includes key words to use and explains the rules. The lesson is perfect for teaching microeconomics at and could be used for Business Studies.
