This is one of a set of Powerpoints (and accompanying Notes/Key Terms sheets) that I have created for my own teaching of the macroeconomic topics in the new (linear) AQA AS Economics specification (7135). They follow the order of teaching recommended by the exam board and (generally) the AQA-approved textbook (Powell & Powell, 2015).
Key terms covered in this Powerpoint: (referenced to the specification):
