A2 Economics Diagram Checklist

I was jotting down last night a checklist of diagrams that are fairly core to our own A2 economics courses (we take AQA) - partly in response to a student who suggested that AS diagrams might suffice in the exam! Here is my checklist for A2 macro and micro - but I am sure to have missed some out so please add suggestions in the comment box! I hope this might be useful for those taking their A2 modules in January 2011
