A link without an origin, I found this explanation and background to Keynesian economic analysis a few days ago, but couldn’t think of enough commentary on it to make it worthwhile. In the end I retreat to the anecdotal. I did Economics A-level at school. I was quite bad at it, and the teacher told my mother than I was bone-idle. I don’t think I’ll ever forgive him for that. I have a picture somewhere of Ben and Julian standing by the window with teenage hair and school-uniforms. And even if I lost the photo, the image would stick in my head regardless.
