Rune,

I really like the idea of showing oil income/expendetures as a function of GDP for each nation. That plot might have serious explanatory power.

And thanks in general for all of your charting work. I love seeing the new ideas you present in plots. It's inspiring for my own efforts.

Jon,

Thanks for your comments. It is much appreciated.

I planned this post as a series where at the end I would show how much the total oil bill (as a percentage of GDP) was for some countries for the years 1980 - 2007.

If you then add in the costs from use of other energy sources, costs of food, looks on interest on debts and debtpayments etc. it hopefully could help further explain why there will be limits to how much oil prices can go up and down.
