I've always been a bit of a student of economics (spent 3 years of studying it in school plus it's a hobby).

And this paper has got to be the most concise explanation of elementary economics I've ever seen. It covers most of the material from the first two semesters of macroeconomics and first two of microeconomics - but with far more clarity and insight.

I particularly found the explanation of Gresham's law to be the best I've seen...

nice deviation from the community norm. well played sir.
