Joint Implementation to Curb Climate Change Book

This has a bit more to it than the usual economics for non-economists book: it goes in to more detail and although aimed at beginners it covers university level concepts albeit in a non-mathematical, theoretical way. Possibly for the novice some parts may move quickly but this would be an excellent companion for the A-level student interested in getting on top of the concepts before going to uni or as a refresher for someone that has already studied the subject. There's a good description of the difference between Keynesian and classical approaches to macroeconomics here.
