Are you looking for textbooks or easier reads? If you're willing to read textbooks, Mueller's Public Choice III has all kinds info and theory about policy, systems, and meta-systems from an economic perspective.
If you don't want textbooks, then read Bryan Caplan's book, Brennan and Lomasky's Democracy and Decision, and Carpini and Keeter's What Americans Know About Politics and Why It Matters, which will collectively bring you to the cutting edge of how we get policy failure on the "system" level. Read Donald Wittman's The Myth of Democratic Failure for the opposite perspective (Caplan is mostly responding to Wittman).
For "meta-system" stuff, definitely read Mancur Olson, The Rise and Decline of Nations and The Logic of Collective Action (if you only read one, read the former as it is much more "meta-system" while the latter is a bit more "system". There are excellent insights in both.)
There is a huge debate in economic history about how much political institutions matter for outcomes, mostly focusing on why Britain specifically had an industrial revolution at the time it did while other countries (especially China) did not. You can read Greg Clark's A Farewell To Alms for the anti-institutional story, many Doug North works for the standard institutional story, and a sort of sideways pull from Deirdre McCloskey's recent Bourgeois Dignity or Mokyr's The Enlightened Economy.
That's all I've got as an economist. Not much on environmentalism, but plenty on how we got what we've got, whether what we've got is good, and whether what we've got can be improved.
I've become adept at navigating the bureaucracy of my public high school. I've dropped environmental science as an AP (because it was painfully slow and replete with busywork) and am now taking an "independent study" in government. I'm going to be using this mainly as a way to study environmental science at my own pace, but I also have to read and write some about standard political issues. the requirements of the independent study are pretty vague. In order to get approved, I've got to BS some reason why I should be granted an independent study. I'm obviously not going to speak plainly. I'll probably say something about my interests in seasteading, environmentalism, and education reform. What books do you recommend on the politics of these subjects given that it is the mindkiller? Also, the main focus is on environmentalism, not on education or seasteading. I've done a bit of research regarding seasteading, but there's not much that I know about
I was particularly interested in this point brought up in the seasteading book:
They also recommend a reading list:
In regards to environmentalism, I was thinking about focusing on the relationships between government funding for green businesses as green entrepreneurship is of interest to me. I'd probably have to talk about the Solyndra scandal at some point.
As a side note, if the requirements aren't too stringent and I can just write about whatever I feel like so long as it vaguely relates to politics (like in my independent study in psychology), I may just go meta and write about Americans Elect.
Edit: I do think that there is a difference between descriptive politics ( e.g.describing the workings of the EPA or a standard civics class) and and normative (woo liberatarians!). I'm more interested in descriptive politics.
