Another interesting SciFi exploration of economics is the Unincorporated Man (https://www.goodreads.com/book/show/4025200-the-unincorporat...). Everyone is incorporated at birth, and trades shares in themselves (paying dividends once they are earning) to advance in life. People who don't have majority of themselves can't make their own decisions.
I liked the idea, but didn't enjoy the book. It was frustrating to see concepts only partially explored. For example: Apparently nobody in the civilization thought of using non-voting shares.
I thought that the concept was interesting, but their implementation was really boring and lackluster. It's been a while since I read it, but I felt that they didn't explore the implications of everyone's incorporated or how we got to that state as much as they probably should have.
I couldn't even finish the second book because it didn't even have the interesting bits about people being incorporated, it was just a poorly written sci-fi war novel.
