You might be interested in the Future of Life Institute’s AI worldbuilding competition (including my 2nd-place-winning entry), which asked people to imagine an optimistic future with AGI and includes several questions where participants detail how economies and wealth inequality have changed in a post-AGI world. (In addition to stuff about daily-life and economics, the competition also had a big emphasis on the geopolitical balance of power between nations, and how AGI will be governed.)
