Very interesting! Though I wasn't watching closely I think I saw a real-world example of your concept on (I think) BBC News yesterday. Forgive me if this is not wholly accurately retold:
It was about about unsustainable fishing on a large trawler that could set out about a million fishing hooks a day, and catching everything.. large tuna, sharks, etc. They then projected globally; this is the dominant way we go about fishing, and with it halfway this century our oceans will be empty of fish.
Then they brought the example of - I believe - Irish fishermen, who some years ago and seeing hugely diminishing returns, decided on a different system whereby scientists would determine beforehand the minimum shoal size that would lead to sustainable growth of the fish population. The fishermen would then be free to catch the remainder of the population, and divide it amongst themselves based on stake in the game.
This 'share' determines their yearly quota. If next year the total shoal population had grown, their 'share values' had increased. This modern fishing method apparently worked perfectly, and every year they have bigger returns, catching almost as much as in 'old times'.
