It was actually based on a blog post I wrote a few years ago.

Fun to turn a blog post into a full-blown scientific paper

Opinions? (PM me if you want the PDF of the full paper).

I haven't had a chance to read the paper but the results don't sound surprising. Population control would naturally be a slow mechanism and with life expectancy increasing the effect would be even slower. It is rather surprising that even a massive 'mortality event' (for want of a better term) would make so little difference.

Actually the only economic system that mandates constant growth is capitalism. Previous systems grew from greed/ambition but could, and did, remain static for quite long periods of time. That is certainly true of hunter-gatherers but also even for absolute monarchies. The Roman empire was at times static for (I think) hundreds of years.

Socialism of course promises the same. Production geared to human need and no profit motive. The issue is how to make it a working system. [Having a proletarian revolution is a country where the proletariat dominates would be a good start - it was only 5% of the population in Russian and probably less in China and Cuba.] However, given what a fraught and emotional topic that is, I plan to leave it right here.
