I did, however, skim through this one and found it interesting: http://www.awi.uni-heidel...20papers/papers/dp427.pdf
It uses a model with a couple of different key variables regarding industry and population types, and where taxes/subsidies can internalize the costs/benefits of both industrial pollution and fertility. It concludes that in one kind of model (probably more similar to developing countries, with "dynastic households") too much fertility is indeed a bad thing. But in another kind of model (one more similar to the western world, with "micro households") the end result is ambiguous.
I find that interesting because I had assumed, if we could take infrastructure and eco-system for granted, then maybe a bigger population would be better. The model doesn't support this idea... but it doesn't deny it either. Basically the system becomes too complicated, with too many market interactions, to reach a conclusion. Even if we could support and care for more people in an ecologically sustainable way, it still doesn't follow that more is better... it may or may not be.
At any rate, neither model is supposed to be strictly realistic but instead represent different mathematical extremes. Given the real world failing ecosystem and struggling infrastructure, more population seems to lead to suboptimal outcomes for most agents.




What have you done to save the world? You've certainly done your share of the
But are you moved to create some new
technology that will improve our global lot? Have you pursued anything like that? If not, why not?
