It also explores the possibility of cooperation and attainment of an optimal steady state. It is shown that the problem is similar to that in the static model (Chander and Tulkens (1997)).

Adaptation to Climate Change

We investigate the effect of climate change on population growth in 18th and 19th century Iceland.

We also find that 18th and 19th century Icelanders ada...
