Most policies that target climate change – such as carbon taxes and cap-and-trade programmes – have long-term benefits but short-term economic costs. This column argues that population policies may not be subject to this trade-off. In particular, policies that reduce population growth can have a direct positive effect on income per capita as well as lowering growth of carbon emissions. Such policies could play an important role in the portfolio of actions aimed at mitigating climate change.

Comparative advantage encouraged industrialising economies to invest in human capital, while non-industrial economies experienced population growth.
