Johansson-Stenman, Olof. 2005. “Global environmental problems, efficiency and limited altruism.” Economics Letters 86:1: 101-106.
Global environmental problems are often assumed to imply extensive inefficiencies since there is no global authority corresponding to the government at a national level.
This paper shows, on the contrary, that rich countries in a free unregulated market may still undertake globally efficient abatement investments, given the existence of limited non-paternalistic altruism.
