Contracting for impure public goods: Carbon offsets and additionality

Mason, Charles F.; Plantinga, Andrew J. - 2011

Governments contracting with private agents for the provision of an impure public good must contend with agents who would potentially supply the good absent any payments. This additionality problem is centrally important in the use of carbon offsets as part of climate change mitigation....
