I estimate a marginal abatement cost (MAC) curve using detailed, project-level data from the global phase-out of ozone depleting substances (ODSs) across 145 low-income countries, including China, Brazil and India.<\/p>\n
The data cover an estimated 85 per cent of the ODSs by weight phased out by these countries. Exploiting a quasi-natural experiment in the implementation of the Montreal Protocol, I find that average project unit abatement cost fell in the initial period of the phase-out before eventually rising, forming a convex curve overall.<\/p>\n
One explanation for this, which test, is that pre-existing technology possibilities that could be adapted the phasing out ODSs, flooded into the abatement arena in the early years, pushing down the cost of abatement through a kind of meta-learning. Holding the appearance of these new technology “possibilities” constant, I also find that each repeat “application” of each possibility associates with lower abatement cost, as through a learning-by-doing effect.<\/p>\n
These findings elaborate the theoretical basis for predicting how the cost of abating greenhouse gasses (GHG) may change over time, including why the cost of abatement now is so low.<\/p>\n
