Subsidy Estimation: A Survey of Current Practice
This technical manual draws together the different subsidy estimation methods that are used and have been published, mainly by intergovernmental organizations and governments. While the manual quotes multiple sources for most methods, often the approaches do not differ fundamentally, and users may simply want to refer to the one that makes most sense to them. In cases where they do differ markedly, users should choose whichever method best serves their purposes and can be implemented with the available data.
For a user-friendly introduction to the manual, explaining which methods should be used to estimate which kinds of subsidies, please see our related Policy Brief, A How-to Guide: Measuring subsidies to fossil-fuel producers.
