Subsidy Estimation: A survey of current practice

One of the key challenges of subsidy reform is a lack of consistent, internationally-comparable data. Information and guidance on how to measure subsidies is incomplete.

As a first step towards developing internationally-agreed upon subsidy estimation methods and best practice, the GSI has compiled a manual drawing together various methodologies used to calculate subsidy values. The manual takes as its starting point, the definition of subsidy in the WTO's Agreement on Subsidies and Countervailing Measures, and provides methodologies for each type of subsidy covered by the definition. These methodologies have been extracted from sources used and publicly reported by a range of inter-governmental organizations, countervailing authorities, other government agencies and non-governmental agencies.
