Price support programmes in many cases work countercyclical to markets and become inactive during high price periods. The General Services Support Estimate (GSSE) measures the associated monetary transfers. The methodology used to measure the GSSE has been revised to clarify the definition of the indicator and its components, as outlined in Box 1.3. A consequence of this revision is a more narrow definition of the GSSE which now excludes support to up-and downstream industries. The various implications by country of the more restricted definition and data improvements on the level and composition of the GSSE are summarised in Box 1.3 and with greater details in Annex 1.A2. This definition is narrower than the one applied previously because it now excludes support to services for which primary agriculture is not the main beneficiary.
