Book excerpt: This annual report monitors and evaluates agricultural policies spanning all 6 continents, including the 36 OECD countries, the 6 non-OECD EU Member States, and 12 emerging economies. It is a unique source of up-to date estimates of support to agriculture using a comprehensive system of measuring and classifying support to agriculture – the Producer and Consumer Support Estimates (PSEs and CSEs), the General Services Support Estimate (GSSE) and related indicators – which provide insight into the increasingly complex nature of agricultural policy and serve as a basis for OECD’s agricultural policy monitoring and evaluation.
