The OECD TSE, which is the sum of PSE, GSSE and transfers from taxpayers to consumers, drops by 17%, from USD 409 billion in the 2013 report to USD 342 billion in this report. Most changes occur in the US estimates, which are reduced by 91% for the GSSE and 48% for the TSE, while in other OECD countries, variations in estimates between the two reports range between -12% and +5% for the GSSE, and -5% to +6% for the TSE (Table 1.A2.2). The most frequent changes in GSSE are found in expenditure on agricultural knowledge transfer and reflect the fact that expenditure on agricultural education are now fully included in the measure of policy effort, while in the previous methodology, expenditure on students, which did not remain in the agri-food sector, was excluded. While a new expenditure item was added in the inspection and control category (for farm input), numbers change only marginally in most countries.
