The Nominal Assistance Coefficient (NAC) of 1.23 indicates that total gross farm receipts in the OECD area were on average 23% higher in 2011-13 than if they were generated at world market prices and with no budgetary support - a differential that has narrowed significantly since 1986-88, when it was 59%. With higher world prices, policies to support domestic prices in OECD countries generated smaller transfers, resulting in the overall reduction in support to producers. Support to producers fell significantly in Israel and Canada, where the decline reached about 2 and 3 percentage points respectively, and in Iceland, Norway and Switzerland, where the decline was above 6 percentage points. Compared to the previous year, support in 2013 increased significantly in Korea.
