Countries provide different levels of support from public expenditures to farmers. Some countries subsidise their agricultural producers more significantly. On the other hand, other group of countries provides less support to their producers from public resources. Different international organisations and institutions provide their own indicators as in the case of the Oranisation for Economic Co-operation and Development (OECD). The OECD provides a comprehensive framework to measure the level of support and to identify its structure. This measurement provides a comparable review of support to agriculture from public budgets and helps to evaluate the transfers from taxpayers to producers or consumers. The aim of our work was to present this measurement framework, the differences in support between OECD and some non-OECD countries and to see if there is an evidence of development in level and/or in structure of supports in agriculture in the 2016, 2017 and 2018’s editions of OECD publications taken into consideration. The comparative analysis shows that not only the level, but the composition of support differes from country to country.
