Increasing the growth of agricultural productivity has become a policy priority in several OECD and non-OECD countries. Productivity for the aggregate agricultural sector (TFP) is now a key policy performance indicator, but our knowledge across countries is uncertain and available empirical evidence is often contradictory.A key objective of the Network is to convene experts in order to facilitate a dialogue, and the sharing of experiences and best practices aimed at developing an agreed framework for crosscountry agricultural TFP comparisons, accounting for environmentally-related outputs and inputs (EATFP).
