Large disparities remain in the rates of growth across the OECD countries

The remaining large gap in cross-country differences of relative levels of agricultural TFP across the OECD countries has aroused increasing public concerns.

The cross-sectional coefficient of variation of agricultural TFP held constant since the 1980s when globalization was making technological innovation more accessible across these OECD countries.

The remaining large gap in relative agricultural TFP levels in recent years also coincides with slowdowns in growth of agricultural productivity.
