Components of agricultural productivity change: Replication of <scp>US</scp> evidence and extension to the <scp>EU</scp>

Increasing agricultural productivity is a policy priority in many countries. O'Donnell (Am. J. Agric. Econ. 94(4): 873–890, 2012) decomposed change US agriculture using Lowe total factor (TFP) index. We replicate the original study, assess its robustness to alternative TFP indices, and extend analysis EU agriculture. consistently find that growth mainly driven by technical progress. In agriculture, less pronounced, both efficiency contribute changes. magnitude of measured varies across highlighting need rely on multiple indices for robust recommendations.
