The introduction is welldone, but it could be improved in some points. I have missed a review of the literature. The measurement of the agricultural labor productivity is an important theme in the literature, not only in the agricultural economics, but also in the economics literature. For example, there are two paper published in two important journals in economics recently that the authors omitted. These papers could be reinforcement about the relevance of this measurement of agricultural productivity: Gollin D, Lagakos D, Waugh ME (2014) Agricultural productivity differences across countries. American Economic Review 104(5):165–170; Gollin D, Lagakos D, Waugh ME (2014) The agricultural productivity gap. Quarterly Journal Economics 129(2): 939–993.
