This is the abstract of the paper (source):
Using household survey data from Sauri Millennium village and propensity score matching methodology, this paper sought to analyze the impact of the Millennium Village Project (MVP) interventions on agricultural productivity and income. The results show a significant increase in agricultural productivity and an insignificant income effect, which can be attributed to small land sizes and over-reliance on agriculture. The results indicate the need to diversify economic activities and a revision of the assumptions on the relationship between productivity and income, on which the MVP, and many other rural development policies, rely on.

The discussion is gonna get really interesting . . . I wonder what Chris Blattman will think of it.
