“…A large collection of microeconomic studies attempting to determine the income links to nutrition through specific mechanisms provide mixed and often conflicting results. The investigated mechanisms include (i) commercialization (reviewed by DeWalt, 1993 , Kennedy et al, 1992 , Von Braun and Kennedy, 1994 ), (ii) gender dynamics (reviewed by Kurz and Johnson-Welch, 2007 , Peña et al, 1996 , Quisumbing et al, 1995 , Quisumbing and Maluccio, 2000 ), and (iii) nutrition-sensitive production and education interventions (reviewed by Berti et al, 2004 , Gillespie and Mason, 1994 , Leroy and Frongillo, 2007 , Masset et al, 2011 2 ; Ruel, 2001 , Soleri et al, 1991 ). While some differences could be due to context-specific dynamics, numerous reviews in recent years express concerns regarding (i) the validity of the empirical methods used for impact estimation, and (ii) the inconsistency in the types of data used across studies which often lack information on income and have information on only consumption or anthropometry but not both ( Arimond et al, 2011 , Leroy et al, 2008 , World Bank, 2007 ).…”
