The Malawi Farm Input Subsidy Program (FISP) was praised for turning the country's food deficit into a surplus immediately after its inception in 2005. It is, however, not clear whether these food security gains spillover to equity in distribution of welfare. In this study we examine the effects of the FISP on per-capita consumption convergence, using a sample of 2251 households interviewed in the 2010 to 2013 Malawi Integrated Household Panel Survey. The analysis employs a Lewbel method of instrumental variables (IV) to account for the potential non-random selection into the FISP. The results reveal that FISP helps relatively poor farmers increase household percapita consumption towards converging to that of the relatively rich. This convergence is robust only amongst small but not large farmers. Past studies that evaluated the FISP while not paying attention to the welfare equity gains in household per-capita consumption, may have underestimated its benefits. Policy, should, therefore, support the FISP with an additional objective of reducing inequality, beyond the primary aim of enhanced food security. Considering that the effects of FISP are limited to small farmers, alternative interventions such as inputs for credit should be made available to large farmers. This will allow the FISP induce widespread welfare gains.
