Subsidies and Crowding Out: A Double‐Hurdle Model of Fertilizer Demand in Malawi

Abstract: This article uses a double-hurdle model with panel data from Malawi to investigate how fertilizer subsidies affect farmer demand for commercial fertilizer. The article controls for potential endogeneity caused by the nonrandom targeting of fertilizer subsidy recipients. Results show that on average 1 additional kilogram of subsidized fertilizer crowds out 0.22 kg of commercial fertilizer, but crowding out ranges from 0.18 among the poorest farmers to 0.30 among relatively nonpoor farmers.This indicates that ta… Show more

“…Second, if the FSP was disproportionally allocated to productive districts (as the FAO results suggests) these would be districts that presumably had lower levels of hunger (although they may still be cash poor). Finally, at the household level, Ricker-Gilbert et al (2011) find evidence that FSP was allocated to larger landholdings, suggesting that hunger 'need' may not have driven allocation.…”

“…An underlying assumption of the one-step approach is that the same set of variables determines both the participation and intensity stages (Alene et al 2008). This assumption is not only restrictive but erroneous since it is possible that a variable could have different effects on participation and intensity of participation (Wooldridge 2002;Ricker-Gilbert et al 2011;Olwande and Mathenge 2012). The two-step approach simultaneously or sequentially models participation and intensity, thus helping to resolve the limitation inherent in the single-step approach.…”

“…There is potential to use conservation agriculture to adapt to climate change (FAO 2009;Thiombiano and Meshack 2009;Ngwira et al 2013b;Delgado et al 2011). Ricker-Gilbert et al (2011) studied the effects of fertilizer on the production of maize in Malawi and found a residual effect since users of fertilizer in fields that were not fertilized in previous years increased their yields by 1.8 kg kg -1 (4.0 lb lb -1 ) of fertilizer applied, which was much lower than the increase in yields observed for users of fertilizer in fields that were fertilized the previous three years, who increased their yield by 3.2 kg maize kg -1 (7.1 lb maize lb -1 ) of fertilizer applied. These data suggest that there is an effect of residual N inputs due to residual inorganic N or due to N cycling in the system that is contributing to higher yields.…”
