Note: MP and AP estimates come from the Fixed Effects model corresponding to column 5 in table 2. MP is calculated for each household using sample values. AP is calculated as the difference between the estimated difference in yields resulting from zero fertilizer and yields resulting from 200 kg ha-1 of nitrogen (the level at which MVCR=1, on average, when using a farmgate maize-nitrogen price ratio of 0.15), with other sample values as observed.
