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.
