Abstract
This study attempts to fill the knowledge gap between the cross-country analyses that explore the
links between income and nutrition without insights on micro-level determinants, and the
numerous microeconomic studies that suggest mechanisms of impact but are hindered by some
combination of small sample size, incomplete data, and questionable approaches to impact
estimation. The analysis uses the three annual waves of the Uganda National Panel Survey, and
features panel regressions of child anthropometric outcomes controlling for time-invariant childlevel
heterogeneity and other time-variant observables. The paper starts by looking at how the
outcomes correlate with short-term changes in rural household income. The impact is
subsequently differentiated by sector of income, first between agricultural and non-agricultural
sectors, and by type of agriculture. The analysis documents no impact of short-term changes in
total gross income on weight-related measures but documents positive effects on height-related
outcomes. Sector-differentiated analyses indicate that only the share of income originating from
non-farm self-employment exerts positive and statistically significant effects on both height and
weight measures. For height, the income shares pertaining to (i) consumption of own crop
production and (ii) low-protein crop production appear to be underlining the negative effect of
the share of income originating from crop production. The results suggest stickiness of crop
production to own consumption, and while this may be nutrition-supporting in some contexts,
income growth in the production of low-nutrient crops in Uganda may crowd out consumption of
other goods and services that have the potential to serve as better nutritional investments.
