In Simple Words
Compare two local job markets: heavy construction requiring physical lifting, and agricultural seed sorting requiring manual patience. Men have higher-paying outside opportunities in heavy physical labor, raising the wage they demand for sitting down to sort beans; women, whose routine domestic tasks align closer with manual sorting precision, hold a comparative advantage in detailed sorting and accept lower base pay.
Casual workers sorting beans in rural Malawi
- Men
- Comparison group
- Women
- 0.76 more units sorted per day
Observed group averages, not a randomized gender effect. One unit is about 800 grams. Differences do not prove that outside jobs caused the gap.

Explaining why female casual laborers outperform male laborers in manual sorting tasks while accepting lower baseline reservation wages in rural agricultural economies.
Participants
N = 689 rural Malawian casual laborers (66.5% female, 33.5% male) across 1,875 daily decisions.
Study Design
Field experiment measuring productivity and reservation wages using random-effects regressions with extensive individual demographic controls.
Results
Women sort 0.76 more units per day (p < 0.01), commit 0.16 fewer errors per unit (p < 0.01), and accept reservation rates 2.3 to 3.0 MWK lower than men (p < 0.01).
Takeaway
Align task assignments with gender-differentiated comparative advantages rather than assuming uniform productivity across agricultural tasks.
