In Simple Words
Imagine a small bakery that packs ten bakers inside a tiny kitchen but can only afford enough flour to bake two loaves of bread a day. The bakers spend most of their time standing around idle because flour is too expensive, even though buying an extra dollar of flour would yield four dollars in fresh bread revenue.
Research question
Smallholder farms exhibit severe allocative inefficiency across factor markets due to credit and cash liquidity constraints, resulting in underutilization of yield-enhancing cash inputs alongside excess family labor.
Participants
N = 2,232 rural smallholder households across 120 Kebeles in Amhara, Ethiopia (2011 baseline survey).
Study Design
Instrumental variables (IV) Cobb-Douglas crop production function estimation with Kebele-fixed effects, comparing the Value of Marginal Product (VMP) to Marginal Factor Cost (MFC).
Results
The marginal product of purchased cash inputs is 4.5 (statistically different from market price 1.0 at p < 0.05), indicating severe input underuse. The marginal product of labor is 484 Birr/month versus a market wage of 1,176 Birr/month (p < 0.01), indicating surplus family labor.
Takeaway
Inject targeted liquid credit or input subsidies to enable smallholders to scale cash inputs until the value of marginal product equals marginal factor cost.

- Baseline
The starting measurements in a study. Researchers use these to compare what participants were like at the start with what happens later.
ExampleBefore a training programme starts, researchers measure workers’ earnings. That first measurement is the baseline.
