Income Elasticity of Education Demand
When households offset public school grants by reducing private spending, policymakers worry families are behaving irrationally or underinvesting in child human capital.
Picture this
When a school provides free learning materials, families treat the saved money as additional household income. Because families have many competing needs (such as food, health, and home repairs), they spend a small portion of the extra income on education and reallocate the rest to other essential living needs, behaving as rational consumers with luxury-good preferences.
What the evidence says
The observed 76% private expenditure offset yielded an estimated income elasticity of education spending between 1.8 and 4.6, confirming that education acts as a luxury good and families reallocate funds rationally across household budget lines.
- Who
- 200 primary schools and matched households in rural Andhra Pradesh, India (~37,004 student-year observations).
- How
- Utility-maximizing household optimization model calculating implied income elasticities from experimental spending crowd-out parameters.
What to do
Incorporate non-education household budget preferences and implied income elasticities when modeling consumer response to in-kind public education transfers.
From the source
"The data suggest that parents are not behaving irrationally, and that the extent of the offset yields an estimate of income elasticity of education spending between 1.8 and 4.6..."
