Development & Human Capital
• Economic growth would not lead to substantial
increases in investment in children’s education
and health
• Better educated mothers tend to have educated
and healthy children
• Market failure in education and health requires
policy action

Determinants of Education Demand
• Wage or income differential paid to workers
with various levels of education
• Probability of success in finding a job in the
formal sector
• Direct private cost of education (e.g., tuition)
• Indirect or opportunity cost of education (i.e.,

Return of Investment in Education
• Initial investments in education lead to a
stream of higher future income
• The present discounted value of this stream
of future income is compared to the cost of
education

Child Labor in LDCs
• Some 120 million children work full-time
• Some 150 million children work part-time
• Of these 250 million working children
– 61% or 153 million in Asia
– 32% or 80 million in Africa
– 7% or 17 million in Latin America

Child Labor in LDCs
• Child labor is a common practice in LDCs
labor markets
• The problem may be modeled using the
“multiple equilibria” approach
• Government intervention is needed to move
to a ‘better’ equilibrium

The Education Gender Gap
Females receive less education than males in LDCs. To close the gap

• The rate of return on education is higher for female than male
• Female education increases productivity and lowers fertility
• Educated mothers raise educated children
• Female education helps break the vicious cycle of poverty and
inadequate schooling for women

Social vs. Private Returns of Education
• Social and private returns of education are
higher in LDCs than MDCs
• Private returns are higher than social returns

Optimal Level of Education
• Optimality criterion for education: maximum
difference between returns and costs
• Social: the optimal level of education is “primary”
where costs are subsidized and returns are high
• Private: the optimal level of education is “higher”
where costs are heavily subsidized and returns are
very high
