A theoretical framework Lucas‘ (1988) growth model: Production function: Human capital definition: Accumulation rule: Euler equation:
A tentative decisiontreefor human capital Problem: Low levels of human capital investment High cost of finance Low returns to education Skill mismatch Low demand for skilled labor (brain drain) Lack of access to (public) finance for education Problems in school access and/or infrastructure Supply-side factors Demand-side factors

Estimating returns to education • Mincerian wage regressions, where X contains variables summarizing characteristics of the individual (age, experience, gender, education) and the firm (sector).
Estimating returns to education • Mincerian wage regressions, • Education in wage regressions: • „Yearsofeducation“: Averagereturntoeducation. • Nodistinctionbetween different attainments. • Potential nonlinearities. • Educational attainmentlevels. • Comparabilityissues. • Probablymorehelpfultoidentifybottlenecksandconstraints. • Interaction termstoassessdifferencesacrosssocialgroups. • Differences male/female. • Quantile regressionstoassessdifferencesacrosspartsofthe wage distribution.
Estimating returns to education • Zambia: Productivity and Investment Climate Survey 2007 (Employee questionaire) • Data on over 900 employees for 153 enterprises. • Personal characteristics: age, gender, previous experience, job experience, … • Education information: • Years of education. • Educational attainment: Primary, secondary general, secondary technical, vocational training, university first degree (domestic/foreign), university second degree (domestic/foreign).
Estimating returns to education • Parameters differacrossquantiles, wherebq is the parameter vector associated with the q-thquantileoftheconditionaldistributionofthe wage variable.
Estimating returns to education • Differences in returns to education: • Across educational attainment levels. • For women/men. • Across quantiles of the conditional distribution of wages. • Constraints on the supply side? • Vocational training and tertiary education receive relatively high returns. • Technical versus general secondary schooling. • Much higher returns in higher quantiles of the conditional distribution of wage levels.
Migration patternsbyeducationandgender • Brain drain versus labour migration. • „Feminization“ of the brain drain. • Relatively low levels for African standards. • Lack of statistics and monitoring. • Particularly important for the health sector.
The labour demand side • Skill of labor force is not reported as an important constraint by firms, although • Domestic firms report it to be more of a problem than foreign firms • Self selection? • Wage competition? • Exporting firms report it to be more of a problem than non-exporting firms • Medium-sized firms report it to be more of a problem than small and large firms
