*»** Teacher Quality and Cross Country Differences in Student Achievements **»*
*Abstract This paper proposes and calibrates a micro-founded theoretical
model of teacher selection for a panel of 22 OECD countries. Based on the
model, I build time series of teacher quality (TQ) for each country,
analyse its main drivers and study the importance of TQ in explaining
differences in student achievements. In equilibrium the relationship
between teacher salaries and TQ is non-lineal and maybe non-monotonic which
help us to understand the ambiguous findings in the empirical literature
between teacher salaries and student achievements. My proposed measure of
TQ is strongly positively correlated with cross-country dispersion in
student outcomes, even controlling for student and school characteristics,
family background, macroeconomic context and unobservable country fixed
effects. The counterfactual exercise shows that cross-country differences
in TQ explains approximately 22% of the observed cross-country variance in
students outcomes, its effect is quite similar to the family background
effect. Initial distributions of population skills are crucial to determine
current differences in TQ across countries, while teacher salaries and
labour market conditions are of lesser importance. *
