Describe the findings in the study in our readings on how teacher quality has changed over time (Corcoran - "Long-Run Trends in the Quality of Teachers"). In describing the findings make sure you mention how teacher quality is measured and what has happened to this measure over time. Explain why higher productivity in other professional fields may lead teacher salaries to increase even if teacher productivity is flat or falls. In his handbook chapter ("School Resources"), Hanushek provides evidence that the US lags behind other developed countries in terms of student performance, despite higher spending on education.
