Investing in Human Capital During Wartime: Experimental Evidence from Ukraine
Topics: Student LearningThis paper provides insights into human capital investments during wartime by presenting evidence from three experiments of an online tutoring program for Ukrainian students amid Russia’s invasion of Ukraine. Conducted between early 2023 and mid-2024, the experiments reached nearly 10,000… more →
Causal Returns to Education
Topics: Policy, Politics, and GovernanceUsing 182 estimates from 140 studies in 55 countries, this paper compares ordinary least squares (OLS) and instrumental variables (IV) estimates of the private returns to schooling. IV returns average 9.7 percent—38 percent higher than OLS—and exceed OLS in nearly 80 percent of cases, with the… more →
The Effect of Raising School Quality on Earnings
Topics: Student LearningThe evidence underscores the need to shift attention from school attainment to actual learning. While the average global return to an additional year of schooling is about 10 percent, a one standard deviation increase in test scores raises earnings by 15 percent. Studies show that including… more →

The Returns to Education over time and the Effect of COVID-19
This paper examines the effects of the COVID-19 pandemic on the returns to education in the United States. Using data from the Current Population Survey 2011-2022, the analysis reveals that, after a period of decline, returns to education increased significantly because of COVID, particularly… more →
COVID-19, School Closures, and Student Learning Outcomes: New Global Evidence from PISA
Topics: Student LearningThe COVID-19 pandemic resulted in significant disruption in schooling worldwide. This paper uses global test score data to estimate learning losses. It models the effect of school closures on achievement by predicting the deviation of the most recent results from a linear trend using data from… more →
