To analyze the effect of health on work, many studies use a simple self-assessed health measure based upon a question such as "do you have an impairment or health problem limiting the kind or amount of work you can do?" A possible drawback of such a measure is the possibility that different...

This paper was prepared for a session of the 2009 American Economic Association meeting devoted to examining the views of American economists about the euro and the European Economic and Monetary Union on the tenth anniversary of the euro. I had written an article in 1992 in the Economist and...

We estimate the impact of district-level schooling mode (in-person versus hybrid or distance learning) on test scores. We combine Spring 2021 state standardized test score data with comprehensive data on schooling in the 2020-21 school year across 12 states. We find that pass rates declined...

We investigate learning at the workplace. To do so, we use German administrative data that contain information on the entire workforce of a sample of establishments. We document that having more highly paid coworkers is strongly associated with future wage growth, particularly if those workers...

This paper uses data from 10 at-scale field experiments in four countries to estimate the effect of inquiry- and problem-based pedagogy (IPP) on students' mathematics and science test scores. IPP creates active problem-solving opportunities in settings that provide meaning to the child. Students...

To help first- or second-year graduate students in economics apply their theoretical training, this paper shows how to solve a simple and intuitive computable general equilibrium (CGE) model using a calculator. Because this simplified Harberger model uses Cobb Douglas functional forms for...

Motivated by the quantitative and qualitative analysis of these early attempts, we adapted the approach and designed large-scale experiments in the states of Haryana and Uttar Pradesh to test two new scale-up models. In Haryana, teachers received support from government resource persons trained...

Education officials often use one assessment system both to create measures of student achievement and to create performance metrics for educators. However, modern standardized testing systems are not designed to produce performance metrics for teachers or principals. They are designed to...

High-dosage tutoring is an effective way to improve student learning (Nickow et al., 2024; Guryan et al., 2023). Finding ways to deliver high-dosage tutoring at large scale remains a challenge. Two primary challenges to scaling are cost and staffing. One possible solution is to reduce costs by...
