This paper investigates the causal effect of high school curriculum on various student outcomes including academic … attitudes towards studying and learning. We exploit a curriculum reform in China, the implementation of which started in 2004 … new curriculum pivoted away from the old lock-step course structure where all students took the same courses and only …

We study an intensive math instruction policy that assigned low-skilled 9th graders to an algebra course that doubled instructional time, altered peer composition and emphasized problem solving skills. A regression discontinuity design shows substantial positive impacts of double-dose algebra on...

New graduates of elite MBA programs flock to Wall Street during bull markets and start their careers elsewhere when the stock market is weak. Given the transferability of MBA skills, it seems likely that any effect of stock returns on MBA placement would be short-lived. In this paper, I use a...

Artificial states are those in which political borders do not coincide with a division of nationalities desired by the people on the ground. We propose and compute for all countries in the world two new measures how artificial states are. One is based on measuring how borders split ethnic groups...

Machine learning (ML) is mostly a predictive enterprise, while the questions of interest to labor economists are mostly causal. In pursuit of causal effects, however, ML may be useful for automated selection of ordinary least squares (OLS) control variables. We illustrate the utility of ML for...

A key challenge for research on many questions in the social sciences is that it is difficult to link historical records in a way that allows investigators to observe people at different points in their life or across generations. In this paper, we develop a new approach that relies on millions...

We use machine learning to better characterize low-value health care and the decisions that produce it. We focus on costly tests, specifically for heart attack (acute coronary syndromes). A test is only useful if it yields new information, so efficient testing is grounded in accurate prediction...

We develop a model to predict consumer default based on deep learning. We show that the model consistently outperforms standard credit scoring models, even though it uses the same data. Our model is interpretable and is able to provide a score to a larger class of borrowers relative to standard...
