IES would like to congratulate and thank David Card, Joshua D. Angrist, and Guido W. Imbens, who received this year’s Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel. The work of these laureates has greatly contributed to the ability of researchers to provide causal evidence in support of education practice and policy decision making. IES is proud to have previously supported Card and Angrist in some of their education research work.
Many key issues in education cannot be analyzed using randomized experiments for practical and ethical reasons. Card’s work (with Alan Krueger) on natural experiments helped open up a novel approach to providing causal findings. In natural experiments, outcomes are compared for people who have differential access to a program or policy (or a change in a program or policy) because of real life conditions (for example, institutional or geographic differences) rather than through random assignment by researchers. Natural experiments have been adopted by IES grantees to examine a broad variety of education programs and policies such as PreK expansion, early literacy, school choice, school turnaround programs, high school curriculum change, and changes to postsecondary remediation course requirements. Angrist and Imbens showed how to estimate a causal treatment effect when individuals can choose to participate in a program or policy, which often occurs in natural experiments and can occur in randomized experiments after researchers have randomly assigned participants. IES grantees widely use their instrumental variable approach for both experimental (often involving designs based on school lotteries) and quasi-experimental designs.
In addition to developing evaluation designs and methods that have been broadly applied within education research, Card and Angrist have also directly carried out education research important to the field, sometimes with the support of IES. For example, Card is a principal investigator (PI) on two IES-funded studies on gifted education (elementary school and middle school) and is a co-PI on the National Center for Research on Gifted Education. Angrist is PI on two IES-funded studies, one on charter schools and one evaluating a Massachusetts desegregation program.
Angrist and Imbens have also supported the work of IES. Both researchers served as IES peer reviewers on grants and reports, and Imbens provided the What Works Clearinghouse with advice on standards for regression discontinuity designs (RDD) and co-authored one IES-supported paper regarding RDD (a method that has also become widely used in IES-funded research).
IES thanks Card, Angrist, and Imbens—both for their contributions to causal methods and for their direct participation in education research—and congratulates them for this recognition.
