A randomized experiment that measures the impact of a social policy in a sample of the population reveals whether the policy will work on average with universal application. An experiment that includes only the subset of the population that volunteers for the intervention generates narrower "proof-of-concept" evidence of whether the…

This research critically analyzes the introduction of the Express Entry system in Canada, requiring foreign nationals to submit an Expression of Interest (EOI) and wait for an invitation before being allowed to apply for permanent residence. Drawing on available empirical data, I argue that this reform jeopardized international students' chance to…

This paper exploits a source of variation in the eligibility for federal nutrition programs to identify the program effects on food insecurity. Children are eligible for the WIC [Women, Infants and Children] program until the day before they turn 61 months old. The result is an age discontinuity in program participation at the 61-month cutoff.…

Workers in STEM (science, technology, engineering, and math) fields play a direct role in driving economic growth. Yet, because of how the STEM economy has been defined, policymakers have mainly focused on supporting workers with at least a bachelor's (BA) degree, overlooking a strong potential workforce of those with less than a BA. This report…

Under the federal No Child Left Behind Act, schools were held almost exclusively accountable for absolute levels of student performance. But that meant that even schools that were making great strides with students were still labeled as "failing," just because the students had not yet made it all the way to a "proficient" level…

This article examines the power analyses for the first wave of group-randomized trials funded by the Institute of Education Sciences. Specifically, it assesses the precision and technical accuracy of the studies. The authors identified the appropriate experimental design and estimated the minimum detectable standardized effect size (MDES) for each…

Testimony on the need for building an information base on the changing demographics of an aging society in order to make intelligent policy decisions is presented in this Senate committee hearing. Opening statements by Senators Charles Grassley and John Glenn are provided. Jacob A. Brody, dean of the School of Public Health, University of Illinois…

Analysis of data from the 1971 Public Employment Program (PEP) showed that PEP job requirements still favored male workers and that, after the program, wage differentials reverted to pre-PEP levels. (MF)

Asserts that policymakers and the general public should be well informed about economic and social issues. Contends that a statistical system in a democracy has a heavy responsibility to ensure that the data represent fact, not opinion. Discusses changes made in the Consumer Price Index to prevent it from becoming politicized. (CFR)

Structural equation models of annual federal expenditures for elementary and secondary education and for higher education were estimated using time-series data extending from 1947 to the later 1970s. The pattern of expenditures for elementary and secondary education proved to follow closely that for higher education. Factors affecting federal…

Comparison of federal need-analysis formulas for student financial aid in 1992-93 and 1993-94 focused on elimination of home/farm equity from calculations, parent contributions, and Pell Grant awards. Results suggest higher unmet need and lower Pell Grant awards, and imply that the most needy students may lose gift assistance to more affluent…
