What Can We Learn about Sars-CoV-2 Prevalence from Testing and Hospital Data
Measuring the prevalence of active SARS-CoV-2 infections in the general population is difficult because tests are conducted on a small and nonrandom segment of the population. However, hospitalized patients are tested at very high rates, even those admitted for non-COVID reasons. We show how to use information on testing of non-COVID hospitalized patients to obtain tight bounds on population prevalence, under conditions weaker than those usually …
Mask Mandate Costs
Mask mandates were controversial policies during the pandemic. Although there is considerable research on the benefits of masks, there has been no research on the distribution of perceived costs of compliance with mask mandates. This article presents the results from a hypothetical set of questions related to mask-wearing behavior and opinions that were asked of a nationally representative sample of over 4,000 participants in early 2022. We use s…
Disease awareness and healthcare utilization in rural South Africa
Our results suggest that older adult PLHIV may visit public clinics more often than their HIV-negative counterparts but spend similarly on a per-visit basis. This provides preliminary evidence that the positive health outcomes observed among PLHIV in rural South Africa may be explained by different healthcare engagement patterns. Through our illustrative comparison between PLHIV and diabetics, we show that shifting disease burdens towards chronic…
Determinants of Disparities in Early Covid-19 Job Losses
This study examines the sociodemographic divide in early labor market responses to the U.S. COVID-19 epidemic and associated policies, benchmarked against two previous recessions. Monthly Current Population Survey (CPS) data show greater declines in employment in April and May 2020 (relative to February) for Hispanic individuals, younger workers, and those with a high school diploma or some college. Between April and May, the demographic subgroup…

What Can Instrumental Variables Tell Us About Nonresponse In Household Surveys and Political Polls
This paper introduces an instrumental variables framework for analyzing how external factors that affect survey response rates can also affect the composition of the sample of respondents. The method may be useful for studying survey representativeness, and for assessing the effectiveness of some of the conventional corrections for survey nonresponse bias. The paper applies the method to data collected in the 2011 Swiss Electoral Study (SES), in …
Designing Difference in Difference Studies
The difference in difference (DID) design is a quasi-experimental research design that researchers often use to study causal relationships in public health settings where randomized controlled trials (RCTs) are infeasible or unethical. However, causal inference poses many challenges in DID designs. In this article, we review key features of DID designs with an emphasis on public health policy research. Contemporary researchers should take an acti…
Long-Term Weight Loss Effects of a Behavioral Weight Management Program
This study examined whether community food environments altered the longer-term effects of a nationwide behavioral weight management program on body mass index (BMI). The sample was comprised of 98,871 male weight management program participants and 15,385 female participants, as well as 461,302 and 37,192 inverse propensity-score weighted matched male and female controls. We measured the community food environment by counting the number of super…
Health Service Utilization and State Costs Among Adults Aging With Early-Acquired Physical Disabilities in Medicaid Managed Care
Objective: We evaluated the impact of Medicaid managed care (MMC) on health service use and state costs among adults with early-acquired physical disabilities. Method: Using claims data, we tracked utilization of the emergency department (ED), inpatient admissions, outpatient physician visits, and state expenditures on enrollees who transitioned to MMC ( n = 881). The inverse propensity score weight and a difference-in-differences regression mode…
Regression Discontinuity and Beyond
Treatment effect estimates from a regression discontinuity design (RDD) have high internal validity. However, the arguments that support the design apply to a subpopulation that is narrower and usually different from the population of substantive interest in evaluation research. The disconnect between RDD population and the evaluation population of interest suggests that RDD evaluations lack external validity. New methodological research offer st…
Did States Use Implementation Discretion to Reduce the Stringency of NCLB? Evidence From a Database of State Regulations
When No Child Left Behind (NCLB) became law in 2002, it was viewed as an effort to create uniform standards for students and schools across the country. More than a decade later, we know surprisingly little about how states actually implemented NCLB and the extent to which state implementation decisions managed to undo the centralizing objectives of the law. This paper introduces a state-level measure of NCLB stringency that helps shed light on t…

What Can We Learn From A Doubly Randomized Preference Trial?—An Instrumental Variables Perspective
The doubly randomized preference trial (DRPT) is a randomized experimental design with three arms: a treatment arm, a control arm, and a preference arm. The design has useful properties that have gone unnoticed in the applied and methodological literatures. This paper shows how to interpret the DRPT design using an instrumental variables (IV) framework. The IV framework reveals that the DRPT separately identifies three different treatment effect …
Workplace Compliance With the Law
Using the 2008 National Study of Employers to analyze employers' compliance with the Family and Medical Leave Act (FMLA), we show that prior studies have overestimated compliance due to the treatment of missing values and incomplete definitions of the FMLA. Using partial identification methods, we estimate that FMLA compliance among firms with 50 or more employees in the private sector is at least 54.3% and at most 76.8%. We also look at organiza…
Strengthening the Regression Discontinuity Design Using Additional Design Elements
The sharp regression discontinuity design (RDD) has three key weaknesses compared to the randomized clinical trial (RCT). It has lower statistical power, it is more dependent on statistical modeling assumptions, and its treatment effect estimates are limited to the narrow subpopulation of cases immediately around the cutoff, which is rarely of direct scientific or policy interest. This paper examines how adding an untreated comparison to the basi…
Research Designs for Program Evaluation
Over the past two decades, the program evaluation literature has made great advances on improving methodological approaches for establishing causal inference. The two most significant developments include establishing the primacy of design over statistical adjustment procedures for making causal inferences, and using potential outcomes to specify the exact causal estimands produced by the research designs. This chapter presents four research desi…
Effects of Written Informed Consent Requirements on HIV Testing Rates
Objectives. I evaluated the effects of written informed consent requirements on HIV testing rates in New York State to determine whether such consent creates barriers that discourage HIV testing. Methods. New York streamlined its HIV testing consent procedures on June 1, 2005. If written informed consent creates barriers to HIV testing, then New York's streamlining exercise should have reduced such barriers and increased HIV testing rates. I used…
