Current Research Projects
Affordable daycare to empower indian women
(with Arijit Nandi)
There are structural barriers to women’s empowerment in India. Among these barriers is the lack of affordable and reliable day-care services. The responsibility of providing childcare is imposed primarily on women and contributes to gender inequalities experienced by women over the life-course. The provision of affordable and reliable day-care services is a potentially important policy lever for empowering Indian women. Access to day-care might reduce barriers to labor force entry and generate economic opportunities for women. However, empirical evidence concerning the effects of day-care programs in low-and-middle-income countries is scarce. We propose a cluster-randomized impact evaluation for estimating the effect of a community-based day-care program on empowerment, economic opportunity, and health among mothers living in rural Rajasthan, India. This interdisciplinary research initiative will address an important research gap and has the potential to inform policies for improving the day-care system in India in ways that promote inclusive economic growth.
The video below provides some additional details about the project and some essential context for where this work is being done.
Using Natural Experiments to Evaluate the Impact of Population Health Interventions on Health Inequality
(with Erin Strumpf and Jay Kaufman)
A wide range of public health policies and population health interventions have been implemented with the goal of improving population health. The extent to which the causal effects of these policies have been measured is uneven, and little to no attention has been paid to their effects on vulnerable population groups. These interventions and policies are likely to affect individuals of different socioeconomic status differently, thereby reducing or magnifying existing differences in health behaviours and health outcomes. This project, newly funded by the Canadian Institutes for Health Research, will apply innovative analytic methods to measure the causal impacts of several population health interventions on health inequalities.
Impact Of Reproductive Health Restrictions On Women’s Health Outcomes
(with Nichole Austin and Erin Strumpf)
Abortion rates have been steadily decreasing in both Canada and the US, but the cause remains poorly understood. In the US, where reproductive health policies vary considerably from state to state, abortion opponents credit a recent upsurge in state-level abortion restrictions (including mandatory waiting periods, mandatory counseling, and provider licensing requirements), while advocates argue that the decline is due to empowering initiatives, such as improved access to contraception and sex education programs. Existing research, particularly on restrictions, is largely descriptive; this prevents us from understanding the causal effects of, and potentially complex interplay between, restrictive and empowering policies on abortion rates. Disentangling the effects of these factors is challenging but important, as these policies likely have a marked effect on population health. This project will bridge this knowledge gap by deconstructing the recent decline in US abortion rates and teasing apart the causal impact of empowering and restrictive initiatives. The substantial state-to-state variation in the timing of policy implementation in the US will permit the use of quasi-experimental study study designs to minimize confounding. Abortion is a common and safe medical procedure, but abortion policy decisions are currently being made with low quality evidence on effectiveness or long-term health implications. This work will ultimately provide a better understanding of why abortion rates are declining, which is vital in informing future policy decisions.

Past RESEARCH PROJECTS
Measuring Health Inequalities
The general objective of this project, funded by the Canadian Institutes for Health Research, is to identify the role of value judgments in the generation, presentation, and interpretation of health inequalities information. More specifically, the aims of this project are:
- To investigate and describe how the use of particular inequality measures may implicitly embed value judgments in data, through an empirical analysis of published health inequalities research.
- To investigate how individuals’ moral evaluations of health inequalities may be influenced by contextual factors in the presentation of data through controlled experimental research.
For more information, see the project website.
Modelling the Effects of Interventions on Health Inequalities
The Simulation Technology for Applied Research (STAR) team brings together university and government scientists, policymakers and administrators interested in the application of computer simulation technology to the assessment of health interventions and policies. Funded by a New Emerging Team (NET) grant from the Canadian Institute of Health Research (CIHR), this research program responds to the growing need for comprehensive information and tools to assist policymakers in making informed choices about investments in health care, treatments, as well as public and population health initiatives with the goal of improving system-level decision making and ultimately, population health.
Effects of Self-Report Bias on Between- and Within-Country Health Inequalities in Disabilities
(with Spencer Moore and Seungmi Yang)
As people in many countries are living longer, health conditions that are not usually fatal, such as mental disorders, arthritis, and vision and hearing problems are becoming increasingly important aspects of health and well-being. We often measure these aspects of health by asking people to report on how much difficulty they have with certain activities or health conditions. However, people from different countries or from different backgrounds may interpret the same question differently. For example, asking a 25-year old and a 70-year old how much difficulty they have walking stairs may be difficult if the two individuals use different scales when thinking about their ability. This means that observed differences between countries or social groups reflect both objective differences in health and also differences in the way people interpret the questions. Recent developments in survey techniques now allow the possibility of accounting for differences in the way individuals understand questions about their health by using brief descriptions of specific health states to put everyone’s responses on a similar scale. This study will use these ‘anchors’ to provide better measures of the prevalence of non-fatal health conditions across different countries, and between gender and economic groups within countries. The findings from this study will help to provide better measures of the importance of non-fatal health conditions across the globe.

Replication is a hallmark of the scientific enterprise. I strongly support reproducible science and efforts to increase the degree of transparency in the conduct and reporting of scientific studies. Below I provide links to my (evolving) page on the Open Science Framework and to replication datasets for recent papers, posted on Harvard's Dataverse Network.
Monitoring Health Inequalities
Health Disparities Calculator
[Latest Release: Version 1.2.4 - October 29, 2013]
Developed in collaboration with the US National Cancer Institute, the Health Disparities Calculator (HD*Calc) is free statistical software designed to generate multiple summary measures to evaluate and monitor health disparities (HD). HD*Calc was created as an extension of SEER*Stat that allows the user to import SEER data and other population based health data to calculate any of eight disparity measurements.
Several of the measures included in HD*Calc are not commonly used to evaluate cancer-related health disparities. An important function of HD*Calc is to facilitate use of a range of HD measures so that researchers can explore their utility in different situations.
Cross sectional and trend data (e.g., cancer rates, survival, stage at diagnosis) categorized by disparity groups (e.g., area-socioeconomic status, race/ethnicity, geographic areas) can be used with HD*Calc to generate four absolute and seven relative summary measures of disparity. The results are displayed as tables and charts, which may be exported for use in other applications.

Decomposition of Health Inequalities
Decomp: An R-package to facilitate understanding health inequalities (via Peter Konings and Niko Speybroeck). This statistical package for the free software R enables the quantification of the contributions of determinants to socioeconomic inequality in health. You can find a short tutorial paper on how to use it here.
