Health and Medicine

FSI’s researchers assess health and medicine through the lenses of economics, nutrition and politics. They’re studying and influencing public health policies of local and national governments and the roles that corporations and nongovernmental organizations play in providing health care around the world. Scholars look at how governance affects citizens’ health, how children’s health care access affects the aging process and how to improve children’s health in Guatemala and rural China. They want to know what it will take for people to cook more safely and breathe more easily in developing countries.

FSI professors investigate how lifestyles affect health. What good does gardening do for older Americans? What are the benefits of eating organic food or growing genetically modified rice in China? They study cost-effectiveness by examining programs like those aimed at preventing the spread of tuberculosis in Russian prisons. Policies that impact obesity and undernutrition are examined; as are the public health implications of limiting salt in processed foods and the role of smoking among men who work in Chinese factories. FSI health research looks at sweeping domestic policies like the Affordable Care Act and the role of foreign aid in affecting the price of HIV drugs in Africa.

Join the Program on Democracy and the Internet (PDI) and moderator Nate Persily, in conversation with Meicen Sun for Internet Control as A Winning Strategy: How the Duality of Information Consolidates Autocratic Rule in the Digital Age.

This paper advances a new theory on how the Internet as a digital technology helps consolidate autocratic rule. Exploiting a major Internet control shock in China in 2014, this paper finds that Chinese data-intensive firms have gained from Internet control a 10% increase in revenue over other Chinese firms, and about 1-2% over their U.S. competitors. Meanwhile, the same Internet control has incurred an up to 25% reduction in research quality for Chinese scholars conditional on the knowledge-intensity of their discipline. This occurred specifically via a reduction in the access to cutting-edge knowledge from the outside world. These findings suggest that while politically motivated information flow restrictions do take a toll on the country’s long-term capacity for innovation, they lend a short-term benefit to its data-intensive sectors. Conventional wisdom on the inherent limit to information control by autocracies overlooks this crucial protectionist benefit that aids in autocratic power consolidation in the digital age. 

This session is part of the Fall Seminar Series, a months-long series designed to bring researchers, policy makers, scholars and industry professionals together to share research, findings and trends in the cyber policy space. Both in-person and virtual attendance is available; registration is required.

joan donovan and emily dreyfuss headshots with book cover Meme wars

Join the Program on Democracy and the Internet (PDI) and moderator Nate Persily, in conversation with Dr. Joan Donovan, Research Director of the Shorenstein Center on Media, Politics and Public Policy, and Emily Dreyfuss, a journalist who covers the impact of technology on society, with a focus on social media and information systems.

Memes have long been dismissed as inside jokes with no political importance. Nothing could be further from the truth. Memes are bedrock to the strategy of conspiracists such as Alex Jones, provocateurs like Milo Yiannopoulos, white nationalists like Nick Fuentes, and tacticians like Roger Stone. While the media and most politicians struggle to harness the organizing power of the internet, the “redpill right” weaponizes memes, pushing conspiracy theories and disinformation into the mainstream to drag people down the rabbit hole. These meme wars stir strong emotions, deepen partisanship, and get people off their keyboards and into the streets--and the steps of the US Capitol.  Meme Wars is the first major account of how “Stop the Steal” went from online to real life, from the wires to the weeds. Leading media expert Joan Donovan, PhD, veteran tech journalist Emily Dreyfuss, and cultural ethnographer Brian Friedberg pull back the curtain on the digital war rooms in which a vast collection of antiesablishmentarians bond over hatred of liberal government and media. Together as a motley reactionary army, they use memes and social media to seek out new recruits, spread ideologies, and remake America according to their desires.

This session is part of the Fall Seminar Series, a months-long series designed to bring researchers, policy makers, scholars and industry professionals together to share research, findings and trends in the cyber policy space. Both in-person and virtual attendance is available; registration is required.

Dr. Joan Donovan is the Research Director of the Shorenstein Center on Media, Politics and Public Policy. Dr. Donovan leads the field in examining internet and technology studies, online extremism, media manipulation, and disinformation campaigns.

Dr. Donovan leads The Technology and Social Change Project (TaSC). TaSC explores how media manipulation is a means to control public conversation, derail democracy, and disrupt society. TaSC conducts research, develops methods, and facilitates workshops for journalists, policy makers, technologists, and civil society organizations on how to detect, document, and debunk media manipulation campaigns.

Emily Dreyfuss is a journalist who covers the impact of technology on society, with a focus on social media and information systems. She is the senior editor of the Technology and Social Change (TaSC) team and the co-lead of the Harvard Shorenstein Center News Leaders summit. Emily got her start in journalism as a local newspaper reporter, then as an editor at an alt-weekly, before entering the tech reporting fray as an editor at CNET. She was a senior writer and editor at WIRED for many years and most recently helped launch the tech news site Protocol. As a 2017-2018 Harvard Nieman Berkman Klein fellow, Emily studied ephemerality and the internet. She is interested in how technology accelerates change.

joshua tucker headshot for echo chambers, rabbit holes and algorithmic bias seminar

Join the Program on Democracy and the Internet (PDI) and moderator Nate Persily, for the next seminar in the Fall Seminar SeriesEcho Chambers, Rabbit Holes, and Algorithmic Bias: How YouTube Recommends Content to Real Users with Joshua Tucker, Professor of Politics, Director of the Jordan Center for the Advanced Study of Russia, Co-Director of New York University's Center for Social Media and Politics(CSMaP), Affiliated Professor of Russian and Slavic Studies, and Affiliated Professor of Data Science.

To what extent does the YouTube recommendation algorithm push users into echo chambers, ideologically biased content, or rabbit holes? Despite growing popular concern, recent work suggests that the recommendation algorithm is not pushing users into these echo chambers. However, existing research relies heavily on the use of anonymous data collection that does not account for the personalized nature of the recommendation algorithm. We asked a sample of real users to install a browser extension that downloaded the list of videos they were recommended. We instructed these users to start on an assigned video and then click through 20 sets of recommendations, capturing what they were being shown in real time as they used the platform logged into their real accounts. Using a novel method to estimate the ideology of a YouTube video, we demonstrate that the YouTube recommendation algorithm does, in fact, push real users into mild ideological echo chambers where, by the end of the data collection task, liberals and conservatives received different distributions of recommendations from each other, though this difference is small. While we find evidence that this difference increases the longer the user followed the recommendation algorithm, we do not find evidence that many go down `rabbit holes' that lead them to ideologically extreme content. Finally, we find that YouTube pushes all users, regardless of ideology, towards moderately conservative and an increasingly narrow range of ideological content the longer they follow YouTube's recommendations.

This session is part of the Fall Seminar Series, a months-long series from the Program on Democracy and the Internet, designed to bring researchers, policy makers, scholars and industry professionals together to share research, findings and trends in the cyber policy space. Both in-person and virtual attendance is available; registration is required. Lunch will be provided for in-person attendees.

tim hwang headshot with text microeconomics of disinformation over the top

Join the Program on Democracy and the Internet (PDI) and moderator Nate Persily, in conversation with Tim Hwang, General Counsel of Substack, for a look at how microeconomics and disinformation are connected. Despite the tendency to wildly speculate on the future of disinformation and next-generation psychological operations, the vast majority of propagandists are rank pragmatists. How might microeconomic principles help us understand how disinformation campaigns are actually organized, and the kinds of tactics they are likely to deploy going into the future? This session will explore some early research exploring the small but critical incentives that shape tactical decisionmaking around disinformation efforts, and how such a framework might be used to ground threat modeling going forwards. 

This session is part of the Fall Seminar Series, a months-long series designed to bring researchers, policy makers, scholars and industry professionals together to share research, findings and trends in the cyber policy space. Both in-person and virutal attendance is available; registration is required.

About the Speaker:

Tim Hwang is a writer and researcher, currently the general counsel at Substack. He’s the author of Subprime Attention Crisis, a book about the online advertising bubble. He’s a research fellow at the Center for Security and Emerging Technology, is on the board of Meedan, and is an investor in Temescal Brewing.

Co-sponsored by Peking University and the Asia Health Policy Program

Time cost of healthcare is important but is largely overlooked in the literature. This paper investigates how time cost affects the healthcare usage in both China and the US. Using the retirement age policy in both countries, we first employ a Regression Discontinuity Design (RDD) and show that the hospitalization rate persistently increases by 20-30 percent just after retirement age. The effects are larger and more significant among the people with higher time costs prior to retirement. Then, we use the school starting date and provide further significant evidence of the impact of time cost on hospitalization among the age-eligible children. These results underline the remarkable impact of time cost on healthcare usage and provide a more comprehensive picture of moral hazard in health insurance.

Negative Behavioral Transmission

Behavior change programs, including much of early education curricula, assume the positive transmission of behavior from one context to another. We randomize a hand hygiene edutain- ment program in schools in Bangladesh to trace school-to-home transmission of handwashing behavior and randomize the proportion of students who receive handwashing resources at home to track home-to-school transmission. We find that children induced to wash more at home exhibit less washing at school. Likewise, children induced to wash more at school wash less at home. This negative transmission spills over to other household members and non-school days, such that the cumulative impact of school edutainment on total washing is negative. Our results are consistent with the mechanisms of crowd-out, cue-based habit formation, and ‘reverse’ vertical transmission of behavior. They highlight an unintended consequence of behavior change interventions, like those often implemented in education, that presume complementarities in behavior across contexts but evaluate effects only at the site of intervening. 

Reshma Hussam, PhD, is an assistant professor of business administration in the Business, Government and International Economy Unit at Harvard Business School, a Faculty Research Fellow at the National Bureau of Economic Research (NBER), and a faculty affiliate at the Abdul Latif Jameel Poverty Action Lab (J-PAL) and the Bureau for Research and Economic Analysis of Development (BREAD).

Her research explores questions at the intersection of development and behavioral economics, with research in three areas: migration, health, and finance.  Her most recent work engages refugee populations including the Rohingya in Bangladesh, examining the psychosocial value of employment in contexts of mass unemployment, the role of home in migration decisionmaking, and refugee preferences for repatriation, integration, and resettlement. In her work in health, which involves field experiments across South Asia, she considers the puzzle of the ubiquitously low adoption of low cost, high return goods, behaviors, and technologies in the developing world, exploring the role of learning and habit formation in behavior change.
