About the talk

The COVID-19 pandemic revealed significant gaps in global preparedness. As we navigate the recovery phase, the risk of future pandemics remains one of the most pressing challenges to global safety. During the pandemic, a wide range of control measures were implemented worldwide, often with limited evidence of their effectiveness. In the project “Lessons from pandemic”, we investigate the effectiveness and impact of these measures—the key strategies employed by governments in response to the pandemic—from multiple perspectives through a comprehensive analysis of various sources of COVID-19 data from different regions in Norway. Our objective is to identify optimal strategies that mitigate health risks and minimize unnecessary social and economic burdens. Ultimately, we aim to transform the insights gained from the COVID-19 experience into actionable strategies that strengthen preparedness for future health crises. In my talk, I will present preliminary findings from this ongoing project.

Blurb: Millions of people have lost a relative to COVID-19, with many of these individuals likely to be alive well into this century. How might this population influence how the COVID-19 pandemic is remembered, and how may this shape policy and popular responses to future crises? This talk presents ongoing research using demographic microsimulation to predict the extent and trajectory of what we term “kinship memory” – the share of a population bereaved by a mortality crisis – in the context of COVID-19 in 120 countries around the world from 2025 to 2100. Our findings show that the continued survival of a large proportion of grandchildren will contribute to greater stability of kinship memory, with around 1 percent of the 2100 population of most regions related to a victim. However, the extent of this stability is limited by the relatively older age structure of COVID-19 excess mortality, which shapes the predicted ages of bereaved kin and the extent of their projected survival. Our work highlights the role of demographic structure of both the group of bereaved relatives and the overall population in shaping the projected kinship memory of a crisis.

Bio: Mallika Snyder is a Research Scientist at the Max Planck Institute for Demographic Research (MPIDR) in the Department of Digital and Computational Demography. Her research focuses on measuring the demographic impact of crisis-related population change in limited-data settings, and better understanding its implications for affected populations and individuals. Drawing on computational demographic methods and non-traditional data sources, her recent work has explored topics including the effects of COVID-19 excess mortality on kinship networks, as well as the development of innovative methods to better integrate information on crisis-related mobility into subnational population projections used to inform United Nations humanitarian action. A graduate of the UC Berkeley PhD program in Demography and the MA in Statistics, she recently joined MPIDR from the United Nations Population Fund (UNFPA), where she worked as an applied demographer focused on population data and estimation in humanitarian settings.

Blurb: How do societies use institutions – the humanly devised rules of social interaction – to tackle epidemic disease? Controlling Contagion (Princeton University Press, 2025) uses evidence from seven centuries of pandemics to show how societies tackled externalities – situations where my action creates costs or benefits for others in addition to those that I myself incur. It explores how markets, states, communities, religions, guilds, and families dealt with the negative externalities of contagion; the positive externalities of social distancing, sanitation, and immunisation; and the cross-border externalities of quarantine, vaccine diplomacy, and river agreements. It shows how, long before scientific medicine, human societies coordinated and innovated to deal with biological shocks.

Biography: Sheilagh Ogilvie is the Chichele Professor of Economic History at the University of Oxford and a Fellow of the British Academy. She explores the lives of ordinary people in the past and tries to explain how poor economies get richer and improve human well-being.

Blurb: The 1957-58 Asian flu was one of the global pandemics caused by the influenza ‘A’ virus, subtype H2N2. This flu pandemic claimed approximately one to four million lives, making it one of the deadliest pandemics in history. Generally, published research literature on Asian flu is scarce. A few studies document its history in Europe, the Americas, and Asia. Limited information exists regarding the history and socioeconomic consequences of the pandemic in Africa. This paper aims to fill this lacuna by exploring the history of the pandemic in colonial Tanganyika. It demonstrates that, although the virus primarily affected Asia, Europe, and North America, Africa was also impacted, indicating that the continent was equally vulnerable to global pandemics. Tanganyika, for instance, was among the first African colonial territories severely affected by the virus, experiencing its impact at an early stage. This paper critically examines the responses of the colonial government, the World Health Organization, and the community in their efforts to combat influenza, highlighting the urgency of the situation. Overall, the paper illuminates that the flu infected many individuals and sparked significant panic in both the colonial public health sector and the general community. However, compared to the 1918-19 Spanish flu, the Asian flu recorded lower morbidity and mortality rates due to its nature and the effective use of antibiotics and other non-biomedical measures. Focusing on Tanganyika, this paper employs a qualitative analytical method on relevant archival and published sources to uncover the history of the pandemic in colonial Africa.

Blurb: Tuberculosis as a chronic infectious disease seems to sit oddly with common notions of what is to be considered epidemic or endemic. As a result, the conditions presence is often endemic in character, but the term itself is rarely employed. However, the question of an epidemic or endemic character was explicitly addressed was in studies of African tuberculosis between the world wars. Around 1930, researchers were exploring its presence in Africa, and many were favouring Lyle Cummins’ hypothesis that, much like European colonisation, the condition was a recent arrival in Africa. This meant that there had to be a quickly spreading epidemic into a susceptible population. In my paper, I will look at the epidemiological surveying that was done in Northern Tanganyika in exploration of Cummins’ theory. What does it teach us about colonial science? What happened to Cummins’ explanation when available data – as they were – supported it less and less?

Blurb: Why were some regions hit much harder by COVID-19 than others—and how new was this geography of mortality? In this talk, I will examine regional excess mortality during the pandemic in 2020 and 2021 across more than 500 regions in France and Europe, highlighting which areas were most affected and how spatial patterns evolved over time. I will then compare these recent patterns with four major mortality crises of the 20th and 21st centuries: the Spanish flu, the 1911 and 2003 heatwaves, and the Hong Kong flu. Using harmonized regional mortality data from the French Human Mortality Database, I will explore how the magnitude and spatial structure of excess mortality during COVID-19 fit within a longer historical continuum of longevity shocks.

Biography: Florian Bonnet is a tenured researcher at the French Institute for Demographic Studies (Ined). His work lies at the intersection of demography, economics, history, and geography, with a focus on the long-term evolution of social and spatial inequalities in longevity and economic development in France and across Europe. He combines historical data reconstruction with spatial and statistical analysis to uncover how regional disparities in mortality and living standards have emerged, persisted, and transformed over time.

Blurb: A large body of social science and health research uses measures of the 1918 influenza pandemic’s mortality to estimate what the biosocial effects of the pandemic were. However, many of the pandemic measures used in this research either exhibit very high rates of error; are systematically correlated with pre-pandemics determinants of the effect of interest; or are a poorly chosen estimand for testing the causal chain of interest. Additionally, even though pandemics have wide-ranging impacts on society, many existing studies do not attempt to rule out plausible alternate channels linking the pandemic to the effect of interest. Each of these four methodological problems can produce false negative results, false positive results, and false positive results of the incorrect sign. We illustrate the extent of these problems using a series of helpful case studies from the 1918 context. In doing so, we make methodological contributions that stress the importance for causal research on pandemic of conducting sensitivity analyses on the calculation of excess mortality, accounting for omitted variable and collider bias, and measuring pandemic severity for the most theoretically appropriate time period and point-of-view.

Biography: Hampton Gaddy is a PhD researcher in demography and economic history at the London School of Economics and an affiliate at the Leverhulme Centre for Demographic Science at the University of Oxford. He works primarily on the 1918 influenza pandemic, the determinants of its mortality, and its social consequences.

For the second Pandemics & Society Seminar of our Fall 2025 series we are pleased to welcome Max Marczinek (University of Oxford). The seminar will be held on Thursday, 25 September at the normal time (1600 CEST). More information about our speaker and the presentation is below.

Blurb: In this webinar, Marczinek will present a paper studying the relationship between labour scarcity and productivity in the context of a 1710s plague outbreak. While higher wages should have led to an export contraction, exports grew after plagued regions shifted into capital-intensive production. Using a Ricardian model, he show that productivity growth in capital-intensive sectors is best suited to explain this export boom. Marczinek argue that labour scarcity incentivises capital-intensive production which raises productivity growth.

Biography: Max Marczinek is a 4th year PhD student in Economics at Oxford University. His research studies trade, labour, and economic history. He combine trade models with novel and often historical data sources, using theory to extract new insights from granular data.
