Age Specificity of Infection Fatality Rates for COVID-19

05 August 2020
The overall Covid19 Infection Fatality Rate (IFR) for a given location is intrinsically linked to the age-specific pattern of infections.

Effect of Covid-19 on global productivity

21 July 2020
The World Bank has published a new book on “Global Productivity: Trends, Drivers, and Policies”, edited by Alistair Dieppe, with a database covering 164 countries over 1980-2018. The book analyses the long-run trend in global productivity but covers also the potential effects of Covid-19.

The macroeconomics of age-varying epidemics

21 July 2020
A new working paper from Marta Giagheddu and Andrea Papetti illustrates the pros and cons of different combinations of economic shutdown and targeted social distancing with a special focus on the dimension of intergenerational contacts.

Influence of population heterogeneity on herd immunity to SARS-CoV-2

01 July 2020
MIT economist Glenn Ellison surveys the epidemiological literature on an SIR extension incorporating heterogeneity in the activity rates of different subpopulations, and notes ways in which analyses based on classic SIR models can potentially yield misleading views. In a similar spirit, a new study by mathematics professor Tom Britton shows that population heterogeneity can significantly impact disease-induced immunity.

Optimal dynamic confinement under uncertainty and learning

01 July 2020
In a new paper, network member Christian Gollier analyzes the uncertainty surrounding how contagious a virus is and how that affects optimal suppression.

Waning Immunity and the Second Wave: Some Projections for SARS-CoV-2

22 June 2020
Network member Flavio Toxvaerd with coauthors consider, in a new working paper, the optimal social distancing policy in an SEIRS model of the COVID-19 epidemic in which immunity wanes over time.

Nowcasting COVID-19 statistics

22 June 2020
Statistics are often registered with delay and Swedish COVID-19 deaths are reported with up to 14 days of lag. Death statistics therefore always appear to be on a positive trend. In a new paper, SSE-CERN member Adam Altmejd together with Joacim Rocklöv, and Jonas Wallin propose a statistical method to estimate the actual number of deaths.

Predicted fatality rates for Covid-19 around the world

18 June 2020
Early reports suggest the fatality rate from COVID-19 varies greatly across countries, but non-random testing and incomplete vital registration systems render it impossible to directly estimate the infection fatality rate (IFR) in many low- and middle-income countries. A new study tries to fill this gap.

What policies address both the coronavirus crisis and the climate crisis?

17 June 2020
In a new paper, network members Niko Jaakkola and Daniel Spiro with co-authors analyse policies that would jointly address the coronavirus economic crisis and the climate crisis.

Face Masks Considerably Reduce COVID-19 Cases in Germany

16 June 2020
The effect of face masks worn in public on the spread of Covid-19 has not been systematically analyzed so far. A new IZA Discussion Paper by Klaus Wälde and coauthors uses the synthetic control method to analyze the effect of face masks on the spread of Covid-19 in Germany.
