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.

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

The Italian Society of Economists (SIE) invites to a webinar with Eleni Lioliou (Queen Mary University of London School of Business and Management) and Giovanni Cerulli (IRCrES-CNR - Research Institute on Sustainable Economic Growth) on Thursday, June 25 at 5 PM CEST.

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.

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.

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.

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.

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.

You are invited to a CEPR / LSE IGA / SPP webinar, co-organised with SITE at Stockholm School of Economics, hosting a panel discussion with Karolina Ekholm, Jeremy Farrar, Bengt Holmström, Devi Sridhar and Erik Berglöf.

The Stockholm School of Economics launched today the first part of the new report "Sweden through the crisis". In it you can read views and perspectives from researchers connected to the School.
