In times of crisis, such as a pandemic, markets may not work well for products or services under urgent demand, say for exmaple virus tests. Mechanism design, proposes Eric Maskin, can be enlisted to help.
Drawing on models developed by network scientists, Gianluca Manzo and Arnout van de Rijt suggest that targeted testing of highly connected individuals can dramatically improve containment in a population coming out of lockdown and help preventing a second wave. Concrete procedures could be acquaintance sampling and employment-based targeting.
Public-health authorities from around the world have to make decisions about many individuals under uncertainty over their Covid-19 infection statuses with limited test portfolios of heterogeneous qualities. Jeffrey Ely, Andrea Galeotti and Jakub Steiner develop an algorithmic solution for the test-allocation problem.
Krishna Dasaratha studies how behavioral responses impact on the spread of a contagious disease like Covid-19. The results challenge some of the conventional wisdom such as that infection rates stop growing due to behavioral responses in combination with herd immunity.
Carlos Garriga, Rody Manuelli and Siddhartha Sanghi study a dynamic macro model to capture the trade-off between policies that simultaneously decrease output and the rate of infection transmission. Findings suggest that, in many cases, optimal policies require sharp initial decreases in employment followed by a partial liberalization that occurs before the peak of the epidemic. The study also discusses the impact of the arrival of a vaccine and its changing value as the epidemic progresses.
This paper presents a new data set collected on representative samples across 6 countries: China, South Korea, Japan, Italy, the UK and the four largest states in the US. The information collected relates to work and living situations, income, behavior (such as social-distancing, hand-washing and wearing a face mask), beliefs about the Covid 19 pandemic and exposure to the virus, socio-demographic characteristics and pre-pandemic health characteristics. (The data can be accessed here.)

Studying the macroeconomic impact of lockdown measures, Neha Bairoliya and Ayse Imrohoroglu find that mitigation efforts targeted towards certain age and health groups result in significantly smaller economic disruptions compared to an indiscriminate lockdown.
Combining epidemiology with economic models, Simon Loertscher and Ellen V. Muir determine the minimum degree of lockdown that assures that the maximum capacity of the health care system is not exceeded while a certain amount of social and economic liberty is preserved.
On this important topic, Nikolaj Broberg points us to a paper that examines the news coverage of the Corona pandemic in the two US cable news shows Hannity and Tucker Carlson Tonight (Fox).
