This paper investigates the role of testing and age-composition in the Covid-19 epidemic. We augment a standard SIR … cold. Testing reduces the time of uncertainty. Individuals are heterogeneous with respect to age. Younger people are less … policy responses in terms of testing, confinements, and selective mixing by age group. …

Countries worldwide have implemented lockdown measures to contain the covid-19 pandemic. After more than three months … while keeping the epidemic in check. Here I use basic economic principles to shed light on the key tradeoffs. A central … message is that there is no "health vs. economics" dichotomy. Rather, some degree of lockdown is typically optimal in crisis …

We embed a lockdown choice in a simplified epidemiological model and derive formulas for the optimal lockdown intensity … discovery, learning effects in the health care sector, and the severity of output losses due to a lockdown. In our baseline …

alternative evolution of the pandemic, assuming that states extended the lockdown measures until daily new cases reach the levels … of European countries after their lockdown measures were relaxed. In the baseline simulation, we find that cases and …

We show that LP chains reacted the most to the lockdown with spatial heterogeneity. The …

This paper reexamines the design of the optimal lockdown strategy by paying attention to its robustness to the … postulated social welfare criterion. We first characterize optimal lockdown under utilitarianism, and we show that this social …-maximal lockdown saving lives at the cost of reducing average utility at a given period, there exists always a stricter lockdown, which …
