This paper examines two key aspects of unemployment-its propagation mechanism and socioeconomic costs. It identifies a key feature of this macroeconomic phenomenon: it behaves like a disease. A detailed assessment of the transmission mechanism and the existing pecuniary and nonpecuniary costs of...

We embed a lockdown choice in a simplified epidemiological model and derive formulas for the optimal lockdown intensity and duration. The optimal policy re- ects the rate of time preference, epidemiological factors, the hazard rate of vaccine discovery, learning effects in the health care...

We propose a exible model of infectious dynamics with a single endogenous state variable and economic choices. We characterize equilibrium, optimal outcomes, static and dynamic externalities, and prove the following: (i) A lockdown generically is followed by policies to stimulate activity. (ii)...

This paper examines the impact of the SARS epidemic in 2003 on intergenerational mobility in China. Using large cross-city variation in SARS cases, our triple difference-in-differences estimates suggest that the SARS epidemic significantly increases the intergenerational transmission of...

We embed a lockdown choice in a simplified epidemiological model and derive formulas for the optimal lockdown intensity and duration. The optimal policy reflects the rate of time preference, epidemiological factors, the hazard rate of vaccine discovery, learning effects in the health care...

We propose a exible model of infectious dynamics with a single endogenous state variable and economic choices. We characterize equilibrium, optimal outcomes, static and dynamic externalities, and prove the following: (i) A lockdown generically is followed by policies to stimulate activity. (ii)...

We develop a flexible single-state model to represent tradeoffs between infections and activity during the early phase of an epidemic. We prove that optimal policy is continuous in the state but discontinuous in the deterministic arrival date of a cure; optimal lockdowns are followed by stimulus...

Vaccinations, lockdowns and testing strategies are three potential elements of an effective anti-coronavirus, and in particular Covid-19, health policy. The following analysis considers - within a simple model - the potentially crucial role of a Corona testing approach in combination with a...

Vaccination represents a canonical example of externalities in economics, yet there are few estimates of their magnitudes. I estimate social and externality benefits of influenza vaccination in two settings. First, using a natural experiment, I estimate the impacts of aggregate vaccination rates...

We analyze the effects of a vaccination program providing free flu vaccine to individuals aged 65 or more on take-up and hospitalization. By using linked patient-general practitioner (GP) data, we implement a regression discontinuity design around the threshold at age 65. We find that the...
