Time-varying Cost of Distancing: Distancing Fatigue, Holidays and Lockdowns

  title={Time-varying Cost of Distancing: Distancing Fatigue, Holidays and Lockdowns},
  author={Christoph Carnehl and Satoshi Fukuda and Nenad Kos},
We study an SIR model with endogenous behavior and a time-varying cost of distancing. We show that a steep increase in distancing cost is necessary for a second wave of an epidemic to arise. As a special case of the model with changing cost, we study distancing fatigue—the distancing cost increases in past distancing—and show that it cannot generate a second wave. Moreover, we characterize the change in the distancing cost necessary for the slope of prevalence to change its sign. This…

Epidemics with behavior

Lockdown fatigue: The diminishing effects of quarantines on the spread of COVID-19

Non-Pharmaceutical Interventions (NPIs) have been for most countries the key policy instrument utilized to contain the impact of the COVID-19 pandemic. In this article, we conduct an empirical

Equilibrium Social Distancing

This paper presents an economic model of an epidemic in which susceptible individuals may engage in costly social distancing in order to avoid becoming infected. Infected individuals eventually

Internal and external effects of social distancing in a pandemic

We develop a quantitative framework for exploring how individuals trade off the utility benefit of social activity against the internal and external health risks that come with

Optimal Control of an Epidemic through Social Distancing

We analyze how to optimally engage in social distancing (SD) in order to minimize the spread of an infectious disease. We identify conditions under which the optimal policy is single-peaked, i.e.,

Impacts of State Reopening Policy on Human Mobility

This study quantifies the effect of state reopening policies on daily mobility, travel, and mixing behavior during the COVID-19 pandemic. We harness cell device signal data to examine the effects of

Maximize Utility Subject to R≤1: A Simple Price-Theory Approach to Covid-19 Lockdown and Reopening Policy

The formulation provides economics language for a policy middle ground between society-wide lockdown and ignore-the-virus, and a new infectious threat response paradigm alongside “eradicate” and “minimize”.

A Simple Model of Social Distancing and Vaccination

This paper analyzes a simple model of infectious disease where the incentives for individuals to reduce risks through endogenous social distancing take straightforward cost-benefit form. Since

Game Theory of Social Distancing in Response to an Epidemic

A differential-game is formulates to identify how individuals would best use social distancing and related self-protective behaviors during an epidemic and shows how the window of opportunity for vaccine development lengthens as the efficiency of social distanced and detection improve.

A Simple Planning Problem for COVID-19 Lock-down, Testing, and Tracing

We study the optimal lock-down for a planner who controls the fatalities of COVID-19 while minimizing the output costs of the lockdown. The policy prescribes a severe lock-down beginning a few weeks
