报告摘要:The Covid-19 pandemic has put in the forefront the need to balance the health benefits and the economic costs when it comes to imposing constraints on business activity. The goal is to find the optimal balance over the life of the pandemic, and avoid myopic reactions. A tricky aspect of the problem is that opening up business has an immediate positive effect in the economic metrics, but a delayed and lingering negative effect on the health costs. In addition, a non-trivial formulation needs to account for improvements over time in the prevention and treatment of the disease, and that the spread of the disease has direct effects on business over and above health costs. We tackle this challenge through formulating a continuous objective function where the decision variable (economic activity allows at each point in time) has both an instant effect on business output (flow component) and a delayed effect on health (by increasing the stock of severally ill individuals). We are the first to study an optimization problem that contains both a flow and a reservoir component satisfying the local substitution property, and obtain structural and closed-form solutions of the optimal control policy for both finite horizon (the pandemic ends when a vaccine arrives) and infinite horizons (no vaccine).
