Optimal lockdowns under constraints
系统研究了摩擦对最优疫情应对的影响，特别是检测交付和封锁效果的约束，揭示了封锁与检测之间复杂且有时反直觉的关系，并发现封锁政策对其效率变化具有显著稳健性。
Abstract We present a systematic examination of the impact of frictions on optimal pandemic response, bridging the significant gap between policy recommendations and implementation. We focus in particular on constraints in testing delivery and in lockdown efficacy in the context of a canonical pandemic model. The latter is modified for a more faithful representation of lockdowns. The paper sheds light on nuanced, and sometimes counter‐intuitive, relationships. It rationalizes key but divergent findings in the literature on the extent of substitution and complementarity between lockdowns and testing. It also demonstrates remarkable robustness in lockdown policy to changes in its efficiency.
