  "summary": "The large economic costs of full-blown lockdowns in response to COVID-19 outbreaks, coupled with heterogeneous mortality rates across age groups, led to question non-discriminatory containment measures. In this paper we provide an assessment of the targeted approach to containment.",

      "content": "- The paper assesses targeted containment as an alternative to non-discriminatory (blanket) lockdowns in response to COVID-19 outbreaks.\n- It develops a SIR-macro model with heterogeneous agents by mortality rates and contact rates, where the government optimally bans people from working.\n- Core tradeoff: targeted containment reduces deaths relative to blanket policies but leads to a larger and longer recession because containment applies to a larger fraction of people, is held for longer, and delays herd immunity.\n- Increased interactions between low- and high-risk individuals reduce the effectiveness of targeted containment."

      "heading": "Main Findings",
      "content": "- Under a targeted policy, the optimal containment:\n  - Reaches a larger portion of the population than under a blanket policy.\n  - Is held in place for longer than under a blanket policy.\n- Health outcome:\n  - A targeted approach results in a smaller death count compared to a blanket policy.\n- Economic outcome:\n  - The recession is larger under a targeted approach than under a blanket policy.\n  - Reasons: containment applies to a larger fraction of people, remains in place longer, and herd immunity is achieved later.\n- Interaction effects:\n  - Increased interactions between low- and high-risk individuals effectively reduce the benefits of a targeted approach."

      "heading": "Policy Implications",
      "content": "- Targeted containment can reduce mortality but at the cost of deeper and more prolonged economic contraction.\n- Policymakers should consider the degree of interaction between risk groups when evaluating targeted containment, as high interaction undermines benefits.\n- Optimal policy design must balance mortality reduction against larger recessionary effects and delayed herd immunity.\n\n---\n\n Content in this bundle\n\n- Working Paper\n  - Working Paper (Markdown version){rel=\"alternate\" type=\"text/markdown\"}\n  - Working Paper (PDF){rel=\"external\" type=\"application/pdf\"}\n\n---\n\nSource: https://www.imf.org/en/publications/wp/issues/2020/12/11/assessing-targeted-containment-policies-to-fight-covid-19-49878"
