READ THE PAPER

  • Rich and poor countries enacted similar lockdowns, despite different disease risks.
  • We build a hybrid macroeconomic and epidemiological model to explain these choices.
  • Calibrations match actual economic and health gaps between rich and poor countries.
  • Demography alone predicts laxer policies in poorer countries.
  • But, counterintuitively, basic subsistence needs may explain stricter policies.


Abstract: The COVID-19 pandemic led governments around the world to impose unprecedented restrictions on economic activity. Were these restrictions equally justified in poorer countries with fewer demographic risk factors and less ability to weather economic shocks? We develop and estimate a fully specified model of the macroeconomy with epidemiological dynamics, incorporating subsistence constraints in consumption and allowing preferences over “lives versus livelihoods” to vary with income. Poorer countries’ demography pushes them unambiguously toward laxer policies. But because both infected and susceptible agents near the subsistence constraint will remain economically active in the face of infection risk and even to some extent under government containment policies, optimal policy in poorer countries pushes in the opposite direction. Moreover, for reasonable income-elasticities of the value of a statistical life, the model can fully rationalize equally strict or stricter policies in poorer countries.
