NCA analysis of the economic effects of a pandemic
NCA working paper on economic recovery after a pandemic
A working paper was published in which NCA is applied to recent data from the 1918 influenza pandemic ('Spanish Flu') to study the effects of social distancing policies on recovery of the economy after the pandemic.
Pandemics harm the economy. Governments use social distancing and other non-pharmaceutical interventions (NPI) to tackle the pandemic. Recent data from the 1918 influenza pandemic ('Spanish Flu') suggest that a strict NPI policy on average not only reduces mortality but is also helpful to recover the economy after the pandemic. Using Necessary Condition Analysis (NCA) we show that a strict policy is necessary for high economic performance. Specifically, we find that for high economic performance NPI policies must be implemented rapidly and must be intense, otherwise they fail to recover the economy. The potential lessons for the COVID-19 pandemic are discussed. The results also provide a reflection on the current societal call for quickly abandoning the imposed strict social distancing measures.
