Ironically (per the quote below), just after posting an excerpt from my weekend notes (where I questioned the prospects for a V-shaped recovery) I read a recent study titled “Longer-Run Economic Consequences of Pandemics” by economists Oscar Jorda, Sanjay Singh and Alan Taylor.

Here are their conclusions:  emphasis mine…

“Summing up our findings, the great historical pandemics of the last millennium have typically been associated with subsequent low returns to assets, as far as the limited data allow us to conclude. These responses are huge. Smaller responses are found in real wages, but still statistically significant, and consistent with the baseline neoclassical model.

Measured by deviations in a benchmark economic statistic, the real natural rate of interest, these responses indicate that pandemics are followed by sustained periods—over multiple decades—with depressed investment opportunities, possibly due to excess capital per unit of surviving labor, and/or heightened desires to save, possibly due to an increase in precautionary saving or a rebuilding of depleted wealth.

Either way, if the trends play out similarly in the wake of COVID-19—adjusted to the scale of this pandemic—the global economic trajectory will be very different than was expected only a few weeks ago. If low real interest rates are sustained for decades they will provide welcome fiscal space for governments to mitigate the consequences of the pandemic. The major caveat is that past pandemics occurred at time when virtually no members of society survived to old age. The Black Death and other plagues hit populations with the great mass of the age pyramid below 60, so this time may be different.”

The abstract:

“How do major pandemics affect economic activity in the medium to longer term? Is it consistent with what economic theory prescribes? Since these are rare events, historical evidence over many centuries is required. We study rates of return on assets using a dataset stretching back to the 14th century, focusing on 12 major pandemics where more than 100,000 people died. In addition, we include major armed conflicts resulting in a similarly large death toll. Significant macroeconomic after-effects of the pandemics persist for about 40 years, with real rates of return substantially depressed. In contrast, we find that wars have no such effect, indeed the opposite. This is consistent with the destruction of capital that happens in wars, but not in pandemics. Using more sparse data, we find real wages somewhat elevated following pandemics. The findings are consistent with pandemics inducing labor scarcity and/or a shift to greater precautionary savings.”
