Last January, the John Hopkins Institute for Applied Economics, Global Health and the Study of Business Enterprise published a working paper which showed clearly how lockdowns across the world did not affect Covid-19 mortality at all.
The paper, is written by economists Jonas Herby, Lars Jonung and Steve H. Hanke, now appearing in its final version, titled A LITERATURE REVIEW AND META-ANALYSIS OF THE EFFECTS OF LOCKDOWNS ONCOVID-19 MORTALITY - II. The use of lockdowns is a unique feature of the COVID-19 pandemic.
Lockdowns have not been used to such a large extent during any of the pandemics of the past century.
Lockdowns during the initial phase of the COVID-19 pandemic have had devastating effects.
These costs to society must be compared to the benefits of lockdowns, which our meta-analysis has shown are little to none.
Such a standard benefit-cost calculation leads to a strong conclusion: until future research based on credible empirical evidence can prove that lockdowns have large and significant reductions in mortality, lockdowns should be rejected out of hand as a pandemic policy instrument.
Appendix II is a particularly interesting read. Some readers may recall the media storm against this paper, driven by some self-proclaimed fact-checkers.
