Excerpts from the December 2020 paper by the new UK Health Secretary https://www.hks.harvard.edu/sites/default/files/centers/mrcbg/programs/senior.fellows/20-21/Sajid%20Javid.pdf
● Better preparation for HILPs include greater respect and fear for uncertainty and non-linear
risks, the building political institutions better able to cope with mounting, random events, in
particular thought “circuit breakers, fail-safe protocols, and backup systems,” to protect from
catastrophic losses like with COVID. And ideal crisis management style is (i) nimble: Move quickly in
exponential growing problems, (ii) adaptive, i.e., regularly updating priors and action based on new
information, (iii) wise: incorporate best scientific knowledge, (iv) humble: embracing uncertainty, (v)
long-term: not just based on the political cycle, and (vi) effective communication.
● COVID’s conditions favour “herd behavior” among policy makers, but it is hard to
prove. Herd Behavior, sometimes known as “information cascades”, is defined as “everyone doing
what everyone else is doing, even when their private information suggests doing something quite
different” (Banerjee, 1992). This type of behavior is empirically common (from investor behavior in
the stock market to new technology adoption) and can be beneficial or sub-optimal in models
depending on context and information availability. Now, many factors that took place during COVID
provided heightened conditions for herd behavior, such as empirical evidence that crisis, fear,
volatility and uncertainty all increase the likelihood of herd behavior, or the interaction between
global leaders’ identity grouping and decision making, as the fact that other types of herd behavior
were observed in most populations (e.g., hoarding of toilet paper) and the market (massive volatility).
If indeed herd-behavior took place, it would be important to consider how this behavior can
negatively impact equilibria: for example, giving “first movers” out-sized influence in a final
equilibrium (anchoring). However, proving herding necessitates availability of private information,
i.e., some leader who took action against his/her own best judgment, which is hard to do.
