Sharp post.

When officials misbehave, we naturally wonder: How much is due to incompetence? And how much to malice? In Arnold's terms, we may wonder: How much is due to the knowledge problem? And how much to selection and corruption?

In the case of the pandemic, I would lean more than Arnold to selection and corruption.

For example, Arnold writes: "Consider policy during the pandemic. In principle, regulators should have carefully calculated the trade-offs involved in closing schools and restricting people’s activities. In practice, they lacked the means to do so."

School closures persisted *much* longer than any knowledge problem might have initially fueled. Compare Casey Mulligan's study, "The incidence and magnitude of the health costs of in‑person

schooling during the COVID‑19 pandemic," _Public Choice_ (2021). Here is an un-gated link:

(Mulligan's working paper was circulated in winter 2021. The final MS is dated 21 May 2021.)

Mulligan writes:

"Abstract

The health costs of in-person schooling during the pandemic, if any, fall primarily on the families of students, largely owing to the fact that students significantly outnumber teachers. Data from North Carolina, Wisconsin, Australia, England, and Israel covering almost 80 million person-days in school during 2020 help assess the magnitude of the fatality risks of in-person schooling, accounting for mitigation protocols as well as the age and living arrangements of students and teachers. The risks of in-person schooling to unvaccinated teachers are, for those not yet elderly, small enough to challenge comprehension. Valued at a VSL of $10 million, the average daily fatality cost ranges from $0.01 for a young teacher living alone to as much as $29 for an elderly teacher living with an elderly spouse. For each 22 million unvaccinated students and teachers schooling in-person for a 5-day week during the pandemic, the expected number of fatalities among teachers and their spouses is one or less."

The upshot: Officials and regulators who closed schools could and should have known better. Many (most?) probably did know better. Corruption and pandering to squeaky wheels.

There is an interesting experiment underway that speaks to this issue I think: are expert forecasts of the election outcome (based on statistical models such as those published by FiveThirtyEight, the Economist, Silver Bulletin) more accurate than prediction markets (PredictIt, Polymarket, IEM). I am evaluating precisely this and have done so in earlier work.

I think the answer is likely to be domain specific. For elections, predictions markets may well be better. For hurricanes passing through population centers I would bet on experts.

More generally, it would be good to have an empirical program that tests these claims. And my intuition tells me that competition among experts and freedom of expression will be critically important variables to consider.
