If government is to have a dominate public health role it should (i) demonstrate institutional competence and (ii) be dealing with a well known problem with a well known solution.<br /><br />In the case of COVID institutional competence is questionable (e.g. too many regulatory burdens) but potentially fixable.<br /><br />But COVID has turned out not to be a well known problem with a well known solution and this has made the government role especially problematic. There is disagreement even now about how COVID spreads, what the best NPIs might be, how dangerous its is, who might have immunity. In the face of uncertainty heterogeneous responses of actors in the marketplace usually are a much better means of information discovery than government directed mandates or R&D. In many of its actions, government run public health has choked off that information discovery with inflexible regulations and lockdowns. Most of these have probably been done in good faith, but they have fallen prey to many problems identified by public choice economists.<br /><br />At a minimum these problems mean that government run public health should have taken a much lighter hand and been much more modest in its claims of knowledge.DWAndersonhttps://www.blogger.com/profile/11912588081258797990noreply@blogger.comtag:blogger.com,1999:blog-582368152716771238.post-39583813786085443842020-11-10T02:09:42.419-06:002020-11-10T02:09:42.419-06:00You are really missing the central point: Lockdown...You are really missing the central point: Lockdowns are a dispute for access to public space. You are simply siding with the people that want to use force to prevent one group from using this space (healthy people) so that the other group can use it (less healthy people). Do you have scientific evidence that this has any impact on the rate of transmission? Not even that... But you want more use of force.<br /><br />I honestly find it very disturbing that even "libertarians" supports this type of tyranny.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-582368152716771238.post-7115272289262747352020-11-09T23:27:15.003-06:002020-11-09T23:27:15.003-06:00From your list of 'appropriate government func...From your list of 'appropriate government functions', your revealed philosophy falls into the category 'classical liberalism', and not 'libertarianism'.<br /><br />See "https://en.wikipedia.org/wiki/Right-libertarianism" for an interesting discussion in contrast and comparison between the various 'schools' of libertarianism and between 'libertarianism' and 'classical liberalism' or 'neo-liberalism'. 'Libertarianism', and 'libertarian' differ from 'classical liberalism' and 'neo-liberalism' in significant aspects. For example, F. Hayek and M. Friedman, according to the article, referred to their economic philosophies as 'classical liberalism' (now referred to as 'neo-liberalism').<br /><br />The term 'liberal' has become so strongly associated with a particular political party in the States that there is an understandable desire to avoid using the term and variations on the term to describe political and economic philosophies that differ markedly from those associated with that particular political party. <br /><br />'Libertarian' is a term that differs sufficiently in sound and context from 'liberal' to serve as a differentiator, but it is incorrect as a label for what is, philosophically, classical liberalism.Old Eagle Eyehttps://www.blogger.com/profile/05270080708077871311noreply@blogger.comtag:blogger.com,1999:blog-582368152716771238.post-44731951391250683762020-11-09T17:15:09.831-06:002020-11-09T17:15:09.831-06:00Anecdotally, as soon as Las Vegas casino opened up...Anecdotally, as soon as Las Vegas casino opened up, there were a herd of people outside who poured in like it the Superbowl.

The positivity rate of testing in NYC was over 50% during the first peak but only 1.8% now that many neighborhoods are full of recovered people with some resistance ("immunity"). New virus hot spots are least likely in places that have already been hit hard. The April wave was concentraged in the Northeast which therefore was relatively untouched by second and third waves. The second July wave hit the South, which had largely escaped the April crisis). New outbreaks have largely been concnetrated in the Midweast and sparsely-populated Plains states, which escaped April and July waves. As odds of reinfection fall because of fewer susceptible targets, the virus reproduction rate will fall below 1 so that new cases will no longer replace those recovered and dead. A vaccine will accelerate this same process and, since it must be rationed for months, will narrow the scope of new infections to the young and healthy who will later be at very low risk of reinfection (exactly as if they had been vaccinated).

The hypot...I had a variant of this thought as well. The hypothesis is that R drops as superspreaders get infected and recover, choking off further exponential spread. But then patterns of behavior change and there is a new group of superspreaders and you have another wave. (Simple example: in warm weather the receptionist at the pool can become a superspreader, which changes to the receptionist at the health club in winter.) <br /><br />Overlaid on this phenomenon is the virus moving to new geographic locations that have not been hit hard before. These have been somewhat isolated previously, but once infections reach these locations they find a whole new group of spread patterns through which the virus runs.<br /><br />There are probably other aspects of the way that the spread works that are not well understood, but that could certainly produce this pattern.<br /><br />Perhaps much more testing or banning parties would have curtailed the spread more, but I am not so sure.DWAndersonhttps://www.blogger.com/profile/11912588081258797990noreply@blogger.comtag:blogger.com,1999:blog-582368152716771238.post-51212906456431272572020-11-09T08:17:10.875-06:002020-11-09T08:17:10.875-06:00"But our governments are supposed to be smart..."But our governments are supposed to be smarter than cows." I think the state governments are acting fairly rationally here. Regarding news of covid cases, direction of change is much more salient than magnitude of change, so the increase in approval rates from a large drop in cases is not much larger than the increase from a medium-sized drop in cases. Thus states relax restrictions when cases are falling, which boosts approval rates further. My alternative theory is that if states get the # of cases really low, then an influx of cases from surrounding states could bring news of huge percentage spikes, which is bad for approval rates.

It is exactly like federal spending, federal spending gets congested and caused a regime change every eight years, generally. In fact, the math that connects path search and differential equations over the Z plane was discovered by a research at Microsoft some twenty years ago, then he died in a mountain climbing accident.<br /><br />Toot your horn, but see if my post gets past the mark.Matt Younghttps://www.blogger.com/profile/08404998406161097199noreply@blogger.comtag:blogger.com,1999:blog-582368152716771238.post-72483649077930450602020-11-08T21:24:08.188-06:002020-11-08T21:24:08.188-06:00Until the end, I thought you might be referring to...Until the end, I thought you might be referring to the governments of Sweden and Japan.
