The government's Coronavirus policy is driven by many factors, but R0 number (the reproduction rate) seems to be the PM (Jacinda Ardern) preferred indicator. The reproduction rate depends on total infections. There are more papers posted now arguing that total infections are understated especially when "testing" is lacking. So R0 is understated too. The official R0 is less than 0.5, maybe it is more than 1 or even higher.
Conversely, the good news is that the death rate would be smaller than what we have, which is already relatively small. (death rate is number of deaths / infections). Should death rate be the guide for successful policy? I think so.
But what about those asymptomatic people who are infected? If indeed we have more infected people than we can tell, and we relax the lockdown to level 3 or 2, we could have a spike of infections and deaths next month. I think that effective testing can resolve the problem. Those who test positive get quarantined and treated and those who test negative go back to work. The question is about testing every person, and quickly. Testing, however, requires money and resources.
It was reported that the government is looking into the proposal of the Chief Economist of the Kiwibank Mr. Kerr to give people cash, maybe 6 billion dollars. Cash gift is an ineffective stimulus. The theory of consumption predicts that people do not spend windfalls. A few desperate people might, but there will be no significant increase in consumption. Deposits in Kiwibank might go up a little :) A better way to spend the money, in my view, is that the PM Jacinda Ardern spends it on testing. Test every person, and do it before the end of the year. Hopefully a vaccine will be available early next year.
