Vaccines, Lock-downs and Passports

 Vaccines, Lock-downs and Passports

Effect of Vaccines

     Our colleagues on the continent seem to be looking to the vaccines as a way of curbing a rampant spread of the virus. It might be worth pointing out that in Great Britain there was no discernible beneficial effect of the vaccination programme on daily new cases; only on daily deaths, which they have enormously reduced. What is needed to curb in infection is stricter lock-down.

     From 5th Jan 2021 till 28th Feb the semi-log plot of Log10 (daily cases) shows a monotonic decline with a halving time of 17 days. Since 1st March there seems to be a new slower rate of decline -- t(0.5) = 125 days. The epidemiological R number must be getting very close to 1.0. Perhaps this is the result of a return of children to schools,  or perhaps a general relaxation of vigilance; an unexpected negative effect of vaccination. (See my previous posts to understand these calculations.)

Fig. 1 Plot of Log (base 10) of daily case vs Days in 2021.

    I was hoping to see a slowing effect on transmission towards the end of January as the numbers of people vaccinated reached 9 million, but perhaps that was naive. The over-75-year-olds were always taking pretty good care of themselves; so the vaccinated people never were the 'spreaders'. They were, however, contributing to the hospitalisations and deaths. 

     Fig. 2 shows a semi-log plot of the logged death data averaged over the preceding 7 days, in order to smooth out the enormous dependence of number on day-of-the-week. There was a lag during January, while the lethal effects of December and Christmas took their toll. But from the beginning of February there has been an accelerating fall in daily mortality. The March data (pink squares) show a halving time of 11.2 days. And the decline is still quickening.

Lock-downs

     Transmission can be controlled quite effectively in the absence of vaccine, but it takes discipline. If everyone took the precautions that the vulnerable and careful people have been taking for the last 12 months, the daily number of new cases should drop suddenly to zero in the space of 5 - 7 days. Britain has never got anywhere near that degree of discipline. 

Vaccine-passports and Lock-down

     There has been some talk of letting people into pubs if they show a card that confirms that they have been vaccinated. Many seem to favour the idea; many are opposed.

     Once everybody in the country has been offered a vaccination, it does not seem necessary to request a passport. Those who wish to remain un-vaccinate will be taking a risk. But that is up to them. They should pose little threat to others who are vaccinated.

Fractional Reserve Banking and Asymmetric Risk

Have banks sufficiently reformed? 

    I see one issue to be 'fractional reserve banking', and a second to be 'asymmetric risk'. (This essay is a re-posting from March 2012)

    The pressure on bankers to over-lend is what brought about the recent sub-prime mortgage debacle. So we must reduce the temptation to make risky loans. And increase the penalties for bad loans. There seems to me to be no reason why banks should keep the interest when they lend money they do not own. So my first simple suggestion is that the tax rate on profits from lending should be related to the capitalisation of the bank. When a bank lends 10 times its capital, 90% of the interest it receives should be taxed away, leaving it only 10%. If it lends twice its capital, it retains half the profit. Simple!

    It may be objected that when a bank lends out money, albeit money that it does not own, it runs the risk of not getting it back, and the interest is the compensation for that risk. That argument fails if the banks are bailed out by the state.

    Banks operate to match loans to clients. If a loan defaults, the bank must certainly loose its share of the loan (10% or 50% in the above examples), but maybe should bear a stiffer penalty. The 19th century mechanism was to let the over-extended banks fail, and then to lock up the board of directors for debt, or fraud. That worked well enough to inculcate 4 generations of prudent banking and 130 years without a serious bank run; but the hardship to hundreds of thousands of innocent depositors is now regarded as intolerable, and governments tend (it seems) to step in to supply the missing money. 

    Fine, but I see no reason why the insolvent/imprudent bankers should escape, as they seem to be doing. Have any gone to prison? Has anyone drawn up a list of directors who would now be bankrupt were it not for the state's intervention? Or a balance sheet of the money that must be repaid to the public by the banking sector, bank by bank? This failure is not only unjust, the risk-asymmetry is very dangerous. Gambling for the bank is (currently) a case of "heads I win, tails you lose". An idiotic situation. The money must be recovered, however long that takes.

    So my second simple suggestion is like the first: "tax or fine the banks".

One Justice or Many?

 One Justice or Many?

"Half of the decisions of the US supreme court are 'arbitrary'; you might as well toss a coin as go to the court."

Should the 9 judges of the USA Supreme Court all come to the same conclusion, or may they come to different conclusions? If they are not unanimous, are some right and some wrong?

      My attention was caught by Randall Kennedy's article in the London Review of Books 21st Jan 2021; in the context of the contentious nomination by Donald Trump of Amy Coney Barrett as a Justice of the Supreme Court in the last 2 months of his term as president. Should Trump have waited? Should justice depend on which president nominates the Judge? 

        Kennedy titled his piece "Cynical Realism" and claimed he was such a realist. But are we all so cynical as to suppose a Republican appointed judge will automatically disagree with a Democratically elected judge? Apparently, this type of political bias is a recent phenomenon in the USA, appearing strongly only in the last 10 years. For the preceding 2 centuries it was quite common for Republican presidents to nominate left-leaning judges, and vice versa. But of course, it becomes a race to the bottom: "If you are going to be like that, I shall too". 

In Britain, we have only had a Supreme Court by that name since 2009. Prior to that the law lords in the House of Lords served that function. Our court has 12 judges. And our system of nomination is different; a 'name' drifts up out of a professional body to the Justice Secretary, who passes it (if he wishes) to the Prime Minister, who passes it (if he wishes) to the Queen, who makes the appointment (if she wishes).  Judges are assumed to be impartial and unbiased.

It would be naive to suppose that this way of appointing judges makes the British Supreme Court judges less inclined to bias. Of course they will be biased. But it will be harder in the British system to find an obvious label for the bias (like a political party label).

In the USA, some 36% of Supreme Court decisions are unanimous (9:0), 51% of decisions have a unanimous or preponderant decision (9:0, 8:1, 7:2).   But 49% are evenly split (6:3, 5:4). That is where the problems arise. The general public are inclined to ask: "How can a decision be regarded as right when half the panel vote against it?".  A split verdict cannot justifiably be called the "Right" verdict. In fact it could be called "Arbitrary"; you could as well toss a coin and move on.  Such decisions produce a general feeling of dissatisfaction and disappointment; a feeling of cynical realism.

In Britain, though there are 12 judges on the Supreme Court, most cases are heard by only 5 judges, though occasionally 7 or 9. In all the dozen cases I picked at random from the last 4 years, the judgements have been unanimous. (And it may be added that in each case the judgement was to dismiss the appeal and uphold the decision of the lower court.)

Is it too simple-minded to think that there is indeed a right and a wrong answer? I think not. I believe the "right" decision is definable in terms of a sufficient number of sufficiently well trained and sufficiently deep-thinking judges? The Court should be sufficiently large and sufficiently unbiased to constitute a representative sample of such a "judiciary". Justices should know the case-law of previous decisions, and should be able to see the implications of a decision. Not just to the case in hand, but the future consequences of their decisions in terms of a heterogeneous society. Such a court should be asked to come, not to a majority, not even to a consensus, but to the "right" decision. As Quakers are enjoined to do in their Meetings for Worship for Business.

I would be inclined to lock the judges in a room (like cardinals during a papal election), and wait until they had achieved a unanimous (or at least a preponderant) decision.

Third Lockdown is weakening

 Third Lockdown is weakening

        The prevalence of SARS-CoV2 virions in the UK (as a whole) is still falling. This is shown in the green and blue portions of this semi-log plot of [Log (daily case increment)] against day (before or after the 1st Jan 2021). 

       However, it is no longer possible to draw a convincing single line through the data-points since 5th Jan 2021. The green points show data from 5th Jan to 2nd Feb, where the halving-time is 15.8 days (0.301/0.0191). The blue points represent data from 2nd to 26th Feb, where the fitted line has a slope corresponding to a halving-time of 21.97 days (0.301/0.0137). (See my previous posts on the pandemic for details of this type of plot, and argument. The red data-points show the logarithmic spread of the virus during December.)


       To my eye, it is the data from the last week (from 19th to 26th Feb) that show the tendency to bend upward. I suppose it is Lock-down Fatigue, perhaps with a touch of Vaccination Complacency.  Or perhaps a knock-on from Valentine's Day. But it is a little worrying, and needs to be heeded. (Not, please, our ridiculous 'head-in-sand' behaviour displayed by our government and media during July and August 2020, commented on in my https://occidentis.blogspot.com/2020/09/covid-19-case-data-uk.html.)

Tax Fat Cars

 Tax Fat Cars

I think the government should think about putting a tax on extra-wide cars. It might turn the trend away from ever-wider and wider models, which would save an awful lot of bother and expense, and at the same time raise a little revenue to pay for the damage done to our roads. 

Fat cars are as much of a nuisance in a carpark as they are in a narrow lane; for their owners as well as for everyone else. And in a subtle but undeniable way they are somewhat insulting to the 'ordinary' person (who is content with an 'ordinary' sized car). Only by driving with extreme humility can a fat car owner avoid the implication that he or she thinks they are 1½ times as important as their fellow road users. The wives sometimes manage it, by looking helplessly lost in the great space of the interior, while they grip the great wheel and peer over the dashboard, slowing to nothing as they approach another road-user. But the husbands seldom try, preferring to display their road-skills, and panache.

Of course, cars are getting bigger and heavier because they incorporate ever higher safety standards; as is pointed out by Richard Bremner in the August 2019 number of Autocar (https://www.autocar.co.uk/car-news/features/investigation-why-are-cars-becoming-so-wide). But I am not talking about the merely-wide; rather the too-wide, and the unnecessarily-wide.

Cars that are over 2 metres wide automatically fall in this category. But I think it would be fair to bring the road-fund 'super-tax' in at 1990 mm.

Car                                                    Width (mm)

Landrover Rangerover sport                1990

Audi Q8                                                1995

Landrover Defender (90/110)              1996

Bentley Bentayga                                 2010

Landrover Discovery (mirrors out)      2220



You see, I am thinking of the inconvenience to fellow road users, as well as the damage to our roads. It is bad enough when a wide car meets a normal car. But as the frequency of these giants increases every year, there will come the time when a fat car meets another fat car. Something has to give. Richard Bremner recounts a London traffic jam caused simply by the fact that a Bentley Continental GT and a Range Rover were unable to pass one another in an ordinary street. The resulting jam took 20 minutes to clear. 

If the verges are soft, it is the verges that have to give. Think of the cost to the public purse of repairing or widening the 214,900 miles of minor roads that we have in Britain. If we cannot halt the trend towards wider cars, we can at least start to put money aside to repair the damage.

We anxiously watch for the effects of the Vaccines

  We are very proud of and grateful for our dedicated NHS staff. They are working their socks off to get the two vaccines (Pfizer and AstraZenica) distributed where they will (a) save lives, and (b) bring down the number of circulating viruses.

        I have been following the numbers of new COVID-19 cases reported in the whole of the UK each day on the excellent government website. I plot the logarithm of that number against the day. In December 2020, under a confused and heterogenous tiered system, the virus continued to spread; logged data (pink symbols) rise more-or-less monotonically, with a doubling time of 16.3 days. After Christmas new lockdown was imposed. Since 5th January the logged data (blue symbols) fall more-or-less monotonically with a halving time of 16.3 days. (During the first lockdown, in May and June, the falling incidence showed a halving time of 19.8 days, so this January 2021 fall is marginally faster.)
        Vaccination started at 8th December 2020, but till this time (end January) it has been largely confined to the over 70 age group. It is clear that this group, selected as the most likely to die of COVID-19, are not the group most likely to be the main spreaders of the virus.  
The December data (pink squares) show a steady rise, doubling every 16.3 days (rather ignoring Boris’s lockdowns, letups, and tiers, but maybe showing a slight upward curve as the 'Kent' variant spread.).
        So far, the data for the whole of the UK from 5th January fit a fairly steady monotonic decay curve, t½≅16.3days. (See Fig. 1. Remember, I plot (on the vertical axis) log [base 10] of the number of new cases reported on each day relative to 1st Jan 2021 (shown on the horizontal axis). Blue diamonds are January data to 31st inclusive.) I am sure that everyone is hoping to see a distinct acceleration in the decline of these transmission numbers, but that is not yet visible. 


(The preference for ‘reporting cases' on Fridays is very pronounced — 8, 15, 22, 29 in Jan 2021.)

Of course, the over 70 age group are not the major spreaders, So let 
us look at the Logged (and smoothed) data for the number of deaths on 
each day in January. Unfortunately, there is no convincing sign yet of a 
decline in the daily death toll. The data show only a strong dependence 
on the day of the week. Throughout January, Mondays are good days, 
with 2-3 times fewer deaths than found on Wednedays.

Is governmental COVID support causing Inflation?

 My Comments (in Red) on NotaYesman'sEconomics Post of 22 Jan 2021 

I find Shaun Richard's blogposts on the economy invaluable, but also immensely frustrating. He is well informed and keeps a close eye on the market and the operations of the Bank of England and other central banks. But his command of written English is appalling. 

I believe his latest blog-piece (that of 2021-01-22) concludes that massive governmental injection of money in response to the COVID-19 pandemic is causing signs of inflation in the December 2020 figures for UK retail sales. 

Retail sales may be up 2.9% this December compared with 2019 (see below), but the official (CPI) measure of inflation is only up 0.65% on December 2019.  (Is the CPI therefore wrong?)  However, it has been a funny old year. I am buying far more more books this year than last, but I am spending far less on petrol and air travel. I do not think I have been influenced by interventional government spending schemes. I would take with a cautious "pinch of salt" the conclusion that deficit-funded Government spending has caused appreciable monetary expansion, as yet. (But maybe I have missed Richard's point.)

&%&%&%&

Thus, Shaun Richard writes: 

The main (interventional) schemes are listed below.

§  COVID-19 Corporate Financing Facility

§  Coronavirus Job Retention Scheme (CJRS)

§  Self-employment Income Support Scheme (SEISS)

§  Eat Out to Help Out

§  Miscellaneous subsidies paid out to businesses

"Of these the first does not involve the public finances at this stage as the Bank of England has lent some £12.3 billion in the CFF. It may appear if there are losses on the scheme but as we stand we see simply some implicit support for retail sales. " (Or: Of these the first does not appear as a debt in the public finances at this stage, as the Bank of England has merely "lent" some £12.3 billion into the CFF. It may appear as a debt if the loan is not repaid; but at present we see simply some implicit support for retail sales.).

****************************************************************************************

"Sadly the Office for National Statistics has turned its blind eye to this issue (of swings) and never produced (does he mean 'published'?) the research which was done (please punctuate) which leads me to conclude it favoured the Retail Price Index. (Over what? The CPI?) But the inflation issue is for another day except (to remark that) we have an area where out (our?) official statistics office has a disappointing track record."
