Truth Is The Daughter Of Time

This is a frontispiece to a 1951 mystery novel by Josephine Tey (real name: Elizabeth Makintosh) named _The Daughter of Time_It is about the question of whether or not King Richard III ordered the murder of the "Little Princes in the Tower," his nephews Edward and Richard, as has  long been alleged, and for a long time was simply accepted as historical fact.  This bestselling and very well and wittily written novel makes the case that Richard was framed by his successor, Henry (Tudor) VII, who usurped him after defeating and killing him in the Battle of Bosworth Field in 1485.  Tey manages to build up through the novel a very convincing case for this view, which I shall not get into the details of, although I highly recommend the novel, which I just finished reading. In any case, if she is right, or even partly right (because  have been many other accusations against Richard made as well), then this is one of those cases where "the victor gets to write the history."

I note a few points.  The usual argument, still put accepted by many, is that Richard did the little princes in because they were  threats to his having succeeded their father, his brother, Edward IV.  But in fact it is now accepted (documents surfaced centuries later on this apparently suppressed by Henry VII) that  showed that they were illegitimate and thus not possible heirs to the throne. Richard had no reason to kill them.  He was invited to assume the throne by both houses of parliament and was thus completely legal and legitimate. And after his death, Henry had a Bill of Attainder brought against him in parliament listing all sorts of terrible things he supposedly did that justified the completely illegitimate Henry usurping Richard's throne.  But murdering the princes was somehow not included in this Bill, which would obviously have been the top charge against Richard if  it  were true.  Furthermore, given Henry's lack of any legitimacy, there was a large group of individuals, including the little princes if they were still alive, who had more claim to the throne than Henry.  He  was the British monarch who initially instituted Star Chambers that brought charges against each of these in turn allowing them to be "judicially murdered." The  grounds for these in some cases were as vague as "for certain reasons" (unnamed).  OTOH, a major reform Richard introduced was the right to bail.  There is much more, but this gives some idea of what Tey puts forth, most  of which I have verified from other sources.

I see a couple of relevances of this to current events, both the matter of arguments over "the Lost Cause" and Confederate monuments as well as the matter of whether ot not Donald Trump will get away historically with stating over 20,000 lies since becoming president.  There seem to be three factors here.  One is whether a leader can be authoritarian or not, which Trump would like to be but is not quite.  Henry VII certainly was.  This allows one many advantages in putting forth a false historical narrative.

Then there is the matter of having propagandists, especially initial ones.  For Trump that is clearly Fox News.  For the Lost Cause there was not a single clear individual or group, but a long buildup through the late 19th and into the early 20th centuries.  For Henry VII the most important was his ally and enemy of Richard, John Morton, whom Henry made the Archbishop of Canterbury, a thoroughly corrupt individual.  Much younger than him, but working for him, was the much revered Sir Thomas More, and it was through More that Morton put forth the initial claims and accusations against Richard.

Then we have the role of arts and media.  I do not think Trump really has that yet, which takes more time, ,but for the enemies of Richard the most influential was William Shakespeare, whose play, Richard III, written during the reign of the last Tudor monarch, Elizabeth I, depicts him as a truly monstrous figure, murderer of the little princes, slanderer of his mother, and much else, as well as being hunch-backed and with a withered arm, these latter all apparently false.  But he makes for a great villain, and the count of famous actors portraying him as such is beyond count.  Shaekespeare's play may be the reason more than any other why most people and many textbooks present the standard story as fact without any hint of doubt.  In many peoples' minds, Richard may have been the worst of all British monarchs, with only King John a possible rival (btw, his corpse was found in 2012 under a parking lot in Leicester).

While Trump may not have his Shakespeare, the Lost Cause certainly had its victory in the arts and media by the early 20th century in the form of Hollywood, most influentially with the films Birth of a Nation by Griffiths that glorified the KKK and the not quite so virulent but probably more influential Gone with the Wind.  Hollywood bought the Lost Cause hook, line, and sinker all the way and really did a semi-Shakespeare version on it.

BTW, another curious example of historical distortion that I knew nothing about is reported in the novel, and it involves monuments, which do certainly reinforce these historical myths.  I had  never heard of the Covenanters, but they were a radical Presbyterian group in Scotland that played a major role in making Scotland be predominantly Presbyterian, with the height of their activities being in the early 1600s, with a dramatic peak around 1638. Anyway, Tey (who was born in Scotland) reports on some monuments somewhere there to some women who were supposedly martyrs to the Covenanter cause.  However, according to her they were not even killed. They were not martyrs at all. But the monuments and claims they were helped the cause. Apparently the truth is now generally accepted, and occasionally somebody suggests taking down the monuments.  But somehow it does not happen because they make good tourist attractions for the small towns they are in.

More Likely Bad Economic Forecasting: This Time From OECD And CBO

That would be the quintessentially establishment and boringly conventional Organization of Economic Cooperation and Development, the Paris-based "rich nations'" entity that grew out of the Marshall Plan and has a reputation for excellent data, and also the Congressional Budget Office, generally regarded as bipartisan and highly professional.

So I saw their forecasts of US economic performance in terms of GDP and unemployment rates for the end of this year, and I find both to be highly unlikely, probably way too pessimistic.  I get these from a column in today's Washington Post by the often execrable Robert J. Samuelson, but here he is playing it straight and just reporting.  Indeed, the main thrust of his column is to note an apparent disjuncture between the hot stock market and the not-so-obviously hot economy, suggesting either the stock market is overvalued or the economy is being underforecast.  I suspect actually that both are true, although I am not going to attempt forecast the stock market.

Anyway, RJS reports two forecasts coming out of the OECD, one "pessimistic" and one "more pessimistic" for the US.  The first is sort of a baseline one that assumes the coronavirus is gotten to be more or less under control. The second one assumes a second wave of the virus this fall.  The first forecast sees a GDP decline for 2020 of -7.3%  with an unemployment rate at the end of the year  of 11.3%.  The second more pessimistic one has GDP declining -8.5% with a resulting end-of-year unemployment rate of 12.5%.

The CBO forecast, just one, is not quite as pessimistic. It sees GDP declining -5.9% for the year with the unemployment rate ending up at 10.6%.

Well, the latest unemployment rate is reported to be 11.1%, already lower than what either of the OECD forecasts see as the US economy having at the end of 2020.  That is above the 10.5% forecast by the CBO, but not by much, especially if one notes that the rate declined by about 2% in just the last month.  For the OECD projections to hold, the US GDP will have to stop rising, as it appears to be doing and go back downwards, thus giving us the infamous "W" pattern some have forecast, even without a second wave. The CBO forecast may not need an outright downturn, but it will need a pretty hard flattening to near zero growth soon to come true, something like the "square root" pattern that some have forecast.

Now most think the growth of the US economy is slowing, probably has been since sometime in mid-to-late June after the new infection rate took off again and we began to see renewed closings, although in some states reopenings are still happennig. But in fact most private forecasters have the US economy still growing, although there is much debate about how much (see Econbrowser for a recent post on competing forecasts, all positive for the near term).

I think it is impossible for the US economy to follow the forecasts coming out of the White House and its sycophants that would have the US experience a V-shaped recovery all the way to the election, with the US getting back to its "perfect" February condition.  But unless we do have a full-blown second wave, I think it is unlikely the unemployment rate will be over 10 percent come November 3, even if I am not going to try to pin it down more.  The OECD and CBO forecasts are not impossible, but I think they involve a very serious and ongoing full-blown pandemic continuation in the US unlike what we see in all but a handful of other nations.  And if Trump starts wearing a mask all the time and starts actively pushing his followers to do so, that may well bring the virus more under control and make those OECD and CBO forecasts and up looking way too pessimistic.

A Framework for Coronavirus Policy

There are two general ways to reduce the transmission of the virus.  One is “engineering”, changing the physical environment, the other is “social”, changing behavior to keep people distant from each other.  Under engineering we can include not only physical partitions, UV lighting and ventilation, but also mask-wearing and other PPE.  I know, there is a very large behavioral component to masking, but I want to focus on the distancing aspect, so let’s put everything else in the engineering box.

Now for distancing.  Suppose we know instantaneously and with certainty everyone who is infected.  In that case we can selectively quarantine them, and this will cut off transmission.  That is possible only in rare circumstances, such as a country that has fully eradicated the virus but has occasional external visitors.  If you have a reliable test you can identify anyone arriving with the disease and isolate them.  The rest of the population, known to be uninfected and unexposed, can move freely and congregate as they want.

A more realistic case is that you know with near certainty everyone who is infected, but only with a delay.  Then those who came into contact with them during their potential spreading period are also suspect and need to be isolated.  This is the idea behind contact tracing, which imposes distancing on a small subset of the population who may not be infected but leaves everyone else free to go on with their life.

Now what happens if there is some combination of too many cases, too little or inaccurate testing, and insufficient tracing?  This is where we are now, and the only recourse if we want to get control over the pandemic is to impose distancing on the entire population or as much of it as possible.  Only after this policy reduces the number of active cases to the point where testing and tracing can bring us back to the previous state will it be advisable to resume most congregating activity.

What it all adds up to is the notion that distancing is distancing, whether it applies only to quarantining those already infected, the larger group who have been in contact with those infected, or the whole population.  The smaller the number of people to whom distancing can be applied, the better.  The goal of policy should be to systematically move from the third case to the second and then to the first.

Cancel Culture: Retail vs. Wholesale

When my stomach can take it, which is rarely, I take a look at Marginal Revolution.  Tuning in today, I see Cowen predicting that the intellectual right  will become much more open to deviations in the future -- as long as all agree in being anti-leftist. And the latter involves, of course, the condemnation ad nauseam of "Cancel Culture." Look I don't like this retail stuff they go on about either, but isn't it rich to hear the GMU crowd, using Koch money and the influence it buys to keep the groves of their Academy  quite free of any left-wing ideas --wholesale Cancel culture, that --making the case!

Favoring Hi-Tech Tax Cheats Over Consumers of French Wine

Hoping to buy a nice bottle of French wine? Doug Palmer of Poltico has some bad news for you:
The Trump administration announced Friday a 25 percent tariff on $1.3 billion worth of French handbags, cosmetics and soaps in retaliation for a digital services tax on U.S. internet giants, but said it would suspend imposing them for up to six months. The United States believes the way the French tax is structured unfairly targets large U.S. internet companies like Facebook, Google and Amazon. However, other countries are increasingly determined to find a way to collect revenue from firms that earn billions of dollars in their markets.
Let’s note that Amazon, Facebook, and Amazon made yuuuuge profits and evade U.S. corporate profits taxes. So paying a modest excise tax on European sales is not exactly going to bankrupt these tax cheats. But back to the story:
U.S. Trade Representative Robert Lighthizer’s office concluded last year that France’s digital service tax was unreasonable, discriminatory and a burden on U.S. commerce. It also laid out a list of $2.4 billion worth of French goods — including Champagne, cheeses, handbags, soaps and fine dinnerware — that could be hit with retaliatory duties as high as 100 percent. U.S. trade officials said the final retaliation figure announced Friday reflects the value of U.S. digital transactions covered by France’s 3 percent digital services tax, which is estimated to be in the range of $15 billion per year, and the amount of taxes that France is expected to collect from U.S. companies.
If collecting tax revenues were the goal, the U.S. could make much more from Amazon, Facebook, and Google by simply enforcing the transfer pricing rules. Oh but that would be taxing rich people which is not the Republican way. Back to the story:
The final retaliatory list leaves off Champagne, cheese and fine dinnerware. U.S. wine wholesalers and retailers, who have already been hurt by a 25 percent U.S. retaliatory duty on European wine in a separate dispute over European government support for aerospace giant Airbus, fought Lighthizer’s threat to include French Champagne in the retaliatory list for the digital services tax.Industry groups estimated an additional 100 percent duty on French sparkling wine would increase the cost to importers by $718 million and cause the loss of more than 17,000 jobs throughout the distribution chain. A tariff of just 25 percent would boost costs by $179 million and jeopardize an estimated 6,000 jobs, the groups said.
Screw the little guy and consumers too. That’s the Republican way.

Being Targeted

Arguably this is paranoia, but the mayor and police chief of my city do not think so and have officially reacted with formal response.  What a sign that I am an old whatever, praising local law enforcement, but, well....

So the issue is that late last evening a truck full of masked white men, and no, we are not talking health masks but ones that cover ID, with flags waving including the Confederate battle flag, were going up and down our block taking photos of certain houses, including ours.  What did these objects of this photographic effort find consistent?  We all had posters on our property declaring "Black Live Matters." Many on our block became upset over this, including my wife, and now the City of Harrisonburg, VA  police are specially watching our block. I note that both the  mayor and police chief of our city happen to be Black, for which at this time I am grateful.

Background here is that I have been living where I am for 32 years with my wife, Marina, in a block in Old Town of Harrisonburg, VA, where most of the houses are somewhat over a century old, and we are five minutes from the central square, as well as being 20 minutes from offices at James Madison University.  Where we are is given by the 2004 prez election.  There are 5 precincts in Harrisonburg, but ours, closest to JMU, was the only precinct in the entire Shenandoah Valley that went for Kerry over Bush. Yes, we are an island of "liberalism," with Harrisonburg later in 16 going strongly for Bernie.

So I happen to live on the most publicized block of all of this Old Town, which I note for the record has both Trump supporters in good number as well as Republicans who  are not big fans of Trump.  There has been a long history of the local newspaper focusing on our block in particular [Daily News Record owned by family of the late racist Harry Byrd], with even our house appearing twice in stories in this paper representing the neighborhood [we have a nice garden in front]. I note  here that our block is a super fave on Halloween for trick or treaters, many hundreds coming from outside the city.  We do our best to treat them well.

Our neighborhood, heavily crawling with  JMU faculty, is certainly mostly an upper middle class neighborhood,  But while being mostly white there are Blacks as well as various people from abroad from all over the world. So we are fairly diverse these days.

Anyway, several weeks ago a friend-neighbor up the street starting putting out these Black Lives Matter signs, costing I think 3 bucks or so, that one could put in one's yard. They went all over town, but our block got more than anywhere else, with where I live 5 of us in a contiguous row puttng them in our visible front yards. At least one of those in our row is a Republican family..

Death Comes To My Old Economics Department

That would be the one at my alma mater, the University of Wisconsin-Madison.  I have learned that on July 6 one of its current members died, Bill Sandholm, an excellent evolutionary game theorist who was about 50 years old.  It is a sign of my age that he always seemed quite young to me, barely older than my oldest daughter, and now he is dead.  He was a very nice guy, aside from being a very capable economist who was the Richard Stockwell Professor of Economics and once helped me out with a paper that was in a Revise and Resubmit condition.

I bring this up because there is an unconfirmed rumor that he died of complications of Covid-19, with for the moment nobody that I know, including members of the department, knowing what he died of.  If the rumor is correct, he will be the first person I knew personally to die of this dreadful pandemic.  It does bring it rather home.

It also does so because it probably puts the final nail into any plan to visit Madison this summer, which I have done almost every summer if for no other reason than having family members there I wish to see, not to mention some friends still, and it being a very pleasant place to visit in the summer, cooler than Virginia where i live. Indeed, Plan A had been to be there last weekend, but that got put off due to the pandemic.  I had still thought of possibly going maybe at the beginning of August or thereabouts for a quick pop-in.  But now apparently there has been a new spike of cases there and in Wisconsin more broadly, something my daughter who lives there had informed us of just in the last couple of days accompanied by discouraging noises about trying to go there.  And now I have learned about this new development, although it may be that the rumor is false.  But it does seem to be a final hammer hit on any plans to visit that fair city I am so much attached to for now.

Worrying About November 3, 2020

Sigh.  So the US election is now just four days less than being four months from now, and, really, anything can happen. After all, four days less than four months ago was March 11, just before the US fully recognized  that we were in a pandemic, with everything closing, and "the economy falling off a cliff," as it is now put, but was not obvious  on 3/11 at all, even though it was only about two days away.  And the murder of George Floyd was still some time off.  So, the world can turn completely upside down before the election, and nobody should forget that what really matters is what happens in the two weeks before the election, the period of short-term memory, and that really cannot be foreseen.  I mean, those who hate Hillary a lot say it was not a big deal, but most of us realize that if James Comey had not made his big announcement about new nothing investigations of  her emails 11 days prior to the election in 2016, she almost certainly would be running for reelection right now.

So, we are in this obviously ironic position: may Dems are hoping things go badly in the next four months while many GOPs are hoping just the opposite, just so each gets the electoral outcome they want.  This is nothing new, but it does put forward ironies in an unprecedented situation with many  bad things happening and general uncertainty simply super high.  Thus we have the oddity that in Congress it is Dems who are pushing for more and more expansive fiscal stimulus, which would presumably help the economy and thus Trump's reelection chances, while it is GOPs, especially in the Senate where they are in control, who are being the most negative about such a package, especially because of its aid to states and localities, whom they view as Dem interests.  I see out of the White House that Trump himself understands this and would like to see more fiscal stimulus, if perhaps with some limits and conditions.  But, heck, things are indeed fully topsy-turvy.

So, keeping in mind that anything can happen, and I mean seriously all sorts of currently completely inconceivable things, I am going to worry about how if nothing dramatic happens, we could see gradually improving trends on several fronts that could move the November prez election back from its current state where if it were held today Biden would simply blow out Trump and the Dems would easilly take control of the Senate, back more to what was where things were before four months ago, where it looked like a close race in November, both for the White House and the Senate, with Biden's chances probably better than those of the Dems taking the Senate.

Clearly the fundamental driving force will be what happens with the pandemic.  Right now it is getting worse, at least in terms of new cases, in the US, although that has declined in the last few days from over 50,000 per day to the mid 40,000s.  I think it is highly likely we shall see another peak on that due to the gatherings for July 4, but if in fact governors react more strongly and start seriously emforcing mask wearing and all that, we might well see that peak in two weeks as the peak, with a gradual decline going on after that.  Of course there are numerous chances for it to explode again, with the opening of schools in the fall one such obvious possibiity.  But note that most of the rest of the world where they have been serious about mask wearing and social distancing have gotten their cases way down, with them so far staying down.  If the governors get tough, nothing due to Trump, we might see the hot new hotspots getting under control in a few months, especially four months.

Heck, next dooe to where I am in Virginia is Pendleton County, West Virginia.  It is currently the most pro-Trump state in the nation, and also one of the five least infeeted.  My county cite-county has nearly 1700 cases, but Pendleton has a mere 12.  But yesterday GOP WVa Gov. Jim Justice just imposed a statewide requirement to wear face masks in public.  Trump may not get it, but if the GOP govs get it, that might be sufficient to get things much more under control than they are now.

If the virus gets under control, well, then the economy can reopen again and start growing again.  I have already posted on how the US economy has done better than forecast by many.  Now most of us are forecasting a slowdown due to the reemergence of the virus and the new shutdowns.  But while many states are doing new shutdowns, some places are still in their first rounds of reopening.  Heck, here in Virginia, July 1 marked the arrival of Phase 3 of the reopenings, and VA is ahead of DC and Maryland on that. Reopenings, with accompanying heightened GDP growth are still going on.  As it is, I am not forecasting how the economy will do, but it is not at all out of the question that it might be doing not too badly come November, although I am sure unemployment will still be higher than it was four months ago. But on the stock market, heck, the NASDAQ is already at new record highs.

I am not going to speculate about the Black Lives Matter movement, but certaintly that could go in a lot of directions, and the political bottom line on it by November could be much different than it looks now.

So, bottom line is nobody should get complacent that Trump will lose, although I find those who predict that he will definitely win to just completely silly.  Everything is uncertain and up in the air.

Blowing Smoke

The President's keeps saying that the US has the lowest Corona-virus fatality rate in the world.  And he keeps talking about how we have a high number of cases because we test more. The game he is playing is evident, but I keep waiting for  the talking heads to point it out and being disappointed. He is referring to the US case-fatality rate, not the per-capita fatality rate. More testing lowers the case-fatality rate (deaths/case), simply by increasing the denominator. But it simultaneously raises the infection rate (cases/population) by the same proportion, leaving what we are really concerned about, the per-capita mortality rate (deaths/population =(deaths/cases) * (cases/ population)) unaffected. And on this measure, the US is the 7th highest in the world, at 39.82 deaths per 100,000. (I  ignore San Marino and Andorra, because the measured rate is meaningless with such tiny numbers). We are below Italy, Spain, Sweden, the UK, Belgium, France. But we are far above Germany (10.88), Canada (23.61), Mexico (24.66), Iran (13) and a host of others.

Wildly Off Forecasts?

The macroeconomic forecasting business has become quite unhinged in the current situation, with existing models seeming to have their wheels coming off as old relationships simply do not hold and reported data seems unreliable and going in all sorts of directions.  We have already seen this happen regarding forecasts that were made for the May employment numbers, with most forecasters projecting employment declines that would have been more than 10%, some of them by a lot more than that, although none more than 20%. But in the end employment was estimated to have grown by over 2%, a situation of the forecasters simply being wildly wrong.

As it is, with the month of June now over and thus the second quarter over, it looks increasingly to me like most of the forecasters have not learned their lessons from that May employment fiasco.  I suspect that in many organizations they find it hard to revise their models, especially on short notice, even when it is clear their models are not working.  We see a lot of the forecasters making predictions of a large second quarter decline in GDP, but more numbers have come out for May, and most of them have been positive, some of them very positive, and if June continues to be positive, even if at a lesser rate than May given renewed shutdowns occurring due to the uptick in Covid-19 infections as June proceeded, this may further make some of these strongly negative forecasts even further off.

So what are some of these forecasts and what do the latest reported numbers look like?  First we must note the first quarter outcome.  It seems that GDP declined by -4.8% or 5.0% for the first quarter at an annualized rate.  All of the decline occurred in March, more than offsetting modest growth in both January and February. 

But the forecasts for annualized rates of decline for the second quarter are awesome, at least most of them.  I am getting these from a post by Menzie Chinn over on Econbrowser and are from less than a week ago on June 26.  Here are some:
GDPNow -39.5%
New York Fed -16.3%
St. Louis Fed -38.16%
IHS Markit -35.3%.

Clearly rhe only one not showing a massive decline is the New York Fed.

Menzie  also showed how the forecasts have evolved for two other forecasters.  A blue chip group's forecast was for a -25% rate on April 30, but slid to -35% by June 5.
The Atlanta Fed has had its forecast make large movements, starting out at a relatively modest -12% as of April 30, but then plunging to a whopping -54% as of June 5, but then in the face of more recently improving data by June 26 this forecast had moved to not a not quite as whopping -40%.

So what does estimated data look like?  One estimate I have seen for the month of April had the actual decline of GDP being -11.4%, which translates to about a -42% annualized  rate.  But we already see here the danger for all of those forecasts listed above except for that of the New York Fed.  It is near certain indeed that the economy has been growing in both May and June.  If so that annualized rate of -42% looks to be a definite outer bound.

Now if there has been barely any growth in May and June we might still see numbers in the 30s for the annualized rate of decline.  But at least for May the numbers do not look like that.  We have already seen employment grow at over 2%, which is the actual growth, not the annualized, which is much higher.  We now have an estimate for consumption, which grew at over 17% in May. Given that consumption is on the order of 70% of GDP that is pretty much the ballgame right there, barring some sharp turnaround in June.  This is especially the case as estimates of construction also seem to show sharp growth in May, a major component of investment, although if inventories fall sharply, that might offset the construction increase.  State and local governments were almost surely declining and probably still are, but probably not a massive rates.  Trade is especially hard to predict, with indeed net exports appearing to decline in April by somewhere between -7 and -16%.  But exports might actually be rising now as much of the world economy appears to be growing again.

The apparently steep decline of GDP in April will be hard to overcome during these past two months.  But it is not out of the question that we might actually see a slightly positive figure for the quarter, especially if it turns out that growth in June continued to be as strong as it looks like May was.  But even if it flattened out some as I suggested might happen in a recent post, it looks to me that the sharply negative predietions still being held to by so many forecasters simply look to be way off.  Even the much less negative New York Fed may prove to have been too negative, even if indeed the quarter outcome is still negative overall for GDP growth, with it probably going to be more than a month before we shall know at all reasonably.

I conclude by noting that even if second quarter is positive or only mildly negative, growth prospects going forward for the near future look less promising.  This is not only because of the recent spiking of Covid-19 cases with associated shutdowns, but also because portions of the large fiscal stimulus that has been going on and has probably aided the recent growth will have disappeared or will do so unless Congress acts to keep them going.  In particular, the individual stimulus checks have ceased, and the expanded unemployment benefits are scheduled to cease at the end of July.  What is more certain is that we are truly profoundly uncertain about what will transpire in the next few months.

Going Too Far

Unfortunately it was going to happen, and we who support the movement need to call out those instances where it goes too far.  I am talking about the justified Black Lives Matter (BLM) movement, mostly characterized by widespread peaceful protests even in small rural towns that never see such things, and with a solid majority of the American people currently supporting both the BLM and its main demands.  As it is, one should probably not tie the BLM to some of these recent unacceptable events, although those engaged in them will justify their actions as being part of the movement. This should not be accepted.

OK, the one that has really put me off happened last night at sometime after 10:30 PM in Madison, Wisconsin.  A statue I know well was not only pulled down, but it was decapitated with both parts thrown in a nearby lake, although apparently since recovered. This statue stood on the east corner of the Capitol Square downtown.  It is of Hans Christian Heg (1829-1863).  An immigrant from Norway, he was an active anti-slavery abolitionist and member of the Free Soil Party who led the 15th Scandinavian American regiment in the Union army.  He died fighting against the Confederacy in the Battle of Chickamauga, which it says on the base of his statue.  There is absolutely no justification for this event.

This was accompanied by other pretty unacceptable nonsense. The "Forward" statue at the opposite end of the square was also pulled down and dragged down State Street.  This is of a generic woman representing the state motto of "Forward," not quite as completely insane as pulling down Heg, but also without any obvious justification.The Forward motto and idea has long been associated with the Progressive tradition in the state, although I suppose one could drag in bad stuff about some of those folks, such as that some supported eugenics. But I do not think this crowd was thinking about that.

What triggered this? Apparently a man entered a restaurant with a baseball bat and a bullhorn, with which he began to harangue customers. He was later arrested for disorderly conduct, which sounds pretty reasonable to me.  There was no violence or other impropriety in his arrest.  But the crowd that pulled down the statues and smashed a lot of windows and attacked a state senator, putting him in the hospital for taking a photo of them, came several hours after his arrest to protest his arrest.  Bah!

I note two other items that need to be disavowed and opposed by supporters of the BLM. 

One was the tearing down of a statue in San Francisco of U.S. Grant. allegedly because for two years he owned a slave he inherited before he freed that slave. Well, I guess there is more case for pulling down his statue than that of Heg, for which there is zero. But he was not only the commander of the Union army that freed the slaves, but as president he supported Reconstruction that defended rights of the freed former slaves. The move to Jim Crow followed the end of his presidency.

Another is the continuation of the CHOP or CHAZ in Seattle, which, I gather, will be ended fairly soon one way or another.  Initially sort of interesting, the area has been hit with shootings over the last four nights, with one over the weekend killing 19-year old Lorenzo Anderson.  These are apparently not he result of outside white boogaloo racists attacking them but coming from inside this area.  There so far has been zero investigation of or effort to find Anderson's murderer and arrest him.The only report I have seen is that Anderson was advocating people not setting off fireworks due to a possible fire hazard. This appears to have what got him killed, although so far there is little solid information.But, sorry, this experiment should not end and not be repeated anywhere else.

I further note that Hannity and others on Fox News are spending lots of time going on and on about this Seattle situation.  Trump has been engaging in a series of increasingly unacceptable and outrageous actions, but those watching Fox and its allies hear and see none of that because, wow, there go those awful rioters in Seattle again!  Initially Fox made up and distorted reporting about what was going on there, which was initially peaceful and, yes,"Summer of Love" like.  But, unfortunately, now they do not need to make up stuff to put up ugly stories about it.

Is The Possible V-Shaped Recovery Flattening As The Second Quarter Comes To An End?

Probably,  although it is unclear whether or not we are having a V-shaped recovery (see most recent post here). However, whatever it is, it looks like the revived spread of the coronavirus is probably slowing it somewhat.  New cases are up by 15% nationally from low point several weeks ago, and there are reports of businesses of various sorts closing, if not whole communities.

The pattern of the increase has various aspects:

1) It seems to be now more in red states than blue states, with the trend having been toward this since the early days of the pandemic when it first started in major Dem cities in major Dem states, such as Seattle, WA, the Bay Area of CA, and the New York metro area.  Of the states with the most rapid recent increase we have only three that are predominantly Dem: CA, OR, and NV, with one purplish, NC, and the rest GOP: SC, GA, FL, AL, MS, AR, OK, TX, AZ, UT.

2) While now it is predominantly rising in GOP states where governors have not strongly encouraged social distancing or mask wearing while rushing to fully reopen, and in some cases even banning local communities from requiring mask wearing in public places, although some of those are now backing off that, such as Abbott in Texas, if one looks at this at the county level it remains that Dem counties are still outnumbering GOP ones, although the trend is strong toward GOP ones, and the line on this one will probably be crossed soon (these designations are based on how they voted in presidential election in 2016). The obvious explanation for this apparent discrepancy is that in the red states cases tend to be increasing more in densely populated areas, which are more likely to be urban areas in Dem counties in those states, such as the Houston metro area in Texas.

3)  There is not a clear pattern of these either being spread across states or concentrated in particular areas.  Some states with increases scattered widely include the Carolinas, Florida, and Alabama.  Some where they are more isolated/concentrated in particular locales include the two largest on this list: California and Texas.

4) Certain sectors seem to be especially hit be reclosings, notably restaurants and bars as well as some sports facilities.

5) A possible offset to all this is that certain communities are still reopening, despite this new round of new cases.  An example is Washington, D.C., which just got going today with its second stage of reopening, following its suburbs in MD and VA that have already done so.

Might There Be A V-Shaped Economic Recovery After All?


This is a matter where if it happens, I shall be proven wrong.  I have mostly emphasized how much uncertainty and lack of knowledge we face about the pandemic as well as the economy in this situation, and have as a result largely stayed away from making specific or definite forecasts on those matters.  However, here and in other places on the internet, I have made a lot of forecasts that the time path of GDP is likely to look like a "lazy J" or "whoosh," a pattern of a slow recovery after the very rapid decline, with a possible W if a second wave of the pandemic hits hard.  What I often dismissed, sometimes rather pompously to people who seemed to push it for blind political or ideological reasons was that there might be a rapid bounceback, a V-shaped recovery.  Now that looks like it might happen, or at least a modest version of it, so I may be wrong on my past forecasts.

Curiously, as noted in a fairly recent post, I was one who was not surprised by the net increase in employment in May, given the evidence noted in still earlier posts of a likely turnaround in GDP that probably dates back even into late April and probably not later than early May, looking at figures on gasoline demand and carbon emissions.  It seemed not surprising that this turnaround would lead to some new hiring, even as further layoffs were clearly happening.  But most of this data seemed consistent with the Whoosh scenario, with these renewed increases occurring at rates much lower than the rates of preceding decline.  So the net increase in hiring in May was only 2.5%, large for a normal time, but only beginning to offset the double digit plunge that had happened before it.

But now we have the report that looks pretty accurate that retail sales rose 17.7% from April to May, not sure  of the precise cutoffs for this.  I made no specific forecast for that, but given the labor hiring numbers, I would figure that probably retail sales rose more than hiring.  But there is no way I would have forecast a double digit increase, and might not even have predicted more than a 5% increase, if I had done so.  Thus, needless to say, I am quite surprised by this figure.

Indeed, for retail sales this more than a V-shaped recovery.  The rate of decline for March to April was -14.4%.  Apparently retail sales are now only 8% below their peak in February.  So the rate of growth of retail sales could slow to half the April to May rate and end up higher than the February level.  I find this hard to believe, but I also have no good grounds for questioning this data.

Advocates of a V-shaped recovery, whether Trump and his immediate advisers, or other economists, mostly a minority, argued that an outburst of "pent-up demand" would lead to this, and it would seem that has happened, with probably some non-trivial assistance from stimulus checks and generous unemployment benefits, along with some other elements of fiscal stimulus, some of which have already stopped or are scheduled to do so in coming months.  I had dismissed such a strong surge of purchasing based on people being afraid and cautious, as well as many sectors still held down specifically due to pandemic restrictions, at least through much of May.

As it is, there have been large sectoral variations in this.  Among the most rapidly rising sectors have been clothing, sports equipment, and furniture.  Would I have forecast these to be tops?  Not particularly.  Others have remained much lower, e.g. cruise lines are still going nowhere.  But lots of sectors have seen pent-up demand bursting out and large sales increases, with retail sales the major part of consumption, which in turn is 70% of GDP.  So this goes a long way to pushing for an overall GDP V-shaped recovery.

But, of course, while it is the largest part of GDP, consumption is not all of it.  And almost certainly the other parts are not rising anywhere near this retail sales rate, with some of them even possibly declining, such as local and  state government activity.  Federal government activity may not be declining, but it is probably not rising that much, as the huge increases in transfer payments are not directly increases in GDP. They only stimulate that through their role in aiding this surge of retail sales that has happened.  While consumers may not have been held back by all the ongoing uncertainty, certainly businesses are, so I would be surprised if we see any increase beyond minimal in capital investment now.  OTOH, there may be some growth in exports as the rest of the world's economy probably turned around sooner than did the US one, and there are reports of some specific exports rising sharply, such as pork exports to China.

There is reason to believe that some of this increase in retail sales will slow down or even reverse, even as some more laggard sectors might pick up.  Several of those most rapidly rising sectors feature big ticket items not likely to be ongoing, especially furniture.  Some of this may have been an outburst of pent-up demand showing up on such big ticket items that will not continue or may even fall back a bit.  But given that I did not catch the scale of this increase at all, I am not really in all that good of a position to make very definite forecasts on all this. 

My bottom line guess on this is that GDP will still not quite look like a perfect (or more rapidly rising on the right-hand side) V, as the non-consumption parts of GDP drag behind and keep the clearly rapidly rising consumption to produce a total GDP rising more rapidly than it fell.  But it is now highly likely that what we shall see in the near future does more resemble a V than any of the other shapes or letters that have been proposed, including those I forecast.
