  • Since the turn of this century in 2000, and excepting the latest six months of slower activity due to COVID-19 shutdowns, China has managed exceptional year-over-year gross domestic product growth (i.e., of +6% recently, but +10% or more earlier) due, in large part, to a string of major infrastructure spending programs. To make up for the nation’s Q1 2020 downturn in output, the government in Beijing is launching another wave of massive public investment. This time, though, the trillions of yuan will go into other areas of the economy. Instead of road, bridge, railway, train station, rapid transit and airport projects, the emphasis will be on securing China’s lead in such hot-prospect and high-tech sectors as telecommunications and biotechnology.
  • In the past, when China embarked on an infrastructure building binge, the huge increase in demand for raw materials necessitated sourcing from multiple resource sites around the world, with extraction firms in Australia, Canada, South America and Africa all benefitting. Commodity prices soared and the owners of raw materials had a field day. A commonly quoted statistic is that nearly 50% of base metals, fossil fuels, steel and aluminum consumption worldwide has been in the People’s Republic. If there is to be an emphasis on different kinds of infrastructure works this time, though, the impacts for resource producers will be harder to assess, until the specs appear.

  • The degree to which the coronavirus vaccine development process is being compressed (i.e., from ten years or more to one year or less) raises an abundance of ethical issues. Human volunteers for clinical trials are being exposed to unknown dangers and side effects.
  • The least questionable trial methodology ‒ assuming such a thing can be placed on a sliding scale ‒ monitors the results when inoculated subjects simply continue to live, as per usual, among a general population that’s been infected. If, however, there is positive progress in lowering the infection rate of the population at large by non-vaccine means, it will make it harder to obtain reliable results from the test group. Ironic, right? Therefore, the test group may need to be chosen from a location where the coronavirus infection rate is still climbing or near its peak.

  • Concerning COVID-19, possibly the best to be hoped for over the next many months will be the emergence of ‘herd immunity’. ‘Herd immunity’ will occur when approximately two-thirds of the population has been in contact with the coronavirus, creating enough antibody protection to severely slow its spread. Nevertheless, that will still leave one-third living under the sword of Damocles. Randomly, someday, somewhere, somehow, they may be touched by COVID-19 with possibly dire consequences. At least, that will be case until an effective vaccine has been created.
  • This is where the science becomes fascinating, but also complicated. Apparently, there may be development of several different makes and models of COVID-19 vaccine. A standard vaccine uses a weakened version of the offending virus to prod a body into launching an overwhelming defense posture. A new ‘platform’ approach, with a shorter testing and approvals span, modifies a known closely related virus ‒ maybe even from the animal kingdom, since there are untold numbers of viruses with an incredible diversity of characteristics ‒ to become a harmless copycat of the latest interloper, in order to engage the body’s immune system and set in place a rapid deployment system to fight off future attacks.

  • Sporting events are coming out of hibernation. NASCAR drivers will be pushing pedals to the metal at Darlington Raceway, South Carolina, on Sunday May 17th. Racing teams and officials will be required to practice safe distancing and no fans will be allowed in the stands. The event will be broadcast live on TV and satellite radio.
  • Seven days later, on the 24th, the famed Coca-Cola 600 NASCAR race (again with no live audience) will be held, as it has been for 60 years, during the Memorial Day weekend. The Indianapolis 500 IndyCar race, though, with 200 laps over a two-and-a-half-mile track in Speedway, Indiana, has been moved to Sunday, August 23rd.

  • Pivot time, everyone! No longer is all the news surrounding the health care crisis entirely about bringing the economy to a near standstill so that ‘social distancing’ can establish fire walls against the spread of the coronavirus. More than half of U.S. states are presently allowing some form of business re-openings.
  • New guidelines, ‒ to be implemented in phases, ‒ for conducting operations in restaurants, retail stores, cinemas and so on vary widely by location, but they all include some version of personal protective gear and reduced space occupancy.
    • Shopping mall giant Simon Properties is promising to hand out free masks to patrons upon entry into one of its properties.
    • Also, with respect to face coverings, JetBlue has become the first major airline to require their use by all flight attendants and passengers on the company’s jets.
    • Where cinema screenings will be allowed once again, attendance under Phase One rule relaxations will be limited to 20% of capacity.
    • The at-most ‘repopulation’ aim for many retail outlets is five customers per 1,000 square feet.
    • Desks in schools will be set at least six feet apart. Students will eat their lunches in classrooms. Congregating in cafeterias and gyms will be forbidden.

  • When ‘testing’ is mentioned concerning the coronavirus, it’s important to know that there are two kinds. There’s diagnostic testing, which inserts a thin swab deep into the nasal sinus cavity, to determine if someone is currently in the grip of the virus. Then there’s a blood sample test to establish if one has built up immunity based on a storehouse of immunoglobulins. (There are two ‘makes’ of antibodies, a first-attack kind and a second wait-in-the wings-in-case-the-devil-returns kind.) The more people there are with antibodies, the bigger the potential labor pool to restart the economy. By the way, how long the effectiveness of the second more-crucial type of antibody lasts is still unknown.
  • If you check the Uber app on your phone, you’ll probably find there are still a few drivers willing to take you somewhere, to do something … maybe to a workplace judged ‘essential’, or to a medical appointment, or to buy groceries. Depending on which states and/or provinces re-open soonest, they may also be able to motor you to a bowling alley, bingo parlor or tattoo artist.

  • Some in the construction industry have been pinning their hopes for revival on an infrastructure spending package. Let’s look at the financing situation. The U.S. fiscal deficit this year is approaching $4 trillion, with three-quarters of that amount being rescue money. The priority order of relief expenditures has been: income supplements; unemployment insurance top-ups; help for large- and medium-sized corporations; specific industrial sector support (e.g., airlines); aid for urban transit systems and for hospitals; and a first round of small business loans, followed by a larger second round.
  • Not even covered yet are state and local government shortfalls caused by tax revenue swan dives. So, will another trillion dollars be set aside for infrastructure spending? There’s always the possibility that a political-gain motivation, seen by one party or the other, may prevail. But with a new debt mountain looming, it seems unlikely to me.

  • Canadians have entered the pandemic unprepared. In total, they have a record high level of household debt to disposable income, a ratio exceeding 170%. The reason for the debt buildup has been an exceptionally strong residential real estate market.
  • For years, speculation concerning a runaway housing bubble in Canada has been noted but, for the most part, brushed aside … although it is worth mentioning that there have been some government-imposed steps to cool overheating home prices. Nevertheless, the roosters have finally come home to cock-a-doodle-doo, but in an unexpected way.

  • OxBlue is a company that sells live-feed cameras for construction sites, to monitor worker movements and equipment flows, to guard against theft, and to record daily progress for contractors and owners ‒ sometimes letting the public in on the spectacle as well, by means of an Internet link ‒ as structures take shape.
  • With the onset of the coronavirus crisis, many construction projects are being shunted onto sidetracks. Based on algorithms tied to what its cameras are seeing, OxBlue has calculated an index of ongoing construction activity levels across America. Presently, according to OxBlue, the six states with the sharpest declines in onsite work are: Pennsylvania, Michigan, Massachusetts, Washington, New York and Ohio.

  • The website ‘flightradar24.com’ (dashboard heading ‘Statistics’) records that the number of commercial flights globally (as a 7-day moving average) on March 12, 2020, was 101,297. From mid-March on, there was a rapid falling off, so that by April 12 (one month later), the figure had descended to just 29,442, a giant-sized drop of -71%. (‘Commercial’ flights are defined as passenger, cargo, charter and some business-jet flights. Excluded are glider, helicopter, ambulance and some military excursions.)
  • Latest month-to-month airport departure statistics (number of actual flights) from ‘flightradar24.com’ show the following: Dallas-Ft. Worth International Airport, -59%; Chicago O’Hare, -66%; Atlanta Hartsfield Jackson, -69%; Los Angeles International Airport, -72%; New York John F. Kennedy, -81%; Montreal’s Pierre Elliott Trudeau Airport, -82%; Toronto’s Pearson International, -83%; and N.Y.’s LaGuardia, -92%.
