Covid-19 Impact on Employment: No Impact, Work at Home, or Laid Off (A Statistical Analysis)


Covid-19 Impact on Employment: No Impact, Work at Home, or Laid Off (A Statistical Analysis)

The Covid-19 pandemic and the related lockdown  had a significant effect on employment in many countries around the world.  It is natural to wonder which types of jobs were most affected and in what way?

As it turns out, the June 3, 2020 Globe and Mail Report on Business had a story on this (page B5).  Their main focus was on the relationship between the ability to work from home (Telework Capacity) and the Employment Change in Canada between February and April, 2020.  This was plotted for a number of major industry/employment types.  Though it uses Canadian data, it seems likely that these results would prove true for other advanced economies.



I have reproduced the graph in that story above, adding the R-square and regression relationship to the graph.  I also added an indicator colour and number for each point on the graph, that shows the urgency of the task under consideration being carried on, regardless of the pandemic (i.e. how big an impact would a short-term disruption in this industry/job type have on society?). 

The indicator is somewhat subjective (my own determination), though I think it would align fairly well with the notion of primary production, secondary production and service industry.  A red dot is a highly necessary activity (also coded 1), while a blue dot is a less urgent activity (also coded 0).

As you can see, there is a relationship between employment change (always negative during this time) and Telework Capacity (the sloped line).  Basically, if an industry/job type had the necessary communications capacity, the employment loss was substantially reduced.

The other phenomenon visible in the graph is that the red dots tend to be higher on the graph than the blue dots.  In other words, jobs that could be considered highly necessary (such as utilities, agriculture and health) had lower employment loss than those that were less urgently needed (such as accommodation/food and arts/recreation).  This isn’t to say that the latter jobs aren’t necessary or useful, just that society can mostly get along without them for a while. 

That difference in job loss is shown in the graph below.  Also shown, is the finding that Telework Capacity didn’t differ overall by these two main job categories.




A bivariate regression of the Telework-Job Loss relationship gives an R-square of .24 and an adjusted R-square of .18 (using the Excel Data Manager Add-in).  A bivariate regression of the Job Necessity – Job Loss relationship has an R-square of .21 and an adjusted R-square of .15.  Both of these models are not quite at the standard statistical significance level of p=.05 (p=.06 and p=.07 respectively.

A multivariate model, using both variables has an improved R-square, of .46, and an adjusted R-square of .37.  The enhanced model has a statistical significance of p=.019, so considering both variables effect together on employment levels is a substantially better model than using either variable alone.  The mathematical/statistical details of the model are shown below.


To sum up:
·       The Covid-19 lockdown reduced employment overall and in all job categories.
·       The impact was less for jobs that could easily be worked from home.
·       The impact was less for jobs that were necessary on a day-to-day basis (e.g. health and utilities) than they were on jobs that were less urgently needed (e.g. restaurants and art galleries).
·       If a job was not exactly essential, but could be done from home, employment was not much affected (e.g. Finance and Insurance).
·       If a job was essential, and couldn’t be done from home (via telework), employment was not much affected anyway (agriculture/forestry).
Fortunately, there was government assistance for workers in many of these jobs that couldn’t be done from home and weren’t deemed to be essential (such as restaurants).

And, here’s are some more pleasant work and travel stories than anticipating the worldwide journey of a virus.

A Drive Across Newfoundland


Newfoundland, Canada’s most easterly province, is a region that is both fascinating in its unique culture and amazing in its vistas of stark beauty. The weather is often wild, with coastal regions known for steep cliffs and crashing waves (though tranquil beaches exist too). The inland areas are primarily Precambrian shield, dominated by forests, rivers, rock formations, and abundant wildlife. The province also features some of the Earth’s most remarkable geology, notably The Tablelands, where the mantle rocks of the Earth’s interior have been exposed at the surface, permitting one to explore an almost alien landscape, an opportunity available on only a few scattered regions of the planet.
The city of St. John’s is one of Canada’s most unique urban areas, with a population that maintains many old traditions and cultural aspects of the British Isles. That’s true of the rest of the province, as well, where the people are friendly and inclined to chat amiably with visitors. Plus, they talk with amusing accents and party hard, so what’s not to like?

This account focusses on a two-week road trip in October 2007, from St. John’s in the southeast, to L’Anse aux Meadows in the far northwest, the only known Viking settlement in North America. It also features a day hike visit to The Tablelands, a remarkable and majestic geological feature. Even those who don’t normally consider themselves very interested in geology will find themselves awe-struck by these other-worldly landscapes.

On the Road with Bronco Billy

Spring is on us now, and that brings on thoughts of ROAD TRIP.  Sure, it is still a bit early, but you can still start making plans for your next road trip with help of “On the Road with Bronco Billy”.  Sit back and go on a ten day trucking trip in a big rig, through western North America, from Alberta to Texas, and back again.  Explore the countryside, learn some trucking lingo, and observe the shifting cultural norms across this great continent.  Then, come spring, try it out for yourself.
