Countries are already making their own approach to this pandemic albeit the continuous warnings of the WHO to a possible second wave of the disease since they couldn't afford any more quarantines or lock downs. While the teachings of the 1918 pandemic re: social distancing and quarantines somewhat helped in slowing the disease, it also served as a hurting edge by aiding with the mass layoffs that's happening on every part of the world. As we know more on the nature of the virus, which population is vulnerable and which aren't, governments are preparing for the 'worst' that is to come since we can no longer afford losing money and risk a larger economic meltdown. Guidelines are already published on the slow but gradual return to the supply chains and other sectors of the economy while schools and academe are still barred operating and holding classes face-to-face.
At least though, this pandemic brought some interesting thoughts on the table. Cities with dense populations are no-go zones in the future that's for sure due to the fear of yet another viral outbreak, and dispersing the number of workers all throughout the country and promoting more growth on the rural areas. This might also mean that dying enterprises and industries might soon be revived due to the lack of work available currently. All in all this pandemic might help us redo the system and revisit the 'lost' parts of our society that has been long centered on cities with bustling activity and roaring skyscrapers.
Asides natural resources, like oil and gold which nations possess inherently, other resources can be integrated in; Machine parts, food resources, etc. This could lead to greater internal investments on skills; and could increase employment, this would have more impact on nations with trade deficit. Although this would still have to be done in consideration of the Heckscher-Ohlin Model; which encourages nations to produce that which utilizes their abundant resources, but a heavy dependence on imports have allowed nations overlook possibilities that can be harnessed and maximized.
Since no money is circulating on most countries currently, I believe that the Heckscher-Ohlin model would be observed and followed greatly in order to complement one country's needs to the other, making an equilateral trade without loss nor profit but just enough to sustain economies in the meantime. Harmony in trade relations is what's really needed with the current situation of our global economy. While the H-O model gives a somewhat good light of hope on countries with specific abundance in natural resources, certain countries in the Middle East would have to make do with what they have since their oil isn't as valuable as it was before all of this, making them reliant on their cash reserves to make some imports on what they really need.
Side note: Do you also think this would have an effect on an individual level? Services such as in-house painting, furniture moving, plumbing work, food delivery etc from outside sources, the fear of contracting a virus could lead more people to take a more Do It Yourself approach and what impact would this have on home delivered services?
You can call this the DIY era IMO since people can't go out and certain people with limited access can roam around for specific purposes, and as such leaves the task on their own hands. Laborious tasks such as what you've mentioned require the worker to touch surfaces of the different parts of the house, so there's the threat of the virus being spread here and there. But with careful application of aseptic techniques to make sure the workplace is clean and free of virus, in-house services shouldn't be a problem.
But yeah, I'm seeing myself learning some stuff that I previously didn't care to bother about since I have some people to do it for me. Just the other day, I was able to make my own study table (definitely not ordered from IKEA) since I can't see a reliable appliance/hardware store that can ship me one immediately.
