Cause and effect, it will settle down in week or two and those who overstocked won't be buying more and those who are responsible and now short due to the hoarders of panic are slowly getting back to normal.

But certainly an insight into the culture and humanity of some people. Alas we have a society that seems to always see good responsible people suffer at the hands of the irresponsible.

I believe that the important lesson is that when government steps back, people will resort to ingrained behaviors, and "stock up when a crisis begins" is one of those. The wrong answer to that is to limit the amount anyone can buy, because you're just increasing the crisis-feel. The right answer is to make sure that people calm down, and the easiest way to do that is to demonstrate that the supply of goods is not affected. You do that by adding a fleet of trucks to transport goods to super markets and add a temporary night shift to re-stock shelves. If people see that there is no shortage, they will calm down.

The opposite is happening, you have (local, temporary) shortages and some politician who hasn't bought their own groceries in the last decade says "I assure you, there are no shortages", while everybody sees the empty shelves on a daily basis.

Bit like the ban effect, like many a record seen sales increase down to the aspect that some radio or other avenue deemed to ban the record.

Equally, once many heard news of something was being brought up, the net effect was to drive others into panic and drive them to do the same.

Panic begats panic. So you start to enter into the aspect of https://en.wikipedia.org/wiki/Crowd_psychology

I'm in Hamburg, only spaghetti and hand sanitizer are still sometime missing in my neighborhood. During the past 2 weeks you could see some empty shelves depending on the time of the day, but it seemed to be temporary, due to the rapid increase in demand.

But now that people filled their shelves, I guess that store supplies are back to normal.
