Supply shortages mean that the quantity demanded is more than the quantity supplied. When one or more factors of production are in short supply we run into several issues:
1: The item being produced will increase in price due to a decrease in products.
2: There will be a limited number of items being produced.
3: Demand could increase rapidly if people fear the item may be kept in short supply for a while (We saw this with masks and hand sanitizer during the pandemic)
4: Theft of that item may increase if scarcity reaches its breaking point.
I hope this helps! :)
