Due to the virus outbreak, there is a surge in demand for mask and hand sanitizes. To prevent price hiking government impose a price ceiling on the products, however consumers are behaving irrational (I.e. mask hoarding and overbuying) then they impose a supply restriction on the market.
Isn't this causes the market to be very inefficient, because the dead weight loss is extended to the left or this lets the government buys up some masks for their own stock to cover the DWL? Do you think is there any other reason why government decides to implement this?
