Invisible hand is a phrase given by Adam Smith. It is a free market economy, meaning the supply and demand of an economy has been determined freely by the market forces. No intervention of the government has taken place in it.

how do you think covid affected the working of the invisible hand either negatively or positively? Such as how toilet paper was out of stores for a while/ small stock, and eggs were so popular that the store I work at put limits on how much one person could buy.
