The intention of a price floor is to help producers by setting a higher than equilibrium price. What is one unintended consequence of this policy

One unitended consequence of this policy is that if the price is above the equilibrium price then this will affect the market by producing black market, low importance to the product that has risen up in price and more importantly it will produce the demand of the product to fall down.

Explanation:

To begin with, the price floor is a method used in the microeconomics theory in order to give help to the producers from the government who are the ones who choose how to control and manipulate the price of the good. But this method tends to be very aggressive and not good at all if the price floor is set above the equilibrium price set by the market itself and that is because the producers will be offering a product that is much expensive in price and not worth in value at all so the demand for the product will fall and it will create a black market where the consumers who want to pay less will go there for even a product with less quality.
