price floors

floors where a company must charge a minimum price for a good at least. they could go over but must meet the requirement. a few things on the floors in europe is agriculture products like butter, grains ect. in hopes the price stays in a balance they buy stock of it to protect the economy and the product, so that it allows for more to be supplied next harvest. but the higher prices cause a lot of surplus in the hands of the government not the producer.
