8. Use supply and demand curves to depict equilibrium price and output in a competitive market for some farm product. Then show how an above-equilibrium price floor

(a) changes supply or

(b) changes demand. Identify each of the following actual government policies as primarily affecting the supply of or the demand for a particular farm product: crop restriction, government buyout of dairy herds, export promotion.
