Suppose that the government imposes an excise tax on each unit of production of a product and as a result the supply curve of the product shifts up by the tax amount. For what slopes of demand and supply curves would this shift in supply reduce the equilibrium quantity of the product the most? Group of answer choices Both demand and supply curves are flatter. Demand curve is flatter and supply steeper. Demand curve is steeper and supply flatter. Both demand and supply curves are steeper
