QUESTION 20 Suppose that the demand for Cracker Jacks increases from 400 to 425 boxes when the price falls from $1.50 to $1.25. In this situation you would say that the demand is: • Inelastic Unitary elastic Economic elastic Elastic QUESTION 21 To increase revenue with an inelastic product, a firm will most likely increase the price. True False QUESTION 22 If a price ceiling is set above the market equilibrium price: Prices will rise to the ceiling price Nothing will happen. Nobody is charging that price A shortage in the market will occur A price floor will have to be set below equilibrium QUESTION 23 If a product is almost purely inelastic and the government places an excise tax on the product: Nothing will occur. Elasticity has no effect on taxes The seller will absorb most of the tax The tax will be divided about equally between the seller and buyer The tax will mostly be borne by the customer QUESTION 24 As we move leftward along a straight-line demand curve, the (absolute value of the) price elasticity of demand A grows smaller B. remains constant at zero C. remains constant at a value of one D. remains constant and equal to the (absolute value of the) slope of the demand curve E. grows larger QUESTION 25 An example of a price control is: Black market strategy Rent control Price efficiency Elasticity 4 points Saved 4 points Saved 4 points Saved 4 points Saved 4 points ?
