Tell whether each of the following statements is true or false. If a statement is false, explain why.
1. A tax that takes $100 from every household in the country is a proportional tax.
2.A perfectly inelastic demand curve is a vertical line.
3.An increase in the price of Pepsi causes an increase in the demand for Coca-Cola, rather than an increase in the quantity of Coca-Cola demanded.
4.If the quantity demanded equals eight minus the price and the price is 2, the amount of Consumer Surplus is 12.
5.If the cross-price elasticity of demand between two items is positive, the two items are substitutes.
6.If an item is extremely insignificant in your budget, your demand for the item is likely to be very inelastic.
7.If the quantity demanded is 6 units per week at a price of $3 per unit and 10 units per week at a price of $2 per unit, the demand between the two points on the demand curve is elastic.
8.If the makers of Coca-Cola develop a process to bottle more bottles per hour without any increase in labor or in any other input, the demand curve for Coca-Cola shifts to the right.
9.If both Brazil and the United States have straight-line production-possibilities curves, the U.S. can use all its resources to produce either 10 tons of coffee or 10 tons of wheat per year, and Brazil can use all of its resources to produce either 4 tons of coffee or 2 tons of wheat per year, Brazil has a comparative advantage in coffee production.
10.If the quantity demanded equals 10 minus the price and the quantity supplied equals four times the price, there is more Consumer Surplus at the equilibrium price than there would be if the Government set a price ceiling of $1.
