CHAPTER The two words most often used by economists are a prices and quantities b resources and allocation c supply and demand d efficiency and equity In a market economy, supply and demand are important because they a play a critical role in the allocation of the economy’s scarce resources b determine how much of each good gets produced c can be used to predict the impact on the economy of various events and policies d All of the above are correct Which of the following statements is correct? a Buyers determine supply and sellers determine demand b Buyers determine demand and sellers determine supply c Buyers determine both demand and supply d Sellers determine both demand and supply The demand for a good or service is determined by a those who buy the good or service b the government c those who sell the good or service d both those who buy and those who sell the good or service The law of demand states that, other things equal, a an increase in price causes quantity demanded to increase b an increase in price causes quantity demanded to decrease c an increase in quantity demanded causes price to increase d an increase in quantity demanded causes price to decrease The supply of a good or service is determined by a those who buy the good or service b the government c those who sell the good or service d both those who buy and those who sell the good or service A demand schedule is a table that shows the relationship between a quantity demanded and quantity supplied b income and quantity demanded c price and quantity demanded d price and income The demand curve for a good is a a line that relates price and quantity demanded b a line that relates income and quantity demanded c a line that relates quantity demanded and quantity supplied d a line that relates price and income The sum of all the individual demand curves for a product is called a total demand b consumer demand c aggregate demand d market demand The law of supply states that, other things equal, a an increase in price causes quantity supplied to increase b an increase in price causes quantity supplied to decrease c an increase in quantity supplied causes price to increase d an increase in quantity supplied causes price to decrease The supply curve for a good is a a line that relates profit and quantity supplied b a line that relates input prices and quantity supplied c a line that relates price and quantity supplied d a line that relates price and profit The sum of all the individual supply curves for a product is called a total supply b market supply c aggregate supply d total output The dictionary defines equilibrium as a situation in which forces a are in balance b are the same c clash d remain constant When the price of a good is higher than the equilibrium price, a a shortage will exist b buyers desire to purchase more than is produced c sellers desire to produce and sell more than buyers wish to purchase d quantity demanded exceeds quantity supplied Which of the following would cause price to decrease? a a decrease in supply b an increase in demand c a surplus of the good d a shortage of the good When the price of a good is lower than

from its current level c the current price is below its equilibrium price d quantity supplied exceeds quantity demanded Suppose roses are currently selling for $40 per dozen, but the equilibrium price of roses is $30 per dozen We would expect a a shortage to exist and the market price of roses to increase b shortage to exist and the market price of roses to decrease c surplus to exist and the market price of roses to increase d surplus to exist and the market price of roses to decrease An increase in supply is represented by a a movement downward and to the left along a supply curve b a

the a time horizon b income of consumers c price elasticity of demand d importance of the good in a consumer’s budget A key determinant of the price elasticity of supply is a the ability of sellers to change the price of the good they produce b the ability of sellers to change the amount of the good they produce c how responsive buyers are to changes in sellers' prices d the slope of the demand curve The price elasticity of supply measures how much a the quantity supplied responds to changes in input prices b the quantity supplied responds to changes in the price of the good c the price of

will shift up c will shift down d will become flatter If a tax is levied on the buyers of a product, then the demand curve a b c d will not shift will shift down will shift up will become flatter A tax on the buyers of TV: a leads sellers to supply a smaller quantity at every price b leads buyers to demand a smaller quantity at every price c leads buyers to demand a larger quantity at every

is preferred to all other points identified in the figure c Since more is preferred to less, bundle C may be preferred to bundle E in some circumstances for this consumer d Even though bundle E has more of both goods than bundle B, we could draw a different set of indifference curves in which bundle B is preferred to bundle E Refer to Figure 21-7 Which of the following statements is not true for
