the move from f to g in Figure (a).

(Exhibit: The Demand for music downloads) A decrease in the price of iPods and other similar devices would result in a change illustrated by:

(Exhibit: The Demand for music downloads) A decrease in the fee charged for music downloads would result in a change illustrated by:

the move from j to k in Figure (c).

The slope and location of the demand curve depend on: A) the number of buyers. B) production costs. C) the number of producers. D) all of the above.

the number of buyers.

A supply curve that is upward sloping means that: A) demand is being ignored. B) consumers will buy less at lower prices. C) suppliers will want to sell more at higher prices. D) suppliers will want to sell less at higher prices.

suppliers will want to sell more at higher prices.

A curve that shows the relationship between the price and quantity supplied during a particular period, all other things unchanged, is the: A) price curve. B) supply curve. C) quantity function. D) production possibilities curve.

supply curve.

In the textbook, the prices of the factors of production, returns from alternative activities, technology, seller expectations regarding future prices, and the number of sellers are called: A) demand shifters. B) supply prices. C) market realities. D) supply shifters.

supply shifters.

When economists study the behavior of sellers, they are studying: A) supply. B) the role of government. C) demand. D) accounting.

supply.

(Exhibit: Demand and Supply of Gasoline) When the supply curve shifted from the initial equilibrium to the new intersection of supply and demand at a price of ________and quantity of 400, this could have resulted from ________. A) $1.50; an increase in consumers' income B) $1.50; an improvement in refining technology C) $2.00; an increase in the number of buyers D) A and B are true

$1.50; an improvement in refining technology

(Exhibit: Demand and Supply of Gasoline) The initial price and quantity (at intersection of S1 and D) in equilibrium are: A) $2.00 and 450 gallons. B) $1.50 and 400 gallons. C) $2.00 and 200 gallons. D) $2.50 and 300 gallons.

$2.50 and 300 gallons.

(Exhibit: Demand and Supply of Gasoline) Given the initial equilibrium of S1 and D,any price lower than _____________ will create pressure for the price to ________. A) $2.00; fall B) $2.50; rise C) $3.00; rise D) none of the above are true

$2.50; rise

(Exhibit: Demand and Supply of Gasoline) What might cause the supply curve to shift from S2 back to the initial supply curve S1? A) The Organization of Petroleum Exporting Countries (OPEC) restricts the production of crude oil. B) The Organization of Petroleum Exporting Countries (OPEC) increases the production of crude oil. C) Americans want to buy more gas. D) Technology in the refinement of gasoline greatly improves.

The Organization of Petroleum Exporting Countries (OPEC) restricts the production of crude oil.

If a demand curve shifts to the left, then: A) the equilibrium price would go up and the equilibrium quantity would go down. B) the equilibrium price would go down and the equilibrium quantity would go up. C) a lower equilibrium price and quantity would result. D) a higher equilibrium price and quantity would result.

a lower equilibrium price and quantity would result.

(Exhibit: Demand and Supply of Gasoline) Given the equilibrium after a change in supply from S1 to S2: A) at the old price of $2.50, there will be pressure for the price to fall. B) the new price will be $2.00. C) the new quantity will be 400. D) all of the above are true.

at the old price of $2.50, there will be pressure for the price to fall.

(Exhibit: Demand and Supply of Gasoline) A factor that may have changed supply from S1 to S2 is: A) better technology in the production of gasoline. B) increased demand. C) lower labor productivity. D) increased prices of substitutes for gasoline.

better technology in the production of gasoline.

A negative relationship between the quantity demanded and price is called the law of______. A) demand B) diminishing marginal returns C) market clearing D) supply

demand.

The relationship between the price of a good and the quantity people are willing and able to purchase is: A) supply. B) demand. C) equilibrium. D) disequilibrium.

demand.
