All questions

Question 1

Suppose that smartphones and wireless earbuds are complements. If a major technological innovation lowers the cost of producing smartphones, leading to a lower price for them, what is the resulting effect in the market for wireless earbuds?

  1. A movement down along the demand curve for earbuds.
  2. A rightward shift of the demand curve for earbuds. (correct answer)
  3. A rightward shift of the supply curve for earbuds.
  4. A movement up along the supply curve for earbuds.
Explanation: A lower price for smartphones increases the quantity demanded of smartphones. Since smartphones and wireless earbuds are complements, consumers will want to buy more earbuds to go with their new phones. This increase in consumer desire for earbuds at every price point is represented as a rightward shift of the demand curve for earbuds.

Question 2

A local government reduces property taxes for all businesses in its jurisdiction. For a typical restaurant in this locality, how would this policy change be represented in the market for restaurant meals?

  1. As a rightward shift of the supply curve. (correct answer)
  2. As a rightward shift of the demand curve.
  3. As a movement down along the supply curve.
  4. As a movement down along the demand curve.
Explanation: Property taxes are a cost of doing business for a restaurant. A reduction in these taxes lowers the restaurant's operating costs. With lower costs, the restaurant is willing to offer more meals at any given price. This is represented by a rightward shift of the supply curve.

Question 3

The cost of lumber, a key resource for home construction, decreases. Simultaneously, mortgage interest rates rise, making it more expensive for consumers to borrow money to buy a home. In the market for new single-family homes, what are the respective effects on the supply and demand curves?

  1. Supply shifts right; demand shifts right.
  2. Supply shifts left; demand shifts left.
  3. Supply shifts right; demand shifts left. (correct answer)
  4. Supply shifts left; demand shifts right.
Explanation: The decrease in the cost of lumber, an input, lowers production costs for home builders. This causes the supply curve to shift to the right. The rise in mortgage interest rates increases the total cost of home ownership for buyers, which decreases the demand for homes at any given price. This causes the demand curve to shift to the left.

Question 4

Consider the market for manual-transmission cars. If a new generation of drivers shows a strong preference for automatic-transmission cars, what is the initial result in the manual-transmission car market?

  1. A movement up along the demand curve for manual cars.
  2. A leftward shift in the supply curve for manual cars.
  3. A movement down along the supply curve for manual cars.
  4. A leftward shift in the demand curve for manual cars. (correct answer)
Explanation: The change described is a shift in consumer tastes and preferences, away from manual-transmission cars. A change in tastes is a non-price determinant of demand. This decrease in preference will reduce the number of manual cars consumers are willing to buy at any price, causing the entire demand curve to shift to the left.

Question 5

A report from a consumer advocacy group reveals that a popular brand of orange juice has significantly less vitamin C than advertised. The report is widely covered in the media, leading to a change in the market equilibrium for this brand of juice.

In the market for this specific brand of orange juice, the immediate impact of the report is a change in consumer tastes. How does this event and the subsequent market adjustment affect the supply curve for this orange juice?

  1. The supply curve shifts to the left as producers anticipate lower profits.
  2. The supply curve shifts to the right as producers try to sell off inventory.
  3. There is a movement down along the supply curve to a new, lower equilibrium quantity. (correct answer)
  4. There is no change in the supply curve, but quantity supplied will increase.
Explanation: The negative report shifts the demand curve to the left. This leads to a lower equilibrium price and quantity. The question asks how this affects the supply curve. The supply curve itself does not shift because production costs and technology have not changed. Instead, the fall in price induces producers to offer less for sale, which is represented as a movement down along the existing supply curve.

Question 6

In the labor market for software engineers, an increase in the number of universities offering computer science degrees leads to a larger pool of qualified graduates. This results in a new, lower equilibrium wage. How would this fall in the equilibrium wage be represented on the demand curve for software engineers?

  1. As a rightward shift of the demand curve.
  2. As a leftward shift of the demand curve.
  3. As a movement down along the demand curve. (correct answer)
  4. As a movement up along the demand curve.
Explanation: The larger pool of graduates shifts the supply curve of labor to the right. This leads to a lower equilibrium wage (the 'price' of labor). For employers (the 'demanders' of labor), this lower wage induces them to hire more engineers. This response to a change in the price of labor is a movement down along the existing demand curve for labor, representing an increase in the quantity of labor demanded.

Question 7

Due to a viral social media trend, the popularity of vintage clothing skyrockets. In response to the resulting higher prices, many individuals begin selling clothes from their own closets on online marketplaces. This response by sellers is best described as:

  1. A rightward shift of the supply curve for vintage clothing.
  2. A rightward shift of the demand curve for vintage clothing.
  3. A movement up along the supply curve for vintage clothing. (correct answer)
  4. A movement down along the demand curve for vintage clothing.
Explanation: The initial event is the viral trend, which shifts the demand curve to the right, driving up the equilibrium price. The question asks to describe the response by sellers to these higher prices. As the price increases, more people find it worthwhile to sell their clothes, increasing the quantity supplied. This reaction to a change in price is a movement up along the supply curve.

Question 8

Anticipating that a new trade agreement will significantly lower the price of foreign-made furniture next year, consumers adjust their purchasing behavior this year. This change in expectations will cause which of the following in the current market for domestically-produced furniture?

  1. A movement down along the current demand curve.
  2. A leftward shift of the current demand curve. (correct answer)
  3. A rightward shift of the current supply curve.
  4. A movement up along the current supply curve.
Explanation: Consumer expectations about future prices are a determinant of current demand. If consumers expect prices to be lower in the future, they will decrease their demand today, hoping to buy later at a better price. This decrease in demand at all current price levels is represented by a leftward shift of the current demand curve.

Question 9

Assume beef and chicken are substitutes. A widespread disease affecting cattle leads to a significant decrease in the supply of beef and a higher equilibrium price for beef. How does this increase in the price of beef affect the demand curve for chicken?

  1. It causes a rightward shift of the demand curve for chicken. (correct answer)
  2. It causes a movement up along the demand curve for chicken.
  3. It causes a leftward shift of the demand curve for chicken.
  4. It causes no change in the demand curve for chicken, only a change in price.
Explanation: Since beef and chicken are substitutes, a higher price for beef will cause consumers to buy less beef and more chicken. This increased desire to purchase chicken at any given price is represented by a rightward shift of the demand curve for chicken. A change in the price of a substitute good is a determinant of demand that causes the entire curve to shift.

Question 10

The price of steel, a primary input in automobile manufacturing, rises significantly. In the market for new automobiles, which of the following represents the initial and direct consequence of this event?

  1. A movement up along the supply curve, representing a decrease in quantity supplied.
  2. A leftward shift of the supply curve, representing a decrease in supply. (correct answer)
  3. A leftward shift of the demand curve, representing a decrease in demand.
  4. A movement up along the demand curve, representing a decrease in quantity demanded.
Explanation: An increase in the price of an input (steel) raises production costs for automobiles. This makes producing cars less profitable at any given price, causing producers to supply fewer cars. This is represented by a leftward shift of the entire supply curve. This is a change in supply, not a change in quantity supplied (which would be a movement along the curve caused by a price change of the final good).

Question 11

The government enacts a new per-unit subsidy for producers of solar panels. This policy successfully lowers the market price for consumers. Which of the following describes the effect of this resulting lower price on consumer behavior in the solar panel market?

  1. It causes a rightward shift in the demand curve for solar panels.
  2. It causes a leftward shift in the demand curve for solar panels.
  3. It causes a movement down along the demand curve for solar panels. (correct answer)
  4. It causes a movement up along the demand curve for solar panels.
Explanation: The subsidy shifts the supply curve to the right, which leads to a lower equilibrium price. The question asks for the effect of this lower price on consumer behavior. A change in the good's own price causes a change in the quantity demanded, which is represented as a movement along the demand curve. Specifically, a lower price leads to a movement down along the curve to a higher quantity demanded.

Question 12

A widely publicized medical study concludes that consumption of avocados provides significant long-term health benefits. As a result, the equilibrium price of avocados increases. Which statement correctly describes the consequences of this price increase in the market for avocados?

  1. The increase in price causes the demand curve for avocados to shift to the right.
  2. The increase in price causes the supply curve for avocados to shift to the right.
  3. The increase in price causes an upward movement along the supply curve for avocados. (correct answer)
  4. The increase in price causes a downward movement along the demand curve for avocados.
Explanation: The initial event (the medical study) causes the demand curve to shift right. This new demand curve intersects the existing supply curve at a higher equilibrium price. This higher price incentivizes producers to offer more for sale, which is represented as an upward movement along the existing supply curve to the new equilibrium quantity. The price change itself does not shift either curve.

Question 13

A period of nationwide economic recession leads to a significant decrease in average household income. In the market for generic, store-brand canned soup, which is widely considered an inferior good, what is the initial impact?

  1. The supply curve for generic soup shifts to the left.
  2. The demand curve for generic soup shifts to the right. (correct answer)
  3. There is a movement down along the demand curve for generic soup.
  4. There is a movement up along the supply curve for generic soup.
Explanation: An inferior good is a good for which demand increases as income decreases. Since the recession lowers average income, consumers will substitute away from more expensive options and toward cheaper alternatives like generic soup. This increase in demand at all price levels is represented by a rightward shift of the demand curve.

Question 14

A new, more efficient harvesting technology for coffee beans is adopted by most growers. This innovation leads to a change in the equilibrium price and quantity of coffee. How does this technological advance affect the demand curve for coffee?

  1. It causes the demand curve to shift to the right, as coffee is now cheaper.
  2. It causes a movement down along the demand curve to a higher quantity demanded. (correct answer)
  3. It causes the demand curve to shift to the left, as the market becomes saturated.
  4. It causes a movement up along the demand curve to a lower quantity demanded.
Explanation: The new technology shifts the supply curve to the right, leading to a lower equilibrium price. This decrease in the price of coffee results in an increase in the quantity demanded, which is shown as a movement down along the unchanged demand curve. The technology itself does not change consumer preferences or income, so the demand curve does not shift.

Question 15

A government agency, seeking to curb sugar consumption, places a binding price floor on sugary soft drinks, setting it above the current equilibrium price. This action by itself, before any further market adjustments, directly causes:

  1. A decrease in quantity demanded and an increase in quantity supplied. (correct answer)
  2. A leftward demand shift and a rightward supply shift.
  3. An increase in demand and a decrease in supply.
  4. A decrease in quantity demanded and a leftward supply shift.
Explanation: A price floor set above equilibrium forces the market price up. This price change does not shift the curves themselves. Instead, it causes movements along the existing curves. For consumers, the higher price causes a decrease in quantity demanded (a movement up the demand curve). For producers, the higher price causes an increase in quantity supplied (a movement up the supply curve). This leads to a surplus.

Question 16

If a firm observes that the price of its product has increased, leading it to increase its production output, what economic concept does this action illustrate?

  1. A change in supply, resulting in a shift of the supply curve.
  2. A change in quantity demanded, resulting in a movement along the demand curve.
  3. A change in demand, resulting in a shift of the demand curve.
  4. A change in quantity supplied, resulting in a movement along the supply curve. (correct answer)
Explanation: The scenario describes a firm's reaction to a change in the market price of its own product. An increase in price incentivizes the firm to produce more. This relationship between the price and the amount a firm is willing to sell is captured by the supply curve. The change is therefore a change in the quantity supplied, represented by a movement along the supply curve.

Question 17

After a successful advertising campaign, a company raises the price of its flagship product. The subsequent decrease in sales is observed. This decrease in sales should be characterized as:

  1. A decrease in demand caused by the price increase.
  2. A decrease in quantity supplied in response to lower sales.
  3. A leftward shift in the demand curve due to market saturation.
  4. A decrease in quantity demanded caused by the price increase. (correct answer)
Explanation: The question describes two events. The successful ad campaign would first shift demand to the right. Then, the company raises its price. The question asks to characterize the decrease in sales after the price increase. A change in sales resulting from a change in the product's own price is a change in quantity demanded, not a change in demand. The higher price causes a movement up along the new, shifted demand curve.

Question 18

If the market price of a product increases, and this change in price is the only event occurring in the market, which of the following must be true, holding all else constant (ceteris paribus)?

  1. The demand for the product has increased, and the supply has decreased.
  2. The quantity demanded of the product decreases, and the quantity supplied increases. (correct answer)
  3. The demand curve shifts left, and the supply curve shifts right.
  4. The quantity demanded and the quantity supplied of the product both decrease.
Explanation: This question tests the fundamental definitions of movements along curves. Ceteris paribus, an increase in a product's own price causes consumers to buy less (a decrease in quantity demanded, a movement up along the demand curve) and producers to offer more for sale (an increase in quantity supplied, a movement up along the supply curve).

Question 19

In the market for corn, an unusually favorable growing season leads to a record-high harvest across the country. This event would be graphically represented as a  , leading to a  .

  1. rightward shift of the supply curve; movement down along the demand curve (correct answer)
  2. movement down along the supply curve; rightward shift of the demand curve
  3. rightward shift of the demand curve; movement up along the supply curve
  4. leftward shift of the supply curve; movement up along the demand curve
Explanation: A favorable growing season is a positive supply shock. It means more corn can be produced at any given price, which is represented as a rightward shift of the supply curve. This increase in supply leads to a lower equilibrium price. The decrease in price, in turn, causes an increase in the quantity demanded, which is represented as a movement down along the existing demand curve to the new equilibrium point.

Question 20

Which of the following scenarios would most likely cause a movement along the demand curve for movie tickets, rather than a shift in the demand curve?

  1. A major streaming service, a substitute for movie theaters, raises its monthly subscription fee.
  2. A widely acclaimed blockbuster film is released, increasing the popularity of going to the movies.
  3. Movie theaters offer a 'half-price Tuesday' promotion, reducing ticket prices for that day. (correct answer)
  4. The average household income in the economy increases, and movie tickets are a normal good.
Explanation: A movement along the demand curve is caused by a change in the price of the good itself. The 'half-price Tuesday' promotion is a direct change in the price of movie tickets, which would cause an increase in the quantity demanded (a movement along the curve). The other options describe changes in the price of a substitute (A), consumer tastes (B), and income (D), all of which would cause the entire demand curve to shift.
