Questions and Answers
  • 1. 

    Point at which quantity demanded equals the same amount as quantity supplied is called:

    • A.

      Price ceiling

    • B.

      Shortage

    • C.

      Equilibrium

    • D.

      Disequilibrium

    • E.

      Price floor

    • F.

      Surplus

    Correct Answer
    C. Equilibrium
    Explanation
    Equilibrium is the point at which the quantity demanded by consumers is equal to the quantity supplied by producers. It represents a state of balance in the market, where there is no shortage or surplus of goods. At equilibrium, the price is set at a level that both buyers and sellers agree on, ensuring that the market clears and there is no excess demand or supply.

    Rate this question:

  • 2. 

    When quantity supplied does not equal quantity demanded the market is what?

    • A.

      Price ceiling

    • B.

      Shortage

    • C.

      Equilibrium

    • D.

      Disequilibrium

    • E.

      Surplus

    Correct Answer
    D. Disequilibrium
    Explanation
    When quantity supplied does not equal quantity demanded, it indicates a state of disequilibrium in the market. This means that there is either a shortage or a surplus of the product. In the case of a shortage, the quantity demanded exceeds the quantity supplied, leading to an imbalance in the market. On the other hand, a surplus occurs when the quantity supplied exceeds the quantity demanded. In both cases, the market is in a state of disequilibrium as the forces of supply and demand are not balanced.

    Rate this question:

  • 3. 

    When quantity demanded is more than quantity supplied

    • A.

      Price ceiling

    • B.

      Shortage

    • C.

      Equilibrium

    • D.

      Price floor

    • E.

      Surplus

    Correct Answer
    B. Shortage
    Explanation
    When the quantity demanded is more than the quantity supplied, it creates a shortage. This means that there is not enough supply to meet the demand, resulting in a situation where consumers are unable to purchase as much of the product as they would like. This imbalance in supply and demand can lead to higher prices and competition among consumers to obtain the limited supply available.

    Rate this question:

  • 4. 

    The maximum price that can be charged legally for a good is called

    • A.

      Price ceiling

    • B.

      Shortage

    • C.

      Disequilibrium

    • D.

      Price floor

    • E.

      Minimum wage

    Correct Answer
    A. Price ceiling
    Explanation
    A price ceiling is a government-imposed limit on the maximum price that can be charged for a good or service. It is usually set below the equilibrium price in order to protect consumers and ensure affordability. By preventing prices from rising too high, a price ceiling can help to alleviate potential market failures and promote fairness in the distribution of goods. In this context, the correct answer is price ceiling.

    Rate this question:

  • 5. 

    The government set price floor on the earnings for workers is called:

    • A.

      Price ceiling

    • B.

      Shortage

    • C.

      Disequilibrium

    • D.

      Price floor

    • E.

      Minimum wage

    • F.

      Rent control

    Correct Answer
    E. Minimum wage
    Explanation
    The correct answer is minimum wage. The government sets a price floor on the earnings for workers through the establishment of a minimum wage. This minimum wage ensures that workers are paid a certain amount, which is typically higher than the market equilibrium wage. By setting a minimum wage, the government aims to protect workers from exploitation and ensure that they receive a fair and livable wage.

  • 6. 

    The amount of a product that cannot be sold at a given price is called

    • A.

      Price ceiling

    • B.

      Shortage

    • C.

      Equilibrium

    • D.

      Disequilibrium

      Price floor

    • F.

      Minimum wage

    • G.

      Rent control

    • H.

      Surplus

    Correct Answer
    H. Surplus
    Explanation
    A surplus refers to the amount of a product that cannot be sold at a given price. It occurs when the quantity supplied exceeds the quantity demanded in the market. This means that there is an excess supply of the product, which leads to a surplus. In this situation, sellers may need to lower the price in order to sell the excess inventory.

    Rate this question:

  • 7. 

    When price is set above equilibrium this will result in: 

    • A.

      Price ceiling

    • B.

      Shortage

    • C.

      Equilibrium

    • D.

      Price floor

    • E.

      Surplus

    Correct Answer
    E. Surplus
    Explanation
    When the price is set above equilibrium, it means that the price is artificially higher than what the market would naturally determine. This leads to a surplus, as the quantity supplied by producers exceeds the quantity demanded by consumers at that higher price. In other words, there is an excess supply of the product, which can result in unsold goods or inventory buildup.

    Rate this question:

  • 8. 

    A price below a product's equilibrium price will result in a shortage of the product

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    When the price of a product is set below its equilibrium price, it means that the price is lower than what the market demands. This creates an imbalance between the quantity demanded by consumers and the quantity supplied by producers. As a result, there will be more consumers willing to buy the product at the lower price than there are products available. This leads to a shortage of the product, as the demand exceeds the supply. Therefore, the statement that a price below a product's equilibrium price will result in a shortage is true.

    Rate this question:

  • 9. 

    A market is always in a state of equilibrium. 

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    A market is not always in a state of equilibrium. Equilibrium in a market occurs when the quantity demanded by consumers is equal to the quantity supplied by producers. However, markets are dynamic and constantly changing due to various factors such as changes in consumer preferences, technology, and government policies. These changes can disrupt the balance between supply and demand, leading to shifts in prices and quantities, and causing the market to be in a state of disequilibrium. Therefore, the statement that a market is always in a state of equilibrium is false.

    Rate this question:

  • 10. 

    Given an upward slopping supply curve, a rightward shift of the demand curve

    • A.

      Decreases both equilibrium price and quantity

    • B.

      Increases both equilibrium price and quantity

    • C.

      Decreases equilibrium price only

    • D.

      Increases equilibrium price only

    Correct Answer
    B. Increases both equilibrium price and quantity
    Explanation
    When the demand curve shifts to the right, it indicates an increase in demand for the product. This increase in demand, when combined with an upward sloping supply curve, leads to an increase in both equilibrium price and quantity. The increase in demand causes suppliers to increase their prices to capitalize on the higher demand, resulting in an increase in equilibrium price. Additionally, suppliers will produce more of the product to meet the increased demand, leading to an increase in equilibrium quantity. Thus, both equilibrium price and quantity increase when the demand curve shifts to the right with an upward sloping supply curve.

    Rate this question:

  • 11. 

    A shift in the demand curve results from a change in price of the good. 

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    A shift in the demand curve does not result from a change in price of the good. Instead, it is caused by factors such as changes in consumer income, tastes and preferences, prices of related goods, and expectations. When any of these factors change, it causes a shift in the entire demand curve, indicating a change in the quantity demanded at every price level. Changes in price, on the other hand, result in movements along the demand curve, known as changes in quantity demanded. Therefore, the statement that a shift in the demand curve results from a change in price of the good is false.

    Each of the following will cause the demand for butter to increase except

    • A.

      An increase in the price of margarine

    • B.

      A scientific study that shows butter is good for people's health

    • C.

      An increase in the number of people who are unemployed

    • D.

      An increase in the number of people who are willing and able to purchase butter

    Correct Answer
    C. An increase in the number of people who are unemployed
    Explanation
    An increase in the number of people who are unemployed is not expected to cause the demand for butter to increase. When people are unemployed, they generally have less disposable income to spend on non-essential items like butter. Therefore, the demand for butter is unlikely to increase in this scenario.

    Rate this question:

  • 13. 

    Each of the following will cause supply for a good to increase except:

    • A.

      A government subsidy to the industry producing the good

    • B.

      A government excise tax on that good

    • C.

      A new lower cost source of electric power that is used to make that good

    • D.

      The industry invests in new technology that reduce the cost of production.

    Correct Answer
    B. A government excise tax on that good
    Explanation
    A government excise tax on that good will not cause the supply for the good to increase. In fact, it will have the opposite effect. An excise tax is a tax imposed on specific goods, and it increases the cost of production for the industry. As a result, the industry will have less incentive to produce and supply the good, leading to a decrease in supply.

    Rate this question:

  • 14. 

    Suppose the current equilibrium price for gasoline is $3.65 a gallon.  The government decides to impose a price ceiling of $2.00 a gallon.  This will cause:

    • A.

      The quantity demanded to decrease and the quantity supplied to decrease

    • B.

      The quantity demanded to decrease and the quantity supplied to increase

    • C.

      The quantity demanded to increase and the quantity supplied to increase

    • D.

      The quantity demanded to increase and the quantity supplied to decrease

    Correct Answer
    D. The quantity demanded to increase and the quantity supplied to decrease
    Explanation
    A price ceiling is a maximum price that can be charged for a product. In this case, the government imposes a price ceiling of $2.00 a gallon for gasoline, which is lower than the current equilibrium price of $3.65 a gallon. This means that the price is artificially set below the market equilibrium. As a result, the quantity demanded for gasoline will increase because consumers will be willing to buy more at the lower price. However, the quantity supplied will decrease because producers will be less willing to supply gasoline at a lower price. Therefore, the correct answer is that the quantity demanded will increase and the quantity supplied will decrease.

    Rate this question:

  • 15. 

    Predict how the equilibrium price of coffee would be affected by the following change:  Poor growing conditions for coffee beans (demand remains constant)

    • A.

      Equilibrium price would decrease

    • B.

      Equilibrium price would increase

    • C.

      Equilibrium price would remain constant

    • D.

      Equilibrium quantity would increase

    Correct Answer
    B. Equilibrium price would increase
    Explanation
    Poor growing conditions for coffee beans would lead to a decrease in the supply of coffee. With demand remaining constant, this decrease in supply would create a shortage in the market, causing the equilibrium price to increase. As the supply decreases, the quantity of coffee available in the market would also decrease, but this is not mentioned in the question.

    Rate this question:

  • 16. 

    A consumers demand of this type of good  will decrease as his or her income increases. 

    • A.

      Normal Good

    • B.

      Inferior Good

    • C.

      Substitution Effect

    • D.

      Complementary Good

    • E.

      Income effect

    Correct Answer
    B. Inferior Good
    Explanation
    An inferior good is a type of good for which demand decreases as income increases. This means that as a consumer's income rises, they are less likely to purchase this type of good. This could be due to the fact that as their income increases, they have more disposable income to spend on higher-quality goods or substitutes for the inferior good. Therefore, the given answer "Inferior Good" is correct in explaining that the consumer's demand for this type of good will decrease as their income increases.

    Rate this question:

  • 17. 

    For a ____________, a consumer's demand will increase as his or her income increases. 

    • A.

      Normal Good

    • B.

      Inferior Good

    • C.

      Substitution Effect

    • D.

      Law of Demand

    • E.

      Income effect

    Correct Answer
    A. Normal Good
    Explanation
    A normal good is a type of product for which the demand increases as the consumer's income increases. This means that as the consumer earns more money, they are willing and able to purchase more of the normal good. This is because they have more disposable income to spend on goods and services. Therefore, the correct answer is normal good.

    Rate this question:

  • 18. 

    When the price of a haircut was raised from $12 to $16, the number of hair cuts sold each day fell from 20 to 13.  What is the elasticity of demand for haircuts.

    • A.

      Elastic

    • B.

      Inelastic

    • C.

      Unitariy elastic

    Correct Answer
    A. Elastic
    Explanation
    The given answer "Elastic" is correct because when the price of haircuts increased by 33% (from $12 to $16), the quantity demanded decreased by 35% (from 20 to 13). This indicates a relatively large response in quantity demanded compared to the change in price, which is characteristic of elastic demand.

    Rate this question:

    • A.

      Is willing and able to

    • B.

      Wants to and will

    • C.

      Wants and needs

    • D.

      Are able to

    Correct Answer
    A. Is willing and able to
    Explanation
    Demand indicates the quantity of a product that a consumer is willing and able to purchase at a given price, assuming all other factors remain constant. It implies that the consumer has both the desire and the financial capability to buy the product.

    Rate this question:

  • 20. 

    Which of the following is false about demand curves?

    • A.

      They normally slope down from left to right

    • B.

      They show the relationship between price and the quantity demanded

    • C.

      They can slope down from the right to the left

    Correct Answer
    C. They can slope down from the right to the left
    Explanation
    Demand curves typically slope down from left to right because as the price of a good or service decreases, the quantity demanded tends to increase. This is known as the law of demand. However, demand curves can also slope up from right to left in certain situations, such as when there is a Giffen good, which is a type of inferior good where the quantity demanded increases as the price increases. In such cases, the income effect outweighs the substitution effect, leading to a positive slope. Therefore, the statement "They can slope down from the right to the left" is false.

    Rate this question:

  • 21. 

    Goods or services that are purchased and used in combination.

    • A.

      Normal Good

    • B.

      Inferior Good

    • C.

      Substitution Effect

    • D.

      Complementary Good

    • E.

      Demand good

    • F.

      Income effect good

    Correct Answer
    D. Complementary Good
    Explanation
    Complementary goods are goods or services that are purchased and used together in combination. They are often consumed together and are mutually beneficial to each other. For example, peanut butter and jelly are complementary goods because they are commonly used together to make a sandwich. When the price of one complementary good increases, the demand for the other complementary good decreases. This is because consumers are less likely to purchase one without the other. Therefore, the given answer, Complementary Good, correctly describes goods or services that are purchased and used in combination.

    Rate this question:

  • 22. 

    A change in the price of a good or service will NOT cause that product's demand curve to shift

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    A change in the price of a good or service will not cause that product's demand curve to shift because the demand curve represents the relationship between the price of a product and the quantity demanded at each price point. A change in price will result in a movement along the demand curve, known as a change in quantity demanded, but it will not shift the entire curve. Shifts in the demand curve are caused by factors such as changes in consumer preferences, income levels, or the prices of related goods.

    Rate this question:

  • 23. 

    Which of the two curves shows a greater price elasticity of demand?

    • A.

      D1

    • B.

      D2

    Correct Answer
    B. D2
    Explanation
    D2 shows a greater price elasticity of demand compared to D1. Price elasticity of demand measures the responsiveness of quantity demanded to changes in price. A more elastic demand curve indicates that a small change in price leads to a larger change in quantity demanded. In the case of D2, the curve is flatter, suggesting that consumers are more responsive to changes in price. This means that a small increase in price would result in a larger decrease in quantity demanded compared to D1, indicating a greater price elasticity of demand.

    Rate this question:

  • 24. 

    A government paymnet that supports a business or market is called a _______________ and _______

    • A.

      Subsidy, will increase supply

    • B.

      Subsidy, will decrease supply

    • C.

      Excise tax, will increase supply

    • D.

      Excise tax, will increase demand

    • E.

      Subsidy, will increase demand

    Correct Answer
    A. Subsidy, will increase supply
    Explanation
    A government payment that supports a business or market is called a subsidy. When a subsidy is provided, it reduces the cost of production for businesses, making it more affordable for them to produce goods or services. This, in turn, encourages businesses to increase their supply of goods or services, leading to an increase in supply in the market.

    Rate this question:

  • 25. 

    Any production cost that changes as output changes.

    • A.

      Subsidy

    • B.

      Law of Supply

    • C.

      Elasticity of Supply

    • D.

      Fixed Cost

    • E.

      Variable Cost

    Correct Answer
    E. Variable Cost
    Explanation
    Variable costs are expenses that change in proportion to the level of production or output. These costs fluctuate depending on the quantity of goods or services produced. As output increases, variable costs also increase, and vice versa. Variable costs include expenses such as raw materials, direct labor, and utilities directly related to production. Unlike fixed costs, which remain constant regardless of the level of production, variable costs are directly tied to the volume of output. Therefore, the correct answer for this question is Variable Cost.

    Rate this question:

  • 26. 

    The idea that quantity supplied will increase when the price of that product increases is called the __________.

    • A.

      Subsidy

    • B.

      Law of Supply

    • C.

      Elasticity of Supply

    • D.

      Law of Demand

    • E.

      Law of Equilibrium

    Correct Answer
    B. Law of Supply
    Explanation
    The correct answer is Law of Supply. The Law of Supply states that as the price of a product increases, the quantity supplied by producers also increases. This is because higher prices incentivize producers to supply more of the product in order to maximize their profits. Conversely, if the price of a product decreases, the quantity supplied will decrease as well. The Law of Supply is a fundamental concept in economics that helps explain the relationship between price and quantity supplied in a market.

    Rate this question:

  • 27. 

    A shift of a product's supply curve will be caused by each of the following except

    • A.

      An increase in the cost of the resources use to produce the product

    • B.

      An improvement in the technology used to produce the product

    • C.

      An increase in consumer demand for the product

    • D.

      A change in the number of suppliers that produce that product

    Correct Answer
    C. An increase in consumer demand for the product
    Explanation
    An increase in consumer demand for the product will not cause a shift of the product's supply curve. The supply curve represents the relationship between the price of a product and the quantity supplied by producers. It is determined by factors such as the cost of resources, technology, and the number of suppliers. An increase in consumer demand will only affect the demand curve, which represents the relationship between the price of a product and the quantity demanded by consumers. Therefore, it will not cause a shift in the supply curve.

    Rate this question:

  • 28. 

    Which of the following events would cause the supply curve to shift to the left?

    • A.

      A firms employees negotiate a 15% increase in their wages

    • B.

      A firm finds a new, less expensive source of materials used to make their products

    • C.

      A firm increases the price of the product.

    • D.

      None of the options

    Correct Answer
    A. A firms employees negotiate a 15% increase in their wages
    Explanation
    When a firm's employees negotiate a 15% increase in their wages, it means that the firm's labor costs have increased. This increase in labor costs will lead to higher production costs for the firm. As a result, the firm's supply curve will shift to the left because the firm is now willing to supply fewer units of the product at each price level. This is because the firm's increased costs make it less profitable to produce and sell the product at the previous price levels.

    Rate this question:

  • 29. 

    When the price of a product increases, the producer is likely to:

    • A.

      Decrease quantity supplied

    • B.

      Stop producing the good

    • C.

      Increase the quantity supplied

    • D.

      Maintain the same quantity supplied

    Correct Answer
    C. Increase the quantity supplied
    Explanation
    When the price of a product increases, the producer is likely to increase the quantity supplied. This is because a higher price incentivizes producers to supply more of the product in order to maximize their profits. As the price rises, producers can earn more revenue per unit sold, making it more profitable for them to increase their production and supply more of the product to the market. Therefore, increasing the quantity supplied is the logical response for producers when the price of a product increases.

  • 30. 

    If China placed a tax on American made Levi's that are imported to their country how would this change the supply and demand curve for Levi's jeans in China?

    • A.

      It would raise price and reduce quantity

    • B.

      It would raise price and increase quantity

    • C.

      It would lower price and increase quantity

    • D.

      It would cause no change in price and quantity

    Correct Answer
    A. It would raise price and reduce quantity
    Explanation
    If China placed a tax on American made Levi's that are imported to their country, it would raise the price of Levi's jeans in China. This is because the tax would increase the cost of importing Levi's, which would be passed on to the consumers in the form of higher prices. Additionally, the tax would reduce the quantity of Levi's jeans available in China, as the higher price would decrease the demand for Levi's. Therefore, the correct answer is that it would raise price and reduce quantity.

  • 31. 

    Assuming the concept of Ceteris Paribus (all other things held constant) a change in the price of a good, causes a movement along the supply curve and not a shift in the supply curve.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Ceteris paribus means that all other factors remain constant. In this context, it means that when the price of a good changes, assuming all other factors are held constant, it will cause a movement along the supply curve rather than a shift in the supply curve. This is because the quantity supplied of a good is directly related to its price, according to the law of supply. As the price increases, suppliers are willing to produce and sell more of the good, resulting in a movement along the supply curve. Conversely, a decrease in price would lead to a decrease in quantity supplied and a movement along the supply curve. Therefore, the statement is true.

    • D.

      A and D

    • E.

      E

    Correct Answer
    B. A,B,and C
    Explanation
    A surplus exists when the quantity supplied exceeds the quantity demanded. In this scenario, a surplus exists at points A, B, and C because the quantity supplied is greater than the quantity demanded at these price levels. At point A, the price is $2.00, and the quantity supplied is 175 while the quantity demanded is only 25.

    If the U.S. imposes a tariffs on Japanese car imports what is the most likely and immediate outcome of the decision?

    • A.

      Demand for Japanese cars will increase, the quantity supplied for Japanese cars will decrease

    • B.

      Demand for U.S. made cars will increase, and the quantity supplied of U.S. Cars will also increase.

    • C.

      The demand for U.S. made cars will decrease, and the quantity supplied of Japanese cars will increase

    • D.

      The demand of Japanese cars will increase, the quantity supplied of U.S. made cars will stay the same

    Correct Answer
    B. Demand for U.S. made cars will increase, and the quantity supplied of U.S. Cars will also increase.
    Explanation
    If the U.S. imposes tariffs on Japanese car imports, it will make Japanese cars more expensive for consumers in the U.S. As a result, the demand for Japanese cars will decrease. On the other hand, the tariffs will make U.S. made cars relatively cheaper compared to Japanese cars. This will lead to an increase in the demand for U.S. made cars. Additionally, the tariffs may incentivize U.S. car manufacturers to increase their production to meet the higher demand, resulting in an increase in the quantity supplied of U.S. cars.

    Because the cost of water increased, tomato farmers decided to decrease the supply of their crop.  What was the reason for this shift in supply?

    • A.

      Cost of inputs

    • B.

      Consumer tastes and advertising

    • C.

      Improvement in technology

    • D.

      Supply shock

    Correct Answer
    A. Cost of inputs
    Explanation
    The cost of inputs refers to the expenses incurred by tomato farmers in producing their crops. If the cost of water, which is an essential input in tomato farming, increases, it will directly impact the farmers' production costs. To maintain profitability, the farmers would then decide to decrease the supply of their crop. This shift in supply is a rational response to the increased cost of inputs, as reducing the supply allows the farmers to offset the higher expenses and maintain their profit margins.

    When the price of helmets decreased, more consumers bought bikes.  This led to an increase in the demand for helmets.  What is the reason for this shift?

    • A.

      Substitution effect

    • B.

      Complimentary goods

    • C.

      Income effect

    • D.

      Inferior good effect

    Correct Answer
    B. Complimentary goods
    Explanation
    The reason for the shift in demand for helmets is due to the concept of complimentary goods. When the price of helmets decreased, it became more affordable for consumers to purchase bikes, which are complimentary goods to helmets. As more consumers bought bikes, the demand for helmets increased because people who bought bikes also needed helmets to ensure their safety while riding. Therefore, the decrease in helmet prices led to an increase in the demand for helmets due to their complimentary relationship with bikes.
