Multiple Choice Questions
- Question 1: Market equilibrium is determined by the balance between supply and demand, not the mismatch.
- Question 1 (Correct Answer): At equilibrium, quantity demanded equals quantity supplied.
- Question 1 (Incorrect Option 1): Equilibrium is not defined by mismatch.
- Question 1 (Incorrect Option 2): At equilibrium price, supply and demand are equal.
- Question 1 (Incorrect Option 3): Demand curve is based on consumer preferences.
- Question 1 (Incorrect Option 4): Markets naturally seek equilibrium, not disequilibrium.
- Question 2: A price increase leads to a decrease in demand, causing a movement along the demand curve.
- Question 2 (Correct Answer): The right graph illustrates this, as the event is linked to the change of price which results in the shift of the demand curve.
- Question 2 (Incorrect Option 1): A change in quantity demanded leads to a movement along the curve.
- Question 2 (Incorrect Option 2): A price change affects the whole demand curve.
- Question 2 (Incorrect Option 3): A change in price results in a shift, not a movement along the curve.
- Question 3: Finding market supply at €0.30; Market supply is the sum of individual supply schedules.
- Question 3 (Correct Answer): Richard's 5 plus Megan's 7 equals 12 units of milk at a price of €0.30.
- Question 3 (Incorrect Option 1): This answer miscalculates the combined supply.
- Question 3 (Incorrect Option 2): This option incorrectly calculates the aggregate for the market supply.
- Question 3 (Incorrect Option 3): This answer only takes into account the highest producer.
- Question 4: Area Z on the supply-demand graph represents the surplus.
- Question 4 (Correct Answer): Z denotes the surplus when the quantity supplied outpaces the quantity demanded, in this case 7 units.
- Question 4 (Incorrect Option 1): Incorrect calculation of the surplus (10 units supplied).
- Question 4 (Incorrect Option 2): Surplus is the difference between supply and demand, not just one side.
- Question 4 (Incorrect Option 3): Z represents a surplus.
- Question 5: Less elastic demand means more price sensitivity, a steeper demand curve and quantity demanded is lower after price change.
- Question 5(Correct Answer): Good A has a steeper demand curve, indicating a less elastic demand.
- Question 5 (Incorrect Option 1): Steeper curve implies less responsiveness .
- Question 5 (Incorrect Option 2): Both are the same.
- Question 5 (Incorrect Option 3): Steeper curve implies less responsiveness.
- Question 6: Indifference curves cannot cross, representing the consumer's preferences.
- Question 6 (Correct Answer): Indifference curves cannot intersect since that would indicate preferences in a single point in disagreement
- Question 6 (Incorrect Option 1): Indifference curves reflect preferences, not the opposite.
- Question 6 (Incorrect Option 2): Intersecting indifference curves are problematic in illustrating preferences.
- Question 6 (Incorrect Option 3): The slope does not define the entire curve.
- Question 7: Change in the relative price of cheese and wine causes a change in the slope of the budget line.
- Question 7 (Correct Answer): The price of wine rising or falling results in a differing slope of the budget line.
- Question 7 (Incorrect Option 1): Demand is irrelevant to the ratio between price.
- Question 7 (Incorrect Option 2): A price change creates the modified budget line and associated changes in the slope.
- Question 7(Incorrect Option 3): Demand fluctuations affect demand.
- Question 8: Points on the indifference curve are evaluated equally; points with additional options are preferable.
- Question 8 (Correct Answer): Points on the same indifference curve are equally desirable, in accordance with the consumer's preferences.
- Question 8 (Incorrect Option 1): Points higher on the curve indicate greater desirability, based on the same indifference criteria.
- Question 8 (Incorrect Option 2): This is the exact opposite.
- Question 8 (Incorrect Option 3): Equally desirable points are on a single indifference curve.
- Question 9: A reduction in income affects the quantity of inferior goods demanded positively.
- Question 9 (Correct Answer): Inferior goods: A lowering of income leads to a higher demand.
- Question 9 (Incorrect Option 1): Normal goods, not inferior goods.
- Question 9 (Incorrect Option 2): Normal goods, not inferior goods.
- Question 9 (Incorrect Option 3): The change in income results in an increase for inferior goods and not normal goods.
- Question 10: Plotting demand curve involves a pivoting of the budget line.
- Question 10 (Correct Answer): The graphs show the change in the price of a commodity.
- Question 10 (Incorrect Option 1): Deriving it involves more than a shift in the budget.
- Question 10 (Incorrect Option 2): Shifts in the demand are due to price changes in other goods.
- Question 10 (Incorrect Option 3): Shifts in the demand are due to price changes in other goods.
- Question 11: Perfect competition: Price equals marginal revenue (MR) and marginal cost (MC).
- Question 11 (Correct Answer): Profit-maximizing condition for a perfectly competitive firm is that marginal revenue equals marginal cost.
- Question 11 (Incorrect Option 1): Price equals average revenue, not marginal revenue.
- Question 11 (Incorrect Option 2): Marginal revenue equals marginal cost conditions.
- Question 11` (Incorrect Option 3): MR = MC is the profit maximising condition.
- Question 11 (Incorrect Option 4): This is false and incorrect
- Question 12: Average total cost curve (ATC) initially declines and ascends.
- Question 12(Correct Answer): Curve 2 shows average costs decreasing initially and eventually increasing due to higher variable costs.
- Question 12 (Incorrect Option 1): Costs increase steadily.
- Question 12 (Incorrect Option 2): This is the correct interpretation.
- Question 12 (Incorrect Option 3): Costs always remain under marginal cost, which is not always true.
- Question 12 (Incorrect Option 4): Costs always decrease with a decreasing price.
- Question 13: Fixed costs do not start at zero for total costs since the initial operating costs are not included in a zero cost function.
- Question 13(Correct answer): Fixed costs must be accounted for in calculating total costs.
- Question 13 (Incorrect Option 1): The cost curve does not equate to starting at zero.
- Question 13 (Incorrect Option 2): This is not the case for the starting of any function, including here.
- Question 13 (Incorrect Option 3): This response does not reflect fixed production costs.
- Question 14: Economic profit involves accounting profit, opportunity costs, and revenue.
- Question 14 (Correct Answer): Considering the opportunity costs, your economic profit is -£20,000.
- Question 14 (Incorrect Option 1): The opportunity cost of the next best alternative job is not calculated directly.
- Question 14 (Incorrect Option 2): The calculation for the profit is incorrect.
- Question 14 (Incorrect Option 3): The opportunity costs are not correctly calculated
- Question 14 (Incorrect Option 4): The alternative job and capital losses from opportunity are essential for that calculation.
- Question 15: Perfectly competitive markets: Firms do not influence price; firms are price takers; their price matches their average and marginal revenue.
- Question 15 (Correct Answer): The firm is willing to supply product on the market since the average total costs are below the intersection point of MC and MR.
- Question 15 (Incorrect Option 1): Firm behavior is not dependent on the average cost.
- Question 15 (Incorrect Option 2): ATC is above the intersection, implying the firm would not be willing to supply at the market price.
- Question 15 (Incorrect Option 3): Opportunity for profit exists only under imperfect competition.
- Question 15 (Incorrect Option 4): ATC is below the point, meaning firm should produce.
