Graphically, market demand for a product:

a)is the horizontal difference of the individual demand curves.

b)is the horizontal sum of the individual demand curves.

c)is the vertical difference of the individual demand curves.

d)is the vertical sum of the individual demand curves.

Expert Solution

Answer: The correct answer is option B i.e. horizontal sum of the individual demand curves.

Explanation: Suppose there are two individuals A and B. Then for a given price say P1 each individual will have their individual demand curves. Since the price remains the same across individuals for a particular good the only variable that varies is the quantity along horizontal axis. So we add the individual demands for each price and thus finally arrive at the market demand of a product. In other words by doing horizontal summation, a quantity demanded by all the consumers in the market is added at each price level.

To obtain the market demand curve for a product, sum the individual demand curves

Question 14 To obtain the market demand curve for a product, sum the individual demand curves horizontally. vertically. diagonally. and then average'them. Question 15 When a buyer's willingness to pay for a good is equal to the price of the good, the buyer's consumer surplus for that good is maximized. price of the good exceeds the value that the buyer places on the good. buyer is indifferent between buying the good and not buying it. buyer will buy as much of the good as the buyer's budget...

1A) Describe the difference between the market demand curve and each firm's individual demand curve in perfect competition. 1B ) For a perfectly competitive firm, the marginal cost curve is the same thing as that firm’s supply curve starting from the minimum point on the average variable cost curve because at every possible price; by finding the intersection of MR (where, MR = Price = Demand) & MC we find the quantity that will be produced. The description of how...

The market for a product is defined by the following demand and supply curves: Qd=26-0.1P Qs=-10+0.3P Assume that an ad valorem tax of 50 per cent (i.e. t=0.5) is placed on the product. (a) On the diagram you have drawn in (i), add the new supply curve reflecting the impact of the ad valorem tax. (b) Derive mathematically the new equilibrium consumer and producer prices and quantity. (c) Find the amount of tax revenue gained by the...
