![]() ![]() Find the consumer’s surplus and producer’s surplus at equilibrium price. Example 3.29 The demand and supply function of a commodity are pd 18 2x x2 and ps 2x 3. This paper shows that under specific conditions there is a definite. Consumer surplus, also known as buyer’s surplus, is the economic measure of a customer’s excess benefit. Solution: 140 (50 + 40) 50 units Hence the producer’s surplus 50 units. This means he gets -$1 surplus from the transaction ($1-$2). The consumer surplus that exists in case of perfect competition gets reduced in case of monopoly as a part of it goes to the monopolist in the form of monopoly profit, a part of it is lost in the form of deadweight loss while the rest remains as consumer surplus in monopoly. The third purchase results in no surplus because $2=$2, and for the last purchase he actually has a negative surplus, because he is willing to pay is less than the price he is paying. For the next, he is willing to pay $3, but pays $2 for a surplus of $1. For the first milkshake, Nick is willing to pay $4, but only has to pay $2, so his surplus is $2. First, we know that Nick ONLY pays $2 for each milkshake, regardless of the number of milkshakes he purchases. So we can go through each decision that Nick makes, and figure out what the associated consumer surplus is for that choice. It is also possible that the marginal consumer surplus (the consumer surplus from the next unit) is negative. ![]() Consumer Surplus and the Price Elasticity of Demand Consumer surplus for a product is zero when the demand for the product is perfectly elastic. However, the trick for this question is to remember that the demand curve is equal to the willingness to pay of the consumer. While taking into consideration the demand and supply curves, the formula for consumer surplus is CS (base) (height). Most people are able to remember that consumer surplus is the difference between the demand curve and the price paid by the consumer. The third milkshake $2 and for the fourth milkshake $1. Purchased Nick is willing to pay $4, for the second milkshake $3, for 4,000 Incorrect The social surplus is the area area below the demand curve and above the supply curve or the. Don't confuse it with the consumer surplus that is the area below the demand curve and above the market price line. Here is the actual question we are going to discuss in this economics post: Make sure you use the right formula to calculate the producer surplus. This post goes over one example of finding consumer surplus, if you would like more information on consumer surplus, including what it is, and how to calculate it using a general form, check out this other post. ![]()
