Given the following demand and supply function of the potato chips
The
To calculate equilibrium, we need to substitute
Hence, the equilibrium quantity and price with respect to given demand and supply function is Q = 20 and P = $40.
In order to calculate conumer surplus, producer surplus and social welfare we need to plot the above demand and supply function.
In the graph, the x axis depicts the quantity of potato chips and the y axis depicts the price per potato chips (in $),
Consumer surplus in the graph is represented by triangle A, so to compute consumer surplus, we need to calculate the area of the triangle. Thus, consumer surplus (CS) is
Producer surplus in the graph is represented by triangle B, so to compute producer surplus, we need to calculate the area of the triangle. Thus, producer surplus (PS) is
Social welfare (SW) is the sum of consumer surplus and producer surplus. Thus,
Introduction:
The equilibrium price is the defined as the price level at which both consumer and producer satisfies. It is the price where both want to exchange commodities and services.
b)

b)
Explanation of Solution
Given information:
Perceived demand function,
Supply function,
The equilibrium price is calculated by equating the supply and demand function. Thus, in equilibrium
In order to calculate equilibrium quantity, we need to substitute P = $80 into either the demand or supply function. Thus, equilibrium quantity is
Hence, the equilibrium quantity and price with respect to given demand and supply function is
In order to calculate deadweight loss we need to plot the above demand function and supply function. This has been done below:
In the graph, the x axis measures the quantity of potato chips and the y axis measures the price per potato chips (in $),
When it assumed that consumer behavious is influenced by his or her limited cognitive ability, then his percieved demand curve is
The deadweight loss indicating loss in social welfare due to extra purchase of potato chips than required is represented by triangle C and D. to compute the deadweight loss we need to calculate the area of triangle C and D. Thus
Thus, deadweight loss is
Introduction: A deadweight loss is an expense to economy that is caused by market failure, when supply and demand are out of equilibrium. Primarily used in economics, deadweight loss can be extended to any deficit caused by inadequate resource allocation.
c)
To compute: The per unit tax that the government could impose to correct the deadweight loss problem.
c)
Explanation of Solution
In order to correct the deadweight loss of 500 due to extra purchase of potato chips, government could impose a specific tax,
As a result, the consumer will reduce its purchase of potato chips from 40 units to 20 units on account of increased price of potato chips to $90.
Introduction: A deadweight loss is an expense to economy that is caused by market failure, when supply and demand are out of equilibrium. Primarily used in economics, the loss of deadweight can be extended to any deficit caused by inadequate resource allocation.
d)
To compute: The deadweight loss the governement has introduced with the tax if instead the government made a mistake and the second demand is actually the true demand stemming from rational decisions.
d)
Explanation of Solution
Dead weight loss happens when there is no equilibrium between supply and demand which leads to market failure. Market inefficiency happens when products are either overvalued or undervalued inside the industry. Although the disparity will favor some people in society, a change from equilibrium would negatively affect others.
If it is assumed that

- Consider two treatments. Treatment 1 saves one year of life at a cost of $10,000. Treatment 2 saves ten years of life at a cost of $1,000,000. Which treatment is more cost-effective? Why? Consider two treatments. Treatment 1 saves six years of quality adjusted life at a cost of $90,000. Treatment 2 saves three years of quality adjusted life at a cost of $60,000. Which treatment is preferred from a cost utility analysis perspective? Suppose Jay has been experiencing back pain and that there are two options for back pain: Treatment Regimen Total Cost Pain Reduction Do nothing $0 0 units Cortisone injections $600 30 units Calculate the ICER between cortisone injections and doing nothing. Jay says he is willing to pay $10 for a per unit of pain reduction. Should he choose cortisone injections? Another treatment is discovered. It costs $700 and reduces pain by 25 units. Should he choose the new treatment?arrow_forwardBehavioral economics a. integrates psychological insights into economic models. b. relies on the assumption that homo economicus describes economic decision-making. c. assumes that economic agents have full information about the conditions surrounding their decisions. d.
