When output occurs at the intersection of marginal social benefit (MSB) and marginal social cost (MSC)
, the socially optimal level of output is achieved. Also known as the allocatively efficient
Answer: To find the socially optimal amount of the good we need to
set the market demand curve equal to the marginal cost curve
. Here we assume that both the demand curve and the marginal cost curve include all the benefits and all the costs, respectively, that society faces with this good.
The output level that reflects all the costs and benefits associated with a transaction
i.e. it is the equilibrium that would be achieved if the market outcome reflects the effect of externalities.
Quick Reference. The point on the utility possibility frontier that maximizes social welfare. The social optimum is
the allocation chosen by a benevolent social planner who is constrained only by the endowment of resources
.
The allocatively efficient quantity of output, or the socially optimal quantity, is
where the demand equals marginal cost, but
the monopoly will not produce at this point. Instead, a monopoly produces too little output at too high a cost, resulting in deadweight loss.
When output occurs
at the intersection of marginal social benefit (MSB) and marginal social cost (MSC)
, the socially optimal level of output is achieved. Also known as the allocatively efficient level of output. If output occurs at any other level, a market failure exists.
The MSC curve is given by MSC=Q+2 → Set the MSC equal to the marginal so- cial benefit (in this case the MSB is the market demand curve) to find the so- cially optimal amount of the good.
30-Q=Q+2 → Q =14
is the socially optimal amount of the good.
Because
individuals actions fail to account for the impact on others
, a negative externality exists. When a positive externality is present, the market produces less than the socially optimal quantity of the good or service, since there is a benefit to society that is not captured by the individual.
The government can use
command-and-control policies to regulate behavior
directly. Alternatively, it can implement market-based policies such as taxes and subsidies to incentivize private decision makers to change their own behavior.
The socially efficient level of output is
that quantity that maximizes the sum of the consumer and producer surpluses
. It is the most efficient output level because the marginal social benefit of producing and consuming another unit equals the marginal social cost.
Pareto defined social optimum as
a position from which no reorganization of production and exchange can be effected to make anyone better off without making somebody else worse off
.
Social efficiency, as Snedden defines it, is
the position in education
.
that calls for the direct teaching of knowledge, attitudes, and skills

intended to shape the individual to predetermined social characteris
– tics. Social efficiency presumes to improve society by making its.
The socially optimal quantity of pollution is
QOPT
; at that quantity, the marginal social bene- fit of pollution is equal to the marginal social cost, corresponding to $200. savings to a polluter of being allowed to emit one more ton rises.
A Socially Optimal Price is
a price where the monopoly reaches allocative efficiency (DARP=MC)
. Since a price ceiling that low would cause some monopolies to incur an economic loss, a Fair Return Price is a viable alternative. The Fair Return Price is found where price equals Average Total Cost (DARP=ATC).
What is deadweight loss formula?
Deadweight loss is defined as the loss to society that is caused by price controls and taxes. … In order to calculate deadweight loss, you need to know the change in price and the change in quantity demanded. The formula to make the calculation is:
Deadweight Loss = . 5 * (P2 – P1) * (Q1 – Q2).
What is a harmful externality?
An externality is a cost or benefit caused by a producer that is not financially incurred or received by that producer. … For example, a negative externality is a
business that causes pollution that diminishes the property values or health
of people in the surrounding area.
