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.
How do you find the optimal quantity of a public good?
The optimal quantity of the public good occurs
where MB (society’s marginal benefit) equals MC (provider’s marginal cost)
, or where the two curves intersect. When MB = MC, resources have been allocated efficiently. Optimal Quantity of a Public Good: The optimal quantity of public good occurs where MB = MC.
How do you determine what is a public good?
How Public Goods Work. The two main criteria that distinguish a public good are that
it must be non-rivalrous and non-excludable
. Non-rivalrous means that the goods do not dwindle in supply as more people consume them; non-excludability means that the good is available to all citizens.
How do you solve for optimal price and quantity?
Our formula for optimal pricing tells us that
p* = c – q / (dq/dp)
. Here, marginal costs are a bit sneaky — they enter directly, through the c, but also indirectly because a change in marginal cost will change prices which in turn changes both q and dq/dp.
How do you calculate optimal level of activity?
The optimal level of the activity is attained when no further increases in net benefit are possible for any changes in the activity. This point occurs at the activity level for which marginal benefit equals marginal cost:
MB = MC
.
Which of these is the best example of a public good?
The correct answer is: a)
National Defense
.
The national defense is an example of a public good because it is non-excludable and non-rivalrous.

How do you determine optimal order size?
Also referred to as ‘optimum lot size,’ the economic order quantity, or EOQ, is a calculation designed to find the optimal order quantity for businesses to minimize logistics costs, warehousing space, stockouts, and overstock costs. The formula is:
EOQ = square root of:
[2(setup costs)(demand rate)] / holding costs.
Why is MB MC optimal?
When marginal cost exceeds marginal benefit (MC>MB), then
it costs us more to produce the last unit than the benefits we derive from that last unit
. This means we could be better off if we reduced production. Too much of he good is produced and there is inefficient overproduction of the good.
How do you find the optimal price in Monopoly?
A monopolist can determine its profit-maximizing price and quantity by
analyzing the marginal revenue and marginal costs of producing an extra unit
. If the marginal revenue exceeds the marginal cost, then the firm should produce the extra unit.
Which of the following is an example of a public good in America?
An example of a public good is:
national defense
. An economist would be most likely to argue that U.S. national defense should be funded through tax revenues because: individuals who refuse to contribute to a national defense fund cannot be excluded from benefiting from national defense.
What is the value of net benefit at the optimal level of activity?
Answer and Explanation: The optimal level of activity will be at A=3, where the net marginal benefit is maximum. At the optimal level of activity, the net benefit is
$55
.
What is an example of a common good?
Wild fish are an example of common goods. They are non-excludable, as it is impossible to prevent people from catching fish. They are, however, rivalrous, as the same fish cannot be caught more than once.
Which one of the following is not a public good?
Detailed Solution
Electricity is not provided free. People pay for the service or the unit of electricity they consume.
National Defence, Light House
, and Public Parks are an example of Public goods as people are not charged for it by the government.
Which of the following is true concerning a public good?
Which of the following is true concerning a public good?
It is both non-rival and non-excludable
.
What is critical in determining whether something is produced as a public good?
Cost
is critical in determining whether something gets produced as a public good. When a good or service is public, the benefit to each individual is less than the cost that each would have to pay if it were provided privately and the total benefits to society are greater than the total cost.
The free rider problem is that with fewer contributors, or underestimated benefits,
groups may produce less of a good than is socially optimal
. … Even where exclusion is possible, exclusion may be a poor social choice for non-rival goods since no costs are saved and benefits are lost.
Is public health a public good?
Public goods—including population health—require public support and investment by
every sector
. The returns on investment are high and accrue to all. Accepting population health as a public good can be the basis for developing and aligning e ective investments for prevention, innovation, and access to care.
What two characteristics must a good have to be considered a pure public good?
The two main criteria that distinguish a public good are that it must be
non-rivalrous and non-excludable
. Non-rivalrous means that the goods do not dwindle in supply as more people consume them; non-excludability means that the good is available to all citizens.
Is a healthy local economy a public good?
Health generally is not considered a public good
, because non-paying individuals (for health insurance, healthy food, etc.)
What is the optimal production quantity?
A production lot is manufactured in a number of sub-batches of sizes which reduce the total manufacturing cycle time of a production lot. The production quantity is considered ‘optimum’
when the sum of all the costs is minimized
.
How do interest rates affect the optimal order quantity Q *?
How do interest rates affect the optimal order quantity Q*? a.
As interest rates increase, Q* decreases
. … As interest rates increase, Q* increases until it reaches a maximum, after which any further increase in interest causes a decline in Q*.
How do you calculate stock order quantity?
Order Quantity Formula
To calculate the optimum order quantity “Q,” take the square root of the following:
“2N” multiplied by “P” and divided by “H.”
“N” is the number of units sold per year, “P” is the cost to place one order and “H” is the cost of holding one unit of inventory for one year.
What is MB and MC?
Economists are making wise choices by comparing the extra benefit to the corresponding extra cost at each decision. The extra benefit is called
Marginal benefit
(MB); the extra cost is called Marginal cost (MC). You should only choose an item when its MB is greater or equal to its MC.
What does MB mean in economics?
A
marginal benefit
is the maximum amount of money a consumer is willing to pay for an additional good or service.
How is marginal analysis used?
Marginal analysis is an examination of the additional benefits of an activity compared to the additional costs incurred by that same activity. Companies use marginal analysis as
a decision-making tool to help them maximize their potential profits
.
How do economists define marginal benefit for an individual?
A marginal benefit is
a maximum amount a consumer is willing to pay for an additional good or service
. It is also the additional satisfaction or utility that a consumer receives when the additional good or service is purchased.
How do you calculate quantity output?
The rule for a profit-maximizing perfectly competitive firm is to produce the level
of output where Price= MR = MC
, so the raspberry farmer will produce a quantity of 90, which is labeled as e in Figure 4 (a). Remember that the area of a rectangle is equal to its base multiplied by its height.
How do you calculate external marginal benefit?
So, marginal external benefit =
(1/20)Q
, and marginal private benefit = 80 – (1/4)Q.
When someone compares marginal benefits associated with an activity to its marginal cost that person is making a decision?
2) A decision involves
marginal analysis
when the marginal benefits associated with an activity are compared to its marginal costs.
What is optimal price?
The optimal price is that
price point at which the total profit of the seller is maximized
. When the price is too low, the seller is moving a large number of units but is not earning the highest possible aggregate profit.
