A small neighborhood comprised of 10 homes has a problem with break-ins and find the local police to be effective. They are cons

idering hiring private security. Each household can calculate their marginal benefit of having a private security guard by the formula MB=100/(1+S) where S is the number of hours of security patrol provided per week.
If private security is a public good and the cost is $20 per hour, what is the efficient level of security? Do you expect this to be the equilibrium outcome?

Answer:

The efficient level of security is 4 hours of security.

The equilibrium may not be sustainable.

Explanation:

In order to calculate the efficient level of security we would Set MB=MC i.e. guard's wage for net benefit maximization.

Hence, 100/(1+S)=20

20*(1+S)=10

1+S=5

S=4

Therefore, 4 hours of security is needed . The efficient level of security is 4 hours of security.

In the followig case Security guards is public good in this case, Public good is non-excludable and non-rivalrous. People cannot be stopped from using it without paying for it. Payment for security guard is voluntary. So, equilibrium may not be sustainable.

Tems11 [23]

Answer:

The options chosen are:

B. the tragedy of the commons;

C. incentive to conserve the property;

E. incentive to protect the property.

Explanation:

<em> B. The tragedy of the commons- </em>Open-access regimes can be exploited on a first-come, first-served basis, because no individual or group has the legal power to restrict access. The consequences of open access have become popularly known as what Hardin (1968) misleadingly called ‘the Tragedy of the Commons.’

<em>C. incentive to conserve the property:</em> In addition, clearly defining and assigning property rights should resolve environmental problems by internalising externalities and relying on incentives for private owners to conserve resources for the future.

<em>E.</em> The Incentive to protect the property -<em> </em><em>The incentives associated with private property rights can help conserve scarce resources: Private ownership entails penalties for premature harvesting or over-harvesting of resources. Private ownership rewards community and individual cooperation. Private ownership rewards conservation and stewardship behaviour.</em>

Linda decides to open a kiosk in the mall selling baseball hats. It costs her $2280 to stock 100 hats and $3580 to stock 500 hat
Liula [17]

Answer with Explanation:

1. Marginal Cost per Unit

As we know:

Marginal Cost per Unit = Change in Cost / Change in Quantity Bought

= ($3580 - $2280) / (500 - 100)

= $3.25 per Unit

2. Fixed Cost to setup

The fixed cost would be $2280 because it is the cost that is required for setting up the kiosk. The cost $3580 is not relevant because it depends on the demand of the product. The least cost to set up kiosk is $2280.

3. Cost Function

Total Cost = Fixed Cost + Variable Cost

As we know that:

Variable Cost = Marginal cost per unit * Number of units = $3.25 * x = 3.25x

For Fixed cost $2280

By putting this value in the above equation, we have:

Total Cost = $2280 + 3.25x

C(x) = $2280 + 3.25x

And

For Fixed cost $3580

C(x) = $3580 + 3.25x

4. Revenue Function

Total Revenue = Selling Price per Unit  *  Total Units

Here

Selling price is $8 and total units are "x"

By putting values, we have:

Total Revenue = $8 * x

R(x) = 8x

5. Breakeven Point For $2280 and $3580

As we know that

Breakeven Point = Fixed Cost / Contribution Per unit

For Fixed Cost $2280:

Breakeven Point = $2280 / ($8 - $3.25)

= 480 Units

For Fixed Cost $2280:

Breakeven Point = $3580 / ($8 - $3.25)

= 754 Units

6. Profit Function

For Fixed Cost $2280:

Profit = Revenue Function - Cost Function

P(x) = 8x  -  ($2280 + 3.25x)

P(x) = 8x - $2280 - 3.25x

P(x) = 4.75x - $2280

For Fixed Cost $3580:

P(x) = 4.75x - $3580

7. Claire's Profit if she sells 1,000 bottles

Using the above profit function for fixed cost $2280, we have:

P(x) = 4.75x - $2280

Here x is 1,000 units, which means:

P(x) = 4.75 * 1,000   -   $2280

P(x) = $4,750 - $2280 = $2,470

Using the above profit function for fixed cost $3,580, we have:

P(x) = 4.75x - $3,580

Here x is 1,000 units, which means:

P(x) = 4.75 * 1,000   -   $3,580

P(x) = $4,750 - $3,580 = $1,170

a) ( 0.8509718, 0.8890282)

b) ( 0.7255, 0.7745)

Explanation:

(a)

Given that , a = 0.05, Z(0.025) =1.96 (from standard normal table)

So Margin of error = Z × sqrt(p × (1-p)/n) = 1.96 × sqrt(0.87 × (1-0.87) / 1200)

=0.01902816

So 95 % confidence interval is

p+/-E  

0.87+/-0.01902816  

( 0.8509718, 0.8890282)

(b)

Margin of error = 1.96 × sqrt (0.75 × (1-0.75) / 1200) = 0.0245

So 95% confidence interval is

p+/-E

0.75+/-0.0245

( 0.7255, 0.7745)
