Neoclassical Model of Investment" (1 point): In class, we discussed the idea of net investment, and how it could change in respo

statuscvo [17]

Answer:

Take Note that the model has following relationship between investment and factors that affect it

Int = F(Ye, it, d, πe, tc, Kt-1)

Net investment is a function of

Expected output (Ye),

Rental or user cost of capital (such as nominal interest rate it),

Expected inflation (πe),

Corporate tax/ investment tax credit,

Existing stock of capital

For a given stock of capital,

A rise in expected output (Ye), increases investment

A rise in expected inflation (πe) increases investment

A rise in the investment tax credit increases investment.

A rise in nominal/real rate of interest decreases investment

A rise in corporate income tax decreases net investment

(a) Anti-inflationary monetary policy raises the real interest rate (r ↑). As mentioned, it will depress net investment as firms have to pay a higher rate of interest on the investment made. Such policy increases rental cost of capital and it will decrease the desired capital stock.

b) An earthquake destroys part of the capital stock (K ↓). This will reduce net investment, increases rental cost of capital and it will decrease the desired capital stock.

(c) Immigration of foreign workers increases the size of the labor force (L ↑). With more workers to share the capital stock, marginal producivity of capital rises and so net investment increases. This decreases rental cost of capital and it will increase the desired capital stock.

(d) Advances in computer technology make production more efficient (A ). This causes the net investment to increase as the marginal productivity of capital will increase. This decreases rental cost of capital and it will increase the desired capital stock.

Suppose that a chicken farm uses a nearby stream to dispose of the wastes released by its chickens. These wastes flow downstream

Harlamova29_29 [7]

Answer:

Suppose that a chicken farm uses a nearby stream to dispose of the wastes released by its chickens. These wastes flow downstream into a lake that has become thick with algae and polluted due to the minerals in the waste matter. The local office of a nonprofit environmental organization successfully lobbies state regulators to stop the farm's pollution.

It's important to note that sometimes private solutions to externalities do not work. For example, this occurs when communications barriers or social customs are important enough relative to the potential gains involved that a private solution is not feasible.

Explanation:

The type of private solution to the externality of pollution occurred in this case is Charities , because the work done by a non-profit organization is a form of charity.

It is crucial to note that sometimes private solutions to externalities do not work for example, this occurs when one party repeatedly holds out for a better deal.This describes the problem of a breakdown in bargaining.

The Centers for Disease Control and Prevention (CDC) defines a healthy sleep duration

laiz [17]

a. The point estimate of the married people that sleep well is = 0.6299. The confidence interval for the mean hours of sleep for those that have never been married but report good sleep is 0.6186, 0.6412

b. The point estimate of the number of hours for people that have never been married = 7.2257

95% confidence interval for the mean number of hours of sleep for those who have never been married = 7.2065, 7.2447

c. the estimated number of sleep for those that have never been married = 7.729 hours

a. The point estimate

$P=\frac{Xp}{n}$

$Xp = successes\\n = sample size\\$

Those who have never been married n = 7044

Xp = those who sleep for 7 hours at least

To get Xp, the <u>excel function </u>

Countif(range, criteria)

Countif(A:A, >=7)

This gives Xp = 4437

Point estimate =

$\frac{4477}{7044}$

= 0.6299

The point estimate of the married people that sleep well is = 0.6299

At 95% interval of confidence,

α = 1-0.95 = 0.05

α/2 = 0.05/2 = 0.025

Z0.025 = 1.96 ( Use the standard probability normal table)

Margin of Error

= $M.E = 1.96\sqrt \frac{0.6299(1-0.6299)}{7044} \\\\= 1.96\sqrt{0.000033} \\\\1.96*0.0057$

= 0.0113

The 95% confidence interval

= 0.6299 - 0.0113 , 0.6299 + 0.0113

= 0.6186, 0.6412

The confidence interval for the mean hours of sleep for those that have never been married is 0.6186, 0.6412

b. Sample mean

x = ∑x/n

x = number of sleep of the never been married

Mean is calculated using excel function

Average(range)

Average(a:a)

This gives the sample mean = 7.2257

The point estimate of the number of hours for people that have never been married = 7.2257

<u>Standard deviation</u> using excel =

Stdev(A:A) = 0.8211

$Margin of error =1.96*\frac{0.8211}{\sqrt{7044} }$

= 0.0192

The<u> confidence interval</u> =

= 7.2257-0.0192, 7.2257+0.0192

= 7.2065, 7.2447

95% confidence interval for the mean number of hours of sleep for those who have never been married = 7.2065, 7.2447

c. From the available data, the mean number of sleep per day that is gotten from the 4437 people that are unmarried and sleep healthily for at least 7 hours = 34295.1

Mean = 34295.1/4437

= 7.729

the estimated number of sleep for those that have never been married = 7.729 hours

What would be the purchase price for a $5,000, 91-day T-bill paying 3% interest?

Nat2105 [25]

Well, you just need to find it using this formula :

5,000 x [100 % - (3% x 91/365)]

= 5,000 x [ 100 % - 0.007479]

= 5,000 x 99.992521

= $ 4,962.50 >>> rounded

Hope this help

ATech has fixed costs of $7 million and profits of $4 million. Its competitor, ZTech, is roughly the same size and this year ear

Triss [41]

Answer: Degree of Operating Leverage

A Tech = 2.75

Z Tech = 3

Explanation:

As defined in question itself,

Degree of Operating Leverage = $1 + \frac{fixed\ cost}{Profit}$

As here, it is provided that profit for both the companies are same amounting $4 million.

Although the fixed cost differ by $1 million.

A Tech Degree of operating Leverage = 1 + $\frac{7,000,000}{4,000,000}$ = 2.75

Z Tech Degree of Operating Leverage = 1 + $\frac{8,000,000}{4,000,000}$ = 3

This clearly demonstrates that A Tech will reach its break even faster than the Z Tech as the ratio of fixed cost to variable cost is lower in A tech in comparison to Z Tech.
