State with brief reason whether the following statements are true, false, or uncertain:a. In the presence of heteroscedasticity

OLS estimators are biased as well as inefficient.b. If heteroscedasticity is present, the conventional t and F tests are invalid.c. In the presence of heteroscedasticity the usual OLS method always overestimates the standard errors of estimators.d. If residuals estimated from an OLS regression exhibit a systematic pattern, it means heteroscedasticity is present in the data.e. There is no general test of heteroscedasticity that is free of any assumption about which variable the error term is correlated with.f. If a regression model is mis-specified (e.g., an important variable is omitted), the OLS residuals will show a distinct pattern.g. If a regressor that has nonconstant variance is (incorrectly) omitted from a model, the (OLS) residuals will be heteroscedastic.

expeople1 [14]

Answer:

d. Choose Option B because it has a higher NPV

Explanation:

The computation is shown below:

For Option A:

Investment = $10 million

Present Value of cash flows = Cash flow ÷ Discounting rate

= $2 ÷  10%

= $20 million

Now

NPV = $20 - $10

= $10 million

We know that

IRR is the rate at which the NPV will be zero

So,  2 ÷  r - 10 = 0

r = 20%

For Option B:

Investment = $50 million

Present Value of cash flows = $6.5 ÷  10% = $65 million

NPV = $65 - $50 = $15 million

we know that

IRR is the rate at which the NPV will be zero

So, 6.5÷ r -50 = 0

r = 13%

Based on NPV, Option B should be selected as it contains higher NPV as compared to option A.

However, Based on IRR, Option A should be chosen as it contains higher IRR and a higher IRR represent a higher profit percentage

alexdok [17]

Answer:

Lies below its demand curve and is steeper than its demand curve.

Explanation:

The marginal revenue curve for a monopolist lies below the demand curve because of the quantity effect. The quantity effect refers to the fact that even a monopolist must lower its price if it wants to sell a larger quantity of goods or services.

The slope of the marginal revenue curve is steeper than the demand curve because it reflects the market power of the monopolist. Instead, the marginal revenue curve for a perfectly competitive firm (with 0 market power) is horizontal or perfectly elastic.
