Theory tells us that the real interest rate equals the marginal
product
of capital less the depreciation rate. Theory also tells us that
the marginal
product of capital decreases when the capital-labor ratio
increases. We know
from observation that the capital-labor ratio has been rising
steadily for over a
century, but that the real interest rate and the depreciation rate
have remained
relatively constant. How can all of these statements be correct?
Explain.
Hint: One possible answer uses technological change in an important
way.
Graphing the production function for different technology levels
may be helpful.

Given the following information
n= 5 Σ Xt = 30 Σ Yt = 172 Σ Yt Xt = 980
Σ X2t = 205 Σ Y2t = 5162
Find the least squares estimates of α and β from
Yt = α + βXt + ut
The sum of squared residuals is 45.2691. What does the SSR tell us in general?
Find the unbiased estimate of the variance of ut. What does S2 tell us in general?
Test H0: β = 0 against H1: β > 0 at the 5% level of significance.
Calculate the 95% confidence interval for β.
Calculate the R2.

At a retail selling price of $2.5, Pepsi will be able to cover 15% of the approximately 1 billion units (20 oz. bottles) premium water market in US. If retailers charge a margin of 20% and if Pepsi’s unit variable cost in making and selling a bottle of LIFEWATR is $1, and Pepsi will incur a total fixed cost (in manufacturing, advertising, branding etc.) of $75 million, what is the profit that it can expect from the product? At $2, Pepsi will cover 20% of the premium water market in US. Do you think they should price the product at $2? Assume that there are no whole sellers between Pepsi and its retailers.

A study is conducted to determine the security and confidentiality of personal information submitted over the Internet, including such things as social insurance and credit card numbers. A random sample of 1,000 adults were selected and asked under what circumstances they would give personal information to a company. 20% said they would never give personal data to a company, while 51% said they would if the company had strict privacy guidelines in place. Construct a 95% confidence interval for the proportion of those who would never give personal data to a company.
