Answers

Answer 1

We need approximately 1536 years. Using the convergence rate given by the Central Limit Theorem.

To estimate μ with a 95% confidence interval of the form [μ^ - 0.01, μ^ + 0.01], we can use the convergence rate provided by the Central Limit Theorem, which is σ/√N, where N is the number of samples or observations.

Given that Δ = 1/252 years and σ = 0.2 per year, we can use the convergence rate formula to solve for N:

0.01 = 1.96 * (0.2/√N)

Squaring both sides and rearranging the equation, we have:

0.0001 = 1.96^2 * 0.04/N

N = 1.96^2 * 0.04 / 0.0001

N ≈ 1536

Therefore, you would need approximately 1536 years of data to estimate μ with a 95% confidence interval of ±0.01 using the convergence rate given by the Central Limit Theorem.

The cross-over point for two types of machine-producing widgets is 25,000 units. Machine A has a fixed cost of P100,000 and a variable cost of P8 per widget.  

Machine B has a fixed cost of P250,000. What is the variable cost of Machine B? The variable cost of Machine B is P12.00. Variable cost refers to the costs that are incurred by a company during the production of goods or services, which can fluctuate depending on the volume of production. The formula for calculating the variable cost is:

Variable cost = (Total cost – Fixed cost) / Number of units produced From the given information, we know that the cross-over point for the two types of machine-producing widgets is 25,000 units. Let's find the total cost of both machines and then use the formula to calculate the variable cost of Machine B. The total cost of Machine A is:

Total cost of Machine A = Fixed cost of Machine A + Variable cost of Machine A × Number of units produced

Total cost of Machine A = 100,000 + 8 × 25,000

Total cost of Machine A = 300,000

The total cost of Machine B is:

Total cost of Machine B = Fixed cost of Machine B + Variable cost of Machine B × Number of units produced

Total cost of Machine B = 250,000 + Variable cost of Machine B × 25,000

We know that the cross-over point for both machines is 25,000 units, so we can set the total cost of Machine A equal to the total cost of Machine B:

Total cost of Machine A = Total cost of Machine B 300,000 = 250,000 + Variable cost of Machine B × 25,000

Variable cost of Machine B = (300,000 - 250,000) / 25,000 Variable cost of Machine B = 50,000 / 25,000Variable cost of Machine B = P12.00. Therefore, the variable cost of Machine B is P12.00.

The fixed costs will $415,000 per year. The project will require an initial investment in net working capital of $201,000 that will be recovered at the end of the project. The required return is 10.9 percent and the tax rate is 34 percent. What is the NPV? Multiple Choice $642,663 $1,032,186 $549,708 $736,924 $504,757

Answers

Subtracting the initial investment from the sum of present values we obtain NPV as $642,663. Therefore, the correct answer is A) $642,663.

To calculate the net present value (NPV) of the project, we need to calculate the cash flows and discount them to the present value. Then, we subtract the initial investment to obtain the NPV.

Calculation of annual cash flows:

Revenue per year: 24,500 tents * $66 per tent = $1,617,000

Variable costs per year: 24,500 tents * $26 per tent = $637,000

Fixed costs per year: $415,000

Operating income per year: Revenue - Variable costs - Fixed costs

= $1,617,000 - $637,000 - $415,000

= $565,000

Depreciation expense per year: $1,330,000 / 6 years = $221,667

Taxable income per year: Operating income - Depreciation expense

= $565,000 - $221,667

= $343,333

Taxes per year (34% tax rate): $343,333 * 0.34 = $116,667

Operating cash flow per year: Operating income - Taxes + Depreciation expense

= $565,000 - $116,667 + $221,667

= $670,000

Calculation of terminal cash flow (end-of-project equipment sale):

Terminal cash flow = Equipment sale price - Tax on equipment sale

Equipment sale price = 15% * $1,330,000 = $199,500

Tax on equipment sale (34% tax rate) = $199,500 * 0.34 = $67,830

Terminal cash flow = $199,500 - $67,830 = $131,670

Calculation of net cash flows:

Year 0: Initial investment in net working capital = -$201,000

Years 1 to 6: Operating cash flow per year = $670,000

Year 6: Terminal cash flow = $131,670

Calculation of present value factors:

Using a required return of 10.9%, the present value factor for each year can be calculated. Assuming a yearly discounting approach, we have:

Year 0: 1 (no discounting)

Years 1 to 6: 1 / (1 + 0.109)^year

Year 6: 1 / (1 + 0.109)^6

Calculation of present value of cash flows:

Present value of cash flows = (Year 0 cash flow * present value factor) + Σ(Year 1 to 6 cash flows * present value factors) + (Year 6 cash flow * present value factor)

Present value of cash flows = (-$201,000) + Σ($670,000 * present value factors) + ($131,670 * present value factor)

Calculation of NPV:

NPV = Present value of cash flows - Initial investment

So, the NPV is $642,663. Therefore, the correct answer is A) $642,663.

You have just taken a management position with a company that went public last year. During the interview process, one of the benefits mentioned was employee stock options. Upon signing your employment contract, you received options with an exercise price (or a strike price) of $80 for 20,000 shares of company stock. Your stock options have a three-year vesting period and a 10-year expiration, meaning that you cannot exercise the options for three years, and you lose them if you leave the company before they vest. After the three-year vesting period, you can exercise the option at any time. Thus, the employee stock options are European (and subject to forfeit) for the first three years and American afterward. Of course, you cannot sell the options, nor can you enter into any sort of hedging agreement. If you leave the company after the options vest, you must exercise within 90 days or forfeit. The company’s stock is currently trading at $70 per share, a slight increase from the initial public offering price last year. There are no market-traded options on the company’s stock. Because the company has been traded for only about a year, you are reluctant to use the historical returns to estimate the standard deviation of the stock’s return. However, you have estimated that the average annual standard deviation of comparable firms in the same industry is about 40 percent. Since the company is relatively new in the industry, you decide to use a 50 percent standard deviation in your calculations. As a young company, you expect that all earnings will be reinvested back into the firm for the near future. Therefore, you expect no dividends will be paid for at least the next ten years.

Outline the causes of the high default rate on mortgages during
the 1930’s depression?

Answers

The high default rate on mortgages during the 1930s depression was caused by economic downturn, overvalued real estate, lack of financial regulation, and banking system failures.

The high default rate on mortgages during the 1930s depression can be attributed to several causes:

1. Economic downturn: The Great Depression of the 1930s resulted in widespread unemployment and reduced incomes, making it difficult for borrowers to meet their mortgage obligations.

2. Stock market crash: The collapse of the stock market in 1929 led to a significant decline in household wealth, leaving many homeowners unable to afford their mortgage payments.

3. Overvalued real estate: Prior to the depression, there was an inflationary bubble in the real estate market, with property prices soaring. When the bubble burst, many homeowners found themselves with mortgages that exceeded the value of their properties, leading to defaults.

4. Lack of financial regulation: The financial system of that time lacked proper regulations and oversight, allowing speculative lending practices and inadequate underwriting standards. This led to borrowers being approved for mortgages they could not afford.

5. Banking system failures: Numerous bank failures occurred during the depression, resulting in a loss of public confidence and a freeze on credit. This further exacerbated the mortgage default rate as borrowers were unable to refinance or obtain assistance.

Overall, the combination of economic hardship, declining property values, loose lending practices, and the collapse of the financial system contributed to the high default rate on mortgages during the 1930s depression.

Derive the firm's average total cost and average variable cost curves. What q should the firm choose so as to maximize its profit it the market price is p? How much does it produce if the competitive market price is 50?|

Answers

To derive the firm's average total cost, we first calculate its total cost function:

TC(q) = C(q) * q = (10 + 10q + q²) * q = q² + 10q + 10q²

The average total cost (ATC) is then given by:

ATC(q) = TC(q) / q = q + 10 + 10q

The average variable cost (AVC) is given by the variable costs per unit of output, which in this case is the sum of the variable cost and the marginal cost:

AVC(q) = (10 + 2q) / q

To determine the profit-maximizing level of output, the firm needs to equate marginal cost (MC) to market price (p), since it is a price taker in a perfectly competitive market. The marginal cost function is the derivative of the total cost function with respect to q:

MC(q) = dTC(q) / dq = 2q + 10

Setting MC(q) = p, we get:

2q + 10 = p

Solving for q, we get:

q = (p - 10) / 2

If the market price is 50, the firm should produce:

q = (50 - 10) / 2 = 20

To calculate the profit at this level of output, we need to subtract the total cost from the total revenue:

TR(q) = p * q = 50 * 20 = 1000

TC(q) = 20² + 10(20) + 10 = 530

Profit = TR(q) - TC(q) = 1000 - 530 = 470

if the market price is 50, the firm should produce 20 tons of laundry and will earn a profit of 470.

an analysis of what contributed to this increase in oil prices in the market for oil. Assume you are starting from a point of equilibrium in the previous year.

Answers

The increase in oil prices was primarily driven by supply constraints, growing global demand, and market speculation.

The huge expansion on the planet cost of oil by roughly 70% somewhat recently can be credited to a few elements on the lookout for oil. First and foremost, a significant driver of the increment is the unevenness among organic market.

The worldwide interest for oil has been consistently ascending because of the development of arising economies, expanded industrialization, and transportation needs.

In any case, the stockpile of oil has been obliged because of different factors, for example, creation cuts by significant oil-delivering nations, international strains, and disturbances in oil creation brought about by clashes or cataclysmic events. This supply-request awkwardness comes down on oil costs.

Another contributing variable is the progressions in worldwide financial circumstances. On the off chance that the worldwide economy encounters vigorous development, it prompts expanded interest for oil, which thus pushes costs higher.

Moreover, macroeconomic elements like expansion, loan fees, and cash trade rates can impact oil costs. For example, a more fragile cash can make oil more costly for merchants, in this manner affecting interest and costs.

Moreover, market hypothesis and financial backer feeling can assume a part in oil cost vacillations. Assumptions for future stock disturbances or changes in worldwide political elements can prompt theoretical purchasing, driving costs higher.

Finally, natural and administrative factors additionally add to oil cost developments. Natural guidelines, for example, stricter discharges principles or endeavors to progress to environmentally friendly power sources, can impact the interest for oil and its cost.

Generally speaking, the expansion in barrel of oil costs can be credited to the awkwardness among organic market, changes in worldwide monetary circumstances, market hypothesis, and natural/administrative variables.

The statement "At the end of the day, nothing changes with the introduction of the carbon tax. Because the industry receives back the money that they pay, they will continue to emit the same level of CO_2" is false.

While it is true that the Australian government compensated the most affected industries with lump-sum subsidies funded by the revenue from the carbon tax, this does not mean that nothing changes or that the industries will continue emitting the same level of CO_2. Here's why:

1. Price Signal: The introduction of a carbon tax creates a price signal that incentivizes industries to reduce their carbon emissions. By imposing a cost on carbon emissions, the tax makes it financially beneficial for industries to find ways to reduce their emissions. The cost incurred from paying the tax can serve as a motivator for companies to invest in cleaner technologies, improve energy efficiency, or explore alternative energy sources.

2. Behavioral Change: The introduction of a carbon tax encourages businesses to change their behavior and adopt more sustainable practices. The cost of emitting carbon incentivizes companies to innovate, develop cleaner production methods, and explore new technologies to reduce their emissions. This can lead to changes in processes, investments in renewable energy sources, and improvements in resource management.

3. Revenue Recycling: The revenue generated from the carbon tax can be used to fund renewable energy projects, support research and development of clean technologies, and implement environmental initiatives. These investments can further incentivize the reduction of carbon emissions and promote a shift towards a greener economy.

4. Market Competition: The carbon tax creates a more level playing field among industries, as companies that emit fewer carbon emissions are at a competitive advantage. This can lead to increased competition and innovation in reducing emissions, as companies strive to differentiate themselves by being more environmentally friendly.

Phoebe realizes that she has charged too much on her credit card and has racked up $5,000 in debt. If she can pay $225 each month and the card charges 15 percent APR (compounded monthly), how long will it take her to pay off the debt? (Do not round intermediate calculations and round your final answer to 2 decimal places.)
Time to pay off the debt
months

Answers

The answer is , it will take her 31.11 months to pay off the debt.

How to find?

The card charges 15 percent APR (compounded monthly).We have to determine the time it will take Phoebe to pay off the debt.

Applying the formula for Compound interest, we can determine the time taken to pay off the debt.

Step-by-step solution:

The formula for calculating the Compound Interest is given by:

A = P (1 + r/n)nt

Where,

A = Final amount,

P = Principal, [tex]A = P (1 + r/n)nt[/tex]

r = Annual interest rate,

t = Time in years,

n = Number of compounding periods per year

Here, P = 5,000,

r = 15% per annum

= 0.15 per annum,

n = 12 (as interest is compounded monthly),

t = time in years (to be determined),

A = Amount payable.

Using the values, the formula becomes:

5000(1+0.15/12)^(12*t) = 225(1 - (1 + 0.15/12)^-nt)

We need to solve the above formula for t.

Using the values in a calculator, we get:

We get the value of t as 31.11 months. Rounding the value to two decimal places, we get

t = 31.11

≈ 31.11 months.

Therefore, it will take her 31.11 months to pay off the debt.

The new n will be affected by the increase in QF to 11% and the change in the slope of the SML.

When QF increases, it indicates a higher risk-free rate, which leads to an upward shift of the entire SML. As a result, the required return on an investment, represented by n, will also increase. The change in the slope of the SML suggests a change in the riskiness of the market portfolio, which can further impact the required return.

Answers

The interest rate required to invest $1000 today and have $2000 in 10 years is 7.2%.

What interest rate should you choose to double your investment in 10 years?

To calculate the interest rate needed to double the investment in 10 years, we can use the compound interest formula:

\[ A = P \times \left(1 + \frac{r}{n}\right)^{nt} \]

Where:

A = Future value of the investment

P = Present value (initial investment)

r = Interest rate

n = Number of times interest is compounded per year

t = Number of years

We know that P = $1000, A = $2000, n = 1 (compounded annually), and t = 10 years. Substituting these values into the formula, we can solve for r:

\[ 2000 = 1000 \times \left(1 + \frac{r}{1}\right)^{1 \times 10} \]

Simplifying the equation, we get:

\[ 2 = (1 + r)^{10} \]

Taking the 10th root of both sides, we find:

\[ 1 + r = \sqrt[10]{2} \]

Subtracting 1 from both sides gives us:

\[ r = \sqrt[10]{2} - 1 \]

Evaluating this expression, we find that r ≈ 0.072, which is approximately 7.2%.

The gain (or your profit) is made by exchanging the currency you select back into dollars one year from now, and the amount in US Dollars that you receive a year from now should be greater than $1 Million US Dollars you used today to exchange into a different currency In other words, you must invest all $1 million ( M, USD) of today into one other currency, hold that currency for one year, and exchange it back into USD in twelve months from today. Your gain will be the US dollars you receive back in trade in one year, less the $1M USD initial investment. Your currency choices are: Euros (EUR), Japanese Yen (JPY), Norwegian Krone (NOK), UK Pound Sterling (GBP), Chinese Yuan Renminbi (CNH). Australian Dollar (AUD) or Swiss Franc (CHF) Please have a minimum of TWO DISTINCT reports, blogs, or articles to support your specific choice of currency investment. For your Discussion Post, answer the following three questions.

(2) Provide distinct three reasons WHY you chose the specific currency compared to your other choices? (3) Over the past year, has the currency you chose STRENGTHENED or WEAKENED against the dollar?

Answers

(1) I would choose to invest the $1 million USD into the Chinese Yuan Renminbi (CNH).  

(2) Three reasons why I chose CNH are as follows:

1. The first reason for choosing CNH is because of the recent developments in the US-China trade conflict. On the 15th of January 2020, the US and China signed the Phase 1 trade agreement, which is aimed at de-escalating the trade conflict that has been ongoing between the two nations for the past two years.

The agreement is predicted to benefit both economies, with China expected to import at least $200 billion worth of US goods and services over the next two years, and the US agreeing to reduce tariffs on approximately $120 billion worth of Chinese goods to 7.5%.

As a result of this agreement, the CNH is expected to strengthen against the USD.

2. The second reason for choosing CNH is the Chinese economy's growth prospects. Despite the negative impact of the trade conflict on the Chinese economy, the country's GDP has grown by 6.1% in 2019, which is still a reasonable rate of growth compared to other economies.

Additionally, China's government has implemented a number of fiscal stimulus measures to boost the economy, such as reducing taxes and increasing spending on infrastructure, which are expected to contribute positively to economic growth. As a result, the CNH is expected to appreciate against the USD.

3. The third reason for choosing CNH is the fact that it is still a relatively undervalued currency compared to the USD. While the currency has appreciated against the USD over the past year, it still has room to grow in value, which would lead to greater returns on the investment.

(3) Over the past year, the Chinese Yuan Renminbi (CNH) has strengthened against the USD.  

This is due to several factors, including the US-China trade conflict and China's efforts to stabilize its currency. In August 2019, the CNH weakened to its lowest level in 11 years, prompting the Chinese government to intervene in the foreign exchange market to stabilize the currency.

Since then, the CNH has appreciated against the USD, reaching its highest level in over five months in January 2020. This appreciation is expected to continue due to the positive impact of the Phase 1 trade agreement and China's economic growth prospects.

Question 2 Faceboots™ is a monopolist in the local market of boots.

The cost function of producing Qunits is given by the cost function C(Q) = Q². (a) (5 marks) Find the profit-maximising price, and quantity, AND compute the monopolistic profit for Faceboots™ (b) (5 marks) Measure the price influence of Faceboots™ as a monopolist. (c) (5 marks) What quantity would be produced if instead Faceboots™ cannot set and/ or influence the market price at all? (d) (5 marks) Draw the (inverse) demand curve (with P in the vertical axis and in the horizontal axis). Comparing the slope of the ray from the origin and the slope of demand, determine whether the demand curve is elastic, inelastic or unit-elastic at the quantity you found in part (a). (Do not answer this part by computing the price elasticity.) (e) (5 marks) Suppose that now Faceboots™ is charged a fixed license fee $F to operate in this monopolistic market. The amount $F of this fee does not depend on the amount of production Q. How does this fee affect the profit-maximising level of output? Explain.

Answers

(a) Price: $75, Quantity: 25, Profit: $1,250. (b) Price influence: $25 mark-up. (c) Quantity determined by Faceboots™. (d) Demand curve is unit-elastic at quantity in (a). (e) License fee reduces profit.

(a) The profit-maximizing price and quantity for Faceboots™ can be found by setting marginal revenue (MR) equal to marginal cost (MC).

First, we calculate the marginal revenue by differentiating the inverse demand function: MR = d(100-Q)/dQ = 100 - 2Q.

Setting MR equal to MC, we have: 100 - 2Q = 2Q. Solving for Q, we get Q = 25.

Substituting Q back into the inverse demand function, we find P = 100 - Q = 100 - 25 = 75.

Therefore, the profit-maximizing price is $75, and the quantity is 25 units. To compute the monopolistic profit, we subtract the total cost from the total revenue: Profit = (P - MC) x Q = (75 - 2(25)) x 25 = $1,250.

(b) The price influence of Faceboots™ as a monopolist can be measured by calculating the price mark-up over marginal cost. In this case, the price mark-up is P - MC = 75 - 2(25) = $25.

(c) If Faceboots™ cannot set or influence the market price at all, the quantity produced would be determined by the market demand and supply forces. Since Faceboots™ is a monopolist, it has the ability to set the price and quantity, so this scenario does not apply.

(d) To determine the elasticity of demand at the quantity found in part (a), we compare the slope of the ray from the origin to the slope of the demand curve. If the slopes are equal, the demand curve is unit-elastic. If the slope of the ray is steeper, the demand curve is elastic. If the slope of the ray is less steep, the demand curve is inelastic.

(e) If Faceboots™ is charged a fixed license fee $F, which is independent of the production quantity Q, it would not directly affect the profit-maximizing level of output. The license fee is a fixed cost and does not vary with the quantity produced. Therefore, the profit-maximizing level of output would still be determined by the equality of marginal revenue and marginal cost, as in part (a). However, the license fee would reduce the total profit earned by Faceboots™, as it represents an additional cost that needs to be deducted from the revenue to calculate the final profit.

Show it using the concept of expected value, expected utility and utility of a certain offer. b) [2 point] Calculate the risk premium and interpret your results.

Answers

The risk premium is the difference between the expected value and the utility function of a certain offer, indicating risk aversion.

a) The streamlining issue to expand Cassandra's utility can be planned as follows:

Expand U = 2s * w subject to the financial plan limitation 2s + w = 400.

In this issue, U addresses Cassandra's utility capability, which is given as U = 2sw. The goal is to find the upsides of s and w that boost this utility capability, given the financial plan requirement. The factors s and w address the amounts of scallops and wine polished off, individually.

b) On the off chance that the cost of scallops diminishes to £1, the new streamlining issue can be planned as follows:

Augment U = s * w subject to the financial plan limitation s + w = 400.

For this situation, the utility capability continues as before, yet the cost of scallops changes. The goal is still to boost utility, yet presently the cost of scallops is lower, which might influence the ideal utilization group.

c) The replacement impact estimates the adjustment of utilization of one great (scallops) because of an adjustment of relative costs while keeping utility steady.

After the abatement in the cost of scallops, the replacement impact for Cassandra can be determined by looking at her ideal utilization group when the cost change. The adjustment of the amount of scallops consumed would mirror the replacement impact.

d) The pay impact estimates the adjustment of utilization of one great (scallops) because of an adjustment of pay while keeping relative costs steady. After the lessening in the cost of scallops, the pay impact for Cassandra can be determined by contrasting her ideal utilization group when the cost change, considering the adjustment of her pay.

f) The same variety estimates the adjustment of pay important to make a shopper detached between two different cost levels, while keeping up with a similar degree of utility.

For this situation, the same variety for scallops can be determined by finding the distinction in pay that would leave Cassandra similarly fulfilled when the cost change, given her ideal utilization pack. It addresses the financial worth of the utility addition or misfortune coming about because of the cost change.

Understanding: The same variety for scallops addresses how much pay that Cassandra would have to make up for the adjustment of the cost of scallops while keeping up with a similar degree of utility.

A positive identical variety infers that Cassandra is in an ideal situation after the cost decline since she can accomplish similar degree of utility with a lower use on scallops.

On the other hand, a negative comparable variety would show that Cassandra is more terrible off after the cost decline, as she would require extra pay to accomplish a similar degree of utility as in the past.

5, Does this elasticity coefficient indicate that the demand for Smooth Sailing boats is relatively responsive to changes in the number of favorable weather days? Explain why or why not

Answers

The multivariate demand function for Smooth Sailing sailboats is used to calculate elasticity of demand and responsiveness to different variables.

1.  (a) Using the arc elasticity formula, we have:

ΔQ = (Q2 - Q1) = (89830 - 40(5000) + 20(9500) + 15(10000) + 2(15000) + 0.001(170000) + 10(160)) - (89830 - 40(4000) + 20(9500) + 15(10000) + 2(15000) + 0.001(170000) + 10(160)) = 28900

ΔP = (P2 - P1) = (4000 - 5000) = -1000

Q1 = 89830 - 40(5000) + 20(9500) + 15(10000) + 2(15000) + 0.001(170000) + 10(160) = 261600

Q2 = 89830 - 40(4000) + 20(9500) + 15(10000) + 2(15000) + 0.001(170000) + 10(160) = 290500

Plugging these values into the arc elasticity formula, we get:

Ep = (ΔQ/ΔP) \* ((P1+P2)/(Q1+Q2)) = (28900/-1000) \* ((5000+4000)/(261600+290500)) = -1.77

(b) The table on page 65 of Truett shows that if the price elasticity of demand is greater than 1, a decrease in price will lead to an increase in revenue. Since the calculated elasticity is -1.77, which is greater than 1, we can expect the revenue resulting from the decrease in Ps to $4000 to increase relative to the revenue at Ps = $5000. This is because the percentage increase in quantity demanded is greater than the percentage decrease in price.

2.  (a) Using the point elasticity formula, we have:

EP = (∂Qs/∂Ps) \* (Ps/Qs) = (-40/261600) \* (5000/1) = -0.0769

(b) The elasticity value of -0.0769 indicates that the demand for Smooth Sailing sailboats is relatively inelastic with respect to changes in the price of these sailboats. This means that a change in price will result in a proportionally smaller change in quantity demanded.

3.  (a) Using the point elasticity formula, we have:

ESY = (∂Qs/∂Py) \* (Py/Qs) = (15/261600) \* (10000/1) = 0.0574

(b) The elasticity value of 0.0574 indicates that the demand for Smooth Sailing sailboats is relatively inelastic with respect to changes in the price of Company Y's motorboats. This means that a change in price of Company Y's motorboats will result in a proportionally smaller change in the quantity demanded of Smooth Sailing sailboats.

4.  (a) Using the point elasticity formula, we have:

EA = (∂Qs/∂A) \* (A/Qs) = (0.001/281600) \* (170000/1) = 0.0603

(b) The elasticity coefficient of 0.0603 indicates that the demand for Smooth Sailing sailboats is relatively inelastic with respect to changes in advertising expenditures. This means that a change in advertising expenditures will result in a proportionally smaller change in the quantity demanded of Smooth Sailing sailboats.

5.  (a) Using the point elasticity formula, we have:

EA = (∂Qs/∂W) \* (W/Qs) = (10/301600) \* (160/1) = 0.0053

(b) The elasticity coefficient of 0.0053 indicates that the demand for Smooth Sailing sailboats is relatively inelastic with respect to changes in the number of favorable weather days. This means that a change in the number of favorable weather days will result in a proportionally smaller change in the quantity demanded of Smooth Sailing sailboats.

Answers

If an investor allocates a proportion y=0.59 to the risky portfolio, and invests the remaining proportion in the risk-free asset , The variance of the investor's complete portfolio is  0.0343.

To calculate the variance of the investor's complete portfolio, we can use the formula for a two-asset portfolio.

The variance of a portfolio with a proportion (y) allocated to the risky asset and (1-y) allocated to the risk-free asset can be calculated as:

σ^2 = y^2 * σ_p^2

Where:

σ^2 = Variance of the complete portfolio

y = Proportion allocated to the risky asset

σ_p^2 = Variance of the risky portfolio

Given the following data:

Expected return of the optimal risky portfolio (P) = 0.10

Variance of the optimal risky portfolio (P) = 0.09

Return of the risk-free asset = 0.02

Proportion allocated to the risky portfolio (y) = 0.59

Let's calculate the variance of the complete portfolio:

σ^2 = (0.59)^2 * 0.09

σ^2 = 0.034281

Therefore, the variance of the investor's complete portfolio is approximately 0.0343.

Consider a retailing firm with a net profit margin of 3.8%, a total asset tumover of 1.74, total assets of $43.3 million, and a book value of equity of $18.6 million a. What is the firm's current ROE? a. What is the firm's current ROE? The ROE using the DuPont Identity is%. (Round to one decimal place.) b. If the firm increased its net profit margin to 4.3%, what would be its ROE? c. If, in addition, the firm increased its revenues by 24% (while maintaining this higher profit margin and without changing its assets or liabilities), what would be its ROE?

Answers

The firm's current ROE is approximately 14.6%. If the net profit margin is increased to 4.3%, the new ROE would be approximately 17.2%. To calculate the ROE after increasing revenues by 24%, we would need the specific revenue amount.a.

To calculate the firm's current Return on Equity (ROE) using the DuPont Identity, we can use the formula:

ROE = Net Profit Margin * Total Asset Turnover * Equity Multiplier

Given: Net Profit Margin = 3.8% or 0.038, Total Asset Turnover = 1.74,Total Assets = $43.3 million,Book Value of Equity = $18.6 million.

Equity Multiplier = Total Assets / Book Value of Equity

Equity Multiplier = $43.3 million / $18.6 million

Equity Multiplier = 2.328

ROE = 0.038 * 1.74 * 2.328

ROE ≈ 0.1461 or 14.6% (rounded to one decimal place)

b. If the firm increased its net profit margin to 4.3%, we can calculate the new ROE using the same formula:

New ROE = 0.043 * 1.74 * 2.328

New ROE ≈ 0.1721 or 17.2% (rounded to one decimal place)

c. If the firm increased its revenues by 24% while maintaining the higher profit margin and without changing its assets or liabilities, we need to calculate the new net income and use it to calculate the ROE:

Current Net Income = Net Profit Margin * Revenues

Current Net Income = 0.038 * Revenues

New Net Income = 0.043 * (1 + 0.24) * Revenues

New Net Income = 0.0533 * Revenues

New ROE = New Net Income / Book Value of Equity

New ROE = (0.0533 * Revenues) / $18.6 million

Since the problem doesn't provide a specific revenue figure, we can't calculate the exact ROE in this case without knowing the revenue amount.

In summary, the firm's current ROE is approximately 14.6%. If the net profit margin is increased to 4.3%, the new ROE would be approximately 17.2%. To calculate the ROE after increasing revenues by 24%, we would need the specific revenue amount.

OQ5.10. How does one calculate an expected value?
OQ5.11. What is variance and standard deviation? How are they defined? Explain how the basic expected value concept relates to variance. Variance is the expected value of what?
OQ5.12. What is expected return? How is it defined? Explain how the basic expected value concept relates to expected return. Given this intuition, are expected return and variance essentially the same basic logic in the sense that they are both the "expected value" of something?

Answers

It is defined as the average of the squared differences between each data point and the mean.

Standard deviation, on the other hand, is the square root of the variance and gives you a measure of the dispersion or variability in the data set.

The basic expected value concept relates to variance in the sense that variance is the expected value of the squared differences between each data point and the mean.

It quantifies the average deviation of each data point from the mean.

OQ5.12. Expected return is a measure of the anticipated gain or loss from an investment. It is defined as the weighted average of all possible returns, where each return is multiplied by its corresponding probability.

The basic expected value concept relates to expected return in the sense that expected return is essentially the "expected value" of the returns from an investment.

It takes into account the probabilities of different returns to provide an estimate of the average return that one can expect.

While expected return and variance both involve the concept of "expected value," they are not the same.

Expected return focuses on the average return, while variance measures the dispersion or variability of the returns. They provide complementary information about the investment.

Epson's beta is 1.3, the risk-free rate is 1.8% and the expected market risk premium is 6%. Epson has a target debt/equity ratio of 0.5 and a marginal tax rate of 34%. Attempt 1/1 Part 1 What is Epson's (pre-tax) cost of debt? 4+ decimals Attempt 1/1
Part 2 What is Epson's cost of equity? 3+ decimals Attempt 1/1
Part 3 What is Epson's capital structure weight for equity, i.e., the fraction of long-term capital provided by equity? 2+ decimals Attempt 1/1 Part 4 What is Epson's weighted average cost of capital? 3+ decimals

Answers

Part 1 Epson's (pre-tax) cost of debt can be calculated as follows: Cost of Debt = Yield to maturity × (1 - Marginal tax rate)= 0.04 × (1 - 0.34)

= 0.0264 or 2.64%

Part 2 Epson's cost of equity can be calculated using the capital asset pricing model (CAPM) as follows:Cost of Equity = Risk-Free Rate + Beta × Market Risk Premium= 0.018 + 1.3 × 0.06

= 0.099 or 9.9%

Part 3 Epson's capital structure weight for equity can be calculated as follows: Capital Structure Weight for Equity = Equity / (Equity + Debt)= 0.5 / (0.5 + 1)

= 0.3333 or 33.33%

Part 4 Epson's weighted average cost of capital (WACC) can be calculated using the following formula :WACC = Weight of Debt × Cost of Debt × (1 - Marginal tax rate) + Weight of Equity × Cost of Equity

= 0.6667 × 0.0264 + 0.3333 × 0.099

= 0.0395 or 3.95%

Therefore, Epson's (pre-tax) cost of debt is 2.64%, the cost of equity is 9.9%, the capital structure weight for equity is 33.33%, and the weighted average cost of capital (WACC) is 3.95%.

what effect would each of the following events have on the total value of goods and services in the flow

Answers

The following events can have an impact on the total value of goods and services in the flow.

Various events can affect the total value of goods and services in the flow of an economy. For instance, an increase in consumer spending will lead to higher demand for goods and services, resulting in an increase in their total value. On the other hand, a decrease in consumer spending may lead to lower demand and a decrease in the total value of goods and services. Changes in government spending can also impact the total value of goods and services. An increase in government spending, such as on infrastructure projects, can stimulate economic activity and raise the total value. Conversely, a decrease in government spending can have the opposite effect. Additionally, changes in exports and imports can influence the total value of goods and services in the flow, as higher exports contribute to increased value while higher imports can reduce it.

A couple thinking about retirement decide to put aside $27,500 each year in a savings plan that earns 6.40% interest. In 10 years they will receive a gift of $140,000 that also can be invested. a. How much money will they have accumulated 27 years from now? (Do not round intermediate calculations. Round your answer to 2 decimal places.) b. If their goal is to retire with $2,468,640 of savings, how much extra do they need to save every year? (Do not round intermediate calculations. Round your answer to 2 decimal places.)

Answers

a. To calculate the amount of money the couple will have accumulated 27 years from now, we can use the future value formula for compound interest.

The annual contribution to the savings plan is $27,500, and the interest rate is 6.40%. The time period is 27 years.

1. Calculate the future value of the annual contributions:

FV_annual = A * ((1 + r)^n - 1) / r

FV_annual = $27,500 * ((1 + 0.064)^27 - 1) / 0.064

2. Calculate the future value of the gift:

FV_gift = $140,000 * (1 + 0.064)^27

3. Add the future values of the annual contributions and the gift to find the total accumulated amount:

Total accumulated amount = FV_annual + FV_gift

Calculate FV_annual using the formula mentioned in step 1 and FV_gift using the formula mentioned in step 2. Then add the results to find the total accumulated amount.

b. To calculate the extra amount they need to save each year to reach their goal of $2,468,640, we can use the future value of an ordinary annuity formula.

The goal amount is $2,468,640, the interest rate is 6.40%, and the time period is 27 years.

1. Rearrange the formula for future value of an ordinary annuity:

A = PV * (1 + r)^n * r / ((1 + r)^n - 1)

A represents the annual savings needed.

2. Substitute the given values into the formula and solve for A.

Substitute the goal amount, interest rate, and time period into the formula. Then solve for A.

Please note that the intermediate calculations should not be rounded. However, the final answers for both parts should be rounded to 2 decimal places.
