In this exercise, we consider the auction market for art first introduced in Exercise 2.24. The variables in the data file ashcan_small that we will be concerned with are as follows: RHAMMER = the price at which a painting sold in thousands of dollars YEARS OLD- the time between completion of the painting and when it was sold INCHSQ = the size of the painting in square inches O Create a new variable INCHSQ10 INCHSQ/10 to express size in terms of tens of square inches. Only consider observations where the art was sold (SOLD = 1). a. Estimate the following log-linear equation and report the results: In(RHAMMER) =B₁ + B, YEARS OLD+B,INCHSQ10+e b. How much do paintings appreciate on a yearly basis? Find a 95% interval estimate for the expected percentage price increase per year. c. How much more valuable are large paintings? Using a 5% significance level, test the null hypothesis that painting an extra 10 square inches increases the value by 2% or less against the alternative that it increases the value by more than 2%. d. Add the variable INCHSQ10³ to the model and re-estimate. Report the results. Why would you consider adding this variable? e. Does adding this variable have much impact on the interval estimate in part (b)? f. Redo the hypothesis test in part (c) for art of the following sizes: (i) 50 square inches (sixth percentile). (ii) 250 square inches (approximately the median), and (iii) 900 square inches (97th percentile). What do you observe? g. Find a 95% interval estimate for the painting size that maximizes price. h. Find a 95% interval estimate for the expected price of a 75-year-old, 100-square-inch painting. (Use the estimator exp{E[In(RHAMMER YEARS OLD=75. INCHSQ10=10)]} and its stan- dard error.)

Question 4: What are the three major reasons for government intervention into a particular problem? Select a substantive issue/problem (e.g., social security, welfare, environment) and discuss why the
The three major reasons for government intervention into a particular problem are market failure, distributional concerns, and public goods provision.
Taking the example of environmental issues, government intervention is necessary to address externalities, ensure equitable distribution of resources, and provide public goods that benefit society as a whole.
Environmental issues, such as pollution and resource depletion, often require government intervention due to market failures. Market failures occur when the price mechanism and individual self-interest do not lead to efficient outcomes.
In the case of environmental problems, there are externalities, where the actions of individuals or businesses impose costs on society that are not reflected in market prices. Government intervention can correct these market failures through regulations, taxes, and incentives to reduce pollution and promote sustainable practices.
Distributional concerns are another reason for government intervention in environmental issues. The costs and benefits of environmental policies are not always evenly distributed among different groups in society.
Governments play a role in ensuring that the burden of environmental degradation and the benefits of environmental protection are distributed fairly, addressing issues of social equity and environmental justice.
Additionally, environmental issues often involve the provision of public goods. Public goods, such as clean air and water, biodiversity, and natural landscapes, have non-excludable and non-rivalrous characteristics, making it difficult for the private sector to provide them efficiently. Government intervention is necessary to ensure the provision and preservation of public goods that benefit society as a whole.
In conclusion, government intervention in environmental issues is driven by market failures, distributional concerns, and the need to provide public goods. By addressing externalities, promoting equitable distribution, and ensuring the provision of public goods, governments can effectively tackle environmental challenges and safeguard the well-being of society.

Complete this question by entering your answers in the tabs below. Required 1 Required 2 Required 3 Required 4 Given the new assumption in requirement 3, should the outside supplier's offer be accepted? Yes No
It would be advantageous to accept the offer and purchase the carburetors from the outside supplier. Given the new assumption in requirement 3, the outside supplier's offer should be accepted because the financial advantage of buying 20,000 carburetors from the outside supplier is $160,000.
In order to calculate the financial advantage/disadvantage of buying 20,000 carburetors from the outside supplier, we will calculate the total cost of making carburetors: Direct materials = $13 per unit × 20,000 units = $260,000 Direct labor = $11 per unit × 20,000 units = $220,000 Variable overhead = $4 per unit × 20,000 units = $80,000 Traceable fixed overhead = $6+ per unit × 20,000 units = $120,000 Allocated fixed overhead = $9 per unit × 20,000 units = $180,000 Total cost = $860,000 Cost per unit = $860,000 ÷ 20,000 = $43 per unit The financial advantage/disadvantage of buying carburetors from the outside supplier is calculated by subtracting the selling price from the total cost per unit: Total cost per unit $43 Selling price per unit - $36 Advantage/disadvantage per unit $7 Advantage/disadvantage per 20,000 units $140,000 Therefore, if the company has no alternative use for the facilities that are now being used to produce the carburetors, buying 20,000 carburetors from the outside supplier will result in a financial disadvantage of $140,000.
Since buying carburetors from the outside supplier will result in a financial disadvantage of $140,000, the outside supplier's offer should not be accepted. If carburetors are purchased, Troy Engines, Ltd. can use the freed capacity to launch a new product that will yield a segment margin of $200,000 per year. The financial advantage/disadvantage of buying 20,000 carburetors from the outside supplier can be calculated as follows: Advantage/disadvantage per unit = Selling price per unit - Total variable cost per unit Selling price per unit = $36 Total variable cost per unit = Direct materials per unit + Direct labor per unit + Variable manufacturing overhead per unit Direct materials per unit = $13 Direct labor per unit = $11 Variable overhead per unit = $4 Total variable cost per unit = $13 + $11 + $4 = $28 Advantage/disadvantage per unit = $36 - $28 = $8 Advantage/disadvantage per 20,000 units = $8 × 20,000 = $160,000 Since the financial advantage of buying 20,000 carburetors from the outside supplier is $160,000,

Question content area bottom
Part 1
The annual rate of return Kirk must earn on his investment to accumulate enough money to pay for the ring is
%.
(Round to two decimal places.)
Rounded to two decimal places, the annual rate of return Kirk needs to earn is 9.40%.
To solve this problem, we need to determine the annual rate of return Kirk must earn on his investment to accumulate enough money to pay for the ring.
Let's break down the information given:
Kirk currently has $4,433 to invest.
The cost of the ring will be $11,500 in 7 years.
Kirk wants to accumulate enough money to pay for the ring within 7 years.
To find the required annual rate of return, we can use the compound interest formula:
Future Value = Present Value × (1 + Rate)^Time
Here's how we can apply it to this scenario:
Present Value (P) = $4,433
Future Value (FV) = $11,500
Time (T) = 7 years
We need to solve for the Rate (R).
Rearranging the formula:
Rate = (FV / PV)^(1/T) - 1
Substituting the given values:
Rate = ($11,500 / $4,433)^(1/7) - 1
Calculating:
Rate ≈ 0.0940
Therefore, Kirk must earn an annual rate of return of approximately 9.40% on his investment to accumulate enough money to pay for the ring.
Rounded to two decimal places, the annual rate of return Kirk needs to earn is 9.40%.

3. Suppose that you are considering raising the price of coca-cola. What factors would you want to consider about coke to determine its elasticity? Would you recommend increasing the price? Why?
When considering raising the price of Coca-Cola, the factors that you want to consider are its elasticity. Elasticity is the change in quantity demanded of a product in response to a change in its price.
A product is elastic if the change in price causes a large change in the quantity demanded. The product is inelastic if a change in price has no significant effect on the quantity demanded. For Coca-Cola, the factors that need to be considered include the availability of substitute products. The presence of close substitutes increases the elasticity of the product. Consumers can easily switch to other products that offer the same satisfaction.
Suppose that there are many substitute products for Coca-Cola. In that case, a small increase in price is likely to lead to a large decrease in the quantity demanded as consumers can easily switch to other products with similar satisfaction. The brand loyalty of consumers is another factor to consider when determining the elasticity of Coca-Cola. The more loyal the consumers, the less elastic the product is.
In this scenario, a small increase in price is likely to have a small impact on the quantity demanded.The income level of consumers is another factor that needs to be considered. If Coca-Cola is a luxury good, then the product is elastic. This means that an increase in price will lead to a significant decrease in the quantity demanded.
This is because the product is likely to be elastic due to the availability of substitute products. A small increase in price is likely to lead to a large decrease in the quantity demanded, which would lead to reduced revenue for the company.

Addressing environmental policy problems presents various challenges and opportunities. Three specific issue areas in public lands management described by Steel et al. are rangeland/forest management, energy, and wildlife.
Rangeland/forest management: One challenge in rangeland and forest management is balancing competing interests such as grazing, timber production, and conservation. These lands face threats from overgrazing, invasive species, and wildfire risks. The opportunity lies in adopting sustainable land management practices, implementing effective grazing management plans, restoring ecosystems, and promoting biodiversity conservation.
Energy: The energy sector poses challenges related to balancing the demand for energy resources with environmental concerns. Extractive activities such as oil, gas, and mineral exploration can have detrimental impacts on ecosystems, water quality, and air pollution. However, transitioning towards renewable energy sources and promoting energy efficiency presents opportunities for mitigating climate change and reducing environmental impacts.
Wildlife: Wildlife management involves challenges such as protecting endangered species, managing wildlife habitats, and mitigating conflicts with human activities. Issues may include habitat loss, poaching, and human-wildlife conflicts. Opportunities lie in implementing conservation strategies, habitat restoration, and promoting sustainable wildlife tourism while considering the needs of local communities.
These issue areas share some common challenges, such as the need for stakeholder collaboration, scientific research, and policy coordination. They also require balancing economic development with environmental sustainability.

When a project is newly initiated, company has to first define the project and then prepare initial time and cost estimates. However, in real-world practice, the company may refine and adjust the initial time and cost estimates at the later stage. Discuss THREE reasons for refining the initial time and cost estimates. For each reason, provide one example to illustrate it. (12 marks)
When a project is newly initiated, the company has to first define the project and then prepare initial time and cost estimates. However, in real-world practice, the company may refine and adjust the initial time and cost estimates at a later stage.
Three reasons for refining the initial time and cost estimates are: Changes in scope of the project: The scope of the project can be modified at any point in time due to changes in market conditions or customer demand. It can also be modified due to changes in technology or regulation.
For example, if a new feature is required to be added in the software then it will increase the development time, which will increase the cost of the project.Change in resource availability: Resource availability can also change at any time. If a key resource is no longer available, the company may need to adjust the project timeline and budget. For example, if a project manager is not available to work on the project for a specific duration then the company will need to hire another project manager which will increase the cost of the project.Changes in project requirements: Changes in project requirements can also impact the project timeline and budget. This may occur when project stakeholders make changes to the requirements or when the company realizes that the requirements were not properly understood in the beginning. For example, if the client wants to add more features to the software which will increase the time required to develop the software then the cost of the project will also increase.

Identify 3 items in your life that are elastic.
Identify 3 items in your life that are inelastic.
Explain for each item why it is elastic or inelastic, using the
determinants of elasticity.
Elastic items:
1. Movie tickets: Movie tickets are typically considered elastic because they are not a necessity and there are many substitutes available. If the price of movie tickets increases, consumers can easily choose to watch movies at home, stream content online, or engage in other leisure activities. Additionally, consumers are usually sensitive to changes in movie ticket prices, and a small increase can significantly impact their decision to purchase.
2. Airline tickets: Airline tickets are generally elastic due to the presence of substitutes and the availability of different airlines. When the price of airline tickets increases, consumers may opt for alternative modes of transportation such as driving, taking a train, or even choosing a different destination. The price sensitivity is high, especially for leisure travelers who have the flexibility to adjust their plans based on price fluctuations.
3. Non-branded groceries: Non-branded groceries, such as generic or store-brand products, are often elastic. These items tend to have more substitutes available in the market, including other brands and private-label alternatives. Consumers can easily switch to different brands or store options if the price of non-branded groceries increases. Price changes can significantly impact consumers' purchasing decisions in this category.
Inelastic items:
1. Prescription medication: Prescription medication is typically considered inelastic because it is often a necessary and essential item for individuals with specific health conditions. The lack of close substitutes and the essential nature of the medication make consumers less price-sensitive. People rely on these medications for their health and well-being, and they are willing to pay the necessary price to obtain them.
2. Gasoline: Gasoline is generally considered inelastic due to its importance in daily transportation needs. Despite price fluctuations, consumers often have limited alternatives to gasoline for powering their vehicles. The demand for gasoline tends to be less responsive to price changes in the short term, as individuals need to fuel their cars to go about their daily activities.
3. Electricity: Electricity is another example of an inelastic item. It is a basic necessity in modern life, used for lighting, heating, cooling, and powering appliances. The lack of close substitutes and the essential nature of electricity make it less sensitive to price changes. Consumers have limited options for switching to alternative sources of power, especially in the short term.
In each case, the determinants of elasticity play a role in determining the elasticity or inelasticity of the items. Factors such as the availability of substitutes, the proportion of the budget spent on the item, and the necessity or luxury status of the item influence consumers' sensitivity to price changes and their ability to adjust their consumption patterns.

Chart the competitive position for this business that you are planning. b) Define the minimum viable business product for a technology-based platform solution that lets university students in Bangladesh borrow from and lend to each other (peer-to-peer lending business model).
a) Value proposition for vitamin-infused water business in Bangladesh Value proposition is the unique value that a company or product offers to its customers. b) Minimum viable product for peer-to-peer lending business model in Bangladesh.
If we were to create a new venture that sells vitamin-infused water in Bangladesh, then the value proposition would be that the product is a healthy beverage option that provides vitamins and minerals to consumers in a convenient and affordable way. The target audience would be health-conscious individuals who are looking for a refreshing drink that is beneficial to their health. To make the product stand out, the business could offer a variety of flavors and use natural ingredients. The competitive position for this business would be moderately high, as there is currently a trend towards healthier lifestyles and there is a demand for functional beverages in the market. However, there may be other established brands that offer similar products, so the business would need to differentiate itself through branding, pricing, and distribution strategy. The minimum viable product (MVP) is the simplest version of a product that can be released to the market to test its viability. For a technology-based platform solution that lets university students in Bangladesh borrow from and lend to each other (peer-to-peer lending business model), the MVP could be a basic website or mobile application that allows students to create profiles, view loan requests and offers, and make transactions. The platform could incorporate a system for verifying user identities, credit scores, and academic standing. The MVP would need to have a secure payment gateway, feedback system, and user support. The platform could generate revenue through transaction fees or interest rates. The MVP would be tested in a small group of early adopters before scaling up to a larger audience. The success of the MVP would depend on the willingness of students to use the platform, the efficiency of the platform's operation, and the viability of the business model.

In a BIP problem, which of the following constraints would enforce a mutually exclusive relationship between project 1 and project 2?
Multiple Choice
x1 + x2 ≤ 1
x1 + x2 ≥ 1
x1 − x2 ≤ 1
x1 − x2 = 1
None of the answer choices is correct.
The correct answer is x1 + x2 ≤ 1. This constraint ensures that either project 1 or project 2 can be selected, but not both at the same time. If x1 = 1 (project 1 is selected), then x2 must be 0 (project 2 is not selected) and vice versa.
The other constraints do not enforce this mutually exclusive relationship between the two projects. x1 + x2 ≥ 1 allows both projects to be selected at the same time, x1 − x2 ≤ 1 allows for overlapping selection of both projects, and x1 − x2 = 1 only enforces a specific difference between the selection of project 1 and project 2.

compute the expected return and standard deviation for an investment with the return of (-20%), 0%, 15%, 30% and 50% with respective following probabilities for the coming years : 20%, 20%, 30%, 20% and 10%
To compute the expected return and standard deviation, we will use the following formula:
Expected Return = (Return1 × Probability1) + (Return2 × Probability2) + ... + (Returnn × Probabilityn)
Standard Deviation = √[((Return1 - Expected Return)^2 × Probability1) + ((Return2 - Expected Return)^2 × Probability2) + ... + ((Returnn - Expected Return)^2 × Probabilityn)]
Given the returns and their respective probabilities:
Return: -20%, 0%, 15%, 30%, 50%
Probability: 20%, 20%, 30%, 20%, 10%
We can calculate the expected return as follows:
Expected Return = (-20% × 20%) + (0% × 20%) + (15% × 30%) + (30% × 20%) + (50% × 10%)
= -4% + 0% + 4.5% + 6% + 5%
= 11.5%
The expected return for the investment is 11.5%.
To calculate the standard deviation, we first calculate the deviations from the expected return for each return:
(-20% - 11.5%) = -31.5%
(0% - 11.5%) = -11.5%
(15% - 11.5%) = 3.5%
(30% - 11.5%) = 18.5%
(50% - 11.5%) = 38.5%
Next, we square these deviations and multiply them by their respective probabilities:
((-31.5%)^2 × 20%) + ((-11.5%)^2 × 20%) + ((3.5%)^2 × 30%) + ((18.5%)^2 × 20%) + ((38.5%)^2 × 10%)
Simplifying these calculations, we get:
Standard Deviation = √[(9.9225% × 20%) + (1.3225% × 20%) + (0.1225% × 30%) + (3.4225% × 20%) + (14.8225% × 10%)]
= √[1.9845% + 0.2645% + 0.0368% + 0.6845% + 1.48225%]
= √4.45255%
≈ 2.11%
The standard deviation for the investment is approximately 2.11%.
