In City of Inmates, Lytle-Hernandez discusses two laws that the US Congress passed that had detrimental affects upon different communities, the laws were specifically aimed as specific communities. Chapters 3 and 5 provide us with the stories of these laws that fulled incarceration. Discuss the similarities between the Geary Act of 1892, the 1924 Immigration Act, and Blease's Law of 1929 (the law is known by different names: Immigration Act of March 9, 1929 and the Undesirable Alien Act of 1929).
The Geary Act of 1892, the 1924 Immigration Act, and Blease's Law of 1929 are three laws that had significant detrimental effects upon particular communities. They were similar in many ways, and their purpose was to restrict specific communities to enter or stay in the country.
What was the purpose of the Geary Act of 1892?The Geary Act of 1892 was an amendment to the Chinese Exclusion Act of 1882. It mandated that all Chinese residents of the United States, including American-born citizens of Chinese origin, be registered and carry photo identification certificates.
The Act had the effect of lengthening the exclusion period and making the deportations and exclusion more extreme. The Act is comparable to the 1924 Immigration Act and Blease's Law of 1929 in terms of its goal of prohibiting immigrants and unwanted aliens from entering the country. The 1924 Immigration Act, commonly known as the Johnson-Reed Act, was a law enacted by Congress that established quotas for immigrants by country of birth.
The goal of the 1924 Immigration Act was to reduce the number of immigrants entering the United States, primarily targeting immigrants from Southern and Eastern Europe. The law also specified the number of immigrants who could enter the United States each year. The Immigration Act of 1924 targeted specific communities, much like the Geary Act. Blease's Law, which was passed in South Carolina in 1929, was similar in many ways to the two federal laws.
The law permitted law enforcement officials to deport undocumented people to Mexico without trial. It also included provisions for forced labor, particularly chain gangs. The law was intended to reduce crime, but it primarily targeted African Americans and other people of color.The Geary Act of 1892, the 1924 Immigration Act, and Blease's Law of 1929 were all examples of laws passed by Congress to restrict immigration and target specific communities.

The answer is indeterminate. Therefore, the correct answer is 'Indeterminate.'
The given consumption function is C = 250 + 0.75YD.
We are given that government spending increases by USD 100.
We have to determine how much the equilibrium output will increase by.
Government spending increasing by USD 100 means that G increases by USD 100.
Therefore, the new equation is
Y = C + I + G
= 250 + 0.75 (Y-T) + 1 + (G + 100).
Simplifying the equation:
Y = 250 + 0.75Y - 0.75T + 1 + G + 100 + I.
We know that I is an exogenous variable and T is not given, so we cannot determine the equilibrium output using the given information.

ABC Corporation wants to launch one of its mega campaigns to promote a special product The promotion budgets not yet finalized, but they know that some Rs.55,00,000 is available for advertising and promotion.
Management wants to know how much they should spend for television spots, which is the most appropriate medium for their product. They have created five T.V. campaign strategies' with their projected outcome to increase the sales. Find which one they have to select to yield maximum utility. The data required is given below:
Strategy Cost in 1000 of Rs. Increased in sales 1000 of Rs
A 1.80 1.78
B 2.00 2.02
C 2.25 2.42
D 2.75 2.68
E 3.20 3.24
To determine the most appropriate television campaign strategy that yields maximum utility for ABC Corporation, we need to compare the cost of each strategy with its projected increase in sales. The data provided is as follows:
Strategy A: Cost = Rs.1.80 million, Increase in sales = Rs.1.78 million
Strategy B: Cost = Rs.2.00 million, Increase in sales = Rs.2.02 million
Strategy C: Cost = Rs.2.25 million, Increase in sales = Rs.2.42 million
Strategy D: Cost = Rs.2.75 million, Increase in sales = Rs.2.68 million
Strategy E: Cost = Rs.3.20 million, Increase in sales = Rs.3.24 million
To calculate the utility, we can divide the increase in sales by the cost for each strategy:
Utility for Strategy A = 1.78 / 1.80 = 0.9889
Utility for Strategy B = 2.02 / 2.00 = 1.0100
Utility for Strategy C = 2.42 / 2.25 = 1.0756
Utility for Strategy D = 2.68 / 2.75 = 0.9733
Utility for Strategy E = 3.24 / 3.20 = 1.0125
Comparing the utilities, we find that Strategy C has the highest utility of 1.0756. Therefore, ABC Corporation should select Strategy C to yield maximum utility for their television campaign and promote their special product.

You borrowed an amount three years ago. The terms of the loan calls for an annual payment of $2,717.36 each year for 10 years. If the interest rate on the loan is 6%, what is the outstanding balance today?

14,568.22
Present Value (PV) of perpetuity that will pay $10,000 in one year and grow at 3% annually, if the discount rate is 10% is $133,333.33
The formula to calculate the PV of perpetuity is:
P = PMT / r Where,P = Present Value
PMT = Annual Payment
= Interest rate
PMT1 = PMT x (1 + g)
Where, PMT1 = Payment at the end of the year
2PMT = Payment at the end of the year
1g = Growth rateYear 1 Payment
= $10,000Year
2 Payment = $10,000 x (1 + 0.03)
= $10,300r
= 10%g
= 3%
So, Year 1 Payment = PMT
= $10,000
Year 2 Payment = PMT1
= $10,300r
= 10%g
= 3%
Plugging the values in the formula:
P = PMT / r + PMT1 / (r - g)
P = $10,000 / 0.10 + $10,300 / (0.10 - 0.03)P = $100,000 + $133,333.33P
= $233,333.33
Therefore, the present value of a perpetuity will pay $10,000 in one year and grow at 3% annually, if the discount rate is 10%. (first payment at the end of this year) is $133,333.33.The outstanding balance on a loan that calls for an annual payment of $2,717.36 each year for 10 years at an interest rate of 6%, which you borrowed an amount three years ago can be calculated using the PV formula.
The formula to calculate the present value of an annuity is:
PV = PMT x ((1 - (1 / (1 + r)ⁿ)) / r) Where, PV = Present Value
PMT = Payment per period
= Interest rate per period
= Total number of periods
First, we need to find the present value of the annuity. We can do that using the above formula as follows:
PV = $2,717.36 x ((1 - (1 / (1 + 0.06)¹⁰)) / 0.06)PV = $21,000.74
Now, we need to find the outstanding balance of the loan today, which will be the present value of the remaining payments. We can use the PV formula to calculate the present value of an annuity.
The formula for calculating the present value of an annuity due is:
PV = PMT x ((1 - (1 / (1 + r)ⁿ)) / r) x (1 + r)
Where, PV = Present Value
PMT = Payment per period
= Interest rate per period
= Total number of periodsFirst, we need to find the present value of the remaining annuity.
We can do that using the above formula as follows:
PV = $2,717.36 x ((1 - (1 / (1 + 0.06)⁷)) / 0.06) x (1 + 0.06)PV
= $14,805.77
Finally, we can subtract the present value of the remaining payments from the present value of the original loan to find the outstanding balance today.
Therefore, Outstanding balance today = Present value of the original loan - Present value of the remaining payments= $21,000.74 - $14,805.77= $6,194.97
Therefore, the outstanding balance today is $6,194.97.

Describe two ways in which the Pakistan’s government tries to encourage advances in technological knowledge.
Explain how higher saving leads to a higher standard of living through entrepreneurial activities. What are your suggestions for a policymaker in order to bring a change towards higher saving and entrepreneurial activities?
Research and Development (R&D) Funding: The government of Pakistan can encourage advances in technological knowledge by allocating a significant portion of its budget towards research and development.
By providing financial support to universities, research institutions, and private companies, the government can incentivize and facilitate scientific and technological advancements. This funding can be used for conducting research, developing new technologies, and promoting innovation in various sectors, such as information technology, biotechnology, renewable energy, and telecommunications.
Educational Initiatives: The government can promote technological knowledge by focusing on improving the quality of education, particularly in the fields of science, technology, engineering, and mathematics (STEM). By investing in educational infrastructure, curriculum development, and teacher training, the government can equip students with the necessary skills and knowledge to pursue careers in technology-related fields. Additionally, establishing partnerships between educational institutions and industry players can facilitate knowledge transfer, internships, and practical training opportunities, fostering a culture of technological innovation.
Higher saving leads to a higher standard of living through entrepreneurial activities because savings provide the necessary capital for investment, which fuels economic growth and innovation. When individuals and businesses save a portion of their income, it creates a pool of funds that can be used to finance new ventures, expand existing businesses, and support entrepreneurial activities. This, in turn, leads to job creation, increased productivity, and the development of new products and services, ultimately contributing to a higher standard of living for the population.
To encourage higher saving and entrepreneurial activities, policymakers can consider the following suggestions:
Implement Financial Education Programs: Launch educational initiatives to raise awareness about the importance of saving and investment. This can be done through schools, universities, public campaigns, and financial literacy programs. By enhancing people's financial knowledge and promoting a culture of saving, individuals may be more inclined to save a portion of their income and explore entrepreneurial opportunities.
Facilitate Access to Capital: Establish mechanisms to make capital more accessible to entrepreneurs and small businesses. This can include creating government-backed loan programs, venture capital funds, or grants targeted at startups and innovative projects. Policymakers can also collaborate with financial institutions to develop tailored financial products and services for entrepreneurs, such as low-interest loans, business mentoring programs, or crowdfunding platforms.
Streamline Regulations and Reduce Red Tape: Simplify bureaucratic procedures and regulatory requirements to make it easier for individuals and businesses to start and operate businesses. Reducing barriers to entry and creating a favorable business environment can encourage entrepreneurial activities and stimulate economic growth.
Foster Collaboration and Networking: Facilitate networking opportunities and collaboration among entrepreneurs, investors, and industry experts. Policymakers can organize conferences, workshops, and entrepreneurship forums where aspiring entrepreneurs can connect with potential investors, mentors, and business partners. Additionally, fostering collaboration between universities, research institutions, and businesses can encourage knowledge transfer and the commercialization of innovative ideas.
These suggestions can help create an environment conducive to higher saving and entrepreneurial activities, leading to economic growth, job creation, and an improved standard of living. However, it is important for policymakers to tailor their strategies based on the specific context and needs of the country.

Indexing a sum insured for term based on insured risk factors is a valuable tool for ensuring that insurance policies remain relevant and adequate over time, but it is typically only available for group insurance policies.
Indexing a sum insured for term refers to the adjustment of the policy's sum insured during its term to account for inflation or changes in the economic environment that affect the cost of replacing the insured's assets or paying the insured benefit. In other words, it's a way to ensure that the policy's sum insured remains relevant and adequate over time.Indexing the sum insured for term based on insured risk factors is typically only available for group insurance policies since the risk can be spread among a larger pool of individuals. This means that the insurer can make more accurate predictions about the risk level of the group as a whole, allowing for more accurate pricing and indexing of the sum insured. Group insurance policies can include life insurance, health insurance, and other types of insurance that are offered to a group of individuals, such as employees of a company.Individuals who wish to adjust the sum insured on their term life insurance policy based on inflation or other economic factors will need to request a new policy with a higher sum insured. This may involve going through the underwriting process again and may result in higher premiums if the insured's risk profile has changed since their initial policy was issued.For such more questions on Indexing

Question 3 The current disposable income of Joe is $90,000. Suppose that there is a 1 percent chance that his house may burn down, and if it does, the cost of repairing it will be $80,000, reducing his disposable income to $10,000. Suppose, too, that Joe’s utility function is
Uw=w
Where w is the initial wealth of the
(a) Would he be willing to spend $500 to purchase an insurance policy that fully insures him against his loss? (10 Marks)
(b) What is the highest price that he would be willing to pay for an insurance policy that fully insures him if his house burns down? (10 Marks)
Joe would not be willing to spend $500 to purchase an insurance policy that fully insures him against the loss and the highest price Joe would be willing to pay for the insurance policy is $495.
To determine whether Joe would be willing to spend $500 to purchase an insurance policy that fully insures him against the potential loss of his house, we need to compare the expected utility with and without the insurance.
(a) Without Insurance:
If Joe's house doesn't burn down, his disposable income remains $90,000, and his utility would be U(w) = U(90,000) = 90,000.
If Joe's house burns down (1% chance), his disposable income would reduce to $10,000, and his utility would be U(w) = U(10,000) = 10,000.
The expected utility without insurance is:
E(U) = (0.99 * U(90,000)) + (0.01 * U(10,000))
= (0.99 * 90,000) + (0.01 * 10,000)
= 89,100 + 100
= 89,200
(b) With Insurance:
If Joe purchases an insurance policy that fully insures him against the loss, he would pay $500 for the policy.
If Joe's house doesn't burn down, his disposable income would still be $90,000 - $500 (insurance premium) = $89,500, and his utility would be U(w) = U(89,500) = 89,500.
If Joe's house burns down (1% chance), the insurance policy covers the repair cost of $80,000, so his disposable income would still be $10,000, and his utility would be U(w) = U(10,000) = 10,000.
The expected utility with insurance is:
E(U) = (0.99 * U(89,500)) + (0.01 * U(10,000))
= (0.99 * 89,500) + (0.01 * 10,000)
= 88,605 + 100
= 88,705
Comparing the expected utilities, we can see that:
E(U) without insurance = 89,200
E(U) with insurance = 88,705
Since the expected utility without insurance (89,200) is higher than the expected utility with insurance (88,705), Joe would not be willing to spend $500 to purchase an insurance policy that fully insures him against the loss.
(b) The highest price Joe would be willing to pay for an insurance policy that fully insures him if his house burns down is determined by the difference in expected utilities between having insurance and not having insurance. In this case, the difference is 89,200 - 88,705 = 495.
Therefore, the highest price Joe would be willing to pay for the insurance policy is $495.

Since the production process of this component is quite simple and involves no capital investment, the Operations Manager proposes to make this component in house so that the component may flow gradually into the assembly line for use. The following data are also given for your comparison and decision making: To buy To make Annual demand 30,000 units 30,000 units Cost per unit $9 $10 Fixed cost $45 per order $72 per batch Holding cost (per unit per year) $2.7 $3.0 Weekly demand 600 units 600 units Weekly production N/A 800 units Lead time 5 days N/A Operates 50 weeks a year Suppose the company decides to continue to buy from the supplier. In which of the follow scenarios will EOQ decrease? The inventory holding cost increases from $2.7 to $3.0 The annual demand increases from 30,000 units to 60,000 units The fixed cost increases from $45 to $72 The cost per unit increases from $9 to $10 If the company decides to continue to buy from the supplier, which of the following is not true? If the fixed cost increases by a factor of 4, EOQ will increase by a factor of 2 If the annual demand and the inventory holding cost increase by a factor of 2, EOQ remains the same If the annual demand and the inventory holding cost increases by a factor of 2, the total annual cost remains the same If the fixed cost increases by a factor of 4, the total annual cost will increase by a factor of 2 Suppose the company decides to continue to buy from the supplier. If the lead time increases from 5 days to 10 days, the economic order quantity will Remain the same Decrease by a factor of 2 Increase by a factor of 4 Increase by a factor of v2 Increase by a factor of 2
To determine the scenarios in which the Economic Order Quantity will decrease, we need to consider the factors that affect EOQ. EOQ is calculated based on the trade-off between ordering costs and holding costs.
The formula for EOQ is: EOQ = sqrt((2 * annual demand * ordering cost) / holding cost)
If the inventory holding cost increases from $2.7 to $3.0, EOQ will increase because a higher holding cost implies higher costs associated with carrying inventory, which leads to larger order quantities.
If the annual demand increases from 30,000 units to 60,000 units, EOQ will increase because higher demand requires larger order quantities to meet the increased demand.
If the fixed cost increases from $45 to $72, EOQ will decrease because a higher fixed cost reduces the impact of ordering costs on the total cost, making smaller order quantities more economical.
If the cost per unit increases from $9 to $10, EOQ will remain unchanged because the cost per unit does not directly impact the trade-off between ordering costs and holding costs.
Considering the statements regarding the company's decision to continue buying from the supplier:
If the fixed cost increases by a factor of 4, EOQ will increase by a factor of 2.
If the annual demand and the inventory holding cost increase by a factor of 2, EOQ remains the same.
If the annual demand and the inventory holding cost increase by a factor of 2, the total annual cost remains the same.
If the fixed cost increases by a factor of 4, the total annual cost will increase by a factor of 2.
Lastly, if the lead time increases from 5 days to 10 days, the EOQ will remain the same because lead time does not directly impact the trade-off between ordering costs and holding costs.
In summary, the scenarios in which EOQ will decrease are when the fixed cost increases from $45 to $72.

The city government is considering two tax proposals:
A lump-sum tax $300 of on each producer of hamburgers.
A tax of $1 per burger, paid by producers of hamburgers.
Which of the following curves—average fixed cost, average variable cost, average total cost, and marginal cost—would shift as a result of the lump-sum tax? Why? Show this in a graph. Label the graph as precisely as possible.
The lump-sum tax does not impact the cost curves directly, but it adds a fixed cost component to the total cost structure, which can be represented as a horizontal line on the graph at the level of the tax amount.
The lump-sum tax of $300 on each producer of hamburgers would not directly impact any of the cost curves (average fixed cost, average variable cost, average total cost, and marginal cost). This is because a lump-sum tax is a fixed cost that does not change with the level of production or the number of burgers produced.
To illustrate this on a graph, we can consider a typical cost curve diagram with quantity produced (burgers) on the x-axis and cost on the y-axis. Let's assume we have the average variable cost (AVC), average total cost (ATC), and marginal cost (MC) curves plotted.
The AVC, ATC, and MC curves would remain unchanged with the introduction of a lump-sum tax. They would retain their original shapes and positions on the graph. The lump-sum tax of $300 is a fixed cost that does not vary with the level of production or the number of burgers produced. Therefore, it does not affect the per-unit costs represented by these curves.
However, we can represent the lump-sum tax on the graph as a horizontal line at the cost level of $300, intersecting the y-axis. This line would be parallel to the x-axis and would not have any slope since it does not change with the quantity produced. This represents the fixed cost component of the tax.

An economy is in equilibrium. Find Marginal Propensity to Consume from the following: National Income = 2000 Autonomous Consumption = 400 Investment Expenditure = 200 (2)
The Marginal Propensity to Consume (MPC) is the change in consumption spending divided by the change in disposable income. In simpler words, it is the proportion of additional income that consumers spend on consumption.
We can find the MPC from the given data as follows:Equilibrium in the economy is when aggregate demand equals aggregate supply. total spending equals total income.
We have:Total spending = National Income = 2000Total spending = C + I + G + NX where C = Consumption, I = Investment Expenditure, G = Government Spending, and NX = Net Exports.
Since the economy is in equilibrium, we have:2000 = C + 200 + G + NXWe know that Autonomous Consumption is that part of consumption spending which is independent of income.
In other words, it is the minimum level of consumption that is necessary to support life. So, we have:C = Autonomous Consumption + MPC × YDwhere YD = Disposable Income = National Income – Taxes – TransfersSince there is no information given about Taxes and Transfers, we can assume them to be zero for simplicity.
So, we have:2000 = (Autonomous Consumption + MPC × YD) + 200Substituting YD = National Income – Taxes – Transfers = 2000 – 0 – 0 = 2000, we get:2000 = (Autonomous Consumption + MPC × 2000) + 200Simplifying the above equation, we get:MPC = (2000 − Autonomous Consumption − 200) ÷ 2000= (2000 − 400 − 200) ÷ 2000= 1400 ÷ 2000= 0.7.
Therefore, the Marginal Propensity to Consume is 0.7, i.e., consumers spend 70% of any additional income on consumption spending.

A payroll-deduction plan is considered to be an ordinary annuity.
The employee should have $40,442.58 in the account in 10 years when he contributes $250 per month with an average of 3% per year compounded monthly.
Employee B has the opportunity to contribute to a payroll deduction 401(k) plan at work. This employee selects an option that averages 3% per year compounded monthly and contributes $250 per month.
Given that, Annual interest rate = 3%Compounding period = Monthly (12 per year)Time period = 10 yearsMonthly contribution (PMT) = $250
Number of payments (n) = 12 × 10 = 120
Using the formula to calculate future value of an ordinary annuity:FV = PMT × [(1 + i)n – 1] / iwhere, i = (1 + r/m)m/m – 1 and r is the annual interest rate divided by the compounding periods per year.
Substituting the given values, we get:FV = 250 × [(1 + 0.03/12)120 – 1] / (0.03/12)FV = $40,442.58

One purpose of a database system is the easy sharing of data. But this ease of sharing can also jeopardize security. Please discuss at least three forms of access control designed to reduce this risk
Access control is an essential aspect of database security, aimed at controlling and limiting user access to data.
Here are three forms of access control designed to reduce the risk associated with easy data sharing:
1. Authentication and Authorization:Authentication verifies the identity of users attempting to access the database system. It ensures that only authorized individuals can log in. This process typically involves usernames and passwords, multi-factor authentication, or biometric identification. Once authenticated, users are granted specific privileges based on their roles and responsibilities, which are defined through authorization mechanisms. Authorization ensures that users can only access the data and perform operations relevant to their authorized tasks, preventing unauthorized access and potential data breaches.
2. Role-Based Access Control (RBAC):
RBAC is a method of access control that assigns permissions and privileges based on predefined roles within an organization. Instead of assigning permissions to individual users, RBAC groups users into roles based on their job functions. Permissions and access rights are then assigned to these roles, simplifying administration and ensuring that users have the necessary access privileges to perform their duties. RBAC reduces the risk of data exposure by enforcing the principle of least privilege, where users are granted only the minimum permissions required to fulfill their tasks.
3. Encryption and Data Masking:Encryption and data masking techniques are used to protect the confidentiality of sensitive data in a database. Encryption transforms data into an unreadable format using encryption algorithms. Access to the encrypted data is granted only to authorized parties with the appropriate decryption keys. Data masking, on the other hand, involves replacing sensitive data with fictional or altered values to hide the original information while maintaining data integrity. Encryption and data masking provide an additional layer of security, ensuring that even if unauthorized individuals gain access to the database, the data remains protected and unusable.
By implementing these forms of access control, database systems can mitigate the risks associated with easy data sharing. They help maintain the confidentiality, integrity, and availability of data while ensuring that only authorized individuals can access and manipulate the data in a controlled and secure manner.

(i) To find the stationary values of K and L, we need to minimize the cost function subject to the production function constraint.
The cost function (C) is given by:
C = 2L + K
The production function (Q) is given by:
Q = K² + L²
The budget constraint is:
C = 10
We can rewrite the cost function as:
C = 2L + K = 10
Rearranging the cost function, we get:
K = 10 - 2L
Substituting this value of K into the production function, we have:
Q = (10 - 2L)² + L²
Q = 100 - 40L + 4L² + L²
Q = 5L² - 40L + 100
To find the stationary values of K and L, we need to take the first derivative of the production function with respect to L and set it equal to zero:
dQ/dL = 10L - 40 = 0
Solving this equation, we find L = 4.
Substituting the value of L back into the cost function, we can find the corresponding value of K:
K = 10 - 2L = 10 - 2(4) = 2
Therefore, the stationary values of K and L are K = 2 and L = 4.
To show the optimum points of K and L, we can plot the isoquant and isocost curves:
Isoquant curve: A curve representing different combinations of capital (K) and labor (L) that produce the same level of output (Q). In this case, the production function is Q = K² + L², so we have Q = 2² + 4² = 4 + 16 = 20. Thus, the isoquant curve is Q = 20.
Isocost curve: A curve representing different combinations of K and L that result in the same total cost (C). The cost function is C = 2L + K = 10, so we can rewrite it as L = (10 - K) / 2. Plotting the isocost curve, we can choose some values of K and calculate the corresponding L values:
K = 0, L = (10 - 0) / 2 = 5
K = 2, L = (10 - 2) / 2 = 4
K = 4, L = (10 - 4) / 2 = 3
K = 6, L = (10 - 6) / 2 = 2
K = 8, L = (10 - 8) / 2 = 1
We can now plot the isoquant curve Q = 20 and the isocost curve L = (10 - K) / 2 on a graph to determine the optimum points of K and L.
(ii) To evaluate the second-order conditions, we need to calculate the second partial derivatives of the production function with respect to K and L:
d²Q/dK² = 0 (second partial derivative with respect to K)
d²Q/dL² = 10 (second partial derivative with respect to L)
d²Q/dKdL = 0 (second partial derivative with respect to K and L)
The second-order conditions for a maximum require that:
d²Q/dK² < 0 (concave function in the K direction)
d²Q/dL² < 0 (concave function in the L direction)
(d²Q/dK²)(d²Q/dL²) - (d²Q/dKdL)² > 0 (negative determinant of the Hessian matrix)
In this case, d²Q/dK² = 0, d²Q/dL² = 10, and d²Q/dKdL = 0, so the second-order conditions are not satisfied. The Hessian determinant is equal to zero, which means we cannot determine whether the stationary values of K and L correspond to a maximum or a minimum without further analysis.
(b)
(i) To find the profit-maximizing level of price and outputs for each product, we need to maximize the profit function.
The profit function (π) is given by:
π = (P₁ - TC₁) * Q₁ + (P₂ - TC₂) * Q₂
The demand functions are:
Q₁ = 25 - 0.5P₁
Q₂ = 30 - P₂
The total cost function is:
TC = Q + 20Q₁ + 20Q₂
Substituting the demand and cost functions into the profit function, we have:
π = (P₁ - (Q + 20Q₁ + 20Q₂)) * (25 - 0.5P₁) + (P₂ - (Q + 20Q₁ + 20Q₂)) * (30 - P₂)
To find the profit-maximizing level of price and outputs, we need to take the first derivative of the profit function with respect to P₁, P₂, Q₁, and Q₂ and set them equal to zero:
∂π/∂P₁ = 25 - Q - 20Q₂ - 1.5P₁ = 0
∂π/∂P₂ = 30 - Q - 20Q₁ - 2P₂ = 0
∂π/∂Q₁ = P₁ - 25 + 0.5P₁ = 0
∂π/∂Q₂ = P₂ - 30 + P₂ = 0
Solving these equations simultaneously will give us the profit-maximizing level of price and outputs for each product.
(ii) To show that the second-order conditions for maximum profit are satisfied, we need to calculate the second partial derivatives of the profit function with respect to P₁, P₂, Q₁, and Q₂:
∂²π/∂P₁² = -1.5 (second partial derivative with respect to P₁)
∂²π/∂P₂² = -2 (second partial derivative with respect to P₂)
∂²π/∂Q₁² = 0 (second partial derivative with respect to Q₁)
∂²π/∂Q₂² = 0 (second partial derivative with respect to Q₂)
The second-order conditions for maximum profit require that:
∂²π/∂P₁² < 0 (concave function in the P₁ direction)
∂²π/∂P₂² < 0 (concave function in the P₂ direction)
∂²π/∂Q₁² > 0 (convex function in the Q₁ direction)
∂²π/∂Q₂² > 0 (convex function in the Q₂ direction)
In this case, ∂²π/∂P₁² = -1.5, ∂²π/∂P₂² = -2, ∂²π/∂Q₁² = 0, and ∂²π/∂Q₂² = 0. Therefore, the second-order conditions for maximum profit are not satisfied.
