Simulation models and Monte Carlo simulation provide valuable tools for understanding complex systems, analyzing uncertainties, and supporting decision-making processes. Verification and validation play crucial roles in ensuring the accuracy and validity of simulation models.
1. Advantages and Limitations of Simulation Models:
Advantages:
- Flexibility: Simulation models allow for testing different scenarios and variables in a controlled environment, providing the flexibility to simulate complex real-world systems.
- Risk-Free: Simulations provide a risk-free environment to test and analyze potential outcomes without incurring the costs or consequences associated with real-world experimentation.
- Decision Support: Simulation models can aid decision-making by providing insights into the likely outcomes of different strategies or interventions.
- Performance Evaluation: Simulation models can be used to evaluate the performance of systems, processes, or designs, helping to identify bottlenecks, inefficiencies, or areas for improvement.
Limitations:
- Simplifications and Assumptions: Simulation models are based on simplifications and assumptions, which may not accurately capture the complexities of real-world systems. Results are only as reliable as the assumptions made in the model.
- Cost and Time: Developing and running simulation models can be time-consuming and costly, especially for large-scale systems. It requires skilled personnel, resources, and significant computational power.
- Uncertainty: Simulations are subject to uncertainties in input parameters and assumptions, which can impact the accuracy and reliability of the results. The outcomes are probabilistic rather than deterministic.
- Model Validation: Ensuring the accuracy and validity of simulation models can be challenging. Validating the model against real-world data or benchmarking it against known outcomes is crucial but can be difficult to achieve.
2. Monte Carlo Simulation:
Monte Carlo simulation is a statistical technique used to model and analyze uncertainties in a system or process by generating random samples from probability distributions. It is based on the principle of repeated random sampling to obtain a range of possible outcomes and estimate their probabilities.
Principles underlying Monte Carlo simulation:
- Random Sampling: Monte Carlo simulation involves randomly sampling input parameters from their probability distributions to represent the uncertainty in the model.
- Probability Distributions: Probability distributions are assigned to the input parameters based on available data or expert judgment, capturing the range of possible values.
- Numerical Computation: The simulation model computes the outcomes based on the sampled input parameters and the relationships defined in the model.
- Statistical Analysis: The simulated outcomes are analyzed using statistical techniques to estimate the probability distributions of the results and derive summary statistics.
Steps in applying Monte Carlo simulation:
1. Define the Problem: Clearly define the system or process to be simulated and identify the key input variables and their probability distributions.
2. Generate Random Samples: Randomly sample values from the probability distributions of the input variables.
3. Run the Simulation: Execute the simulation model using the sampled input values and record the resulting outcomes.
4. Analyze the Results: Analyze the collected outcomes using statistical methods to derive summary statistics, probability distributions, and other relevant metrics.
5. Interpret and Communicate Findings: Interpret the results, draw conclusions, and communicate the insights gained from the simulation analysis.
3. Verification and Validation in Simulation:
- Verification: Verification refers to the process of ensuring that a simulation model is implemented correctly and free from programming errors. It involves checking the model's equations, logic, and coding against a set of known conditions or test cases. Verification aims to confirm that the model behaves as intended and produces expected results.
- Validation: Validation involves assessing the accuracy and reliability of a simulation model in representing the real-world system it intends to simulate. It compares the model's outputs with observed or measured data from the real system or with known theoretical results. Validation aims to determine if the model is a good representation of the system and if it produces results that are within an acceptable range of accuracy.
Verification and validation are iterative processes that require continuous refinement and improvement of the simulation model. These processes help ensure that the model is reliable, credible, and fit for the intended purpose. Proper verification and validation increase confidence in

6. If Zain's sales increase by 10%, Zain's EBIT increases by 15%. If Zain's EBIT increases by 6% Zain's EPS increases by 17%. Zain's degree of operating leverage (DOL) and degree of total leverage (DTL) are closest to: (2 marks)
The degree of operating leverage (DOL) and degree of total leverage (DTL) for Zain can be calculated based on the given information.
The degree of operating leverage (DOL) measures the sensitivity of the company's operating income (EBIT) to changes in sales. It is calculated as the percentage change in EBIT divided by the percentage change in sales.
DOL = Percentage change in EBIT / Percentage change in sales
In this case, we are given that when Zain's sales increase by 10%, Zain's EBIT increases by 15%. Therefore, the DOL can be calculated as:
DOL = 15% / 10% = 1.5
The degree of total leverage (DTL) takes into account the effect of both operating income (EBIT) and financial leverage (EPS) on changes in sales. It is calculated as the product of the degree of operating leverage (DOL) and the degree of financial leverage (DFL).
DTL = DOL * DFL
We are also given that when Zain's EBIT increases by 6%, Zain's EPS increases by 17%. Therefore, the DFL can be calculated as:
DFL = Percentage change in EPS / Percentage change in EBIT
DFL = 17% / 6% = 2.83
Finally, we can calculate the DTL:
DTL = DOL * DFL = 1.5 * 2.83 ≈ 4.25
Therefore, Zain's degree of operating leverage (DOL) is approximately 1.5 and the degree of total leverage (DTL) is approximately 4.25.

An amount of P=$5.45 million last year is equivalent to F=$6.82 million now at an interest rate of (i=?): 25.137% DO 42.22% CO 20%.B 29.6%-A
To calculate the interest rate (i), we can use the formula for calculating the future value (F) of an investment based on the present value (P) and the interest rate per period (i):
F = P * (1 + i)
Given that P = $5.45 million and F = $6.82 million, we can rearrange the formula to solve for i:
i = (F / P) - 1
Substituting the values:
i = ($6.82 million / $5.45 million) - 1
i ≈ 1.25 - 1 = 0.25
So, the interest rate (i) is approximately 25%.

C lower the price level by more than 15%.
D lower the price level, but by less than 15%
Option D, "lower the price level, but by less than 15%," accurately reflects the expected outcome based on the quantity theory of money.
The quantity theory of money indicates that a 15% reduction in the money supply will, in the long run, lower the price level, but by less than 15%.
According to the quantity theory of money, there is a direct relationship between the money supply and the price level in an economy. When the money supply decreases, assuming other factors remain constant, there is less money available to purchase goods and services. This reduction in the money supply, over time, leads to a decrease in overall spending and a corresponding decrease in prices.
However, the decrease in the price level is generally expected to be less than the percentage reduction in the money supply. This is because the relationship between the money supply and prices is influenced by other factors such as changes in velocity of money, real output, and economic productivity.

if the monopoly is regulated by zero-profit pricing, what will be the dwl? a. 7.50 b. 12 c. 30 d. zero
If the monopoly is regulated by zero-profit pricing, then the deadweight loss (DWL) would be zero. This is because zero-profit pricing sets the price of a good or service equal to its marginal cost, which leads to an efficient allocation of resources.
In a perfectly competitive market, the equilibrium price and quantity are determined by the intersection of the market supply and demand curves. This results in a market price that is equal to the marginal cost of production, and there is no deadweight loss (DWL).In contrast, a monopoly has market power and can charge a price that exceeds its marginal cost.
This leads to a DWL, which represents the loss of social welfare that results from a less efficient allocation of resources. In the case of zero-profit pricing, the monopolist sets the price equal to its marginal cost, which is the same as the competitive price.

Explain the difference between an ethical and non-ethical consumer. If you were willing to be vaccinated, evaluate if the behavior and actions of the Pfizer CEO, Albert Bourla would have been a key consideration for you in your decision on which vaccine to take? Why?
The Pfizer vaccine is known to be safe and effective, and therefore, my decision on which vaccine to take would have been based on the availability and accessibility of the vaccine.
An ethical consumer is one who makes purchase decisions based on ethical considerations, such as the environmental impact of a product, the treatment of workers involved in the production process, and the use of sustainable and fair trade materials. In contrast, a non-ethical consumer is someone who is less concerned with these issues and may prioritize convenience or price when making purchases.
As a leader of a major pharmaceutical company, it is important that the CEO is committed to ethical behavior and values, and is transparent about the company's operations. If the CEO is willing to cut corners and put profits above the safety and well-being of consumers, it is likely that this culture would be reflected throughout the company.
Therefore, if Albert Bourla had been involved in any unethical behavior or actions, such as prioritizing profits over safety, I would have been less likely to choose the Pfizer vaccine. However, if he had demonstrated a commitment to ethical behavior and values, it would have given me greater confidence in the Pfizer vaccine.

Demand for a product would be elastic under which of the following situations?
a. More substitutes are available for the product
b. Few substitutes are available for the product
c. A larger fraction of consumer budget is spent on the product
d. A smaller fraction of consumer budget is spent on the product
e. Both (a) and (c) above
The demand for a product would be elastic under the situations where more substitutes are available for the product (a) and a larger fraction of the consumer budget is spent on the product (c). Therefore, the correct answer is (e) Both (a) and (c) above.
When more substitutes are available for a product, consumers have more options to choose from. This means that if the price of the product increases, consumers can easily switch to a substitute, resulting in a relatively large decrease in quantity demanded. This responsiveness to price changes indicates elastic demand.
Additionally, when a larger fraction of the consumer's budget is spent on a product, it means that the purchase of the product represents a significant portion of their overall spending. In such cases, consumers are likely to be more price-sensitive, as an increase in price would have a greater impact on their budget. Therefore, a small increase in price could lead to a relatively larger decrease in quantity demanded, reflecting elastic demand.
In summary, the demand for a product is likely to be elastic when there are more substitutes available for the product and when a larger fraction of the consumer budget is spent on the product. In these situations, consumers are more likely to respond to price changes by switching to substitutes or reducing their quantity demanded, indicating a higher degree of price elasticity.

Market demand is described as follows: at a price of $1,000 per gizmo, 25,000 units will be sold whereas at a price of $600, 30,000 will be sold. The only costs of production are the initial sunk costs of building a plant. Gizmo Co. has already invested in capacity to produce up to 25,000 units.
a. Suppose an entrant to this industry could capture 50 percent of the market if it invested in $10 million to construct a plant. Would the firm enter? Why or why not?
b. Suppose Gizmo could invest $5 mil- lion to expand its capacity to produce 40,000 gizmos. Would this strategy be a profitable way to deter entry?
Three examples are: setting a specific deadline, providing limited quantity, and offering exclusive bonuses or discounts.
To make the strategy "This offer is good for a limited time only" credible, firms or industries can employ different tactics. One approach is to set a specific deadline, clearly stating when the offer expires. Another way is to provide limited quantities, creating a sense of scarcity and urgency. Lastly, offering exclusive bonuses or discounts for a limited time can make the offer more enticing and credible.
In scenario (a), the potential entrant would consider the cost-benefit analysis. Since investing $10 million to capture only 50 percent of the market does not justify the cost, the firm would likely decide not to enter the industry.
In scenario (b), Gizmo Co. needs to evaluate the profitability of expanding its capacity to produce 40,000 gizmos. The decision depends on whether the additional sales generated from the expanded capacity can cover the $5 million investment. If the incremental revenue exceeds the investment cost, it would be a profitable way to deter entry. However, if the additional sales do not justify the investment, Gizmo Co. might not find it beneficial to pursue this strategy.

The initial valuation is an integer multiple of 5, as is , so all u, are also integer multiples of 6. With this model, you will eventually either go bankrupt or be acquired, whether you make investments or not. (a) Explain how to find an investment policy that maximizes your expected profit. (Profit is the payout, when and if the company is acquired, minus the total operat- ing cost, minus the total of any investments made.) And yes, we mean over infinite time, although any given realization will terminate in bankruptcy or acquisition in a finite number of periods. (b) Consider the instance of the problem with % = $10M, ax = $100M, P₁ = 0.60. Po = 0.50, = $10K, € = $400K, 6 = $2M. What is the optimal investment policy? Report the expected profit, the probabil- ity that the startup goes bankrupt, and the expected time until the startup goes bankrupt or is acquired, all under the optimal policy. Use Monte Carlo simulation with the optimal policy to give a histogram of the profit. Give 10 trajectories of valuation on the same plot.
Investment policy that maximizes the expected profitIn order to find an investment policy that maximizes your expected profit, the optimal policy can be used. This policy indicates the optimal investment decision at each time period based on the current state of the company.
One can calculate the value function for this model, and this gives us the expected profit that we would obtain when we follow the optimal policy. There is a recursive relationship between the value functions that can be used to compute them iteratively.
This algorithm is called value iteration and it finds the optimal policy at the same time as it computes the value function. Optimal investment policyIn the given instance, the optimal investment policy can be found by solving the Markov decision process.

Case: Levi’s strategic change and leadership (40 marks)
Chip Bergh became CEO of Levi's in 2011. He had the task of turning around a company suffering a decline in revenue of 29% from $6.8 billion in 1997 to $4.8 billion. Bergh brought Harmit Singh onboard as CFO to strategically partner for a transformation.
"When I got to Levi’s in January of 2013, Chip said to me: ‘I’ve got these strategic choices on a piece of paper, but we don't have a strategic blueprint, and we’re going to be talking to the board in six months. Harmit, I need your help to bring this strategy and build it into a road map.’" But "change doesn't happen overnight; it takes time," Harmit Singh says.
A major step was investing in accelerating the women's segment of the business. The company later decided to pursue an IPO and went public in 2019. Then the pandemic hit in 2020 and pummeled the retail industry. Bergh and Singh again worked on managing strategic change.
The company had to do much more than tweak its existing e-commerce business, which was losing money before COVID hit. The company had to invest in it, quickly and heavily. "It's now profitable because it is scaled so quickly," Bergh told Fortune in November.
In Q4 2021, Levi's earned net revenues of $1.7 billion, up 22% versus Q4 2020; up 7% compared to Q4 2019. In addition to ensuring the company survives financially, the pandemic was also a time of self-reflection, Singh says. "Even in the deepest of the troughs, I think good leaders have to start thinking about who you want to be," he says. "I've learned the importance of being empathetic as a leader."
"When I started in my career, the CFO role was about creating shareholder value," Harmit Singh, EVP and CFO of Levi Strauss & Co. said, "Today, it's about broader stakeholder value creation."
Singh’s strategic journey at the company started since he joined in 2013. "I like to be called a coach and not a boss because I like to give constructive feedback," Singh told about his leadership style. "I have a team of about 12 people. I would say none of them are doing the exact same job they started with because I like to move people around and give them a diversity of experience. That's what happened to me."
"For me, I put my responsibilities as an executive officer and a leader of the team at the forefront of my decision making," Singh explains. "I do recognize that I represent more than just my personal viewpoints when I speak publicly as leader of the company."
He says providing a forum for thoughtful discussion and debate is "a critical component" of a successful company and a leadership team. "It makes us sure that broad perspectives are considered," Singh says. He added, "I'm proud of the decisions that we as a leadership team have taken in leverage to protect the health and safety of our employees."
Questions: (each question 20 marks)
Please comment on Levi’s strategic response to the pandemic. Does Levi’s strategy fall into the prescriptive approach or emergent approach? How do you evaluate Levi’s strategic change? Please provide theoretical arguments and logical reasoning.
From a contingency perspective, please comment on the effectiveness of leadership in Levi’s strategic change. Does leadership play an essential role in the change process? Please provide theoretical arguments and logical reasoning.
Levi's strategic response to the pandemic can be seen as falling into the emergent approach. The company had to quickly adapt and invest in its e-commerce business to survive financially. They made significant changes to their existing operations and focused on scaling their online presence, which resulted in profitability.
Levi's strategic response to the pandemic aligns more closely with the emergent approach to strategy. The company had to react swiftly to the unexpected challenges posed by the pandemic, such as the decline in retail sales and the need to boost their e-commerce business. Their strategy evolved in response to the changing circumstances and market conditions. They invested heavily in their online operations and quickly scaled it up, leading to profitability. This demonstrates an adaptive and flexible approach to strategy, where decisions were made based on real-time information and the need to survive and thrive in the face of uncertainty.
From a contingency perspective, leadership played an essential role in Levi's strategic change. Chip Bergh and Harmit Singh provided the vision, direction, and guidance needed to navigate the company through the turbulent times. Their leadership style, characterized by constructive feedback, diversity of experience, and stakeholder value creation, created an environment that encouraged innovation and adaptation. By involving the leadership team in decision-making and fostering thoughtful discussions, they ensured that a variety of perspectives were considered, leading to more informed and effective strategic choices. Effective leadership is crucial in managing change because it sets the tone, motivates employees, and facilitates the alignment of efforts toward common goals. In the case of Levi's, the leadership's strategic acumen and ability to adapt contributed to the success of their change initiatives and the company's resilience in the face of the pandemic.

Lane Industries is considering three independent projects, each of which requires a $1.6 million investment. The estimated internal rate of return (IRR) and cost of capital for these projects are presented here:
Project H (high risk): Cost of capital = 12% IRR = 14%
Project M (medium risk): Cost of capital = 11% IRR = 9%
Project L (low risk): Cost of capital = 7% IRR = 8%
Note that the projects' costs of capital vary because the projects have different levels of risk. The company's optimal capital structure calls for 40% debt and 60% common equity, and it expects to have net income of $3,500,000. If Lane establishes its dividends from the residual dividend model, what will be its payout ratio? Round your answer to 2 decimal places.
_____________%
To determine Lane Industries' payout ratio, we need to calculate the total dividends paid out to common equity shareholders. The payout ratio is defined as the ratio of dividends to net income. Here's how we can calculate it:
Net Income = $3,500,000
Since the company follows the residual dividend model, it first covers its financing needs and then distributes the remaining funds as dividends. Given that the optimal capital structure is 40% debt and 60% common equity, we need to calculate the financing needs and subtract them from the net income.
Financing Needs = Total Investment - Equity Portion
= $1,600,000 - (0.60 * $1,600,000)
= $1,600,000 - $960,000
= $640,000
After covering the financing needs, the remaining funds are available for dividends:
Available Dividends = Net Income - Financing Needs
= $3,500,000 - $640,000
= $2,860,000
Now we can calculate the payout ratio:
Payout Ratio = Dividends / Net Income
= Available Dividends / Net Income
= $2,860,000 / $3,500,000
= 0.8171 (rounded to four decimal places)
Therefore, the payout ratio is 81.71%.

Fitting a model to 100% accuracy would mean significant over-fitting; the model would not perform well when faced with new data
D. Fitting a model to 100% accuracy would mean significant over-fitting; the model would not perform well when faced with new data.
Fitting a classification tree to 100% accuracy on the training data can indicate that the model has memorized the training set rather than learning general patterns.
This leads to overfitting, where the model becomes too specific to the training data and fails to generalize well to unseen data. When faced with new data, the overfitted model may perform poorly and struggle to make accurate predictions. It is essential to find the right balance between model complexity and accuracy to ensure good performance on unseen data. Regularization techniques and setting appropriate stopping criteria can help prevent overfitting and improve the model's generalization capabilities.

Discuss the three primary areas of tort law.
Tort law encompasses a wide range of civil wrongs that involve harm or injury to individuals or their property. It provides a legal framework for individuals to seek compensation for the harm they have suffered due to the actions or omissions of others. The three primary areas of tort law are:
1. Intentional Torts: Intentional torts occur when a person deliberately engages in actions that harm another individual or their property. Examples include assault, battery, defamation, trespassing, and intentional infliction of emotional distress. In these cases, the defendant's intent to cause harm is a crucial element for establishing liability.
2. Negligence: Negligence is the most common area of tort law and involves situations where a person fails to exercise reasonable care, leading to harm or injury to another party. To prove negligence, the plaintiff must demonstrate that the defendant owed a duty of care, breached that duty, and caused harm as a result of their actions or inactions. Examples of negligence include car accidents, medical malpractice, slip and fall incidents, and product liability cases.
3. Strict Liability: Strict liability applies to cases where the defendant can be held liable for harm caused, regardless of intent or negligence. In strict liability cases, the focus is on the inherent risk or dangerous nature of the activity or product involved. Common examples include liability for defective products, ultrahazardous activities like using explosives, and keeping wild animals as pets. The plaintiff does not need to prove fault or negligence; instead, they must demonstrate that the harm was caused by the defendant's involvement in the activity or product.
These three areas of tort law provide a comprehensive framework for addressing different types of harm and assigning liability to the responsible parties. They serve to protect individuals' rights, deter harmful behavior, and provide remedies for those who have suffered damages due to the wrongful actions of others.

Accounting for purchases:Hayes purchases an item of equipment on 1 February 2021 for £350,000.
The item has an estimated useful life of 10 years and an estimated residual value of £20,000. It is depreciated on a straight-line basis. According to the tax authority, tax allowances for this particular item can be claimed at 25% on a reducing-balance basis. The tax rate can be taken as 30%.In this case, the useful life of the equipment is 10 years. Therefore, the depreciation per year is:Depreciation = (Cost of equipment - residual value) / useful life= (£350,000 - £20,000) / 10 years= £33,000 per year.
The journal entry for the purchase of equipment by Hayes would be:DebitEquipment £350,000CreditCash/bank £350,000(Being the purchase of equipment by Hayes on 1 February 2021)Accounting for tax:According to the tax authority, tax allowances for this particular item can be claimed at 25% on a reducing-balance basis. The tax rate can be taken as 30%.Therefore, tax depreciation = 25% * £350,000 = £87,500.
The tax base is the cost of the asset minus the tax depreciation for the previous years. Since it is the first year, there is no tax depreciation in the previous year. Hence the tax base for the first year is the same as the cost of the asset. Therefore, the tax base for the first year = £350,000Income tax = tax base * tax rate= £350,000 * 30% = £105,000However, the estimated income tax liability for the year ended 31 January 2022 is £55,000.

Consider a labour market with labour demand and supply functions given by the following equations: LD = AW₁ LS = BWb a. What would you expect the signs of a and b to be? Plot each of these curves, and graphically show the equilibrium wage and employment level. b. Often, it is easier to work with logarithms. Show that the following is an alternative way to represent the above labour supply and demand equations: D = A' + aw (S = B' + bw where lowercase letters represent natural logs; that is, D = InLD, S = InLS, w = InW, and A' = InA and B' = InB. Graph these functions with 1 and won the axes. Algebraically, solve for the equilibrium wage and employment levels. Notice that a and b are labour demand and supply elasticities, respectively. c. The government is considering a proportional payroll tax, so that taxes are collected as a percentage of the wage, where the tax rate is denoted t. With a payroll tax, the effective cost of labour to the firm is, thus, (1+t) W. Use the approximation that (1 + t) = t, and solve for the new market wage, the take-home wage of workers, and employment. Explain how the share of the taxes paid for by the workers depends on the relative supply and demand elasticities. Using reasonable estimates of these elasticities, calculate the probable incidence of this payroll tax. How might your answer differ between the short and the long run? d. An alternative tax would have the workers pay an income tax of t percent on their wage income, effectively reducing their wage to (1 – t) W. Use the same approximation and logic as in part (c) and show that the level of employment and worker take-home pay will be the same as with a payroll tax with the same tax rate.
a. The signs of "a" and "b" in the labour demand and supply equations can be determined based on economic theory and empirical observations:
- "a" represents the elasticity of labour demand, which measures the responsiveness of labour demanded to changes in the wage. Generally, the elasticity of labour demand is expected to be negative, as an increase in the wage would typically lead to a decrease in the quantity of labour demanded by firms.
- "b" represents the elasticity of labour supply, which measures the responsiveness of labour supplied to changes in the wage. The elasticity of labour supply can vary depending on various factors such as the availability of alternative job opportunities, preferences for leisure, and the ease of entering or leaving the labour market. In general, the elasticity of labour supply is expected to be positive, as an increase in the wage would incentivize individuals to supply more labour.
b. Taking the natural logarithm of the labour demand and supply equations gives:
D = A' + aw
S = B' + bw
Where lowercase letters represent natural logs (ln) and A' = ln(A) and B' = ln(B).
By graphing these functions with "w" on the x-axis and "D" or "S" on the y-axis, we can determine their slopes (elasticities) and equilibrium values. The equilibrium occurs where the labour demand and supply curves intersect, indicating the equilibrium wage and employment level. Algebraically solving for the equilibrium wage and employment levels involves setting the labour demand and supply equations equal to each other and solving for "w" (the natural log of the wage).
c. With a proportional payroll tax, the effective cost of labour to the firm becomes (1 + t)W, where "t" is the tax rate. Using the approximation that (1 + t) ≈ t, we can rewrite the equation as:
(1 + t)W ≈ tW
Solving for the new market wage "W'":
W' = W - tW = (1 - t)W
The take-home wage of workers would be (1 - t) times the original wage, and the employment level would adjust based on the new wage rate and labour supply and demand elasticities.
The share of taxes paid for by the workers depends on the relative elasticities of labour supply and demand. If the supply elasticity is greater than the demand elasticity (b > a), workers bear a larger burden of the tax. Conversely, if the demand elasticity is greater than the supply elasticity (a > b), firms bear a larger burden of the tax.
In the short run, where the supply of labour is less elastic due to limited time for workers to adjust their skills or seek alternative employment, workers are likely to bear a larger share of the tax burden. In the long run, where workers have more flexibility to adjust their skills and labour supply, the burden may be shared more equally or shifted towards firms.
To calculate the probable incidence of the payroll tax, we would need specific values for the elasticities "a" and "b" which are not provided in the question.
d. With an income tax of t percent, the worker's wage is effectively reduced to (1 - t)W. Using the same approximation as in part (c), the level of employment and worker take-home pay will be the same as with a payroll tax with the same tax rate. The tax burden would depend on the relative elasticities of labour supply and demand, as explained in part (c).
Again, the specific incidence of the tax would depend on the elasticities of supply and demand, which are not provided in the question.
