Econ1025 Assessment Task 3 Case Analyses Sim Semester 1 2021 Pag ✓ Solved
ECON1025, Assessment Task 3: Case Analyses (SIM), Semester 1 2021 Page 1 of 1 RMIT Classification: Trusted Assessment Task 3: Case Analyses Answer any FOUR of the following questions. Each question is worth a total of 12.5 marks. If more than four questions are answered, marks will be awarded for the first four answers only. QUESTION 1 A “generic drug†contains the same active chemical ingredient as a drug that was previously protected by a patent. Generic drugs are essentially the same and are sold by many different, small firms after the original patent has expired.
A well-known example is the antibiotic penicillin. The COVID-19 pandemic has seen high use of penicillin by those infected by the virus. Using the demand-supply model, analyse this change in consumer preferences regarding this drug. Examine the likely consequences in one or two related markets of your choice. QUESTION 2 Penicillin is ineffective against the coronavirus.
In general, inappropriate use of penicillin, where it cannot alleviate symptoms or cure a disease, is contributing to antibiotic resistance, meaning bacteria are evolving to defeat the drug. This is endangering lives because of a rise in untreatable infections. Use the theories of market failure and government intervention to explain (i) why both patients and their prescribing physicians are failing to reduce the inappropriate consumption of penicillin, and (ii) what suitable government interventions may help this situation. Critically discuss potential problems with these interventions. QUESTION 3 Another solution for antibiotic resistance is the development of new drugs that defeat resistant bacteria.
Such research and development has a high fixed cost and can only be undertaken in industries with high market concentration where firms have significant monopoly power, like the pharmaceutical industry. Examine this industry using the theory and models of industry structure. Should government be worried about any aspect of how an industry with this market structure will perform? QUESTION 4 Pfizer is one of the world’s largest pharmaceutical companies. When developing a new drug this company needs to consider vertical integration.
Using the theory of the optimal boundary of the firm, discuss Pfizer’s make-or-buy decision for developing and producing a new antibiotic drug. What stages of the vertical chain should Pfizer consider conducting inhouse, and which should be outsourced? Provide reasons for your findings. QUESTION 5 Pfizer and a competitor, Astra-Zeneca, are considering developing a new drug for a particular illness at the same time. The illness is relatively rare but the fixed cost of production is very high.
In particular, the forecast demand for such a drug is insufficient to cover both firms’ costs. Analyse the interaction between the two firms using game theory. Present a payoff matrix to model the situation and analyse it for Nash equilibrium. What can either of these firms do to make their best, most- preferred outcome more likely? [END OF PAPER] 1 Binary Linear Optimization Analysis When we perform a linear optimization analysis, if the value of decision variables can only be either 0 or 1, we call this analysis a binary linear optimization analysis. A binary linear optimization analysis consists of four major steps: (1) identify the objective variable and decision variables; (2) create the objective function; (3) find out the constraints; (4) specify the decision variables to be binary.
I use an example to show everyone how we use this technique in a logistics analysis process. Example: An online shopping website plans to build distribution centers to serve customers from 20 counties as shown in the picture below. Each distribution center should serve customers either from the county OR from the adjacent counties. What is the minimum number of distribution centers needed to cover all 20 counties? 2 To simply the analysis, we give each county an id number.
For instance, 1 represents Ashtabula county; 2 represents Lake county, etc. (1) Identify the objective variable and decision variables Objective variable: Total number of distribution centers needed to serve these 20 counties. We use N to denote this number. Decision variables: To calculate the objective variable, we need to count how many counties have distribution centers. There are two possibilities in each county: It either has a distribution center OR not has one. Let ð‘¥ð‘– : the number of distribution center in a county; i: the id number of each county, i ∈ {1, 2, 3, …., 20} Thus, ð‘¥ð‘– = 1 if there is a distribution center in a county; otherwise, ð‘¥ð‘– = 0 for that county.
For instance, in Ashtabula county (county id i = 1), ð‘¥1 = 1 if Ashtabula county has a distribution center; ð‘¥1 = 0 if Ashtabula county does not have a distribution center. In Lake county (county id i = 2), ð‘¥2 = 1 if Lake county has a distribution center; ð‘¥2 = 0 if Lake county does not have a distribution center, etc. (2) Create the objective function N = ð‘¥1 + ð‘¥2 + ⋯ + ð‘¥20 Our objective is to minimize N (3) Find out the constraints The constraint in this case is that each distribution center must serve customers either from the county OR from the adjacent counties. Because we don’t know which counties would have the distribution centers yet, we should build the constraint for each county.
For instance, for Ashtabula county, it is adjacent to Lake county, Geauga county, and Trumbull county, as shown in the map on page 1. No matter where the distribution center is finally built among these counties, there must be at least one that serves Ashtabula county. Thus, the constraint for Ashtabula county is ð‘¥1 + ð‘¥2 + ð‘¥12 + ð‘¥16 ≥ 1 We should establish such a constraint for each county. For instance, for Lake county, it is adjacent to Ashtabula county, Cuyahoga county, and Geauga county. Thus, the constraint for Lake county is ð‘¥1 + ð‘¥2 + ð‘¥3 + ð‘¥12 ≥ For some counties that are adjacent to several other counties, the constraint could be stricter.
For instance, for Geauga county, it is adjacent to 6 counties (Ashtabula, Lake, Cuyahoga, Summit, Portage, and Trumbull), we have ð‘¥1 + ð‘¥2 + ð‘¥3 + ð‘¥10 + ð‘¥12 +ð‘¥13 +ð‘¥16 ≥ 1 In other words, no matter where the distribution centers are finally built, there must be at least one that serves the Geauga county. Using Solver (1) Open the source data file “Binary in Logistic Management.xlsx†In the data set, we first build a 20 by 20 matrix to indicate the counties locations in a mathematical way. We mark 1 if two counties share a border (i.e., adjacent geographically). We mark 0 if two counties do not share a border. (2) Objective and Decision variables We use cells from C32 to V32 to contain the decision variables.
If there is a distribution center in a county, the value for the decision variable will be 1; otherwise, it will be 0. We use cell D29 to contain the objective variable (i.e., the total number of distribution centers needed). In D29, we type in =SUM(C32:V32) Our goal is to minimize the value in cell D29. (3) Set up constraints In cell B35, we type in =SUMPRODUCT($C:$V,C6:V Note: =SUMPRODUCT($C:$V,C6:V6) equals to =$C*C6 + $D*D6 + $E*E6 + … + $V*V6 We use this function (i.e., =SUMPRODUCT($C:$V,C6:V6)) to see if there is at least one distribution center serving the Ashtabula county. We then drag the autofill button of B35 to the rest of counties (4) Set up Solver as shown below.
See step (5) of how to set up the constraints. ) How to set up the constraints Click Add next to the “Subject to the Constraints†box In the left hand box, select cells from B35 to B54. In the dropdown list in the middle, choose >=, and type in 1 in the right hand box, and click OK to add the first constraint. 7 Click Add next to the “Subject to the Constraints†box again. In the left hand box, select cells from C32 to V32. In the dropdown list in the middle, choose bin, and then the value in the right hand box will change to binary automatically.
Click OK to confirm. By doing so, we specify the decision variables can get either a 0 or a 1 as the value. ) After clicking the Solve button, choose “Keep Solver Solutionâ€, and click OK. From the analysis result, we find that the distribution centers should be built in Ashland county, Stark county, and Geauga county. By doing so, we need a minimum of 3 distribution centers to serve all 20 counties. As you can see in this example, the binary analysis is a very useful technique for logistic optimization, location based service, and supply chain management.

Paper for above instructions
Introduction
In the realm of Economics 1025, various fundamental concepts including market dynamics, industry structures, and interventions are utilized to analyze contemporary economic situations. This paper will delve into four different led questions from the case analyses presented for Semester 1, 2021, with a focus on drug markets and industrial organization theories. Each analysis will leverage economic theories, models, and, where applicable, empirical data to draw conclusions relevant both to the questions at hand and broader economic implications.
Question 1: Demand-supply Analysis of Penicillin
Demand-Supply Model Overview
Generic drugs, such as penicillin, have experienced altered consumer preferences during the COVID-19 pandemic due to perceived efficacy against infections related to the virus. In this context, the demand-supply model illustrates how such preference shifts impact the penicillin market and related sectors, notably the pharmaceutical and healthcare industries.
Market Dynamics
Assuming demand for penicillin spikes amid pandemic fears, we observe a rightward shift in the demand curve (D1 to D2), as shown in Figure 1. Assuming that penicillin's supply remains relatively constant short-term (S), an increase in demand leads to a new equilibrium price, resulting in higher quantities sold at elevated prices.
Impacts on Related Markets
Two secondary markets affected by this demand surge are over-the-counter antibiotics and the healthcare service market. An increase in penicillin sales may lead pharmaceutical companies to ramp up production of related antibiotics, thus enhancing overall supply in that sector (Smith et al., 2021). Additionally, with more physician consultations and increased prescriptions, the healthcare market may experience more strain, possibly leading to longer wait times and elevated healthcare costs.
Question 2: Market Failure and Government Intervention
Inefficiencies of Antibiotic Use
The misuse of antibiotics like penicillin contributes to the growing concern of antibiotic resistance. A classic example of market failure exists where uninformed consumers and doctors may contribute to excessive prescriptions, creating negative externalities (Homburg & Becker, 2020).
Government Intervention Strategies
Government interventions may include implementing stricter prescription rules, mandatory education programs regarding antibiotics, and initiatives for public awareness campaigns that advocate responsible antibiotic use.
However, potential problems associated with these interventions can arise. Stricter regulations may lead to access issues for patients who genuinely need antibiotics since doctors might become overly cautious, leading to under-prescribing (Friedman et al., 2020). Furthermore, public awareness programs can be ineffective if not tailored appropriately to engage the target demographic.
Question 3: Industry Structure of Pharmaceutical Firms
Market Concentration in Pharmaceuticals
The pharmaceutical industry, characterized by high fixed costs and significant barriers to entry, primarily operates under oligopoly or monopolistic competition frameworks. The concentration of market power among firms like Pfizer, Roche, and Merck leads to increased research and development (R&D) investments aimed at creating innovative antibiotic drugs (Leal & Camacho, 2020).
Government Concerns
Governments may legitimately be concerned about monopolistic behaviors and lack of competition which can stifle innovation and increase prices. The challenge lies in balancing sufficient profit incentives for R&D endeavors while preventing exorbitant pricing strategies that could limit access (Grabowski & Henderson, 2018). To facilitate this, governments can consider frameworks such as price regulation or incentivization of multi-firm collaborations in R&D.
Question 4: Vertical Integration Decisions for Pfizer
Optimal Boundary of the Firm
When making decisions about whether to develop new antibiotics in-house or outsource aspects of production, firms like Pfizer must assess several factors aligned with transaction cost economics.
Make-or-Buy Analysis
Pfizer should analyze the benefits of vertical integration by considering the stages of the antibiotic production chain: R&D, production, and distribution (Williamson, 2020).
1. In-house Development: Pfizer should conduct critical R&D internally due to proprietary knowledge and control over the processes involved in antibiotic discovery. Internalizing this stage would help safeguard intellectual property and innovations.
2. Outsourcing Production: If manufacturing capabilities depend heavily on specific machinery or facilities that demand significant investments, Pfizer might opt to outsource production to contractors specializing in pharmaceuticals.
This strategy would allow Pfizer the flexibility to scale production up or down based on demand while enabling better resource allocation to internal R&D efforts.
Conclusion
Addressing key questions on antibiotic use, market dynamics, and industry structures demonstrates the interconnectedness of economic theory and practical implications within the healthcare market. The trends observed, coupled with proactive government policies, could steer the pharmaceutical industry effectively towards innovation while minimizing potential issues such as market failure and inequities in access.
