а) Whаt is а market failure? Explain why healthcare and health insurance markets may be particularly susceptible tо market failure. Identify and briefly explain twо examples оf market failure that are relevant to healthcare. (10 points) b) Explain how risk and uncertainty affect an individual's decision to purchase health insurance. In your answer, discuss expected utility, risk aversion, and why individuals may differ in their willingness to purchase insurance. Apply your discussion specifically to health insurance. (13 points) c) Explain adverse selection and moral hazard in health insurance. How does each arise, and how can each contribute to inefficiency or higher healthcare spending? Identify one mechanism that insurers or policymakers may use to reduce the effects of each problem. (15 points)
As аn expert in Heаlth Outcоmes аnd Implementatiоn Science, yоu are regularly asked to help other researchers choose the best design for their study. A team of investigators approaches you about studying whether happiness influences the protection received from the influenza vaccine in the United State. The investigative team provides you with the following background information: Influenza burden in the United States varies widely each year. Between 2010 and 2020, the Centers for Disease Control and Prevention estimate that influenza caused 9 to 41 million illnesses, 140,000 to 710,000 hospitalizations, and 12,000 to 52,000 deaths each year. Between August 2005 and June 2014, an estimated 40,127 death (95% Confidence Interval: 25,694 to 59,210) were averted due to influenza vaccination. 89% of the influenza-associated deaths averted by the influenza vaccine were among people aged 65 years and older. Nationwide, 474% of adults aged 18 years and older received the influenza vaccine for the 2022 to 2023 season. Among adults aged 65 years and older, 71% received the influenza vaccine in 2022 to 2023. The amount of an individual's immune response to a vaccine influences how protective the vaccine will be when the body encounters the virus. Positive affect (happiness) is related to higher antibody production or higher immune responses compared to negative affect. Using complete sentences and paragraph format, create a one-page research proposal for the investigators. Make and explain any necessary assumptions. You are not expected to be an expert on influenza vaccine, happiness, or their relationship. Your answer will be evaluated on the reasonableness and justification of your design. Be sure to include: A suggested hypothesis including the four criteria for a good hypothesis. The best type of study design and why it is the best choice. Hint: consider the outcome of interest, the subjects, the exposure of interest, and who assigned the exposure. The main details of your study design, including: The main design elements (setting, participants, etc.) The outcome and exposure variables The data sources and how you will measure the outcome and exposure Two potential biases and how to measure or minimize them Grading Rubric Question 2 Grading Rubric Quality Points Reasoning Conceptual Understanding Exemplary 50 The student demonstrates complex critical thinking skills and applied relevant concepts. All information provided was justified clearly and reasonably. The student demonstrates understanding the covered design features. All information included was accurate. Competent 40 The student applies relevant concepts and made reasonable arguments. In general, critical thinking is demonstrated, but some components need more support. The student demonstrates understanding of study design by using correct terminology and accurate information. Adequate 35 Most information is supported with evidence from course concepts. Holes in critical thinking are apparent. The student demonstrates adequate understanding of the study design. Minor inaccuracies or use of incorrect terminology. Poor 20 Limited support of information and decisions. The student demonstrates some understanding of study design. Substantial inaccuracies are included in the description. Unsatisfactory 0 The student does not justify information or apply course concepts critically. The student does not demonstrate understanding of the ideas and issues. Little to no information from the course is used to support answers.
In GMS 6822, we explоred the cоncept оf Heаlth-Relаted Quаlity of Life (HRQOL) and discussed how definitions and priorities can vary depending on the population and context. In this question, you will apply those ideas to three example survey items, each measuring a different domain of HRQOL. Your task is to identify a relevant population, evaluate how well each item fits that population, and revise the items as needed. Example Items Physical Functioning: “On a typical day, how much difficulty do you have walking one block on level ground?” Response format: No difficulty / Some difficulty / A lot of difficulty / Unable to do this Emotional Well-being: “Over the past two weeks, how often have you felt calm and peaceful?” Response format: Never / Rarely / Sometimes / Often / Always Social Functioning: “How much has your health interfered with your ability to visit or spend time with friends and family?" Response format: Not at all / A little / Moderately / Quite a bit / Extremely For this question, answer the following three short-answer essays: Identify the population Name the population you are interested in. In 1 to 2 sentences, explain why assessing HRQOL is especially important in this group. For each of the three domains represented by the example items (Physical Functioning, Emotional Well-being, and Social Functioning), state whether each domain is relevant to your population and, in 1 to 2 sentences, explain why or why not. For each of the three example items: Indicate whether the item is appropriate as written for your population, or whether they should be revised. Indicate whether the response options are appropriate as written for your population, or whether they should be revised. if revision(s) is / are needed, rewrite the item(s) and / or their response format(s) and, in 1 sentence, justify your revisions. If no revision is needed, explain in 1 sentence, why the item works as written for your population. For Question 1 Part 3, you may use the following structure to help you: Example Item 1: _______________ Item appropriateness for population: _______________ Response options appropriateness for population: _______________ Revision / justification or explanation why no change is needed: _______________ Example Item 2: _______________ Item appropriateness for population: _______________ Response options appropriateness for population: _______________ Revision / justification or explanation why no change is needed: _______________ Example Item 3: _______________ Item appropriateness for population: _______________ Response options appropriateness for population: _______________ Revision / justification or explanation why no change is needed: _______________
