- The Grossman model emphasizes the important roles that education, health knowledge, and expectations about future income and health play in the choices that determine health in both the short and long runs. Education both increases the likelihood of having higher income, which is good for health, and can compensate for lower income in which of the following ways: a. Education is associated with better health literacy, knowledge and execution of healthy diets and lifestyles b. Education enables people to communicate better with well-educated doctors and so they learn better how to manage their own health over time c. Education enables people to read about side effects and avoid unnecessarily risky procedures d. All of the above e. None of the abovedescribe how COVID-19 may differentially affect families across the socioeconomic spectrum. That is, how might the consequences of COVID-19 for families with low SES be similar to or different from the consequences of COVID-19 for families with high SES?One of the key provisions of the Affordable Care Act was the ensuring coverage for “pre- existing conditions,” which had formerly been excluded from insurance plans as people with known medical conditions that will require treatment with certainty, the costs of which are virtually guaranteed to be more than the premiums that insurance companies could charge Suppose we have a population of patients with different health profiles, so that the cost of future treatment X is uniformly distributed on the interval [0, 1000], X˜ ∼ U [0, 1000]. Suppose that we have an insurance company that is bound to offer the same plan to all customers who wish to buy it and cannot deny coverage based on pre-existing conditions. The market for insurance is competitive, so that the insurance company must set its premium equal to the expected future payout. P = E[X˜] Another key provision of the ACA was the “individual mandate,” which required…

Check all that apply Group of answer choices Vaccination rates are significantly lower in developing countries, suggesting that the situation will likely worsen for developing countries relative to developed countries over time Because developing countries have younger populations, the mortality rates from COVID are higher than they are for developed countries with larger old-age populations Even though more people live in developed countries, there are higher country-by-country mortality rates in developing countries More people live in developing countries, meaning that even though mortality rates by country may be lower, developing countries are still contributing a majority of global deaths due to the disease Reported deaths from COVID in the poorest countries are very low despite evidence of significant increases in mortality since the pandemic…
