- John wants to buy a used car. He knows that there are two types of car in the market, plums and lemons. Lemons are worse quality cars and are more likely to break down than plums. John is willing to pay £10, 000 for a plum and £2, 000 for a lemon. Unfortunately, however, he cannot distinguish between the two types. Sellers can offer a warranty that would cover the full cost of any repair needed by the car for y ∗ years. Considering the type and likelihood of problems their cars can have, owners of plums estimate that y years of guarantee would cost them 1000y, owners of lemons estimate that the cost would be 2000y. John knows these estimates and decides to offer £10, 000 if a car comes with y ∗ years of warranty, £2, 000 if a car comes without warranty. For which values of y ∗ is there a separating equilibrium where only owners of plums are willing to offer the y ∗ -years warranty? Clearly explain your reasoning.A person lives for 3 years with a disease and the current standard of care for that disease means he/she lives with a utility level of 0.7 . If that person takes a new medicine (Medicine A) because of which his/her utility level increases to 0.8, If another new medicine (Medicine B) prolongs the patient’s life by 2 years, at a utility level of 0.7,-Calculate the new QALYAn individual has the utility function U(I) = I^(1/2), where I is their net income. (Note that I to the exponent/power of 1/2 is the same as the square root of I.) The individual starts with $1600 in income. The individual has a 20% probability of being very sick, 30% probability of being slightly sick, and 50% probability of being healthy. If the individual is sick, they lose net income because they need to pay healthcare costs. The healthcare costs are $1600 if they are very sick, $700 if they are slightly sick, and $0 if they are healthy. Please use this information for the following parts of this question unless otherwise specified. What is the individual's expected utility? Suppose a health insurance company offers the individual a full insurance contract. What is the actuarially fair, full insurance premium for this individual? What is the individual's expected utility if they purchase a full insurance contract at the actuarially fair, full insurance premium?
- A health economist is conducting the analysis and making a choice between the following two choices: Choice A: there is a certain outcome that the patient will stay in chronic health state X for the rest of his life T Choice B: the treatment has two possible outcomes, either the patient is returned to full Health (1) of the rest of his life T with probability p; the patient dies (0) immediately with the remainig probability What is the utilty value of the health state X? X=P X=PT X=(1-P)/P X=PT/(1-P)Explain the effect of Covic-19 pandemic in PH in their economics.

- A researcher studying the effects of a new fertilizer on crop yields plansto carry out an experiment in which different amounts of the fertilizerare applied to 100 different 1-acre parcels of land. There will be fourtreatment levels. Treatment level 1 is no fertilizer, treatment level 2 is50% of the manufacturer’s recommended amount of fertilizer, treatmentlevel 3 is 100%, and treatment level 4 is 150%. The researcher plans toapply treatment level 1 to the first 25 parcels of land, treatment level 2to the second 25 parcels, and so forth. Can you suggest a better way toassign treatment levels? Why is your proposal better than the researcher’smethod?JUST ANSWER SUBPART 2 There are two individuals, Individual A and Individual B. Individual A has an income (Y) of 500 million Rupiah per year. If Individual A is sick, he will lose 25% of his income. Meanwhile, Individual B has an income (Y) of 100 million Rupiah per year, and if Individual B is sick, he will lose 75% of his income. The probability of Individual A and Individual B being sick is the same, which is 10%. If the satisfaction level of Individual A and Individual B is determined by their income level, based on the following function U(Y)=ln Y, would Individual A and Individual B prefer not to have health insurance? Explain Faced with fair actuarially insurance, how much premium is offered to Individual A? Is the premium rate offered the same for Individual B? Explain with the support of graphic illustrations. The government decides to provide compulsory health insurance with a premium rate for Individual A and Individual B, which is 2% of the income of each individual. In…If a person has a medical condition that has a quality of life index of 0.75, and the condition persisted for two years, then the individual would experience: a. 0.25 QALYs b. 1.50 c 0.50 d 0.75
- If a person lives for 3 years with a disease and the current standard of care for that disease means he/she lives with a utility level of 0.7.-What is the QALY? Answer in not less than 300 wordsABC Explosives has purchased fire insurance for its factory. It can institute a fire prevention program, which would cost $90, but which would lower the probability of a fire from 0.01 to 0.001. The insurance company cannot determine whether ABC has instituted the program. However, it charges a deductible in the event of a fire (i.e. ABC has to pay a certain amount to the insurance company if a fire occurs). What is the smallest deductible that will encourage ABC to institute the fire prevention program?The owner of a ski resort is considering installing a new ski lift that will cost $900,000. Expenses for operating andmaintaining the lift are estimated to be $1,500 per day when operating. The U.S. Weather Service estimates thatthere is a 60% probability of 80 days of skiing weather per year, a 30% probability of 100 days per year, and a 10% probability of 120 days per year. The operators of the resort estimate that during the first 80 days of adequate snow in a season, an average of 500 people will use the lift each day, at a fee of $10 each. If 20 additional days are available, the lift will be used by only 400 people per day during the extra period; and if 20 more days of skiing are available, only 300 people per day will use the lift during those days. The owners wish to recover any invested capital within five years and want at least a 25% per year rate of return before taxes. Based on a before-tax analysis, should the lift be installed?
