Consider an infectious disease with the following characteristics:
Individuals can exist in three states, susceptible, infected, and recovered. Once recovered, an individual
cannot be re-infected and remains immune for life.
The transmission rate, t, is 1/20.
The recovery rate, k, is 1/5.
Each person interacts randomly with others in the population and has contacts with 10 people each
time period.
There is no birth or death in the population.
-Initially all people are susceptible.
- No one dies from the disease and there is no treatment.
a) Draw a compartmental model for this infectious disease.
Consider an obstetrician who can perform two types of deliveries: normal deliveries and cesarean deliveries. Each typeof delivery provides different levels of income for the physician, and the physician has some ability to induce patientsto opt for cesarean deliveries. The model is as follows:The physician’s utility is defined as:U = U(Y, I)where:• Y is the income from performing deliveries.• I is the total disutility from inducementThe income Y from deliveries depends on the type of delivery:Y = Yn · N + YC · Cwhere:• Yn is the income per normal delivery, Yn = 1, 000• YC is the income per cesarean delivery, Yc = 1, 500,• Initial number of births Binitial = 100,• Post-shock number of births Bshock = 90,• a(i) = 0.1 + 0.05i is the fraction of total births that are cesareans, which increases with inducement level i,• the physician sets the inducement level to i = 2.• N = B · (1 − a(i)) is the number of normal deliveries,• C = B · a(i) is the number of cesarean deliveriesDue to a…

Q is the number of units of output per day when the firm rents K units of capital and employs L workers each day. The manager has been given a production target: to produce 8,000 units per day. She knows that the daily rental price of capital is $400 per unit and the wage rate is $200 day. a. What is the returns to scale of this production function? Show mathematically. b. Currently the firm employs 80 workers per day. What is the firm’s daily total cost if it rents just enough capital to produce at its target? c. Compare the marginal product per dollar spent on K and on L when the firm operates at the input choice in part (b). What does this suggest about the way the firm might change its choice of K and L if it wants to reduce the total cost in meeting its target? Explain your answer very clearly. d. In the long run, how much K and L should the firm choose if it wants to minimize the cost of producing 8,000 units of output a day?…arrow_forward
- Andrew’s utility depends on consuming L, hours of leisure and Y a composite good. Andrew can work as many hours as he wants to at the wage rate of w, and the price of Y is $1. Andrew’s indifference curves exhibit diminishing MRS. When Andrew’s wage rate decreases, he spends less time working. Answer the following questions using a indifference curve-budget line diagram. Explain your answers carefully. a. Does the substitution effect cause him to work less hours? (If the direction of the effect is ambiguous, say so, and show why on your diagram) b.
