Suppose a hospital is planning about how many patients to treat over the next two years. One key factor the hospital needs to consider in its planning is that hospitals that see many patients in one year have lower costs of care in subsequent years. Let p be the price of hospital care, let 91 be the number of patients the hospital treats in year one, let q2 be the number of patients the hospital treats in year two, and let c₁ and c₂ be the hospital's per-patient cost in years one and two. The hospital's profits over the two year period are: II = (pic₁)91 + (p2 - c2)92 The hospital takes p1 and p2 as fixed and they choose q1 and q2 to maximize profits, II. (1) 1. Suppose, as a warm up exercise, that there is no learning by doing, and that the unit cost functions are as follows: c₁ = 21 and c2 = 92. Is the cost of caring for patients increasing or decreasing in the number of patients seen? Derive the supply function in periods one and two for the hospital. [Hint: Substitute the unit cost…
3)Suppose we are testing a null hypothesis against a two-sided alternative, then the alternative can be written as: A. E(Y) > μY,0 B. E(Y) = μY,0 C. ≠ μY,0 D. E(Y) ≠ μY,0
Econometrics Thomas Eisensee and David Stromberg wanted to measure how much news coverage of a foreign disaster impacted the amount of disaster relief provided by the U.S. government. They argue that the simple relationship would be biased. Let X = Minutes of News Coverage and Y= Disaster Aid. Choose a variable X2 that could bias the simple relationship. This variable should impact the amount of coverage and impact the amount of aid for reasons other than purely news coverage. Eisensee and Stromberg introduce an instrument Z = During the Olympics. Explain how Z could satisfy the relevant and exogenous criteria. Explain how you could use Z to estimate the impact of X on Y free from X2 bias. Hint: you should mention two stages.
In the p-value approach to hypothesis testing, we reject the null hypothesis if O p-value > 0.05 O p-value 0.05 O p-value 0.05 O p-value < 0.05

The solution is x= and y = (Simplify your answer.) O B. There are infinitely many solutions of the form x = and y =r. (Simplify your answer. Type an expression using r as the variable.) O C. There is no solution.
Suppose a US medical board is using marginal analysis to determine the optimal screening frequency for a specific disease. Below is the approximate number of early cases that screening at various frequencies will detect. The frequency of screening is how often the entire population (of 5,000 people) will be screened over a 10-year period. For example, a Frequency of 5 means the entire population will be will be screened 5 times over a 10-year period. Suppose further that each early detection case is considered to have a benefit of $50,000 and the cost of screening the population is $9,000,000. Frequency of screening the population (number of times over 10 year period) 10 1 12 3 14 Total Number of Early Detection Cases 10 400 700 900 1000 1000 I 5 Using the marginal benefit/marginal cost rule, what is the optimal frequency for screening (over this ten-year period)? 2 times 5 times 3 times 4 times
