The constraint is given as .
(a) For the given values of P and W, we have or as the constraint. The utility function is . The lagrangian to maximize the utility with the given constraint will be . The FOCs are below.
or or or .
or or or or .
or or or .
Comparing the first two FOCs, we have or or , which is the optimal combination of consumption and leisure. Putting that in the third FOC, we have or , and as , thus or .
Hence, the optimal level of consumption is 120 units, while the optimal amount of leisure is 12 hours. She is working hours a day.
(b) The utility function would be . The budget constraint would be or , as P is 1. The lagrangian would be . The FOCs would be as below.
or or or .
or or or or .
or or or .
Comparing the first two FOCs, we have or or , which is the optimal combination of C and L. Putting it in the third FOC, we have or or or , and since , we have or .
The parameter alpha is the preference of consumption against leasure. As alpha tends to 1, the preference to consumption is more and preference to leasure is less, and vice cersa as alpha tends to 0. This can also be seen in the equilibrium bundles of C and L.
(c) We have and . The effect of alpha on C would be or . The effect of alpha on L would be or .
As can be seen, as alpha increases marginally, optimal C would increase by 24W, while optimal L would decrease by -24. It is as alpha denotes the preference towards consumption.
(d) The graph would be as below.
As W increase, Anne's budget lines moves to right in an angular movement. Also, except zero consumption and L=24 point, all the points in the new budget line are more preferred than before, as they have more C for the same L than before.

This problem focuses on the labor supply effects of subsidies. Assume Ann gets utility from consumption c and leisure l. Ann chooses how many hours to supply to the labor market each day (h) but only has 16 hours per day for work and leisure (assuming 8 hours of sleep). For each hour she works, she earns an hourly wage w = 15. Assume Ann has no unearned income v = 0. 1. Write down Ann’s daily budget constraint in...
Use supply and demand graphs to answer the following two questions. Your submitted response to this Discussion Topic does not need to include the graphs, but your response should describe the outcome as indicated by the questions below. However, you should practice drawing the graphs both to help you get the answers, and because in the final exam you will need to be able to graph shifts in supply and/or demand, and explain the outcomes. Question 1. Draw a supply-and-demand graph...
Suppose an individual’s utility function for two goods X and Y is givenby U(X,Y) = X^(3/4)Y^(1/4) Denote the price of good X by Px, price of good Y by Py and the income of the consumer by I. a) (2 points) Write down the budget constraint for the individual. b) (4 points) Derive the marginal utilities of X and Y. c) (3 points) Derive the expression for the marginal rate of substitution of X for Y. Write down the tangency...
Instructions: Answer the following questions as completely as possible. Write your answer neatly and legibly. When drawing a graph, make sure that you label axes and curves, and include appropriate coordinates. Always show your work. Suppose that Bridget and Erin spend their incomes on two goods, food (F) and clothing (C). Bridget’s preferences are represented by the utility function U(F,C) = 10FC, while Erin’s preferences are represented by the utility function U ( F , C ) = 0.20 F^2...

Using the book, write another paragraph or two: write 170 words: Q: Compare the assumptions of physician-centered and collaborative communication. How is the caregiver’s role different in each model? How is the patient’s role different? Answer: Physical-centered communication involves the specialists taking control of the conversation. They decide on the topics of discussion and when to end the process. The patient responds to the issues raised by the caregiver and acts accordingly. On the other hand, Collaborative communication involves a...

Please read the article and answer about questions. You and the Law Business and law are inseparable. For B-Money, the two predictably merged when he was negotiat- ing a deal for his tracks. At other times, the merger is unpredictable, like when your business faces an unexpected auto accident, product recall, or government regulation change. In either type of situation, when business owners know the law, they can better protect themselves and sometimes even avoid the problems completely. This chapter...
