- Ana decides every day how many hours to work and how much beef to consume. She spends all income earned from work each day on consumption of beef. Her utility function for free time (t, 24 hours minus hours worked) and consumption (y) is: U(t,y)=2t^1/2 + y The price per unit of beef consumed is 4 and her hourly wage is 1. Using a diagram and appropriate algebra, explain what Ana’s optimal number of hours work and units of beef consumed are each day. Ana reads a book about the impact of beef consumption on climate change and realises that there is a cost to society of her beef consumption. She takes account of this impact on society in her own decisions, incorporating a disutility of -0.03y per unit of beef consumed. She still only consumes beef and spends all income earned each day on this consumption. Explain, using a diagram and appropriate algebra, how recognition of the impact of her consumption choice on climate change impacts on Ana’s daily free time and beef…Robinson Crusoe has exactly 12 hours per day to spend gathering coconuts ( C) or catching fish (F). Let tp denote the time (in hours) spent catching fish and tc the time (in hours) spent gathering coconuts per day. Robinson can catch 3 fish per hour or he can gather 6 coconuts per hour; his "production technology" can thus be described by: F = 3tp and C = 6tc. Robinson's utility function is U(F,C) = FC where F is his consumption of fish and C is his consumption of coconuts. 1. (a) Write down Robinson's time constraint and hence find an equation for his Production Possibility Frontier (PPF). (b) Find the number of fish Robinson will catch per day and the number of coconuts he will gather per day.A student has a part-time job in a restaurant. For this she is paid $8 per hour. Her utility function for earning $I and spending S hours studying is U(I,S) = I^1/4 S^3/4 (The utility function is a measure of the `usefulness' or `worth' to the student of a certain combination of money and study time). The total amount of time she spends each week working in the restaurant and studying is 100 hours. How should she divide up her time in order to maximise her utility?
- A college football coach says that given any two linemen A and B, he always prefers the one who is bigger and faster. Is this preference relation transitive? Is it complete? The production function for puffed rice is given by q , where q is the number of boxes produced per hour, K is the number of puffing guns used each hour, and L is the number of workers hired each hour. Calculate the q = 1,000 isoquant for this production function and show it on a graph. If K = 10, how many workers are required to produce q = 1,000? What is the average productivity of puffed-rice workers? Suppose technical progress shifts the production function to , answer parts a and b for this new situation.Define Optimization in an indifference curve along with relevant examples?Given U(c, t)=3c+4t expalin what the utility function says about the marginal rate of substitution.
- Jack derives utility from Hokey course (H) and Chess course (C) as given by the following utility function:U (H, C) = √HCThe average price for the hokey course is 20 dollars and for chess course16 dollars. Moreover, Jack has a budgetof 80 dollars.a) Use Lagrange optimization method to find Jack’s utility maximization choice of consumptionbundle. Find also his utility level from consuming that bundle.b) Assume that price of chess course increases to 25 dollars. Suppose Jack also changed his budget forconsumption and we do not know it. Denote Jack’s budget by α and find his demand for H and Cunder the new conditions as a function of α.c) Find the income level which is necessary to make Jack reach the same utility level as before theprice change.Suppose Vivi’s utility function over tea and crumpets are given by U(T, C) = min(T, 3C). (a) Graphically derive Vivi’s demand for tea when her income is $60 and the price of crumpets is $2. Do this by showing her optimal consumption (exact numbers) at three different values for the price of tea. (b) What is the formula for Vivi’s demand function for crumpets when her income is $60, the price of crumpets is pC, and the price of tea is pT ? Note:- Do not provide handwritten solution.

- Elsa lives alone on an island with two goods, bananas and fresh water. Her utility function is U = BW where B is the amount of bananas she consumes and W the amount of water. Her production function for bananas is B = 6LB where LB is the amount of labour time she devotes to bananas. Her production function for water is W = 2LW where LW is the amount of labour time she devotes to water. If the total time she has available is 10, what should she do to maximize her utility?Suppose Ed's utility from the consumption of martinis (m) is proportional to the number he drinks: U(m) = m. Further, Ed is particular about his martinis: He enjoys them in exactly three parts of gin (g) to one part vermouth (v). So we can write the utility as: U(m) = U (g, v) = min (g, 3v). (a) Provide a sketch of Ed's indifference curve in the (g, v)-space for various level of utility. (a) Let the prices be p, and p, and Ed's income be I. Find the demand functions for 9 and v [Hint: Use the proportional rule and budget constraint. No need for differential calculus] (b) Using the results in (b), what is Ed's indirect utility function? (c) Find the expenditure function; given a level of utility U, and prices pg and Pv.Nora's utility function is given by U = In(C) + In(L), where U is utility, C is consumption, and L is leisure. The total time Nora has is T = 1 and is a utility maximizer. Before the Covic pandemic, the wage rate is 10, and Nora has no non-labor income. When the pandemic hit and part of the economy was locked down, Nora's wage rate decreased to 8. However, the government provided income support by sending out a non-labor income of 5 to everyone, including Nora. Nora still has a total amount of time T = 1 for leisure and work during the pandemic. Which of the following statements is correct? O Before the pandemic, Nora's labor supply is 0.2. O Before the pandemic, Nora spent time equal to 0.2 O Before the pandemic, Nora's consumption was 9. O During the pandemic, Nora's labor supply is 0.5. leisure. O During the pandemic, Nora was better off for having a higher utility level. O During the pandemic, Nora's labor supply is unchanged becauses income effects were perfectly offset by the…
