- (a) A consumer with I=$240 budget is shopping for apples (x) and oranges (y). Apples cost $1 each up until 60 units; thereafter each apple costs $2. Similarly, oranges cost $1 each up until 60 units, and thereafter $2 each. Draw the graph of feasible set of bundles for the consumer with relevant points and numbers (shade the feasible area), no explanation needed. (b) (HARD!) In (a), calculate the optimal bundle assuming the consumer’s utility function is u(x,y) = x^5y.arrow_forwardPROBLEM (5) Cars (x) is a normal good, and public transportation (y) is a substitute for cars. The demand for cars(x) is given by where Qp = 20 ± px ± py ± pfuture ±I where px is the price of cars, py is the price of public transportation, pfuture is the expected future price of cars and I is the average income level. (a) Decide whether a plus (+) or a minus (-) sign is appropriate for each "+" in the demand equation above. (b) Does the demand become more or less elastic (at a given px) as py increases? (c) Calculate the cross price elasticity of demand (for cars with respect to the price of public transportation py) at the point I = 10, px = 5, py=2, pfuture = 1 (d) If the point in (c) is the market equilibrium point where the supply is known to have constant price elasticity with E = 2 at any point on the curve, derive the supply function.arrow_forwardYour own a chocolate producing company which can advertise on both television (T) and internet(I). The effect of TV and online commercials on sales is again given byS(T,I) = 500 + 48T−6T2+ 112I−6I2+ 4TI. You have a budget of $25 that you can spend on T and I. The price of aTV commercial is $12per unit and the price of an online commercial is also $12 per unit. 1. Determine the optimal level of TV commercials T and online commercials I if you have to spend all of your budget. You should provide two methods to solve this, by direct substitution and by setting up the Lagrangian. Is the Lagrange multiplier positive or negative? Give an intuitive interpretation of why this is the case? 2. Now determine the optimal level of TV commercials T and online commercials I if you DO NOT have to spend all of your budget. Do you obtain the same answer as subquestion 5.1? What is the Lagrange multiplier equal to in this case? Discuss.arrow_forward
- You run a coffee shop that is open all day. You are considering staying open in the evening. The total benefit (i.e., revenue) from keeping your coffee shop open for each additional hour at night is shown in the table. Fill out the marginal benefit (the difference from one row to the next). (Enter your answers as a whole number. Include a negalive sign (-) if the answer is negalive but do not include a plus sign (+) if the answer is positive.) Hours per Night Total Benefit $0 Marginal Benefit 80 120 150 4 170 5 180 6 170arrow_forwardwhy is there no inclusion of the parameter z in the solutions and the budget constraint?arrow_forwardQuestion: Finn is in charge of decorations for an upcoming festival, and he is planning to decorate withclovers (C) and flags (F). Suppose his preferences over decorations can be represented by theutility function: U(C,F) = C3/4 F1/4 **For this problem, assume C and F are infinitely divisible so you don’t need to worry about restricting to whole-number answers. a.) Write Finn’s budget constraint as a function of the prices PC , PF and his budget I. b.) Write Finn’s constrained optimization problem in Lagrangian form and derive the threefirst order conditions.arrow_forward
- Refer to the budget line shown in the diagram above. At point U, __________. Question 3 options: P1/P2 = MU1/MU2 pizza is an inferior product P2/P1 = MU2/MU1 roses are an inferior productarrow_forwardSuppose your income is 200, the price of good x is 2, and the price of good y is 3. You know that your utility function is U= 2(xy)^3. (A) What amounts of x and y do you choose? (B) Can you generalize your choices to demand curves for x and y for any prices and income?arrow_forwardThere are two shows on Netflix that Jeff can watch, Show 1 and Show 2. x₁ measures the number of episodes watched of Show 1 and x₂ measures the number of episodes watched of Show 2. Jeff's preferences can be represented by u(x₁, x₂) = x² + ax². Jeff has 11 hours available for watching Netflix today. Each episode of Show 1 lasts 30 minutes, while each episode of Show 2 lasts one hour. For all question parts, round to three decimal places if necessary. For parts (a) - (f), let a = 1. Draw Jeff's indifference curves for the utility levels u = 4, 9, 16. Draw a straight line between the bundles (x₁, x₂) = (4, 0) and (x₁, x2) = (0, 4). Now, use your picture to determine whether the following two statements are true or false. Answer "1" for true. Answer "0" for false. a) Statement 1: Jeff's preferences are strongly monotone. 1 b) Statement 2: Jeff's preferences are strictly convex. 0 c) Find the bundle at which one of Jeff's indifference curves is tangent to the budget line.
