Consider a student who purchases education (x) and other goods (y). The student has preferences over these goods given by u(x,y) = ln(x) + 3ln(y). The prices of education and other goods are, respectively, px = 10 and py = 5, and the student’s income is I = 20.

1. What do limMUx(x,y) and limMUy(x,y) tell you about the optimal consumption x→0 y→0 bundle? (2 points)

2. Find an expression for the slope of the indifference curve through the point (x,y). (2 points)

3. Write the Langrangian for the student’s optimization problem and derive the first orderconditions assuming an interior solution.

Consider a student who purchases education (x) and other goods (y). The student has preferences over these goods given by u(x, y) = ln(x) + 3ln(y). The prices of education and other goods are, respectively, px = 10 and py = 5, and the student’s income is I = 20. A. Graph the budget constraint, IEP, optimal bundle (x ∗ , y∗ ), and the indifference curve passing through the optimal consumption bundle. Label all curves, axes, slopes, and intercepts....

A consumer's preferences are given by the utility function u=(107)^2+2(x-5)y and the restrictions x>5 and y>0 are imposed. 1. Write out the Lagrangian function to solve the consumer's choice problem. Use the Lagrangian to derive the first order conditions for the consumer's utility maximizing choice problem. Consider only interior solutions. Show your work. 2. Derive the Optimal consumption bundles x*(px,py,w) and y*(px,py,w) 3. Use the first order condition from 1 to calculate the consumer's marginal utility of income when w=200,...

You are a consumer who consumes goods X (education) and goods Y (recreation), where the price of good X is PX and the price of Y is Py. Your income that can be allocated to purchase these two items is M. Question a. What happens if the price of education rises? Describe the substitution effect and the income effect. b. Derive the demand curve for education.

In a two goods (x and y) world, two districts (A and B) are identical, except the prices of good x (Px) and good y (Py) are higher and lower in district A, respectively. Suppose two identical individuals (i.e. same preferences and income) live in the two districts separately and their optimal choices are interior solutions. Evaluate the following statement: ‘The MRS at the optimal choices of two individuals are the same’. True, false, or uncertain? Explain your answer intuitively...

Dan’s preferences are such that left shoes (good x) and right shoes (good y) are perfect complements. Specifically, his preferences are represented by the utility function U (x, y) = minimum{x, y}. (a) Draw several of Dan’s indifference curves. Which bundles are at the “kink- points” of these curves? (b) Assume that Dan’s budget for shoes is M = 10 and that the price of a right shoe is py = 2. Find and draw Dan’s demand curve for left...
