1)Find
Marginal Utility for x and determine if it is diminishing
Marginal utility for y and determine if its diminishing
Marginal rate of Substitution of x for y (MRSxy) and determine if its diminishing
U (x, y) = 2x2/3y1/3
U (x, y) = x3 + 4y1/4
2. Continental Long Distance Telephone service offer am optional package for in-stare calling whereby each month the subscriber gets the first 50 minutes of in-state calls free, the next 100 min at $0.25/min, and each additional time at the normal rate of $0.50/min. Draw the budget constraint for in-state phone calls and the composite good for a subscriber with an income of $400/month.
Composite goods imply all other goods: Assume it costs $1 and its on the horizontal axis.
