Miles is 3 years old and because his grandparents love to spoil him, they have given him money to spend at the toy store as a birthday present. Miles' number-one favorite thing to play with are building blocks. Assume that Miles' utility will increase by 100 units if he purchases a new set of building blocks and and it will cost him $50. Miles's second favorite thing to play with are firetrucks. Firetrucks cost $20 and each new firetruck improves his utility by 80 units. Miles' third favorite toy are trains. Trains improve his utility by 15 units and cost $5 each. Miles doesn't have to spend all of his money at once, but wants to get as much happiness as possible from his money. If Miles buys only one toy, which should he buy to maximize his utility? a) a fire truck b) building blocks c) a train

a) a fire truck

An increase in the price of good X while holding income and the price of good Y constant will: a)have a positive substitution effect, leading the consumer to increase consumption of good X because of the increase in the marginal utility per dollar spent on good X. b)have a negative substitution effect, leading the consumer to decrease consumption of good X because of the decrease in the marginal utility per dollar spent on good X. c) cause the consumer to substitute away from good Y toward good X. d) cause the consumer to purchase more units of good X because of the income effect.

b)have a negative substitution effect, leading the consumer to decrease consumption of good X because of the decrease in the marginal utility per dollar spent on good X.
