Final answer:
The statement that a student's utility is unchanged after the price of Starbucks coffee increased is false because utility would decrease when a preferred product costs more, leading to an opportunity cost if consumption behavior remains the same.
Step-by-step explanation:
The statement that a student's utility is unchanged after the price of Starbucks coffee increased, assuming that they derive equal satisfaction from Starbucks coffee and Dunkin Donuts coffee, would generally be considered false. In economic terms, utility refers to the satisfaction or benefit a consumer receives from consuming a product. When the price of a preferred product increases, and the consumer continues to consume the same amount of that product, the consumer faces an opportunity cost, as they could have substituted the product for a similar, less expensive alternative (in this case, Dunkin Donuts coffee).
If the student valued both Starbucks and Dunkin Donuts coffee equally and the price of Starbucks coffee increased, to maintain the same level of utility, they would have to adjust their consumption behavior, perhaps by switching to the lower-priced Dunkin Donuts coffee. Price hikes, such as the one faced by Netflix customers when they encountered a 60% increase to retain the same service, usually decrease the utility of a consumer if they continue to pay the higher price without change in consumption or perception of value.
