Andrew, a college student, loves drinking coffee late at night to study for exams. Having no income, he is used to buying cheap, bad-tasting coffee, such as Beanlightened, that he needs to grind and brew himself. The coffee tastes putrid but, with enough cream and sugar, Andrew is able to tolerate it. Occasionally, he does go out to Starbucks when he has spare money. After graduation, Andrew gets a job working at a database firm as a programmer. His income is now a healthy $75,000 a year, and he decides he has had enough bad-tasting coffee. He ends up buying coffee daily from Starbucks, even though it costs significantly more than Beanlightened. a) a change in expectations. b) a change in the number of consumers. c) a change in a related good or service. d) a change in technology. e) a change in income. Beanlightened coffee is for Andrew a(n)...
e) change in income inferior good
The accompanying graph represents a hypothetical market for luxury automobiles. Suppose that a major luxury car producer exits the market in order to produce more economy cars. At the same time, a new tax law means that many tax payers will receive large refunds this year. According to a marketing firm, the result is a higher quantity of luxury cars selling at higher prices. Manipulate the graph to demonstrate what must be happening to supply and demand.
Demand shifts to the right , supply shifts to the left
Demonstrate how an increase in the price of penne, a different type of pasta, and a decrease in the price of meatballs will affect the supply and demand of spaghetti pasta. Assume that producers of spaghetti pasta do not also produce penne.
increases demand
