A. Short-Answer, Essays, and Problems
1. What is a brief definition of economics? What are the conditions that give rise to this definition?
2. What are the three interrelated features of the economic perspective?
3. What do economists mean when they say that “there is no free lunch”? Give another example to which this
statement applies.
4. (Consider This) Some stores give “free” products to consumer. An economist would say the products are
not free. Why the difference?
5. Is rational self-interest the same thing as selfishness? Explain.
6. Use marginal analysis to explain why it is possible to “have too much of a good thing.” Use education as
an example.
7. (Consider This) How can the economic perspective help us understand the behavior of fast-food
consumers? Explain several insights it provides about customer behavior.
8. The distinguished economist Kenneth Boulding stated: “Theories without facts may be barren, but facts
without theories are meaningless.” Explain what he meant.
9. What are the distinctions made in the text among the terms “hypotheses,” “theories,” “laws,” and
“principles”?
10. Why are economic theories and principles imprecise? Shouldn’t they apply to everyone?
11. Explain the importance of the ceteris paribus or “other-things-equal” assumption.
12. “Bad theories are abstract and therefore unrealistic; good theories are fully realistic and fit all the facts.”
Evaluate.
13. “Gathering economic facts is futile unless accompanied by economic analysis.” Explain.
14. “To be sure, any theoretical model must be abstracted ‘from the richness and complexity of behavior.’
However, abstraction becomes falsification when it so simplifies human behavior as to leave it
unrecognizable and unexplained.” Explain.

macroeconomics (MAC).

encountered in the study of economics. Indicate following each statement the type of pitfall involved.
(a) “July is the month with the most ice cream sales and also the month with the most drownings.
Therefore, the more ice cream people eat, the more likely they are to drown.”
(b) “Dry weather in the county where Farmer Brown lives decreased his income because his crop was so
poor. Therefore, when there is dry weather in the nation as a whole all farm incomes will suffer.”
(c) “I have to live within my income. Therefore, governments should not be allowed to borrow money.”
(d) “National health insurance plans are socialistic.”
57. (Last Word) What is the fallacy of composition? Give an economic and a non-economic example.
58. (Last Word) Explain the economic fallacy in the statement: “If the Jones family would just cut up their
credit cards and live within their means, they’d be better off. And if consumers in this nation cut up their
credit cards and lived within their means, the nation would be better off.”
