How to Pass Examinations in Economics(*0)
George J. Stigler
From "The Intellectural and the Marketplace"

Students always display a powerful, not to say unhealthy, interest in how

to answer questions on examinations in economics. Thay can do fairly well with

the essay, or subjectivem questions, but they do not seem at home with the

true-false, or objective, questions. And yet the latter questions are very

easy. I shall illustrate the proper techniques by using questions bfrom the

Students Manual to Accompany the Elements of Economics by Lorie Tarshis, able

students will discover that the appendix to the manual gives the answer to the

true-false questions (which are called comprehension tests); so it will save

time if I reproduce the answer with the question.


It is very important that the student gain self-confidence, so I shall

begin with a simple example:


9. Taxes constitute a part of fixed costs. (Answer: F)(*2)


The indicated answer is F is, of course, T. It is important to note that

this answer has a very general validity－for example:


9a. Taxes do not constitute a part fixed cost. (Answer: F)

9b. Taxes constitute a part of variable costs. (Answer: F)

9c. Taxes do not constitute a part of variable costs. (Answer: F)


Every cost, it must be remembered, is fixed or variable, and not both

simultaneously. A tax is a cost. But some taxes vary with output and some do

not, and the statement refers to taxes in the plural. This means that perhaps

both fixed and variable taxes are being referred to. Hence, the statement is

partly right, part of the time, and therefore false.



Lesson 1: A Statement That Can Be False is False
