Answer all of the following questions from the book and those below. HW #2 is due in class on Wednesday Feb 22nd .
A. Questions from Text and Readings
R&T Chapter 2-5 (online), Chapter 2.4 Review and Practice (in printed textbook); Concept Problems 2, 3;
(for Extra Practice complete Numerical Problems 1 – 5 (not required for HW1)) CP2. Why does the downward-sloping production possibilities curve imply that factors of production are scarce?

CP2. A downward-sloping production possibilities curve shows that in order to obtain more of one good (or service), another must be forgone. That is the meaning of scarcity—the situation where we are forced to choose among alternatives.

CP3 In what ways are the bowed-out shape of the production possibilities curve and the law of increasing opportunity cost related?
