If an economy is operating on its production possibilities frontier, it must be using its resources efficiently.

If an economy is operating on its production possibilities frontier, it must produce less of one good if it produces more of another.

Points outside the production possibilities frontier are attainable but inefficient.

If an economy were experiencing substantial unemployment, the economy is producing inside the production possibilities frontier.

The production possibilities frontier is bowed outward because the trade-offs between the production of any two goods are constant.

10.

An advance in production technology would cause the production possibilities curve to shift outward.

11.

Macroeconomics is concerned with the study of how households and firms make decisions and how they interact in specific markets.

The statement, "An increase in inflation tends to cause unemployment to fall in the short run," is normative.

13.
