Principles of Macroeconomics

Answer each of the following questions completely. Be sure to explain the rationale behind the choices you make. Questions with one-word answers such as "yes" or "no" will be awarded NO credit. The only answers that do not require an explanation are calculation problems. Calculation problems should be proven by showing the process you used or the formula you applied to solve the problem. An explanation is ALWAYS more than one sentence.

Explain Every Answer in Detail
