Econ100b Macroeconomics Mid-Term-2 Review

For True/False Questions keep in mind that being correct in the “true/false/uncertain” sense will only buy you one or two points out of the five possible. Graders are instructed that [paraphrasing] “four points may be fully correct, but not quite excellent work” in terms of one's explanation as to why the answer is true/false/uncertain. 
Thus, my advice to you: study for over the top, fully correct & comprehensive & non-rambling answers. 
I do my best to give you solid examples of those below.


If output is below potential, unemployment will be higher than its natural rate.
    See page 228+  Okun’s Law.
    Solution (Okun's Law Application)


Unemployment and short-run output are negatively related.
    See page 228+  Okun’s Law.
    Solution (Another Okun's Law Application)


If output is above potential, then inflation will fall over time.
    See page 224+  Phillips curve.
    Solution (Phillips curve)


The Phillips Curve predicts a negative relationship between output fluctuations and the change in inflation.
    See page 224+  Phillips curve.
    Solution (Phillips Curve II)



In the IS equation, if   then short-run output 
     See page 246 (of Jones Macro Econ)
    Solution (IS Curve Equation)


Suppose that initially . Then there is a demand shock to consumption where and the Then short-run output will rise by 1%
    See page 246-247 (of Jones Macro Econ)
    Solution (IS Curve Equation)


  The fiscal stimulus packages shifts the AD curve up.

    See the AS/AD chapter.

    Solution (AS/AD Example)



 If income in the UK increases, this would cause the AS curve in the US to shift to the right.

     See Chapter on AS/AD Framework. Example 3 “A Positive AD Shock”.

     Solutions (AS Query)



 If consumption increases by a constant share of short-run output, economic shocks cause larger output fluctuations.

    See the IS Curve chapter. Multiplier effects.

    Solution (Consumption Multiplier)    







Long Problems - each 'long problem' usually accounts for a quarter of the test's points. Worth about five true/false problems in total. Long problems center around one of the major topics in the class (the Solow Model worked through and applied, the Romer model worked through & applied, so on).
