 Get a good grasp on the big questions. The exam is not limited to this, but these are the major point value questions.
 Understand marginal revenue product and the demand for labor and capital
 Calculating unemployment rates
 Structural, cyclical, frictional, natural
 U3 v. U6
 Labor force participation rates
 Understanding Okun’s Law, and what is meant by output gaps and cyclical unemployment
 Production functions and diminishing marginal product of capital & labor
 Also know how to calculate and interpret productivity functions
 Importance of technology v. additions of capital or labor
 Spending Allocation model
 Difference of shares in nongovernment (sensitive to interest rates) v. government share (not sensitive to interest rates)
 How this model helps us determine “neutral interest rates”
 How things like optimisim, increased/decreased government spending, or increased/decreased taxes will impact interest rates
 How interest rates affect exchange rates
 Aggregate Expenditure model
 Understand mpc and the consumption function (“what is disposable income?”)
 Understand what the fiscal/spending multiplier is, and how to find it
 Know how to sketch the Keynesian Cross diagram
 How do you identify output gaps? Can these persist at equilibrium?
 How could you use government policy (tax or spending) to eliminate any output gaps?
 The Economic Fluctuations model
 How to sketch out the AD line. What are the axes? Why does the line slope downward?
 What is the IA line? Why will it tend to return to the value it should be at in the longrun?
 What is the Fed’s role in pushing the economy back to this longrun inflation rate?
 How does a change in government spending or taxation impact the AD line in the shortrun, and what do we expect in the longrun?
Equations
$ \%\Delta=\frac{newold}{old}\times 100 $
$ PV=\frac{FV}{(1+i)^n}$ with $ i $ in decimal form
$ \text{approx time to double}=\frac{70}{g} $
$ r=i\pi $ where $\pi$ is the rate of inflation
$ Y=C+I+G+NX $
$ S_{public}=TGTR $, $S_{private}=Y+TRTC$, $S_{national}= S_{public}+S_{private}$
$ S_{total}=S_{public}+S_{private}+S_{foreign} $
$ S_{foreign}=NX $
$ 1= C/Y + I/Y + G/Y + NX/Y $
$ \frac{NG}{Y^{*}}=1\frac{G}{Y^{*}} $
$ \frac{YY^{*}}{Y^{*}}=2(uu^{*}) $ with $ u \text{ and } u^{*} $ in decimal form OR
$ 100 \times \frac{YY^{*}}{Y^{*}}=2(uu^{*}) $ with $ u \text{ and } u^{*} $ in percentage form
$ PAE=C+I^p+\bar{G}+\bar{NX}$
$ Y=PAE \text{ @ } Y^e$
$ \frac{1}{1mpc} $
$ Y=AK^{0.5}L^{0.5} $
$ \frac{Y}{L}=A \left(\frac{K}{L}\right)^{0.5} $
$ \text{U3 Unemployment}=100 \times\frac{\text{unemployed}}{\text{unemployed+employed}} $
$ \text{Labor Force Participation}=100 \times\frac{\text{unemployed+employed}}{\text{population}} $
$ \text{GDP Deflator}=\frac{\text{Nominal GDP}}{\text{Real GDP}} \times 100 $

 What is the difference between real, nominal, potential, and actual GDP?
 What growth rates are we usually interested in and how are they measured?
 What are the different types of unemployment (i.e., U3, U6, frictional, structural, cyclical, natural, and actual) and how that might relate to measures like the labor force participation rate and the employment to population ratio?
 How are unemployment, inflation, and GDP are related and what role does the government, Fed or FOMC play in managing these relationships?
 What is the difference between a debt and a deficit? What is a stock variable and what is a flow variable?
