  • Review FW9, FW10, FW11, and FW 12 for more help

  • 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
      • U-3 v. U-6
    • 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 non-government (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 long-run?
      • What is the Fed’s role in pushing the economy back to this long-run inflation rate?
      • How does a change in government spending or taxation impact the AD line in the short-run, and what do we expect in the long-run?

Equations

$ \%\Delta=\frac{new-old}{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}=T-G-TR $, $S_{private}=Y+TR-T-C$, $S_{national}= S_{public}+S_{private}$

$ 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{Y-Y^{*}}{Y^{*}}=-2(u-u^{*}) $ with $ u \text{ and } u^{*} $ in decimal form OR

$ 100 \times \frac{Y-Y^{*}}{Y^{*}}=-2(u-u^{*}) $ with $ u \text{ and } u^{*} $ in percentage form

$ PAE=C+I^p+\bar{G}+\bar{NX}$

$ Y=PAE \text{ @ } Y^e$

$ \frac{1}{1-mpc} $

$ Y=AK^{0.5}L^{0.5} $

$ \frac{Y}{L}=A \left(\frac{K}{L}\right)^{0.5} $

$ \text{U-3 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 $
