The Final Exam will be held in our regular classroom at the regular time

First, look at the midterm study guides. All that material is fair game for the exam

  • This is a comprehensive final exam
  • The exam will probably be about 40% new material, and 30% from each midterm
  • The grade will be about 1/3 written and 2/3 multiple choice exam

Some materials to study

  • Review Canvas Quizzes (CQ): Bold indicates you should take another look
  • Note: DO NOT submit any remaining attempts these assignments, as it will convert any grade you had previously received to a zero and thus negatively impact your grade.
    • CQ1: #1, 7, 11, 13
    • CQ2: #8, 10, 20, 24, 27, 28, 29, 30, 31, 32, 33, 34
    • CQ3: #5, 10, 11, 15, 17
    • CQ4: #8, 11, 13, 14 and closely review #4, 5, 6, 7
    • CQ5: #8, #9, #11, #16, #19, #22, #25, #26, #32
    • CQ6: #9, #11, #12, #15, #16
    • CQ7: #6, #7, #11, #15, #16
    • CQ8: #4, ,#5, #8, #9, #14, #17
    • CQ9: #9 and #13, but also look at #2, #4, #8, #10
    • CQ10: Look over #2, #6, #7, #11-15
    • CQ12: Review - #3, #4, #5, #8, #9, #12, #14, #21
  • Review FlatWorld Assignments for more help

  • Review Midterm take home questions (updated for spring 2022)
  • Midterm 1 Numbers: 1, 5, 6, 7, 10, 17, 20, 21, 24, 27, 28, 29, 30
  • Midterm 2 Numbers: 1, 2, 6, 7, 8, 9, 15, 18, 19, 20, 23, 26, 27, 28
  • All short-answer questions from both midterms are fair game
  • Go back through readings & terms for all chapters related to lectures

New Material (Units 8-12)

  • Get a good grasp on the big questions. The exam is not limited to this, but this hits on the major point value questions.
    • Understand marginal revenue product and the demand for labor and capital
      • How do changes in interest rates impact how much capital you might hire?
      • How do changes in wages impact how many workers you might hire?
    • 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
    • Savings and Investment model (discussed as part of Unit 11) helps us determine “neutral interest rates” or the “natural rate of interest”
      • This is also known as $r^*$, the interest rate where $Y=Y^*$
      • How things like optimism, 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?”)
      • Know how to sketch the Keynesian Cross diagram
      • How do you identify output gaps? Can these persist at equilibrium?
      • Know how to use $PAE = C+I^p+G+NX$ and $C=\bar{C}+mpc(Y-\bar{T})$
        • We also assume that $I^p = \bar{I}, G=\bar{G}, NX = \bar{NX}$ such that the “bar” means exogenous
        • Exogenous means determined outside of the model
      • Find the PAE equation. Typically $PAE = [\bar{C}-mpc(\bar{T})+\bar{I}+bar{G}+\bar{NX}]+mpc(Y)$
        • Use the equilibrium condition $Y=PAE$ @ $Y^e$ to solve for equilibrium
      • Understand what the fiscal/spending multiplier is, and how to find it
      • How could you use government policy (tax or spending) to eliminate any output gaps?
        • $\Delta Y = \frac{1}{1-mpc} \Delta G$
        • $\Delta Y = \frac{-mpc}{1-mpc} \Delta T$
        • How would you change interest rates to put the economy in equilibrium at potential (i.e., $Y=Y^*$)
    • 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?
      • How does the Fed’s stance on monetary policy impact the AD line in the short-run, and what do we expect in the long-run?
