  • You are not allowed outside paper

Some materials to study

  • Go back through readings & terms for all chapters related to lectures 4, 5, 6, 7 and 8, as well as what was covered in lecture 9
  • Review CQ4, CQ5, CQ6, CQ7, and CQ8 paying close attention to the problems you did poorly on as a group. These numbers are listed below:
    • CQ4: #9, #13, & #14, and while you did OK on these other questions, please review (#1, #4, #5, #6, #7, #8, #11)
    • CQ5: #5, #8, #9, #11, #15, #16, #19, #22, #25, #26, #28, #29, #30, #31, #32
    • CQ6: #6, #8, #9, #11, #12, #15, #16
    • CQ7: #6, #7, #11, #12, #15, #16
    • CQ8: #4, #9, #14, #17
  • Review FW4, FW5, FW6, FW7, FW8 and FW9 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.
    • Firm structure & information issues (principal-agent, asymmetric information)
    • Taxation - progressive, regressive, proportional (flat) and how they relate to effective average tax rate
      • Effective average tax rate = $\frac{\text{total tax}}{\text{total income}}\times 100$
    • Moral hazard & adverse selection
    • Gini coefficients & Lorenz curves - can you draw and solve???
    • Stock pricing and returns,
      • $\frac{Div_1}{i-g}$ or
      • $P=\frac{\text{Future Price}+\text{Dividends}}{(1+i)}$
    • $\text{Div Yield}=100\times \frac{\text{Div}}{\text{Price}}$
    • Bond pricing and returns
      • $\frac{C_1}{(1+i)^1}+\frac{C_2}{(1+i)^2}+\ldots+\frac{C_n}{(1+i)^n}+\frac{F}{(1+i)^n}$
    • Relationship between interest rates and bond/stock prices
    • GDP calculation (nominal and real)
    • Growth rates of real GDP (finding annual averages)
    • Calculating inflation with GDP deflators and CPIs, $\text{GDP Deflator}=\frac{NGDP}{RGDP}\times 100$
    • Calculating CPIs
    • Adjusting prices/wages to compare “real” values at various points in time (forwards and back) \(\text{Nominal wage}_\text{YR1} \times \frac{CPI_\text{YR2}}{CPI_\text{YR1}}=\text{Real wage}_\text{YR2}\)
    • Anticipated v. Unanticipated inflation
    • Calculate growth of real prices/wages
    • Supply and demand, manipulating curves and comparative statics
    • Surplus v. shortage
    • Basic understanding of price floors and ceilings
    • Understanding of market failure and externalities
    • Total savings, $(S_\text{total}=Y-C-G-NX)$
      • OR $(S_\text{total}=S_\text{public}+S_\text{private}+S_\text{foreign}=I)$
    • Components of savings
      • National savings, $(S_\text{national}=Y-C-G)$
      • Foreign savings, $(S_\text{foreign}=-NX)$
      • Public savings, $(S_\text{public}=T-G-TR)$
      • Private savings, $(S_\text{private}=Y+TR-T-C)$
    • The components of GDP, $Y=C+I+G+NX$
    • Economic v. financial investment
    • Trade deficit v. Trade surplus v. Balanced Trade
    • Fisher equation, $r=i-\pi$
    • Market failure - rival/non-rival, excludable/non-excludable
    • Public goods, externalities, and missing markets
    • Foreign trade, tariffs and quotas
    • Exchange rates, appreciation, depreciation, strengthen, weaken, and interpret
