The best way to study is to do the assignments:

But let me page through the book and see if I can give you some hints. NOTE that these hints will not cover everything that is on the exam.

CHAPTER 5

  • have a general idea of the main sources of of revenue and the main expenditures categories for each level of government.
  • be able to calculate marginal tax rate and average tax rate.
  • be able to calculate the amount of tax that you have to pay if you are given the marginal tax rates (See Key Question #15 p. 90).

    (Key Question # 15) Suppose in Fiscalville there is no tax on the first $10,000 of income, but a 20 percent tax on earnings between $10,000-20,000 and a 30 percent tax on income between $20,000 and $30,000. Any income above $30,000 is taxed at 40 percent. If your income is $50,000, how much in taxes will you pay? Determine your marginal and average tax rates. Is it a progressive tax? Explain.

    Total tax = $13,000; marginal tax rate = 40% average tax rate = 26%. This is a progressive tax; the average tax rate rises as income goes up.

CHAPTER 7

  • - definition of GDP
  • - what is included and what is not included
  • - what is "double counting" or "multiple counting"?
  • - calculate GDP using the expenditures approach (question #8 a, p. 129)

    a. Using the above data, determine GDP by both the expenditure and the income approaches. Then determine NDP.

    (a) GDP = $388, NDP = $361

  • - calculate and define NDP
  • - calculate and define "In" (net investment)
  • - calculate Xn (net exports)
  • - use the Income Approach to calculate NI (national income)
  • - define NI (national income), PI (personal income), and DI (disposable income)
  • - define and calculate real GDP (be able to fill in the blanks of Table 7.5 on p. 123)
  • - know what a price index is
  • - what is the CPI
  • - know whether the "shortcomings of GDP" UNDERESTIMATE or OVERESTIMATE real domestic output

CHAPTER 8

  • - know the phases of the business cycle
  • - know causes of the business cycle
  • - what is unemployment? who is included and who is not?
  • - what is full employment? Why is 4% unemployment considered to be full employment?
  • - know the types of UE
  • - GDP gap
  • - define inflation
  • - be able to calculate the inflation rate (see Key question #11, p. 151)

    This year's rate of inflation is 10% or [(121 - 110)/110] x 100.

    Dividing 70 by the annual percentage rate of increase of any variable (for instance, the rate of inflation or population growth) will give the approximate number of years for doubling of the variable.

    a. 35 years - 70/2
    b. 14 years - 70/5
    c. 7 years - 70?10

  • - demand-pull IN and cost-push inflation

CHAPTER 11

  • - this is the most important chapter so know it well
  • - the extra credit essay question will ask you to analyze a news article using the AS/AD model. Be sure to discuss which DETERMINATE changed, and USE GRAPHS to explain what happened to UE, IN, and EG. Several of these are done in our online lecture.
  • - DO THE STUDY GUIDE AND THE ONLINE REVIEW QUESTIONS 

CHAPTER 17

  • - includes some pages from chapter 8
  • - know the difference between the two types of EG discussed in class
    • (1) increasing the potential GDP and
    • (2) achieving the potential GDP.

     

    • Illustrate both using the PPC and the AS/AD graphs.

     

  • Know which "ingredients of Growth" (supply factors, demand factors, efficiency factors) causes which type of growth.
  • - Accounting for growth (pp. 312-316). Understand table 17.1 on page 313
  • - what is the "New Economy"/
  • - Is growth Desirable?

CHAPTER 22 W

  • - know the characteristics of the less developed economies ("Measures of Development" in our class lectures)
  • - know the growing income gap between the rich and the poor countries (p. 22W-3)
  • - understand how rapid population growth affects economic development in the less developed countries
  • - the vicious circle
  • - role of government
  • - role of advanced nations - understand the "Trade vs. Aid" issue. Especially see "Expanding trade" on p. 22W-12
  • - see the connection between "DVC policies promoting growth" (pp. 22W15-17) and the Structural Adjustment Policies that we discussed early in the semester
