Your answers must be on the paper provided. No more than one answer per page. Do not answer two questions on the same sheet of paper. 3. If you use more than one sheet of paper for a question, write “Page 1 of 2” and “Page 2 of 2.” 4. Write ONLY on one side of each sheet. Use only pen. Answers in pencil will be disqualified. 5.

(Econ 202) Discuss gross domestic product (GDP). What does it measure? Distinguish (a) between nominal GDP and real GDP, (b) between GDP and gross national product (GNP), and (c) between GNP, net national product, and disposable personal income. What are the four expenditure components of GDP, which is the largest, and which is the most volatile? Then elaborate on some of GDP’s limitations and shortcomings. What kinds of production does GDP not capture, and why is it not necessarily a good proxy for economic well being? Give at least one example of where GDP per capita goes down but people on average are better off. 2B. (Econ 235) Draw a Bailey (or monetary Laffer) curve, clearly labeling both axes and the maximum rate of real seigniorage that a government can generate in the long-run. What are the diagram’s simplifying assumptions? Now explain in words why the point you indicated is indeed the maximum. Then illustrate on the graph how hyperinflation might get started, again explaining in words the process you are depicting.

(Econ 203) Consider the following sample semi-log regression model: -----------------------------------------------------------------------------ln(hourly wage) Coef. -------------+---------------------------------------------------------------yrs. of education 0.11 yrs of experience 0.01 married = 1 0.14 female = 1 -.26 metropolitan area = 1 0.18 Black = 1 -.08 Asian = 1 -.07 lives west region = 1 0.01 lives south region = 1 -.04 constant 1.46 -----------------------------------------------------------------------------a. What are the necessary assumptions to estimate the model using ordinary least squares? b. Provide an interpretation of education coefficient based on the semi-log form. Do the same for married coefficient. c. Describe the base group in interpreting the dummy variables. Estimate the log wage for a recent college graduate (educ = 16) with no work experience that is a married female living in a metropolitan area in the south. d. Demonstrate and explain one way to test the hypothesis that the return from living in the west region equals the return from living in the south region. e. Draw a graph using residuals that would suggest heteroskedasticity with respect to the married variable. State and explain the steps of a test for determining heteroskedasticity. -2-
