478 Exam 1 Spring 2008 A R E C / E C O N 4 7 8 P R O F . L U E C K E X A M I S P R I N G 2 0 0 9 1. EMPIRICAL ANALYSIS [20 points] A recent empirical study estimates the determinants of potential state carbon tax revenues using the equation Y = α + β 1 X 1 + β 2 X 2 + β 3 X 3 + ε , where β i is the estimated coefficient for variable X i and Y is the amount the tax revenues (in $millions) per year. The variables X 1 through X 3 are: the tax on CO2 emissions; the price per barrel of oil ($); and the state’s per capita income (in $1,000s/year). The table below shows the estimated coefficients ( β s) from a regression analysis using data from all 50 states for a single year. Assume that all of the estimated coefficients have a low enough variance (standard error) so they are statistically significant. Answer the specific questions below. Independent Variables Estimated coefficients X 1 TAX RATE ($ per ton of CO2) 12.02 X 2 PRICE OF A BARREL OF OIL ($) -2.44 X 3 PER CAPITA INCOME ($1,000s/year) -10.05 (A) Does the evidence support the hypothesis that higher carbon tax rates lead to a reduction in state tax revenues? (B) How much will tax revenues change if the price of oil goes down by $10 per barrel? (C) Does higher average income increase tax revenues? *** PUT YOUR NAME ON THE BACK ONLY.

478 Exam 1 Spring 2008 4. BUREAUCRACY VS. ENVIRONMENT? [20 points]. Consider a tract of forest land with two uses: commercial timber (T) and wildlife habitat (W). W and T are both measured in acres, so the total land area is W + T. The graph below shows the demand curves (net of production costs) for both uses in terms of land area. The horizontal axis is the total amount of land (W+T) in the tract. (A)
