AI 1 An ECON 3513 Final FALL 2015 Name: 2. (10 points) Suppose a real estate developer is using analytics to determine how commercial property development is affecting local house prices. She runs two regressions. house value = bo + b sizehouse + b income + bztaxrate + b Commerical Property housepalue = bo + b size house + b income Note that the second regression is a restricted version of the first regression that imposes two restrictions (bz = b4 = 0). Given RỪNRESTRICTED = .6, RRESTRICTED = .4, n = 89, use an F-test to test the null hypothesis that bz = b4 = 0. F 1 Name: ECON 3513 Final FALL 2015 3. (10 points) Let's suppose that you have the following specification: Yt = B. + BAX: + Ut where U, might be autocorrelated: u= put-1 +ve. Having obtained the estimates, b, and by, for B, and B1, you calculate the predicted values and residuals. You find that m=2(ez - @x-1)2 = 50 and 1(e.)2 = 100. What is the Durbin Watson test statistic? a. b. What is p? ECON 3513 Final FALL 2015 Name; 5. (10 points) The following table is taken from Knack and Keefer's 1997 QJE article, “Does Social Capital Have an Economic Payoff?". Here the authors conduct 7 different regression runs using 29 country level observations. Examine Column 1, where the dependent variable is GDP Growth. Pay particular attention to TRUST's coefficient. Is it statistically significant (the standard error is in parentheses below)? Given that trust's units are percentage pointsi, how does a 10 percentage point increase in trust affect GDP Growth? .82 The Cave Coorman 3 2.733 OLS OLS Method Dependent Growth 1980 0.082 (coefficient estimate) (0.030) (standard error) PRIMO 2.194 (632) 0.082 01030 PIAO TRUST CIVIC TRUST GDPRO 0272 za 6 Ads R$ SEX Menn, D.V. 1.82 1.45 memente estar en le permite le totis , S. 1871843 PM Nisha #** ME & it is setificate t-test
