Use the data in TRAFFIC2 for this exercise. 1) Run an OLS regression of prcfat on a linear time trend, monthly dummy variables, and the variables wkends, unem, spdlaw, and beltlaw. Test the errors for AR(1) serial correlation using the regression in equation (12.20). Does it make sense to use the test that assumes strict exogeneity of the regressors? 2) Obtain serial correlation–and heteroskedasticity-robust standard errors for the coefficients on spdlaw and beltlaw, using four lags in the Newey-West estimator. How does this affect the statistical significance of the two policy variables? 3) Now, estimate the model using iterative Prais-Winsten and compare the estimates with the OLS estimates. Are there important changes in the policy variable coefficients or their statistical significance?

< back to assignment attempts: 1 1 keep the highest: 1 / 2 2. determining opportunity cost juanita is deciding whether to buy a suit that she wants, as well as where to buy it. three stores carry the same suit, but it is more convenient for juanita to get to some stores than others. for example, she can go to her local store, located 15 minutes away from where she works, and pay a marked-up price of $102 for the suit: store travel time each way price of a suit (minutes) (dollars per suit) local department store 15 102 across town 30 88 neighboring city 60 65 juanita makes $42 an hour at work. she has to take time off work to purchase her suit, so each hour away from work costs her $42 in lost income. assume that returning to work takes juanita the same amount of time as getting to a store and that it takes her 30 minutes to shop. as you answer the following questions, ignore the cost of gasoline and depreciation of her car when traveling. complete the following table by computing the opportunity cost of juanita's time and the total cost of shopping at each location. store opportunity cost of time price of a suit total cost (dollars) (dollars per suit) (dollars) local department store 102 across town 88 neighboring city 65 assume that juanita takes opportunity costs and the price of the suit into consideration when she shops. juanita will minimize the cost of the suit if she buys it from the . grade it now save & continue continue without saving
