The following equation describes the media housing price in a community in terms of amount of pollution
Question:
log (price) = (0 + (1 log (nox) + (2 rooms + u.
(i) What are the probable signs of (1 and (2? What is the interpretation of (1? Explain.
(ii) Why might nox [or more precisely, log (nox)] and rooms be negatively correlated?
If this is the case, does the simple regression of log (price) on log(nox) produce and upward or a downward biased estimator of (1?
(iii) Using the data in HPRICE2.RAW, the following equations were estimated:
Is the relationship between the simple and multiple regression estimates of the elasticity of price with respect to nox what you would have predicted, given your answer in part (ii)? Does this mean that - .718 is definitely closer to the true elasticity than - 1.043?
