are true‚ false or uncertain: (a) In the presence of heteroskedasticity OLS estimators are biased as well as inefficient. (b) If heteroskedasticity is present‚ the conventional t and F tests are invalid. (c) If a regression model is mis-specified (e.g.‚ an important variable is omitted)‚ the OLS residuals will show a distinct pattern. (d) If a regressor that has nonconstant variance is (incorrectly) omitted from a model‚ the (OLS) residuals will be heteroskedastic. 2. In a regression of average wages

β(1)resplast+ β(2)avggift+ β(3)propresp+ β(4)mailyear+u+e(0). Given that there are no correlation with the explanatory variables‚ OLS estimators βs will remain constant and unbiased. This is an extension of MLR 3(zero conditional mean) which suggests that the error term u has no correlation to the βs and hence can infer that likewise ‘e’ has zero conditional mean making the OLS estimators consistent and unbiased. If we consider that e(0) does not satisfy zero conditional mean then only β0 will be biased

Isoquant - Meaning and Properties * Marginal Rate of Technical Substitution * Law of Returns to Scale Meaning An isoquant is a firm’s counterpart of the consumer’s indifference curve. An isoquant is a curve that show all the combinations of inputs that yield the same level of output. ‘Iso’ means equal and ‘quant’ means quantity. Therefore‚ an isoquant represents a constant quantity of output. The isoquant curve is also known as an “Equal Product Curve” or “Production Indifference Curve”

first lab you have learned how to operate Stata and calculate descriptive statistics. You also read a paper with an interesting research question. Self-Lab 2 covers some topics of Lecture 2 and 3. In this lab you are going to learn how to calculate OLS estimator with your own hand. Later‚ you are going to answer some conceptual questions. These concepts are used in the practice very often and you should not make mistake while using them. Understand clearly what they are by reading from internet or

Emerging in 1993‚ when Dr. Dre’s G-funk had overtaken the hip-hop world‚ the Staten Island‚ NY-based Wu Tang Clan proved to be the most revolutionary rap group of the mid-’90s -- and only partially because of their music. Turning the standard concept of a hip-hop crew inside out‚ the Wu-Tang Clan were assembled as a loose congregation of nine MCs‚ almost as a support group. Instead of releasing one album after another‚ the Clan was designed to overtake the record industry in as profitable a fashion
