Assignment-log linear model with dummy variable regressor A least squares regression model explaining the sample variation of LOGEARN,, the logarithm of reported weekly earnings for individual i, yields the estimated Bivariate Regression Model LOGEARN = 5.99+ .383 gender, + U₁ where gender, is a dummy variable which is, in this case, one for females and zero for males. The issue of how to evaluate the precision of the parameter estimates in a model such as this will be discussed in Chapters 6 and 7: you may ignore these issues in answering this question. a. What interpretation can be given to this estimated coefficient on the variable gender,? In particular, what can one say about how the expected value of the logarithm of weekly earnings depends on gender? b. What can one say about how the expected value of household earnings itself depends on gender? c. Suppose that it becomes apparent that females are, on average, better educated than males. Presuming that well-educated individuals…
(Don't accept answers from Chat-GPT)You are estimating the following simple linear regression model: Edui = B0 + B1 MomEdu + ui. Where Edu is the years of schooling of an individual and MomEdu is the years of education of the individual's mother (Note: We might estimate this sort of regression to learn about intergenerational transmission of economic success.) a. Suppose you restrict your sample to individuals with MomEdui = 10 What happens to the OLS estimates? b. Suppose you have two random samples of size 100, both with the same In the first sample, half of the mothers have 12 yearsof education and half have 14 years of education. In the second sample, one quarter of of the mothers have each of 10, 12, 14. and 16 years of education. Does the variance of the OLS estimator differ between the two samples? Explain why or why not. C. Suppose you estimate the above regression using a random sample of 100 observations. Then you find another random sample of 100 with the same as the…

The index of industrial production (IP) is a monthly time series that measures the quantity of industrial commodities produced in a given month. This problem uses data on this index for the United States. All regressions are estimated over the sample period 1986:M1 to 2017:M12 (that is, January 1986 through December 2017). Let Ye=1200 x In(IP/IP-1). Suppose that a forecaster estimates the following AR(4) model for Ye Ŷ=0.749 +0.071Y1 + 0.170Y 2 + 0.216Y 3 + 0.167Y(-4 (0.488) (0.088) (0.053) (0.078) (0.064) The forecaster wants to use this AR(4) to forecast the value of Ye in January 2018, using the following values of IP for July 2017 through December 2017: Date IP 2017:M7 2017:M8 2017:M9 2017:M10 2017:M11 2017:M12 105.01 104.56 104.82 106.58 106.86 107.30 The forecast value is a.
