- Briefly explain Harrod-Domar model. What are the shortcomings of the model? Discuss.Consider the following model of house prices: lhprice=β0+β1bdrms+β2llotsize+β3lsqrft+u The variables are defined as: lhprice = the natural log of the house price bedrms = the number of bedrooms llotsize = the natural log of the land or lot size lsqrft = the natural log of the floor space of the house in square feet. You may assume the Gauss Markov Assumptions hold. Which of the following will make our inference on the partial effect of the number of bedrooms on the house price less precise? a) A smaller variance of any unobserved factors captured in the error term, u. b) A larger sample size. c) More variation in the number of bedrooms across the observations in the sample. d) None of the possible answers describe something that would make our inference less precise. e) A higher correlation between the number of bedrooms and the floor space of the house.Consider the following macroeconomic model: Y = C + Io + Go C = a + b(Y-T) T = d+tY Where the endogenous variables are Y, C and T, while the exogenous variables are G₁ and I. The parameters are such that a > 0,d>0,0Explain in detail what are Computable General Equilibria Models?10.14 Total economic output in three years. The n - vector xt denotes the economic output of a country in n different sectors, in yeart. An economist models the economic output using a linear dynamical system model xt+1 = Axt, where A is an n \times n matrix. Assuming her model is correct, find an expression for the total economic output in yeart + 3, in terms of xt and A. (The total economic output is the sum of the economic output in the n sectors.)Use the following versions of the IS-LM model to answer all sections: Question: a. Determine the IS function and its slope. b. Determine the LM function and its slope.You have collected data for 104 countries to address the difficult questions of the determinants for differences in the standard of living among the countries of the world. You recall from your macroeconomics lectures that the neoclassical growth model suggests that output per worker (per capita income) levels are determined by, among others, the saving rate and population growth rate. To test the predictions of this growth model, you run the following regression: RelPersIne= 0.339 – 12.894 x n +1.397 x SK , R2 = 0.621, SER = 0.177 (0.068) (3.177) (0.229) where RelPersInc is GDP per worker relative to the United States, n is the average population growth rate, 1980-1990, and SK is the average investment share of GDP from 1960 to 1990 (remember investment equals saving). Numbers in parentheses are for heteroskedasticity-robust standard erTors. a. Calculate the t-statistics and test whether or not each of the population parameters are significantly different from zero. Is the coefficient…The accompanying table shows the average annual wage for a country, in thousands of dollars, for selected years from 1970 and projected to 2040. a. Find an exponential function that models these data, with x equal to the number of years after 1970 and y equal to the average annual wage in thousands of dollars. b. Graph the model and the data on the same axes. c. What does the model predict that the average annual wage will be in 2030? Is this interpolation or extrapolation? d. When does the model predict that the average annual wage will reach $230,000? a. The equation of an exponential function that models the data is y=. (Use integers or decimals for any numbers in the expression. Round to three decimal places as needed.) b. Graph the model on the same axis as the data. Choose the correct graph below. All graphs are shown in a [0,70,10] by [0,250,50] viewing window. OA. OB. c. According to the model, the average annual wage in 2030 will be $ thousand. (Round to one decimal place as…T. Haavelmo devised a model of the US economy for the years 1929–1941 based on the followingequations:(i) c = 0.712y + 95.05 (ii) s = 0.158(c + x) − 34.30(iii) y = c + x − s (iv) x = 93.53Here x denotes total investment, y is disposable income, s is the total saving by firms, and c istotal consumption. Write the system of equations in the form (1) when the variables appear inthe order x, y, s, and c. Then find the solution of the system.SEE MORE QUESTIONS
