Completely analyse the following demand equation for Hyundai sedan vehicles Qx = 8.2 - 0.82Px - 2.08Py + 3.26Pb + 0.68Y (3.36) (0.311) (0.745) (2.98) (0.137) R2 = 0.936; Level of significance = 5%; n = 65; figures in brackets are the standard errors Where, Qx = The quantity of Hyundai vehicles demanded; Px = The price of Hyundai sedan vehicles; Py = The price of fuel; Pb = The price of BMW sedan vehicles; Y = The average household income (in thousands of dollars) A. Interpret the estimated coefficients (8 marks) B. Interpret whether each estimated coefficient, including the intercept, is statistically significant. Hence state which explanatory variables have any real effects on demand for Hyundai sedan vehicles. (12 marks) C. Determine the goodness of fit of the regression equation and evaluate your results. (5 marks)A. Use one disequilibrium theory and one compensatory theory to explain why economic profits vary amongst firms? (5 marks) B. Explain with examples, the three different forms of price discrimination. (6 marks) C. If we were told that the estimated production function for particular vials of vaccine Q = 3K 0.8 L 0.2 Where Q = millions of vials of vaccine K = units of capital (000) L = person hours (000) If the cost of labour (L) is $30 per person hours and capital (k) costs $20 per unit, i. In what ratio must K and L be used in order to produce this vaccine at the lowest possible cost? (11 marks) ii. Based on the results, which is more productive, labour or capital? (2 marks) iii. Is the production process more labour or capital intensive? (1 mark)
