Suppose that a coffee producing firm estimated the following regression of the demand for its brand of coffee: 𝑄𝐶 = 3 − 6𝑃𝐶 + 1.6𝑌 + 4.0𝑃𝑏 − 1.2𝑃𝑆 + 2.4𝐴 Where 𝑄𝐶 = Sales of coffee brand C in KSH per Kilogram; Y = Personal disposable income in thousand KSH per year; 𝑃𝑏 = Price of the competitive brand of coffee in KSH per Kilogram; 𝑃𝑆 = Price of Sugar in KSH; and A = Advertising expenditures for coffee brand C in thousands of KSH. Suppose also that this year, Pc = Ksh.4, Y = Ksh.5, Pb = Ksh.3.6, PS = Ksh.2, and A = Ksh.2 (i) Interpret the results of the estimated demand (4 Marks) (ii) Compute point price elasticity of demand for the firm’s brand of coffee with respect to its price (iii) Compute the cross elasticity of demand for coffee with respect to the price of the competitive coffee brand b (2 Marks) (iv) At current price level, would it be viable for the firm to increase the price level of its brand of coffee? Support your answer by showing all relevant calculations. (3 Marks) (v) Would you recommend that the firm continues to advertise its product?
