- . Consider the macroeconomic model of a two-sector economy (i.e. no government or trade) using standard notation. Assume that the consumption function is linear, i.e. of the form: C = a +bY . It is known that when ? = 110, the value of consumption, C , is equal to 160.8, and that when ? = 170, the value of C is 207.6. (a) Determine the consumption function and derive the savings ( S ) function for the model. What is the marginal propensity to consume? (b) Determine the equilibrium level of national income when planned investment ? = 255.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.What is the Euler equation for consumption, and what is its economicinterpretation?
