Behavioural and Structural equations of an economy are given below: C         =          200 + b (Y – 100 – tY) I           =          100 G         =          100 X         =          20 M         =          10 + 0.1Y The marginal propensity to consume ‘b’ is equal to 0.8 and proportional income tax rate, t = 0.25. Find the equilibrium national income; Find the value of foreign trade multiplier & equilibrium value of imports If equilibrium national income falls short of full employment income by Rs100, how much government should increase its expenditure to attain full – employment?

a) Calculate the national income equilibrium. b) Based on your answer in (a), show the aggregate expenditure graph. c) Explain what would happen to the national income equilibrium if the investment changes by RM100 million.

Assuming that there is no government spending or trade, an economy’s GDP is the sum of domestic consumption C and investment I, i.e. Y = C+ I Assume that I is unaffected by GDP Assume the consumption function is C = c0 + c1Y In any equilibrium aggregate demand, AD must be equal to Y, GDP. Given this model, which FIVE of the following statements are correct?   Select one or more: A. If the economy above is a demand-driven economy, then the equilibrium solution for Y is given by Y = m(c0 + I), where m = 1/(1 - c1) is the multiplier. B. if c1 = 0.8 the multiplier is equal to 1/0.8= 1.25 C. if c1 = 0.75 the multiplier is equal to 4 D. assume c0 =100, I=50, c1=0.6. The equilibrium value of Y in a demand-driven economy is 300. E. Assume that Y is initially 400, I is initially 100, and the multiplier is 2.5. I increases by 10%. The multiplier implies that in equilibrium Y will increase by 25%. F. The higher is c1 the larger is the multiplier G. If consumers…

For a income determination model Y = C +I + G, C = Co + bY d, I = Io + aYd, Yd = Y – T, T = To +tY, G = Go, 0 < a, b, t < 1, find the equilibrium level of income. Find the multipliers for each input.
