- Given the following consumption function, C = 400 + 0.75YD,where C= consumption expenditure, YD = disposable income, Investment= $1200, Government spending = $1600,Exports = $500, Imports = $600, Taxes = $1200 and Potential GDP = $9000Choose corrcct optiona) Aactual output is less than potential outputb) actual output is zeroc) actual output is equal to potential outputd) actual output is higher than potential output5. Algebra of the income-expenditure model Consider a small economy that is closed to trade, so its net exports are equal to zero. Suppose that the economy has the following consumption function, where C is consumption, Y is real GDP, / is investment, G is government purchases, and T is for net taxes: C 40+0.5x (Y-T) Suppose G $265 billion, 7- $50 billion, and T $10 billion. Given the consumption function and the fact that, in a closed economy, total expenditure can be calculated as Y = C+I+G, the equilibrium output level is s billion. Suppose the government purchases are reduced by $100 billion. The new equilibrium level of output will be equal to s billion. Based on the effect of the change in government purchases on equilibrium output, you can tell that this economy's spending multiplier is equal to8. The income-expenditure model Consider a small economy that is closed to trade, so its net exports are equal to zero. Suppose that the economy has the following consumption function, where C is consumption, Y is real GDP, I is investment, G is government purchases, and T stands for net taxes: C = 15+0.75 x (Y-T) Suppose G = $90 billion, 1 = $60 billion, and T = $20 billion. Given the consumption function and the fact that for a closed economy total expenditure can be calculated as Y=C+I+G, the equilibrium output level is equal to 5 billion. Suppose the government purchases are increased by $50 billion. The new equilibrium level of output will be equal to Based on the effect of the change in government purchases on equilibrium output, you can tell that this economy's spending multiplier is equal to

Find consumption expenditure from the following National Income =Rs. 5000 Autonomous Consumption = Rs. 1000 Marginal Propensity to Consume = 0.8 %3Dn an effort to make sales projections, M/s K, B and A, the three B-school executives of Vengaboys Inc., were discussing about the national income and its growth in Ibiza. K had estimated a linear consumption function for Ibiza to be C = 100 + 0.6 Y, and investment to be I = 100 per ear. In Ibiza, there was no income tax and government spending was minimal (assume 0). Ibiza was a closed economy, and hence no exports and imports. (i)K immediately knew what the investment Multiplier was. Can you find out? (ii)What is the level of income in Ibiza? (iii)K estimated that with Government spending 100 on a new road to be constructed, the income levels are sure to go up. K quickly calculated the change in income and the new income level to be:3.
