7. Consider the following income-expenditure model of a closed economy. The aggregate consumption function is C = 100 +0.8(Y – T); taxes are T = 380; investment, I, is 300 and government expenditure, G, is 200.

( a)Calculate the multiplier, equilibrium income and the government budget surplus [6 marks]

(b)Now let taxes, T = 10 + 0.25Y. Recalculate the multiplier, equilibrium income and the government budget surplus. Try to explain any differences between your answers and your answers to part (a). [10 marks]

( c)Now we further extend the model and open the economy to trade. Let net exports be NX = 444 - 0.3Y. Keep the tax function as in (b). Recalculate the multiplier and equilibrium income and again explain any differences between your answers and those in part (b). [10 marks]

Consider a closed economy where aggregate expenditure is AE = C + I + G. Government purchases (G) is a constant, which do not vary with output level (Y). Consumption (C) is an increasing function of disposable income YD: C = a + bYD. In this economy, we have lump sum tax only; YD = Y –T. Investment is an increasing function of Y: I = k + iY. 1. The equilibrium condition is Y = AE. Solve for the...

Consider a closed economy income-expenditure model of the economy where the country begins in a long-run equilibrium. • Investment (I) and government spending (G) are fixed: I = 41.5, G = 26. • The income tax rate is t = 6.25%, so tax revenue equals T = tY . • The consumption function is C = 12 + 0.8Yd, where Yd = (1 − t)Y . For the calculations below, write your answers as either a fraction or to two...

In a hypothetical economy, the aggregate consumption expenditure is given by C = 20 + 0.6Yd , where Yd is the real disposable income. In the current quarter, the net tax is T = 60, and the investment expenditure is I = 30. Government budget is balanced, meaning that the government expenditure is G = 60. Finally, net exports is N X = 0. All these variables are real values. We hold the price level fixed. Assume that, given a...

Consider the Aggregate Expenditure Model (AKA the Multiplier Model where prices are fixed) for a closed private economy.  What are the categories of expenditure? What determines the slope of the AE function? Why is the intersection of the AE and the 45-degree line the equilibrium? To answer the last part tell me what is happening with inventories if you are at a GDP level below the equilibrium and why that pushes the economy toward equilibrium. What are the leakages and injections...

6. 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 = 45+0.75×(Y – T) Suppose G = $60 billion, I = $60 billion, and T = $20 billion. Given the consumption function and the fact that for a...
