3. The components of planned aggregate spending in a certain economy are given by Consumption Function: C = 800 + 0.75(Y - T) – 2000r Planned Investment: I p = 400–3000r Government Revenue and Spending: T = 300 and G = 450 Net Export: NX = 75 where r is the real interest rate (For example, r = 0.01 means that the real interest rate is 1 percent). (1) Find the level of public saving. (2) Suppose that the real...

In a closed economy, given the following: The consumption function C = 0.8(1 – 0.25) Y + 12 The average tax rate t = 25% The level of private investment I = 26 The level of government spending G = 14 Where Y is the national income. Calculate the equilibrium level of income and output in the economy. Calculate the expenditure multiplier and show the effect of an increase in government spending and an increase in private investment. Given the...

Suppose that the consumption function is given by C = 600 + 0.8Y.
