Recall the IS-LM model. In particular, the goods-market equilibrium condition was Y = C (Y − T ) + I (r) + G, and the money-market equilibrium condition was m = L (r, Y ). Here, the exogenous variables are G (government spending), T (taxes), and m (real money supply). The endogenous variables are Y (output, or income) and r (real interest rate). C (·) is the consumption function, which is increasing in disposable income Y − T , but...

Liquidity Trap in the IS-LM Model (50 points) Consider a closed economy in which output is the sum of consumption, investment and government purchases Y = C + I + G, and where C, I and G are respectively given by C = 5000 – 2000 r + 0.8(Y– T), I = 1500 – 3000 r, and G = 2500. Note also that lump-sum taxes T are given by 1250. (a) (5 points) Recalling that national savings equals S =...
(M)0=60 Consider IS-LM model. Let the money demand function be 2-) = 60 - 20r + 4y, the consumption function be C = 12 +0.81Y - T) and the investment function be ) = 30 - 2n1 where is the real interest rate in %. Let T denote taxes, G denote government purchases, P denote the price level and MS denote the money supply. Calculate the following (Round up to TWO decimal places if needed. Enter only numbers) (1) Assume...
1. Use the Keynesian cross model and show graphically in which direction will equilibrium level of income (or output) change. For each of the following, write down the formula for the size of the change of income (i.e. write down the formula for ∆Y): (i) An increase in government purchases (ii) An increase in taxes (iii) An increase in government purchase and an increase in taxes of equal amount (Nb: You must draw a SEPARATE graph for parts (i) and...
