please show all the steps and work to solve the problem, but also please visually emphasize your final answer.(e.g. by putting a box around).
(a) The IS Curve is given by the goods-market equilibrium equation. We know that it is given by
where C = Consumption as a function of disposable income Y-T
I = Investment as a function of Interest rate
G = Government Spending
Given that G, T(Taxes) are exogenous.
Let us assume the following Consumption and Investment functions:
where b = Marginal Propensity to Consume, 0<b<1
a, b, j, k >0
We now have the IS equation as:
Rearranging to collect constants, endogenous and exogenous terms, we get:
where A = (a + j +G - bT)
Taking total differential, we get
The negative sign means that the IS Curve is negatively sloped, i.e. Y and r are negatively related.
(b) The LM Curve is given by the money-market equilibrium equation. We know that it is given by
m = L(Y, r)
We know that money income is positively related to Y and negatively related to r. So we have the following equation for the money market
where m (real money supply) is exogenous.
Rearranging and expressing in terms of r, we get:
Taking total differential, we get
The positive sign means that the LM Curve is positively sloped, i.e. Y and r are positively related.
(c) We have already derived the IS equation above
Differentiating with respect to G, we get:
(d)
Differentiating with respect to T, we get:

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...
1. (26 marks total) Math Review: Recall the IS-L.M model from your intermediate macro course In particular, the goods-market equilibrium condition was Y-C(Y-T)+I (r) +G, and the money-market ecluilibrunn 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, bit less than one-for-one...
Need help, please show work Blank options for B, E, and F are either 'steeper or flatter." Blank options for C are "decreases in taxes or increase in govt purchases." This problem asks you to analyze the IS-LM model algebraically. First the consumption function and investment function from the goods market will be examined. Then, the money demand function from the money market will be examined. The Goods Market: Suppose consumption is a linear function of disposable income: C(Y- Ta...
OY 10. By referring to Figure 7-1, an increase in the money stock a shifts the LM schedule to the right from LMoto LM b shifts the LM schedule to the left from LMo to LM e leaves the LM curve unchanged at LM. d. shifts neither the IS nor the LM schedule. 11. Changes in all of the following shift the LM curve except a. the price level. b. income. c. the money supply. d. money demand. e. all...
1. (The IS-LM-PC model): Assume the following relations characterize the goods market: (i) 1128 +0.2Y 300(rt + xt) (iii)G,-215 :T t = 200 (iv)st= 0.15 or 15% e) Derive the IS curve (as a relation between Y and r). (b) Assume the LM curve is given by r 0.16 (ie. in period t, the central bank sets the real interest rate at 16%). What is the short-run equilibrium level of output (Yt )? (c) Suppose that L = 2000 and...
Question 2: Money market Suppose that the money demand function is (M/P) = 0.75 Y - 200r The money supply M is 6000 and the price level is 2. a. Graph the supply for real money balances on a new graph (label it "figure 3"), and label the supply of real money balances (M/P). g. Suppose that the income is 6000. Complete Table 1 and draw the demand for real money balances curve ((M/P'] in figure 3. Find the value...
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...
Consider the following short-run model of equilibrium in the foreign exchange market, money market, and goods market: (1) R=R∗+Ee−EE, (2) MsP=L(R,Y), (3) Y=C(Y−T)+I+G+CA(q,Y−T). All variables have the interpretation given in class (in particular, q=EP∗P is the country's real exchange rate). Suppose that the government increases temporarily its spending by ΔG. a) Explain how the endogenous variables of this model adjust to the new short-run equilibrium. b) Suppose now that the government combines the temporary increase in government spending with a...
My question is d and e Please details thank you d. Assume that G increases by 200. By how much will Y increase in short-run equilibrium? What is the government-purchases multiplier (the change in Y divided by the change in G)? e. Assume that G is back at its original level of 1,000, but M (the money supply) increases by 200. By how much will Y increase in short-run equilibrium? What is the multiplier for money supply (the change in...
