If the price level rises, the LM curve shifts left. This occurs because people need more money to pay the higher prices, but the higher resulting interest rates lower the demand for money. If the price level declines, the LM curve shifts right.
Full Answer
What will shift the IS curve?
What happens if both curves shift at the same time?
How does an increase in money supply affect the rate of interest?
What happens to the demand for money in the money market?
How does monetary policy help the economy?
What shifts the IS and LM curve?
Any fiscal policy change (a change in government expenditure or taxes) will shift the IS curve. Similarly, any monetary policy change will shift the LM curve.
What shifts LM curve to the right?
Monetary stimulus, that is, increasing the money supply, causes the LM curve to shift right, resulting in higher output and lower interest rates. Fiscal stimulus, that is, increasing government spending and/or decreasing taxes, shifts the IS curve to the right, raising interest rates while increasing output.
What causes the IS curve to shift to the left?
Any change (decrease in government consumption, increase in taxes, decrease in consumer confidence - proxied by c0) that, for a given interest rate, decreases the demand for goods creates a shift of the IS curve to the left.
What happens to LM curve when inflation rises?
(b) The rise in expected inflation shifts the LM curve down and to the right, as shown in Figure 9.22. The price level rises, shifting the LM curve up and to the left to restore equilibrium. Since the real interest rate is unchanged, consumption and investment are unchanged.
Why is LM curve upward sloping?
The LM curve slopes upward because higher levels of income (GDP) induce increased demand to hold money balances for transactions, which requires a higher interest rate to keep money supply and liquidity demand in equilibrium.
In which case LM curve is horizontal?
If the demand for money is very sensitive to the interest rate, then the LM curve is close to horizontal. In that case, a small change in the interest rate is accompanied by a large change in the level of income to maintain money-market equilibrium.
What shifts the FE curve?
Factors That Shift the IS Curve. • For constant output, any change in the economy that reduces desired national saving relative to desired investment will increase the real interest rate that clears the goods market and, thus, shift the IS curve.
Which changes can cause a leftward shift in the demand curve?
In case of complementary goods demand for the commodity falls with a rise in the price of complementary commodity. iii Tastes and Preferences: If consumers tastes and preferences change against the commodity the quantity demanded of the commodity falls implying a shift in demand curve to the left.
Does inflation shift the IS curve?
Since the IS curve depends on the real interest rate rather than the nominal interest rate, an increase in expected inflation causes the IS curve to shift inwards in the short-run.
What happens when LM curve is vertical?
b) If money demand does not depend on the interest rate, the LM curve is vertical. The LM curve represents the combinations of income and the interest rate at which the money market is in equilibrium. If money demand does not depend on the interest rate, then we can write the LM equation as M/P = L(Y).
Why does LM curve slope downward?
It slopes downward because, as the price level increases, the LM curve shifts left as real money balances fall. AD shifts in the same direction as the IS or LM curves, so anything that shifts those curves shifts AD in precisely the same direction and for the same reasons.

Shift in IS curve and its Effect on Equilibrium Income
According to the Keynesian theory, for a given rate of interest, changes that occur in consumption level, business investment level, government expenditure, and taxes shift the aggregate demand function and bring changes in the level of equilibrium output.
Why does the LM curve shift to the left?
This is because, greater demand for money, given the supply of money, will raise the rate of interest corresponding to each level of national income.
What is the IS-LM curve?
The IS-LM curve model emphasis es the interaction between the goods and money markets. The goods market is in equilibrium when aggregate demand is equal to income. The aggregate demand is determined by consumption demand and investment demand.
Why does the LM curve slope upward?
This is because with higher levels of income, demand curve for money (M d) is higher and consequently the money- market equilibrium, that is , the equality of the given money supply with money demand curve occurs at a higher rate of interest. This implies that rate of interest varies directly with income.
Where does the LM curve come from?
The LM curve can be derived from the Keynesian theory from its analysis of money market equilibrium. According to Keynes, demand for money to hold depends upon transactions motive and speculative motive.
How is the level of national income determined in Keynes's model?
In other words, in Keynes’ simple model the level of national income is shown to be determined by the goods market equilibrium. In this simple analysis of equilibrium in the goods market Keynes considers investment to be determined by the rate of interest along with the marginal efficiency of capital and is shown to be independent of the level of national income.
How does interest affect aggregate demand?
When the rate of interest falls the level of investment increases and vice versa. Thus, changes in the rate of interest affect aggregate demand or aggregate expenditure by causing changes in the investment demand. When the rate of interest falls, it lowers the cost c’ investment projects and thereby raises the profitability of investment.
Which model is based on the Keynesian framework?
According to him, the level of income which depends on the investment and consumption demand determines the transactions demand for money which affects the rate of interest. Hicks, Hansen, Lerner and Johnson have put forward a complete and integrated model based on the Keynesian framework wherein the variables such as investment, national income, rate of interest, demand for and supply of money are interrelated and mutually interdependent and can be represented by the two curves called the IS and LM curves.
When does the LM curve shift?
If the central bank (or Federal Reserve) decides to increase the money supply (by buying t bills) then the LM curve shifts right.
Why does the LM curve shift right?
If improvement in the velocity of money occurs such that people require less money to conduct all of their transactions, the LM curve will shift right (because the opportunity cost of holding money goes down because there is now an alternative).
What happens to the LM curve when the price level rises?
If the price level rises, the LM curve shifts left. This occurs because people need more money to pay the higher prices, but the higher resulting interest rates lower the demand for money. If the price level declines, the LM curve shifts right.
Does a decrease in imports shift right?
However, depending on your professor, a change in imports will have the opposite effect on the IS curve that exports has, so a decrease in imports shifts IS right, and an increase shifts IS left. If consumers/firms feel more confident about the future, they may invest more regardless of the interest rate.
How does a change in the money supply affect the LM curve?
The money supply is held constant along the LM curve. It follows then that a change in the money supply shifts the LM curve. This point is illustrated in Fig. 38.7. An increase in the quantity of money in circulation shifts the supply curve of money to the right in part (b)—from M 1 to M 2.
How does the IS curve shift?
4. The IS curve is shifted by changes in autonomous spending. An increase in autonomous spending, such as investment spending or government expenditure, shifts the IS curve to the right.
What is the equilibrium schedule of the goods market?
The goods market equilibrium schedule is the IS curve (schedule). It shows combinations of interest rates and levels of output such that planned (desired) spending (expenditure) equals income.
Why is the IS curve sloped?
The IS curve is negatively sloped because a higher level of the interest rate reduces investment spending , thereby reducing aggregate demand and thus the equilibrium level of income. The steepness of the curve depends on the interest elasticity of investment (i.e., how sensitive investment spending is to changes in the interest rate) as also on the (investment) multiplier.
Why is the IS negatively sloped?
The IS is negatively sloped because an increase in the interest rate reduces planned (desired) investment spending and therefore reduces aggregate demand, thereby lowering the equilibrium level of income.
When does the equilibrium level of income change?
The equilibrium levels of income and interest rate change when either the IS curve or the LM curve shifts to a new position (either to the right or to the left). Fig. 38.10, for example, shows the effects of an increase in autonomous spending (such as autonomous investment) on the equilibrium levels of income and the interest rate. An increase in autonomous spending shifts the IS schedule to the right.
What is the position of the IS curve?
The position of the IS curve depends on the level of autonomous spending. If autonomous spending increases, the IS curve will shift to the right (with or without a change in slope, depending on interest elasticity of investment).
The IS-LM Diagram
The IS-LM diagram gives us a simple framework to understand Keynesian theory once you have mastered the concepts behind it - but again, you'll need to read my other pages to get the background information on that.
A Few Historical Notes
Keynes had been in favor of fiscal policy management to achieve the desired level of income/output, and that preference related to the international exchange rate system of the day, but for most of the last four or five decades the preferred policy tool has been monetary policy.
What changes the LM curve?
Monetary policy changes such as purchase or sale of bonds by the central bank or changes in discount rate, etc. also shift the LM curve. If there is a monetary expansion i.e. increase in money supply, the LM curve shifts outwards and it increases output.
What shifts the LM curve inwards?
A monetary contraction, on the other hand, shifts the LM curve inwards, from LM1 to LM2.
Why does the IS curve slope downward?
The IS curve slopes downward because an economy’s output is higher at lower interest rate and vice versa. The LM curve slopes upwards because when output level is higher there is higher demand for money which causes interest rates to be higher. As shown by the graph above, the interplay of IS curve and LM curve determines ...
Why does the IS-LM model apply to short-run?
IS-LM model applies to short-run because it assumes prices are sticky. It means that the IS-LM model assumes that prices, wages and money supply are given and do not change. The model offers a very useful explanation of the short-run fluctuations because stickiness of prices and wages is indeed the case in the short-run.
Where does the new short run equilibrium occur?
The new short-run equilibrium occurs at the point of intersection of the new IS and LM curves.
Who developed the IS-LM model?
IS-LM model was initially developed in 1937 by John Hicks based on works of John Maynard Keynes. An extension of the IS-LM model which integrates the net exports part of aggregate demand with domestic goods market and financial market is called Mundell-Fleming Model or IS-LM-BoP model.
What determines the interest rate and output level that prevails in an economy?
As shown by the graph above, the interplay of IS curve and LM curve determines the interest rate and output level that prevails in an economy.
What is LM curve?
The LM curve represents a “ [positive] relationship between the interest rate and the level of income (while holding the price level fixed) that arises in the market for real money balances.” (Mankiw, 2010) LM stands for liquidity and money, in which the rate of interest can influence investment and demand for money. LM curve represents the supply and demand for money, and LM shocks are also exogenous changes only now for the demand of money. An LM shock could be a change in a change in reserve requirements, a change in accessibility to banks/ATMs.
How does changing the money supply affect the LM curve?
Now, the effects of changing the money supply on the LM curve are shifts. “Decreases in the supply of real money balances shift the LM curve upward [while, increases] in the supply of real money balances shift the LM curve downward.” (Mankiw, 2010)
How does the LM curve shift?
The LM curve shifts when there is a change in monetary policy. Central banks, such as US Federal Reserve Bank, change money supply mainly through open market operations, changes in reserve ratio, discount rate, etc. In reality, central banks actually attempt to take the financial market to a specific equilibrium interest rate.
What is LM curve?
LM curve is derived from a schedule of equilibrium output/GDP that correspond to different interest levels. It represents the snapshot of the financial market i.e. the prevailing interest rate at different output levels.
Why does the LM curve slope upward?
It slopes upward because high output/GDP is associated with high interest rate due to high demand for money and vice versa.
What is the intersection of money demand curve and money supply curve?
As shown in the graph below, r1, the intersection of money demand curve and money supply curve shows the equilibrium interest rate.
What is monetary expansion?
A monetary expansion is when a central bank purchases bonds from banks, decreases reserve ratio, etc. When money supply curve shifts outward, market interest rate falls and the LM curve shifts outward. It is because due to higher supply of money, a higher output is possible at the same interest rate.
Why do people keep more money when interest rates are low?
When the interest rate is low, people keep more money because they prefer liquidity and it is cheaper to hold money. As soon as the interest rate increases, people reduce their cash in hand because it is costly (opportunity cost-wise) to do so. It is why the money demand curve slopes downward.
Why is the IS curve higher?
It is because due to higher supply of money, a higher output is possible at the same interest rate. The opposite occurs in a monetary contraction. Similarly, fiscal policy changes such as changes in government spending and taxes shift the IS curve.
What are the two main factors that affect the LM curve?
The two main factors that affect the LM curve include change in demand for money and change in supply of money.
What is the theory of autonomous change in money demand?
Autonomous Changes in Money Demand. The theory of asset motive states that there can be an autonomous rise in the demand for money. This means that no change occurs in the money demand even due inflation, deflation, interest rates, or the level of aggregate output/income.
What happens when money supply declines?
On the other hand, a decline in money supply will lead to the leftward shift of the LM curve. When the government follows a contractionary monetary policy, supply of money in the economy declines. Under a tight monetary policy, the central bank raises the bank rates, makes sale of securities in the open market, and increases the RRR requirements as well.
What happens when the central monetary authority of the government or the country adopts an easy expansionary monetary policy?
When the central monetary authority of the government or the country adopts an easy expansionary monetary policy, the supply of money increases in the economy and the LM curve shifts right. Expansionary or easy monetary policies include lower bank discount rates, purchase of securities in open market, and reduction in required reserve ratio (RRR).
How to eliminate excess demand of money?
The condition for excess demand of money in the market can only be eliminated by increasing the interest rate, which reduces the quantity of money demanded, until it reaches a point where supply of money is equal to demand of money.
What will shift the IS curve?
Any fiscal policy change (a change in government expenditure or taxes) will shift the IS curve. Similarly, any monetary policy change will shift the LM curve.
What happens if both curves shift at the same time?
If both curves shift at the same time, the consequence is unpredictable Consider Fig. 17. If IS curve shifts to the right and LM curve to the left the rate of interest increases (from r 0 to r 1 ), but income remains unchanged (at Y e ). Alternatively, if both shift to the right, the rate of interest remains unchanged (at r 0 ), but the level of income rises (from Y 0 to Y 1 ).
How does an increase in money supply affect the rate of interest?
An increase in money supply shifts the LM curve to toe right and reduces toe rate of interest. This raises investment in the commodity market. Income consequently rises. Similarly an increase in the demand for money, for instance, raises the rate of interest by shifting the LM curve leftward (Fig.16); investment falls and so income.
What happens to the demand for money in the money market?
The demand for money is reduced in the money market and as a consequence toe rate of interest falls . So, at the end the rate of interest and the level of income both fall. Conversely, a reduction in taxes or an increase in government expenditure or both fall.
How does monetary policy help the economy?
Monetary policy can neutralise the adverse effects of fiscal policy and bring about the desired change in the economy. We can also think of other possibilities. Thus, by making appropriate use of monetary and fiscal measures it is possible to achieve the desired goals of the economy such as full employment and price level stability. See table below.
