IS–LM model - Wikipedia
Answer to The demand for money curve shows the relationship between the quantity of money demanded and A) the nominal interest rat. Relate the level of the interest rate to the demand for money . Shift of the Demand Curve: The graph shows both the supply and demand curve, with quantity of. The IS–LM model, or Hicks–Hansen model, is a macroeconomic tool that shows the To keep the link with the historical meaning, the IS curve can be said to . 1 ) Transactions demand for money: this includes both (a) the willingness to hold.
Expectations about future price levels also affect the demand for money. The expectation of a higher price level means that people expect the money they are holding to fall in value. Given that expectation, they are likely to hold less of it in anticipation of a jump in prices. Expectations about future price levels play a particularly important role during periods of hyperinflation. If prices rise very rapidly and people expect them to continue rising, people are likely to try to reduce the amount of money they hold, knowing that it will fall in value as it sits in their wallets or their bank accounts.
Toward the end of the great German hyperinflation of the early s, prices were doubling as often as three times a day. Under those circumstances, people tried not to hold money even for a few minutes—within the space of eight hours money would lose half its value! Transfer Costs For a given level of expenditures, reducing the quantity of money demanded requires more frequent transfers between nonmoney and money deposits.
As the cost of such transfers rises, some consumers will choose to make fewer of them. They will therefore increase the quantity of money they demand. In general, the demand for money will increase as it becomes more expensive to transfer between money and nonmoney accounts.
The demand for money will fall if transfer costs decline. In recent years, transfer costs have fallen, leading to a decrease in money demand. Preferences Preferences also play a role in determining the demand for money. Some people place a high value on having a considerable amount of money on hand. For others, this may not be important. Household attitudes toward risk are another aspect of preferences that affect money demand.
As we have seen, bonds pay higher interest rates than money deposits, but holding bonds entails a risk that bond prices might fall. There is also a chance that the issuer of a bond will default, that is, will not pay the amount specified on the bond to bondholders; indeed, bond issuers may end up paying nothing at all.
A money deposit, such as a savings deposit, might earn a lower yield, but it is a safe yield.
Heightened concerns about risk in the last half of led many households to increase their demand for money. Such an increase could result from a higher real GDP, a higher price level, a change in expectations, an increase in transfer costs, or a change in preferences. The reverse of any such events would reduce the quantity of money demanded at every interest rate, shifting the demand curve to the left. The Supply of Money The supply curve of money Curve that shows the relationship between the quantity of money supplied and the market interest rate, all other determinants of supply unchanged.
We have learned that the Fed, through its open-market operations, determines the total quantity of reserves in the banking system. We shall assume that banks increase the money supply in fixed proportion to their reserves. Because the quantity of reserves is determined by Federal Reserve policy, we draw the supply curve of money in Figure In drawing the supply curve of money as a vertical line, we are assuming the money supply does not depend on the interest rate.
Changing the quantity of reserves and hence the money supply is an example of monetary policy. The supply curve of money is a vertical line at that quantity. Equilibrium in the Market for Money The money market The interaction among institutions through which money is supplied to individuals, firms, and other institutions that demand money.
Money market equilibrium The interest rate at which the quantity of money demanded is equal to the quantity of money supplied. With a stock of money Mthe equilibrium interest rate is r. Here, equilibrium occurs at interest rate r. Effects of Changes in the Money Market A shift in money demand or supply will lead to a change in the equilibrium interest rate. Changes in Money Demand Suppose that the money market is initially in equilibrium at r1 with supply curve S and a demand curve D1 as shown in Panel a of Figure Now suppose that there is a decrease in money demand, all other things unchanged.
A decrease in money demand could result from a decrease in the cost of transferring between money and nonmoney deposits, from a change in expectations, or from a change in preferences.
In this chapter we are looking only at changes that originate in financial markets to see their impact on aggregate demand and aggregate supply. Changes in the price level and in real GDP also shift the money demand curve, but these changes are the result of changes in aggregate demand or aggregate supply and are considered in more advanced courses in macroeconomics. Panel a shows that the money demand curve shifts to the left to D2.
We can see that the interest rate will fall to r2.
To see why the interest rate falls, we recall that if people want to hold less money, then they will want to hold more bonds. Thus, Panel b shows that the demand for bonds increases.
The higher price of bonds means lower interest rates; lower interest rates restore equilibrium in the money market. The fall in the interest rate will cause a rightward shift in the aggregate demand curve from AD1 to AD2, as shown in Panel c.
As a result, real GDP and the price level rise. Lower interest rates in turn increase the quantity of investment. They also stimulate net exports, as lower interest rates lead to a lower exchange rate. An increase in money demand due to a change in expectations, preferences, or transactions costs that make people want to hold more money at each interest rate will have the opposite effect.
The money demand curve will shift to the right and the demand for bonds will shift to the left. The resulting higher interest rate will lead to a lower quantity of investment. Also, higher interest rates will lead to a higher exchange rate and depress net exports.
Thus, the aggregate demand curve will shift to the left. All other things unchanged, real GDP and the price level will fall. Changes in the Money Supply Now suppose the market for money is in equilibrium and the Fed changes the money supply. All other things unchanged, how will this change in the money supply affect the equilibrium interest rate and aggregate demand, real GDP, and the price level?
Suppose the Fed conducts open-market operations in which it buys bonds. This is an example of expansionary monetary policy. The impact of Fed bond purchases is illustrated in Panel a of Figure As we learned, when the Fed buys bonds, the supply of money increases. Panel b of Figure At the original interest rate r1, people do not wish to hold the newly supplied money; they would prefer to hold nonmoney assets. To reestablish equilibrium in the money market, the interest rate must fall to increase the quantity of money demanded.
The interest rate must fall to r2 to achieve equilibrium.
The lower interest rate leads to an increase in investment and net exports, which shifts the aggregate demand curve from AD1 to AD2 in Panel c. Real GDP and the price level rise. The reduction in interest rates required to restore equilibrium to the market for money after an increase in the money supply is achieved in the bond market. The increase in bond prices lowers interest rates, which will increase the quantity of money people demand. Lower interest rates will stimulate investment and net exports, via changes in the foreign exchange market, and cause the aggregate demand curve to shift to the right, as shown in Panel cfrom AD1 to AD2.
Consumers and businesses have a demand for money, including cash and checking and savings accounts, and they use financial institutions for this purpose. Economists illustrate money demand using a demand curve, just like they do in the market for products and services.
Money Demand and Money Supply Curves The demand curve for money illustrates the quantity of money demanded at a given interest rate. Notice that the demand curve for money is downward sloping, which means that people want to hold less of their wealth in the form of money the higher that interest rates on bonds and other alternative investments are. The central bank controls the supply of money, and they interact with other financial institutions. This interaction is part of the money market, and we can illustrate it using a supply curve.
The supply curve for money illustrates the quantity of money supplied at a given interest rate, and here's what that looks like. Notice that unlike a typical supply curve in the product market, the supply curve for money is vertical, because it does not depend on interest rates.
It depends entirely on decisions made by the central bank. The supply of money is determined outside the model.
The nominal stock of money M is determined by the monetary authorities, with price level assumed to be constant at the level P. Equilibrium in the Money Market: As a result, price of bonds will increase. As the price of bonds and interest rate are inversely related, therefore when price of bonds rises, interest rate decreases till the equilibrium point E is not reached. To attract funds the banks will increase the interest rate till the equilibrium point E is not reached.
By selecting arbitrary interest rates and finding income level which is consistent with money market equilibrium, we derive the LM curve which is positively sloped. The LM curve shows different income levels at different interest rates where demand for money is equal to the supply of money at a given nominal money supply and given price level.

Corresponding demand curve for real balances is L0, which is downward sloping because demand for real balances L2 is a decreasing function of the interest rate. Therefore, E1 is an equilibrium point in the money market. By plotting combination of interest rate i1 and income level Y1 we get a point E1 on the LM curve. Therefore, income level increases.
Thus, increase in interest rate is accompanied by an increase in the income level.
