The LM curve shifts to the right when the stock of money supply is increased and it shifts to the left if the stock of money supply is reduced. At all points to the right of the LAI curve, there is an excess demand for money, and at points to its left, there is an excess supply of money. As the economy expands, banks and other financial institutions need funds to support the extra investment. To get those funds, they encourage consumers to deposit more of their cash into longer term deposits like certificates of deposit or bonds.

In a closed economy, in the goods market, a rise in interest rate reduces aggregate demand, usually investment demand and/or demand for consumer durables. This lowers the level of output and results in equating the quantity demanded with the quantity produced. This condition is equal to the condition that planned investment equals saving. The negative relationship between interest rate and output is known as the IS curve. Panel C shows that a monetary expansion shifts the LM curve downwards.

Therefore, when the money supply increases, given the money demand function, it’ll lower the rate of interest at the given level of income. This is often because with income fixed, the speed of interest must fall so that demands for money for speculative and transactions motive rises to become equal to the greater money supply. This will cause the LM curve to shift outward to the right. Despite many shortcomings, the IS-LM model has been one of the main tools for macroeconomic teaching and policy analysis. The IS-LM model describes the aggregate demand of the economy using the relationship between output and interest rates.

And we’ve derived the LM curve from a family of demand curves for money. As income increases, money demand curve shifts outward and thus the rate of interest which equates supply of money, with demand for money rises. If the central bank controls the interest rate, the equilibrium level of income moves along the IS curve.

The article owes a great deal to comments and suggestions received from Pulapre Balakrishnan, whose help the author gratefully acknowledges. He also wishes to thank Ashoka University for the excellent infrastructural facilities it provided during his visit. Supply-siders are criticised for their policy of non-intervention by the state.

The resulting IS curve will slope downward from left to right as shown. The IS — LM model continues to be used (since its introduction in 1939 by J. R. Hicks) for macro- economic studies. The main reason is that it provides a simple and appropriate framework for analysing the effects of monetary and fiscal policy changes on the demand for output and interest rates. 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.

In fact, supply sides contend that many taxes constitute a wedge between the costs incurred on resources and the price of a product. With the substantial growth of the public sector, the funds required to finance it have greatly increased resulting in a greater tax wedge. This has worked to shift the aggregate supply curve to the left.

This will shift IS schedule to the right, and given the LM curve, the rate of interest also as the level of income will rise. It therefore follows from above that increase within the money demand function causes the LM curve to shift to the left. Similarly, on the contrary, if the money demand function for a given level of income declines, it’ll lower the rate of interest for a given level of income and can therefore shift the LM curve to the right. Points above and to the left of the curve correspond to an excess supply of money; points below and to the right, to an excess demand for money.

Further, supply-side economics stresses the determinants of long-run growth rather than causes of short-run cyclical changes within the economy. Supply-side economists lay emphasis on the factors that determine the incentives to figure, save and invest which ultimately determine the aggregate supply of output of the economy. Against this backdrop an alternative school of considered macroeconomics was put forward. This alternative thought laid stress on supply-side of macroeconomic equilibrium, that is, it focused on shifting the mixture supply curve to the right rather than causing a shift in aggregate demand curve. The government plays a limited role in liberalising markets, reducing taxes and freeing the labour market.

  • The LM curve comprises combinations of the interest rate and income, for which the money market is in equilibrium.
  • Following Robert Lucas’s Nobel lecture, the merits of economic policies that assume the form of random shocks to an economic system are questioned.
  • The first important basic proposition of supply-side economics is that cut in marginal tax rates will increase labour supply or work effort as it will raise the after-tax reward of labour.
  • It is the money held for transactions motive which is a function of income.
  • This, in turn, results in an increase within the real disposable income of the people which raises consumption, output and employment.
  • They increase real output and shift the AS curve to the right as AS1.

Fiscal stimulus, that is, reducing taxes or increasing government expenditures , will also enhance output but, in contrast to financial stimulus , will increase the interest rate. That is as a result of it really works by shifting the IS curve upward rather than shifting the LM curve. Of course, if T increases, the IS curve will shift left, decreasing rates of interest but additionally mixture output. The standard macroeconomic argument underlying the interest rate rise is as follows. At the old equilibrium rate of interest, there is excess demand for money, given the fall in money supply. This leads the financial institutions, including commercial banks, to sell government bonds, lowering bond prices pB and raising i.

Thus, lower marginal tax rates on business profits will encourage saving and investment and step up capital accumulation. With more capital per worker, labour productivity will rise which will tend to reduce unit labour cost and lower the rate of inflation. A reduction in GNP implies a rise in unemployment rate and occur­rence of recession.

The greater the responsiveness of the demand for money to income, as measured by k, and the lower the responsiveness of the demand for money to the interest rate, as measured by h. Y, has a larger effect on the interest rate, r, the larger is k, and the smaller is h, If the demand for money is fairly inelastic, so that h is close to zero, the LM curve is nearly vertical. If the demand for money is fairly elastic (i.e., very is-lm model explained sensitive to the interest rate), so that h has a high value, then the LM curve is almost horizontal. In that case, a small change in the interest rate must be accompanied by a large change in the level of income in order to maintain money market equilibrium. Thus supply-side economists advocate reduction -in tax rates in order to increase the incentives to work, save and invest and to get more tax revenue by the govt.

The IS is negatively sloped because an increase in the interest rate reduces planned in­vestment spending and therefore reduces aggre­gate demand, thereby lowering the equilibrium level of income. When the LM curve is vertical monetary policy has a maximal effect on the level of income, and fiscal policy has no effect on income. A LM curve is drawn by keeping the stock or money provide mounted. Therefore, when the money supply will increase, given the money demand operate, it will decrease the rate of curiosity on the given degree of revenue. Winter crops such as wheat, mustard, chickpeas are due for sowing in a fortnight. Wheat prices were already up due to low stocks and anticipated shortfall in 2015–16 output and have firmed up further as demonetisation fallout pushes traders to build more inventories.

The IS-LM Curve Model (Explained With Diagram)

Accordingly, money market equilibrium implies that an increase in the interest rate is accom­panied by an increase in the level of income. A rise in planned investment spending unrelated to the interest rate shifts the aggregate demand function upward (Fig. b). This phenomenon is also observed with an autonomous rise in net exports unrelated to the interest rate.

On the other hand, an expanding economy causes interest rates to rise. Where the two curves meet, the forces are balanced and the economy is in equilibrium. Where NX stands for net exports , so how much more foreign countries demand from us than we demand from them. C is aggregate consumer spending , I is planned investments, and G is government spending. The IS-LM model finds the values of GDP and the interedst rate which simultaneously clear the goods and money markets. Where Gfix represents the fixed component of government spending, while g1 and g2 measure changes in public spending proportional to variations in income and consumption, respectively.

IS (funding–saving) curve

This implies that rate of interest varies directly with income. We measure income on the X-axis and plot the income level like the various interest rates determined at those income levels through money market equilibrium by the equality of demand for and therefore the supply of money in Fig. We may now discuss the joint equilibrium of both markets in order to see how output and interest rates are determined simultaneously. For simultaneous equilibrium, interest rates and income levels have to be such that both the goods market and the money market are in equilibrium. 38.9 shows that the interest rate and the level of output are determined by the interaction of the money and commodity markets. Interest rates and income levels are such that the public holds the existing quantity of money, and planned spending equals output .

Increase in investment leads to an increase within the economy’s capital stock, to increase in productivity, to larger output, low inflation, high level of employment and high rate of growth of the economy. Thus supply-side tax cuts by raising work, effort, saving and investment, increase the supplies of labour and capital and shift the aggregate supply curve to the right. Where AS is that the aggregate supply curve and AD is that the given demand curve. A reduction in personal tax rates increases the incentive of people to work and save more. High savings reduce short-term interest rates and lead to increased investment and thus to an increase within the economy’s capital stock. Reduction in marginal tax rates by improving the work effort of the people also increases their productive capacity and therefore the level of output and employment within the economy.

The arrival of ₹2,000 notes and the delay in issuing new notes of different denominations too are constituting an impediment to transactions. Retail trade, and through backward linkages, wholesale trade as well, lose strength as a result of this ease of transaction effect. In particular, agricultural production, harvesting, etc, are affected.
