Inflation

Elementary Idea of Inflation

Inflation is often defined in terms of its supposed causes. Inflation exists when money supply exceeds available goods and services. Or inflation is attributed to budget deficit financing. A deficit budget may be financed by the additional money creation. But the situation of monetary expansion or budget deficit may not cause price level to rise.

Inflation may be defined as ‘a sustained upward trend in the general level of prices’ and not the price of only one or two goods. G. Ackley defined inflation as ‘a persistent and appreciable rise in the general level or aver­age of prices’. In other words, inflation is a state of rising prices, but not high prices.

It is not high prices but rising price level that con­stitute inflation. It constitutes, thus, an over­all increase in price level. It can, thus, be viewed as the devaluing of the worth of money. In other words, inflation reduces the purchasing power of money. A unit of money now buys less. Inflation can also be seen as a recurring phenomenon.

While measuring inflation, we take into ac­count a large number of goods and services used by the people of a country and then cal­culate average increase in the prices of those goods and services over a period of time. A small rise in prices or a sudden rise in prices is not inflation since they may reflect the short term workings of the market

It is to be pointed out here that inflation is a state of disequilib­rium when there occurs a sustained rise in price level. It is inflation if the prices of most goods go up. Such rate of increases in prices may be both slow and rapid. However, it is difficult to detect whether there is an upward trend in prices and whether this trend is sus­tained. That is why inflation is difficult to define in an unambiguous sense.

Types of Inflation

As the nature of inflation is not uniform in an economy for all the time, it is wise to distin­guish between different types of inflation. Such analysis is useful to study the distribu­tional and other effects of inflation as well as to recommend anti-inflationary policies. Infla­tion may be caused by a variety of factors. Its intensity or pace may be different at different times. It may also be classified in accordance with the reactions of the government toward inflation.

Thus, one may observe different types of inflation in the contemporary society:

1. On the Basis of Causes

(i) Currency inflation

This type of infla­tion is caused by the printing of cur­rency notes.

(ii) Credit inflation

Being profit-making institutions, commercial banks sanction more loans and advances to the public than what the economy needs. Such credit expansion leads to a rise in price level.

(iii) Deficit-induced inflation

The budget of the government reflects a deficit when expenditure exceeds revenue. To meet this gap, the government may ask the central bank to print additional money. Since pumping of additional money is required to meet the budget deficit, any price rise may the be called the deficit-induced inflation.

(iv) Demand-pull inflation

An increase in aggregate demand over the available output leads to a rise in the price level. Such inflation is called demand-pull in­flation (henceforth DPI). But why does aggregate demand rise? Classical economists attribute this rise in aggre­gate demand to money supply. If the supply of money in an economy ex­ceeds the available goods and services, DPI appears. It has been described by Coulborn as a situation of “too much money chasing too few goods.”

(v) Cost-push inflation

Inflation in an economy may arise from the overall increase in the cost of production. This type of inflation is known as cost-push inflation (henceforth CPI). Cost of pro­duction may rise due to an increase in the prices of raw materials, wages, etc. Often trade unions are blamed for wage rise since wage rate is not completely market-determinded. Higher wage means high cost of production. Prices of commodities are thereby increased.

A wage-price spiral comes into opera­tion. But, at the same time, firms are to be blamed also for the price rise since they simply raise prices to expand their profit margins. Thus, we have two im­portant variants of CPI wage-push in­flation and profit-push inflation.

2. On the Basis of Speed or Intensity

(i) Creeping or Mild Inflation

If the speed of upward thrust in prices is slow but small then we have creeping inflation. What speed of annual price rise is a creeping one has not been stated by the economists. To some, a creeping or mild inflation is one when annual price rise varies between 2 p.c(%). and 3 p.c(%). If a rate of price rise is kept at this level, it is con­sidered to be helpful for economic development. Others argue that if annual price rise goes slightly beyond 3 p.c. mark, still then it is considered to be of no danger.

(ii) Walking Inflation

If the rate of annual price increase lies between 3 p.c. and 4 p.c., then we have a situation of walking inflation. When mild inflation is allowed to fan out, walking inflation appears. These two types of inflation may be described as ‘moderate inflation’.

Often, one-digit inflation rate is called ‘moder­ate inflation’ which is not only predict­able, but also keep people’s faith on the monetary system of the country. Peoples’ confidence get lost once moderately maintained rate of inflation goes out of control and the economy is then caught with the galloping inflation.

(iii) Galloping and Hyperinflation

Walking inflation may be converted into running inflation. Running inflation is danger­ous. If it is not controlled, it may ulti­mately be converted to galloping or hyperinflation. It is an extreme form of inflation when an economy gets shattered. ”Inflation in the double or triple digit range of 20, 100 or 200 p.c. a year is labelled “galloping inflation”.

(iv) Government’s Reaction to Inflation

In­flationary situation may be open or suppressed. Because of anti-infla­tionary policies pursued by the govern­ment, inflation may not be an embar­rassing one. For instance, increase in income leads to an increase in con­sumption spending which pulls the price level up.

If the consumption spending is countered by the govern­ment via price control and rationing device, the inflationary situation may be called a suppressed one. Once the government curbs are lifted, the sup­pressed inflation becomes open infla­tion. Open inflation may then result in hyperinflation.

Causes of Inflation

Inflation is mainly caused by excess demand/ or decline in aggregate supply or output. Former leads to a rightward shift of the aggregate demand curve while the latter causes aggregate supply curve to shift left­ward. Former is called demand-pull inflation (DPI), and the latter is called cost-push infla­tion (CPI). Before describing the factors, that lead to a rise in aggregate demand and a de­cline in aggregate supply, we like to explain “demand-pull” and “cost-push” theories of inflation.

(i) Demand-Pull Inflation Theory

There are two theoretical approaches to the DPI—one is classical and other is the Keynesian.

According to classical economists or mon­etarists, inflation is caused by an increase in money supply which leads to a rightward shift in negative sloping aggregate demand curve. Given a situation of full employment, classi­cists maintained that a change in money supply brings about an equiproportionate change in price level.

That is why monetarists argue that inflation is always and everywhere a monetary phenomenon. Keynesians do not find any link between money supply and price level causing an upward shift in aggregate demand.

According to Keynesians, aggregate demand may rise due to a rise in consumer demand or investment demand or govern­ment expenditure or net exports or the com­bination of these four components of aggreate demand. Given full employment, such in­crease in aggregate demand leads to an up­ward pressure in prices. Such a situation is called DPI. This can be explained graphically.

Just like the price of a commodity, the level of prices is determined by the interaction of aggregate demand and aggregate supply. In Fig. aggregate demand curve is negative sloping while aggregate supply curve before the full employment stage is positive sloping and becomes vertical after the full employ­ment stage is reached. AD1 is the initial aggregate demand curve that intersects the aggregate supply curve AS at point E1.

The price level, thus, determined is OP1. As ag­gregate demand curve shifts to AD2, price level rises to OP2. Thus, an increase in aggre­gate demand at the full employment stage leads to an increase in price level only, rather than the level of output. However, how much price level will rise following an increase in aggregate demand depends on the slope of the AS curve.

(ii) Causes of Demand-Pull Inflation

DPI originates in the monetary sector. Mon­etarists’ argument that “only money matters” is based on the assumption that at or near full employment excessive money supply will in­crease aggregate demand and will, thus, cause inflation.

An increase in nominal money supply shifts aggregate demand curve rightward. This enables people to hold excess cash bal­ances. Spending of excess cash balances by them causes price level to rise. Price level will continue to rise until aggregate demand equals aggregate supply.

Keynesians argue that inflation originates in the non-monetary sector or the real sector. Aggregate demand may rise if there is an increase in consumption expenditure following a tax cut. There may be an autonomous increase in business investment or government expendi­ture. Government expenditure is inflationary if the needed money is procured by the gov­ernment by printing additional money.

In brief, increase in aggregate demand i.e., in­crease in (C + I + G + X – M) causes price level to rise. However, aggregate demand may rise following an increase in money supply gen­erated by the printing of additional money (classical argument) which drives prices up­ward. Thus, money plays a vital role. That is why Milton Friedman argues that inflation is always and everywhere a monetary phenom­enon.

There are other reasons that may push ag­gregate demand and, hence, price level up­wards. For instance, growth of population stimulates aggregate demand. Higher export earnings increase the purchasing power of the exporting countries. Additional purchasing power means additional aggregate demand. Purchasing power and, hence, aggregate de­mand may also go up if government repays public debt.

Again, there is a tendency on the part of the holders of black money to spend more on conspicuous consumption goods. Such tendency fuels inflationary fire. Thus, DPI is caused by a variety of factors.

(iii) Cost-Push Inflation Theory

In addition to aggregate demand, aggregate supply also generates inflationary process. As inflation is caused by a leftward shift of the aggregate supply, we call it CPI. CPI is usu­ally associated with non-monetary factors. CPI arises due to the increase in cost of produc­tion. Cost of production may rise due to a rise in cost of raw materials or increase in wages.

However, wage increase may lead to an in­crease in productivity of workers. If this hap­pens, then the AS curve will shift to the right- ward not leftward—direction. We assume here that productivity does not change in spite of an increase in wages.

Such increases in costs are passed on to consumers by firms by rais­ing the prices of the products. Rising wages lead to rising costs. Rising costs lead to rising prices. And, rising prices again prompt trade unions to demand higher wages. Thus, an inflationary wage-price spiral starts. This causes aggregate supply curve to shift leftward.

This can be demonstrated graphically where AS1 is the initial aggregate supply curve. Below the full employment stage this AS curve is positive sloping and at full em­ployment stage it becomes perfectly inelastic.

Intersection point (E1) of AD1 and AS1 curves determine the price level (OP1). Now there is a leftward shift of aggregate supply curve to AS2. With no change in aggregate demand, this causes price level to rise to OP2 and output to fall to OY2. With the reduction in output, employment in the economy de­clines or unemployment rises. Further shift in AS curve to AS3 results in a higher price level (OP3) and a lower volume of aggregate out­put (OY3). Thus, CPI may arise even below the full employment (YF) stage.

(iv) Causes of Cost-Push Inflation

It is the cost factors that pull the prices up­ward. One of the important causes of price rise is the rise in price of raw materials. For in­stance, by an administrative order the govern­ment may hike the price of petrol or diesel or freight rate. Firms buy these inputs now at a higher price. This leads to an upward pres­sure on cost of production.

Not only this, CPI is often imported from outside the economy. Increase in the price of petrol by OPEC com­pels the government to increase the price of petrol and diesel. These two important raw materials are needed by every sector, espe­cially the transport sector. As a result, trans­port costs go up resulting in higher general price level.

Again, CPI may be induced by wage-push inflation or profit-push inflation. Trade unions demand higher money wages as a compen­sation against inflationary price rise. If in­crease in money wages exceed labour produc­tivity, aggregate supply will shift upward and leftward. Firms often exercise power by push­ing prices up independently of consumer de­mand to expand their profit margins.

Fiscal policy changes, such as increase in tax rates also leads to an upward pressure in cost of production. For instance, an overall in­crease in excise tax of mass consumption goods is definitely inflationary. That is why govern­ment is then accused of causing inflation.

Finally, production setbacks may result in decreases in output. Natural disaster, gradual exhaustion of natural resources, work stop­pages, electric power cuts, etc., may cause ag­gregate output to decline. In the midst of this output reduction, artificial scarcity of any goods created by traders and hoarders just simply ignite the situation.

Inefficiency, corruption, mismanagement of the economy may also be the other reasons. Thus, inflation is caused by the interplay of various factors. A particular factor cannot be held responsible for any inflationary price rise.

Inflation Meaning and Theories and Control Measures

In economics, inflation means rise in the general level of prices of goods and services over a period of time in an economy. Inflation may affect the economy either in positive way or negative way.

Causes of Inflation

The causes of inflation are as follows −

• Inflation may occur sometimes due to excessive bank credit or currency depreciation.
• It may be caused due to increase in demand in relation to supply of all types goods and services due to a rapid increase in population.
• Inflation also may be also be caused by a change in the value of production costs of goods.
• Export boom inflation also comes into existence when a considerable increase in exports may cause a shortage in the home country.

Inflation is also caused by decrease in supplies, consumer confidence, and corporate decisions to charge more.

Measures to Control Inflation

There are many ways of controlling inflation in an economy −

Monetary Measure

The most important method of controlling inflation is monetary policy of the Central Bank. Most central banks use high interest rates as a way to fight inflation. Following are the monetary measures used to control inflation −

• Bank Rate Policy− Bank rate policy is the most common tool against inflation. The increase in bank rate increases the cost of borrowings which reduces commercial banks borrowing from the central bank.
• Cash Reserve Ratio− To control inflation, the central bank needs to raise CRR which helps in reducing the lending capacity of the commercial banks.
• Open Market Operations− Open market operations mean the sale and purchase of government securities and bonds by the central bank.

Fiscal Policy

Fiscal measures are another important set of measures to control inflation which include taxation, public borrowings, and government expenses. Some of the fiscal measures to control inflation are as follows −

• Increase in savings
• Increase in taxes
• Surplus budgets

Wage and Price Controls

Wage and price controls help in controlling wages as the price increases. Price control and wage control is a short term measure but is successful; since in long run, it controls inflation along with rationing.

Impact of Inflation on Managerial Decision Making

Inflation is of course the all too familiar problem of too much money (demand) chasing too few goods (supply), with the upshot of prices and expectations everywhere tending to rise higher and higher.

The Role of a Manager

In these circumstance, a business manager has to take appropriate decisions and measures based on macro economic uncertainties like inflation and the occasional recession.

A true test of a business manager lies in delivering profitability ie., the extent to which he increases revenues and also reduces costs even during economic uncertainties.

In the current scenario, they are supposed to get faster solutions to the problems of coping with soaring prices (for example) by understanding the process of how inflation distorts the traditional functions of money along with recommendations.

The Effect of Management

The bottom-line impact is that, Customers / clients reward efficient management with profits and penalize inefficient management with losses. Hence, it is advisable to be well prepared to tackle these areas.
