Inflation, Types, Causes

Economists believe that very high rates of inflation and hyperinflation are harmful, and are caused by an excessive growth of the money supply. Views on which factors determine low to moderate rates of inflation are more varied. Low or moderate inflation may be attributed to fluctuations in real demand for goods and services, or changes in available supplies such as during scarcities. However, the consensus view is that a long-sustained period of inflation is caused by money supply growing faster than the rate of economic growth.

Inflation affects economies in various positive and negative ways. The negative effects of inflation include an increase in the opportunity cost of holding money, uncertainty over future inflation which may discourage investment and savings, and if inflation were rapid enough, shortages of goods as consumers begin hoarding out of concern that prices will increase in the future. Positive effects include reducing unemployment due to nominal wage rigidity, allowing the central bank more leeway in carrying out monetary policy, encouraging loans and investment instead of money hoarding, and avoiding the inefficiencies associated with deflation.

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:

On the Basis of Causes:

• Currency inflation:

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

• 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.

• 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.

• 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.”

Keynesians hold a different argu­ment. They argue that there can be an autonomous increase in aggregate de­mand or spending, such as a rise in con­sumption demand or investment or government spending or a tax cut or a net increase in exports (i.e., C + I + G + X – M) with no increase in money sup­ply. This would prompt upward adjust­ment in price. Thus, DPI is caused by monetary factors (classical adjustment) and non-monetary factors (Keynesian argument).

• 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.

On the Basis of Speed or Intensity:

• 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.

• 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.

• 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”.

• 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.

Main Causes of inflation

• Inflation can arise from internal and external events
• Some inflationary pressures direct from the domestic economy, for example the decisions of utility businesses providing electricity or gas or water on their tariffs for the year ahead, or the pricing strategies of the food retailers based on the strength of demand and competitive pressure in their markets.
• A rise in the rate of VAT would also be a cause of increased domestic inflation in the short term because it increases a firm’s production costs.
• Inflation can also come from external sources, for example a sustained rise in the price of crude oil or other imported commodities, foodstuffs and beverages.
• Fluctuations in the exchange rate can also affect inflation, for example a fall in the value of the pound against other currencies might cause higher import prices for items such as foodstuffs from Western Europe or technology supplies from the United States, which feeds through directly or indirectly into the consumer price index.
