inflation and deflation

What is Inflation or What is the meaning of Inflation? 
In economics inflation means, a rise in general level of prices of goods and services in a economy over a period of time.   When the general price level rises, each unit of currency buys fewer goods and services.  Thus, inflation results in loss of value of money.   Another popular way of looking at inflation is "too much money chasing too few goods".   The last definition attributes the cause of inflation to monetary growth relative to the output / availability of goods and services in the economy.

In case the price of say only one commodity rise sharply but prices of other commodities fall, it will not be termed as inflation.  Similarly, in case due to rumors if the price of a commodity rise during the day itself, it will not be termed as inflation.

What are different types of inflation?
Broadly speaking inflation is divided into two categories i.e.

(a) DEMAND - PULL INFLATION:   In this type of inflation prices increase results  from an excess of demand over supply for the economy as a whole. Demand inflation occurs when supply cannot expand any more to meet demand; that is, when critical production factors are being fully utilized, also called Demand inflation.

(b) COST - PUSH INFLATION:   This type of inflation occurs when general price levels rise owing to rising input costs. In general, there are three factors that could contribute to Cost-Push inflation: rising wages, increases in corporate taxes, and imported inflation. [imported raw or partly-finished goods may become  expensive due to rise in international costs or as a result of  depreciation of local currency ]


What is Deflation ?
Deflation is the opposite of inflation.   Deflation refers to  situation, where there is decline in general price levels.   Thus, deflation occurs when the inflation rate falls below 0% (or it is negative inflation rate).   Deflation increases the real value of money and allows one to buy more goods with the same amount of money over time.   Deflation can occur owing to reduction in the supply of money or credit.   Deflation can also occur due to  direct contractions in spending, either in the form of a reduction in government spending, personal spending or investment spending. Deflation has often had the side effect of increasing unemployment in an economy, since the process often leads to a lower level of demand in the economy.
