Inflation Flashcards
Inflation
A persistent rise in the general level of prices, or alternatively a persistent falls in the value of money.
Deflation
A persistent downward movement in the general price level overtime for an aggregate of goods and services.
Types of inflation
Creeping Galloping/hyperinflation Trotting Open Suppressed Stagflation
Creeping inflation
Occurs when there is a sustained mild rise in the price level per year i.e. between one and six per cent.
Galloping inflation
It develops at a rapid pace, perhaps only for a brief period of time.
Such form of inflation is dangerous for the economy as it mostly affects the middle and low-income classes of population.
Importantly, the galloping inflation can precipitate an economic depression.
Trotting inflation
Occurs when prices increase at intermediate rates (between the two types above)
Open inflation
Inflation is open when “markets for goods or factors of production are allowed to function freely, setting prices of goods and factors without normal interference by the authorities.” Thus open inflation is the result of the uninterrupted operation of the market mechanism.
Suppressed inflation
It describes a situation in which, at existing wages and prices, the aggregate demands for current output and labor services exceed the corresponding aggregate supplies. In suppressed inflation, purchases of goods and labor services are rationed.
Stagflation inflation
A situation in which the inflation rate is high, the economic growth rate slows, and unemployment remains steadily high.
It presents a dilemma for economic policy, since actions intended to lower inflation may exacerbate unemployment.
Measurements of inflation
The Consumer Price Index
The Producer Price Index
GDP deflator index
Consumer Price Index (CPI) - MAIN
Measures the relative changes in the prices of a specified set of market basket of consumer goods, which are bought by a typical urban household regularly.
The producer price index (PPI)
Measures relative changes in the prices of raw materials, intermediate and finished goods i.e. at all stages of the productive process rather than at the stage of the ultimate user.
GDP deflator index
Measures the level of prices of all new, domestically produced, final goods and services in an economy
Steps followed in Calculating Consumer Index
- Determine which prices are the most important to a typical consumer.
- Find the prices of each of the goods and services in the basket at each point in time
- Use the data in prices to calculate the cost of the basket of goods and services at different times.
- Designate one year as the base year- the benchmark against which other years are compared.
- Use the CPI to calculate the inflation rate which is the percentage change in the price index from the preceding period
CPI =
CPI = price of basket in current year/price of basket in base year *100
Inflation in Yr 2 = CPI in Yr 2 - CPI in Yr 1/CPI in Yr 1 *100
