The generally accepted definition of Inflation is the rate at which the general
level of prices for goods and services rises over time, leading to a decrease in the purchasing power of
money.
If inflation is 5%, something that costs $100 today will cost $105 a year from now
(generally speaking). In reality things increase by different amounts, inflation is measured using price
indices like the Consumer Price Index (CPI). The Consumer Price Index (CPI) is a
measure of the average change over time in the prices paid by consumers for a representative basket of
consumer goods and services. The CPI measures inflation as experienced by consumers in their day-to-day
living expenses.
A better way to think of inflation is the decreasing value of cash. Rather than
the cost of things going up, you should think of inflation as the value of cash going down.
Alan Greenspan (born March 6, 1926) is an American economist who served as the
chairman of the Federal Reserve from 1987 to 2006. During his tenure Federal policymakers privately
agreed on a 2% inflation target, but it wasn't publicly disclosed at Greenspan's insistence.
The 2% target is seen as a balance between the benefits of price stability and the risk of deflation.
Governments try to control inflation through the use of interest rate increases. Increasing
interest rates encourages saving and discourages spending.
The general opinion regarding
inflation is that a little inflation, especially if it's low, stable, and predictable, is a sign of
a healthy economy. This is because people want to see the value of their investments and assets
increase, and the value of their loans decrease. This only works in your favour if you have assets
and loans....
For this example, you borrow $100,000 from a bank at 5% fixed and 25 years and
bought a house. At the point you buy the house you earn $36,000 per year and your mortgage repayments
are $585 per month.
In this example I am going to apply the same rate of inflation to both the
value of the house and the wage increase.
This looks good, and shows the miracle of compound interest. My house has
increased in value by 20%, my wages have also increased by 20% and my mortgage repayments have stayed
the same.
Also from the lenders point of view he has done well too, he has received a 5% return
on his money, which is more than inflation by 2%.
This is an ideal situation everyone has
won.
This is more interesting. My house has tripled in value, my wages have also tripled
and my mortgage repayments have stayed the same.
However the lender has lost money, as the rate
of inflation has outstripped the interest rate by 15%.
So now you have a situation where the
lender does not want to lend money again because he lost out. This is not good as if I can't borrow
money I can't buy the house.
It's only winning if we are all winning (winning by
different rates is fine 🙂)
Inflation is difficult to control. Inflation generally occurs when demand for goods
and/or services out strips supply. The wholesale prices of goods increase, which then causes an increase
in price of retail goods which then drives up the need for increased wages which also drives up the cost
for services. While everything is adjusting it's a painful period for a lot of people. If your
supermarket bill has increased significantly and your wages have not, that's not going to be a
pleasant experience.
Governments can exercise a limited level of control over inflation,
typically they can set interest rates of their central bank and/or print more money (quantitive easing).
This is why governments favour a low (2%) and controllable rate of inflation. Everyone wins and the
government looks as though they are managing the economy successfully.
On the 18th of April 1980, Rhodesia managed to swap a white racist government for a
black racist government and renamed itself Zimbabwe. A series of mistakes called the Economic Structural
Adjustment Programme (ESAP) led to a 45% decrease in food production, an 80% increase in unemployment
and an decrease in the life expectancy of the population. Demand for food, goods and services
outstripped supply and with the government unwilling to change anything, led to Hyperinflation.
The picture is of a one hundred trillion dollar note being swapped for two coconuts.
