Money and Price Level

Paper Money
• Does Paper Money have any intrinsic value?
• What is money then?
• Why is it important?
• If there was no money then we would have to barter
• For barter to work – trade is said to require the double
of coincidence of wants.
The history of money
• Mesopotamian civilization developed a large
scale economy based on “Commodity money”
• Many other cultures also developed commodity
money
• Tobacco in America, Shells in India, Spices in
Europe, Alcohol in New South Wales

of money to smuggle in.

Why is inflation Unpopular
• Higher inflation means you have to spend more?
• When viewed from the income side –
– Higher inflation means
• You get paid more
• You get more for your factors of production.
• UNLESS PRODUCTIVITY INCREASES HIGHER
WAGES MEAN HIGHER PRICES
• Who are hurt the most because of inflation
– Individuals whose incomes are fixed in nominal terms
– Pensions, EPF
Factors of Inflation
• Increase in the money supply
• Decrease in the demand for money
• Decrease in aggregate supply of goods and
services.
• Increase in aggregate demand for goods and
services.
Cost push inflation
• Basically means that prices have been pushed
up due to the increase in the 4 factors of
production.
• Higher production costs
• Companies cannot maintain profit margins
• Costs are passed on to the consumer
• Prices rise
• Rising Prices mean inflation has increased.
Demand pull inflation
• Occurs when there is an increase in aggregate
demand
• When the four sectors of the economy
increase their consumption
– Households, Government, Firms, Foreign buyers
• They bid prices up
• Increased prices = inflation.
Is inflation bad?
• Practically every economist will tell you that
– a little bit of inflation is a good thing
– a lot of inflation is a bad thing
• A little bit of inflation is like a tax on idle money. It prompts
people to get their money out of the mattress (or low
interest accounts) and put it to work on investments.
• A lot of inflation prompts people drives money out of
economy-driving investments and into inflation-proofing
investments (gold which does nothing for the economy).
• Deflation makes idle money profitable so no one, not the
Fed or economists, wants to see deflation. If deflation was
a risk today, you would see the Fed trying to fight it.
International Trade
1912 Trade Routes
The production possibilities frontier
• Australia can produce either 100 Agricultural
products or 50 electronic products

• When countries specialize world output

Free trade vs Fair Trade
• Free Trade – The flow of good and services

barriers to entry if the other country does not
have some sort of “unfair competitive”
advantage. And also provided that the other
country also reduces its trade barriers.
