Q

Consumption factor- cost of credit

A

Interest rates represent the price of borrowed money (cost of borrowing). Low interest rates have a positive effect on household spending for two reasons:
- interest payments represent a smaller slice of disposable income when interest rates are low
- the opportunity cost of consumption falls
Households are faced with two choices- spend or save their income. Saving is less attractive when interest rates are low, because holding surplus funds in interest-bearing deposits offer a larger rate of return

Q

Consumption factor- government economic policy

A

RBA administers monetary policy using ‘cash rate’. If he cash rate rises, higher interest rates flow through other financial markets. Meaning households have less spending power

The commonwealth government is responsible for fiscal policy- using the government spending and taxing power to influence household spending decisions

17
Q

List factors influencing investment expenditure

A
Perceived risk 
Rate of interest 
Profitability 
Business expectations 
Government policies
18
Q

Investment factor- perceived risk

A

Investment decisions concern the future- involving risk.
Investment rises and falls according to the perceived risk which the future entails. Many factors influence risk- political decisions, international events and changes in consumer sentiment

19
Q

Investment factor- rate of interest

A

Interest rates and the level of investment expenditure are negatively related
Interest rates represent the price of borrowed money so when rates rise, so do the repayments for capital items purchased with borrowed funds
Interest rates represent the opportunity cost of money. Firms have the choice of using retained profits for new investment or some alternative purpose. The opportunity cost of investment increases when interest rates are high

20
Q

Difference between nominal and real rate of interest

A

Nominal: current price of borrowed money
Real: takes the rate if inflation into account

21
Q

Investment factor- profitability

A

Many firms retain a portion of their profits for expansion- build new premises or buy new equipment
When economic conditions are challenging and profits low, firms may tend to run down capital equipment over a long period of time

22
Q

Investment factor- business expectations

A

What businesses think about the current level of economic activity and forecasts for the future. Formed as a result of current economic events
A downturn in the level of business confidence could result in a reduction in planned investment

23
Q

Investment factor- government policies

A

Fiscal and monetary policies affect investment decisions because they affect cost and expected returns
Taxing the earnings of an industry can change the risk/reward relationship in that sector
Tax incentives may attract funds to an industry. The record of the government in achieving key macroeconomic objectives also helps to foster a positive environment and encourage business confidence

24
Q

Factors influencing government expenditure

A
  • discretionary changes in according with government policy objectives eg. Social policies, health and education
  • automatic changes due to the business cycle
  • can be used to stabilise macroeconomic fluctuations
  • economic factors are not considered central to government consumption and investment decisions
25
Q

List factors affecting net exports

A
Level of domestic and overseas economic activity
Exchange rate
Movements in the terms of trade 
Presence of tariffs, quotas
Currency
26
Q

Net exports factor- level of domestic and overseas economic activity

A

Overseas demand for Australian commodity exports fluctuates according to regional and world economic conditions
Domestic levels of economic activity influence Australians’ propensity to import
Aus imports are relatively elastic with respect to GDP

27
Q

Net exports factor- exchange rate

A

When AUD rises in value, domestic residents can buy more units of other currencies and overseas residents can buy less units of the Australian currency
Australian exports become less competitive in overseas markets. Buyers of imports find they are cheaper and thus makes them more competitive against domestically produced items
Appreciation of the currency will therefore have a contractionary effect on AE, decreasing net exports

If AUD depreciates against other currencies the price of Aus exports falls for overseas buyers, but import prices increase
This has an expansionary effect on the economy and net exports will increase

28
Q

Net exports factor- movements in the terms of trade

A

A rise in Aus TOT tends to increase Aus net exports and has an expansionary effect on the economy

A fall in the TOT sees the prices received for exports fall relative to the prices paid for imports, in which case exports receipts are likely to fall
