Fiscal Policy
Fiscal policy is changes in federal taxes and purchases that are intended to achieve
macroeconomic policy objectives, such as high employment, price stability, and
healthy rates of economic growth.
Fiscal policy refers to the actions of the federal government, and not state, territory,
or local governments.
Using fiscal policy to influence aggregate demand
Aggregate Demand: the total demand for goods and services within a particular market.
Expansionary fiscal policy
Increases in government purchases and/or decreases in taxes in order to increase
aggregate demand
An increase in government purchases will increase aggregate demand directly
A reduction in taxes has an indirect effect on aggregate demand through the affect
on disposable income.
The goal of expansionary fiscal policy is to increase aggregate demand by more than
what it would have increased without policy
Appropriate when the economy is in equilibrium, below full-employment, e.g. during
an economic contraction or recession
Leftward shift
Contractionary fiscal policy
Contractionary fiscal policy: decreases on government purchases and/or increases in
taxes in order to reduce aggregate demand
Appropriate when the economy is above full employment equilibrium and the
inflation rate is high.
Rightward shift
Automatic Fiscal Stabilisers
They work to stabilise the economy without the need to change policy
Examples:
Progressive personal income tax rates and transfer payments

The Limits of Using Fiscal Policy to Stabilise the Economy
There are two main problems associated with fiscal policy effectiveness
1. Timing lags
2. Crowding out
What is monetary policy?
Monetary policy: the actions taken by the Reserve Bank of Australia to manage
interest rates in the pursuit of macroeconomics
Since 1993 the RBA has focused on monetary policy on achieving price stability
Inflation targeting: conducting monetary policy so as to commit the central bank to
achieving a publicly announced level of inflation
Inflation: a general increase in prices and fall in the purchasing value of money.
The RBA's target inflation is between 2% and 3% per annum on average over the
business cycle
Bonds
Bonds are a method of raising finance available to businesses and governments
Bonds are a legal promise to repay a loan, usually including a principle amount and
regular interest payments. On issue, the agreed interest rate is called the coupon rate
and the interest payments are called the coupon payments
Supply of Money and Equilibrium
The money supply is influenced by the RBA and consists of notes and coins in
circulation plus deposits in the banking system
Does not depend on interest rates, so money supply curve is vertical with respect to
interest rates
Equilibrium interest rate occurs where monetary demand and supply curves
intersect
Monetary Policy and Open-Market Operations
An increase in the supply of money leads to a decrease in the interest rate
Equivalently, if the central bank wants to raise the interest rate, it must decrease the
supply of money
Open market operations, which take place in the 'open market' for bonds, are the
standard method central banks use to change the money stock in modern economies
Monetary Policy
RBA no longer targets the money supply to conduct monetary policy
Cash rate: the interest rate on loans in the overnight money market
The cash rate is determined by the interaction of demand for and supply funds in the
overnight money market
RBA Targets the Cash Rate
