Discuss the likely causes of inflation in Singapore . [15]
Inflation occurs when there is a rise in the general
price level of goods and services. Inflation becomes a problem when the rise in
general price level is sustained and inordinate. With inflation, a given amount
of nominal income buys less goods and services than before. Inflation caused by
demand-side factors is known as Demand-pull inflation while inflation caused by
supply-side factors is known as Cost-push inflation.
Firstly, demand-pull inflation occurs when Aggregate
Demand (AD) rises as the economy approaches full employment. AD will rise if
there is a decrease in interest rate as when there is a decrease in interest
rate, it becomes cheaper and easier for people to consume and invest causing
consumption and investment to increase.
Secondly, AD will also rise when there is a decrease in
personal income tax as people will tend to have more disposable income and this
increases their purchasing power and will cause consumption to increase. Since AD comprises C + I + G + (X-M),
which are consumer spending, investment spending, government spending, and net
exports, a rise in consumption and investment spending will cause AD to
rise from AD to AD2.
Lastly, Factors like increase in government spending and
net exports and will also cause AD to rise, leading to demand-pull inflation as
general price level increases from P1 to P2.
Cost-push inflation
occurs when Aggregate Supply (AS) rises due to economy-wide rises in production
costs, for reasons not associated with rising domestic demand. As labour cost
is often the largest component of total cost, a sudden rise in wages can cause
significant cost-push inflation. Rising food, fuel, property prices, exchange
rates and the foreign sector are also factors that causes AS to rise from SRAS1
to SRAS2, (Figure 2) leading to cost-push inflation as general price level
increases from P1 to P2. Imported inflation can lead also lead to cost push
inflation.
With a small
domestic market and being highly export-oriented, Singapore is more dependent on
external rather than domestic demand. If the Singapore dollar were to appreciate
too quickly, her exports and hence AD would plummet and this potentially
triggers a recession.
Hence, Singapore ’s
central bank, known as the Monetary Authority of Singapore (MAS) has a primary
objective which is to promote price stability through monetary policy. In order
to effectively manage Singapore ’s
exchange rate, the central bank buys back its own currency from the foreign
exchange market which reduces money supply to raise the exchange rate.
Conversely, the central bank also sells domestic currency on the foreign
exchange market which raises money supply to lower the exchange rate.
