Active learning ideas
Monetary policy involves the management of the money supply and interest rates to achieve macroeconomic goals like price stability and sustainable growth. Students explore the transmission mechanism, through which changes in interest rates affect consumption, investment, and aggregate demand. In Singapore, the unique 'exchange rate-centered' monetary policy is a key focus, reflecting our status as a small, open economy.
Activity 01
Groups act as the MAS board. They are given a set of economic data (inflation, growth, exchange rates) and must decide whether to tighten, loosen, or maintain their policy stance, justifying their decision with an AD-AS diagram.
What drives the volatility of short-term capital flows?
Activity 02
Stations around the room represent different parts of the economy (households, firms, the housing market). Students move in groups to explain how a rise in interest rates would affect each sector, using flowcharts to show the links.
How does the macroeconomic trilemma constrain central banks?
Activity 03
Students discuss why Singapore uses the exchange rate rather than interest rates as its primary monetary tool. They share their thoughts on how this helps manage imported inflation and export competitiveness.
Why does Singapore utilize an exchange rate-centered monetary policy?
A few notes on teaching this unit
Watch Out for These Misconceptions
The central bank can perfectly control the inflation rate.
Monetary policy has significant time lags and is subject to external shocks that are beyond the central bank's control. Role-playing as central bankers helps students appreciate the uncertainty and complexity of economic management.
A lower interest rate always leads to more investment.
If business confidence is low, firms may not invest even if borrowing is cheap. Peer discussion on 'animal spirits' and the importance of expectations helps students understand the limitations of monetary policy.
