Discuss whether fiscal policy is the most effective way for Singapore to sustain a successful economy, with low unemployment, low inflation, and economic growth. [25]


This paper discusses if fiscal policy is the most effective way for Singapore to sustain a successful economy, where the idea of a “successful economy” is based on attaining the macroeconomic goals of generally low unemployment, low inflation, and economic growth. The means of attaining each of these desirable macroeconomic objectives may sometimes be at odds with other macroeconomic goals because of trade-offs. The most effective way for Singapore to sustain a successful economy is not to depend on one single macroeconomic policy; in particular, due to Singapore’s small and open economy, fiscal policy would go only a little way to help Singapore attain her macroeconomic goals, and a combination of exchange rate policy and supply-side policies would work more effectively instead.

Fiscal Policy Can Be Effective

First and foremost, it can be argued that fiscal policy could theoretically achieve the macroeconomic goals of low unemployment, low inflation, and economic growth. First, low unemployment can be achieved through the use of expansionary fiscal policy. What does expansionary fiscal policy mean? It  means increasing government spending (G) or lowering taxes (T), in times of high unemployment or recession. The discretionary expenditure by the government, for instance on the military or on education, would raise aggregate demand (AD) and drive up employment, due to the multiplier effect, thus resulting in a higher level of employment. AD shifts to the right and causes unemployment to fall. What is unemployment? Unemployment is defined as the situation in which people who are willing and able to work are unable to find employment. Secondly, likewise, stable actual economic growth can attained the same way, because expansionary fiscal policy can ensure that growth is maintained during recessions. Actual growth can be thought of as an increase in real national output. These implications are reflected in the diagram below.

Likewise, fiscal policy can be used to reduce inflation by contracting AD in times of high inflation in order to reduce inflationary pressures and control prices. This is the reverse of expansionary fiscal policy; contractionary fiscal policy can reduce AD in times of inflation. Inflation is defined as a persistent and inordinate increase in the general price level, and if it is demand-pull, contractionary fiscal policy reduces AD accordingly.

Limitations of Fiscal Policy

On the other hand, the way fiscal policy works in reality is different from theory because policymakers may not know exactly where the full employment level is in reality, and time lags, recognition lags, and implementation lags are all real. All the theoretical effects of fiscal policy also assume that the economy has a sufficiently large multiplier for the injections by the government to make large impacts on national income and employment. It also presupposes that the government’s budget does not suffer from massive deficits, and that fiscal policy would not result in the “crowding out effect”, when the government drives up interest rates, negatively affecting the private sector, when it attempts to finance policies through borrowing.

However, more importantly, while the Singapore government’s finances is such that it can potentially deliver a fiscal stimulus without financial or political problems, the fact that Singapore’s national multiplier is small implies that this would not have a great impact on growth or employment. The high level of imports and high proportion of savings in Singapore means that the multiplier effect would be small. Furthermore, fiscal policy seems most effective in reducing cyclical unemployment, associated with falling AD during a recession, and does not go a long way in relieving structural or frictional unemployment; as for inflation fiscal policy helps reduce demand-pull inflation and does not go a long way in alleviating cost-push inflation. Even if fiscal policy could generate employment, it is only in the short run, and unemployment will eventually return if it was actually due to structural unemployment, the mismatch of skills and knowledge in an economy due to structural changes in the methods of production, and hence such reductions in unemployment and the concomitant growth would not be sustainable.

Exchange Rate Policy

In order to sustain a successful economy, arguably a combination of fiscal, monetary and supply-side policies is required instead. In particular, monetary policy – in Singapore’s context, an exchange rate policy – would be able to affect AD during short-term economic fluctuations. It should be noted that interest rates-based monetary policy cannot be applied in Singapore as a result of Singapore’s vulnerability to short-term capital flows and thus an exchange rate policy has to be adopted in Singapore. As Singapore is dependent on imports, low inflation can be sustained instead through a gradual appreciation of the currency, because the imports would look relatively cheap vis-à-vis other countries. However, it should be noted also that this would affect exports negatively, on the flip-side.

On the other hand, depreciation can be used to increase AD, by raising demand for Singapore’s exports, since short-term depreciations of the Singapore dollar could help to raise competitiveness of Singapore’s exports and thus drive growth and generate employment. However, it should again be noted that this would affect inflation, on the flip-side. Hence, trade-offs are inevitable, although exchange rate policy is clearly a viable alternative.

Supply-Side Policies

As for long-term economic growth and stability, supply-side policies are necessary to sustain potential growth. Education and retraining of workers has to be implemented in order to maintain flexibility of labour and allow Singapore to cope with structural changes.

Furthermore, in terms of reducing unemployment, job fairs and placement or matching agencies could also help reduce frictional unemployment. Low domestic inflation can be maintained in the long run through continuous improvements in productivity and the enhancement of cost-competitiveness. The productive capacity of the economy must grow continuously in order for increases in AD to translate into sustained, non-inflationary, real economic growth in Singapore's national output; this increase in LRAS can be encouraged through fiscal spending that has supply-side effects such as investments in infrastructure and education, which would both affect AD and LRAS, leading to economic growth both actual and potential.


In conclusion, the application of fiscal policy is not an effective way for Singapore to sustain a successful economy that achieves its macroeconomic aims, thanks primarily to the small and open nature of the Singapore economy that gives rise to a small multiplier resulting from the high level of leakages due to high savings from CPF and high import contents in inputs. This reduces the impact that fiscal policy can have on the economy because the famous Keynesian multiplier effect is mitigated. The current managed float exchange rate policy that Singapore adopts is more significant in achieving short-term demand-management objectives. In the long-run, the government would sustain a successful economy through a combination of both demand-management and supply-side policies that enhance the long-term productivity and productive capacity of the economy, thus providing potential growth, whilst driving AD through actual growth, which reduces unemployment and spearheads economic development. Hence, fiscal policy is clearly not the most effective way – an economic policy package is better.
