Practise explaining how demand-side factors such as population, visitors and exchange rates can alter aggregate demand.
Malaysia's uncertain economic prospects
Malaysia is an emerging middle-income country. Its increasing population is an important factor in promoting future economic growth. The country, however, faces two underlying problems. First, the fertility rate, the average number of children a woman can expect to give birth to, has fallen consistently as Malaysia's economy has developed. This rate is now below the critical level where a population replaces itself. Second, Malaysia has an ageing population, with an increasing proportion of its population over 65 years of age. In 2015 the average age of Malaysia's population was 28.2 years; in 2030 it is forecast to reach 34.1 years. Malaysia's forecast total population to 2027 and its ageing population from 2017 to 2022 are shown in Figs. 1.1 and 1.2 below.

Fig. 1.1 Total population of Malaysia, 2017 to 2027
The key issue for Malaysia's government is whether it is prepared for this fundamental shift in its population. There is plenty of scope for optimism. The economy appears to have recovered from the shock of the COVID-19 pandemic. Its growth rate in 2021 and the 2022 forecast was above the government's target of 5.1%, with substantial growth in exports of electrical and electronic goods, palm oil, gas and oil supplies. Unemployment is below 4\% and the current account of the balance of payments was projected to have a record surplus in 2022.
Economists, however, fear that Malaysia's government and its people are not ready to meet the challenges of an ageing population. In a recent survey, 70% of respondents felt it was the duty of the young to take care of the elderly, but they were also concerned that the economy could not cope with the pressure on its human capital and other resources. More resources will have to be allocated to meet the needs of the elderly.
It was further argued that Malaysia needed a proper plan for dealing with this situation. According to one economist, free childcare for working parents was essential and tax incentives should be used to keep more elderly workers in employment.
Excluding net exports, assess the likely impact of the change in Malaysia's total population on aggregate demand.
Up to 3 marks for explanation/analysis of the change in Malaysia's total population would increase the level of aggregate demand.
- A larger population means more consumers, so overall spending on goods and services (consumption) increases, causing AD to rise.
- Population growth creates higher demand for housing and infrastructure, encouraging firms to invest more, which raises investment in AD.
- The government may need to spend more on healthcare, education, and other public services, increasing government expenditure, a component of AD.
- More people can lead to a bigger workforce, increasing total income in the economy and allowing households to spend more, boosting consumption.
Up to 3 marks for explanation/analysis of the change in Malaysia's total population would reduce the level of aggregate demand.
- If population growth causes unemployment to rise, many people may have lower or no income, reducing overall consumption and limiting AD growth.
- If people decide to save more due to uncertainty about the future, the increase in consumption will be smaller, so AD won't rise much.
- Increased demand from a larger population might cause prices to rise (inflation), reducing the real value of incomes and spending power.
- Government budgets may be strained by population growth, limiting its ability to increase spending, so the impact on AD could be limited.
Up to 3 marks maximum for each perspective, with an overall maximum of 4 marks.
Up to 2 marks for evaluation
- That clearly considers both viewpoints. For example, although population growth can increase aggregate demand, but higher costs, inflation, and unemployment may limit how much demand actually rises.
- Comes to a reasoned conclusion as to whether the likely impact of the change in Malaysia's total population on aggregate demand (reserve 1 mark)
No mark for evaluation can be awarded if just one perspective is considered.
