michael c bonello : population ageing - a major challenge for policymakers speech by mr michael c bonello, governor of the central bank of malta, at the opening session of two workshops on pension reform, organised in floriana, malta, by the world bank institute, 9 june 2003. * * * i should first of all like to thank the world bank institute for choosing malta as the venue for this workshop and to welcome you all to our country. your presence here continues a centuries - old tradition whereby malta exploits its location at the centre of the mediterranean and its reputation for hospitality to bring people and ideas together. malta is currently undergoing a rapid transformation in a bid to seize the opportunities arising from accession to the european union and from the further consolidation of its trading relationship with its southern and eastern neighbours. the economy, albeit small, has a number of vibrant sectors ranging from high - tech manufacturing to world - class conference tourism. as in the case with many other countries, however, the long - term prospects for economic development in malta will be inevitably affected by the impact of population ageing. given that the population support ratio, defined as the number of persons of working age to those of pension age, is expected to halve over the next 25 years to just over 2, this impact is likely to be significant. the global and regional dimensions of population ageing malta is by no means an exception in this regard. by the middle of this century, the median age of the world population is expected to increase by 10 years to 36 years. globally, the proportion of persons aged 60 years and older is forecast to double. the fastest growing group of the older population is made up of those who are 80 years old or more. this age category is projected to increase more than five - fold over the next 50 years. while ageing is indeed a global phenomenon, it is likely to represent a more onerous challenge for developing countries than for developed ones. the majority of persons aged 60 and over will be found increasingly in developing countries ; and as the pace of population ageing is much faster in these countries, they will have less time to adjust to its effects than the developed countries. developing countries, moreover, will have to meet this challenge starting from a lower level of socio - economic development. for instance, the elderly in developing countries will be living mostly in rural areas and hence will face additional difficulties compared to their counterparts in developed countries who tend to live in urban centres. these differences imply that the

policymaking capacity of developing countries will be tested more severely. more specifically, there will be important decisions to take regarding social security schemes, particularly traditional pension systems in which today ’ s workers pay for the benefits of today ’ s retirees. this will no doubt involve making difficult choices, some of which may have painful consequences in the short run, but which are essential for sustained economic development. the economic consequences of population ageing this is the case because population ageing is expected to have wide - ranging and long - lasting economic effects, involving not just government revenue and expenditure but also national saving and investment ratios as well as the labour market. the main issue that comes to mind when mentioning population ageing is its impact on government finances. most countries, including malta, presently operate pay - as - you - go pension systems. the ageing phenomenon undermines the financial viability of pay - as - you go systems by reducing the number of contributors relative to beneficiaries. ageing also entails increased government expenditure on health, and especially on the care of the elderly. the challenge to public finances is even greater if, as is the case in malta, the budget is already in deficit. changes in the age distribution of the population are also likely to affect a country ’ s private consumption and saving patterns. the ‘ life - cycle hypothesis ’ suggests that individuals tend to even out consumption outlays over their lifetime, such that a person saves during the working years in order to finance consumption during retirement. a rising trend in the proportion of elderly people, therefore, tends to be accompanied by a decline in the national saving ratio. oecd projections, in fact, point to a reduction in saving rates of between 5 and 12 percentage points of gnp over the period 1980 to 2025. such a contraction could lead to a vicious circle, as the resulting higher interest rates reduce investment, adversely affecting economic growth and, in turn, the ability to finance social security commitments. ageing could also have a negative impact on financial markets. pension funds are at present major players in most stock markets. as the baby boom generation retires during the current decade, most of these funds will have to gradually liquidate their assets, probably leading to downward pressures on share prices. this would in turn create a negative wealth effect, as declining asset prices dent the purchasing power of households and give rise to a reassessment of consumption patterns. the simultaneous decline in fertility rates, meanwhile, is expected to
