One of the most eminent challenges facing the world today is the ageing of our societies. The United Nations (2007) predicts that by 2050 the number of people aged 60 and older in developed countries will have increased from 21% today to 32%, and in the less-developed countries from 8% today to 20%. This will have profound implications for labour markets, aggregate demand, politics and societal structures. In addition, ageing societies will significantly challenge the affordability of traditional pension and healthcare systems. New approaches and new solutions from both governments and the private sector are required.
