AROUND the world nowadays, persistent unemployment, skill mismatches, and retirement frameworks have become central to fiscal policy — and to the often-fierce political debates that surround it. The advanced countries are facing an immediate "aging" problem, but most of the emerging economies are also in the midst of a demographic transition that will result in an age structure similar to that of the advanced economies — that is, an inverted pyramid — in just two or three decades. Indeed, China will get there much sooner.
Multiple problems affect employment. Weak demand in the aftermath of the global financial crisis that began in 2008 remains a key factor in Europe, the United States, and Japan. But longer-term structural issues are weighing down labour markets as well.
Most important, globalisation results in a continuous shift of comparative advantage, creating serious adjustment problems as employment created in new activities does not necessarily compensate for the loss of jobs in old ones. In any case, most new jobs require different skills, implying that workers losing their jobs in dying industries have little hope of finding another one. Moreover, technological progress is becoming ever more "labour-saving," with computers and robots replacing human workers in settings ranging from supermarkets to automobile assembly lines. Given the volatile macroeconomic outlook, many firms are reluctant to hire new workers, leading to high youth unemployment throughout the world. At the same time, aging — and the associated cost of health care for the elderly — constitutes the main fiscal challenge in maturing societies. By the middle of this century, life expectancy at age 60 will have risen by about ten years relative to the post-World War II period, when current retirement ages were fixed. Marginal changes to existing arrangements are unlikely to be sufficient to respond to technological forces, reduce social tensions and young people's fears, or address growing fiscal burdens. A radical reassessment of work, skill formation, retirement, and leisure is needed, with several principles forming the core of any comprehensive reform. For starters, skill formation and development must become a life-long process, starting with formal schooling, but continuing through on-the-job training and intervals of full-time education at different points in life. Special youth insertion programmes should become a normal part of public support for employment and career formation, with exemption from social-security contributions for the first one or two years of employment. A second principle is that retirement should be a gradual process. People could work an average of 1,800-2,000 hours per year until they reach their 50's, taper off to 1,300-1,500 hours in their early 60's, and move toward the 500-1,000 range as they approach 70. A hospital nurse, an airplane crew member, or a secondary-school teacher, for example, could work five days a week until her late fifties, four days a week until age 62, three days until age 65, and perhaps two days until age 70.
Employers and workers should negotiate such flexibility, but they should do so with incentives and financial support from government – for example, variable social-security and income taxes. Paid holidays can be 3-4 weeks until age 45, gradually increasing to 7-8 weeks in one's late 60's. Maternity and paternity leave should be increased where it is low, such as in the United States.
Public policies should also encourage greater scope for individual choice. For example, every ten years, a worker should be able to engage in a year of formal learning, with one-third of the cost paid by the employer, one-third by public funds, and one-third by personal savings (these proportions could vary by income bracket).
The overall objective should be a society in which, health permitting, citizens work and pay taxes until close to the age of 70, but less intensively with advancing age and in a flexible manner that r
