United Kingdom: Research Suggests Higher Proportion of Older Workers Can Lower Overall Productivity

A research paper finds that, in the United Kingdom, the higher the proportion of over 50s in the workforce in a local authority area, the lower the overall level of productivity. In "Does ageing matter when it comes to workforce productivity?," the International Longevity Centre–UK suggests that this "may be because work suffers from diminishing returns: that for every additional year worked, there is a relatively smaller gain in output."

The paper also argues that whilst rising life expectancy and other factors might raise the age at which productivity peaks, the broad shape of a worker’s lifetime productivity curve is likely to remain, so that a higher share of older workers will likely drag down overall levels of productivity.

According to Ben Franklin, the Centre's Assistant Director of Research and Policy:

With reference to English Local Authority data, this report provides support to both prevailing conclusions in the economic literature regarding the impacts of ageing on productivity. An older workforce may be a drag on output, but an ageing population could raise the rate of productivity growth.

In any case, investment in education and health are likely to remain critical drivers of long run productivity. Both are strongly correlated with the productivity performance of local authorities in our analysis, and focusing on the health and education of the workforce, irrespective of age, is therefore likely to support higher levels of economic output.

Research: Cognitive Aging May Not Link to Declining Productivity

According to a review of recent research comparing the productivity of workers in their 20s to workers in their 30s, 40s, 50s and 60s, age appears to be unrelated to performance in most occupations. This is contrary to suggestions that cognitive aging might hinder working longer due to declining fluid intelligence. In an Issue Brief--"Cognitive Aging and Ability to Work"--by Anek Belbase and Geoffrey T. Sanzenbacher, the authors note that :

• key reasons are that declining fluid intelligence is often offset by accumulated knowledge, and reserve fluid capacity can act as a buffer against decline; and
• only a minority of workers are vulnerable: those in jobs that require very high levels of fluid intelligence, and those who experience cognitive impairment.

Furthermore, "as people age, improvements in knowledge appear to largely offset declines in fluid intelligence, and the amount of fluid capacity that most workers have through their late 60s seems to offer a sufficient buffer against any declines."

However, some groups of older workers are vulnerable to cognitive decline. Workers in jobs that require a high degree of fluid intelligence (which can include those who end up shifting careers) or who experience a cognitive impairment are likely to have trouble extending their work lives.

As policymakers consider ways to encourage working longer, they may want to pay close attention to the potential impact of any proposed changes on such workers, as well as the effects on disability and unemployment programs that could see increased demand.

AgeUK Literature Review Finds Someone’s Age Bears No Relation to Worker's Ability To Do Most Jobs

A literature review conducted by AgeUK reports that someone's age bears no relation to their ability or capability to perform the vast majority of jobs. Thus, AgeUK recommends that employers reconsider their existing workforce and HR strategies, and develop more effective retirement policies that place the wellbeing of their older employees at the heart of the process.

In its review, AgeUK finds, among other things that:

• The evidence shows either a lack of relationship between productivity and age, or that older workers are at least as productive as their younger colleagues. Even in physically
  demanding situations, for example on a factory production line, age is no barrier to working productively.
• Measuring individual productivity is challenging for researchers. Older studies, which often suggest older workers are less productive, frequently rely on outdated assumptions about aging and health, or fail to account for a myriad of other factors. More recent studies, which often find older workers are at least as productive as younger workers, are better able to account for these.
• As people age some cognitive and physical abilities do change—however, this does not
  make older workers better or worse than younger colleagues. There is no evidence of a substantive decline in ability in most people until well past the end of a typical working life. Aging affects everyone differently, and it is not possible to make predictions about any one individual’s capability.
• The interaction between skills, knowledge and experience means that many tasks can in fact be performed better as people age, and raises challenges for employers about how best to utilize individuals’ skills and abilities.
• Recognizing the challenges faced by older workers and offering solutions to mitigate them, for example flexible working to help people meet caring responsibilities, can help enhance individual productivity.

United Kingdom: Study Shows Older Workers Are as Productive as Younger Counterparts

According to research released by AgeUK, despite assumptions made by many employers, older workers are motivated and willing to work as flexibly as younger workers. The research investigating the evidence behind common perceptions about older workers was carried out by Essex Business School, University of Essex.

Among other things, the review found that, while there was evidence of decline in some physical attributes in some, but not all, older workers, there was little sign of a decline in overall productivity because older workers compensated with skills and experience. Furthermore, while there is evidence to suggest that while younger people might be typically faster at carrying out repetitive tasks, older people are often faster at carrying out complex tasks that allow them to draw on their contextual knowledge and years of work experience.

Dr Kathleen Riach, Reader in Management at Essex Business School who carried out the study said, ‘Our review found that stereotyped perceptions about older workers don’t stand up to scrutiny.

'Our work indicates that age doesn’t determine a person’s commitment and productivity levels at work. Other socioeconomic and psychological factors are much better indicators of the way older people behave.’

Research: Older Workers are Not Bringing Down Average Wages, Help Workforce Producitivity

According to research from The Brookings Institution, an aging workforce had not dragged down average worker productivity over the past quarter century in the United States. Instead, Gary Burtless, Senior Fellow, Economic Studies, reports in "The Impact of Population Aging and Delayed Retirement on Workforce Productivity," that improved education among the population past 60 and delays in retirement among better educated Americans have tended to boost the earnings of older workers compared with younger ones.

Using one standard benchmark of individual worker productivity—hourly wages—workers between 60 and 74 now earn more than an average worker who is between 25 and 59. The hourly pay premium for older men was about 22 percent in 2011. For older women it was about 10 percent. Other earnings benchmarks show a somewhat less favorable picture, but all of them show considerable improvement in the relative position of aged workers compared with the nonaged over the past two decades. None of the indicators of male productivity suggest that older male workers are less productive than average male workers who are between 25 and 59.

Burtless points to two factors for the surge in older workers’ earnings: (1) the sheer size of the baby boom generation means that the number of Americans attaining age 60 each year is climbing steeply; and (2) labor force participation rates of adults between 60 and 74 have increased.

Burtless also notes that a major reason for the surge in income is that older workers are now better educated compared with prime-age workers than was the case in the past. "Twenty-five years ago the gap in education between prime-age workers and older Americans was large. Americans past 60 had much less schooling than workers who were younger. That gap is now much narrower."

Israel: Research Finds that Professional "Vitality" Peaks at Ages 50 to 59

According to the results of research announced by the University of Haifa, managers demonstrate their highest levels of professional vitality in their 50's. In an investigation of the functionality of high-tech, engineering, and infrastructure executives, Dr. Shmuel Grimland, Prof. Yehuda Baruch, and Prof. Eran Vigoda-Gadot, found that in terms of vitality--defined as " the ability to carry out tasks with passion, vigor, and competence, and to gain satisfaction from his or her work performance", advancing age plays a significant role.

Specifically, the older the manager, the higher his or her professional vitality, reaching a peak at 50-59 and 57 being the highest point in the sample group. Then, the manager’s vitality then begins to drop.

"Our study shows that providing tools for workers to improve their professional vitality will also improve their satisfaction and will help cultivate resourceful and innovative workers. This indicates that an organization should make it a priority to provide such tools. Workers’ vitality ‘fuels’ the success of the organization, and the fact that professional vitality is preserved and actually rises well into one’s 50s indicates that organizations investing in this aspect of the workplace will be able to benefit from productive workers for many years," the researchers concluded.

New Zealand: Preview of Study Challenging Perception of Older Workers as Less Productive

Although New Zealand's Equal Employment Opportunities Trust report on "Older Workers: Challenging Myths and Managing Realities" is not due out until mid-2012, a preview has been published about the research finding that there is no direct relationship between older age and productivity--but productivity could be worsened by age discrimination. According to the Sunday Star-Times, the report suggests that older workers are seen as less productive, less able and less worth the expense of upskilling--and that younger bosses in particular might benefit from "age management" training.

The article quotes EEO researcher Dr Mervyl McPherson:

"There is more difference between individuals within the same age group than there is between age groups in productivity, health, ability to learn," she said.

"Keeping older workers [employed] means they are still working and paying tax, and that offsets some of the demands that the babyboomers are going to be making in terms of welfare and superannuation and health."

While more detailed recommendations will be included in the final report, McPherson mentioned better working flexibility and more upskilling of older workers, along with wider options for "bridge employment"--options that allow people nearing retirement to move into less responsible, part-time or project-based roles. According to her, an employer was frequently more likely to get another five or ten years' service from someone who re-trained at 55 or 60 than from a younger person who then quickly moved on.

Low-skilled workers at each end of the age spectrum suffered in downturns--and McPherson said that was an issue for older workers coming out of industries where their skills were defunct, such as manufacturing.

"They are the ones most in need of work because they are on low incomes and so they are probably less prepared for retirement. But they haven't got the skills for the current economy," said McPherson.

The report suggested they might face discrimination when it came to who was chosen for retraining--or consider themselves not worth the expense.

Research: Productivity of Older Workers Decreases with Age, but Decline is Limited

A Dutch labor economist looking at age effects at the individual level by analyzing data on running and publishing in economic journals has concluded that the productivity of older workers indeed decreases with their age, but that the decline is limited, and found no evidence of a pay-productivity gap at higher ages. In "Will You Still Need Me: When I’m 64?" (De Economist), Jan C. Van Ours, of Triburg University, undertook the study to test the perception whether older workers without jobs have a harder time finding one because of A gap between wage and productivity--that is, older workers having a wage that is higher than their productivity.

To shed some light on the relationship between age and productivity I analyzed panel data on individuals and firms. To the extent that running performance represents physical productivity I find evidence of a productivity decline after age 40. To the extent that publishing in economics journals represents mental productivity I do not find evidence of a productivity decline, even after age 50. When measured at the firm level I find little evidence of an increasing pay-productivity gap at higher ages of the workforce.

Van Ours acknowledges that there are limitations of the empirical analysis, but nevertheless believes that while "the potential negative effects of aging on productivity should not be underestimated; they should not be exaggerated either." In particular, there "is no need to worry too much about age-related productivity declines or an age related pay-productivity gap." However, since older workers are not very likely to return to a job after becoming unemployed, he suggests that the labor market position of older workers will remain an area of policy concern.

Opinion: Call for More Research on How Older Workers Respond in Actual Working Conditions

Stating that too little is known about how workers manage job demands as they age and begin to lose physical and cognitive abilities., Business Insurance is calling for adequate research into older worker performance conducted in real workplaces, where all the workaday pressures are present. While there is widespread agreement that knowing more about older workers is important for employers, most studies on aging-worker performance have been completed in quiet lab environments where people are asked to complete specific tasks.

That means employers don't know enough about how aging employees are accommodating for declining capabilities. Are they jerry-rigging devices to help them lift loads or creating platforms that help them step over obstacles?

If employers are not directing such accommodations, it is possible individual worker efforts could actually be creating safety hazards for themselves and other employees.

Perhaps there are better ways to accommodate that could increase productivity. Research could help answer such questions.
