You are watching: What 1970s legislation was passed that significantly affects the elderly?

National research Council (US) Committee top top Population; martin LG, preston SH, editors. Demography that Aging. Washington (DC): nationwide Academies push (US); 1994.



The change from work to retirement has actually long to be a significant concern of public policy experts and practitioners. All modern industrialized countries and many occurring countries have produced policies to reduce the threat of earnings loss because of retirement. Yet in for this reason doing, they have actually fundamentally transformed the reward framework of work and also retirement throughout the life-cycle. The resulting alters in the job force behavior of older world have to be dramatic. In this chapter, we testimonial recent economic research on this issues and also outline the locations we think need added research. We carry out so from the perspective of the joined States, while recognizing the the labor force trends uncovered here space not unique and also that cross-national to compare of publicly policy and also its aftermath are advantageous inputs because that understanding and also developing residential policy.

Cross-national comparisons are ideal because many industrialized countries have denote retirement policies that discourage work-related at older ages. In the critical decade, these plans have started to change. In the unified States, because that instance, recent legislation has actually outlawed mandatory retirement, banned the cessation of company year credits in pension calculations after ~ a details age, and also increased the Social security credit for delayed retirement after ~ the age of 65. One intent of these transforms is to do the retirement device age-neutral through respect come work; that is, to end the age-specific penalties because that work beyond specified eras that space imbedded in our current retirement system so the the life time value that retirement benefits will not rely on the age at which castle are very first claimed.

But a more an essential force is most likely to impact retirement policy in the future—the aging that postwar baby boomers. The joined States and Germany have currently enacted transforms in their main retirement insurance systems that will raise the age of regular retirement early on next century. A review of previous policies will certainly be valuable as we lay the groundwork because that retirement plan in the twenty-first century.

Our conversation of retirement policy extends past the Social protection retirement program. In many countries, and also certainly in the joined States, society Security disability programs provide a leg to retirement for few of those as well young to qualify for retirement benefits. This protection raises the same financial incentive concerns that are the focus of lot of the retirement research. Hence, in looking in ~ labor pressure participation at older ages, we should look at the full impact of the social welfare system on work decisions.

Retirement plan extends well beyond government transport programs. Private contracts in between employers and also employees can also alter the incentives to work-related at older ages even when explicit wage rates perform not change. Employer pension plans and health benefits also influence the retirement patterns of larger workers. Federal government attempts to change these contracts provide another topic because that public policy analysis.

Below, we first document some global trends in labor pressure participation in ~ older ages and review the literature that has attempted to define them. We find that although many workers have a an option with respect come retirement age, the choice is constrained by personal health factors, government retirement and disability policies, and also employer pension plans. The significant debates in the literary works are not around the existence of such constraints but rather about the magnitude of your impacts. We finish by saying how job force behavior may readjust as brand-new cohorts of enlarge workers arise in the following century, and also outlining the research and data that will be required to track this behavior.

The joined States

The retirement tendency of larger Americans end the critical several years is dramatic. A simple measure is the labor force participation rate—the proportion of those to work (full-time or part-time) or actively searching for occupational to the civilian noninstitutionalized population. Number 3-1 mirrors U.S. Participation prices from 1964 with 1992, because that cohorts of males aged 45-49 through 70+. For men aged 60-64, which consists of the earliest age of eligibility because that Social security retirement services (62), participation has dropped nearly a third, indigenous 80 to 56 percent. For guys aged 65-69, the decrease is around 40 percent, and also for those 70 and over, the authorized rate has actually dropped one-half. The trends are much less striking because that the younger groups, however even those aged 55-59 have actually dropped 10 portion points, with much more modest declines for those age 45-54.

United says male labor force participation prices by age, 1964-1992. SOURCE: bureau of job Statistics, Employment and Earnings, January issues.

For women, the fads are less precipitous, due to the fact that two offsetting phenomena space at work. World are retiring earlier, yet women, especially married women, are much more likely to work than previously. For the earliest female cohorts (aged 60 and older), the resultant trends are level (see figure 3-2); because that the younger groups, the latter dominates, and also participation prices are top top the rise.


Figure 3-2

United states female labor pressure participation rates by age, 1964-1992. SOURCE: office of job Statistics, Employment and also Earnings, January issues.

The U.S. Department of job gathers some labor force data by individual ages. Number 3-3 shows participation rates for men aged 60-65, i beg your pardon include vital ages for Social security (62 and 65) and also for countless employer pensions (age 60). The long-run trend deserve to be seen in 2 ways—the decrease for each age over time and also the readjust in the most prominent single- year gap. In 1968, the biggest behavioral readjust occurred in between ages 64 and also 65. Now, the biggest adjust is between ages 61 and 62. A space at period 65 remains, however much of the job force exit has currently occurred.


Figure 3-3

United states male labor force participation rates, ages 60-65, 1964-1990. SOURCE: Unpublished data, U.S. Department of Labor.

The many recent data suggest that the tendency toward previously retirement in the United says may have stopped or even reversed. For every one of the period categories that men over age 50 in figure 3-1, participation prices over the previous 5 years space virtually unchanged. Because that 11 of the 16 separation, personal, instance ages in between 55 and also 70 (and for 8 the 10 eras over 60), masculine participation prices were actually higher in 1990 보다 in 1985.

In summary, men are leaving the labor pressure much earlier than lock were even two years ago, yet there has been little change in the past few years. (As we see below, however, the trends may be continuing still, yet in another guise—reduced hours of those employed.) Women"s retirement trends are being counter by a rising tide of female labor force participation in general.

Other organization for financial Co-operation and advancement (OECD) Nations

The beforehand retirement trend can be watched in other industrialized nations together well. The participation prices differ by country, as do the magnitudes that the declines, but the basic pattern is the same—people space retiring previously than they supplied to.

Table 3-1 mirrors the employment-to-population ratio for 16 OECD countries, indigenous 1966 come 1990, for men aged 55 and also over.1 The present figures variety from 11 percent in Italy come 60 percent in Japan, v most nations in the 30-40 percent range. Yet every among these countries except Japan has seen a far-ranging fall. The U.S. Decrease (about 30% end these 24 years) is typical.


Figure 3-4 reflects employment to populace ratios by age (55-59, 60-64, and 65+) for guys in eight selected OECD nations in 1975, 1980, 1985, and also 1989 (1987 because that West Germany). For the youngest group, these ratios in 1989 ranged from about two-thirds in the Netherlands to much more than 90 percent in Japan. End the past 15 years, the decreases ranged indigenous 13 to 15 clues (Australia, France, the Netherlands, and also the joined Kingdom) to much less than 1 point (Germany and also Japan).

Figure 3-4

Male employment to populace ratios in eight OECD countries, 1975-1989. SOURCE: OECD, employed Outlook (various years).

Employment rates are substantially lower for the cohort of males aged 60-64—from around 20 (Japan and also Sweden) to 25 (Australia, Sweden, united Kingdom, and also United States) to more than 40 points reduced (France, Germany, and the Netherlands)—than they are for men aged 55-59. The rates range from a short of around one-quarter (France and also the Netherlands) to more than 70 percent in Japan. The declines since 1975 have likewise varied greatly, from around 10 percent in Japan, Sweden, and also the United claims to more than 40 percent in the Netherlands.

With the exception of the Japanese, sector work is currently rare among men aged 65 and over. In Japan, an ext than a third of these men still work, and in Sweden and the unified States, one in six or one in 7 do. Yet in the other countries shown, fewer 보다 10 percent room employed. In France, Germany, and also the Netherlands, the figure is closer come 5 percent. Compared to men aged 60-64, number of of the cohort drops are precipitous—more than 40 percent points in Australia, Sweden, and also the unified Kingdom. A current study through the OECD (1992:Chapter 5) argues that these early retirement patterns are due to various combine of clear incentives in nationwide social security and also disability programs, work-related pensions, and also collective bargaining agreements.

Several review points emerge. In all of these countries, male employment prices drop dramatically between the eras of 55-59, once the vast majority of guys are tho working, and also 65 plus, when work is the exception, no the rule. The period at i beg your pardon the decrease occurs varies. Some nations have substantial participation declines at eras 60-64 (France, Germany, and also the Netherlands—all more than 40-point drops), and the others have actually a large decline at periods 65 and over (Australia, Japan, Sweden, the unified Kingdom, and also the unified States—all an ext than 35-point drops). Second, the trend toward earlier retirement is it was observed everywhere, but in countless countries choose the joined States, it has tapered turn off in recent years. Third, U.S. Participation prices are common for guys aged 55-59 and 60-64, but reasonably high for males 65 and also over. Finally, Japan was standing out together an exemption on job-related at older ages, through the highest possible rates for all three period cohorts; it is the only one of these nations in i m sorry one-third of guys over 65 proceed to work.

The fads for females are much more varied. Table 3-2 reflects employment to population ratios for females aged 55 and over in the exact same 16 OECD countries. In some (such together Canada, Australia, Italy, Japan, and also the joined States), there has actually been small change end the past 20 years. Rather (Finland, France, West Germany, Spain, and also the joined Kingdom) have had actually the same declines observed v men. Just in Sweden has actually older women"s employment raised steadily.

Women additionally show far-reaching labor force withdrawal together they age, although much less so in the United states than in most of these other countries. Just in Canada, Japan, Norway, Sweden, and also the United claims are more than one-third the the ladies still functioning at eras 60-64 (not shown); for ladies aged 65 and over, participation rates are in the single digits for every 16 countries, except Norway and also Japan.

The joined States

Not just do fewer older Americans occupational than previously, but those who carry out are much more likely to occupational part-time. In the unified States, the prestige of part-time occupational rises substantially with age. Although only 7 percent of to work nonagricultural guys aged 25-60 work part-time (fewer than 35 hours per week), 16 percent the those aged 60-64 and nearly half of the males aged 65 and also over carry out (Bureau of job Statistics, 1992:Table 33). For women, part-time job-related is much more prevalent at every ages, and also shows a similar age differential. Whereas only about 20 percent that the employed females aged 25-54 work part-time, a quarter of those period 55-59, much more than a third of those 60-64, and also 60 percent that the women 65 and over perform (Bureau of job Statistics, 1992:Table 33). The vast majority of the larger Americans functioning part-time say they space doing so voluntarily (Bureau of job Statistics, 1992:Table 33).

Among larger Americans, the proportion functioning part-time has actually been growing over time: for males aged 65 and also over, indigenous 38 percent in 1970 come 49 percent today; because that women, indigenous 50 come 60 percent.2 In this sense, the at an early stage retirement trend might still it is in under way, however through hours rather 보다 labor force participation.3

Other OECD Nations

Part-time employment additionally appears to be on the increase in other occurred nations. The OECD (1983:44; 1991:46) has approximated the extent of part-time employed staff in member nations in 1973, 1979, 1981, 1983 and also 1990. In every case, the ratio was higher in 1990 than in 1973. In most cases, the increase was secure over this time period.

There is good variation in the degree of part-time work in OECD countries. Amongst all to work men, the ratio part-time ranges from 2 percent or much less in Austria, Belgium, Germany, Luxembourg, and also Spain to nearly 16 percent in the Netherlands (OECD, 1991:46). Among employed women, the proportions are constantly much higher, varying from around 10 percent in Finland, Greece, Italy, and also Portugal to virtually 50 percent in Norway and more than 60 percent in the Netherlands.4

Most of the part-time job-related in this countries shows up to be voluntary. The OECD (1990:182) approximates that about two of 3 male and also four of five female part-timers want to work much less than full-time. If the United says is any kind of guide, the percent voluntary would certainly be even higher for the older part-time workers.

Figure 3-5 reflects the percentage of the elderly population that functioned part-time in eight OECD countries in 1989 or 1990. This proportion combines two factors: the percentage of world who work and the percentage of those working who work-related part-time. Several interesting conclusions emerge. Amongst older men, part-time job-related is inconsequential in Germany and France. In both countries, the vast bulk of guys are out of the labor force altogether by age 60 and, especially in Germany, very couple of of those that remain work part-time. Only 3 percent of enlarge Frenchmen (55-64) and also 1-2 percent of older Germans are part-time employees. In contrast, part-time work among the elderly seems to be very common in the Netherlands (at periods 55-59) and in Japan and Sweden (after age 60), whereby 13 and 19 percent of all men aged 60-64 work-related part-time. The United states is in the middle, since neither our retirement endure nor ours part-time employed staff experience amongst the yonsei is extreme.

Figure 3-5

Percentage the the populace working part-time in eight OECD countries, through age and also sex, 1989-1990. SOURCE: OECD, employed staff Outlook (various years).

For women, the relative U.S. Experience relies on the period group under discussion. Because that those aged 55-64, we are at the low end of the spectrum, not because our labor pressure participation prices are particularly low, but because relatively few of those employed occupational part-time. By period 60-64, however, the joined States, through 12 percent the the population working part-time, is much an ext typical. We have actually moved come the center of the spectrum because of the much much more abrupt retirement patterns amongst women in other countries. In Germany, France, and the Netherlands, less than 7 percent that the females aged 60-64 room employed part-time. In contrast, 16 percent that British and Japanese ladies are, and practically one-third the those in Sweden.

What emerges is that part-time employed staff is an essential part the the labor force withdrawal process in many emerged nations. The U.S. Experience is in the middle of the spectrum; some nations have a lot much less elderly part-time employment and also others a lot of more. Since an ext older american say they desire to work-related part-time 보다 actually do, us may have actually much to discover from other nations who have actually been more successful in permitting employees to withdraw gradually from the job force.5

The beforehand Survey literary works on Retirement

The at an early stage literature explained retirement transitions the were mainly thought to it is in involuntary.6 that emphasized the prestige of negative health, layoffs, and mandatory retirement plans in the tap the money process, and also was based mainly on surveys and analyses done by the U.S. Society Security administration (SSA).7

For example, Wentworth (1945) analyzed a survey of nearly 2,400 male Social protection beneficiaries that were request why castle quit working. Much much more than half said they had been set off, and also another third claimed to have retired for reasons of health. Less than 5 percent that the respondents seemed to have retired voluntarily if in an excellent health. A couple of years later, Stecker (1951) summarized the Wentworth study and also three various other surveys indigenous the 1940s. She uncovered that the overwhelming majority of Social protection beneficiaries left their last extended employment due to the fact that they had lost their tasks or had actually quit for health and wellness reasons. Only about 5 percent left since they ""wanted come retire." Stecker (1951:15) concluded that "most old civilization work as long as they can and also retire only due to the fact that they are required to do so."

In 1951, SSA surveyed an ext than 15,000 retired beneficiaries aged 65 and over. Nearly 85 percent had actually either shed their last task or quit since they to be unable to work. Stecker (1955:12) concluded that "voluntary quitting to gain a life of recreation is rare among old age beneficiaries. Relatively few who room able to work select retirement."

In 1963, SSA surveyed both beneficiaries and nonbeneficiaries as young as period 62, and a tendency toward much more voluntary retirements was first noticed. About 28 percent the the wage and also salary workers had retired because that voluntary reasons, around twice the percentage in the 1951 survey. Palmore (1964:3) stated that "although most guys retire involuntarily—because of poor health ... Or due to the fact that they have actually reached a compulsory retirement age—voluntary retirements are increasing." Epstein and Murray (1967:105) agreed the "here seem come be more and more aged men who are well enough to work and also who might get some type of task if they to be interested, however who choose the leisure of retirement."

In 1971, Reno reported on a brand-new survey of current Social protection recipients, in i beg your pardon those not working were request why lock left your last jobs. Nearly fifty percent said health, one more quarter provided job-related reasons, and 17 percent said they wanted to retire. Yet in another component of the survey, almost a third said the they left your last job since they want to start gaining Social protection or a pension, arguing that gaue won considerations can be important.

Reno additionally found that the proportion that wanted come retire increased directly with the size of their retirement benefits. She concluded that "... Financial considerations often underlie the willingness through which men retire early" and also that "the level that retirement benefit income had an important influence ~ above the men"s willingness to accept or initiate early retirement" (Reno, 1971:12-13).

More recently, Packard and Reno (1989) reported on a 1982 survey of brand-new Social defense beneficiaries, in which answers said that an ext retirements to be voluntary 보다 involuntary. The proportion voluntary climbed with the age of retirement (up to age 65) and also was much greater for those with pensions. Overall, about one-third said that they want to retire, an ext than the quarter that named health and wellness as the main reason.

The at an early stage Econometric Literature

Economists room interested in the duty of incentives. Survey responses and also circumstantial evidence argued that gaue won incentives might be important in the retirement decision. Retirement and also early retirement rates rose significantly in the United claims as social Security and also employer pension equipment expanded. Noticeable changes in labor pressure behavior occurred at ages important in pension and also Social protection rules—60, 62, and 65. Workers" wage revenue were discovered to cluster approximately the levels at i m sorry the social Security earnings test went into effect.8

The early on econometric literature hypothesized that numerous retirements are labor supply choices—individuals law what they judge finest given the choices they face. The early studies were, in retrospect, unsophisticated in a number of ways. They were one-period labor-leisure models that ignored the crucial multiperiod nature of pension and also Social defense promises, and also they made use of very an easy measures of the gaue won incentives dealing with those contemplating retirement. Nonetheless, they succumbed reasonable outcomes that began to change the embraced wisdom on the procedure of retirement, and also they urged a overwhelming of much more sophisticated research.

Quinn (1977) published among the earliest econometric research studies using the Social security Administration"s Retirement background Study (RHS). Using only the an initial cross-sectional wave of about 11,000 men and also (nonmarried) females aged 58-63 in 1969, he discovered that present labor force status (in or out) depended on health, the existence of dependents, legacy income, regional labor industry conditions, particular job characteristics, and most essential for our purposes, eligibility because that Social protection and/or employee pension benefits. Those right now eligible for benefits were much much more likely come be out of the job force. Yet the research ignored the dimension of the benefits and also how these services might adjust were the individual to work-related for an additional year.

Boskin (1977) studied a little sample the older men from the Panel examine of revenue Dynamics and also estimated the maximum social Security benefit for which each family members would it is in eligible. The results argued very solid Social defense effects—the larger the potential benefit, the more likely the person was to retire. Unfortunately, he had no info on pension eligibility or benefits, and also ignored the truth that the benefits would increase if retirement to be delayed.

Burkhauser (1979, 1980) to be the very first to emphasize the multiperiod nature of social Security and pension rights, and also argued the the about theory appropriate and empirically important concept was no a dichotomous eligibility variable (as in Quinn, 1977) or the size of the yearly benefit (as in Boskin, 1977), however rather the existing discounted value (PDV) that the entire benefit stream. He showed that this PDV (or alters in it, called pension accrual—see below) was critical determinant in the decision that autoworkers contemplating an early pension and of other workers considering at an early stage Social security benefits at age 62.

The an essential insight here was to view retirement earnings rights as an asset, a stock of wealth, that could rise or fall depending upon when the benefit was claimed. When the receipt that a retirement advantage is delay (e.g., through working an additional year), two points happen. The negative news is that existing pension revenue is forgone, say, $10,000. The an excellent news is the future annual benefits will certainly be higher. Because that Social Security, they will certainly increase since average monthly earnings (on i m sorry benefits room based) will rise and because Social security adds a delayed retirement credit to every future checks. Because that defined benefit pension plans, benefits space usually based upon some combination of last or highest earnings and years that service, both of which are most likely to rise with ongoing work.

The choice, then, is no simply between a pension check and also no pension inspect in that theoretical year; rather, that is between two streams that income, one starting immediately, with smaller annual amounts, and also another commencing later, however with higher benefits every year. I m sorry is more valuable—more small checks or fewer big ones?

The answer counts on whether the future annual increments are adequate to compensate for the pension income initially forgone. If the increments just compensate, the pension is dubbed actuarially fair. If the future enhancements are an ext than sufficient, then one gains twice by functioning that additional year, both v the paycheck and also through the rise in pension or Social security wealth. But if the future increments space worth much less than the services forgone, climate pension wealth declines with added work. In this case, true compensation is less than the paycheck by the quantity of the wealth loss. This straightforward concept and the presence of several superior data set spawned the voluminous literature debated below.

The modern-day Econometric Literature

Economists have adopted two strategies to research retirement incentives. Most have used among the big microeconomic data set on older workers (such as the RHS or the job Department"s nationwide Longitudinal inspection (NLS)) to ask that retired, that did not, and also under what circumstances. The benefit of this approach is comprehensive demographic and also economic info on a big sample the potential retirees and accessibility to their Social Security earnings records. The disadvantage is scanty data on your employer pensions. The 2nd approach involves analysis of really pension plans, with all their detail; the price payment is restricted information on the world in the plans. Fortunately, this two methods yield similar conclusions.

Recent study has created that social Security and also many defined advantage pension plan contain solid retirement incentives (work disincentives) at specific ages. They carry out so with benefit calculation rule under i beg your pardon the future yearly pension increments following an additional year of work are inadequate to compensate because that the benefits at first forgone; in other words, the asset value of one"s Social security or pension declines with additional years ~ above the job. Through working, one earns a paycheck and simultaneously loser retirement revenue wealth. This is a diminish in network compensation—a pay cut—not via the paycheck, which would be illegal, but through the benefit calculation rules of social Security and also many employees" pension plans.

Accrual Patterns

Burkhauser and Quinn (1983a) and Quinn and also Burkhauser (1983) offered the RHS to calculation the size of the society Security and employer pension incentives in the mid-1970s. We found that Social defense wealth increased slightly with ongoing work because that the median full time worker at age 63 and also 64—future increments slightly outweighed the initial benefits forgone. However at age 65, since of the drop in the delay retirement credit transaction from about 7 to only 1 percent every year of delay (it is now 4%), Social defense wealth reduced sharply because that those who ongoing to job-related to period 66. The average wealth ns was about a third of yearly pay—a far-reaching pay cut indeed. The pension story was similar, return the estimates were less reliable since the RHS pension data to be much an ext limited.9

Fields and Mitchell (1984c) check the details that 14 certain pension plans and also estimated the incentives dealing with workers at each age in between 60 and 68. They discovered that the asset value of pension civil liberties tended to rise and then fall, peaking between the periods of 60 and 65. Through samples of males from among their pension plans and from the RHS, they calculated complete lifetime earnings (from period 60 on) for theoretical retirement ages in between 60 and 68—the amount of the present values of earnings, social Security, and also pension benefits. This total rises with annually of extr work due to the fact that earnings exceed retirement benefits. Yet the rise in the full (the true compensation because that the additional year that work) falls monotonically and also at age 68 is less than 40 percent that what it to be at period 60. This is the decreasing compensation profile facing older Americans.

Finally, Kotlikoff and Wise (1989) studied virtually 1,200 American plans and also found that pension accruals for the typical plan were an unfavorable for those who worked past the common retirement period in the plan. In countless pensions, accruals were an adverse after the earliest age of pension eligibility. They uncovered that it was not unusual for the annual loss in pension wide range to same 30 percent of annual wage earnings.

Because that this research, it is now typically agreed the retirement income rights are ideal viewed together assets whose values depend on as soon as they are an initial claimed. Changes in this asset values with ongoing work (pension accruals) are part of compensation, and wealth losses are equivalent to salary cuts. At some age—certainly through 65 however often lot earlier—accruals become negative, and also therefore net pay begins to decline, providing strong incentives to retire.

The influence of Retirement Incentives on Behavior

Considerable research suggests that numerous workers answer to these incentives by leaving career jobs, and often the labor pressure as well, when these pay cuts occur. Burkhauser (1979) showed that autoworkers were much more likely to leaving the firm together the pension wealth loss connected with continued work increased. Rhine (1984) found that employees in suppliers with attractive early-retirement services were more likely to retire at an early stage than those in carriers without such inducements. With a huge sample the older employees from the RHS, Burkhauser and also Quinn (1983b) uncovered the very same for both social Security and pension riches changes. Us concluded the at least half of what looked choose a causing obligation retirement result at period 65 was really because of the gaue won incentives that arisen at the very same time.

Burtless and Moffitt (1984, 1985, 1986) evidenced that the Social protection system influences labor supply behavior. They uncovered a dramatic clustering the retirement roughly the periods of 62 and 65, and showed the retirees who ongoing to work reported revenue clustered around the amount that Social protection permits there is no loss that benefits. Sickles and also Taubman (1986), likewise using the RHS, combined earnings and the readjust in Social defense wealth right into one variable and also found the it to be the most far-reaching of the earnings variables in explaining retirement behavior.

As stated above, Fields and Mitchell (1984b) supplied a very different methodology and a different data set, selecting to delve more deeply into the yes, really details that a small variety of pension plans. When the incentives and individual behavior were compared, lock concluded the those through the many to gain by postponing retirement tended to retiree later. Similarly, Kotlikoff and also Wise (1989) studied the employee of one certain firm for which lock knew specific pension details, and showed that leave rates at particular ages synchronized precisely with the discontinuities in worker compensation the resulted from society Security and pension plan accruals.

Because the two main microeconomic data sources for lot of the retirement research focused on men, over there is much much less literature on the retirement decision of women.10 In very recent work, Reimers and also Honig (1993a,b) and Honig and Reimers (1992) imply that (white nonmarried) women might be much more sensitive to these financial incentives 보다 men. According to their results, women have actually longer time horizons and are more likely to view Social defense in a long-run, present discounted worth fashion fairly than just looking at the level of present benefits. On the various other hand, in one of couple of other studies comparing actions by gender, Lumsdaine et al. (1994) find no statistically far-ranging differences in the retirement patterns of larger men and women employed by a large Fortune 500 firm; in particular, their response to a retirement bonus available for 2 months in 1983. This is an area in which study is long overdue.11

Gustman and Steinmeier (1994) have actually analyzed the impact of one more incentive—health benefits after retirement—on the time of the retirement decision. They find that workers tend to delay retirement at the very least until the day at i beg your pardon they come to be eligible because that these benefits, and then room slightly more likely come retire when eligible. The net impact is a really small decrease in average retirement age.

Exit trends from career Jobs

Researchers have actually recently started to analyze the exit routes that older american take in between full-time job-related on a job job and also complete labor force withdrawal. Although plenty of still do this transition in one step, numerous utilize one or an ext bridge jobs between the two. Despite the truth that most of the financial literature treats retirement condition as dichotomous, Americans actually leave their career work in many diverse ways.

Quinn et al. (1990) characterized a career task as permanent employment organized for at the very least 10 years. Complying with the RHS sample from 1969, once the respondents were 58 come 63 years old, until 1979, when the biennial surveys ended, we discovered that a substantial minority did no leave the labor pressure when castle left full time status on a career job. Among wage and salary workers, one-quarter did something else—most found brand-new employment and also a couple of dropped come part-time top top the job job. Amongst the self-employed, with much more control over the amount and kind of work they do, only fifty percent left the job force. One-quarter remained part-time on the very same job, and also the various other quarter found new work.

Most of these transitional work were an ext than short-lived employment. The those that switched employers, nearly three-quarters to be still top top the brand-new job a year later, and nearly 60 percent stayed after 2 years. A to compare of the career and bridge tasks revealed that many of the transitions connected movement to different occupations and industries. More people moved down the socioeconomic ladder—from experienced to unskilled and from white collar come blue collar—than moved up. There were many much more hourly wage cuts 보다 increases.12 There was weak evidence that those in ~ the ends of the economic spectrum were an ext likely to remain in the labor force after leaving job employment—the poor probably because they had actually to and also the rich because they wanted to.

Ruhm (1995) has actually analyzed a sample of guys aged 58-63 from a much an ext current data set—the 1989 Commonwealth/Harris survey—and contrasted his findings with those on males of the same age from the 1969 RHS sample.13 not surprisingly, the finds greater retirement prices today than twenty years ago. He likewise finds much larger employment drops in ~ the ages of 60 and 62 currently than there were then. These are important periods for pension and Social defense eligibility. In 1969, the cross-sectional employment rate dropped around 2 and 5 portion points at ages 60 and also 62, respectively; in 1989, the respective decreases were 13 and 18 points.

Ruhm also found considerable bridge employment. In between 30 and also 40 percent (depending ~ above the age) that those to work in 1989 were working on a postcareer bridge job, and for every ages however one, this percentages were greater in 1989 보다 they were for world the same age in 1969.

This research mirrors that dichotomous meanings of retirement, no issue what the an interpretation used (e.g., labor force participation, a large decline in hrs worked, receipt of pension or Social protection benefits, or self-defined status), miss much that the story. Retirement paths in America room many and varied. The stereotypical transition—directly from full-time work to full-time leisure—is only component of the story. A substantial minority that Americans carry out something other than leave the labor pressure when they leave their career jobs. For many, the shift involves part-time employment, typically on a brand-new job, in a brand-new line that work, and at lower pay. There are offsetting advantages, such as flexibility of hours, different working conditions, and for many, the capacity to insurance claim a career task pension as soon as its asset value is in ~ its peak.14

Uncertainty, option Value, and also Dynamic Programming Models

Most retirement models implicitly i think a civilization of certainty in which world base decisions on their current situations and their best estimates of the future. In fact, however, there room probability distributions approximately these finest estimates, and these distributions adjust over time. Health deserve to vary, and also layoffs deserve to occur. Labor market problems can improve or deteriorate. Retirement benefits deserve to differ native expectations, either due to the fact that individuals walk not understand the details initially or because the rules readjusted after your initial expectations to be formed.15

Anderson et al. (1986) compared the planned and also actual retirement dates of almost 1,600 male employees in the RHS and found that the majority (about 60%) left work-related within a year of your predicted date. Much more retired earlier than they had planned rather than later, and the proportion together expected increased with the person"s period at the moment of the prediction. An ext importantly, transforms in plans were correlated with transforms in the environment, in particular, with the unanticipated rises in genuine Social security benefits in the so late 1960s and also early 1970s, with alters in individual health and wellness status, and also with transforms in local labor market conditions. Rises in Social defense wealth and health destruction increased the probability of retiring previously than planned and decreased the likelihood of retiring later; an increase in neighborhood unemployment prices did simply the opposite. This research mirrors that to plan do change and that models based on assumptions of certainty will certainly miss component of the story.

Much that the most current and most sophisticated research top top retirement concentrates specifically on issues of uncertainty. Rust (1989), Stock and also Wise (1990), Berkovec and also Stern (1991), and also Lumsdaine et al. (1992) have emerged models in which individuals recalculate your optimal actions each time period, using new information around the present and also their current ideal predictions around the future. The computational needs of several of these models room extreme, so they are usually streamlined in other ways. Because that example, in Rust"s stochastic dynamic programming model, which allows individuals to optimize over period of retirement and also future usage simultaneously, he has actually no pension arrangement incentives and also assumes that unobserved individual factors, such as health and also work-leisure preferences, are uncorrelated over time—an unlikely prospect.

What provides these models exciting is the they perform not assume that workers understand their future wage rates and retirement benefits v certainty, and they permit comparisons of current retirement through retirement at all future dates. In the Stock and Wise (1990) model, for example, a worker decides whether to retire indigenous the firm this particular day by forecasting future wages and also retirement benefits, and then estimating the present discounted value of complete compensation (earnings plus pension and also Social defense accruals) linked with each potential departure day in the future. If any future date looks better, offered his labor-leisure preferences, he continues to work. As soon as he leaves, the cannot go back to the firm. By proceeding to work, the individual retains the alternative of leaving later, in ~ a much more advantageous age. This is the "option value" the work.

After an additional year top top the job, the worker has an ext information about the future, based upon his really earnings during that year and also any other relevant understanding he has acquired. He need to then make one more retirement decision, again comparing instant retirement through retirement in all subsequent years. The forecast of future problems will be various from what they were a year ago, since of the new information. Critical to these models are assumptions around how expectations are formed and also how sensitive they are to new information, both of i beg your pardon are difficult to model.

The Stock and also Wise results are regular with the ahead literature. Pension incentives are really important. Utilizing personnel data indigenous a huge Fortune 500 firm, they find that discontinuities in really retirement prices correspond closely with the incentives the the pension plan, and also predict that transforms in the pension arrangement (such as a hold-up in the early on retirement period or a switch from defined advantage to characterized contribution) would have actually dramatic results on retirement patterns—impacts much bigger than those guess in other records for Social security reform.

Berkovec and Stern (1991) propose a lot more complicated dynamic programming model, in which employees choose among four states—remaining on the present job, switching to a new full-time or a brand-new part-time job, or leaving the job force. Once retired, the separation, personal, instance can pick to stay retired, or have the right to accept a brand-new full-time or a brand-new part-time job. These choices are made every period, based upon current and expected wages, pensions, and also preferences because that leisure. Due to the fact that the version does not encompass Social Security, your predictions miss crucial discontinuities in retirement habits at ages 62 and 65. Nonetheless, they report the their dynamic design outperforms an analogous static model and urge that design dynamics be consisted of explicitly in the estimation procedure.

Lumsdaine et al. (1992) focus directly on the issue of design complexity and also predictive validity. Closer approximation come individual behavior often requires boost in the complexity of the model. At part point, however, the intricacy may exceed the really decision-making procedures at work, and predictive power may decline. In addition, computational burdens linked with intricacy may require other simplifications in the design that mitigate its usefulness.

Lumsdaine et al. Compare the out-of-sample predictive power of three models of boosting complexity—a traditional probit model, an option value model such as that the Stock and Wise (1990), and a dynamic programming design like that of Berkovec and Stern (1991). They report the the latter two predict subsequent retirement actions of a sample of workers from a single firm about equally, however that both significantly outperform the simpler, less forward feather probit model. This suggests that some boosts in model intricacy are worthwhile, yet that others may not be.
