Employer pensions that integrate benefits with Social Security have been the focus of relatively little research. Since changes in Social Security benefit levels and other program characteristics can affect the benefit levels and other features of integrated pension plans, it is important to know who is covered by these plans. This article examines the characteristics of workers covered by integrated pension plans, compared to those with nonintegrated plans and those with no pension coverage. Integrated pension plans are those that explicitly adjust their benefit structure to help compensate for the employer's contributions to the Social Security program. There are two basic integration methods used by defined benefit (DB) plans. The offset method causes a reduction in employer pension benefits by up to half of the Social Security retirement benefit; the excess rate method is characterized by an accrual rate that is lower for earnings below the Social Security taxable maximum than above it. Defined contribution (DC) pension plans can be integrated along the lines of the excess rate method. To date, research on integrated pensions has focused on plan characteristics, as reported to the Bureau of Labor Statistics (BLS) through its Employee Benefits Survey (EBS). This research has examined the prevalence of integration among full-time, private sector workers by industry, firm size, and broad occupational categories. However, because the EBS provides virtually no data on worker characteristics, analyses of the effects of pension integration on retirement benefits have used hypothetical workers, varying according to assumed levels of earnings and job tenure. This kind of analysis is not particularly helpful in examining the potential effects of changes in the Social Security program on workers' pension benefits. However, data on pension integration at the individual level are available, most recently from the Health and Retirement Study (HRS), a nationally representative survey of individuals aged 51-61 in 1992. This dataset provides the basis for the analysis presented here. The following are some of the major findings from this analysis. The incidence of pension integration in the HRS sample is 32 percent of all workers with a pension (14 percent of all workers). The HRS can also identify integrated DC plans, a statistic that is not available from BLS data. The rate of integration for workers with only DC plans is 8 percent. After controlling for other variables, several socio-demographic characteristics are significantly related to the incidence of integration. The probability of having an integrated pension is 4.6 percentage points less for men compared to women. Non-Hispanic blacks are 6.4 percentage points less likely than non-Hispanic whites to have integrated pensions. Union members are 14 percentage points less likely to have integrated pensions, while workers with less than a graduate level education are at least 15 percentage points more likely to have a pension that is integrated. Some earnings and pension characteristics are also significantly correlated with pension integration. Earnings are positively related, with the probability of having an integrated pension increasing by 2 percentage points for an increase of $1,000 in annual pay. An even larger effect comes from earning at or above the Social Security taxable maximum. Workers at or above this income level are 10 percentage points more likely to have an integrated plan, but for those with more than one plan the probability of pension integration goes up by 13 percentage points.
将养老金福利与社会保障相结合的雇主养老金计划,相对而言较少受到研究关注。由于社会保障福利水平的变化以及其他项目特征会影响综合养老金计划的福利水平和其他特征,因此了解哪些人参加了这些计划很重要。本文研究了参加综合养老金计划的工人的特征,并将其与参加非综合计划的工人以及没有养老金覆盖的工人进行了比较。综合养老金计划是那些明确调整其福利结构,以帮助补偿雇主向社会保障计划缴纳的款项的计划。固定收益(DB)计划使用两种基本的整合方法。抵消法会使雇主养老金福利减少,最多可达社会保障退休福利的一半;超额费率法的特点是,对于低于社会保障应税上限的收入,其应计比率低于高于该上限的收入。固定缴款(DC)养老金计划可以按照超额费率法进行整合。迄今为止,关于综合养老金的研究主要集中在计划特征上,这些特征是通过劳工统计局(BLS)的《员工福利调查》(EBS)报告的。这项研究考察了全职私营部门工人中按行业、公司规模和广泛职业类别划分的整合情况。然而,由于EBS几乎没有提供关于工人特征的数据,对养老金整合对退休福利影响的分析使用了假设的工人,这些工人根据假定的收入水平和工作年限而有所不同。这种分析对于研究社会保障计划的变化对工人养老金福利的潜在影响并不是特别有帮助。然而,关于个人层面养老金整合的数据是可用的,最近的数据来自健康与退休研究(HRS),这是一项对1992年年龄在51 - 61岁的个人进行的全国代表性调查。这个数据集为本文所呈现的分析提供了基础。以下是该分析的一些主要发现。在HRS样本中,养老金整合的发生率在所有有养老金的工人中占32%(在所有工人中占14%)。HRS还可以识别综合DC计划,这是BLS数据中没有的统计数据。仅有DC计划的工人的整合率为8%。在控制了其他变量之后,几个社会人口特征与整合发生率显著相关。男性拥有综合养老金的概率比女性低4.6个百分点。非西班牙裔黑人拥有综合养老金的可能性比非西班牙裔白人低6.4个百分点。工会成员拥有综合养老金的可能性低14个百分点,而教育程度低于研究生水平的工人拥有综合养老金的可能性至少高15个百分点。一些收入和养老金特征也与养老金整合显著相关。收入呈正相关,年薪每增加1000美元,拥有综合养老金的概率就增加2个百分点。来自达到或高于社会保障应税上限收入的影响更大。处于或高于此收入水平的工人拥有综合计划的可能性高10个百分点,但对于拥有不止一个计划的人来说,养老金整合的概率上升13个百分点。
