    Industry Competition and Total Factor Productivity Growth

    This paper analyzes the impact of changes in the competitive market structure on an industry's total factor productivity (TFP) growth. The impact of horizontal mergers on TFP growth is of particular interest. The number of proposed horizontal mergers among U.S. firms totaled 28,818 from 1996 to 2005, while the number of U.S. Department of Justice investigations of proposed mergers totaled 1,303 during the same time period. The impact of mergers upon total factor productivity growth is rightly a topic for consideration. Merger participants routinely claim that mergers will result in welfare improving efficiency gains. If true, these gains should translate into increased TFP growth. This paper estimates this effect and others after presenting a model of TFP growth as a function of changes in the competitive market structure of an industry, changes in production diversification measured at the establishment level, and changes in output per establishment and the number of establishments. Mergers are found to have a positive impact upon TFP growth, accounting for 0.36 percentage points of total factor productivity growth between census years.Productivity Growth, Mergers, Competition

    An Update on Bridge Jobs: The HRS War Babies

    Are today’s youngest retirees following in the footsteps of their older peers with respect to gradual retirement? Recent evidence from the Health and Retirement Study (HRS) suggests that most older Americans with full-time career jobs later in life transitioned to another job prior to complete labor force withdrawal. This paper explores the retirement patterns of a younger cohort of individuals from the HRS known as the “War Babies.” These survey respondents were born between 1942 and 1947 and were 57 to 62 years of age at the time of their fourth bi-annual HRS interview in 2004. We compare the War Babies to an older cohort of HRS respondents and find that, for the most part, the War Babies have followed the gradual-retirement trends of their slightly older predecessors. Traditional one-time, permanent retirements appear to be fading, a sign that the impact of changes in the retirement income landscape since the 1980s continues to unfold.Economics of Aging, Partial Retirement, Gradual Retirement

    A Micro-level Analysis of Recent Increases in Labor Force Participation among Older Workers

    Aggregate data reveal a sizable increase in labor force participation rates since 2000 among workers on the cusp of retirement, reverting back to levels for older men not seen since the 1970s. These aggregate numbers are useful in that they document overall trends, but they lack the ability to identify the reasons behind workers’ decisions. The Health and Retirement Study (HRS) spans the last dozen years from 1992 to 2004, includes two cohorts of retirees, and provides micro-level data regarding these recent trends. Moreover, the HRS contains information on older Americans and the types of jobs they are taking (full-time versus part-time, self-employed versus wage-and-salary, low-paying versus high-paying, blue collar versus white collar, etc.). This study capitalizes on the richness of the HRS data and explores labor force determinants and outcomes of older Americans, with an emphasis on retirees' choices in recent years. We present a cross-sectional and longitudinal description of the financial, health, and employment situation of older Americans. We then explore retirement determinants using a multinomial approach to model gradual retirement and a two-step approach to model the work-leisure and hours intensity decisions of older workers. Evidence suggests that the majority of older Americans retire gradually, in stages, and that younger retirees continue to respond to financial incentives just as their predecessors did. In addition, recent macro-level changes appear to have blurred the distinction between younger and middle-aged retirees.Economics of Aging, Partial Retirement, Gradual Retirement

    The Role of Re-entry in the Retirement Process

    To what extent do older Americans re-enter the labor force after an initial exit and what drives these “unretirement” decisions? Retirement for most older Americans with full-time career jobs is not a one-time, permanent event. Labor force exit is more likely to be a process. Prior studies have found that between one half and two thirds of career workers take at least one other job before exiting from the labor force completely. The transitional nature of retirement may be even more pronounced when considering the impact of re-entry. This paper examines the extent to which older Americans with career jobs re-entered the labor force. The analysis is based on data from the Health and Retirement Study (HRS), an ongoing, longitudinal survey of older Americans that began in 1992. We examined the retirement patterns of a subset of 5,617 HRS respondents who were on a full-time career job at the time of the first interview. Logistic regression was used to explore determinants of re-entry among those who initially exited the labor force. We found that approximately 15 percent of older Americans with career jobs returned to the labor force after initially exiting. Respondents were more likely to re-enter if they were younger, were in better health, or had a defined-contribution pension plan. This research provides empirical evidence of how older Americans are utilizing bridge jobs as they transition from career employment, and that re-entry may be an important part of the work experience of older Americans.Economics of Aging, Partial Retirement, Bridge Jobs, Gradual Retirement

    Self-Employment Transitions among Older American Workers with Career Jobs

    What role does self-employment play in the retirement process? Older Americans are staying in the labor force longer than prior trends would have predicted and many change jobs later in life. These job transitions are often within the same occupation or across occupations within wage-and-salary employment. The transition can also be out of wage-and-salary work and into self employment. Indeed, national statistics show that self employment becomes more prevalent with age, partly because self employment provides older workers with opportunities not found in traditional wage-and-salary jobs, such as flexibility in hours worked and independence. This paper analyzes transitions into and out of self employment among older workers who have had career jobs. We utilize the Health and Retirement Study, a nationally-representative dataset of older Americans, to investigate the prevalence of self employment among older workers who made a job transition later in life and to explore the factors that determine the choice of wage-and-salary employment or self employment. We find that post-career transitions into and out of self employment are common and that health status, career occupation, and financial variables are important determinants of these transitions. As older Americans and the country as a whole face financial strains in retirement income in the years ahead, self employment may be a vital part of the pro-work solution.Retirement, Retirement Transitions, Self Employment

    Aggregate data reveal a sizable increase in labor force participation rates since 2000 among American workers on the cusp of retirement, reverting back to levels for older men not seen since the 1970s. While these aggregate numbers are useful in that they document overall trends, they do not elucidate the reasons behind workers’ decisions. The Health and Retirement Study (HRS), a nationally-representative, longitudinal survey of older Americans that spans 1992 to 2004, provides micro-level data regarding these retirement trends. Moreover, the HRS contains detailed information about the types of jobs older Americans are taking (e.g., full-time versus part-time, self-employed versus wage-and-salary, low-paying versus high-paying, blue collar versus white collar). This study capitalizes on the richness of the HRS data and explores labor force determinants and outcomes of older Americans, with an emphasis on retirees' choices in recent years. We present a cross-sectional and longitudinal description of the financial, health, and employment situation of older Americans. We then explore retirement determinants using multinomial logistic regression to model gradual retirement and logistic and OLS regression to model the work-leisure (whether to work) and hours intensity (how much to work) decisions of older workers. Evidence suggests that the majority of older Americans retire gradually, in stages, and that younger retirees continue to respond to financial incentives just as their predecessors did. In addition, the retirement decisions of younger and middle-aged retirees appear similar in the face of macro-level changes in the early part of this decade.
