Intergenerational effects of shifts in women’s educational distribution in South Korea: Transmission, differential fertility, and assortative mating

This study examines the intergenerational effects of changes in women’s education in South Korea. We define intergenerational effects as changes in the distribution of educational attainment in an offspring generation associated with the changes in a parental generation. Departing from the previous approach in research on social mobility that has focused on intergenerational association, we examine the changes in the distribution of educational attainment across generations. Using a simulation method based on Mare and Maralani’s recursive population renewal model, we examine how intergenerational transmission, assortative mating, and differential fertility influence intergenerational effects. The results point to the following conclusions. First, we find a positive intergenerational effect: improvement in women’s education leads to improvement in daughter’s education. Second, we find that the magnitude of intergenerational effects substantially depends on assortative marriage and differential fertility: assortative mating amplifies and differential fertility dampens the intergenerational effects. Third, intergenerational effects become bigger for the less educated and smaller for the better educated over time, which is a consequence of educational expansion. We compare our results with Mare and Maralani’s original Indonesian study to illustrate how the model of intergenerational effects works in different socioeconomic circumstances.     

“Like Parent, Like Child?”: The intergenerational transmission of nonmarital childbearing

Data from the 2002 National Survey of Family Growth (N = 11,180) are used to examine the intergenerational transmission of nonmarital childbearing for US men and women. Findings suggest that being born to unmarried parents increases the risk of offspring having a nonmarital first birth, net of various confounding characteristics. This intergenerational link appears to particularly operate via parents’ breaking up before offspring are age 14 and offspring’s young age at first sex. While the link across two generations in nonmarital childbearing is not accounted for by parents’ socioeconomic status (measured as fathers’ education), several mediating factors vary by socioeconomic background. Gender and race/ethnicity also moderate the intergenerational transmission of nonmarital childbearing. This research sheds light on the prevalence of, and process by which, nonmarital childbearing is repeated across generations, which has important implications for long-term social stratification and inequality.     

Intergenerational transfer of time and risk preferences

There is a growing interest in individual time and risk preferences. Little is known about how these preferences are formed. It is hypothesised that parents may transmit their preferences to their offspring. This paper examines the correlation in offspring and parental time and risk preferences using data from an annual household survey in Australia (the HILDA survey). Both time and risk preferences are examined and we explored whether the correlation in time and risk preferences varies across the distribution of preferences and across the across the four parent–child dyads (mother/daughter, mother/son, father/daughter, father/son). The results show that there is a significant relationship between parents and their young adult offspring risk and time preference measures. The correlation varies across the distribution of time preferences. The correlation was largest for longer planning horizons. Risk averse parents are more likely to have risk averse children. Except for the father/daughter dyad risk seeking parents are more likely to have risk seeking offspring. Some gender differences were found. The association in parental and offspring time preference was larger for mothers than fathers. Daughters are more likely to be influenced by their mother’s risk preferences, however, sons are equally influenced by both parents. The results of this study suggest that the transmission in preferences is more nuanced than previously thought and parental gender may be important.     

Intergenerational Interaction Through Reminiscence Processes

Abstract

Introduction: The interest in intergenerational programmes is increasing. However, there is a need for evaluation and the development of a theoretical framework to explain the mechanism of changes in attitudes of participants which is the purpose of this paper.

Method: From July to December 2002 an intergenerational intervention was conducted with 111 students and 32 elders, who shared their life stories during class time. A Focus group technique was used to evaluate the programme and a theoretical framework was developed to explain the mechanism of changes in attitudes of adolescents towards elders and the attitudes of elders towards adolescents.

Results: The results showed that stereotypes and prejudice exist, from young people towards elders and from elders towards young ones. The theoretical framework developed showed why and how participants changed their views towards each other in an intergenerational programme using reminiscence processes as a means of interaction.

Conclusion: Although the study had some limitations, it was valuable in showing that older people had some negative images of adolescents. It also showed why and how participants changed their view towards each other.     

Reply to comment on “Why do women interact with their parents more often than men? The demonstration effect vs. the biological effect”

In this research note, I argue that none of the claimed empirical evidence of the demonstration effect is causal. The demonstration effect is one of many unobserved motives behind intergenerational interactions. It is extremely difficult to single out the demonstration motive from these unobserved motives. In the real world, it remains a challenge to prove the demonstration effect.     

Bridges Together Creates & Shares Monthly Intergenerational Resources

This article discusses the recognized need for training to support intergenerational engagement. Bridges Together is leading the way in doing so amongst a variety of audiences including teachers, program directors in aging, librarians, mentors, grandparents and more. To establish a network for these audiences to learn, share, and connect; Bridges Together has recently launched a Membership Program so that monthly content can be distributed and individuals can be brought together to network. All of our collaboration aids in intergenerational engagement which is becoming a top priority and an approach to problem-solving within communities, schools, corporations, and families around the world.     

Using intergenerational relationship teaching strategies in a college-level online gerontology course

Society members educated in gerontology are needed to care for older adults in the United States. Young people may have misconceptions and lack of awareness about aging and older adults, which may influence choosing jobs working with elders. However, research has shown that on-ground courses using intergenerational relationships as a teaching strategy have proved to be effective in changing the views of students. This article reports on the experiences of college-level students in an online gerontology course that used an intergenerational relationship teaching strategy. Through journal entries and discussion board postings, students shared new understandings about aging, elders, and themselves. Data were analyzed using narrative inquiry and the threedimensional (3D) inquiry space. Findings showed students’ views could be changed through intergenerational relationships with reflection in an online course.     

The role of intergenerational transfers,land, and education in fertility transition in rural Kenya: the case of Nyeri district

This qualitative study reveals how population pressures, land availability, inheritance norms, and educational opportunities intertwine to influence fertility decline in rural Kenya. Focus group discussions with men and women whose childbearing occurred both before and after the onset of rapid, unexpected fertility transition in Nyeri, Kenya allowed individuals who actually participated in, or witnessed, the fertility transition to “voice” their perceptions as to the mechanisms underlying the transition. Findings suggest that, since land inheritance is a cultural norm, land scarcity and diminishing farm size often influence fertility decision-making and behavior via preferences for fewer children. Further, education does not appear to be the driving cause of fertility behavior change, but rather is adopted as a substitute for land inheritance when land resources are scarce. These findings have implications for our understanding of fertility behavior as well as for improving predictions of fertility transition in other rural sub-Saharan African contexts.     

Extracting the causal component from the intergenerational correlation in unemployment

This paper examines the intergenerational correlation in unemployment in Norway and discusses and estimates two approaches for extracting the causal component: sibling differences and the use of parental unemployment occurring after the child’s outcome as control for the unobserved family heterogeneity. Confirming existing evidence, I find a substantial intergenerational correlation in unemployment. Almost half of this is due to observed family heterogeneity. The causal effect is found to be statistically insignificant by both identification strategies, but while the estimated effect is negative on the sample made for the sibling-difference approach, this finding is not replicated on a less selective sample.
