Trends in Economic Homogamy: Changes in Assortative Mating or the Division of Labor in Marriage?

The growing economic resemblance of spouses has contributed to rising inequality by increasing the number of couples in which there are two high- or two low-earning partners. The dominant explanation for this trend is increased assortative mating. Previous research has primarily relied on cross-sectional data and thus has been unable to disentangle changes in assortative mating from changes in the division of spouses’ paid labor—a potentially key mechanism given the dramatic rise in wives’ labor supply. We use data from the Panel Study of Income Dynamics (PSID) to decompose the increase in the correlation between spouses’ earnings and its contribution to inequality between 1970 and 2013 into parts due to (a) changes in assortative mating, and (b) changes in the division of paid labor. Contrary to what has often been assumed, the rise of economic homogamy and its contribution to inequality is largely attributable to changes in the division of paid labor rather than changes in sorting on earnings or earnings potential. Our findings indicate that the rise of economic homogamy cannot be explained by hypotheses centered on meeting and matching opportunities, and they show where in this process inequality is generated and where it is not.     

Educational Assortative Mating and Income Inequality in Denmark

Many writers have expressed a concern that growing educational assortative mating will lead to greater inequality between households in their earnings or income. In this article, we examine the relationship between educational assortative mating and income inequality in Denmark between 1987 and 2006. Denmark is widely known for its low level of income inequality, but the Danish case provides a good test of the relationship between educational assortative mating and inequality because although income inequality increased over the period we consider, educational homogamy declined. Using register data on the exact incomes of the whole population, we find that change in assortative mating increased income inequality but that these changes were driven by changes in the educational distributions of men and women rather than in the propensity for people to choose a partner with a given level of education.     

Educational Homogamy and Gender-Specific Earnings: Sweden, 1990–2009

Several studies have shown strong educational homogamy in most Western societies, although the trends over time differ across countries. In this article, we study the connection between educational assortative mating and gender-specific earnings in a sample containing the entire Swedish population born 1960–1974; we follow this sample from 1990 to 2009. Our empirical strategy exploits a longitudinal design, using distributed fixed-effects models capturing the impact of partner education on postmarital earnings, relating it to the income development before union formation. We find that being partnered with someone with more education (hypergamy) is associated with higher earnings, while partnering someone with less education (hypogamy) is associated with lower earnings. However, most of these differences in earnings emerge prior to the time of marriage, implying that the effect is explained by marital selection processes rather than by partner education affecting earnings. The exception is hypogamy among the highly educated, for which there are strong indications that in comparison with homogamy and hypergamy, earnings grow slower after union formation.     

The Gender‐Gap Reversal in Education and Its Effect on Union Formation: The End of Hypergamy?

Newly released census microdata reveal the nearly worldwide and substantial decline in educational hypergamy (women marrying men with higher educational attainment) across 56 countries from the 1970s to the 2000s. We examine the extent to which the observed decrease in hypergamy is connected to the worldwide rise in female educational attainment. Our results show that educational hypergamy is an enduring form of gender inequality in union formation across the countries examined but that it has been decreasing over the last few decades and in some countries has reversed in recent years. Overall, we find a strong association between hypergamy and gender differences in educational attainment. Societies in which the female educational advantage is greater tend to have lower levels of educational hypergamy. There is a tendency toward a joint increase in women's educational levels and a decrease in educational hypergamy. This article underlines the influence of women's educational opportunities on the increase in gender symmetry in assortative mating, which leads us to predict the end of educational hypergamy.     

Marital Sorting and Parental Wealth

The extent of marital sorting by socioeconomic background has implications for the intergenerational transmission of inequality, the role of marriage as a mechanism for social mobility, and the extent of cross-group interactions within a society. However, studies of assortative mating have disproportionately focused on spouses’ education, rather than their social origins. Using data from the Panel Study of Income Dynamics (PSID), and exploiting the unique genealogical design of the data set, we study the degree to which spouses sort on the basis of parental wealth. We find that the estimated correlation in parental wealth among married spouses, after controlling for race and age, is about .4. Importantly, we show that controlling for spousal education explains only one-quarter of sorting based on parental wealth. We show that our results are robust to accounting for measurement error in spousal reports of parental wealth and for selection into and out of marriage.     

The Proximate Determinants of Educational Homogamy: The Effects of First Marriage,Marital Dissolution,Remarriage, and Educational Upgrading

This paper adapts the population balancing equation to develop a framework for studying the proximate determinants of educational homogamy. Using data from the National Longitudinal Survey of Youth on a cohort of women born between 1957 and 1964, we decompose the odds of homogamy in prevailing marriages into four proximate determinants: (1) first marriages, (2) first and later marital dissolutions, (3) remarriages, and (4) educational attainment after marriage. The odds of homogamy among new first marriages are lower than among prevailing marriages, but not because of selective marital dissolution, remarriage, and educational attainment after marriage, as has been speculated. Prevailing marriages are more likely to be educationally homogamous than new first marriages because of the accumulation of homogamous first marriages in the stock of marriages. First marriages overwhelmingly account for the odds of homogamy in prevailing marriages in this cohort. Marital dissolutions, remarriages, and educational upgrades after marriage have relatively small and offsetting effects. Our results suggest that, despite the high prevalence of divorce, remarriage, and continued schooling after marriage in the United States, the key to understanding trends in educational homogamy lies primarily in variation in assortative mating into first marriage.

An empirical analysis of the matching patterns of same-sex and opposite-sex couples

We used 1990 Census data to compare the matching behaviors of four types of cohabiting couples: same-sex male couples, same-sex female couples, opposite-sex unmarried couples, and married couples. In general, we found evidence of positive assortative mating for all traits and across all types of couples. The positive assortative mating, however, is stronger for non-labor-market traits (e.g., age, education) than for labor-market traits (e.g., hourly earnings). Further, members of married couples are more alike with respect to most characteristics than are members of opposite-sex cohabiting couples, and members of opposite-sex cohabiting couples are more alike than are members of same-sex couples.     

A Cross-National Analysis of Lifespan Inequality, 1950–2015: Examining the Distribution of Mortality Within Countries

Cross-national health research devotes considerable attention to lifespan and survival rate disparities that are found between countries. However, the distribution of mortality across the world is shaped mostly by what happens within countries. We address this striking gap in the literature by modeling length-of-life inequality for individual nation-states. We use life tables from the United Nation’s (2015) World Population Prospects to estimate inequality levels for 200 countries across 13 waves between 1950 and 2015. We find that lifespan inequality is steadily declining across the world, but that each country’s level of inequality, and the rate at which it declines, vary considerably. Our models account for more than 90% of the longitudinal and cross-sectional variation in country-level lifespan inequality during the 1990–2015 period. Maternal mortality is the strongest predictor in our model, while disease prevalence, access to safe water, and health interventions figure prominently, as well. Gross domestic product per capita shows the expected curvilinear association with lifespan inequality, while primary education (both overall enrollment and gender equity in enrollment), external debt, and migration also play critical roles in shaping health outcomes. By contrast, the distribution of political and economic resources (i.e., democracy and income inequality) is less important.

     

Earnings inequality and subnational political economy in the United States, 1970–2000

Previous studies of rising inequality in the United States have overlooked the potential role of subnational political economic variation as an institution that shapes earnings restructuring. This paper uses hierarchical linear models to examine how state right-to-work laws contribute to growth in inequality in 80 metropolitan labor markets from 1970 to 2000. Contrary to conventional expectations, labor markets in states with right-to-work laws experience relatively mild growth in earnings inequality, and are less unequal by 2000 than non-RTW labor markets. The trend cannot be fully explained by union density, job growth, uneven development or variation in racial inequality. The findings contribute to a distinctly sociological perspective on rising inequality that considers how social, institutional and economic factors interact at the local and state levels to shape earnings.     

The Educational Gradient in Marriage: A Comparison of 25 European Countries

Previous research has suggested that a new marriage gradient has emerged in the United States, with marriage becoming increasingly the privilege of the better-educated. This article examines whether this is true for Europe and explores differences in the marriage gradient among 25 European countries, using multilevel models. The focus is on the chances of living in a marital (or cohabiting) union during midlife (ages 40–49). Multilevel analyses show that the direction and strength of the gradient depend on the societal context. In countries where gender roles are traditional, better-educated women are less likely to be married than less-educated women; in gender-egalitarian countries, better-educated women are more likely to be married. For men, the educational effect on marriage is absent in traditional countries but becomes positive as gender roles become more equal. Inequality in a society also modifies the gradient: if the degree of economic inequality between educational groups in a society is strong, better-educated men are more likely to be married than less-educated men. In general, the results suggest that there may be an accumulation of social and economic disadvantages for the less well educated in more-developed countries.     

From Privilege to Prevalence: Contextual Effects of Women’s Schooling on African Marital Timing

In Africa and elsewhere, educated women tend to marry later than their less-educated peers. Beyond being an attribute of individual women, education is also an aggregate phenomenon: the social meaning of a woman’s educational attainment depends on the educational attainments of her age-mates. Using data from 30 countries and 246 birth cohorts across sub-Saharan Africa, we investigate the impact of educational context (the percentage of women in a country cohort who ever attended school) on the relationship between a woman’s educational attainment and her marital timing. In contexts where access to education is prevalent, the marital timing of uneducated and highly educated women is more similar than in contexts where attending school is limited to a privileged minority. This across-country convergence is driven by uneducated women marrying later in high-education contexts, especially through lower rates of very early marriages. However, within countries over time, the marital ages of women from different educational groups tend to diverge as educational access expands. This within-country divergence is most often driven by later marriage among highly educated women, although divergence in some countries is driven by earlier marriage among women who never attended school.     

The intergenerational transmission of divorce in cross-national perspective: Results from the Fertility and Family Surveys

We used data on women's first marriages from the Fertility and Family Surveys to analyse the intergenerational transmission of divorce across 18 countries and to seek explanations in macro-level characteristics for the cross-national variation. Our results show that women whose parents divorced have a significantly higher risk of divorce in 17 countries. There is some cross-national variation. When compared with the USA, the association is stronger in six countries. This variation is negatively associated with the proportion of women in each cohort who experienced the divorce of their parents and with the national level of women's participation in the labour force during childhood. We conclude that differences in the contexts in which children of divorce learn marital and interpersonal behaviour affect the strength of the intergenerational transmission of divorce.     

The Decomposition of Economic Outcomes as a Result of Changes in Brazil’s Male Age–Education Structure

In Brazil, the age and education compositions of the male labor force is changing with great regional variation. Based on Demographic Census microdata, results indicate that cohort size has a negative impact on earnings, but this effect is decreasing over time. In this study we consider the impact on earnings by age and education, as well as estimated income inequality reduction and racial differentials. Fertility decline and improve regarding educational attainment had a significant influence on the decline of income inequality in the country. Moreover, the non-white population has been experiencing less success in relation to educational achievement, compared to the white population.     

夫妻教育匹配对男性平等分担家务的影响

利用2000年和2010年中国妇女社会地位调查数据,考察了21世纪最初十年间中国婚姻家庭的家务分工特征及其变化,着重检验了夫妻教育匹配对家务分工平等化的影响.研究发现,夫妻平等分担家务的现象近年来呈缓慢的上升趋势,2010年全国接近两成的已婚夫妇相对平等地分担家务.夫高妻低的教育匹配模式不利于推动家务分工平等化以及改变"女主内"的分工模式;与之相对,夫妻教育相同和夫低妻高的教育匹配模式在不同程度上推动着男性平等分担家务.文章认为,夫妻平等分担家务代表了现代社会经济和性别平等文化背景下家务分工演变的方向.实现这一转变,女性自身教育水平的相对提高以及教育匹配现象的演化扮演着极为重要的角色;而营造良好的社会舆论环境与完善社会服务体系,则是家务分工平等化的重要社会保障.

The Educational Homogamy Gap Between Married and Cohabiting Couples in Latin America

The explosive expansion of non-marital cohabitation in Latin America since the 1970s has led to the narrowing of the gap in educational homogamy between married and cohabiting couples (what we call “homogamy gap”) as shown by our analysis of 29 census samples encompassing eight countries: Argentina, Brazil, Chile, Colombia, Costa Rica, Ecuador, Mexico, and Panama (N = 2,295,160 young couples). Most research on the homogamy gap is limited to a single decade and a small group of developed countries (the United States, Canada, and Europe). We take a historical and cross-national perspective and expand the research to a range of developing countries, where since early colonial times, traditional forms of cohabitation among the poor, uneducated sectors of society have coexisted with marriage, although to widely varying degrees from country to country. In recent decades, cohabitation is emerging in all sectors of society. We find that among married couples, educational homogamy continues to be higher than for those who cohabit, but in recent decades, the difference has narrowed substantially in all countries. We argue that assortative mating between cohabiting and married couples tends to be similar when the contexts in which they are formed are also increasingly similar.     

The Trade-off Between Poverty Reduction and Carbon Emissions,and the Role of Economic Growth and Inequality: An Empirical Cross-Country Analysis Using a Novel Indicator

Is it possible for countries to eradicate poverty while also meeting environmental goals? Despite the passage of international agreements calling for these issues to be addressed simultaneously, little is known about the direct relationship between them. This study addresses this gap by proposing a new and composite indicator that integrates measures for both poverty and environmental outcomes (carbon emissions) into a single variable, the carbon intensity of poverty reduction (CIPR). This variable defines the trade-off between the proportional changes of emissions per capita and of the share of the population above the poverty line. In parallel an analytic framework is developed to formulate propositions concerning the possible effects of growth and inequality on the CIPR. The propositions are tested empirically using data from 135 countries across a 30-year time period (1981–2012). The findings confirm that the carbon intensity of poverty reduction is heterogeneous across countries. This heterogeneity is partly explained by economic growth, which is found to have a negative effect on the CIPR up to a certain income level, defined here as a “turning point”. Above that turning point, economic growth increases the CIPR. By contrast, inequality reduction is shown to have a significant negative effect on the CIPR. This study contributes to the literature on sustainable development by analytically and quantitatively linking its three dimensions (social, economic and environmental) and by employing a composite indicator that directly measures the trade-off between poverty reduction and emission levels across countries.
