The fortunes of one's birth: Relative cohort size and the youth labor market in the United States

Using two different measures of relative cohort size – one indicating the size and placement of an individual's own birth cohort, and the other, the ratio of young to prime age adults in the United States in that year – it has been possible to isolate strong effects of the population age structure on wages in the United States over the past thirty-three years. These effects have been strong enough that virtually all of the observed change in the experience premium, and a substantial proportion of the changes in the college wage premium, can be explained by the relative cohort size variables alone. Even changes in the amount of within-group variance in wages appear to be largely a function of changing age structure, and absolute wage levels have been strongly affected by these demographic changes, suggesting that population growth can have positive effects on the economy.

Occupational mobility of American women: Compositional and structural changes, 1980–2007

In this paper, I document trends in women's occupational mobility between 1980 and 2007 in the U.S labor market, and link these trends to two distinct sources: compositional and structural changes. In this context, compositional changes refers to the over time trends in the distributions of men and women in the occupational wage hierarchy, while structural changes are the trends in the relative standing of occupations in the wage hierarchy over time. The findings provide empirical evidence for both processes, indicating that the impressive upward occupational mobility of American women is a consequence not only of their increased access to highly paid occupations, but also of the higher wage increments in their typical occupational profiles relative to men's—a structural change not often acknowledged by sociologists.     

Women in the workforce and family structure in Australia

The purpose of this paper is to set out some of the changes that have taken place in the economic status of women in Australia and to discuss the relationship between economic factors and family structure. I look at the position of women in the workforce and examine some of the possible explanations for the increase in female participation. These include the increase in the female wage, demographic changes and changes in the industrial composition of the economy. In a final section, I examine some of the evidence for the effect of economic variables, particularly the wage, on fertility. I would like to thank Bob Gregory, Bruce Chapman, George Fane, Francis Teal and the Journal’s referees for valuable comments on an earlier draft. All responsibility for remaining errors is mine.     

Employment trends ofyoung mothers and the opportunity cost of babies in the United States

The central concept of microeconomic theories of fertility is opportunity cost--the product of wife's employment lost due to childbearing and the value of her employment. This paper presents a model for analyzing opportunity cost using panel data. The average loss of employment attributable to a second- or higher-order birth, calculated at around age 2, is over 400 hours per year. This time cost represents an income loss of about $1050 in 1969 dollars. Time cost is independent of such demographic factors as birth order and age of oldest sibling. Neither does time cost depend on husband's wage rate or wife's education or potential wage rate. This indicates that many microeconomic models of fertility have been seriously misspecified. The paper also compares results from static and dynamic models, explores possible problems due to simultaneity bias, investigates the relationship between changes in employment (including time cost) and initial employment level, and identifies the difficulties of theorizing about opportunity cost.     

Wage differentials due to gender

In this paper, a longitudinal data set covering 5% of all Danish wage earners over a 9-year period is used to shed light on the observed wage differentials due to gender. A human capital model is used to isolate the effects of changes in experience, schooling and unemployment, together with other factors. The model is specified as a fixed effect model that takes into account unobserved factors such as individual skills, the tendency to have an extra job and other factors. Despite the observation from macro statistics that women have had the highest observed increases in wage rates, the models show that this increase is mainly due to an improvement in their background characteristics and that men still receive a higher return to their characteristics. The main difference between genders appears to be that female workers do not, in general, get any return to their experience. The estimates also show negative effects on the wage rate of previous spells of unemployment.Peder J. Pedersen, the labour workshop at the Aarhus School of Business and two unknown referees are thanked for valuable comments. However, only the authors are responsible for any remaining errors.

Fertility waves,aggregate savings and the rate of interest

During the last fifty years there have in many countries been large movements in the growth of labor productivity, real wage rates, the rate of interest, and the household savings ratio. In this paper we use an overlapping generations model to study if demographic shocks, like the baby boom, can generate the kind of movements observed. Simulations show this is indeed the case. We also study the interactions between a pay-as-you-go pension system and demographic disturbances.We are grateful to Laurence Ball, Alex Cukierman and two anonymous referees for helpful comments.     

A Multidimensional Approach in International Comparative Policy Analysis Based on Demographic Projections

The present study adopts a multidimensional approach to classifying countries in international comparative policy analyses. The article builds a data-based typology founded on future demographic projections of the United Nations. Latent class analysis is used to identify various demographic profiles of countries based on fertility rates, net migration rates, and dependency ratios. There is great value in identifying future changes in population composition, as it enables governments to set policy agenda, prioritize needs, and prepare better for what lies ahead. The paper demonstrates the value of such typology to social services, by analyzing the demographic profiles and estimating their implications for future challenges in educational provision. The contributions of the paper to international comparative policy analysis are discussed.     

Occupational segregation and the gender wage gap

The role of occupational segregation in the determination of gender wage differentials is assessed. It is found (1) that occupational segregation plays less of a role in explaining wage differentials than do traditional human capital variables; (2) that earnings profiles generated with data that include a percent female (PF) measure of occupational segregation are not ideal for testing human capital predictions yet nonetheless yield parameters consistent with neoclassical theory; and (3) that lifetime work considerations, such as the degree of one's labor force intermittency, are important in determining both one's occupation and wage. The implications are that government antidiscrimination policies based on outcome measures are in general inefficient. Instead, the government should concentrate on creating incentives for women to participate in the labor market on an equal basis as males.     

The obesity pay gap: gender,body size,and wage inequalities—a longitudinal study of Chinese adults, 1991–2011

Sociocultural values promoting Western body-type ideals have proliferated over the past 20 years. An important question is whether the same obesity wage penalties seen in the United States, such as wage reductions for obese individuals, are emerging in China as ideals of beauty change to reflect Western ones. We hypothesize that Westernisation will exacerbate the impact of body size on wages for years to come, particularly for urban non-manual workers whose workplaces call for extensive interpersonal relations with employers, colleagues, and customers. This study examines the economic outcomes for individuals aged 18–55, focusing on 6600 female and 8488 male participants in the longitudinal 1991–2011 China Health and Nutrition Survey. Linear fixed-effects regression models estimate the net effect of body mass index (BMI) on wages, as well as the marginal effect of BMI on wages, by survey year. All analyses control for demographic backgrounds and household fixed effects, and are stratified by gender. The results show that normal-weight women with non-manual jobs in 2011 made 2.79–2.95 times more than they had in 1991, while overweight women made 2.66–2.76 times more, and obese women made only 2.57–2.63 times more. The results also indicate that women with non-manual jobs have been subject to wage disparities since 2000. Specifically, the wage disparity for heavier women living in urban areas with non-manual jobs increased significantly after 2000, while current male obesity rates may have been propelled by social acceptance of larger body sizes among men, particularly for manual workers living in rural areas.     

中国人口的迁移转变——基于迁移率的考察

经典人口转变理论侧重死亡和生育转变过程的测量、描述和解释,地理学家将迁移转变纳入人口转变框架,以完善人口转变理论。不过与死亡和生育转变研究不同,中国的迁移研究侧重基于对迁移流动人口规模和结构的考察分析,少有采用人口学意义上的迁移率指标的研究。文章利用2010—2015年历次中国综合社会调查的合并数据,通过人口学方法和泊松回归模型,计算和分析了1950—2015年中国人口迁移率趋势及社会经济差异。中国的迁移转变在宏观趋势上与中国的政治经济变迁高度一致。与死亡和生育转变相比,其波折性更强,说明更易受到经济社会政策变化的冲击。同时也观察到逢“0”和逢“5”年份的申报偏好。另外,迁移的社会经济差异明显。男性迁移率高于女性,但是两性差异在不断缩小;乡城迁移和未婚迁移大幅度增长;而越来越多受教育程度较高人群加入迁移,使得受教育程度越高的人群具有越高的迁移率。可以认为基于迁移率的考察揭示了中国迁移转变更具体生动的过程。     

城市工资上涨、劳动力转移与投资拉动增长方式——基于中国地级城市面板数据的分析

改革开放后,中国以高投资率带动了城市经济的高速增长,但随着农村剩余劳动力存量的不断减少,劳动力供给增长开始跟不上高投资带来的劳动力需求的增长,城市经济的发展正面临着工资加速上涨、投资的产出与就业效应不断降低的挑战。文章利用2004～2009年中国地级城市面板数据进行实证分析,结果显示,城市工资上涨对劳动力供给的拉力是递减的,而对劳动力需求的抑制作用却是递增的;劳动力市场均衡的比较静态分析结果显示,投资的工资上涨效应在递增,而投资的产出与就业效应在递减,因此城市工资上涨是必然趋势。此外,工资上涨对外商直接投资有明显抑制作用,在国内外双重压力下,中国继续实行投资拉动的增长方式已不是明智的选择。     

Regional Differences in the Gender Wage Gap in Spain

This study examines regional differences in the gender wage gap in Spain using matched employer–employee microdata, two different econometric decomposition methods and panel data techniques. Our findings suggest that Spain shows a significant regional heterogeneity in the size of the raw gap, roughly comparable to cross-country differences observed in the European context. The results from the decomposition analysis show that although the bulk of the gender wage gap in Spanish regions is due to differences in the endowments of productive characteristics between males and females there is still a substantial part of the gap that remains unexplained. The analysis of the causes behind the variation of both, the raw and the unexplained gender wage gap by region highlights that several economic, institutional and demographic elements identified in previous studies analysing international differences in the gender wage gap are also relevant to explain regional differences in the gender wage gap in Spain.     

中国的家庭结构转变--来自居住方式与人口因素的作用

基于历次人口普查数据,利用SOCSIM微观模拟方法将家庭转变的关键影响因素分解为人口因素和居住方式因素两个方面,并进一步将人口因素分解为人口惯性、生育率、死亡率和结婚率四个层面进行计量分析.结果发现,当前人口变动相对稳定,较小的波动使其在家庭转变中的贡献率相对较小,而居住方式的影响相对较大;对人口因素的进一步分解还发现,人口惯性及生育率水平的作用相对更大,生育率水平、结婚率水平带来的影响与人口因素的总影响方向是一致的,均提高了一人户、一代户、二代户的人口比重,降低了三代及以上户的人口比重.与之相反,死亡率的影响与人口因素的总影响方向是相反的.     

The Effect of Education on the Demographic Dividend

The impact of population structure on economic growth has been studied in recent decades using different methods to estimate the so‐called demographic dividend. Besides, education has been pointed out as a key factor in economic growth. We propose a decomposition of the demographic dividend, into age and education effects. We illustrate the potentialities of the method, deriving an application to Mexico and Spain over the period 1970‐2100. To that end, we estimate the National Transfer Accounts age profiles by schooling level and apply them to recently available population projections stratified by education level. Our results confirm the role of population age structure in the demographic dividend, but also reveal that education attainment can be even more crucial. Moreover, we find that how both age and education effects finally impact on economic growth depends to a great extent on the specific consumption and labor income age profiles in each country.     

Child care demand and labor supply of young mothers over time

This paper uses panel data from the National Longitudinal Survey of Youth (NLSY) to analyze jointly fertility, employment, and child care decisions of young women over time. As these young women age (from 21 to 25 years on average) they become increasingly likely to have young children, to be employed, and to use non-relative forms of child care. A multivariate analysis reveals that rising wage rates and changes in household structure are important determinants of these upward trends. Further analysis reveals a considerable amount of movement each year among states defined by the presence of young children, employment, and child care arrangement. Overall the young women in the NLSY can be characterized as being in a volatile stage of their lives, when many economic and demographic factors are changing. They appear to respond to these changes by altering their labor supply and child care behavior.     

家庭因素对性别工资差异的影响——基于CFPS数据的实证分析

随着职业性别隔离现象不断减少、男女受教育水平和教育收益率的逐步收敛,人力资本、职业和行业分布已经无法解释我国性别工资差异不断扩大的趋势。从家庭出发,考察婚姻、家务劳动分工和子女这些典型的家庭特征因素对性别工资差异的影响,运用2016年CFPS数据,在解决内生性问题的条件下,研究结果表明:婚姻通过增加女性家务劳动时间和子女间接影响女性工资,家务劳动时间和母亲身份对女性工资率具有显著的惩罚效应,女性平均每周承担家务劳动17小时,这导致其周工资率减少34%,子女降低母亲8.5%的周工资率;相对于未婚女性,已婚女性每周多做7小时家务,这降低了她们14%的周工资率。男性则存在婚姻溢价效应。Oaxaca分解也显示,家庭特征,尤其是家务劳动时间,是性别歧视之外导致性别工资差距的主要原因。本文按收入阶层的异质性分析表明,家庭特征可能引起低收入阶层更大的性别工资差异。本文的分析还显示,家务劳动对男性和女性具有门槛效应,且阈值位于10.5小时左右。     

Employment gains and wage declines: The erosion of black women’s relative wages since 1980

Public policy initiatives in the 1950s and 1960s, including Affirmative Action and Equal Employment Opportunity law, helped mitigate explicit discrimination in pay, and the expansion of higher education and training programs have advanced the employment fortunes of many American women. By the early 1980s, some scholars proclaimed near equity in pay between black and white women, particularly among young and highly skilled workers. More recent policy initiatives and labor market conditions have been arguably less progressive for black women’s employment and earnings: through the 1980s, 1990s, and the first half of the 2000s, the wage gap between black and white women widened considerably. Using data from the Current Population Survey Merged Outgoing Rotation Group (CPS-MORG), this article documents the racial wage gap among women in the United States from 1979 to 2005. We investigate how demographic and labor market conditions influence employment and wage inequality among black and white women over the period. Although shifts in labor supply influence the magnitude of the black-white wage gap among women, structural disadvantages faced by black women help explain the growth in the racial wage gap.     

区域经济环境对工资性别差异的影响——基于多层模型的分析途径

本文建立了中国城镇居民工资方程的多层模型,并提出了相应的工资差异分解方法,用于分析区域经济环境对工资性别差异的影响。结果表明,在所有地区劳动力市场中,均存在明显的工资性别差异。虽然地区市场化水平的提高有助于个体工资水平的提升,但却导致工资性别差异的扩大;尽管地区失业率的上升将对个体工资获得产生不利影响,但却导致工资性别差异的缩小。市场化程度越高的地区,工资性别歧视越严重。因此,在市场化进程中,政府在努力发展教育和扩大就业的同时,应致力于实施公平的工资分配制度,将有助于缓解针对女性的工资歧视,进而有助于工资性别差异的缩小。     

The impact of labor market entry conditions on initial job assignment and wages

We estimate the effects of labor market entry conditions on wages for male individuals first entering the Austrian labor market between 1978 and 2000. We find a large negative effect of unfavorable entry conditions on starting wages and a sizable negative long-run effect. Our preferred estimates imply a decrease in starting wages by about 0.9 % and a lifetime loss in wages of about 1.3 % for an increase in the initial local unemployment rate by one percentage point. We show that poor entry conditions are associated with lower quality of a worker’s first employer and that the quality of workers’ first employer explains as much as three-quarters of the observed long-run wage effects resulting from poor entry conditions. Moreover, wage effects are much more persistent for blue-collar workers because some of them appear to be permanently locked in into low-paying jobs/tasks.     

Macroeconomic conditions, institutional factors and demographic structure: What causes welfare caseloads?

Some of the possible determinants of changes observed in welfare caseloads are analysed in this study. The paper attempts to explain variations in welfare caseloads on the basis of four different factors: macroeconomic conditions, interactions with other income maintenance programmes, changes in the programme's parameters and changes in the demographic structure. Different models are tested by applying time series techniques. The data employed are of an administrative nature and cover the whole period that the Madrid programme has been in operation. The results show that the effects of both unemployment and institutional variables are strong and significant. Macroeconomic effects on caseloads could be offset or reinforced by changes in unemployment protection and reforms of the programme's parameters. The significant effects found for the share of lone-parent applicants also show that demographic shifts could shape the trends of welfare rolls regardless of the changes in unemployment or the implementation of institutional reforms.
