Parental Separation and Children's Educational Attainment: A Siblings Analysis on Swedish Register Data

This article analyzes whether the commonly found negative relationship between parental separation in childhood and educational outcomes is causal or mainly due to selection. We use data on about 100,000 Swedish full biological siblings, born in 1948-63, and perform cross-section and sibling-difference estimations. Outcomes are measured as educational attainment in 1996. Our cross-section analysis show the expected negative and significant relationship, while the relationship is not significant, though precisely estimated, in the sibling-difference analysis. This finding was robust to the sensitivity tests performed and is consistent with selection, rather than causation, being the explanation for the negative relationship.

Partner Choice and Women's Paid Work in Sweden - The Role of Earnings

Recent observations of higher labour -market activity among women with a high-earning spouse and widened household inequality have spurred research interest in earnings homogamy and in effects of own and spouse’s earnings on female labour supply. This article studies trends in earnings homogamy among married and cohabiting parents and in effects of own and spouse’s earnings on mothers’ time in employment and non-employment in Sweden. We analyse, first, correlations between spouses’ earnings and, second, effects of time -varying own and spouse’s earnings on mothers’ transitions between part-time and full-time work, on their exits from and re-entries into employment and on their exits from parental leave over the years 1968-92. We use individual life histories from the 1992 Swedish Family Survey combined with longitudinal information on earnings from the national taxation register. A unique aspect of this data set is that it has very accurate longitudinal earnings information for both married and cohabiting spouses, including former spouses. We find that mothers’ own earnings have a larger and more significant impact on their labour -market transitions than spouse’s earnings and that the impact of the latter has even declined over time.-

Does Marriage Lead to Specialization? An Evaluation of Swedish Trends in Adult Earnings Before and After Marriage

We examine whether marriage leads to specialization in Sweden by implementing a model that differentiates specialization in the household by cohabitation and marriage. Our paper evaluates this model using panel data to analyze trends in earnings before and after marriage between 1985 and 1995 for married and long-term cohabiting Swedish couples with children. To identify the effect of marriage on earnings we use the reform of the widow’s pension system that resulted in a marriage boom in Sweden in 1989 and difference-in-difference estimation. Our results show that most of the male marriage premium can be explained by positive selection whereas the female marriage penalty reflects increased specialization in home production and childcare. The findings suggest that the positive selection of men into marriage translates into the increased specialization of women. We also find evidence that marriage facilitates specialization in the few couples where mothers earn more than fathers, resulting in a marriage premium for women and a marriage penalty for men. Finally, we find that the net effect of marriage on family earnings is zero because the male marriage premium is offset by the female marriage penalty. Our results show that specialization results from the legal arrangement of marriage, not from the living arrangement of the household.Marriage; Marriage premium; Specialization

Does Marriage Matter for Children? Assessing the Impact of Legal Marriage in Sweden

This paper examines whether parental marriage confers educational advantages to children relative to cohabitation. We exploit a dramatic marriage boom in Sweden in late 1989 created by a reform of the Widow’s Pension System that raised the attractiveness of marriage compared to cohabitation to identify the effect of marriage and the effect of selection bias on marriage estimates. Sweden’s rich administrative data sources enable us to identify the children who were affected by parental marriage due to this marriage boom. Our analysis addresses the question of whether marginal marriages created by a policy initiative have an impact on children. Using grade point average at age 16 as the outcome variable, we first show the expected pattern that children with married parents do better than children with cohabiting parents. However, once we control for observable family background and compare the outcomes for children whose parents married due to the reform with those for children whose parents remained unmarried, the differences largely disappear. The results from a sibling difference analysis are consistent with the conclusion that the differentials among children of married and cohabiting parents reflect selection rather than causation.family structure; marriage; child well-being; educational attainment

Time Out for Childcare: Signalling and Earnings Rebound Effects for Men and Women

The wage cost of time out of the labor force for childcare is important in order to understand the functioning of labor markets and for public policy. This paper reviews the literature and identifies several limitations. Using employment records of a large Swedish company over the period 1983-88, we demonstrate an alternative approach for estimating earnings effects and find a year out costs 1.7 percent of earnings for a woman and 5.2 percent for a man. This large effect for men raises questions of signalling costs. For both men and women, earnings‘'rebound'’for time out in the more distant past.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/75622/1/j.1467-9914.1996.tb00102.x.pd

Normo- and hyperandrogenic women with polycystic ovary syndrome exhibit an adverse metabolic profile through life

Objective: To compare the metabolic profiles of normo- and hyperandrogenic women with polycystic ovary syndrome (PCOS) with those of control women at different ages during reproductive life. Design: Case-control study. Setting: Not applicable. Patient(s): In all, 1,550 women with normoandrogenic (n = 686) or hyperandrogenic (n = 842) PCOS and 447 control women were divided into three age groups: 39 years). Interventions(s): None. Main Outcome Measure(s): Body mass index (BMI), waist circumference, blood pressure, glucose, insulin, cholesterol, lipoproteins, triglycerides and high-sensitivity C-reactive protein. Result(s): Both normo- and hyperandrogenic women with PCOS were more obese, especially abdominally. They had increased serum levels of insulin (fasting and in oral glucose tolerance tests), triglycerides, low-density lipoprotein, and total cholesterol, higher blood pressure, and lower high-density lipoprotein levels independently from BMI compared with the control population as early as from young adulthood until menopause. The prevalence of metabolic syndrome was two-to fivefold higher in women with PCOS compared with control women, depending on age and phenotype, and the highest prevalence was observed in hyperandrogenic women with PCOS at late reproductive age. Conclusion(s): When evaluating metabolic risks in women with PCOS, androgenic status, especially abdominal obesity and age, should be taken into account, which would allow tailored management of the syndrome from early adulthood on.

Higher blood pressure in normal weight women with PCOS compared to controls

Objective: Obesity is considered to be the strongest predictive factor for cardio-metabolic risk in women with polycystic ovary syndrome (PCOS). The aim of the study was to compare blood pressure (BP) in normal weight women with PCOS and controls matched for age and BMI. Methods: From a Nordic cross-sectional base of 2615 individuals of Nordic ethnicity, we studied a sub cohort of 793 normal weight women with BMI = 140/90 mmHg was 11.1% (57/ 512) in women with PCOS vs 1.8% (5/281) in controls, P = 35 years the prevalence of BP >= 140/90 mmHg was comparable in women with PCOS and controls (12.7% vs 9.8%, P = 0.6). Using multiple regression analyses, the strongest association with BP was found for age, waist circumference, and total cholesterol in women with PCOS. Conclusions: Normal weight women with PCOS have higher BP than controls. BP and metabolic screening are relevant also in young normal weight women with PCOS.Peer reviewe

Female labour force participation, fertility and public policy in Sweden

This paper analyzes the role of public policy for Sweden's combination of high female labour force participation and high levels of fertility in the late 1980s and early 1990s. We present the central elements in the tax and family policies and use a disaggregated approach to assess their impact on Swedish fertility and female labour force participation. We show that these policies stimulate both fertility and women's paid work by reducing the costs of having children while requiring parents to be employed to collect full benefits. Cet article analyse le rôle des politiques sur le lien entre une forte participation féminine au marché du travail et de hauts niveaux de fécondité en Suède, à la fin des années 1980 et au début des années 1990. Nous présentons d'abord les principaux éléments des politiques fiscales et parentales. Puis nous utilisons une approche désaggrégée pour mettre en évidence leur impact sur la fécondité suédoise et la participation féminine au marché du travail. Nous montrons que ces politiques stimulent à la fois la fécondité et le travail féminin rémunéré en réduisant les coûts en vue d'élever les enfants tout en demandant aux parents d'être actifs pour en recueillir les pleins bénéfices.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/42731/1/10680_2005_Article_BF01797210.pd

Repositioning of the global epicentre of non-optimal cholesterol

High blood cholesterol is typically considered a feature of wealthy western countries(1,2). However, dietary and behavioural determinants of blood cholesterol are changing rapidly throughout the world(3) and countries are using lipid-lowering medications at varying rates. These changes can have distinct effects on the levels of high-density lipoprotein (HDL) cholesterol and non-HDL cholesterol, which have different effects on human health(4,5). However, the trends of HDL and non-HDL cholesterol levels over time have not been previously reported in a global analysis. Here we pooled 1,127 population-based studies that measured blood lipids in 102.6 million individuals aged 18 years and older to estimate trends from 1980 to 2018 in mean total, non-HDL and HDL cholesterol levels for 200 countries. Globally, there was little change in total or non-HDL cholesterol from 1980 to 2018. This was a net effect of increases in low- and middle-income countries, especially in east and southeast Asia, and decreases in high-income western countries, especially those in northwestern Europe, and in central and eastern Europe. As a result, countries with the highest level of non-HDL cholesterol-which is a marker of cardiovascular riskchanged from those in western Europe such as Belgium, Finland, Greenland, Iceland, Norway, Sweden, Switzerland and Malta in 1980 to those in Asia and the Pacific, such as Tokelau, Malaysia, The Philippines and Thailand. In 2017, high non-HDL cholesterol was responsible for an estimated 3.9 million (95% credible interval 3.7 million-4.2 million) worldwide deaths, half of which occurred in east, southeast and south Asia. The global repositioning of lipid-related risk, with non-optimal cholesterol shifting from a distinct feature of high-income countries in northwestern Europe, north America and Australasia to one that affects countries in east and southeast Asia and Oceania should motivate the use of population-based policies and personal interventions to improve nutrition and enhance access to treatment throughout the world.Peer reviewe
