Observing many researchers using the same data and hypothesis reveals a hidden universe of uncertainty.

This study explores how researchers' analytical choices affect the reliability of scientific findings. Most discussions of reliability problems in science focus on systematic biases. We broaden the lens to emphasize the idiosyncrasy of conscious and unconscious decisions that researchers make during data analysis.

Wealth in Couples: Introduction to the Special Issue.

The assumption that economic resources are equally shared within households has been found to be untenable for income but is still often upheld for wealth. In this introduction to the special issue "Wealth in Couples", we argue that within-household inequality in wealth is a pertinent and under-researched area that is ripe for development. To this end, we outline the relevance of wealth for demographic research, making the distinction between individual and household wealth.

My Wealth, (Y)Our Life Satisfaction? Sole and Joint Wealth Ownership and Life Satisfaction in Marriage.

Unlabelled: This study examines the money-subjective well-being nexus by studying the link between changes in jointly and solely (i.e. respondents' own and their partner's own) held gross wealth and changes in married individuals' subjective well-being.

Who Opts Out? The Customisation of Marriage in the German Matrimonial Property Regime.

Unlabelled: This study examines the prevalence of marital contracts across marriage cohorts (1990-2019) in Germany. We further investigate the characteristics of spouses who signed a marital contract. Using cross-sectional data from the German Family Panel (pairfam, 2018/19), we employ complementary log-log and multinomial logistic regression models to predict the prevalence and the type of marital contracts.

Gendered employment trajectories and individual wealth at older ages in Eastern and Western Germany.

This study examines the association between employment trajectories and retired men's and women's individual wealth at older ages in the two distinct welfare state contexts of Eastern and Western Germany. Because of the increasing re-marketization of retirement provisions, wealth is becoming increasingly important for retirees' economic well-being. Using data from the German Socio-Economic Panel Study (2002, 2007, 2012 and 2017), we conduct sequence and cluster analyses to identify groups of typical employment trajectories of men and women in Eastern and Western Germany.

Interdependencies in Mothers' and Daughters' Work-Family Life Course Trajectories: Similar but Different?

Women's life courses underwent substantial changes in the family and work domains in the second half of the twentieth century. The associated fundamental changes in opportunity structures and values challenged the importance of families of origin for individual life courses, but two research strands suggest enduring within-family reproduction of women's family behavior and work outcomes. We revisit this issue by studying two complementary types of intergenerational associations in women's combined work-family trajectories.

Fewer Siblings, More Wealth? Sibship Size and Wealth Attainment.

This study examines the association between sibship size and wealth in adulthood. The study draws on resource dilution theory and additionally discusses potentially wealth-enhancing consequences of having siblings. Data from the German Socio-Economic Panel Study (SOEP,  = 3502 individuals) are used to estimate multilevel regression models adjusted for concurrent parental wealth and other important confounders neglected in extant work.

Birth cohort, ageing and gender ideology: Lessons from British panel data.

Individuals' gender attitudes influence their behaviors, and adherence to traditional gender ideology is an important mechanism contributing to the (re)production of gender inequalities. In developed nations, the 'gender revolution' was accompanied by marked societal shifts towards gender-egalitarian attitudes, but these trends have recently stalled. In this paper, we re-examine the role of birth cohort and ageing in influencing gender ideology through the lens of life-course theory and leveraging British panel data.

The distribution of housing wealth in 16 European countries: accounting for institutional differences.

Housing wealth is the largest source of household wealth, but we know little about the distribution of housing wealth and how institutions have shaped this distribution. Subsidies for homeownership, privatisation of social housing and mortgage finance liberalisation are likely to have influenced the distribution of housing wealth in recent decades. To examine their impact, we describe housing wealth inequalities across occupational classes for two birth cohorts aged fifty and older.

Long-term Health Consequences of Adverse Labor Market Conditions at Time of Leaving Education: Evidence from West German Panel Data.

Using longitudinal survey data from the Socio-Economic Panel Study ( N = 3,003 respondents with 22,165 individual-year observations) and exploiting temporal and regional variation in state-level unemployment rates in West Germany, we explore differences in trajectories of individuals' self-rated health over a period of up to 23 years after leaving education under different regional labor market conditions. We find evidence for immediate positive effects of contextual unemployment when leaving education on individuals' health. We find no evidence for generally accelerated or decelerated health deterioration when leaving education in high-unemployment contexts.

The Marriage Wealth Premium Revisited: Gender Disparities and Within-Individual Changes in Personal Wealth in Germany.

This study examines the association between marriage and economic wealth of women and men. Going beyond previous research that focused on household wealth, I examine personal wealth, which allows identifying gender disparities in the association between marriage and wealth. Using unique data from the German Socio-Economic Panel Study (2002, 2007, and 2012), I apply random-effects and fixed-effects regression models to test my expectations.

Intergenerational transmission of homeownership in Europe: revisiting the socialisation hypothesis.

Socialisation towards homeownership during childhood has been proposed as one transmission channel of homeownership across generations in previous literature, but tests of this socialisation hypothesis are scarce. This study presents the yet most rigorous test of the socialisation hypothesis using retrospective life-history data (SHARELIFE, N=19,567 individuals) from 13 European countries. Event history and panel regression models are applied.
