The experience of sexual intercourse for the first time is a significant life event, and influenced by a range of individual, cultural and societal factors. Age of first sexual initiation is a major area of policy and research focus, as the circumstances of first sex (e.g. whether contraception...

Adolescence and young adulthood are critical periods in the development of healthy sexual health and relationships, as patterns of behaviour that develop during these life stages shape outcomes throughout the life course. Recent rises in notifications of certain sexually transmitted infections...

Using a large-scale incentivized trust game experiment conducted across all 27 EU member states, we find that sexual minorities exhibit greater prosocial behaviour toward another vulnerable group but not toward an unknown counterpart, compared to heterosexual individuals. The observed effects...

We propose a unified economic model of sexual exchanges that treats both unpaid and paid sex as outcomes of individual time allocation decisions. Departing from existing literature that separates sex into marital relations or specialized markets, the model incorporates relational skills, gender...

We develop a rational choice model of sexual exchange that unifies marriage and paid sex, explaining two key facts: the gendered segregation of sex markets and the decline in sexual activity and fertility. Individuals choose whether to engage in paid or unpaid sex based on income, human capital,...

In genetics, heterosis describes how crossbreeding produces offspring with greater fitness than their parents. We propose a socioeconomic heterosis hypothesis: does genetic diversity at the individual level benefit economic success? Using UK Biobank data (N=488,152), we find that people with...

We study the effect of having an older sister on the likelihood that girls in sub-Saharan Africa marry before reaching adulthood. Relying on the randomness of the firstborn sibling's sex, we show that having an older sister (as opposed to an older brother) reduces the likelihood of marrying...

We examine whether financial incentives affect fertility and family planning. We use a reform reducing child benefits paid to larger families together with Danish longitudinal register data on the universe of legal abortions and birth control pill purchases to address this question. We find that...

The composition and quality of the child care workforce may be uniquely sensitive to changes in the complementarities between home production and market work. This paper examines whether the expansion of oral contraceptives and abortion access throughout the 1960's and 1970's influenced the...

We examine the multigenerational impacts of legalized abortion in the United States by analyzing how early-life exposure to this policy shift affects birth outcomes in the next generation. Using event study and two-way fixed effects models, we link maternal early-life exposure to legal abortion...

In genetics, heterosis refers to the phenomenon where crossbreeding within a species produces offspring with greater genetic fitness and superior phenotypic characteristics compared to their parents. We propose a novel socioeconomic heterosis hypothesis and examine whether genetic diversity at...

This study investigates the association between childhood parenting styles and the emergence of risk-taking behaviors in young adulthood, a critical life course transition. Utilizing data on risk-taking behaviors among college students, alongside variables reflecting parent-child relationships...

This study examines whether sexual appeals, specifically nudity (body coverage) and model gender, shape consumer responses to advertising. Guided by the Elaboration Likelihood Model, we test whether these factors operate as peripheral cues when argument strength is minimal (fragrance...

We experimentally evaluate a novel approach to IPV prevention that harnesses social media to recruit and engage men in a virtual support group delivered by trained male facilitators via WhatsApp. The program succeeded in recruiting men at high risk of committing IPV through self-targeting alone:...

This report draws on the Growing Up in Ireland (GUI) study to look at pornography use among over 4,500 young adults at 20 years of age. Pornography use was captured as part of a module of questions on different types of internet use. The rich information provided by the GUI study allows us to...

Hormones are the endocrine system’s messengers and an important coordinating mechanism of the body’s growth, development, and functioning, with often simultaneous effects throughout the body and brain. Echoing calls for more interdisciplinary research bridging the gap between endocrinology...

This guide is structured in three standalone yet complementary and interlinked parts, which cover different topics relevant to SOGIESC in asylum. Cross-cutting elements provides information and guidance that are cross-cutting and relevant to both asylum procedure and reception, including legal...

The threat of both offline and online child sexual abuse in the EU grows year by year, affecting 1.5 million children in the EU in 2022 alone. While progress has been made to better protect children online, existing criminal law rules on child sexual abuse and sexual exploitation are no longer...

This report presents the findings of a study launched following Russia's war of aggression against Ukraine on 24 February 2022, which led to a displacement of an unprecedented scale and forced over 8 million people - mostly women and children - to flee Ukraine and seek refuge and protection...
