DIAL Policy Brief No. 2 ‘Towards a socially mobile Europe: What can policymakers learn from Dynamics of Inequality Across the Life-course (DIAL) research?’

Authors: ,
Issue: 2021
Themes: , ,

There are a number of key European policy agendas related to social mobility on which the DIAL research can shed light. This policy brief gives an overview of findings from DIAL projects in this area. Key findings: Educational opportunity is the most powerful tool in improving the life chances of those born into disadvantaged families. … Read more

Socioeconomic Background and Gene–Environment Interplay in Social Stratification across the Early Life Course

This study finds that genetic inheritance has more influence than the shared social environment alone in perpetuating social inequalities. However, the importance of genes varies according family environment: genetic influences are stronger among those growing up in the most advantaged families. The researchers studied 6,500 pairs of twins born in Finland between 1975 and 1986. They used … Read more

A decade of research on the genetics of entrepreneurship: a review and view ahead

Authors: , ,
Issue: 2021
Themes:

Studies analyzing the heritability of entrepreneurship indicate that explanations for why people engage in entrepreneurship that ignore genes are incomplete. However, despite promises that were solidly backed up with ex ante power calculations, attempts to identify specific genetic variants underlying the heritable variation in entrepreneurship have until now been unsuccessful. We describe the methodological issues … Read more

Stop Meta-Analyzing, Start Instrumenting: Maximizing the Predictive Power of Polygenic Scores

Polygenic scores have become the workhorse for empirical analyses in social-science genetics. Because a polygenic score is constructed using the results of finite-sample Genome-Wide Association Studies (GWASs), it is a noisy approximation of the true latent genetic predisposition to a certain trait. The conventional way of boosting the predictive power of polygenic scores is to … Read more

Investigating the genetic architecture of noncognitive skills using GWAS-by-subtraction

Little is known about the genetic architecture of traits affecting educational attainment other than cognitive ability. We used genomic structural equation modeling and prior genome-wide association studies (GWASs) of educational attainment (n = 1,131,881) and cognitive test performance (n = 257,841) to estimate SNP associations with educational attainment variation that is independent of cognitive ability. … Read more

Dynamic complementarity in skill production: Evidence from genetic endowments and birth order

This study looks at how nature and nurture interact in influencing individuals academic attainment, and finds support for the theory that early life parental inputs increase later gains – especially in those children who have genetic advantages. The researchers used data on a sample of 15,000 siblings, whose genetic and demographic information is stored in … Read more

Attention Deficit Hyperactivity Disorder (ADHD) and Earnings in Later-Life Self-Employment

It has been suggested that individuals with ADHD are likely to go into self-employment, where a flair for entrepreneurship may improve their prospects. But this study suggests the choice of self-employment may not always be a positive one for those with this condition. This paper asks two questions: Are those with a genetic predisposition to … Read more

ADHD and later-life labor market outcomes in the United States

Authors: ,
Issue: 2019
Themes: ,

People at genetic risk of Attention Deficit Hyperactivity Disorder (ADHD) suffer negative effects on their employment, individual income and household wealth. But these can probably be mitigated by higher educational attainment, this paper finds. The researchers looked at a sample of approximately 9,000 individuals aged 50-65 who took part in the American Health and Retirement … Read more

Effect of Genetic Propensity for Obesity on Income and Wealth Through Educational Attainment

This paper shows that a genetic propensity to obesity affects women more than men in the labour market. The research draws on a representative sample of almost 6,000 Americans aged 50-65 and not yet retired from the US Health and Retirement Study. It looks at factors such as individual income, household wealth, health and retirement … Read more
