Lorraine Dearden's research interests include the impact of education policies on beneficiaries' education and labour market outcomes, ethnic inequality in childhood outcomes, higher education finance, wage determination, and intergenerational mobility. According to IDEAS/RePEc, Dearden ranks among the top 5% of economists in terms of research output.
Dearden has conducted extensive research on the determinants and returns to education along with Richard Blundell, Costas Meghir, Barbara Sianesi, Alissa Goodman, Howard Reed, and Anna Vignoles. Together with Blundell and Meghir, she finds that, in Britain in the 1980s, both the highly educated and men were substantially more susceptible to receive employer-provided training and work-related training than women, with training increasing workers' real earnings by 5% and up to 10% in case of graduation over 10 years and the returns to training persisting through changes in employers. Reviewing the evidence on the returns to education and training prior to the mid-2000s, they - along with Sianesi - conclude that "there is a substantial body of evidence on the contribution of education to economic growth". In further work, Dearden, Blundell, Goodman and Reed estimate that, controlling for individual characteristics, an undergraduate degree raised the earnings of Britishmen and women from the 1958 cohort by, on average, 17% and 37%, respectively, with lower returns for higher degrees and non-degree higher education. Together with Vignoles, Steven McIntosh and Michal Myck, Dearden further finds that the wage premia for vocational qualifications in the UK in the 1990s were generally lower than those of academic qualifications. Moreover, Dearden, Meghir and Javier Ferri find that the pupil-teacher ratio in the UK has generally no impact on educational qualifications or on men's wages but on those of low-ability women and that attending selective schools improves educational outcomes and, for men, also wages. Finally, Dearden, Blundell and Sianesi estimate that, compared to dropping out of secondary school at age 16, O-levels raise earnings by 18%, A-levels by 24% and higher education by 48%.
Other research
Together with Stephen Machin and Howard Reed, Dearden found that intergenerational mobility in Britain from the 1960s to the 1990s was low as upward mobility from the bottom of the wage distribution fails to compensate for the rigidity of downward mobility from its top.
Dearden, Reed and van Reenen estimate that, for Britain industries in 1983-96, a 1% increase in training was associated with an increase in hourly value added of about 0.6% and an increase in hourly wages by about 0.3%, with individual data suggesting training externalities.
Analysing the determinants of higher education participation in England, Dearden, Haroon Chowdry, Claire Crawford, Alissa Goodman and Anna Vignoles find that the large differences by socioeconomic background in participation rates in general and at high-status universities in particular are substantially reduced once prior educational attainment is included, suggesting that policy should prioritize improving secondary education for students from poor backgrounds over addressing barriers at the point of entry to higher education.
Studying the existence of a 'moral economy' as social security system in Java, Dearden and Martin Ravallion find large differences between urban and rural areas, with private transfer payments helping to reduce income inequality and being targeted to disadvantaged households such as the sick or elderly in the former.
Dearden, Crawford and Meghir have also argued that there is a significant penalty associated with date of birth, with the youngest children in a particular academic year performing significantly worse in academic tests than older children, and that the penalty persists until adulthood, thereby putting summer-born children at a disadvantage.
