    Estimating the External Returns to Education: Evidence from China
    (University College Dublin. School of Economics, 2012-08) ;
    Good understanding on the human capital externalities is important for both policy makers and social science researchers. Economists have speculated for at least a century that the social returns to education may exceed the private returns. In this paper, using the longitudinal data from China Health and Nutrition Survey (CHNS), we examine how individual wage changes associated with the share of college graduates in the same province across years for a person who has never moved by implementing individual fixed effects estimates. The individual fixed effect model shows that the external returns to education in China appear to be negative and on the order of -2%, which might be biased by potential endogeneity. Concerned with this problem, we then implement the IV fixed effect estimates and find positive external returns to education at about 10%. We also find this returns differ across individual heterogeneity.

    Earnings Returns to the British Education Expansion
    (University College Dublin. School of Economics, 2011-06) ;
    We study the effects of the large expansion in British educational attainment that took place for cohorts born between 1970 and 1975. Using the Quarterly Labour Force Survey, we find that the expansion caused men to increase education by about a year on average and gain about 8% higher wages; women obtained a slightly greater increase in education and a similar increase in wages. Clearly, there was a sizeable gain from being born late enough to take advantage of the greater educational opportunities offered by the expansion. Treating the expansion as an exogenous increase in educational attainment, we obtain instrumental variables estimates of returns to schooling of about 6% for both men and women.

    Estimating the return to college in Britain using regression and propensity score matching
    (University College Dublin. School of Economics, 2011-09)
    College graduates tend to earn more than non-graduates but it is difficult to ascertain how much of this empirical association between wages and college degree is due to the causal effect of a college degree and how much is due to unobserved factors that influence both wages and education (e.g. ability). In this paper, I use the 1970 British Cohort Study to examine the college premium for people who have a similar ability level by using a restricted sample of people who are all college eligible but some never attend. Compared to using the full sample, restricting the sample to college-eligible reduces the return to college significantly using both regression and propensity score matching (PSM) estimates. The finding suggests the importance of comparing individuals of similar ability levels when estimating the return to college.

    School tenure and student achievement
    (University College Dublin. School of Economics, 2011-11)
    While much empirical work concerns job tenure, this paper introduces the concept of school tenure -- the length of time one student has been in a given school. I examine whether and how school tenure impacts students’ output using rich cohort data on England’s secondary schools. Ordinary Least Squares (OLS) estimates suggest that, on average, students benefit from longer own school tenure but suffer from that of their peers. Using the number of times the student moved school during the academic year as an instrument for school tenure to deal with potential endogeneity, the resulting Two-Stage Least Squares (TSLS) estimates suggest the effects of school tenure are positive and heterogeneous across students. While advantaged students are more likely to gain from own longer school tenure, disadvantaged ones are benefit if their peers have longer tenure.

    The Four Day Week: Assessing global trials of reduced work time with no reduction in pay: Evidence from Ireland
    Research suggests that worktime reduction is a multi-dividend policy that can improve human wellbeing, organisational performance, and environmental outcomes. Social benefits include reduced stress and burnout for employees and more time for family, community, and self. Economic benefits depend on the form of worktime reduction. Where it is accomplished without loss or even gains in productivity, it is beneficial for companies’ bottom lines. Environmental benefits can accrue reduced energy expended in commuting, especially with four-day work weeks; increases in low carbon but time-intensive practices for households; and reduced carbon emissions due to trading income for a time. As the most popular form of worktime reduction, a four-day, 32-hour workweek has been gaining momentum in recent years. Given this growth in interest, Four Day Week Global (4DWG) began supporting companies and non-profit organisations that wanted to try a four-day, 32-hour workweek with no reduction in pay. Boston College leads the research team in partnership with University College Dublin, Cambridge University and other academic partners. We are constructing a sizeable quantitative database of employee outcomes across different countries and types of companies and organisations. We collected data on time use, subjective wellbeing, physical and mental health, labour market behaviour, and energy use with a wide-ranging instrument. In February 2022, 4DWG launched the first of several coordinated international trials. It involved 614 employees across Ireland, the United States, Australia, and New Zealand. The research involved (i) surveying employees at the beginning, midpoint and end of the trial, (ii) compiling time-use diaries of employees’ days off, (iii) collecting monthly data on organisational performance and (iv) interviewing employees and managers at the end of the trial1. This report presents detailed results of a subset of Irish organisations and their employees participating in the trial. This group comprised 12 small to medium enterprises, primarily concentrated in the IT and professional services sectors.
