There are growing concerns about the impact of pollution on maternal and infant health. Despite an extensive correlational literature, observational studies which adopt methods that seek to address potential biases due to unmeasured confounders draw mixed conclusions. Using a population database of births in Northern Ireland (NI) linked to localized geographic information on pollution in mothers' postcodes (zipcodes) of residence during pregnancy, we examine whether prenatal exposure to PM2.5 is associated with a comprehensive range of birth outcomes, including placental health. Overall, we find little evidence that particulate matter is related to infant outcomes at the pollution levels experienced in NI, once we implement a mother fixed effects approach that accounts for time‐invariant factors. This contrasts with strong associations in models that adjust for observed confounders but without fixed effects. While reducing ambient air pollution remains an urgent public health priority globally, our results imply that further improvements in short‐run levels of prenatal PM2.5 exposure in a relatively low‐pollution, higher‐income country context, are unlikely to impact on birth outcomes at the population level.

Vocational education and training provision for young people is a crucial but often maligned part of the wider education sector. A common criticism, and motivation for numerous reforms across countries where training is predominantly classroom-based, is that too much training is low quality and unrelated to skill needs. This article examines the effects of a major Australian reform--replacing a centrally planned model with a system-wide voucher scheme--aimed at addressing these weaknesses. The reform led to large increases in private college enrollments, improved match between course choice and employer demand, and improved student achievement, with no adverse impact on equity.

Despite an extensive literature on Catholic-Protestant unemployment differentials in Northern Ireland, little is known about wage differentials. This paper provides new evidence using the Earnings and Employees Study for 2011. We find no evidence of an overall Catholic wage penalty, with unadjusted and adjusted differentials no larger than 1.4 log per cent and statistically insignificant. Slightly larger differentials are found in some models for men, 50+ workers, and private sector workers, but again these are statistically indistinguishable from zero. Similar data linkages for 2001 and 1991 would enrich our understanding of the period when other measurable labour market disparities were wider. [ABSTRACT FROM AUTHOR]

This article examines associations between precarious contract types and a range of self‐reported health measures for the UK. We focus on zero hours contracts (ZHCs), an extreme form of precarious employment that has grown rapidly in the UK over the last decade, and on mental health. We demonstrate that workers employed on ZHCs are more likely to report a long‐term health condition than workers employed on other types of contract, with the main driver being that they are almost twice as likely to report mental ill health. These associations survive conditioning on an extensive set of observable individual, job and contextual characteristics, and are robust to sensitivity analysis designed to explore the likely extent of bias due to unobserved confounders. We discuss potential explanations for these associations, from sorting of workers with poor health into ZHC employment to detrimental effects of ZHC employment on health, drawing on additional instrumental variables estimates to do so. Finally, we discuss potential policy implications. [ABSTRACT FROM AUTHOR]

This paper examines the impacts of the introduction of the UK National Minimum Wage (NMW) in 1999 and the introduction of the UK National Living Wage (NLW) in 2016 in Northern Ireland (NI) on employment and hours. NI is the only part of the UK with a land border where the NMW and NLW cover those working on one side of the border but not those working on the other side of the border (i.e., Republic of Ireland). This discontinuity in minimum wage coverage enables a research design that estimates the impacts of the NMW and NLW on employment and hours worked using difference-in-differences estimation. We find a small decrease in the employment rate of 22–59/64-year-olds in NI, of up to 2% points, in the year following the introduction of the NMW, but no impact on hours worked. We find no clear evidence that the introduction of the NLW impacted either employment or hours worked in NI.

Suspension from school is a commonly used, yet controversial, school disciplinary measure. This paper uses unique survey data to estimate the impact of suspension on the educational outcomes of those suspended. It finds that while suspension is strongly associated with educational outcomes, the relationship is unlikely to be causal, but rather likely stems from differences in the characteristics of those suspended compared to those not suspended. Moreover, there is no evidence that suspension is associated with larger educational penalties for young people from disadvantaged family backgrounds compared to those from more advantaged family backgrounds. These results hold regardless of whether self-reported suspension or mother-reported suspension is considered. The absence of a clear negative causal impact of suspension on educational outcomes suggests that suspension may continue to play a role in school discipline without harming the educational prospects of those sanctioned.

This article provides a comprehensive analysis of the dynamic relationship between disability and welfare benefit receipt in Britain. Exploiting rarely used longitudinal data, it examines the impact of disability onset and disability exit on receipt of a range of beneficial outcomes, utilizing differences in the timing of onset/exit for identification. Disability onset increases receipt of disability insurance (DI), sickness benefits, and non-sickness benefits by 6, 8, and 9 percentage points in the onset year, although almost 70% of those experiencing onset remain independent of the welfare system in the short-run. DI reforms that toughened screening, reduced generosity, and increased conditionality appear to have substantially reduced DI inflows following onset, but without affecting the overall probability of welfare receipt. Disability exit , although neglected in the literature, is common during working-age and leads to a decrease in DI (and total welfare receipt), suggesting DI is not an absorbing state.

Ethnic and religious differentials in labour market outcomes within many countries have been remarkably persistent. Yet one very well‐known differential—the Catholic/Protestant unemployment differential in Northern Ireland—has largely (although not completely) disappeared. This paper charts its decline since the early 1980s and examines potential explanations using Census data from 1991, 2001 and 2011 together with annual survey data. These data span the ending of The Troubles, the signing of the Good Friday Agreement, the introduction of fair employment legislation, growth in hidden unemployment and major structural changes in Northern Ireland. We assess the potential impact of these changes. [ABSTRACT FROM AUTHOR]
