Urban Density and Pupil Attainment We explore the association between urban density and pupil attainment using three cohorts of pupils in schooling in England. Although – as widely recognised – attainment in dense urban places is low on average, this is not because urban environments disadvantage pupils, but because the most disadvantaged pupils with low average attainments attend the most urba...

PARTICIPANTS, METHODS, AND RESULTS In a cohort of 14 193 men and women born in Uppsala in 1915–1929, we studied the associations of fetal growth rate and length of gestation with the risk of death from ischaemic heart disease (ICD 7: 420–422; 8 and 9: 410–414; 10: I20–25) and cerebrovascular disease (ICD 7: 330–334; 8 and 9: 430– 438, 10: I60–69). Occlusive strokes include ICD7: 332–334, ICD8: ...

We evaluate the impact of joint-liability incentives in the classroom using a randomized field experiment. The instructor designs groups of three students in the classroom and provides a premium to their homework's grade only if all three members of the group meet some requirements. To isolate the joint-liability effect from selfish motivations, we also design an individual incentives treatment...

Performance targets are ubiquitous in all areas of an individual’s life, such as education, jobs, sport competitions and charity donations. In this paper I assess whether meeting performance targets in tests at school has an effect on students’ subsequent behaviour. This is helpful to test whether motivation and effort by students, parents and schools, that the targets may induce, may deter rat...

In several school choice districts in the United States, the student proposing deferred acceptance algorithm is applied after indifferences in priority orders are broken in some exogenous way. Although such a tie-breaking procedure preserves stability, it adversely affects the welfare of the students since it introduces artificial stability constraints. Our main finding is a polynomial-time alg...

OBJECTIVE Cardiovascular diseases (CVDs) are still the leading cause of death worldwide despite the recent decline in mortality rates attributable to CVD in Western Europe and the Americas. The aim of this study is to investigate mortality trends due to ischaemic heart disease (IHD) and stroke in Panama from 2001 to 2014, as well as the mortality differences by sex and age groups. METHODS Dat...

The College Wage Premium, Overeducation, and the Expansion of Higher Education in the UK This paper provides findings from the UK Labour Force Surveys from 1996 to 2003 on the financial private returns to a degree – the “college premium”. The data covers a decade when the university participation rate doubled – yet we find no significant evidence that the mean return to a degree dropped in resp...

The extensive research on teacher quality has led to two conclusions. First, there are large and significant differences among teachers in terms of their capacity to improve student achievement. Second, these differences are not captured by common measures of teacher qualifications (E.A. Hanushek, Teacher quality, in: L.T. Izumi, W.M. Evers (Eds.), Teacher Quality, Hoover Press, Palo Alto, CA, ...

Heart disease (HD) remains the leading cause of death among Mississippians; however, despite the importance of the condition, trends in HD mortality in Mississippi have not been adequately explored. This study examined trends in HD mortality among adults in Mississippi from 1980 through 2013 and further examined these trends by race and sex. We used data from Mississippi Vital Statistics (1980-...
