Science rests upon the reliability of peer review. This paper suggests a way to test for bias. It is able to avoid the fallacy - one seen in the popular press and the research literature - that to measure discrimination it is sufficient to study averages within two populations. The paper's...

One theory for why there is a strong education gradient in health outcomes is that more educated individuals more quickly absorb new information about health technology. The MMR controversy in the UK provides a case where, for a brief period of time, some highly publicized research suggested...

One of the famous questions in social science is whether money makes people happy. We offer new evidence by using longitudinal data on a random sample of Britons who receive medium-sized lottery wins of between Đ1000 and Đ120,000 (that is, up to approximately U.S. $200,000). When compared to...

This paper provides evidence that daughters make people more left-wing. Having sons, by contrast, makes them more right-wing. Parents, politicians and voters are probably not aware of this phenomenon -- nor are social scientists. The paper discusses its economic and evolutionary roots. It also...

This paper uses longitudinal data to explore whether greater job status makes a person healthier. Taking the evidence as a whole, promotees do not exhibit a health improvement after promotion. Instead the data suggest that workers with good health are more likely to be promoted. In the private...

Countries often spend billions on university research. There is growing interest in how to assess whether that money is well spent. Is there an objective way to assess the quality of a nation's world-leading science? I attempt to suggest a method, and illustrate it with modern data on economics....

"Low birth weight has considerable short and long-term consequences and leads to high costs to the individual and society even in a developed economy. Low birth weight is partially a consequence of choices made by the mother pre- and during pregnancy. Thus policies affecting these choices could...

"We study the impact of labour turnover on labour productivity using a panel dataset of 347 shops belonging to a large UK clothing retailer over1995-1999. For the within-shop link -- holding constant the shop's permanent characteristics -- we observe an inverted U-shape effect of labour turnover...

We live in a high-divorce age. It is now common for university faculty to have students who are touched by a recent divorce. It is likely that parents themselves worry about effects on their children. Yet there has been almost no formal research into the important issue of how recent...

This paper studies the mental distress caused by bereavement. The largest emotional losses are from the death of a spouse; the second-worst in severity are the losses from the death of a child; the third-worst is the death of a parent. The paper explores how happiness regression equations might be...
