In this paper I focus on two specific hazard areas in the transition from Stage Two to Stage Three of European economic and monetary union (EMU), as well as on some key problems of Stage Three that EMU's monetary and fiscal structures appear ill-prepared to handle. The transitional hazards are...

Diesel emissions from school buses expose children to high levels of air pollution; retrofitting bus engines can substantially reduce this exposure. Using variation from 2,656 retrofits across Georgia, we estimate effects of emissions reductions on district-level health and academic achievement....

The repeated failure of Ireland's potato crop in the late 1840s led to a major famine and a surge in migration to the US. We build a dataset of Irish immigrants and their sons by linking males from 1850 to 1880 US census records. For comparison, we also link German and British immigrants, their...

We analyse whether research funding contests promote co-authorship. Our analysis combines Scopus publication records with data on applications to the Marsden Fund, the premiere source of funding for basic research in New Zealand. On average, and after controlling for observable and unobservable...

Previous research has shown a strong connection between birth weight and future child outcomes. But this research has not asked how insults to child health after birth affect long-term outcomes, whether health at birth matters primarily because it predicts future health or through some other...

The information content of academic citations is subject to debate. This paper views premature death as a tragic "natural experiment," outlining a methodology identifying the "citation death tax" -- the impact of death of productive economists on the patterns of their citations. We rely on a...

Obesity has been one of the fastest growing health concerns among children, particularly among disadvantaged children. For children overall, obesity rates have tripled from 5% in the early 1970s to about 15% by the early 2000s. For disadvantaged children, obesity rates are closer to 20%. In this...

Recently, Currie and Stabile (2006) made a significant contribution to our understanding of the influence of ADHD symptoms on a variety of school outcomes including participation in special education, grade repetition and test scores. Their contributions include using a broad sample of children...

Although mental disorders are common among children, we know little about their long term effects on child outcomes. This paper examines U.S. and Canadian children with symptoms of Attention Deficit Hyperactivity Disorder (ADHD), depression, conduct disorders, and other behavioral problems. Our...

This paper proposes a framework to account for innovation similar to the usual accounting framework in production analysis and a measure of innovativity comparable to that of total factor productivity. This innovation accounting framework is illustrated using micro-aggregated firm data from the...
