Consensus forecasts are ine¢ cient. The weight placed on new information re‡ects the choices of the underlying individual forecasters— whose new information is noisier individually than in aggregate— so that the consensus forecast overweights older information. Using a cross-country panel of growth forecasts and new methodological insights, this paper …nds that: consensus forecasts are ine¢ cie...

GH deficiency is associated with increased cardiovascular mortality and early manifestations of atherosclerosis. Elevated serum homocyst(e)ine levels have been found to be associated with increased cardiovascular risk. The effect of GH replacement on homocyst(e)ine has not been investigated to date. We evaluated the effect of GH replacement on fasting homocyst(e)inemia in a group of men with ad...

Hyperhomocyst(e)inaemia is associated with endothelial dysfunction in animals and humans. Mechanisms responsible for endothelial dysfunction in hyperhomocyst(e)inaemia are poorly understood, but may involve impaired bioavailability of endothelium-derived nitric oxide (NO). We hypothesized that acute elevation of homocyst(e)ine by oral methionine loading may stimulate the formation of asymmetric...

Elevated plasma homocyst(e)ine levels are an independent risk factor for vascular disease. In a case-control study, the authors studied the associations of fasting plasma homocyst(e)ine and vitamins, which are important cofactors in homocysteine metabolism, with the risk of myocardial infarction. The cases were 130 Boston area patients hospitalized with a first myocardial infarction and 118 pop...

The brooding and reflection forms of rumination were examined as mediators of the concurrent relationship between the impact of negative life events (INE), symptoms of depression, and suicidal ideation. An ethnically diverse sample of college undergraduates (N = 1,011) completed measures of negative life events and rumination, and they reported on their symptoms of depression and suicidal ideat...
