"utdoor air pollution, largely from fossil fuel burning, is a major cause of morbidity and mortality in the United States, costing billions of dollars every year in health care and loss of productivity. The developing fetus and young child are especially vulnerable to neurotoxicants, such as polycyclic aromatic hydrocarbons (PAH) released to ambient air by combustion of fossil fuel and other organic material. Low-income populations are disproportionately exposed to air pollution. On the basis of the results of a prospective cohort study in a low-income population in New York City (NYC) that found a significant inverse association between child IQ and prenatal exposure to airborne PAH, we estimated the increase in IQ and related lifetime earnings in a low-income urban population as a result of a hypothesized modest reduction of ambient PAH concentrations in NYC of 0.25?ng/m3. For reference, the current estimated annual mean PAH concentration is ~1?ng/m3. Restricting to NYC Medicaid births and using a 5 per cent discount rate, we estimated the gain in lifetime earnings due to IQ increase for a single year cohort to be US$215 million (best estimate). Using much more conservative assumptions, the estimate was $43 million. This analysis suggests that a modest reduction in ambient concentrations of PAH is associated with substantial economic benefits to children."

"This paper takes an explanatory approach to the triggers of Human Resource (HR) outsourcing decisions and evaluates them empirically. Our data show that many German firms have never explicitly considered outsourcing of HR functions. Obviously, explicit outsourcing decisions do not come into being automatically but have to be triggered. We analyze theoretically and empirically which triggers are relevant. In our definition, HR outsourcing includes a broad range of internal HR functions and the respective, externally procured personnel services (e.g., temporary agency work, payroll accounting, interim management, outplacement services, HR consulting, placement services and others).
