ATSDR Science Panel on the Bioavailability of Mercury in Soils: Lessons Learned

On the basis of discussion and analysis during and following an ATSDR science panel on the bioavailability of mercury in soils, it is apparent that the default assumption of 100% relative bioavailability for mercury-contaminated soils is excessively conservative. However, current knowledge does not allow the development of default assumptions or guidelines for determining relative bioavailability of mercury in soils. Until such default assumptions or guidelines can be developed, site-specific assays of bioavailability, preferably using either animal bioassays or validated in vitro techniques, may provide the best approach for estimating soil-mercury bioavailability.     

Financial literacy and the design of retirement plans

We design and administer a financial literacy test tailored to a specific defined contribution plan. We find that participants show fairly good knowledge of the basic mechanics of the plan, but are unable to differentiate among various investment options. Knowledge is particularly low among women, low income and low education employees. We also find some evidence that personal contributions lead to more knowledge. These results support plan designs that have few investment options and encourage personal contributions.

Earnings inequality and subnational political economy in the United States, 1970–2000

Previous studies of rising inequality in the United States have overlooked the potential role of subnational political economic variation as an institution that shapes earnings restructuring. This paper uses hierarchical linear models to examine how state right-to-work laws contribute to growth in inequality in 80 metropolitan labor markets from 1970 to 2000. Contrary to conventional expectations, labor markets in states with right-to-work laws experience relatively mild growth in earnings inequality, and are less unequal by 2000 than non-RTW labor markets. The trend cannot be fully explained by union density, job growth, uneven development or variation in racial inequality. The findings contribute to a distinctly sociological perspective on rising inequality that considers how social, institutional and economic factors interact at the local and state levels to shape earnings.
