This study, published in Environmental Health, screened U.S. National Health and Nutrition Examination Survey (NHANES) 2001-2008 biomonitoring data for 228 chemicals for race/ethnicity and income-related disparity. Defining six subgroups by race/ethnicity and income, the study assessed disparity by comparing the central tendency (geometric mean [GM]) of the biomonitoring concentrations of each subgroup to that of the reference subgroup (non-Hispanic white/High Income), adjusting for multiple comparisons using the Holm-Bonferroni procedure.

The purpose of this paper, published in Quantitative Economics, is to develop and estimate a new equilibrium model of public housing that acknowledges the fact that the demand for public housing may exceed the available supply. The study shows that ignoring these supply side restrictions leads to an inconsistent estimator of household preferences. The study outlines a number of findings about demand for public housing, like the fact that for each family that leaves public housing there are, on average, 3.8 families that would like to move into the vacated unit. 

Inter-related epidemics of HIV and injection drug use occur globally but are especially prevalent and expanding in low and middle-income countries (LMIC). The uptake and coverage of harm reduction interventions in LMIC remain at low levels. This editorial examines the current and future state of the art in evaluation of these interventions and makes recommendations to fill in the gaps in evaluation and enhance the evidence.

        

Abt Associates began a celebration of its 50-year anniversary with an in-depth panel discussion on the latest in social experiments in the U.S. and around the world. The March 11 discussion at MIT included some of the top minds in evaluation science who explored the challenges and successes in gathering reliable evidence on whether a program works.
