This article uses baseline data from an observational study to estimate the determinants of racial and gender disparities in obesity. Samples of low-income workers in Minneapolis and Raleigh reveal that respondents in Minneapolis have lower body mass indices (BMIs) than respondents in Raleigh. There are large, statistically significant race and gender effects in estimates of BMI that explain most of the disparity between the two cities. Accounting for intersectionality—the joint impacts of being Black and a woman—reveals that almost all the BMI gaps between Black women in Minneapolis and Raleigh can be explained by age and education differences.

We review 1982–1984 articles identifying Superfund sites in three national newspapers. Articles almost never identify the race of nearby residents. Based on sites receiving disproportionate coverage, readers might conclude that Superfund generally affected white, working-class families, but results do not support this narrative. In a pooled sample, neither race nor income predicts the number of times a site gets mentioned. When the sample is partitioned by newspaper or by each newspaper's coverage of nearby sites, a positive relationship emerges between the proportion of Hispanic or nonwhite residents and the number of articles about a site. We discuss this apparent contradiction.

Previous studies indicate that “hesitation” and “skepticism” are important barriers to the development of renewable energy industries in the United States. We examine whether key pecuniary and nonpecuniary characteristics of bioenergy crops underlie the hesitation argument. Based on a stated choice experiment, we find that Midwestern producers appreciate certain crop attributes that are found in switchgrass, but not in conventional crops. We also find that producers would be willing to grow switchgrass-like crops for net margins between $222/acre/year and $247/acre/year in marginal counties. We argue that farmers’ hesitation and skepticism toward bioenergy crops can be overcome.

This article has used the method of instrumental variables to evaluate the impact of health services on the productivity of rural households’ farming labor in Burkina Faso. The distance from the household's homestead to the Health and Social Promotion Center (HSPC) was considered as an instrumental variable. The results revealed that resorting to a HSPC in case of an unexpected illness in the rainy season significantly improves the farm labor productivity by FCFA 3170.5880 per person-day. For improving agricultural productivity, we suggest that public decision-makers should focus on the availability and the quality of HSPC services in rural areas.

Latent class analysis is applied to a hedonic price model to examine the presence of heterogeneity in consumer valuation of quality attributes in the Beninese rice market. Three classes of consumers are found in proportions of 5, 56, and 39 percent. We employ a partial equilibrium model and find modest gains in consumer surplus from an increase in head rice and reduction in chalkiness. The results provide evidence of market sorting, which should be taken into consideration in upgrading rice value chains. Also, it is important to assess potential gains from quality improvement to determine priorities for research and development.

We hypothesize that spatial spillovers among neighboring farms are not only driven by spatial proximity, but also by farm profitability considerations. This hypothesis is tested by examining the role of spatial spillovers in shaping somatic cell counts (SCC) on Wisconsin dairy farms. Results show that neighborhood links defined both in terms of geographic proximity and farm profitability give rise to spatial spillovers that affect SCC. Significant differences in the estimated spatial spillovers are observed when defining the neighborhood space in terms of both farm profitability and geographic proximity as opposed to geographic proximity alone, with the data favoring the former specification.
