The effect of breastfeeding on young adult wages: new evidence from the add health

A growing literature in economics has examined the effect of early childhood health investments on adult human capital formation and labor market outcomes. This study is the first to examine the effect of having been breastfed as an infant on young adult earnings. Using data from the National Longitudinal Study of Adolescent Health (Add Health), ordinary least squares estimates suggest that breastfeeding is associated with a 10–12 % increase in hourly earnings. However, after ensuring common support on observables via propensity score matching and controlling for unmeasured family level heterogeneity common to siblings via family fixed effects, the estimated associations become much smaller and are statistically indistinguishable from zero. We conclude that the benefits of having been breastfed do not appear to extend to the labor market.     

Pictorial Approaches for Measuring Time Use in Rural Ethiopia

Time use researchers working in least developed countries (LDCs) face difficulties collecting data from illiterate populations who may conceptualize time differently than those in industrialized countries. We identify existing gaps in time use data collection methods and discuss two novel, pictorial methods to collect time use data from these populations. The first method is a modified recall interview modeled on participatory rural appraisal (PRA) methods that asks respondents to place macaroni on pictures of activity categories in proportion to the amount of time spent on that activity during the previous day. The second is a simplified pictorial time diary that uses a timer and sequentially-numbered stickers to re-create the temporal order of activities in 30-min increments. The latter method also avoids recall bias problems. We present time use data collected in 2009 using these methods in a study examining the impacts of water infrastructure on women and children’s time use in rural Ethiopia. In total, we collected information using the first method from 263 household members over age 10, including 167 water collectors, and pilot-tested the pictorial diary approach with 10 adult respondents.     

Hybrid Strategies: Allocating Involvement in the Digital Age

An important trait of mobile phones is their capacity to superimpose multiple social interactions in time and space. Little research examines how individuals choose between face‐to‐face and digitally mediated interactions in specific social contexts. Drawing upon focus group interviews with a diverse sample of university students in the United States, we argue that, contrary to a perspective that is popular in theory and journalistic commentary, mobile phone users do not experience the digital and the face‐to‐face as distinct realms. In deciding where to direct their attention, users enmesh the distant and the present, making moves that are expressive and strategic in their own right that reveal the interest, intimacy and urgency that users place in multiple, coinciding social involvements.     

Contextualizing corporate control in the agrifood and extractive sectors

ABSTRACT

Corporations have gained enormous power and influence in recent decades as mergers and acquisitions in just about every sector of the global economy have given rise to mega-sized companies that influence almost every aspect of our lives. In this contribution, we examine the rise of corporate concentration and control in two key sectors – agriculture and extractives – where in recent years consolidation has accelerated due to a combination of technological change, weakening state regulation and financial pressures, leaving these sectors largely controlled by just a handful of giant players. Corporate concentration and control in these sectors has important consequences, contributing to heightened inequality, environmental harm, and human rights violations. This paper reflects on the strategies of civil society and social movements in contesting extreme consolidation and corporate power. It calls for a multiscale approach that restores the regulatory powers of states and reestablishes people's sovereignty on a broader scale.     

Expanding the Reach of Participatory Risk Management: Testing an Online Decision‐Aiding Framework for Informing Internally Consistent Choices

This article presents research aimed at developing and testing an online, multistakeholder decision‐aiding framework for informing multiattribute risk management choices associated with energy development and climate change. The framework was designed to provide necessary background information and facilitate internally consistent choices, or choices that are in line with users’ prioritized objectives. In order to test different components of the decision‐aiding framework, a six‐part, 2 × 2 × 2 factorial experiment was conducted, yielding eight treatment scenarios. The three factors included: (1) whether or not users could construct their own alternatives; (2) the level of detail regarding the composition of alternatives users would evaluate; and (3) the way in which a final choice between users’ own constructed (or highest‐ranked) portfolio and an internally consistent portfolio was presented. Participants’ self‐reports revealed the framework was easy to use and providing an opportunity to develop one's own risk‐management alternatives (Factor 1) led to the highest knowledge gains. Empirical measures showed the internal consistency of users’ decisions across all treatments to be lower than expected and confirmed that providing information about alternatives’ composition (Factor 2) resulted in the least internally consistent choices. At the same time, those users who did not develop their own alternatives and were not shown detailed information about the composition of alternatives believed their choices to be the most internally consistent. These results raise concerns about how the amount of information provided and the ability to construct alternatives may inversely affect users’ real and perceived internal consistency.     

Framing Effects in Narrative and Non‐Narrative Risk Messages

Narrative messages are increasingly popular in health and risk campaigns, yet gain/loss framing effects have never been tested with such messages. Three experiments examined framing in narrative messages. Experiment 1 found that only the character's decision, not framing, influenced judgments about characters in a narrative derived from a prospect theory context. Experiment 2 found that a framing effect that occurred when presented in a decision format did not occur when the same situation was presented as a narrative. Using a different story/decision context, Experiment 3 found no significant difference in preference for surgery over radiation therapy in a narrative presentation compared to a non‐narrative presentation. The results suggest that health and risk campaigns cannot assume that framing effects will be the same in narrative messages and non‐narrative messages. Potential reasons for these differences and suggestions for future research are discussed.     

Sex differences in remarriage and spouse selection

This paper explores on an international basis the incidence of remarriage among total marriages, the levels and differences in remarriage rates among widowed and divorced males and females, and differences between males and females in spouse selection according to the previous marital statuses of spouse and bride or groom. Remarriage rates by sex and previous marital status are estimated using vital registration data in combination with census information; there are 47 countries that have such data. The results of the analyses indicate that there are a number of general patterns of remarriage and spouse selection that tend to hold across countries.     

How Neighborhood Features Affect Quality of Life

In this paper we report on the development ofthree conceptual models that explain howsatisfaction with neighborhood features affectresidents' quality of life (life satisfaction). The first model posits that satisfaction withsocial, economic, and physical features of theneighborhood affects life satisfaction throughthe mediation effect of one's overall feelingstoward the neighborhood. That is, satisfactionwith the social, economic, and physicalfeatures tend to contribute to one's overallsatisfaction with the neighborhood(neighborhood satisfaction), which in turnplays a positive role in overall feelingstoward life (life satisfaction). Survey datafrom a variety of communities located insouthwest Virginia were collected, and the datafailed to provide support to this model. The second model posits that satisfaction withthe neighborhood features (social, economic,and physical) does affect life satisfactionthrough a hierarchy-of-satisfaction effects –satisfaction with the neighborhood featuresimpacts neighborhood satisfaction, which inturn affects community satisfaction and housingsatisfaction. Housing satisfaction, in turn,affects home satisfaction. Both homesatisfaction and community satisfaction, inturn, affect life satisfaction. The surveydata failed to support this model too. The third model posits that satisfaction withdifferent features of the neighborhood (social,economic, and physical) affect different domainsatisfactions, which in turn affect lifesatisfaction. Specifically, the model arguesthat satisfaction with the physical featuresaffects both neighborhood satisfaction andhousing satisfaction. Neighborhoodsatisfaction plays a role in communitysatisfaction, whereas housing satisfactionplays a role in home satisfaction. Bothcommunity satisfaction and home satisfaction,in turn, play a role in life satisfaction. Satisfaction with the social features of theneighborhood plays a role in the satisfactionwith the neighborhood and the community – thelatter feeds into life satisfaction. Satisfaction with the economic features of theneighborhood plays a role in the satisfactionwith the house and home – the latter feeds intolife satisfaction. The data were mostly supportive of this model.     

Variations in nutritional risk among black and white women who receive home-delivered meals

The maintenance of good nutritional status is a cornerstone of health, function, and quality of life. To assess indicators and correlates of high levels of nutritional risk, sociodemographic, functional status, and nutritional data were collected from a diverse sample of 729 older women. Results from ordered logit analysis indicated that being Black, having an income < or = 125% of the federal poverty level, living alone, and being in the younger-old age group (ages 60 to 74 years) were associated with moderately high and very high levels of nutritional risk. An examination of individual and multiple nutritional risk indicators suggested a heightened vulnerability of Black women to inadequate dietary intake, even net of income and other influential variables. With demographic projections of an increasingly numerous and diverse older population who may face health and nutritional challenges, researchers must strengthen efforts to assist policymakers and service providers to properly target nutrition services.
