EXPONENTIAL‐GROWTH BIAS AND LIFECYCLE CONSUMPTION

Exponential‐growth bias (EGB) is the tendency for individuals to partially neglect compounding of exponential growth. We develop a model wherein biased agents misperceive the intertemporal budget constraint, and derive conditions for overconsumption and dynamic inconsistency. We construct an incentivized measure of EGB in a US‐representative population and find substantial bias, with approximately one third of subjects estimated as the fully biased type. The magnitude of the bias is negatively associated with asset accumulation, and does not respond to a simple graphical intervention.     

To be or not to be: the effects of aging stereotypes on the will to live

This study examined whether stereotypes of aging might contribute to decisions the elderly make about when to die. Old and young participants (N=64) were subliminally primed with either negative or positive stereotypes of old age and then responded to hypothetical medical situations involving potentially fatal illnesses. Consistent with our prediction, the aged participants primed with negative stereotypes tended to refuse life-prolonging interventions, whereas the old participants primed with positive age stereotypes tended to accept the interventions. This priming effect did not emerge among the young participants for whom the stereotypes were less relevant. The results suggest that societally-transmitted negative stereotypes of aging can weaken elderly people's will to live.     

Integrating risk assessment and life cycle assessment: a case study of insulation.

Increasing residential insulation can decrease energy consumption and provide public health benefits, given changes in emissions from fuel combustion, but also has cost implications and ancillary risks and benefits. Risk assessment or life cycle assessment can be used to calculate the net impacts and determine whether more stringent energy codes or other conservation policies would be warranted, but few analyses have combined the critical elements of both methodologies In this article, we present the first portion of a combined analysis, with the goal of estimating the net public health impacts of increasing residential insulation for new housing from current practice to the latest International Energy Conservation Code (IECC 2000). We model state-by-state residential energy savings and evaluate particulate matter less than 2.5 microm in diameter (PM2.5), NOx, and SO2 emission reductions. We use past dispersion modeling results to estimate reductions in exposure, and we apply concentration-response functions for premature mortality and selected morbidity outcomes using current epidemiological knowledge of effects of PM2.5 (primary and secondary). We find that an insulation policy shift would save 3 x 10(14) British thermal units or BTU (3 x 10(17) J) over a 10-year period, resulting in reduced emissions of 1,000 tons of PM2.5, 30,000 tons of NOx, and 40,000 tons of SO2. These emission reductions yield an estimated 60 fewer fatalities during this period, with the geographic distribution of health benefits differing from the distribution of energy savings because of differences in energy sources, population patterns, and meteorology. We discuss the methodology to be used to integrate life cycle calculations, which can ultimately yield estimates that can be compared with costs to determine the influence of external costs on benefit-cost calculations.     

American Public Opinion on Immigration: Nativist,Polarized, or Ambivalent?

For Dauvergne (2016), one consequence of the “end of settler societies” is nativism, or what she calls “mean-spirited politics”: anti-immigrant, anti-Muslim, anti-Multiculturalism. This accords with the prevailing tone of public opinion literature on the subject, which links anti-immigrant hostility in settler societies to influxes of diversity and associated racial threat. In this essay, we determine just how closely this stylized vision of anxiety-fuelled nativism resembles the true state of mass opinion about immigration. Using a variety of surveys fielded in recent years, we show that Americans: 1) hold generally positive views about immigration, though with a substantial dose of ambivalence about its consequences; 2) are not especially consistent in their policy attitudes over time; 3) express policy attitudes that readily depart from their underlying predispositions, and; 4) have only become more pro-immigrant in recent years, and whatever partisan polarization exists on the issue stems from the fact that Republicans are becoming more positive at a slightly slower pace than Democrats. All of this suggests that, while there is a hard core of ethnocentrism and "mean-spiritedness" in the U.S., the prevailing tone is much less negative than the standard portrayal assumes.     

Evaluating Efficiency-Equality Tradeoffs for Mobile Source Control Strategies in an Urban Area

In environmental risk management, there are often interests in maximizing public health benefits (efficiency) and addressing inequality in the distribution of health outcomes. However, both dimensions are not generally considered within a single analytical framework. In this study, we estimate both total population health benefits and changes in quantitative indicators of health inequality for a number of alternative spatial distributions of diesel particulate filter retrofits across half of an urban bus fleet in Boston, Massachusetts. We focus on the impact of emissions controls on primary fine particulate matter (PM_2.5) emissions, modeling the effect on PM_2.5 concentrations and premature mortality. Given spatial heterogeneity in baseline mortality rates, we apply the Atkinson index and other inequality indicators to quantify changes in the distribution of mortality risk. Across the different spatial distributions of control strategies, the public health benefits varied by more than a factor of two, related to factors such as mileage driven per day, population density near roadways, and baseline mortality rates in exposed populations. Changes in health inequality indicators varied across control strategies, with the subset of optimal strategies considering both efficiency and equality generally robust across different parametric assumptions and inequality indicators. Our analysis demonstrates the viability of formal analytical approaches to jointly address both efficiency and equality in risk assessment, providing a tool for decisionmakers who wish to consider both issues.     

A theory of happiness-wealth relationship with status-sensitive communication

Personal happiness might not solely depend on the individual's level of wealth but also on the individual's level of sincere social capital. This paper argues that if sincere interpersonal communication is sensitive to economic status disparities, the accumulation of personal wealth beyond the community's average erodes the individual's sincere social capital. A measure of sincere social capital that is based on such sensitivity is constructed. Its consideration leads to the depiction of the individual's happiness-wealth relationship as an inverted U-shaped curve that peaks at personal wealth that is greater than the community mean.     

Communities under fire: Empowering families and children in the aftermath of homicide

This article presents an empowerment approach to clinical services for families and children surviving homicides. Narrative theory is used to integrate child, family and community interventions. The article presents a framework for the examination of narratives and guidelines for co-constructing narratives that empower children, families and communities.     

Framing the experiences of BME social work students within a narrative of Educating for a Culturally Diverse Workforce

The Scottish Social Services Council (SSSC) has noted that a higher percentage of black and minority ethnic (BME) students fail or take longer to complete their social work degrees, compared with the white majority student population. In response to this and related evidence, a national study was carried out in 2013 to explore this phenomenon and ways to support BME students in social work education in Scotland. BME students from five Scottish universities were interviewed, along with lecturers from six Scottish Universities, and practice educators from around Scotland. The background to the study is discussed and a review of the literature on race, whiteness, diversity and a strengths-based perspective is provided. The methodology of the study is explained, followed by a presentation of some of the key findings covering the themes of cultural difference, discrimination and valuing student strengths. To prepare social work students to practice in a culturally diverse and culturally aware workforce the paper argues for framing of social work education within a strengths-based perspective, of valuing diversity and other knowledges and for this approach to be embedded within a critique of both race and whiteness.
