Abstract: Our social evaluation of other people is influenced by their faces and their voices. However, rather little is known about how these channels combine in forming “first impressions.” Over 5 experiments, we investigate the relative contributions of facial and vocal information for social judgments: dominance and trustworthiness. The experiments manipulate each of these sources of information within-person, combining faces and voices giving rise to different social attributions. We report that vocal pitch is a reliable source of information for judgments of dominance (Study 1), but not trustworthiness (Study 4). Faces and voices make reliable, but independent, contributions to social evaluation. However, voices have the larger influence in judgments of dominance (Study 2), whereas faces have the larger influence in judgments of trustworthiness (Study 5). The independent contribution of the 2 sources appears to be mandatory, as instructions to ignore 1 channel do not eliminate its influence (Study 3). Our results show that information contained in both the face and the voice contributes to first impression formation. This combination is, to some degree, outside conscious control, and the weighting of channel contribution varies according the trait being perceived.

Abstract
Objectives To investigate whether outcomes of patients who were admitted to hospital differ between those treated by younger and older physicians.
Design: Observational study.
Setting: US acute care hospitals.

Participants: 20% random sample of Medicare fee-for-service beneficiaries aged ≥65 admitted to hospital with a medical condition in 2011-14 and treated by hospitalist physicians to whom they were assigned based on scheduled work shifts. To assess the generalizability of findings, analyses also included patients treated by general internists including both hospitalists and non-hospitalists.
Main outcome measures 30 day mortality and readmissions and costs of care.

Results: 736 537 admissions managed by 18 854 hospitalist physicians (median age 41) were included. Patients’ characteristics were similar across physician ages. After adjustment for characteristics of patients and physicians and hospital fixed effects (effectively comparing physicians within the same hospital), patients’ adjusted 30 day mortality rates were 10.8% for physicians aged <40 10.7="" 10.9="" 11.1="" 11.3="" 11.5="" 12.1="" 12.5="" 40-49="" 40="" 50-59="" a="" age="" aged="" among="" analyses.="" and="" association="" between="" br="" care="" confidence="" costs="" did="" for="" general="" high="" higher="" however="" in="" internists="" interval="" mortality.="" no="" not="" observed="" of="" older="" patient="" patients="" patterns="" physician="" physicians.="" physicians="" readmissions="" sensitivity="" several="" similar="" slightly="" there="" to="" vary="" volume="" was="" were="" while="" with="">

Ethnic and linguistic fractionalization contributes to poverty levels

Ethnic Diversity and Poverty. By Sefa Awawory Churchill, Russell Smyth

Highlights

.  We examine the relationship between ethnic diversity and poverty.
.  We measure poverty using a wide range of indicators from the World Bank and UNDP. Ethnic diversity is measured by both fractionalization and polarization.
.  Ethnic diversity increases poverty.

Summary: We examine the relationship between ethnic diversity and poverty for a cross-sectional sample of developing countries. We measure diversity using indices of ethnic and linguistic fractionalization, and measure poverty using the multidimensional poverty index (MPI), multidimensional poverty headcount (MPH), intensity of deprivation, poverty gap, and poverty headcount ratio. We find that ethnic and linguistic fractionalization contributes to poverty levels. Specifically, after controlling for endogeneity, we find that a standard deviation increase in ethnic fractionalization is associated with a 0.32-, 0.44- and 0.53-standard deviation increase in the MPI, MPH and the intensity of deprivation, respectively. Moreover, a standard deviation increase in ethnic fractionalization is associated with between a 0.34- and 0.63-standard deviation increase in the population living below $1.90 and $3.10, the poverty gap at $1.90 and $3.10 a day and the headcount ratio at $1.90 and $3.10 a day. Similar results are also observed for linguistic fractionalization with standardized coefficients between 0.53 and 0.93. We find that our results are robust to alternative ways to measure poverty and ethnic diversity including ethnic polarization as well as alternative approaches to address endogeneity.

The Effect of Income on Subjective Well-Being: Evidence from the 2008 Economic Stimulus Tax Rebates

The Effect of Income on Subjective Well-Being: Evidence from the 2008 Economic Stimulus Tax Rebates. By Marta Lachowska. In Journal of Human Resources, Oct 2015
https://papers.ssrn.com/sol3/papers.cfm?abstract_id=2682543##

Abstract: This paper uses tax rebate payments from the 2008 economic stimulus to estimate the effect of a one-time change in income on three measures of subjective well-being: life satisfaction, health satisfaction, and affect. The income effect is identified by exploiting the plausibly exogenous variation in the payment schedule of the rebates. Using both ordinary least squares and two-stage least squares estimators, I find that the rebates had a large and positive impact on affect, which is explained by a reduction in feelings of stress and worry. For life satisfaction and health satisfaction, there is weaker evidence of a positive impact. Overall, the results show that a temporary increase in liquidity may enhance emotional well-being and that this effect is relatively stronger for low-income respondents.

On the Size of the Gender Difference in Competitiveness

On the Size of the Gender Difference in Competitiveness. By Silvia Saccardo, Aniela Pietrasz, Uri Gneezy. In Management Science, http://dx.doi.org/10.1287/mnsc.2016.2673

Abstract: We design a new procedure for measuring competitiveness and use it to estimate the magnitude of the gender gap in competitiveness. Before working on a task, participants choose what percentage of their payoffs will be based on a piece-rate compensation scheme; the rest of their payoff is allocated to a competitive compensation scheme. This novel procedure allows us to distinguish between 101 levels of competitiveness, as opposed to the binary measure used in the literature. Whereas the binary measure allows researchers to conclude that about twice as many men as women choose to compete (typically two-thirds versus one-third), the new procedure sheds light on the intensive margin. We find that the intensity of the preference is more extreme than the binary measure could detect. For example, we find that only one-fifth of the most competitive 25% of our participants are women, and the most competitive 10% of our participants are all men. The new procedure also allows us to study the correlation between competitiveness and parameters such as overconfidence, attitudes toward risk, and ambiguity.

Perceived warmth and competence of others shape voluntary deceptive behaviour

Perceived warmth and competence of others shape voluntary deceptive behaviour in a morally relevant setting. Br J Psychol. 2017 Mar 9. doi: 10.1111/bjop.12245. By Azevedo RT, Panasiti MS, Maglio R, Aglioti SM.

Abstract: The temptation to deceive others compares to a moral dilemma: it involves a conflict between the temptation to obtain some benefit and the desire to conform to personal and social moral norms or avoid aversive social consequences. Thus, people might feel different levels of emotional and moral conflict depending on the target of the deception. Here we explored, in a morally relevant setting, how social judgements based on two fundamental dimensions of human social cognition - 'warmth' and 'competence' - impact on the decision to deceive others. Results revealed independent effects for warmth and competence. Specifically, while people are less inclined to deceive for self-gain those individuals they perceive as warm, they also tend to lie more to highly competent others. Furthermore, the perceived warmth and competence modulated the general tendency to reduce deceptive behaviour when there was a risk of disclosure compared to when the lying was anonymous, highlighting the importance of these judgements in social evaluation processes. Together, our results demonstrate that the emotional costs and personal moral standards that inhibit engagement in deceptive behaviour are not stable but rather malleable according to the target and the consequences of the deception.

Do Globalization and Free Markets Drive Obesity among Children and Youth? An Empirical Analysis, 1990–2013

Do Globalization and Free Markets Drive Obesity among Children and Youth? An Empirical Analysis, 1990–2013
http://www.tandfonline.com/doi/abs/10.1080/03050629.2017.1311259?journalCode=gini20&

ABSTRACT: Scholars of public health identify globalization as a major cause of obesity. Free markets are blamed for spreading high calorie, nutrient-poor diets, and sedentary lifestyles across the globe. Global trade and investment agreements apparently curtail government action in the interest of public health. Globalization is also blamed for raising income inequality and social insecurities, which contribute to “obesogenic” environments. Contrary to recent empirical studies, this study demonstrates that globalization and several component parts, such as trade openness, FDI flows, and an index of economic freedom, reduce weight gain and obesity among children and youth, the most likely age cohort to be affected by the past three decades of globalization and attendant lifestyle changes. The results suggest strongly that local-level factors possibly matter much more than do global-level factors for explaining why some people remain thin and others put on weight. The proposition that globalization is homogenizing cultures across the globe in terms of diets and lifestyles is possibly exaggerated. The results support the proposition that globalized countries prioritize health because of the importance of labor productivity and human capital due to heightened market competition, ceteris paribus, even if rising incomes might drive high consumption.
