When Children Rule: Parenting in Modern Families

When Children Rule: Parenting in Modern Families. By Sebastian Galiani, Matthew Staiger, Gustavo Torrens
NBER Working Paper No. 23087
http://www.nber.org/papers/w23087
NBER Program(s):   ED

During the 20th century there was a secular transformation within American families from a household dominated by the father to a more egalitarian one in which the wife and the children have been empowered. This transformation coincided with two major economic and demographic changes, namely the increase in economic opportunities for women and a decline in family size. To explain the connection between these trends and the transformation in family relationships we develop a novel model of parenting styles that highlights the importance of competition within the family. The key intuition is that the rise in relative earnings of wives increased competition between spouses for the love and affection of their children while the decline in family size reduced competition between children for resources from their parents. The combined effect has empowered children within the household and allowed them to capture an increasing share of the household surplus over the past hundred years

Pregnancy leads to long-lasting changes in human brain structure

Pregnancy leads to long-lasting changes in human brain structure. By Elseline Hoekzema et al.
Nature Neuroscience
http://www.nature.com/neuro/journal/v20/n2/full/nn.4458.html

Abstract: Pregnancy involves radical hormone surges and biological adaptations. However, the effects of pregnancy on the human brain are virtually unknown. Here we show, using a prospective ('pre'-'post' pregnancy) study involving first-time mothers and fathers and nulliparous control groups, that pregnancy renders substantial changes in brain structure, primarily reductions in gray matter (GM) volume in regions subserving social cognition. The changes were selective for the mothers and highly consistent, correctly classifying all women as having undergone pregnancy or not in-between sessions. Interestingly, the volume reductions showed a substantial overlap with brain regions responding to the women's babies postpartum. Furthermore, the GM volume changes of pregnancy predicted measures of postpartum maternal attachment, suggestive of an adaptive process serving the transition into motherhood. Another follow-up session showed that the GM reductions endured for at least 2 years post-pregnancy. Our data provide the first evidence that pregnancy confers long-lasting changes in a woman's brain.

A Virtual Out-of-Body Experience Reduces Fear of Death

A Virtual Out-of-Body Experience Reduces Fear of Death. By Pierre Bourdin et al.
http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0169343
PLoS ONE, January 2017

Abstract: Immersive virtual reality can be used to visually substitute a person’s real body by a life-sized virtual body (VB) that is seen from first person perspective. Using real-time motion capture the VB can be programmed to move synchronously with the real body (visuomotor synchrony), and also virtual objects seen to strike the VB can be felt through corresponding vibrotactile stimulation on the actual body (visuotactile synchrony). This setup typically gives rise to a strong perceptual illusion of ownership over the VB. When the viewpoint is lifted up and out of the VB so that it is seen below this may result in an out-of-body experience (OBE). In a two-factor between-groups experiment with 16 female participants per group we tested how fear of death might be influenced by two different methods for producing an OBE. In an initial embodiment phase where both groups experienced the same multisensory stimuli there was a strong feeling of body ownership. Then the viewpoint was lifted up and behind the VB. In the experimental group once the viewpoint was out of the VB there was no further connection with it (no visuomotor or visuotactile synchrony). In a control condition, although the viewpoint was in the identical place as in the experimental group, visuomotor and visuotactile synchrony continued. While both groups reported high scores on a question about their OBE illusion, the experimental group had a greater feeling of disownership towards the VB below compared to the control group, in line with previous findings. Fear of death in the experimental group was found to be lower than in the control group. This is in line with previous reports that naturally occurring OBEs are often associated with enhanced belief in life after death.

Political Persecutions and Social Capital: Evidence from Imperial China

Autocratic Rule and Social Capital: Evidence from Imperial China. Melanie Meng Xue, Mark  Koyama
November 30, 2016. GMU Working Paper in Economics No. 16-50. https://papers.ssrn.com/sol3/papers.cfm?abstract_id=2856803

Abstract:     This paper studies the consequences of autocratic rule for social capital in the context of imperial China. Between 1660-1788, individuals were persecuted if they were suspected of subversive attitudes towards the autocratic ruler.   Using a difference-in-differences approach, our main finding is  that these persecutions led to an average decline of 38% in the number of charitable organizations in each subsequent decade.

To investigate the long-run effect of persecutions, we examine the impact that they had on the provision of local public goods.  During this period,  local public goods, such as basic education, relied primarily on voluntary contributions and local cooperation.   We show that persecutions are associated with lower provision of basic education suggesting that they permanently reduced social capital. This is consistent with what we  find in modern survey data:  persecutions left a legacy of mistrust and political apathy.

Insurance policy specifically for self-inflicted liver damage

China’s Zhongan sees scope for offbeat insurance.
https://www.ft.com/content/bee51a52-accd-11e6-9cb3-bb8207902122
Financial Times
Medical insurance often becomes invalid if the customer is drunk. But during the football World Cup in 2014, Shanghai-based Zhongan Insurance turned that rule upside down by offering Chinese football fans a policy specifically for self-inflicted liver damage.

It cost less than $1 and covered sports enthusiasts against alcohol poisoning for 30 days — paying out up to Rmb2,000 ($290) for hospital fees. It soon came to be known as “watching-football-drinking-too-much” insurance.

This has not been Zhongan’s only foray into more specialist areas of China’s insurancemarket. Another of its policies, called “high heat”, reimburses customers when the temperature hits 37°C. Another insures against flight delays — and, in many cases, pays out while the customer is still waiting in the departure lounge.

Zhongan has sold 5800m policies to 460m customers. This has quickly translated into profit.

Upward Mobility and Discrimination: The Case of Asian Americans

Upward Mobility and Discrimination: The Case of Asian Americans. By Nathaniel Hilger
NBER Working Paper No. 22748
October 2016
NBER Program(s):   LS
http://www.nber.org/papers/w22748

Asian Americans are the only non-white US racial group to experience long-term, institutional discrimination and subsequently exhibit high income. I re-examine this puzzle in California, where most Asians settled historically. Asians achieved extraordinary upward mobility relative to blacks and whites for every cohort born in California since 1920. This mobility stemmed primarily from gains in earnings conditional on education, rather than unusual educational mobility. Historical test score and prejudice data suggest low initial earnings for Asians, unlike blacks, reflected prejudice rather than skills. Post-war declines in discrimination interacting with previously uncompensated skills can account for Asians’ extraordinary upward mobility.

Sabotage occurs more often when Green Party candidates fail to win even minor offices

The political roots of domestic environmental sabotage
Benjamin Farrer & Graig Klein
Journal of Elections, Public Opinion and Parties,

Volume 27, 2017 - Issue 2

http://www.tandfonline.com/doi/abs/10.1080/17457289.2016.1247846

Abstract: In this paper, we demonstrate that when environmentalist niche parties compete in a given constituency over a number of elections, but continually fail to win seats, then environmental sabotage becomes more frequent in that constituency. When mainstream tactics fail, radical tactics are used more frequently. Using a new data-set on the success rates of all Green Party candidates in US states, we show that environmental sabotage occurs more often when Green Party candidates fail to win even minor offices. This is true even when we control for other political expressions of environmentalism, such as interest group activity, and when we define ‘success’ through votes not seats. We discuss the implications of this for environmental politics, for social movements and democracy, and for political violence in the US.

Children of low-income parents are much less likely to become inventors than their higher-income counterparts

The Lifecycle of Inventors, by Alex Bell et al.
Harvard Working Paper, June 2016
https://papers.ssrn.com/sol3/papers.cfm?abstract_id=2838018

Abstract: We use administrative records on the population of individuals who applied for or were granted a patent between 1996 and 2014 to characterize the lives of more than 1.2 million inventors in the United States. We show that children of low-income parents are much less likely to become inventors than their higher-income counterparts (as are minorities and women). Decompositions using third grade and older test scores indicate that this income-innovation gap can largely be accounted for by differences in human capital acquisition while children are growing up. We establish the importance of "innovation exposure effects" during childhood by showing that growing up in an area with a high innovation rate in a particular technology class is associated with a much higher probability of becoming an inventor specifically in that technology class. Similarly, exposure to innovation from parents or their colleagues in specific fields is also associated with greater future innovation by children in those same technological fields. Inventors' incomes are very skewed and uncertain at the start of their career. While our analysis does not directly identify the causal mechanisms that drive innovation, our descriptive findings shed light on which types of policy tools are likely to be most effective in sparking innovation. Calibrations suggest that "extensive margin" policies drawing more talented children from low-income families into the R&D sector have great potential to improve aggregate innovation rates.

Relationship between spicy food and aggressive cognition

You are what you eat: An empirical investigation of the relationship between spicy food and aggressive cognition. By Rishtee K. Batra, Tanuka Ghoshal, Rajagopal Raghunathan
http://www.sciencedirect.com/science/article/pii/S0022103116303389

Abstract: The popular saying “you are what you eat” suggests that people take on the characteristics of the food they eat. Wisdom from ancient texts and practitioners of alternative medicine seem to share the intuition that consuming spicy food may increase aggression. However, this relationship has not been empirically tested. In this research, we posit that those who consume “hot” and “spicy” food may be more prone to thoughts related to aggression. Across three studies, we find evidence for this proposition. Study 1 reveals that those who typically consume spicy food exhibit higher levels of trait aggression. Studies 2 and 3 reveal, respectively, that consumption of, and even mere exposure to spicy food, can semantically activate concepts related to aggression as well as lead to higher levels of perceived aggressive intent in others. Our work contributes to the literature on precursors of aggression, and has substantive implications for several stakeholders, including marketers, parents and policy makers.

Determinants of financial outcomes and choices: the role of noncognitive abilities

Understanding the determinants of financial outcomes and choices: the role of noncognitive abilities, Gianpaolo Parise and Kim Peijnenburg
BIS Working Papers No 640. May 2017
http://www.bis.org/publ/work640.htm

We explore how financial distress and choices are affected by noncognitive abilities. Our measures stem from research in psychology and economics. In a representative panel of households, we find that people in the bottom decile of noncognitive abilities are five times more likely to experience financial distress compared to those in the top decile. Relatedly, individuals with lower noncognitive abilities make financial choices that increase their likelihood of distress: They are less likely to plan for retirement and save, and more likely to buy impulsively and to have unsecured debt. Causality is shown using childhood trauma as an instrument.

Our social evaluation of other people is influenced by their faces and their voices. How?

Audiovisual Integration in Social Evaluation. By Mila Mileva et al.
Journal of Experimental Psychology: Human Perception and Performance, in press
http://eprints.whiterose.ac.uk/116201/1/MTWB_Audioviusual_author_version.pdf

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
https://doi.org/10.1016/j.worlddev.2017.02.032
World Development, Volume 95, July 2017, Pages 285–302

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.

Key words: ethnic diversity; poverty; fractionalization; polarization

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.
https://www.ncbi.nlm.nih.gov/pubmed/28276063

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.

Small association between socioeconomic status and adult fast-food consumption in US

The association between socioeconomic status and adult fast-food consumption in the U.S. By Jay L. Zagorsky , Patricia K. Smith. Economics & Human Biology
http://www.sciencedirect.com/science/article/pii/S1570677X16300363

Highlights
•   Fast-food consumption among adults varies little across SES, measured as income and wealth.
•   Descriptive analyses indicate a weak, inverted U-shaped association between fast-food and SES.
•   Checking nutrition labels frequently and drinking less soda predict less adult fast-food intake.
•    More work hours predict greater fast-food intake.

Abstract: Health follows a socioeconomic status (SES) gradient in developed countries, with disease prevalence falling as SES rises. This pattern is partially attributed to differences in nutritional intake, with the poor eating the least healthy diets. This paper examines whether there is an SES gradient in one specific aspect of nutrition: fast-food consumption. Fast food is generally high in calories and low in nutrients. We use data from the 2008, 2010, and 2012 waves of the National Longitudinal Survey of Youth (NLSY79) to test whether adult fast-food consumption in the United States falls as monetary resources rise (n = 8136). This research uses more recent data than previous fast-food studies and includes a comprehensive measure of wealth in addition to income to measure SES.

Protestant Ethic and Entrepreneurship: Religious Minorities in the Holy Roman Empire

The Protestant Ethic and Entrepreneurship:  Evidence from Religious Minorities in the Former Holy Roman Empire.  By Luca Nunziata, Lorenzo Rocco. European Journal of Political Economy
https://doi.org/10.1016/j.ejpoleco.2017.04.001

Abstract: We investigate the effect of Protestantism versus Catholicism on the decision to become an entrepreneur in former Holy Roman Empire regions. Our research design exploits religious minorities' strong attachment to religious ethic and the predetermined historical determination of religious minorities' geographical distribution in the 1500 s as a result of the “cuius regio eius religio” (whose realm, his religion) rule. We find that today Protestantism increases the probability to be an entrepreneur by around 5 percentage points with respect to Catholicism, a result that survives to a battery of robustness checks. We explicit the assumptions underlying the identification strategy and provide an extensive testing of their validity by making use of several European datasets.
