The reform and opening up policy,which was adopted in China more than two decades ago,has largely torn down the barriers preventing rural residents from moving into cities,resulting in a rapid influx of surplus rural laborers into the cities.The fifth nat…     

Happiness Inequality: How Much is Reasonable?

We compute the Gini indexes for income, happiness and various simulated utility levels. Due to decreasing marginal utility of income, happiness inequality should be lower than income inequality. We find that happiness inequality is about half that of income inequality. To compute the utility levels we need to assume values for a key parameter that can be interpreted as a measure of relative risk aversion. If this coefficient is above one, as many economists believe, then a large part of happiness inequality is not related to pecuniary dimensions of life.     

Do You Prefer Having Much More or Slightly More than Others?

Several studies found that people have a positive utility when they have more than others do. These papers claim that individuals are willing to sacrifice part of their absolute income or products in order to have more than others. As far as we know, the current paper is the first to show that positionality is bounded, so that individuals enjoy having more than others only when the gap between them and the others is not too large. Using the results from a survey-based experiment conducted in Israel that included 924 participants, we show that when individuals were asked to forgive some of their income in order to have a higher income compared to others, most of them chose to forgive their absolute income in order to have more than others. However, when individuals were asked to forgive the same amount of income in order to a have a much higher income compared to others, the attractiveness of having more than others significantly decreased. These results may indicate that individuals suffer from a disutility when extreme gaps exist in society, even if they are the ones with the high income.     

How Much Will Feeding More and Wealthier People Encroach on Forests?

Forests have recently expanded in many countries. The success of the world, including both rich and poor, in following this trend depends on future changes in population, income per capita, appetite, and crop yields. Extended to the year 2050, the strengths of these forces, estimated from experience, project cropland shrinking by nearly 200 million hectares, more than three times the land area of France. Changes in some of the forces, with crop yield the most manageable, could double the shrinkage. Reasonable assumptions about the forces can also make the distribution of spared land between rich and poor countries roughly equal. Although the encroachment factor translating cropland change into forest land change varies greatly, one‐third or more of the cropland spared could become forest.     

Black-White Disparities in Life Expectancy: How Much Can the Standard SES Variables Explain?

This article quantifies the extent to which socioeconomic and demographic characteristics can account for black-white disparities in life expectancy in the United States. Although many studies have investigated the linkages between race, socioeconomic status, and mortality, this article is the first to measure how much of the life expectancy gap remains after differences in mortality are purged of the compositional differences in socioeconomic characteristics between blacks and whites. The decomposition is facilitated by a reweighting technique that creates counterfactual estimation samples in which the distribution of income, education, employment and occupation, marital status, and other theoretically relevant variables among blacks is made to match the distribution of these variables among whites. For males, 80% of the black-white gap in life expectancy at age 1 can be accounted for by differences in socioeconomic and demographic characteristics. For females, 70% percent of the gap is accounted for. Labor force participation, occupation, and (among women only) marital status have almost no additional power to explain the black-white disparity in life expectancy after precise measures for income and education are controlled for.     

Vaginal births after caesarean: What does Google think about it?

AimVaginal birth after caesarean (VBAC) is a relatively safe alternative to repeat caesarean birth in the proper context. This important decision to undergo an elective caesarean versus VBAC is ultimately a decision of the mother. The purpose of our study was to assess the quality of online information in relation to VBAC collected using the most common search engine: Google.MethodsThe 10 most common hit sites for the keywords “VBAC” and “Vaginal birth after caesarean” were evaluated using the search engine Google. The quality of websites was rated based on the Silberg scale for accountability, the modified Abbott's criteria for presentation and the SMOG index for readability. The content of each website was compared to the Society of Obstetricians and Gynecologists of Canada (SOGC) guidelines for VBAC.Findings13 out of 20 identified websites met the adequate criteria for accountability, with 85% of the websites indicating authorship. 11 websites were deemed aesthetically agreeable. The target audience, assessed by the readability score, was notably above the non-medical population with an average SMOG index score of 14.75. Only half of the websites contained recommendations, as detailed by the SOGC guidelines.ConclusionAlmost all sites target a higher academic level, making it beyond the comprehension of the general population. Woman friendly web-assessment tools should be provided to enable pregnant women to take an active role in their decision making.     

Poverty and Wellbeing at the ‘Grassroots’—How Much is Visible to Researchers?

This paper discusses the grassroots level understanding of poverty and wellbeing. There is rich debate and ever expanding literature on the meaning of wellbeing and poverty and their relationship in developing countries. In recent times wellbeing and poverty have been scrutinised within the discourse on multidimensionality of poverty. Most research outputs though are grounded in quantitative data. Investigations that focus on the perceptions and understandings of poor people about their situations remain sparse in the literature. The current study is an attempt to address this gap. The paper explores the common grounds and the points of departure between the researchers’ views of poverty and wellbeing and the perception at the grassroots. The paper presents findings of primary research conducted by the author in Dhar district of Madhya Pradesh and Madhubani district of Bihar in India. Semi-structured survey instruments were deployed to interview a selection of poor, marginal and non-poor households. In addition to identifying the commonalities in grassroots and researchers’ understandings of poverty, the paper draws attention to factors that may be outside the radar of the researchers. It is envisaged that mapping a more holistic understanding of poverty and wellbeing will have important long-term policy implications for poverty reduction.

What can we learn from (and about) global aging?

Although aging is a global phenomenon, there are large differences across countries in both the speed of aging and the current age composition. Furthermore, countries adopt vastly different policies. This creates a natural laboratory that scientists can use to understand how policies affect outcomes. I discuss under what circumstances data from different countries can be used for inference about policy effects. Although comparable health and retirement data are currently being collected in some 25 countries, the use of such data requires careful modeling of differences in institutions and in response styles across countries.     

Are midwifery clients in Ontario making informed choices about prenatal screening?

BackgroundInformed choice is often lacking in women's decisions about prenatal screening.AimThe aim of this study is to evaluate how well midwives in Ontario, Canada are facilitating informed choice in this area.MethodsAn Internet-based survey was used to investigate 171 midwifery clients’ knowledge, attitude towards and experience of prenatal genetic screening tests, and to determine the proportion of study participants who made an informed choice about prenatal screening.FindingsAll participants demonstrated adequate knowledge of prenatal screening. The vast majority (93.0%) of participants made an informed choice. Participants who chose to screen had lower knowledge scores than those who opted out of screening. Client satisfaction rates in regard to care received in this area ranged from 97% to 100%.ConclusionsResults of this study suggest that Ontario midwives are effective in conveying information on prenatal genetic screening, contributing to high levels of client knowledge and satisfaction in comparison to similar studies in other jurisdictions.

College students' attitudes about lesbians: what difference does 16 years make?

The article reviews empirical studies on trends in attitudes toward lesbians and gay men and compares data from a 1985 survey of 297 students living in a college residence hall with data collected in 2001 when 152 students living in the same residence hall responded to a similar questionnaire. College students in 2001 expressed more accepting attitudes toward lesbians, reported more contact with lesbians, and assessed their parents' attitudes as more positive when compared with the 1985 sample. Consistent trends in the importance of these variables to the development of attitudes toward lesbians were shown, with gender role attitudes, parental attitudes, and exposure to education and media about gays and lesbians remaining the most important predictors. This suggests that strategies that discourage gender role stereotypes and provide educational and media experiences could increase acceptance of sexual minorities. Although gender was significant in 1985, there were no effects of gender in the 2001 sample. Continued study of trends in attitudes toward all sexual minorities and attention to the relative importance of gender and gender roles are recommended.     

Predicting the Trend of Well-Being in Germany: How Much Do Comparisons, Adaptation and Sociability Matter?

Using longitudinal data from the German Socio-Economic Panel, we estimate the variation of subjective well-being experienced by Germans over the last two decades testing the role of some of the major correlates of people’s well-being. Our results suggest that the variation of Germans’ well-being between 1996 and 2007 is well predicted by changes over time of income, demographics and social capital. The increase in social capital predicts the largest positive change in subjective well-being. Income growth, also predicts a substantial change in subjective well-being, but it is compensated for about three fourths by the joint negative predictions due to income comparison and income adaptation. Finally, we find that aging of the population predicts the largest negative change in subjective well-being. This result appears to hinge on the large loss of satisfaction experienced by individuals in old age.     

Overeducation of Young Workers in Spain: How Much Does the First Job Matter? Social Indicators Research

This article contributes to recent overeducation literature on the impact of an initial education mismatch on workers’ future careers. Specifically, using the 2009 ad-hoc module of the Spanish Labour Force Survey, we quantify the differences in the probability of overeducation depending on the quality of individuals’ first match. To do this, we apply an extension of the recursive bivariate probit model, which allows potential endogeneity problems to be taken into account, as well as a dissimilar impact of the initial match for workers with different educational attainment. The results indicate that overeducation is a trap, since young workers who were mismatched in their first job are 40.2 percentage points more likely to be overeducated in a later one than those who were not. When decomposing this difference in two parts, one related to the pure effect of the initial mismatch and another one related to workers’ characteristics, we conclude that the pure effect is more important, and it depends on educational attainment.
