How does household production affect measured income inequality?

Theory predicts that lower-income households will produce more goods at home. Thus extended income, which includes household production, should be more equally distributed than money income. Previous studies have confirmed the greater equality of extended income and speculated that the result is due to the weak correlation between money income and household production. We also confirm this result and identify the true reason. We show that the weak correlation cannot be the explanation and that virtually all of the difference in measured inequality between the two measures is due to the addition of a large constant—the average value of household production—to money income.     

Does welfare reform affect fertility? Evidence from the UK

This paper provides evidence on the effect of welfare reform on fertility, focusing on UK reforms in 1999 that increased per-child spending by 50% in real terms. We use a difference-in-differences approach, exploiting the fact that the reforms were targeted at low-income households. The reforms were likely to differentially affect the fertility of women in couples and single women because of the opportunity cost effects of the welfare-to-work element. We find no increase in births among single women, but evidence to support an increase in births (by around 15%) among coupled women.     

Does child gender affect marital status? Evidence from Australia

Pooling microdata from five Australian censuses, I explore the relationship between child gender and parents’ marital status. By contrast with the USA, I find no evidence that the gender of the first child has a significant impact on the decision to marry or divorce. However, among two-child families, parents with two children of the same sex are 1.7 percentage points less likely to be married than parents with a boy and a girl. This finding is unlikely to be consistent with theories of preference for sons over daughters, differential costs, role models, or complementary costs but is consistent with a theory of mixed-gender preference.

Why does migration decrease fertility? Evidence from the Philippines

We model the impact of past migration on fertility, assessing the separate effects of relative urbanization of the destination, as a proxy for norms, and post-migration employment, as a proxy for opportunity costs. In the Philippines, we find that large fertility declines accompany post-migration employment. If not followed by work for pay, the estimated fertility impact of migration is small. We find little evidence of migrant selectivity in fertility, and offer speculative evidence that fertility disruption accompanying migration may be large enough to account for much of the apparent effect of normative adaptation.     

Do fundraisers select charitable donors based on gender and race? Evidence from survey data

Recent studies document that people are much more likely to donate to charity and volunteer their time when they are asked to. Using household surveys of giving and volunteering in the United States conducted from 1992 to 2001, which contain questions on whether the respondent was personally asked to give or volunteer, this paper investigates the factors associated with the probability of receiving a charitable solicitation and presents substantial evidence that race and gender differences play key roles in the selection of potential donors. In particular, males, blacks, and Hispanics are less likely to be solicited compared with females and whites. Using non-linear decomposition techniques, I find that differences in observable characteristics of individuals explain most of the racial gap in the probability of being solicited for charitable causes, but they fail to explain the gender gap in the probability of being asked to volunteer. Furthermore, these results are robust to alternative specifications. I also discuss related policy implications and argue that the economic impact of selecting potential donors based on gender and race can be considerable.

Can indigenous transborder migrants affect environmental governance in their communities of origin? Evidence from Mexico

Despite high rates of out-migration, Mexican indigenous communities play a crucial role in biodiversity conservation. However, little is known about migrants’ role in environmental management. This research brief explores the case of the Purépecha of San Pedro Ocumicho, Michoacán, and its transborder community in the Coachella Valley of California. We find that migrants maintain strong cultural ties to their community of origin. However, many are undocumented, are unable to access steady and well-paid employment, and would be unable to return to California were they to visit Mexico. Furthermore, government structures in Ocumicho are weak, providing few opportunities for migrants to contribute. These factors currently preclude migrants from influencing environmental decision making in their home community. Our findings point to the need for more comprehensive and longitudinal studies to better document and explain the variations in migrant support for environmental governance in their communities of origin.     

Does the marriage market sex ratio affect parental sex selection? Evidence from the Chinese census

Recent increases in the (male/female) sex ratio at birth in eastern Asia are thought to be associated with a preference for sons and to result from parental sex selection. However, males are less likely to marry and to have offspring as the ratio increases, and that decreases the expected number of grandchildren. Using data from the 2000 Chinese census, we test whether the sex ratio in the marriage market has an effect on the gender of subsequent births and hence on the sex ratio of the birth cohort. The slow population growth caused by the Great Famine in the early 1960s and the quick recovery that followed produced major changes in the sex ratio for those of marriageable age two decades later. We estimate that an increase of 1 % in the number of marriageable males relative to females, the marriage market sex ratio, would decrease the probability of having a son by 0.02 percentage points. That implies that the Great Famine, which occurred around 1960, led to an increase in the early 1980s of 5.8 extra male births per 100 females.     

Does crop diversity at the village level influence child nutrition security? Evidence from 11 sub-Saharan African countries

Population and Environment - Diversifying crop production has been proposed as a means of reducing food and nutrition insecurity in sub-Saharan Africa, but previous empirical studies yield mixed...     

Are parents altruistic? Evidence from Mexico

Are parents altruistic or selfish? We contribute to the continuing debate of this question by proposing a simple test which is implemented using experimental data from the Mexican anti-poverty programme PROGRESA. Benefit eligibility is randomised. Our estimation strategy explicitly addresses potentially confounding factors and selection bias problems. We reject selfishness of parents in non-urban Mexico as PROGRESA beneficiaries spend more on child-related goods and do not increase spending on adult-related goods compared to parents in the control group. At the same time, we reject some rival theories.     

Do household structure and household economic resources predict childhood immunization? Evidence from Jamaica and Trinidad and Tobago

This study assesses the influence of household structure and resource dilution characteristics on childrens immunization coverage in Jamaica and Trinidad and Tobago. The study has three objectives: (1) to compare the impact of different types of household structures (e.g., single parent, two-parent, cohabiting and extended) on child immunization; (2) to examine the effects of household income and resource dilution on child immunization; and (3) to determine whether household structure and resource dilution interact to affect child immunization in these contexts.We use data from the Jamaica 1996 and Trinidad and Tobago 1997 Living Standards Measurement Study Survey and a series of logistic regression models to test hypotheses derived from the current child well-being literature. The results show that household income and household structures selectively predict childrens immunization coverage in both contexts, with significant interaction effects enhancing the interpretation for Jamaica. The key policy implications that emerge from this study are that household structure and income are crucial for understanding child immunization in the Caribbean.     

Social security, economic growth, and the rise in elderly widows’ independence in the twentieth century

The percentage of elderly widows living alone rose from 18% in 1940 to 62% in 1990, while the percentage living with adult children declined from 59% to 20%. This study finds that income growth, particularly increased Social Security benefits, was the single most important determinant of living arrangements, accounting for nearly one-half of the increase in independent living. Unlike researchers in earlier studies, we find no evidence that the effect of income become stronger over the period. Changes in age, race, immigrant status, schooling, and completed fertility explain a relatively small share of the changes in living arrangements.     

Women's adjustment to widowhood: does social support matter?

Widowhood is a stressful event for women, often coinciding with health, financial, and relationship losses. Researchers have considered many aspects of women's adjustment to widowhood, typically including social support in analyses. This study analyzed relationships between social support and adjustment from 19 previous widowhood studies. Contrary to intuition and most researchers' assumptions, the majority of relationships did not show that social support positively impacted adjustment. Analyses examined whether type of support or study methods affected the likelihood of finding a significant relationship between support and adjustment. Chi-square statistics indicated that neither of these factors influenced the effect of social support on women's adjustment to widowhood.     

Does How You Measure Income Make a Difference to Measuring Poverty? Evidence from the UK

Income is regarded as one of the clearest indicators of socioeconomic status and wellbeing in the developed world and is highly correlated with a wide range of outcomes. Despite its importance, there remains an issue as to the best way to collect income as part of surveys. This paper examines differences in how income is collected in a nationally representative UK birth cohort, the Millennium Cohort Study, looking at variations by questions asked and by respondent characteristics before then examining the implications different methods of collecting and reporting income may have for measuring poverty. Results show that less than a third of respondents give consistent information on income between measurement tools. Using multiple questions is associated with a substantially lower response rate but this method generally results in a higher estimate of family income than using a single question. This is particularly true for certain groups of the population—those on means tested benefits, in self-employment and in part-time employment. Not surprisingly then in our analysis of poverty, using a single question produces an inflated proportion of families who could be classified as living in poverty and is less associated with other measures of financial deprivation than the more conservative poverty measure based on multiple questions.     

Does the number of sex partners affect educational attainment? Evidence from female respondents to the Add Health

We use data on young women from the National Longitudinal Study of Adolescent Health to explore the relationship between number of sex partners and educational attainment. Using the average physical development of male schoolmates to generate plausibly exogenous variation in number of sex partners, instrumental variables estimates suggest that number of sex partners is negatively related to educational attainment. This result is consistent with the argument that romantic involvements are time consuming and can impose substantial emotional costs on young women.     

Population growth and optimality: when does serendipity hold?

This note gives the conditions under which there is an interior optimum rate of population growth in a two-generations-overlapping model. These conditions imply complementarity both in production and in consumption. They also validate Samuelson's serendipity theorem.
