We investigate gender differences across multiple dimensions after 3 months of the first UK lockdown of March 2020, using an online sample of approximately 1,500 Prolific respondents’ residents in the UK. We find that women's mental health was worse than men along the four metrics we collected data on, that women were more concerned about getting and spreading the virus, and that women perceived the virus as more prevalent and lethal than men did. Women were also more likely to expect a new lockdown or virus outbreak by the end of 2020, and were more pessimistic about the contemporaneous and future state of the UK economy, as measured by their forecasted contemporaneous and future unemployment rates. We also show that between earlier in 2020 before the outbreak of the Coronavirus pandemic and June 2020, women had increased childcare and housework more than men. Neither the gender gaps in COVID-19-related health and economic concerns nor the gender gaps in the increase in hours of childcare and housework can be accounted for by a rich set of control variables. Instead, we find that the gender gap in mental health can be partially accounted for by the difference in COVID-19-related health concerns between men and women.

We assess Africa's prospects for enjoying a demographic dividend. While fertility rates and dependency ratios in Africa remain high, they have started to decline. According to UN projections, they will fall further in the coming decades such that by the mid-21st century, the ratio of the working age to dependent population will be greater than in Asia, Europe, and Northern America. This projection suggests Africa has considerable potential to enjoy a demographic dividend. Whether and when it actually materializes, and also its magnitude, hinges on policies and institutions in key realms that include macroeconomic management, human capital, trade, governance, and labor and capital markets. Given strong complementarities among these areas, coordinated policies will likely be most effective in generating the momentum needed to pull Africa's economies out of a development trap.

Before Gary Becker, fertility choice was widely considered to be outside the realm of economic analysis. Apart from intellectual tradition, one reason for this was that the data on fertility did not immediately suggest an economic mechanism. In industrialized countries, fertility had declined strongly over time, even though family incomes were rising. Similarly, in many studies using cross-sectional data the relationship between family income and fertility had been shown to be either flat or declining. To many observers, these observations suggested that the “taste” for children had waned over time and that high income families placed less value on childbearing than the poor.

The data show that an increase in government provided old-age pensions is strongly correlated with a reduction in fertility. What type of model is consistent with this finding? We explore this question using two models of fertility, the one by Barro and Becker (1989), and the one inspired by Caldwell and developed by Boldrin and Jones (2002). In the Barro and Becker model parents have children because they perceive their children’s lives as a continuation of their own. In the Boldrin and Jones’ framework parents procreate because the children care about their old parents’ utility, and thus provide them with old age transfers. The effect of increases in government provided pensions on fertility in the Barro and Becker model is very small, and inconsistent with the empirical findings. The effect on fertility in the Boldrin and Jones model is sizeable and accounts for between 55 and 65% of the observed Europe–US fertility differences both across countries and across time and over 80% of the observed variation seen in a broad cross section of countries. Another key factor affecting fertility the Boldrin and Jones model is the access to capital markets, which can account for the other half of the observed change in fertility in developed countries over the last 70 years.

We study the large observed changes in labor supply by married women in the United States over the post-World War II period, a period that saw little change in the labor supply by single women. We investigate the effects of changes in the gender wage gap, the quantitative impact of technological improvements in the production of nonmarket goods, and the potential inferiority of nonmarket goods in explaining the dramatic change in labor supply. We find that small decreases in the gender wage gap can simultaneously explain the significant increases in the average hours worked by married women and the relative constancy in the hours worked by single women and by single and married men. We also find that the impact of technological improvements in the household on married female hours and on the relative wage of females to males is too small for realistic values. Some specifications of the inferiority of home goods match the hours patterns, but they have counterfactual predictions for wages and expenditure patterns.

Recent surveys of the literature on climate change and migration emphasize the important diversity of outcomes and approaches of the empirical studies. In this paper, we conduct a meta-analysis in order to investigate the role of the methodological choices of these empirical studies in finding some particular results concerning the role of climatic factors as drivers of human mobility. We code 51 papers representative of the literature in terms of methodological approaches. This results in the coding of more than 85 variables capturing the methodology of the main dimensions of the analysis at the regression level. These dimensions include authors' reputation, type of mobility, measures of mobility, type of data, context of the study, econometric methods, and last but not least measures of the climatic factors. We look at the influence of these characteristics on the probability of finding any effect of climate change, a displacement effect, an increase in immobility, and evidence in favor of a direct vs. an indirect effect. Our results highlight the role of some important methodological choices, such as the frequency of the data on mobility, the level of development, the measures of human mobility and of the climatic factors as well as the econometric methodology.

Migrant networks play an important role in explaining the size and structure of migration flows. They affect the private costs and benefits of migration (assimilation channel) and lower legal entry barriers through family reunification programs (policy channel). This paper presents a micro-founded identification strategy allowing to disentangle the relative importance of these two channels. Our empirical analysis exploits US immigration data by metropolitan area and country of origin. We first find that the elasticity of migration flows to network size is around one. More interestingly, we show that the policy channel accounted at most for a quarter of this elasticity in the 1990s, and the magnitudes of the total network effect and the policy channel are greater for low-skilled migrants. Our results are strongly robust to sample selection, identification assumptions, and treatment for unobserved bilateral heterogeneity. Furthermore, the policy channel was stronger in the 1990s than in the 1980s, possibly reflecting the changes in the US family reunification policies. We conclude that the government capacity to curb the migration multiplier exists, but is limited.

The Integrated Public Use Microdata Series (IPUMS)-International partnership is a project of the Minnesota Population Center and national statistical agencies, dedicated to collecting and distributing census data from around the world. IPUMS is currently disseminating data on over a half-billion persons enumerated in more than 250 census samples from 79 countries. The data series includes information on a broad range of population characteristics, including fertility, nuptiality, life-course transitions, migration, labor-force participation, occupational structure, education, ethnicity, and household composition. This paper describes sample characteristics and data structure; the data integration process including the creation of constructed family interrelationship variables; the flexible dissemination system that enables researchers to build customized extracts of pooled census samples across time and place; and some of the most significant findings that have emerged from the database.

Life expectancy at birth has more than doubled in Europe since the early 19th century. This demographic trend constitutes a major victory against scarcity, but raises also deep challenges to the Welfare State, concerning the sustainability and the equity of the social protection system. This paper surveys recent developments in the economic analysis of longevity, both at the positive and the normative levels. Taking mortality risks into account is shown to affect the study of the life cycle model significantly, in particular concerning the strength of life horizon effects. It raises also, at the level of normative foundations for policy-making, a dilemma between ex ante and ex post valuations. Finally, we explore the design of policy reforms under varying longevity, in fields including preventive and curative policies, education, pension, and wealth taxation.

We use data from Sierra Leone where a substantial education program provided increased access to education for primary-school age children but did not benefit children who were older. We exploit the variation in access to the program generated by date of birth and the variation in resources between various districts of the country. We find that an increase in schooling, triggered by the program, has an impact on women's attitudes toward matters that impact women's health and on attitudes regarding violence against women. An increase in education reduces the number of desired children by women and increases their propensity to use modern contraception and to be tested for AIDS. While education makes women more intolerant of practices that conflict with their well-being, increased education has no impact on men's attitudes toward women's well-being. Thus, it is unclear whether the change in attitudes would translate into behavioral changes. Consistent with this finding, education (on this margin) has no impact on women's propensity to get married, their age at first marriage or age at first birth.

This paper produces new estimates for white and black mortality and fertility at the state level from 1800(20)–2000. It produces new estimates of black and white schooling for this same period. Using a calibrated model of black and white parents, we fit the time series of black and white fertility and schooling. We then produce estimates of the benefits of equal education opportunity for blacks over the period 1820–2000. For the better part of US history, blacks have suffered from less access to schooling for their children than whites. This paper quantifies the magnitude of this discrimination. Our estimates of the welfare cost of this discrimination prior to the Civil War range between 0.5 and 20 times black wealth, and between 0.5 and 10 times black wealth prior to 1960. Further we find that the Civil Rights era was valued by blacks in the South by between 1% to 2% of wealth. Outside of the South, we find significant costs of discrimination prior to 1960, ranging from 6% to 150% of black wealth. For these divisions from 1960–2000, blacks have attained rough parity in schooling access. The welfare magnitudes are similar to the hypothetical gains to blacks if they had white mortality rates. We show that the model’s black and white human capital series are strongly, positively correlated with state output measures, black and white permanent incomes and black and white earnings.

The majority of the urban population of Sub-Saharan Africa lives in slums where access to basic services, such as water, sanitation, or electricity is low. There is a growing body of evidence showing that access to these basic services has significant effect on the well-being of the poor. As the progress to universal access is still very slow, this essay contributes to the understanding of the persistence of the situation by reviewing the recent empirical evidence on both supply and demand issues related to the provision of basic infrastructure in urban areas of developing countries.

The most common measure of reproductive behavior is the total fertility rate, which measures children born per woman. However, little work exists measuring male fertility behavior. We use survey data from several waves of the Demographic and Health Surveys (DHS) in eight Sub-Saharan African countries. We document several interesting differences in fertility outcomes of men and women. First, comparing completed fertility by birth cohorts, we find that on average men have more children than women in seven out of eight countries we consider. The gaps are large – reaching up to 4.6 children in Burkina Faso. Positive gaps are possible when populations are growing and men father children with younger women. Such a situation often coincides with polygyny. Indeed, we find that the fertility gap is positively related to the degree of polygyny. Second, we find a lower variance in completed fertility rates for women than for men, especially in high polygyny countries. Third, we find that differences in the desire to have children can largely be explained by differences in realized fertility. Finally, we find that for men, the demographic transition started earlier and was steeper than for women. These novel facts are useful when building theories of fertility behavior.

We are among the first to use American time-use data to investigate non-market behavior in gay and lesbian households. We contribute to a literature that has documented a gay disadvantage and lesbian advantage in the labor market. Many have proposed that this pattern reflects, relative to their heterosexual counterparts, higher levels of household labor among gay men and lower levels of household labor among lesbian women. Results show that gay men, parents in particular, spend more time in household production than heterosexual men. We find evidence of different time-use patterns for lesbians, but they are driven by characteristics not sexual orientation. These results also contribute to the economics of the household showing that time use in same-sex households with weaker gender constructs does not conform to the predictions of models that highlight comparative advantage as a source of specialization.

We reconsider the well-known Becker–Coase (BC) theorem according to which changes in divorce law should not affect divorce rates. We do that in a context of households that consume public goods in addition to private goods. For the Becker–Coase theorem to hold in this setting, utility must be transferable both within marriage and upon divorce, and the marginal rate of substitution between public and private consumption needs to be invariant in marital status. We show that if divorce alters the way some goods are consumed (either because some goods that are public in marriage become private in divorce or because divorce affects either the marginal rate of substitution between public and private goods or even the cardinalization of a spouse’s utility), then the Becker–Coase theorem holds only for very specific preferences. We conclude that, in general, divorce laws will influence the divorce rate, although the impact of a change in divorce laws can go in either direction.

We hereby present a dataset produced at the Wittgenstein Centre (WIC) containing comprehensive time series on educational attainment and mean years of schooling (MYS). The dataset is split by 5-year age groups and sex for 171 countries and covers the period between 1970 and 2010. It also contains projections of educational attainment to 2060 based on several scenarios of demographic and educational development. The dataset is constructed around collected and harmonized empirical census and survey data sets for the projection base year. The paper presents the principles and methodology associated with the reconstruction and the projection, and how it differs from several previous exercises. It also proposes a closer look at the diffusion of education in world regions and how the existing gaps in terms of generation, gender, and geography have been evolving in the last 40 years.

This paper provides a closed-form solution for the health capital model of health demand. The results are exploited in order to prove analytically the comparative dynamics of the model. Results are derived for the so-called pure investment model, the pure consumption model and a combination of both types of models. Given the plausible assumptions that (i) health declines with age and that (ii) the health capital stock at death is lower than the health capital stock needed for eternal life, it is shown that the optimal solution implies eternal life.

The stylized facts of Africa's urban transition highlight the limitations of traditional economic models of urbanization. Recent research has provided evidence that demographic rather than economic processes provide a more compelling explanation for observed trends in the region. In particular, mortality decline appears to be both a necessary and sufficient condition for urbanization to occur and a key driver of urban growth more broadly. The accumulation of survey data over the past few decades and the development of new geospatial datasets that incorporate satellite imagery are facilitating new, more spatially nuanced insights into the dynamics of urban population change in the region. This offers opportunity to develop better policies for managing urban change than those adopted in the past, which placed a misguided emphasis on manipulating migration incentives with little evidence of positive benefits.

This article provides a comprehensive picture of the National Transfer Accounts (NTA), a project that aims at measuring how people produce, consume, save, and share economic resources at every age. It stands today with a unique dataset that includes 47 countries from around the world, permitting a comparative understanding of economic flows within and between generations and over time.

This paper investigates the long-term impact of historical missionary activity on HIV in sub-Saharan Africa. On the one hand, missionaries were the first to invest in modern medicine in the region. On the other hand, Christianity influenced sexual beliefs and behaviors that affect the risk of contagion. We build a new geocoded dataset locating Protestant and Catholic missions in the early 20th century, as well as the health facilities they invested in, that we combine with individual-level Demographic and Health Survey data. With these data, we can address separately these two channels, within regions close to historical missionary settlements. First, we show that proximity to historical missionary health facilities decreases the likelihood of HIV; persistence in healthcare provision and safer sexual behaviors in the region explain this result. Second, we show that regions close to historical missionary settlements exhibit higher likelihood of HIV. This effect is driven by the Christian population in our sample. This suggests conversion to Christianity as a possible explanatory channel. Our findings are robust to alternative specifications addressing selection.
