Iron toxicity is one of the constraints limiting rice production in Africa. This study used a randomized controlled trial to assess the impact of an iron toxicity-tolerant variety, named ARICA 6, on different outcomes and investment in modern inputs by smallholder farmers. Two rounds of data were collected from 520 rice-farming households in Guinea. Results showed that the use of ARICA 6 increased rice yield by 330 kg ha−1 and net income by US$ 120 ha−1. However, adoption of improved variety may not be enough to crowd in investment in modern inputs because farmers face other constraints.

In Africa, rangeland ecosystems have been exploited due to heavy and unsustainable grazing. Policy and institutional mechanisms such as integrating silvopastoral systems with sustainable grazing practices have been devised to mitigate the negative effects. In this study, we investigated whether the uptake of sustainable grazing management in the form of controlled grazing spurs investment in multipurpose trees (MPTs) and enhances income. Using instrumental variable regression, we find that controlled grazing increases not only the propensity to plant MPTs but also the number of tree species. More importantly, IV and treatment effect results indicate that controlled grazing enhances income from MPTs.

This study examines the impact of the row planting method on maize productivity and risk exposure using panel datasets from Ethiopia. A flexible moment-based production function is fitted to capture the expected yield, yield variance, and exposure to downside risk. A Mundlak–Chamberlain approach is combined with a switching regression treatment effects model to account for unobserved heterogeneity and endogeneity. The study shows that adopters of the row planting method significantly reduced exposure to downside risk while increasing expected yield. The analysis also identified some household and environmental conditions that affect the gain from the row planting method.

The absence of institutionalised childcare and education during the lockdowns, caused by the COVID-19 pandemic, put parents who worked from home in a stressful situation in which they had to combine the roles of teacher, parent and employee. This study aims to analyse how the closure of kindergartens and schools during the March–May 2020 lockdown in Slovenia changed the reported allocation of time, and perceived emotional exhaustion of parents working from home, compared to nonparents. We also focus on the differences in the impacts of lockdown between genders, status of family-provision and employment sectors of parents. Using data from a survey carried out on cohabiting and married individuals in Slovenia and applying a difference-in-difference estimator, we find that parents incurred a significant increase in their unpaid work burden, reductions in time devoted to paid work and leisure and suffered an increase in emotional exhaustion. Namely, Slovenian parents reported roughly 2 h less of paid and 4 h more of unpaid work per day during the lockdown in comparison to nonparents. The analysis also demonstrates that females performed more unpaid work and enjoyed less leisure before the lockdown, but the lockdown adjustment did not further increase gender inequality.

We examine the impact of the rapidly expanding mobile banking service “mobile money” on rural households’ decision to adopt modern agricultural inputs and its resultant effect on agricultural income using plot, household, and community-level panel data from rural Uganda. The main findings indicate that mobile money adoption increases per capita farm income by 13%. Pathway analyses show that mobile money adoption increases the likelihood of using chemical fertilizer on maize plots by 11 percentage points. Mobile money adoption increases the likelihood of high-yielding maize seeds adoption on maize plots by 8.2 percentage points. In the Ugandan context of rapid decline in soil fertility and very low adoption of fertilizer and modern seeds, mobile money provides an avenue to finance agricultural intensification.

This paper analyzes the effect of the COVID-19 pandemic on the within-household gender gap in relation to paid work hours in full-time employed heterosexual couples in Spain. Using the Spanish Labor Force Survey (2019–2020) and a difference-in-differences method, we analyze three stages of the pandemic: strict lockdown, de-escalation, and partial closures to study the short-term effects and potential medium-term effects on gender inequality in terms of paid work hours. Our results suggest that during the strict lockdown period there was a tendency to fall back on traditional family gendered patterns to manage the work–life balance, especially when young children are present in male-headed households. However, this phenomenon seems to be a short-term consequence of the pandemic. The sector of activity (essential or non-essential) has also played a key role, the gender gap increased in male-headed households with female partners employed in non-essential sectors.

Food security in many developing countries has been threatened by several factors such as unequal land distribution, ineffective land reform policies, inefficient agricultural value chains, and an increasing number of climate disasters. In Nigeria, these threats are exacerbated by rapid population growth and extreme weather events, which have resulted in farmer-herder conflicts in most agrarian communities. This paper examines the differential impacts of the incidence and severity of farmer-herder resource use conflicts on food insecurity of rural households in Nigeria. We employ a two-stage predictor substitution model to estimate survey data collected from 401 rural households in Nigeria. The empirical results show that both the incidence and the severity of farmer-herder conflicts significantly increase food insecurity, and the severity of these conflicts has a larger impact than their incidence. The estimates of the conditional mixed process models confirm the robustness of our results. Additional analysis reveals that the incidence and severity of farmer-herder conflicts positively and significantly affect food insecurity, measured by the number of days with limited varieties of food eaten. Our findings highlight the importance of policy interventions that address ongoing farmer-herder conflicts in affected countries like Nigeria to enhance food security from a sustainable development perspective.

We study a parent's demand for gratitude from his child. We view this demand as an intervening variable between the parent's earnings and the incidence of child labor. The demand for gratitude arises from the desire of a parent to receive care and support from his child late in life, while the inclination of the child to provide this support during his adulthood is determined by how the child was treated by his parent during childhood. Specifically, we model the child's gratitude as an inverse function of the intensity of his labor in childhood. We show that when we keep the child's (imputed) wage constant, the intensity of child labor decreases with the parent's earnings. However, when we make the child's (imputed) wage a function of the parent's earnings, then the outcome can be different. With the help of a numerical example, we show that the pattern of child labor related to the parent's earnings can be U-shaped.

Tolerance of sexual minorities is presumed to matter, but its effects are under-studied. Because tolerance can affect both experiences at work and division of labor in the household, we study the relationship between tolerance and the time cohabiting gay men and lesbian women spend in paid work across the United States. In the average state, the increase in tolerance between 2003 and 2015 is associated with an increase in paid work of about 1 week per year among cohabiting gay men. Though not robustly statistically significant, the increase in tolerance is associated with a decrease in paid work among cohabiting lesbian women relative to heterosexual women.

Developing countries experience both household air pollution resulting from the use of biomass fuels for cooking and industrial air pollution. We conceptualise and estimate simultaneous exposure to both outdoor and household air pollution by adapting the Total Exposure Assessment model from environmental health sciences. To study the relationship between total exposure and health, we collected comprehensive data from a region (Goa) in India that had extensive mining activity. Our data allowed us to apportion individuals’ exposure to pollution in micro-environments: indoor, outdoor, kitchen, and at work. We find that higher cumulative exposure to air pollution is positively associated with both self-reported and clinically- diagnosed respiratory health issues. Households in regions with higher economic (mining) activity had higher incomes and had switched to cleaner cooking fuels. In other words, household air pollution due to higher biomass use had been substituted away for outdoor air pollution in regions with economic activity.

Share contracts are the dominant remuneration system in artisanal fisheries. Introducing regulations based on collective use rights may affect the way profits are distributed. The literature on the effect of regulatory reform on factor income distribution, however, is scarce. In this paper, we look at differences in the implementation of the Extractive Artisanal Regime in Chilean hake artisanal fisheries to test its effect on share contracts. We estimated a switching regression model using census data to calculate the average treatment effect. Our results show that crewmembers in communities regulated by some form of collective use rights receive, on average, 6 per cent more of total net incomes compared to those regulated by a limited access with global quota regime. Differences in the relation between crew size and labor rewards, as well as in the negotiating power of crewmembers under different regimes, may explain the results.

Capital and credit constraints limit the small farm’s ability to adequately use resources for optimum performance. Farmers’ access to capital is constrained in multiple ways, including price factors, risk factors, and transaction factors, as well as access to and ease of rural agricultural financing. Using a primary survey data of small farms in Tennessee, we analyzed factors influencing credit constraint and its impact on farm performance. Farm operators’ gender, off-farm work, land acreage holdings, farm specialization, and the use of smart phone with Internet significantly influenced credit constraint. We found that the financial performance of credit constrained small farmers was significantly lower than that of unconstrained small farmers—an adverse impact of constrained capacity to credit could result in up to $51,000 lower in gross farm sales. Additionally, our reason-specific results within credit constraint suggested that around $32,000 to $39,000 lower performance in gross sales can be attributable to the constrained borrowing with deficit to obtain agricultural loans at required or desired level.

The aim of this paper is to investigate the role that the marital status of children has in shaping the living arrangements of their widowed mothers and themselves and to explain the increase in the proportion of elderly widows living alone, which grew by 23.2% in the USA between 1970 and 1990. We propose a model where living arrangements are determined as the outcome of a game between the mother and her child, and where the fundamentals of the model depend on children's marital status. We estimate the model using 1970 data. We calculate the accuracy of the estimation and we obtain an excellent fit. Using the same measure of accuracy, the estimated model predicts that changes in the incomes of both the widow and her offspring and changes in the children's marital status generate more than the 83% of the increase in the number of widows living alone.

The United States saw a rapid transformation of its labor market when the female employment to population ratio nearly doubled from 1950 to 2000. As women shift their hours from the home sector to the market sector, goods that were previously produced in the home may be replaced by market services. This paper uses the Panel Study for Income Dynamics, Consumer Expenditure Survey, and the American Time Use Survey to analyze the extent to which households replace home production with purchased market services, and how the relationship between men’s and women’s labor supplies affects these decisions. We show that women who are employed spend less time on home production activities that have close market alternatives than women who are not employed. Additionally, expenditures on market services that can replace home production are higher for married households in which the woman is employed compared to those with nonworking women.

Researchers have employed farm household models (FHMs) for policy analysis under the separability assumption. However, separability can fail, and the household's production and consumption decisions become simultaneous. Using 5 years of household data, the separability assumption among Ghana's cocoa-producing households is tested via heterogeneity of household adult males and females, household children, and hired and exchange labor. Results show labor is heterogeneous, implying a lack of separability. Simulation analysis also shows that ignoring nonseparability leads to an underestimation of policy effects. Thus, nonseparability in production and consumption decisions must be incorporated in FHMs developed for Ghanaian cocoa-producing households.

This paper studies the distribution of resources within families with migrant member abroad. We derive a complete collective demand system with individual Engel effects for male and female adults and children, and the respective share of resources. The focus is on migrant-sending families in Albania, where gender and inter-generational inequalities are relevant social issues. The results show that the female share of resources is substantially lower with respect to an equal distribution and do not benefit from father’s migration. Children have a larger share of resources and benefit from their fathers migration, when women maintain control over family decisions and when the proportion of female children is larger (at the detriment of women).

This paper applies a discrete choice version of the household production framework to assess parents’ ex ante willingness to pay to reduce their child’s victimization from bullying at school. Willingness to pay is estimated using a bivariate probit model and a unique panel of 595 families from the NICHD Study of Early Child Care and Youth Development for 2000 to 2003. Empirical results find a statistically significant positive association between an elementary school child’s bully victimization and parents’ choice to change their child’s school in the subsequent sample period. Parents’ annual willingness to pay for reduced child bully victimization averages $130 and ranges from $54 for parents whose child was not bullied to $633 for parents whose child was bullied. Given current literature estimates of U.S. bullying prevalence and the cost and effectiveness of currently available anti-bullying programs, parental willingness to pay estimates suggest that U.S. households’ net annual return on investments in elementary school bullying prevention programs could be substantial.

Rice, may be of a high- or low-quality type, based on the size and shape of the rice grain and variety. Thus, perhaps with an increase in income, consumers might not only switch from rice to other high-value-added foods, but also shift away from short-and-bold-grain to long-and-slender-grain rice. Using the case of Bangladesh, this article examines the drivers of change in rice grain-type preferences by households. We econometrically demonstrate that educated, rich, and urban households in Bangladesh are increasingly consuming fine-grain (i.e., long-and-slender-grain) rice, by replacing ordinary-grain (i.e., short-and-bold-grain) rice.

A variety of states in the United States have adopted the “homemaking provision” in their divorce laws since the 1980s. The provision requires judges to recognize homemakers’ contribution to their marriages in dividing marital properties at divorce. I model the marital decisions of couples as a sequential game, in which the potential wife’s decision in whether to marry and specialize in home production depends on whether she is legally protected by the homemaking provision, as the law would reinforce her post-divorce property rights and therefore increase her bargaining power within the marriage. I use the variation in the timing of the passage of the homemaking provision to identify its effect on marriage. I find that the provision substantially increases marriages using both state- and individual-level data.

In order to credibly “sell” legitimate children to their spouse, women must forego more attractive mating opportunities. This paper derives the implications of this observation for the pattern of matching in marriage markets, the dynamics of human capital accumulation, and the evolution of the gene pool. A key consequence of the trade-off faced by women is that marriage markets will naturally tend to be hypergamous – that is, a marriage is more likely to be beneficial to both parties relative to remaining single, the greater the man’s human capital, and the lower the woman’s human capital. As a consequence, it is shown that the equilibrium can only be of two types. In the “Victorian” type, all agents marry somebody of the same rank in the distribution of income. In the “Sex and the City” (SATC) type, women marry men who are better ranked than themselves. There is a mass of unmarried men at the bottom of the distribution of human capital, and a mass of single women at the top of that distribution. It is shown that the economy switches from a Victorian to an SATC equilibrium as inequality goes up.

The model sheds light on how marriage affects the returns to human capital for men and women. Absent marriage, these returns are larger for women than for men but the opposite may occur if marriage prevails. Finally, it is shown that the institution of marriage may or may not favour human capital accumulation depending on how genes affect one’s productivity at accumulating human capital.
