Household Food Insecurity and Maternal and Child Nutritional Status: Evidence from Maharashtra

In this paper we rigorously examine the association of household food security status with maternal and child nutritional status exploring a rich micro‐level database, the Comprehensive Nutrition Survey Maharashtra 2012. Using Household Food Insecurity Access Scale (HFIAS) as a metric to measure household food security, we apply simultaneous probit models to estimate the effect of food insecurity on maternal and child nutritional outcomes. The modelling framework addresses possible endogeneity in the above relationship. Findings indicate that household food insecurity increases the risk of maternal and child underweight with no effect on child stunting, wasting or maternal overweight. Women’s decision‐making power mediates these associations. Food security interventions should be effective in tackling the concerns with undernutrition, however, food alone is not the solution. A mix of nutrition‐specific and nutrition‐sensitive policies is warranted. Food security interventions should be integrated into policies for human development.     

Determinants of child mortality,health, and nutrition in a developing country

The authors investigate the determinants of child mortality and health and nutrition status in Nicaragua using economic models of household behavior. In particular, they examine regional differences by degree of urbanization. Various factors affecting child mortality are considered. The results indicate that "income is not an important factor, there is an inverse relation with number of siblings, and there are positive associations with calorie intake, schooling (except in the relatively low-income areas), the availability of refrigeration, and the quality of sewage systems."     

Part‐Peasants: Incomplete Rural–Urban Labour Migration in China

The institutional settings in China, including the land allocation system and the household registration system, lead to a rural–urban labour migration pattern that differs from that in other countries. Individual peasants' labour is often split (typically over different times of the year) into two or more parts as a result of institutional factors. Individuals work both as peasants on the land and as temporary migrant workers in urban areas (or in rural non‐agricultural sectors). We examine this issue using province‐level panel data. The present study provides a new interpretation of the phenomenon of labour shortages in coastal cities and rising rural migrant wages in China in recent years, and discusses whether the Lewisian turning point has been reached. Under part migration, the rural labour supply to urban areas is smaller than would be the case with full migration of workers to urban areas, so that the Lewisian turning point occurs earlier. This finding has important policy implications for China's future development.     

Impact of remittances on male and female labor force participation patterns in Africa: Quasi‐experimental evidence from Ghana

In this paper, we examine how remittances, an outcome of labor mobility, affect labor market activities in Ghana using detailed household and individual‐level data. This is important, considering the extensive literature that has documented the remittance–poverty reduction nexus. First, we find a strong negative association between household remittance‐receiving status and individual labor supply decisions using instrumental variable estimation techniques. Second, we find the depressing effect of remittances on labor supply decisions to be much stronger in rural areas. Rural women who reside in remittance‐receiving households are less likely to be in the labor force compared with those who do not reside in such households. Remittances have very little impact on labor supply decisions in urban areas. Our findings support that remittances can exacerbate long‐term poverty reduction in rural areas through lower labor force participation, and as such rural‐based and gender‐based interventions may be needed to help redirect remittance income.     

Microcredit,Labor, and Poverty Impacts in Urban Mexico

Improved household accessibility to credit is a significant determinant of intra‐household allocation of labor resources with important implications for productivity, income, and poverty status. However, credit accessibility could also have wider impacts on poverty if it leads to new hires outside the household. This paper contributes to the existing literature on microcredit in two important ways. First, it investigates the routes through which microcredit reaches those in poverty outside the household. We test whether by lending to the vulnerable non‐poor microcredit can indirectly benefit poor laborers through increased employment. Second, we conduct the study in the context of urban poverty Mexico. This is relevant when considering that labor often represents the only source of livelihoods to the extreme urban poor. Our findings point to significant trickle‐down effects of microcredit that benefit poor laborers; however, these effects are only observed after loan‐supported enterprising households achieve earnings well above the poverty line.     

Son Preference and Gender Gaps in Child Nutrition: Does the Level of Female Autonomy Matter?

This paper examines the association between parental son preference and child anthropometric status, and the extent to which this relationship depends on the level of female autonomy. Results highlight the importance of maternal son preference and mothers' involvement in household decision making when gender gaps in child nutrition are considered. These findings have important policy implications.     

Child labor and the minimum wage: Evidence from India

This study examines how changes in the minimum wage affect child labor in India. The analysis uses repeated cross sections of India's NSSO employment data from 1983 to 2008 merged with data on state-level minimum wage rates. Theoretically, the impact of the minimum wage on child work could go either way, so empirical evidence from a country with high rates of child labor and a myriad of minimum wage laws across states and industries helps to lessen the ambiguity. Results indicate that regardless of gender, in urban areas, a higher minimum wage reduces child labor in household work. In rural areas a similar result applies for girls while household labor does rise for boys. The minimum wage has virtually no impact on child work outside of the home across urban and rural areas.     

POOR AND SICK: ESTIMATING THE RELATIONSHIP BETWEEN HOUSEHOLD INCOME AND HEALTH

This study evaluates the effect of the individual's household income on their health at the later stages of working life. A structural equation model is utilized in order to derive a composite and continuous index of the latent health status from qualitative health status indicators. The endogenous relationship between health status and household income status is taken into account by using IV estimators. The findings reveal a significant effect of individual household income on health before and after endogeneity is taken into account as well as a host of other factors known to influence health, including hereditary factors and the individual's locus of control. Importantly, it is also shown that the childhood socioeconomic position of the individual has long lasting effects on health as it appears to play a significant role in determining health during the later stages of working life.     

Child endowments and parental investments: Intra‐household allocation in oportunidades families in Mexico

This paper estimates a family fixed‐effects model to test whether parental educational investments are reinforcing or compensating differences in child height and body mass index (BMI) within Oportunidades households. The results indicate that allocations are not made in response to endowment differences in isolation, but depend on the interaction of child endowment, gender, and beneficiary status. Moreover, investments are made so as to counterbalance efficiency and equity considerations: widening differences in height but closing gaps in BMI, where both strategies maximize returns given the earnings–endowment function for height and BMI in Mexico. Finally, household socio‐economic status matters. Thus, discriminatory responses within the better‐off urban beneficiary households are smaller. In contrast, indigenous beneficiary households, which have the lowest average endowment z‐scores and fraction spent on education, see the largest differences in educational outlay between child subgroups. While the economic effects seem small, these are measured relative to the mean of the base category. In some cases, then, parents are dedicating nearly a quarter of all expenditures to education for a standard deviation increase in endowment over mean sibling endowment. Hence, it seems that the success of the Oportunidades program in improving overall human capital formation may be masking rising inequalities within recipient households.     

Family policy,intrahousehold bargaining,and child health

This study examines the effects of an exogenous change in family policy in Ethiopia on women empowerment and the allocation of resources toward child health. Empowerment is formalized as an unobserved latent variable based on a large set of questions pertaining to women's autonomy and decision-making power. Exploiting the time and regional variation in the implementation of the law, the study finds that early implementation of the reform increases women's access to information, literacy and education levels, and their assertiveness toward family planning and domestic violence. In addition, more decision power in the hands of women is found to have a positive impact on investments in the health and nutrition of children. The findings suggest that factors that do not enter the individual's preferences may affect outcomes for individuals and emphasize the role of intrahousehold heterogeneity. The results are robust to a battery of validity and specification checks.     

Parental compensatory behaviors and early child health outcomes in Cebu,Philippines

A dynamic optimization model of parents choosing investments in their children's health motivates an empirical model of parents' choices of health inputs for their children and the impacts of these decisions on their children's subsequent health. Estimates of the child health input demand functions and the child health production functions from the Cebu Longitudinal Health and Nutrition Survey accord with the prediction that optimizing behavior results in higher levels of aggregate child health. Observable parental behaviors respond to the physical developmental status of their children. These parental responses appear to yield large and statistically significant improvements in children's early physiological outcomes. However, because some health inputs choices are not observable, it is impossible to ascertain whether these measured effects are due solely to variations in the observed input choices.     

Is perceived financial inadequacy persistent?

In an attempt to understand the determinants of financial inadequacy, this paper employs the ability of households to make ends meet as a measure of their perceived financial inadequacy. Using household‐level data from the European Community Household Panel covering eight countries over the period from 1994 to 2001, this study applies a dynamic probit model that incorporates both state dependency and individual fixed effects. Exploiting a latterly enhanced bias‐corrected fixed‐effects probit model, I address the persistent nature of subjective financial inadequacy by directly estimating fixed effects while correcting for incidental parameters and avoiding the initial conditions problem of dynamic models. The results reveal that employing time‐invariant individual effects to model subjective monetary perception is essential. However, by controlling for household heterogeneity, income, indebtedness, and health status, I find that in addition to the major differences across European households, country‐specific factors can have adverse effects on the persistent nature of perceived financial inadequacy.     

The Effect of Parental Absence on Child Development in Rural China

This study estimates the effect of parental absence on the development of children in rural China. Although some previous studies have looked into the effect of parental absence on children's academic achievements, we investigate the effects of parental absence on both the cognitive and non‐cognitive skills of children. Our results show that parental absence during early child development mostly incurs negative effects on the academic achievement and non‐cognitive development of children. A child whose parents are both absent tends to have lower Chinese and mathematics test scores, lower self‐assessment on his/her behavior, and is less likely to be happy and satisfied. A gender difference is also observed in the effect of parental absence: girls suffer more from the effect of both parents being absent on their mathematics test scores than do boys.     

FAMILY PLANNING AND WOMEN'S EDUCATIONAL ATTAINMENT: EVIDENCE FROM THE ONE‐CHILD POLICY

This paper exploits China's one‐child policy (OCP) to study the relationship between fertility and educational attainment of the mothers of China's “sibling‐less generation.” I take two difference‐in‐differences approaches to estimate the OCP's effect on women's education: one compares gender difference among the ethnic majority group and the other compares ethnicity differences between ethnic majority women and ethnic minority women. I also explore the heterogeneity of the policy's effects by parent's status at the Communist Party. I find that the OCP has a positive and significant effect on women's education and explains about half of the increase in educational attainment for women born between 1960 and 1980. Their increased educational attainment associates with delayed entry into first marriage, delayed entry to parenthood and increased labor supply. (JEL I20, J13, J16, J18)

A test of a unitary model on labour supply using the information of household decision-making systems

This article tests whether a unitary model is consistent with household behaviour using the data of two-earner couples. It focuses on the unitary model assuming that all family members have the same utility function. The analysis investigates the difference in a husband's and wife's labour supply between the household that determines the wife to be the main decision-maker and the household that selects a different decision-making system under the control of individual and household characteristics. The estimation employs a treatment effects model to consider the selectivity bias caused by unmeasured characteristics. Results show that the household with the wife as the main decision-maker increases the husband's working hours by 15% and decreases the wife's working hours by 59%, compared to the household that selects a different decision-making system. This implies that the unitary model is rejected. Additionally, the husband's wage rate, the husband's and wife's health status, and their gambling addiction determine the household decision-making system such as the variables that determine the reservation utility of not being married. The effect of the decision-making system on the labour supply and that of the determinant factors on the decision-making system are consistent with the implications obtained from Nash bargaining models and collective models.     

Aging,Savings, and Public Pensions in Japan*

We analyze the impact of population aging on Japan's household savings rate and on its public pension system and the impact of that system on Japan's household savings rate and obtain the following results: first, the age structure of Japan's population can explain the level of, and past and future trends in, its household savings rate; second, the rapid aging of Japan's population is causing Japan's household savings rate to decline and this decline can be expected to continue; third, the pay‐as‐you‐go nature of the public pension system, combined with rapid population aging, created considerable intergenerational inequities and increased the savings rates of cohorts born after 1965, which in turn slowed the decline in Japan's household savings rate; and fourth, the 2004 public pension reform alleviated the intergenerational inequities of Japan's public pension system somewhat but will in the long run exacerbate the downward trend in Japan's household savings rate.     

A STOCHASTIC DYNAMIC MODEL OF THE MENTAL HEALTH OF CHILDREN*

We estimate the parameters of a dynamic multiperiod model where parents with one child periodically decide whether their child uses mental health services. In this model, parents receive utility from household consumption and from their child's mental health. Mental health services may improve the child's mental health, but may be costly in terms of reduced household consumption and direct disutility. We find that mental health services can slightly improve a child's mental health, but the use of services accounts for a small fraction of the improvement of the mental health of the children in our sample.     

SOCIAL COMPARISON AND SUBJECTIVE WELL‐BEING: DOES THE HEALTH OF OTHERS MATTER?

The importance of social comparison in shaping individual utility has been widely documented by subjective well‐being literature. So far, income and unemployment have been the main dimensions considered in social comparison. This paper aims to investigate whether subjective well‐being is influenced by inter‐personal comparison with respect to health. Thus, we study the effects of the health of others and relative health hypotheses on two measures of subjective well‐being: happiness and subjective health. Using data from the Italian Health Conditions survey, we show that a high incidence of chronic conditions and disability among reference groups negatively affects both happiness and subjective health. Such effects are stronger among people in the same condition. These results, robust to different econometric specifications and estimation techniques, suggest the presence of some sympathy in individual preferences with respect to health and reveal that other people's health status serves as a benchmark to assess one's own health condition.     

Born like China,growing like China

This paper studies the effects of China's one‐child policy on saving and foreign reserve accumulation. Fertility control increases the saving rate both by altering saving decisions at the household level, and by altering the demographic composition of the population at the aggregate level. I show that demographically induced changes in saving explain the build‐up of a large foreign surplus in China. As in Song, Storesletten, and Zilibtti (2011), the model features contractual and financial market imperfections. Government‐owned firms are less productive but have full access to the credit market. Entrepreneurial firms are more productive but face credit constraints. As labour switches from less productive to more productive firms, demand for domestic bank borrowing decreases. As saving increases while demand for loans decreases, domestic savings are invested abroad, generating a foreign surplus. The model predicts that China's foreign reserve accumulation will soon begin to slow down in response to recent relaxation of the one‐child policy.
