Food Insecurity and Hunger in the Kindergarten Classroom: Its Effect on Learning and Growth

This study investigates the correlation between food insecurity, educational achievement, and health among kindergarten children in the United States. Data from the Early Childhood Longitudinal Study—Kindergarten Cohort are used to analyze educational achievement and physical growth of kindergartners faced with food insecurity. The results demonstrate that children begin to experience the effects of food insecurity even at the most marginal level of household food deprivation. Children in households with any signs of food insecurity score lower and learn less during the school year.     

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.     

The impacts of energy insecurity on household welfare in Cambodia: Empirical evidence and policy implications

This study investigates the impacts of energy insecurity on household welfare in Cambodia. The notion of energy insecurity is not well understood in the literature as well as in local contexts. This study defines household energy insecurity as the status quo derived from the interplay of inadequate and insufficient energy consumption that prevents households from meeting basic energy needs. The notion of energy insecurity can only be well understood by investigation in the local context as it varies from place to place. Households facing insufficient energy consumption may forgo many other opportunities. Once energy security has been defined in the Cambodian context, the study employs multiple regression models using the Cambodia Socio-Economic Survey Data (2015) to investigate the impacts of household energy insecurity. The study confirmed that energy insecurity has enormous negative impact on welfare of the households, with a further negative impact on the human capital formation of the children. The findings will lead to policy implications to improve household energy security, and thus impact economic, social, and environmental development.     

Gender and household education expenditure in Pakistan

Pakistan has very large gender gaps in educational outcomes. One explanation could be that girls receive lower educational expenditure allocations than boys within the household, but this has never convincingly been tested. This article investigates whether the intra-household allocation of educational expenditure in Pakistan favours males over females. It also explores two different explanations for the failure of the extant ‘Engel curve’ studies to detect gender-differentiated treatment in education even where gender bias is strongly expected. Using individual level data from the latest household survey from Pakistan, we posit two potential channels of gender bias: bias in the decision whether to enrol/keep sons and daughters in school, and bias in the decision of education expenditure conditional on enrolling both sons and daughters in school. In middle and secondary school ages, evidence points to significant pro-male biases in both the enrolment decision as well as the decision of how much to spend conditional on enrolment. However, in the primary school age-group, only the former channel of bias applies. Results suggest that the observed strong gender difference in education expenditure is a within rather than an across household phenomenon.     

The Effects of Disability on Labour Force Status in Australia

Using the Australian Bureau of Statistics 1998 Survey of Disability, Ageing and Carers, this study examines the effects of disability on four labour market outcomes: not in the labour force, unemployed, part‐time employed and full‐time employed. The detailed information on health available in the dataset also facilitates investigation of the dependence of effects on the characteristics of the disability, including severity, impairment type and age of onset. Disability is found to have substantial effects on labour force status, on average acting to decrease the probability of labour force participation by one‐quarter for males and one‐fifth for females. For males, the decrease in fulltime employment accounts for almost all of the decrease in labour force participation associated with disability; for females, disability has negative effects on both full‐time and part‐time employment. Analysis of disability characteristics shows that adverse effects on labour force status are increasing in the severity of the disability and are also worse for those with more than one type of impairment and for those who experience disability onset at older ages. There is evidence that the adverse effects of disability are lower for males who completed their education after the onset of the disability.     

The determinants of access to health care and medicines in India

This article explores the issue of demand for health care and medicines in India where household share of total health expenditure is one of the highest among high- and low-income countries. Previous work found that important determinants include health status, socio-demographics, income and demand for care was inelastic. Compared with previous studies, this article uses large household data sets including data on medicine expenditure to explore health-seeking behaviour. Count models find that determinants include health status, socio-demographic information, health insurance, household expenditure and government regulation. Elasticities range from ?0.13 to 0.03 and are generally consistent with literature findings. For inpatient care, conditional on having at least one hospitalization, the expected number of hospitalizations increases with being male and household expenditure. Medicine expenditure accounts for a large share of household health expenditure. Low-income individuals could experience problems and raises important policy implications on the demand and supply side to improve access to health care and medicines for patients in India.     

The self-reinforcing dynamics of economic insecurity and obesity

This article models the dynamic effects of economic insecurity on body weight. Using Australian panel data, we infer an individual’s level of economic insecurity as a function of exposure to various financial risks and employ regression equations to explore its effect upon current period body mass index (BMI) scores. Estimates reveal that a sustained standard deviation increase in economic insecurity raises an individual’s BMI at a rate of approximately 0.35 units per year. Quantile regressions are then used to estimate the sensitivity of body weight to insecurity at different percentiles of the distribution and we find that persons who are overweight and obese are much more seriously affected. This implies that shocks that make individuals more financially vulnerable can generate harmful self-sustaining cycles of risk and weight gain. We also model the dynamics of insecurity and show that it is a persistent phenomenon for persons with high levels of exposure and lower incomes. This finding indicates that persons of lower socio-economic status are more likely to encounter vicious cycles of increasing insecurity and obesity, which partially explains why weight-related health problems are unusually highly concentrated amongst these individuals.     

Job insecurity and mental health in Canada

Using six cycles of Canada’s longitudinal National Population Health Survey data (2000–2001 to 2010–2011), this article examines the relationship between job insecurity and mental health. Job insecurity is evaluated in both subjective (perception of job insecurity) and objective (probability of joblessness) terms while mental health is measured using a standardized psychological distress index. Applying a person-specific fixed-effects estimator, results indicate that for males and females age 25–64, job insecurity, regardless of how it is measured, is associated with an increase in psychological distress. Results regarding unemployment are not as conclusive, suggesting that it is not so much the actual occurrence of job loss but the threat of unemployment that is associated with higher psychological distress. Estimates of the relationship between job insecurity and psychological distress using pooled ordinary least squares are much larger, implying that much of the psychological distress/job insecurity correlation may be due to unobservable fixed characteristics. All results are robust to the inclusion and exclusion of a host of other potential determinants including income-related variables, education, and various health measures.     

Valuing the Incremental Benefits of Groundwater Protection when Exposure Levels are Known

Both economic theory and psychological research indicate that benefit functions for reductions in health risk exposures may be conditional on current exposures. Using nitrates found in household wells, it is demonstrated that perceptions of health risks across exposure levels are affected by the individual's current exposure level, thus providing support for a conditional benefits function approach. Functions of conditional incremental benefits are estimated from a contingent valuation study of households that had been informed of their water test results. Incremental benefits reach a peak at an intermediate level of nitrates and then decline. Possible explanations for this non-convexity are provided.     

Political instability and households’ investment behavior: Evidence from Burkina Faso

There is a large, rather macroeconomic, literature that shows that political instability and social conflict are associated with poor economic outcomes including lower investment and reduced economic growth. However, there is only very little research on the impact of instability on households’ behavior, in particular their saving and investment decisions. We merge six rounds of household survey data and a geo-referenced time series of politically motivated events and fatalities from the Armed Conflict Location and Event Data Base (ACLED) to analyze households’ decisions when exposed to instability in Burkina Faso. For identification, we exploit variation in the intensity of political instability across time and space while controlling for time- and municipality-fixed effects as well as rainfall and nighttime light intensity, and many other potential confounders. Our results show a negative association of political instability and financial savings, the accumulation of durables, investment in house improvements, as well as investment in education and health. Instability seems, in particular, to lead to a reshuffling from investment expenditures to increased food consumption, implying lower growth prospects in the future. With respect to economic growth, the sizable education and health effects seem to be particularly worrisome.     

Household food demand in rural China

This article explores rural household food consumption behaviour in China using a large household data set from Jilin Province. Data are classified into four main food groups—grain, vegetable products, animal products and other foods. A household food demand system, incorporating four household characteristics, is estimated using an LA-AIDS model, assuming a three-stage budgeting procedure. Expenditure elasticities for a range of food groups are estimated, with a particular focus on animal products. The inclusion of household characteristics did not have a big impact on the elasticity values in any of the three stages of the budgeting process. The total expenditure elasticity for grain (Stage II) was 0.64, suggesting substantial future growth in household demand for fine grains such as rice and wheat, as per capita incomes continue to grow in rural areas. The highest conditional and total expenditure elasticity values were for the animal products (Stage II) group, 1.22 and 0.76, respectively. Within this group the elasticities were highest for the meat sub-group at 1.14 and 0.87, respectively, suggesting an almost proportionate increase in demand as household incomes grow. Added demand pressures from animal production will likely keep grain policy high on the political agenda.     

Measuring wage discrimination in Italy: a random-coefficient approach

Using data from a representative 1989 household survey for Italy we estimate random-coefficient earnings frontiers by gender, marital status and location. These estimates are used to calculate discrimination indices. Our results show that fixed coefficients can be rejected in all cases. A wide range on the estimated coefficients indicates a high degree of variation in the quality of the observed human-capital variables as well as different degrees of ability as perceived by the employer. We find reverse discrimination for single females in the South and the North. For married females there is evidence of discrimination, particularly in the South. We isolate the effects of tenure and education on discrimination and find that these reduce discrimination for Southern-married females.     

The relationship between childhood obesity and food insecurity: a nonparametric analysis

Childhood obesity and food insecurity are major public health concerns in the United States and other developed countries. Research on the relationship between the two has provided mixed results across a variety of data sets and empirical methods. Common throughout this research, however, is the use of parametric frameworks for empirical analyses. This study moves beyond parametric methods by examining the relationship between childhood obesity and food insecurity among low-income children with nonparametric regression techniques. We examine data from the Child Development Supplement (CDS) of the Panel Study of Income Dynamics (PSID), a nationally representative data set from the US. Consistent with recent work, our parametric analyses indicate that there is no statistically significant relationship between childhood obesity and food insecurity. In contrast, our nonparametric results indicate that the probability of being obese varies markedly with the level of food insecurity being experienced by the child. Moreover, this relationship differs across relevant subgroups including those defined by gender, race/ethnicity and income. Fully understanding the relationship between childhood obesity and food insecurity has significant policy implications.

Income and Health Concentration in Australia

This paper measures the concentration of ill-health among income groups in Australia using health survey data from 1989–90 ( Australian Bureau of Statistics 1991 ) and 1995 ( Australian Bureau of Statistics 1997 ), which contain responses on self-assessed health status and gross personal income. The technique of direct standardisation is used to control for the influence on health status of gender and age. Comparisons of the concentration of ill-health over time and between males and females and persons living in rural and urban areas are reported. For both surveys and all groups, we find that ill-health is concentrated among lower income groups. Concentration measures of ill-health are higher (in absolute terms) for men than for women. In all categories apart from women, the concentration measures fell between 1989–90 and 1995 surveys.     

Endogenous Debt Constraints in Lifecycle Economies

We characterize competitive equilibria with perfect foresight in a deterministic, three-period pure-exchange overlapping generations economy with perfect information and no commitment to loan contracts. Commitment is replaced by an enforcement mechanism that excludes defaulters from asset markets for one period. For hump-shaped endowment profiles, young individuals face endogenous debt constraints that ration current consumption. Changes in current and future yields affect these constraints, inducing an additional income effect on rationed household demand that makes current and future consumption complements. This mechanism can lead to multiple steady states, persistent indeterminacy and regime switching. We show that sensitivity to shocks and complex dynamic behaviour are consistent with endogenous debt limits but not with exogenous liquidity constraints.     

Does more cash in conditional cash transfer programs always lead to larger impacts on school attendance?

There is considerable evidence that conditional cash transfer (CCT) programs can have large impacts on school enrollment, including in very poor countries. However, little is known about what features of program design account for the observed outcomes. In this paper we analyze the impact of a program in Cambodia that made payments of varying magnitude to otherwise comparable households. The identification is based on a sharp regression discontinuity design. We find that a modest cash transfer, equivalent to approximately 2% of the consumption of the median recipient household, had a substantial impact on school attendance, approximately 25 percentage points. A somewhat larger transfer did not raise attendance rates above this level.     

Indirect Tax Reform in Australia: The Welfare Effects on Different Demographic Groups

The welfare effects of several indirect tax reforms in Australia are examined for a number of types of household in a range of income groups. The welfare changes, measured using equivalent variations, are based on the use of the linear expenditure system, where parameters are different in each of the income groups. The effects of the current system and of several reforms are found to differ significantly among the household types. However, the results suggest that the extent of vertical redistribution involved in the current indirect tax structure, and possible reforms to it, are small. The role of exemptions are examined in the case of food, for which the budget shares are systematically higher in lower income households, and health services. In view of the strong assumptions used at each stage, the results must be regarded as tentative.     

Do School Subsidies Promote Human Capital Investment among the Poor?*

We investigate the hypothesis that conditioning transfers to poor families on school attendance leads to a reallocation of household resources which enhances the human capital of the next generation, via the effect of the conditionality on the shadow price of human capital and (possibly) via the effect of the transfers on household bargaining. We introduce a model to study the effects of conditional transfers on intra‐household allocations, and provide suggestive evidence of the importance of price effects using data from a conditional transfer program in Mexico.     

THE IMPACT OF INTRA HOUSEHOLD BALANCE OF POWER ON EXPENDITURE PATTERN: THE AUSTRALIAN EVIDENCE*

The collective approach to household behaviour models the household utility function as the weighted average of the utilities of the individual members of the household. These weights, which measure the relative bargaining power of males and females within the household, are generally regarded as fixed and exogenous. The paper extends the collective approach and estimates a model where the weights are endogenously determined. The novelty of the analysis lies in the simultaneous equations estimation of the bargaining power and the budget share equation that allow for the endogeneity of the power variable in the examination of its impact on the budget share of the various items. The estimation is conducted using data from the 1998–99 Australian Household Expenditure Survey data set. The relative bargaining power of males and females have statistically significant effects on household expenditure patterns. The analysis reveals some interesting non‐monotonic relationships between relative power and budget shares that vary a great deal between commodities.
