An Investigation of the Household Economy: Coffee Production and Gender Relations in Papua New Guinea

Using two years of intra‐household data from one area of the Papua New Guinea Highlands this article examines the impact of gender relations on household coffee production. Poor relative labour returns for women and the unequal distribution of tasks within the household were found to exert considerable influence on the level of household success in cultivating coffee. The article concludes with the construction of a model linking the intra‐household distribution of economic benefits, determinants of household resource allocation and underdevelopment.     

Education and Household Inequality Change: A Decomposition Analysis for India

Rising returns to education have increased wage inequality in many developing countries, but their impact on inequality between households is less clear. This study asks how education contributed to household inequality in India during the period 1993–2004, using a regression based decomposition method. We find that rising returns to education of employees did not increase household inequality, because many household heads are self-employed. Instead, rising inequality in education contributed to higher inequality, partly because fertility declined more slowly among illiterates. These new insights into the education-inequality relationship in India underline the importance of household-level analysis to complement earnings inequality research.     

Self-employment earnings and returns to education in rural Peru

This article estimates the returns to education for households who derive part of their income from household based non-farm self-employment ventures in rural Peru. While education is an individual level variable, earnings are observed at the household level. This asymmetry complicates both the estimation and the interpretation of the returns to education. This article is the first jointly to incorporate three channels through which education affects household earnings. Education affects earnings through the marginal productivity of labour (worker effect), labour allocation across activities (between-activity allocative effect) and its production externality effect (spillover effect). The results suggest that the between-activity allocative effects of education dominate the returns. This article also makes novel use of economic geography to proxy for the role that access to markets plays in determining these returns. In particular, altitude is a strong predictor of activity choice and the returns to education in this mountainous country.     

The Bang for the Birr: Public Expenditures and Rural Welfare in Ethiopia

This article explores the impact of different types of public spending on rural household welfare in Ethiopia. The analysis reveals that public spending on road infrastructure is characterised by relatively high, but regionally strongly concentrated, returns in terms of rural household welfare. This is quite in contrast to the returns to public expenditures in education, which have attributes of much wider reach but less intensity. Public investments in agriculture show results that are low in magnitude and in statistical significance, mostly due to a poor link between public expenditures in agriculture and productivity in the sector.     

Who Gains More from Education? A Comparative Analysis of Business,Farm and Wage Workers in India

The economics literature on returns to education has focused largely on wage workers, thereby ignoring a sizable section of the workforce which is self-employed. This paper presents the estimates of private returns to education for business, farm and wage workers in India using a nationally representative household survey. The paper addresses the sample-selectivity issue arising due to endogenous sector allocation in the earnings equation using the multinomial-selection approach. Our results show that the average rate of return to education is higher for wage workers followed by business and farm workers. Focusing only on wage workers would provide an overestimate of returns by 30 per cent for business workers and by 40–50 per cent for farm workers. Further, the profile of returns across the education ladder varies perceptibly for the three type of workers with higher education being more rewarding for wage workers.     

Food energy intake and cost of basic needs: Measuring poverty in Bangladesh

Past estimates of poverty in Bangladesh based on the food energy intake method found decreasing poverty over time and similar poverty in urban and rural areas. Using the cost of basic needs method, we find increasing poverty for 1984–92 and higher poverty in rural than urban areas. Examples of lack of consistency in past estimates are highlighted. A method is introduced to assess the gap narrowing and re‐ranking impacts on poverty measures of changes in poverty lines. The article also estimates the marginal impact of household characteristics such as household size, education, occupation and land ownership on the probability of being poor.     

Factor Proportions,Openness and Factor Prices in Kenya 1965–2000

This study analyses how changes in factor abundance and openness have affected relative factor prices in Kenya since 1965, using cointegration analysis and error correction models of relative factor prices. We find that factor proportions determined relative factor prices in the long run, while openness, measured by three different proxies, possibly had a short run effect on relative factor returns. The only deviation from this pattern occurred during the latter half of the 1990s when there was rapid wage growth, mainly due to labour market deregulation.     

The dynamics of welfare gains and losses: An African case study

This article uses panel survey data for Côte d'Ivoire to investigate the determinants of welfare gains and losses of households over time. A first‐difference model is estimated which takes account of initial conditions. For urban areas, it was found that human capital is not only a key explanatory factor for levels of welfare, but also the most important endowment to explain welfare changes over time. In rural areas, physical capital, especially land and farm equipment, mattered most. Household size and composition and socioeconomic characteristics of the household also affected welfare changes. Policy implications are discussed.     

The personal and the factor distributions of income in a cross-section of countries

The shares of capital and labour in national income vary substantially both over time and across countries. This paper shows that the factor distribution of income is an essential determinant of the personal distribution of income. We use cross-country and panel data for a group of developed and developing countries to show that a larger labour share is associated with a lower Gini coefficient of personal incomes. This effect is not only statistically significant but also economically important. An increase in the labour share in Mexico to that observed in the US would reduce the Gini coefficient of the former by between two and five points.     

The Role of Empowerment in Agricultural Production: Evidence from Rural Households in Niger

We use new household and individual level WEAI data from the Tahoua region of Niger and estimate a variable coefficient Cobb-Douglas production function in which traditional inputs interact with two human capital variables – empowerment and formal education. Our estimation results reveal that human capital matters for productivity. So much so that it can be considered as technology-changing, significantly affecting a household’s production technology by enhancing returns to equipment. In fact, differentiating households by their status as dual or primary with only an adult female or male reveals that the productivity elasticity of empowerment is large for dual households in which women are the least empowered. Enhancing the empowerment of women in this group of households, by increasing their leadership skills or tenure security, would yield important productivity gains.     

Household income dynamics: a four-country story

In this article, we analyse the dynamics of household per capita incomes using longitudinal data from Indonesia, South Africa, Spain and Venezuela. We find that in all four countries reported initial income and job changes of the head are consistently the most important variables in accounting for income changes, overall and for initially poor households. We also find that changes in income are more important than changes in household size and that changes in labour earnings are more important than changes in other sources of household income.     

Distributional Effects of Maize Price Increases in Malawi

Abstract

In the wake of highly volatile world prices of staple commodities, we examine the impacts of increases in maize prices on various categories of households in Malawi. Using household-level data, changes in household income are calculated taking into account the net maize production status of the household and food price elasticities estimated from a censored demand system. While maize price increases have unequivocal deleterious effects on the incomes of urban households, rural households experience differential impacts. Net producing households in rural areas benefit from price increases with households above the poverty line obtaining proportionally higher incomes.     

Accounting for Changing Earnings Inequality in Costa Rica, 1980–99

After declining from the mid-1970s to the mid-1980s, inequality in monthly earnings in Costa Rica stabilised from 1987 to 1992 and then increased from 1992 to 1999. In this article, we use recently developed techniques to measure the extent to which these changes in earnings inequality were the result of changes associated with the distributions of personal and workplace characteristics of workers or the earnings differences associated with those characteristics. We present evidence that the most important cause of the fall in inequality prior to 1987 was a decline in returns to education. Inequality stopped falling in Costa Rica in the 1990s in part because returns to education stopped falling. The most important cause of rising inequality in monthly earnings in the 1990s was an increase in the proportion of workers working a non-standard work week (part-time or over-time).     

Agricultural Production,Dietary Diversity and Climate Variability

Abstract

Nonseparable household modelsoutline the interlinkage between agricultural production and household consumption, yet empirical extensions to investigate the effect of production on dietary diversity and diet composition are limited. While a significant literature has investigated the calorie-income elasticity abstracting from production, this paper provides an empirical application of the nonseparable household model linking the effect of exogenous variation in planting season production decisions via climate variability on household dietary diversity. Using degree days, rainfall and agricultural capital stocks as instruments, the effect of production on household dietary diversity at harvest is estimated. The empirical specifications estimate production effects on dietary diversity using both agricultural revenue and crop production diversity. Significant effects of both agricultural revenue and crop production diversity on dietary diversity are estimated. The dietary diversity-production elasticities imply that a 10 per cent increase in agricultural revenue or crop diversity result in a 1.8 per cent or 2.4 per cent increase in dietary diversity respectively. These results illustrate that agricultural income growth or increased crop diversity may not be sufficient to ensure improved dietary diversity. Increases in agricultural revenue do change diet composition. Estimates of the effect of agricultural income on share of calories by food groups indicate relatively large changes in diet composition. On average, a 10 per cent increase in agricultural revenue makes households 7.2 per cent more likely to consume vegetables, 3.5 per cent more likely to consume fish, and increases the share of tubers consumed by 5.2 per cent.     

Gender differences in the incidence of rural to urban migration: Evidence from Kenya

This article examines gender differences in the incidence of rural to urban migration in developing countries, particularly those of Sub‐Saharan Africa. The study distinguishes itself from current migration literature by suggesting that the gain in returns to observable attributes, as a result of migration, may differ by gender and could provide an explanation for gender differences in migration. Using data from Kenya, we estimate the urban‐to‐rural wage gap, separately for each gender, and decompose the gap into the components due to urban to rural differences in observable attributes and differences in returns to observable attributes. We find that the portion of the wage gap that is due to the gain in returns to observable attributes is larger for males, suggesting that males receive larger monetary returns as a result of migration and, consequently, have greater incentive to migrate to urban areas.     

Labour Market Impacts of School Expenditure and Class Size: Evidence from China

This study is a first attempt to estimate the impact of school resources on students’ subsequent labour market earnings in China. Combining unprecedented school data from the early 1950s to the 1990s with household survey data in the 2000s, this paper documents that expenditure-per-pupil, a proxy measure of school resources (or quality) has a significant impact on the level of subsequent earnings through its influence on education returns. The positive effect calls for policy intervention aimed at improving education, to be based on the perceived economic return to the quantity as well as the quality components of education.     

Household Saving Behaviour in an Extended Life Cycle Model: A Comparative Study of China and India

This paper examines the determinants of household saving in China and India over the last few decades using the life cycle model, with appropriate modifications to account for the expected benefits of pension saving. Consistent with the predictions made in the life cycle model, higher income growth promotes more household saving, and higher age dependency does the opposite. An increase in the inflation rate appears to encourage household saving. Interestingly, the evidence suggests that an increase in expected pension benefits tends to discourage household saving in China in the long run, but the reverse is found in India.     

The Impact of Bt Cotton on Poor Households in Rural India

The impact of genetically modified (GM) crops on the poor in developing countries is still the subject of controversy. While previous studies have examined direct productivity effects of Bacillus thuringiensis (Bt) cotton and other GM crops, little is known about wider socioeconomic outcomes. We use a microeconomic modelling approach and comprehensive survey data from India to analyse welfare and distribution effects in a typical village economy. Bt cotton adoption increases returns to labour, especially for hired female workers. Likewise, aggregate household incomes rise, including for poor and vulnerable farmers. Hence, Bt cotton contributes to poverty reduction and rural development.     

An Unconditional Quantile Regression Based Decomposition of Spatial Welfare Inequalities in Ghana

Ghana has witnessed tremendous economic growth since the 1990s and attained the Millennium Development Goals target of halving poverty. This notwithstanding, inequality in Ghana increased over the same period, suggesting growth benefits were not equitably distributed. This study provides evidence on the determinants of household consumption expenditure and factors that explain rural-urban welfare gaps between 1998 and 2013. The study employs an unconditional quantile regression and recently proposed decomposition technique based on re-centred influence functions. We find significant spatial differences in consumption expenditure across selected quantiles, with rural-urban inequalities driven largely by differences in returns to households’ endowments.     

Effect of Parental Migration on the Academic Performance of Left Behind Children in North Western China

China’s rapid urbanisation has induced large numbers of rural residents to migrate from their homes in the countryside to urban areas in search of higher wages. As a consequence, it is estimated that more than 60 million children in rural China are left behind and live with relatives, typically their paternal grandparents. These children are called Left Behind Children (LBCs). There are concerns about the potential negative effects of parental migration on the academic performance of the LBCs that could be due to the absence of parental care. However, it might also be that when a child’s parents work away from home, their remittances can increase the household’s income and provide more resources and that this can lead to better academic performance. Hence, the net impact of out-migration on the academic performance of LBCs is unclear. This paper examines changes in academic performance before and after the parents of students out-migrate. We draw on a panel dataset collected by the authors of more than 13,000 students at 130 rural primary schools in ethnic minority areas of rural China. Using difference-in-differences and propensity score matching approaches, our results indicate that parental migration has significant, positive impacts on the academic performance of LBCs (which we measure using standardised English test scores). Heterogeneous analysis using our data demonstrates that the positive impact on LBCs is greater for poorer performing students.
