Expenditure patterns and elasticities of rural households sampled in two communal areas of KwaZulu-Natal

Expenditure patterns among a sample of 99 rural households in two communal districts in KwaZulu-Natal were investigated to determine the potential impact of a widespread income shock on household expenditure. The results showed expenditure elasticities of close to unity for food. Low elasticities were found for staple foods. Elasticities for meat, meat products and poultry were close to unity, while horticultural products showed the greatest potential for demand growth within the food category. Of the statistically significant commodity categories, expenditure elasticities for durables, housing and transport were more than double those estimated for the aggregate food category. For consumer items, the district expenditure elasticities were estimated to be 0,76 and 0,71, while expenditure on social obligations would not increase with rural incomes. Wealthier households (the top expenditure decile) have a greater propensity for increased expenditure on transport, while poorer households show a greater propensity for increased expenditure on housing and durables. Although agriculture has the potential to generate widespread growth in rural incomes, the preference for manufactured goods casts some doubt on the strength of consumption multipliers for locally produced farm and non-farm goods in rural KwaZulu-Natal.     

Estimating flexible consumption functions for urban and rural households in China

There are few comprehensive studies of household consumption in China that covers all commodities due to data restrictions. This prevents the calculation of inequality indices based on consumption. This lack of coverage also makes analysis of policies that affect consumption difficult; economy-wide models used for analysis often have to employ simple consumption forms with unit income elasticities. We estimate a translog demand system distinguished by demographic characteristics, giving price and income elasticities that should be useful for policy analysis. We estimate separate functions for urban and rural households using household expenditure data and detailed commodity prices (1995–2006). This allows future analysis of social welfare and inequality based on consumption to supplement existing studies based on income. To illustrate an application of the model, we project consumption composition based on projected prices, incomes and demographic changes – aging, education improvement and urbanization.     

Household consumption patterns and the consumer price index,England, 1260–1869

Existing long-run consumer price indices for England rely on a fixed consumption basket. Here we construct a methodologically improved, chained-Laspeyres price index for ordinary households based on their changing expenditure patterns between 1260 and 1869. Rather than offering a revisionist perspective on long-run costs, it confirms the broad accuracy of existing indices for the pre-industrial period. The dominant dependence of the key items of expenditure on agricultural, particularly arable, prices explains this finding. The industrial period introduced a new dynamic. The shift in household expenditure towards imported groceries and manufactured goods allowed for more substitution in response to relative price and income changes. Adding the current series to those chained-Laspeyres indices available for later periods provides a CPI for ordinary households in England over nearly eight centuries; from 1260 to the present day.     

An investigation into food-away-from-home consumption in South Africa

Food policy that ignores food-away-from-home (FAFH) in a developing country like South Africa will be misleading given changes in demand for food over time. This study contributes to our understanding of the factors that influence the demand for FAFH in South Africa. Using panel data from the Income and Expenditure Survey, this study analyses the effects of income and socio-demographic variables on FAFH expenditure using a double-hurdle model. The results show that small-sized households headed by younger white females/males and living in an urban settlement are most likely to purchase FAFH while male-headed households spend more than female-headed households. Furthermore, income of the household head is an important determinant of household FAFH expenditures. The income elasticity of expenditure on FAFH is inelastic and a normal good. The small size of the participation elasticities means that growth in the FAFH sector will be driven by households with existing expenditure.     

Food Demand Characteristics in Uganda: Estimation and Policy Relevance

Uganda was highly successful in reducing poverty over the past two decades but made little progress towards household food security. This underlines the need for designing food security interventions customised for household‐specific needs and behaviours. This study estimates Ugandan household demand behaviour with a focus on food consumption paying particular attention to household‐specific characteristics. The results show that preferences to increase calorie‐dense staple consumption, likely associated with food energy deficiency, extend far beyond the percentage of rural Ugandans officially deemed poor. Price elasticities indicate that poor rural households are largely well positioned to compensate staple price increases by substitution as long as they are not already concentrated on the cheapest foods. This flexibility applies less to urban households. The estimated demand elasticities generally vary widely between rural and urban households and depend on expenditure levels. Household‐specific characteristics have significant, sometimes pronounced, influences on demand, as do seasons and regions. The results reflect highly differentiated demand behaviour, which can be utilised to improve the design and evaluation of food security interventions.     

Rural–urban differences in parental spending on children's primary education in Malawi

Using Malawian data, this paper answers two interrelated questions: are there rural–urban differences in the factors that influence the probability that a household spends or does not spend on own children's education; and are there rural–urban differences in the factors that affect educational expenditure if a household decides to spend? Computed elasticities indicate that spending on education by rural households is more sensitive to changes in income compared with urban households, suggesting that spending on education in rural areas is a luxury good. In both areas, a mother's employment and education has a larger impact on spending compared with those of a father. Urban households compared with their rural counterparts are more sensitive to the quality of access to primary schools. We find no evidence of gender bias in school spending in urban areas, but rural households exhibit bias in favour of boys.     

Housing demand in Shanghai: A discrete choice approach

In this study we apply a random utility modeling framework to analyze housing demand in the city of Shanghai. A Multinomial Logit Model taking account of latent choice sets is employed to investigate the impact of household characteristics, such as income, size and age composition, on the choice of dwelling, specified by location, size and unit price. In addition to the price and income effects on housing demand, the model identifies a quality indicator for dwelling attributes, which can be interpreted as the mean attractiveness in a money metric measure.The data used in this study are cross-sectional survey data. The estimated model is used to calculate demand elasticities and demand probabilities, for selected groups of households and types of dwellings. Among the results can be noted that the price–income ratios, the age composition and size of household are all important determinants of the demand. The impact of income distribution on housing demand is also studied.     

Income and consumption inequality in China: A comparative approach with India

We analyse income and expenditure distribution in China in a comparative perspective with India. These countries represent extreme cases in the relationship of inequality to both wellbeing indicators. Income is more highly concentrated than expenditure in India, especially at the top of the distribution. Both types of inequality are similar in China, although expenditure is more unequally distributed than income in urban areas. China has a much stronger correlation in individual ranks and levels between the two wellbeing distributions. As a result, expenditure inequality is higher in China than in India, but income inequality much lower. This results partially from differences in population composition, such as China being more urbanized and having smaller households, but mostly from differences in conditional income distributions, especially by attained education of the household head. We show that hybrid measures of wellbeing combining income and expenditure can be useful for such cross-country comparison.     

Socio-demographic dynamics and household demand

The relationship between household characteristics and household expenditure in the United States is explored. "The basic hypothesis of this paper is that socio-demographic characteristics of households are important determinants of their expenditure patterns as are price and income variables."     

The Invisible Hand of Rain in Spending: Effect of Rainfall‐Driven Agricultural Income on Per Capita Expenditure in Ghana

This paper uses a nationally representative household pseudo‐panel dataset for Ghana, a rain‐fed agriculture economy, to investigate whether there is a positive relationship between rainfall‐driven agricultural income and household per capita expenditure. By using the Two Stage Least Squares Instrumental Variable (2SLS‐IV) estimator, it is found that a fall in rainfall‐driven agricultural income leads to a decrease in per capita expenditure. The results show that the gender and the locality of the household head matter in the response of per capita expenditures to rainfall‐driven agricultural income. Female‐headed and rural households are more vulnerable to rainfall‐driven agricultural income changes. The expenditure disaggregation indicates that female‐headed households significantly reduce per capita non‐food expenditure in times of rainfall‐induced agricultural income decrease whilst the response of male‐headed households focuses more on reducing per capita food and remittance expenditures.     

THE DEMAND FOR FOOD IN SOUTH AFRICA1

Food consumption is an important issue in South Africa, given its relation to poverty and deprivation. With the pressing need to increase food security, understanding the determinants of the demand for food and having some estimates of the likely impact of price and income changes has become a vital task. There is, however, surprisingly little economic research on this topic and almost none in recent times. This paper provides a comprehensive empirical analysis of the demand for food in South Africa for the years 1970‐2002. It moves beyond the usual static modelling approach in using a general dynamic log‐linear demand equation and a dynamic version of the almost ideal demand system, to provide estimates of the short‐ and long‐run price and expenditure demand elasticities.     

Block Rate Pricing of Water in Indonesia: An Analysis of Welfare Effects

Block rate pricing of piped water in Indonesian cities has a progressive structure: the marginal price paid increases with the volume of demand. This paper estimates household water demand in Salatiga city using the Burtless and Hausman model, and finds that its distribution is not unimodal—that data cluster around kinks. The main estimation results are a price elasticity of approximately–1.2 and an income elasticity of 0.05. These elasticities are mutually dependent. The estimated model is used to investigate the social welfare consequences of a shift to uniform pricing. The principal beneficiaries would be large households, which are not necessarily wealthy. While replacing the complex rate structure by a uniform marginal price would have positive effects on average welfare, the equity consequences would be small. To improve equity, water companies could reduce installation fees, giving low-income households access to water connections, or reinvest profits in network expansion to unserviced areas.     

The role of public pensions in income inequality among elderly households in China 1988–2013

Using data from the Chinese Household Income Project surveys for 1988, 1995, 2002 and 2013, we investigate the role of public pensions in income inequality among households with elderly members across two decades of pension policy reforms. We examine the distribution and role of public pensions at a national level and analyse the evolution of the contribution of public pensions to national income inequality across a much more extended time period than earlier studies, which have generally focused on regional changes over short periods. Our findings suggest that public pensions have become the most important source of income for households with elderly members on average in China, but the distribution of pension income is highly unequal, with a Gini coefficient of 0.74 in 2013. Public pension income has been the largest source of income inequality for elderly households since 2002 and contributed to more than half of total income inequality in the most recent year of the survey. This finding is robust against variations in the income inequality measures used. Additionally, our analysis suggests unequal distribution of pension benefits is the primary driver of pensioners' income inequality. Among several hypothetical policy changes, ensuring a minimum pension benefit for all existing pensioners seems to be the most fiscally effective option in reducing income inequality, with a 0.8% reduction in the Gini coefficient for a 1% increase in public pension expenditure.     

When More Poor Means Less Poverty: On Income Inequality and Purchasing Power

We show theoretically that the poor can benefit from price changes induced by higher income inequality. As the number of poor increases, the market for products aimed toward the poor grows, and such products become more profitable. As a result, there are circumstances where an increase in income inequality associates with higher purchasing power of the poor. Using cross‐country data on the price of one kilogram of rice and the price of a Big Mac hamburger, we confirm a negative association between income inequality and the price of inferior goods, robust to the inclusion of a large set of control variables. Results are also robust to a first difference specification and to a two‐stage instrumental variables approach. Examining economic well‐being, it is thus important to analyze not only the incomes of households, but also the prices of the products and services that they buy.

In Data We Trust? An Analysis of Indonesian Socioeconomic Survey Data

What if a popular dataset that has generated a large amount of literature has been misunderstood and has led to misleading inferences? This paper examines household expenditure data from the Indonesian National Socio-economic Survey (Susenas), which started more than 50 years ago. Appropriate use of Susenas data for policy analysis requires an understanding that the survey’s expenditure variable does not measure true out-of-pocket expenses, because it includes subsidies received by households when obtaining goods and services. We also highlight an abrupt change in the survey instrument that occurred in 2015, when the reference period for certain items was extended. For health items, this generated a change in the expenditure series that can be misinterpreted as being the result of a social health insurance reform introduced in 2014 to lower the health care burden on households. Accordingly, we propose a way to account for this artificial expenditure movement in Susenas.     

Household satisfaction: Past,present and future perspectives

In the past two decades South African quality of life has been measured at the individual level in nationwide surveys and studies of special groups using happiness and satisfaction measures. In 1993 the Southern Africa Labour and Development Research Unit (Saldru) pioneered a satisfaction measure to capture subjective well‐being at the household level for the Project for Statistics on Living Standards and Development (PSLSD). The article assesses the usefulness of the new indicator by comparing present household satisfaction with individual‐level satisfaction trends and with PSLSD measures of past and projected future satisfaction and household income and expenditure. It is concluded that the household satisfaction measure is a useful social indicator in that it yields consistent and readily interpretable results and is sensitive to income and expenditure differentials. In confirmation of findings from a recent cross‐national study, the higher income households in the Saldru study reported higher levels of perceived well‐being.     

Impacts of the COVID-19 crisis on single-person households in South Korea

Using nationally representative income and expenditure data from South Korea, we show that single-person households suffered a much greater decrease in household income and expenditure compared to multi-persons households during the COVID-19 pandemic in 2020. Negative effects on income were largest for the single-person households in ages 50—64, mostly driven by decreases in earned income rather than business income. There was no corresponding decrease in consumption expenditures, however, other than on transportation expenditure for young men. Notably, there were significant decreases in non-consumption expenditures that are related to formal and informal consumption-smoothing mechanisms, such as spending on insurances, pensions, and household transfers. Our findings highlight the disproportionately negative effects of the COVID-19 pandemic on the middle-aged single-person households. With reduced spending on consumption-smoothing mechanisms, this group is likely to be even more vulnerable to negative income shocks in the future.     

The Influence of Demographics and Household-Specific Price Indices on Consumption-Based Inequality and Welfare: A Comparison of Spain and the United States

Previous research has suggested that inequality is lower in Spain than in the United States when it is based on income. For the present article, both inequality and social welfare are examined, with household consumption expenditures used as a proxy for household welfare. For tractability, equivalence scales depended only on the number of people in the household. Household-specific price indices were used to express the 1990-1991 expenditure distributions in 1981 and 1991 winter prices. Our results reveal that inequality and welfare comparisons are drastically different for smaller and larger households. When all households are considered, the two-country comparison suggests that the income inequality ranking can only be maintained for expenditure distributions when economies of scale are small or nonexistent. However, welfare is always higher in the United States than in Spain. Because inflation during the 1980s in both countries was essentially distributionally neutral, all results appear to be robust to the choice of time period.     

Effects of farmer support programmes on consumption and investment

Effects of farmer support programmes (FSPs) of the Development Bank of Southern Africa on consumption and investment are determined by utilising cross‐sectional survey data from the Mashamba and Khakhu areas of the Venda homeland in South Africa. Income elasticities indicate that the demand for goods (staple food) produced by households increases less than the demand for purchased goods. A discriminant analysis of surplus versus deficit producers indicates that surplus production is associated with farmers who participate in the FSP (ie farmers using chemical fertilizers and purchasing inputs on credit). The existence of soil erosion, availability of ploughing services, expenditure on transport education, medical and personal items, and the existence of a savings account also play important roles in explaining the difference in production performance between surplus and deficit food‐producing households.
