Variety,prices and food status in low-income households

The basic premise of this paper is that a household receives utility directly from the status of a food composite good which is created by combining a household's skill and creativity in preparing foods, other inputs, and the kinds and amounts of foods available. We proceed to investigate the factors influencing the demand for and prodcution of this composite good. The demand for food status in influenced most by the following characteristics: race, education, houshold size, homeownership, region of household residence and income. Direct price effects were minor. Estimates of a food status production function imply that the production of food status is not much a matter of the quantities of foods consumed but rather the types of food purchased (variety) and the creativity of the homemaker.     

Is power more evenly balanced in poor households?

The structure of intra-household allocation is crucial to know whether a transfer from a rich household to a poor one translates into a transfer from a rich individual to a poor one. If rich households are more unequal than poor ones, then a progressive transfer among households reduces intra-household inequality, hence inequality among individuals. More specifically, two conditions have to be satisfied for extending Generalized Lorenz judgments from household level to individual one. The fraction of the couple's expenditures devoted to goods jointly consumed should decrease at the margin with the couple's income as well as the part of private expenditure devoted to the disadvantaged individual. This double concavity condition is non-parametrically tested on the French Household Expenditure Survey (2000). It is not rejected by the data and supports the view that power is more evenly distributed in poor households.     

Multi-family households in a labour supply model: a calibration method with application to Poland

Models of cooperative and noncooperative behaviour opened the household ‘black box’ and allowed for individual treatment of partners in couples. However, labour supply literature has so far largely ignored a broader issue – the distinction of single versus multi-family (‘complex’) households. We propose a method to account for multi-family household structure by borrowing from recent applications of the collective model to identify the degree of sharing. We assume that each household is characterized by a between-family sharing parameter, which is calibrated on estimated preferences, observed labour market status and other characteristics. We apply the method to Polish labour market data.     

Recovering Hicksian Consumer Surplus within a Collective Model: Hausman's Method for the Household

The purpose of this paper is to describe the implications of the collective model of household behavior for the methods used to estimate the economic value of non-marketed environmental resources. After demonstrating how the separability restrictions inherent in the collective model allow individual preference and household income allocation choices to be distinguished, the paper demonstrates how the framework can be used to recover Hicksian consumer surplus. An algebraic example is used to illustrate how the framework can be used in valuing environmental resources.     

Collective consumption and welfare

Abstract.  In this paper, we present a collective model of household demand based on Pareto‐efficiency. In addition, we suppose that (a) each household member is egoistic and consumption is purely private, (b) there is a set of distribution factors and (c) there is one exclusive good. Then we derive the testable restrictions that are implied by this theoretical setting and show how welfare comparisons at the individual level can be performed. JEL classification: D11     

Does local social capital deter labour migration? Evidence from rural China

This article empirically investigates the effect of local social capital on job-related migration in rural China. A household’s social ties in the region of origin, which we refer to as local social capital, may deter migration, because local social capital is location specific and an individual cannot benefit from it if s/he migrates. In view of Chinese gift-giving culture, we use household expenses on wedding gifts for family members outside household, relatives and friends as a proxy for local social networks. Based on the data from the China Health and Nutrition Survey, we find that in rural China local social networks have a significantly negative effect on migration. The IV results suggest that a 10% increase in wedding gifts expenses results in roughly a 1.1 percentage points decrease in migration probability.     

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.     

Efficient Intra-Household Allocations and Distribution Factors: Implications and Identification

This paper provides an exhaustive characterization of testability and identifiability issues in the collective framework in the absence of price variation; it thus provides a theoretical underpinning for a number of empirical works that have been developed recently. We first provide a simple and general test of the Pareto-efficiency hypothesis, which is consistent with all possible assumptions on the private or public nature of goods, all possible consumption externalities between household members, and all types of interdependent individual preferences and domestic production technology. The test is proved to be necessary and sufficient. We then provide conditions for the identification of the sharing rule and the Engel curves of individual household members for a variety of different observational schemes.     

How relative income affects work hours preferences

In this article, we look at explanations for why people want to change their working hours. We focus on the role of income and differentiate between the effect of household income, personal income and self-perceived relative income. Using Flemish data on 1435 workers, we perform binary logistic regressions in which we compare those who are over- or underemployed with those who are currently working their preferred number of hours. Our results show that the desire to work fewer hours is mostly related to a bad work–life balance, while the wish to increase working hours is associated with relative income rather than absolute income. Based on our findings we recommend governments to not only focus on increasing flexibility at the individual level but to also consider these positional effects by taking measures (e.g. decreasing the duration of the standard working week) at the population level.     

THE HOUSEHOLD DISTRIBUTION OF GOVERNMENT SERVICES FOR AGRICULTURE AND EDUCATION IN PENINSULAR MALAYSIA IN 1974

The paper reports on several results from a comprehensive study of the household incidence of public expenditure in Peninsular Malaysia in 1974. The results for education show a pro-poor distribution of expenditure when measured as a share of household income. Using however the criterion of each according to his needs (that is the number of school-age children per household) reverses this outcome. In agriculture, because of the importance of land settlement, benefits from public expenditure distribute predominantly in favor of the poor.
The research differs from the usual study of this kind in that individual government outputs such as school years, or fertilizer loans, were defined, and in the case of education their unit costs estimated and their distribution across households measured. In the case of education, both the costs of services from capital and the households' out-of-pocket educational costs were added to the current subsidies. As one consequence, it was seen that total expenditure for education in Malaysia exceeds one-eighth of GNP, nearly double the conventional estimate. Equally important, for the poor the burden of private costs for education even within a public system were seen to be very high.
The contrasts between the strong results for education, a broad based social service, and the less conclusive results for agriculture, an economic service which impacts directly on production, were instructive in suggesting the limitations of such research in measuring the effects of government budget activity on distribution.     

SELF‐REPORTED ECONOMIC CONDITION AND HOME PRODUCTION: INTRA‐HOUSEHOLD ALLOCATION IN ITALY

This paper applies a collective model of intra‐household welfare distribution using individual self‐reported data. The model accounts for household production, and self‐reported information on economic condition is used to identify the sharing rule governing the bargaining process in the family. The theoretical framework implies a broad concept of full income, which includes household production as time allocated to domestic activities. We find that self‐reported data on economic status are useful in recovering individual shares of household income and that both wages and non‐strictly‐economic individual variables play an important role in the bargaining process determining the sharing rule in Italy.     

Household tax evasion

Household members share public goods and make intra-household transfers. We show how these features of the household interact with the tax evasion decision, and identify the dimensions in which household evasion differs from individual evasion. In the model we present two members of a household choose how much to contribute to a household public good and how much self-employment income to evade. We are interested in how different evasion possibilities interact with the contribution decisions to the household public good and the role of income transfers within the household. We show the household evasion decision differs from the individual decision because it affects the outcome of the household contribution game. When household members are taxed as individuals neutrality applies when choices are not constrained. If the evasion level of one household member is constrained then an income transfer can generate a Pareto improvement. When the household members are jointly taxed there is a couple constraint on strategies and corner solutions can emerge.

Household Intertemporal Behaviour: A Collective Characterization and a Test of Commitment

In this paper, a formal test of intra-household commitment is derived and performed. To that end, two models of household intertemporal behaviour are developed. In both models, household members are characterized by individual preferences. In the first formulation, household decisions are always on the ex ante Pareto frontier. In the second model, the assumption of intra-household commitment required by ex ante efficiency is relaxed. It is shown that the full-efficiency household Euler equations are nested in the no-commitment Euler equations. Using this result, the hypothesis that household members can commit to future allocations of resources is tested using the Consumer Expenditure Survey. I strongly reject this hypothesis. It is also shown that the standard unitary framework is a special case of the full-efficiency model. However, if household members are not able to commit, household intertemporal behaviour cannot be characterized using the standard life-cycle model. These findings have two main implications. First, policy makers can change household behaviour by modifying the decision power of individual household members. Second, to evaluate programmes designed to improve the welfare of household members, it would be beneficial to replace the standard unitary model with a characterization of household behaviour that allows for lack of commitment.     

THE STRUCTURE OF THE EARNINGS DISTRIBUTION: HOW ARE HOUSEHOLDS AND INDIVIDUALS RELATED?*

This paper investigates the links between individual and household distributions of earnings. Using a sample of 1991 data from the UK, considerable complexity is uncovered in the structure of the household earnings distribution. This is due to heterogeneity of earners and positive ‘clustering’ of earners within households. The structure of the clustering behaviour of earners for different household types is estimated, and the contribution of clustering to overall earnings inequality is evaluated. Perhaps surprisingly in view of the observed clustering behaviour, it is found that clustering has reduced overall inequality, although the mean-adjusted distribution of individual earnings is insignificantly different from the distribution of household earnings.     

Optimal diversification and risk-taking: a theoretical and empirical analysis

Among the justifications for capital property income received by private households is that it is a ‘return to risk-taking’. However, portfolio diversification provides an obvious means toward the reduction of risk. Moreover, it is widely believed that the wealthier the household, the more diversification it practices: the larger tends to be the proportion of its total portfolio allocated to publicly traded stock, and the larger tends to be the number of individual stock issues included in its portfolio. Using a simple ‘homogeneous securities’ model, explicit functional forms are obtained for both the optimal proportion of the portfolio allocated to stocks, and the optimal number of individual stock issues in the portfolio. Empirical evaluation of these theoretical results, using a dataset derived from the 2004 Survey of Consumer Finances (SCF), lends substantial support to the model. Applying these empirical results, it is found that as household capital wealth increases, expected capital income increases while simultaneously a reasonable risk indicator (the probability of incurring a negative return on the capital portfolio) decreases owing to the higher level of portfolio diversification. This indication casts significant doubt on the ‘return to risk-taking’ justification for capital property income received by wealthy private households.     

ECONOMIC INCENTIVES FOR DIETARY IMPROVEMENT AMONG FOOD STAMP RECIPIENTS

Most Americans need to consume more fruits, vegetables, and dairy products. This need is particularly acute among low‐income individuals. This study examines the cost‐effectiveness of two economic policies that use alternative policy levers available within the Supplemental Nutrition Assistance Program (formerly Food Stamp Program) to increase consumption of these under‐consumed foods. Data from three nationally representative surveys are used to estimate demand elasticities, marginal propensity to spend on food out of food stamp benefits, and consumption amount of and spending on under‐consumed foods among food stamp recipients. Results suggest that a 10% price subsidy would curtail consumption deficiencies by 4%–7% at an estimated cost of $734 million a year. When the same $734 million is used to finance food stamp benefits, consumption deficiencies are predicted to narrow by only 0.35%–0.40%. (JEL C34, D12, Q18)     

Fairness and inequality tolerance: Evidence from the Life in Transition Survey

This paper examines the link between inequality and individual well-being using household survey data from 27 transition economies, where income inequality increased considerably since 1989. A test of inequality aversion in individual preferences that draws on the Fehr and Schmidt (1999) specification of inequality aversion is proposed, and the difficulties of implementing it in a non-experimental setting are discussed. Estimates based on this model confirm aversion to inequality among individuals both in the pooled sample and separately among the EU and non-EU countries. The Gini index, on the other hand, is unable to capture this negative effect of inequality on well-being. Notably, inequality aversion is not intrinsic. Rather, it appears to be tied to a concern with the fairness of the institutions underlying the distribution of fortunes in society. The evidence is suggestive of inequality of opportunity driving attitudes toward overall inequality.     

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.     

Estimating inequality in the distribution of welfare using demand models

In this paper two demand models with general household equivalence scales (GES) are estimated. These GES are identifiable, since they have the independence of base utility (IB) or equivalence scales exactness (ESE) property. Estimates of household characteristics adjusted income can then be calculated relative to a specific household type. This “individual equivalent income (IEI) is then used to calculate measures of inequality in the distribution of welfare. As more than one model is estimated, the sensitivity of these estimates to model specification changes can be considered. Comparisons are also made to estimates of inequality based on household income. It is found that absolute inequality is sensitive to model specification, but relative inequality is not. This is true using indices of inequality of the Atkinson (1970), Kolm (1976a,b) and Sen (1973) type, or more general measures of inequality based on estimates of Lorenz curve decile ordinates, constructed using methods introduced by Beach and Davidson (1983). Thus, if absolute measures of inequality are required, these results suggest some further research is required to determine a class of models which is less sensitive to model specification error. However, if only relative measures of inequality are needed, then estimates of inequality appear to be very robust to the choice of model specification.
