Household Income,Demand, and Saving: Deriving Macro Data With Micro Data Concepts

We develop adjustments to align the NIPA measures of key household variables with cash flow concepts that reflect household budgets and actual demand generated by households. The adjusted variables have substantially different behaviors across time than NIPA measures of household spending and saving. Furthermore, household income aggregated from micro data sets like the CPS, SCF, and PSID differs significantly from NIPA personal income. But the micro survey data likely reflect cash flow concepts rather than NIPA definitions. Indeed the adjusted cash flow measure of income eliminates much of the gap between micro data income variables and NIPA household income.

ASPECTS OF THE OFFICIAL NATIONAL INCOMES TABLES OF FIJI*

This paper describes and examines three particular features of the official national income tables recently published by the Fiji Government. The need of development planners for a comprehensive set of national accounts incorporating detailed information relating to central government current expenditure, the operations of the private business sector, and the rural household economy has assumed special importance. The uses and limitations to the information contained under these specific headings is discussed and throughout an emphasis is placed on the need for the adoption of consistent and systematic methods of collection and estimation procedures to facilitate planning and decision making. As aids to more detailed interpretation and analysis, the features described are considered to be of general interest to other developing countries.     

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.     

Back to Engel? Some evidence for the hierarchy of needs

Using UK household expenditure data spanning over four decades (1960–2000), this paper employs Engel’s needs-based approach to analyzing household expenditure patterns and finds evidence for the existence of a stable hierarchy of expenditure patterns at low levels of household income. Second, we investigate how rising household income influences the manner in which total expenditure is distributed across Engel’s expenditure categories. Our results suggest that i) total household expenditure is distributed across Engel’s expenditure categories in an increasingly even manner as household income increases and ii) over time, there has been an acceleration in the rate at which household expenditure patterns become diversified as household income rises. Finally, we consider how the shape of Engel Curves may help shed light on the relationship between goods and the underlying needs they serve.     

THE DISAGGREGATION OF THE GIN1 COEFFICIENT BY FACTOR COMPONENTS AND ITS APPLICATIONS TO AUSTRALIA

This paper demonstrates the proper use of the disaggregation of the Gini coefficient by factor components by deriving a formula of the elasticity of the Gini coefficient with respect to specific income components. The method is then applied to Australian household expenditure survey data to find the effects of various components of income on overall income inequality. The results are important in examining the effects of growth in specific components on the overall inequality and hence in policy decisions with respect to redistribution of income.     

STUDIES OF INCOME REDISTRIBUTION IN DENMARK

Income redistribution studies on the macro–economic level have been undertaken in Denmark for the years 1938–39, 1949, 1955, and 1963. By use of national accounts figures and all other available statistics, it was on certain assumptions possible to distribute public sector income and expenditure by income groups.
A quite different approach is used in a Danish redistribution study on the micro-economic level for 1971, which relies solely on the comprehensive data from the family budget survey for that year. Unfortunately this study only relates to employee households.
This paper deals with the 1963 and 1971 studies. First it describes and discusses the differences in methodology between the two studies and indicates some ideas for future studies in this field in Denmark. In the following sections some main results of the two studies are given, briefly for the 1963 study and more comprehensively for the 1971 study. The studies show the great and growing strength of the policy of redistribution through public sector income and expenditure in Denmark.
It is the opinion of the authors that the appearance of redistribution studies based on comprehensive family budget surveys makes for a substantial improvement of redistribution figures, and that the purely micro-level frame of reference makes it possible to interpret the results in a more satisfactory way than before. Furthermore, the appearance of detailed input-output based national accounts data should bring about further improvements in redistribution figures through better data on indirect taxes and subsidies as well as supporting data which are necessary to link the micro and macro levels in a consistent way.     

The Political Economy of Policy Reform in the Philippines: 1992–1998

Accurately measuring Turkey's informal sector is important for policymaking. We utilize household income‐expenditure surveys to examine this sector's income underreporting. The Pissarides‐Weber approach hypothesizes that data would reflect such underreporting as “excess food consumption”. Our results suggest informal sector members spend more than their formal sector counterparts with comparable reported income levels. Using this information, we estimate the average size of the true informal sector to be about 1.25 times the official estimate. The informal sector accounts for around 83% of officially reported disposable income. Therefore, true Turkish disposable income is (25%)?(83%), roughly 21% larger than the officially estimated magnitude.     

An economic profile of peasant perpetrators of genocide: Micro-level evidence from Rwanda

This paper presents the results of a research project in which we have traced 350 Rwandan households who were part of a rural household survey before the Rwandan genocide (1994). Economic, demographic and agricultural data from an extensive 1989–1992 survey can be linked with the condition of the household at the time of the Genocide Transition Survey (2000). This allows us to study the fate of the household members during the genocide. Our results show that age, sex, the sex of the head of the household, the size of rented land, off-farm income, gross household income and farm-level anti-erosion investment significantly determine the probability of a household member to become a perpetrator of genocide. These results are interpreted in the political economy of Rwanda.     

Testing exact aggregation in income and household characteristics: the effects of aggregation across goods

Exact aggregation in income and household characteristics are tested using Canadian cross-sectional microdata. Over 100 data sets of homogeneous households are used, making it possible to conduct a large number of independent hypothesis tests. Tests are also conducted to determine whether the homogeneous household groups can be grouped into more heterogeneous data sets. Six different kinds of demand systems are estimated to ensure the robustness of the results to separability/aggregation structure.Exact aggregation in income, family size, region of residence and housing tenure status are strongly rejected, but exact aggregation in age of head of household is not. Restrictions which would allow pooling of households of different sizes, regions and tenure status are also strongly rejected. The test results exhibit a little sensitivity to the expenditure aggregates used, but not to the extent that the results would be different.The results imply that aggregate demand functions which use time series data should include many statistics from the joint distribution of income and household characteristics. In addition, when using data at the micro-level, the amount of heterogeneity in households' behaviour is much greater than usually assumed. This calls for the use of much more homogeneous household groups in the estimation of demand models than are typically employed.     

Household composition and the measurement of disparity in levels of living

The importance of household composition in the analysis of inequalities in income distribution based on household survey data is illustrated using data for rural Punjab, India, from the 25th round of the National Sample Survey. The study also reveals that distribution of household consumption expenditure, if not adjusted for household size and composition effects, gives biased measures of the extent of true inequality.     

农业产业化对农民收入和农户行为的影响--以山东省龙口市为例

农业产业化是当今中国农业发展的热点，但产业化经营究竟能在多大程度上促进“三农”问题的根本转变，目前仍很少有人进行定量研究。文章以农业产业化起步较早的山东省龙口市为案例，通过生产调查和统计资料分析，对该问题做了初步研究。结果表明：尽管龙口市的乡村工业发展迅速且占据了农村经济的绝大部分，但与农民人均纯收入增长关系最为紧密的仍然是农业产业，其次才是农村第二、第三产业，这一结果应归功于农业产业化的发展。农户在家庭劳动力分配时，年老人趋向于从事农业生产，年轻人趋向于从事非农生产，许多农户将自家的劳动力投入到非农产业，同时又雇佣外地劳力从事自家的农业生产。     

Inequality and volatility moderation in Russia: Evidence from micro-level panel data on consumption and income

We construct key household and individual economic variables using a panel micro data set from the Russia Longitudinal Monitoring Survey (RLMS) for 1994–2005. We analyze cross-sectional income and consumption inequality trends and find that inequality decreased during the 2000–2005 economic recovery. The decrease appears to be driven by falling volatility of transitory income shocks. The response of consumption to permanent and transitory income shocks becomes weaker later in the sample, consistent with greater self-insurance against permanent shocks and greater smoothing of transitory shocks. Finally, expenditure and income inequality in Russia are not far apart.     

City size and household food consumption: demand elasticities in Spain

Are food price elasticities different across city sizes? The aim of this article is to estimate expenditure and own-price elasticities for 10 aggregated food product groups using the Spanish Household Budget Survey for the year 2010. These products are the ones for which the survey provides information regarding prices and quantities, thus allowing the application of an Almost Ideal Demand System (AIDS) model with censored data. The estimation procedure allows not only comparisons to be made among households with different levels of income, but also the contribution of residence characteristics to variations in demand. The results confirm that the size of the city in which the household resides has a similar significant and relevant effect on consumption patterns as family income level. This is especially clear with own-price elasticities. In Spain, large central cities show a greater response to price changes than smaller cities or rural peripheral areas.     

Determinants of food consumption in rural Sierra Leone: Application of the quadratic expenditure system to the consumption-leisure component of a household-firm model

This paper reports the application of a quadratic expenditure system with demographic variables to the household consumption-leisure choice component of a household-firm model. A system of seven commodities is estimated: including five foods, non-food and leisure. Appropriate for such a level of disaggregation a demand system is used, the Quadratic Expenditure System, which allows for a flexible relationship between full income and commodity expenditures without sacrificing parsimony in parameters. Demographic data on households are explicitly incorporated into the model allowing for a richer specification than can be achieved by using per capita variables. The data are from a cross-section survey of households in rural Sierra Leone. Price variation exists by region, permitting estimation of a complete demand system. Engel curves are found to be significantly non-linear, with marginal expenditure on rice, the major staple, declining with higher income. Most foods are found to be reasonably price responsive with sizeable own price substitution effects, declining with higher income. Aggregate labor supply is found to be price inelastic.

我国贫困地区农村居民消费需求影响因素研究

本文基于2005年国家级贫困县农村居民入户调查数据,实证分析了收入、消费环境、消费观念以及人口学特征等因素对我国贫困地区农村居民消费需求的影响。研究结果表明,居民所在村通公路会增加农民的消费支出;家庭规模的扩大会导致居民消费支出的减少;如果居民家庭中有成员在城市工作,其消费观念的变化会导致其消费支出发生变化;在我国贫困地区,汉族居民的消费支出水平高于少数民族居民;家庭结构对居民消费支出亦有显著影响。在此基础上,本文提出改善我国贫困地区农村居民消费水平的措施,包括提高农村居民的收入、加快农村地区基础设施建设、改变农村居民的消费观念、注重对少数民族居民的政策扶持等。     

A MICROCONSISTENT EQUILIBRIUM DATA SET FOR CANADA FOR USE IN TAX POLICY ANALYSIS

In this paper we describe a micro consistent data set for Canada for 1972, assembled with general equilibrium tax policy analysis in mind. We stress the methodology used and in a number of tables report its main features.
In the data set the separate detail contained in input-output transactions tables, national accounts, household income and expenditure data, taxation statistics, foreign trade statistics, flow of funds and other sources is adjusted for mutual consistency. The final result is a micro consistent data set in which demands equal supplies for all products, zero profit conditions hold for industries and all agents' demands satisfy their budget constraints.
The motivation for data assembly is the currently widely used practice of calibrating "empirical" general equilibrium models so as to exactly reproduce a base year data observation as an equilibrium model solution. This procedure enables empirically based models to evaluate counterfactual equilibria in a way which corresponds to comparative static analysis in theoretical literature.
More detail on the data set is available on request in appendices deleted from the published version of this paper due to space constraints.     

MEASUREMENT OF THE DISTRIBUTION OF WEALTH IN CANADA

The only periodic data available in Canada on the asset holdings and net worth of the household sector are data collected through a series of household surveys originally initiated in 1954. Some limited data on the holdings of financial claims by the personal and unincorporated business sector are available from flow of funds work. Data are unavailable for estimation from estate tax returns.
The scope of the surveys has been expanded substantially so that the most recent survey obtained a very comprehensive list of asset holdings. The experience with Canadian surveys has been similar to that of other countries; surveys appear to underestimate asset holdings although the estimates are more reliable for widely held assets than for assets with a very skewed distribution. Nevertheless, the surveys appear to trace the accumulated distribution of personal savings over time to a considerable degree and provide useful cross-sectional trend data.
Canadian data show that wealth is more unequally distributed among family units than is income although wealth appears to be more equally distributed between income groups than is income. Wealth is also very unequally distributed within the same income group. Over time, there appears to have been some movement towards a more equal distribution of asset holdings between income groups.     

An econometric application of the theory of the farm-household

Employing a Cobb-Douglas specification for the production function and a modified linear expenditure system, the paper presents an econometric model of household production, consumption and labor supply behaviour for a semi-commercial farm with a competitive labor market. The model, estimated from primary, cross-sectional, Malaysian data, is used to analyse the impact of migration, output price intervention and technological change on the agricultural sector. In doing so, the wage-rate is treated as an endogenous variable to be determined by the interaction of aggregate labor demand and supply curves obtained from the estimated micro functions.
