MEASURING THE STOCK OF CONSUMER DURABLES AND ITS IMPLICATIONS FOR EURO AREA SAVINGS RATIOS

The purpose of this article is to estimate the impact of capitalizing durable goods on the euro area household saving ratios and disposable incomes for the first time. The reason for this exercise is twofold. Firstly, it is generally accepted that individual households regard consumer durables as assets even though they are not treated as such in the System of National Accounts 1993 . Secondly, the issue is related to the definition of household saving ratios. For instance, the U.S. Federal Reserve Board publishes three household saving measures. The main difference between these saving ratios is that one is derived by treating expenditure on consumer durables as investments while the other two are compiled by considering them to be household final consumption expenditure. We find that the effect of capitalizing consumer durables on EA saving ratios is moderate. The impact is lower than it is in the U.S.     

Would information on consumer confidence have helped to predict UK household expenditure during the recent economic crisis?

The objective is to investigate whether access to data on consumer confidence would have aided forecasts of the growth of UK household consumption expenditure over the recent period of economic crisis. A disaggregated study is performed on the basis that consideration is given not only to household spending in total but also to expenditure on each of durable goods, semi-durable goods, nondurable goods and services. The empirical analysis demonstrates how modifications which are made to the harmonized indicator of the European Commission are able to enhance predictive accuracy. However, the benefit which is derived from consulting consumer survey data does not extend to an earlier interval over which the behaviour of consumer sentiment was far less volatile.     

财富不平等会抑制金融素养对家庭借贷行为的作用效果吗*——基于CHFS数据的经验分析

本文基于2013年中国家庭金融调查（CHFS）数据,选用工具变量法,考察了金融素养对城乡家庭借贷行为影响的差异性,并验证了财富不平等扩大会抑制金融素养对家庭借贷行为的影响。研究发现：（1）金融素养是影响家庭借贷行为的重要因素。户主金融素养水平的改善显著提高了家庭发生借贷的概率与家庭借贷规模。（2）金融素养对城乡家庭借贷行为的影响存在明显差异,金融素养的提高对信贷约束较为严重的农村家庭借贷行为的促进作用更大。（3）财富不平等对家庭借贷行为存在明显的抑制作用,财富不平等的扩大减少了家庭借贷需求,降低了家庭发生借贷的概率和家庭负债规模。（4）随着家庭财富不平等程度的扩大,金融素养对家庭借贷行为的促进作用受到抑制。基于以上结论,政府应该大力开展消费者金融素养教育,注重家庭收入分配合理性,从而推动我国消费金融市场的健康发展。     

ACCOUNTING FOR NONMARKET HOUSEHOLD PRODUCTION WITHIN A NATIONAL ACCOUNTS FRAMEWORK

The satellite accounts illustrated in this paper reflect the household's role as a producer and an investor in durables as well as a consumer by modifying the NIPA's to (1) incorporate the value of nonmarket (unpaid) household work into GDP; and (2) treat expenditures on consumer durables as investment and measure the value of the services those durables provide. Additionally, an Input–Output (I–O) model highlights the household's functions as a producer and investor in much greater detail for the year 1992 by incorporating a household industry for each time-use activity and by showing the inputs to and outputs from each household industry's production.     

A mean-variance approach to forecasting with the consumer confidence index

This article refines the way consumer confidence survey data are used in forecasting models. The refinement is easy to describe: it extends existing models by controlling for statistically significant changes in consumer confidence index values. The motivation behind this refinement is simply that not all changes in the confidence index are statistically significant, and mean index values alone provide a noisy signal. Using Michigan Index of Consumer Confidence from 1967 through 2013, we show that controlling for significant versus insignificant changes in the consumer confidence index materially enhances the explanatory power of household expenditure forecasting models.

ACCOUNTING FOR HOUSEHOLD PRODUCTION: A PROTOTYPE SATELLITE ACCOUNT USING THE AMERICAN TIME USE SURVEY

This paper presents a satellite account where households are treated as production units. It extends previous work that treats consumer durables as investment and that values nonmarket household production activities such as cooking, cleaning, and childcare. Services from consumer durables and government capital related to household production are also valued. In constructing the updated accounts, this paper incorporates new time use data from the American Time Use Survey (ATUS) and the harmonized time use data from the Multinational Time Use Study (MTUS). This paper also discusses and incorporates recommendations made by the U.S. National Academies panel on nonmarket accounts.     

Effects of Changes in Household Size,Consumer Taste & Preferences on Demand Pattern in India

Current research in applied demand analysis has been addressing the twin issues of degree of non-linearity or curvature of the Engel curves and the ability to capture price effects appropriately by the demand system. Further, in addition to income and prices, the role of demographic variables like household size, composition and dynamic aspects like consumer taste & preferences are also being ’ emphasized in recent literature. Continuous efforts are being made to modify the existing models and propose new ones to incorporate the above developments. The purpose of this study is to re-examine the usefulness of the popular linear expenditure system vis-à-vis the two other flexible models viz. Nasse expenditure system, a generalization of the linear expenditure system itself, and the almost ideal demand system in the above context for India.The empirical results indicate wide variation in marginal budget shares and demand elasticities across income groups, rural-urban sectors and alternative models. The household size and consumer taste & preferences are found to be statistically significant. The results confirm the earlier findings that there are significant changes in consumer tastes away from cereals and pulses in favor of other food and nonfood commodities. The results also show that flexible models, which are theoretically superior, gave unacceptable positive price responses for some commodities and violated second order conditions of utility maximization. It is found that some ad-hoc separability restrictions are needed, thereby limiting the flexibility of the model, to get negative own-price responses in these models. But, second order conditions are still violated. The tests of nested hypotheses also confirm the need for inclusion of household size, consumer taste, income group and rural-urban dummies along with their interaction variables in the demand system.

     

老龄化如何影响我国家庭消费支出——来自中国综合社会调查的证据

基于中国综合社会调查（CGSS)的数据，本文谨慎定义老龄家庭后实证检验了老龄化对我国家庭消费支出的影响。研究发现，老龄化将使家庭消费支出显著下降并对大多数消费分项支出产生较大负面影响，同时会大幅提升家庭医疗服务支出；收入是老龄化影响家庭消费的重要中间变量。基于城乡分类子样本研究发现，乡村家庭受老龄化冲击异常严重，乡村医疗服务供给存在较大缺口。基于分层的城镇子样本回归发现，老龄化对城镇家庭消费的冲击集中体现在较低分位家庭。     

经济转轨与城镇化进程中的居民消费行为特征——对1396户城镇家庭的实证分析

基于中国9个省1396户城镇家庭的面板数据,运用系统广义矩估计法对一个包括习惯形成和不确定性的欧拉方程进行估计以考察家庭消费是否跨时演进,研究结果表明,偏好的设定偏误是传统的生命周期——持久收入模型不能很好地诠释中国城镇家庭消费决策的一个原因,在解释消费决策的影响因素时假定偏好的跨时可分性会得出错误的结论,城镇居民消费偏好的跨时不可分性以及由收入和支出不确定性引发的预防性储蓄动机是导致居民消费倾向持续偏低的重要原因。     

Demand for household sanitation in India using NFHS-3 data

India has the highest number of people defecating in the open, and the Indian Government is trying to eradicate by constructing toilets for its citizens. This paper is about whether the government is likely to succeed in its cleanliness drive mission by a supply-side policy. We examine the household preference and other the factors leading to open defecation in India. We examine preference for having a toilet in the household over the preference of other household durable goods. Our results suggest toilets get a lower preference—ranked 12, out of 21 different types of consumer durables we investigate. The results also indicate a strong case for imparting education and public awareness, especially, among the female cohort. We find the odds of having toilets in a household with an educated woman (18 years of schooling) is 3.1 times more than a household with illiterate or preschool educated women. Among other factors households living in urban areas are 19 times more likely to have toilets in comparison with their rural counterparts.     

Pensions for Singles and Couples

Retirement policies often seek to set pensions at levels that enable single and married pensioners to have the same standard of living. The existing literature on consumer equivalence scales provides little assistance in reaching this policy objective, as the estimated scales are both imprecise and reliant upon strong and opaque assumptions. This paper proposes an alternative modeling strategy which has low data requirements and involves the use of detailed, but transparent, assumptions about the extent of joint consumption of particular commodities. These assumptions are embedded in an economic model of household consumption and combined with household expenditure data to calculate consumer equivalence scales. It is estimated that, in 2003–04, Australian couples of Age Pension age who owned their own home needed expenditures between 1.32 and 1.60 times that of a single person. These scales were lower than those used in the pension system.     

Household composition,Engel curves and welfare comparisons between households: A duality approach

This paper is about household composition effects in consumer theory. These are important for the specification and estimation of Engel curves and demand functions. The models examined here have important applications in the areas of the measurement of cost of living indices, the study of poverty and inequality and in certain aspects of social policy. The models are based on the approach of Barten (1964). Taste differences between households are parameterized in a way which has been called simple good augmenting or simple repackaging in the literature on quality change. In this theory, changes in household composition play an analogous role to price changes. ‘True household equivalent scales’ are developed which are analogous to true cost of living indices and permit welfare comparisons across households.     

Rethinking real-time electricity pricing

Most US consumers are charged a near-constant retail price for electricity, despite substantial hourly variation in the wholesale market price. This paper evaluates the first program to expose residential consumers to hourly real-time pricing (RTP). I find that enrolled households are statistically significantly price elastic and that consumers responded by conserving energy during peak hours, but remarkably did not increase average consumption during off-peak times. The program increased consumer surplus by $10 per household per year. While this is only one to two percent of electricity costs, it illustrates a potential additional benefit from investment in retail Smart Grid applications, including the advanced electricity meters required to observe a household’s hourly consumption.     

Network effects and the choice of mobile phone operator

This paper explores the role of network effects in the consumer’s choice of mobile phone operators in the UK. It contributes to the existing literature by taking a new approach to testing for direct network effects and by using individual-level data, which allows to analyse the impact that the immediate social network has on consumer choice in network markets. For our empirical analysis we use two sources of data: market-level data from the British telecommunications regulator OFCOM and micro-level data on consumers’ usage of mobile telephones from the survey, Home OnLine. We estimate two classes of models which illustrate the role of network effects. The first is an aggregate model of the comparative volume of on-net and off-net calls. This finds that the proportion of off-net calls falls as mobile operators charge a premium for off-net calls, but even in the absence of any price differential between on-net and off-net, there is still a form of pure network effect, where a disproportionate number of calls are on-net. The second is a model of the individual consumer’s choice of operator. This finds that individual choice shows considerable inertia, as expected, but is heavily influenced by the choices of others in the same household. There is some evidence that individual choice of operator is influenced by the total number of subscribers for each operator, but a much stronger effect is the operator choice of other household members.     

Owner-consumers and efficiency

If each household owns the same fraction of a firm as its share of consumption, shareholders unanimously want marginal-cost pricing. Otherwise, profits are overemphasised relative to consumer surplus.     

The Demand for Food Products: An Analysis of Interpurchase Times and Purchased Quantities

In this paper we study household purchase behaviour of storable food products. An inventory model is developed in which the household chooses an optimal stock level of the product. Storage of the product is costly, there is a fixed cost per purchase occasion, and the market price is sometimes discounted because of price promotions. We show that the optimal purchase policy is an s , S policy. The model is used to derive predictions on the correlations between interpurchase times and purchased quantities on the one hand, and prices on the other. These predictions are empirically verified using consumer panel data.     

Consumer Debt and the Measurement of Poverty and Inequality in the US∗

This paper argues that interest on consumer debt must be taken into account when measuring poverty and inequality. These interest payments cannot be used to support household living standards. This makes middle- and low-income households worse off. Recent increases in consumer debt means that this deterioration in living standards is not captured by conventional government statistics. Using the Survey of Consumer Finances, we make estimates of poverty and inequality that take into account rising interest payments on consumer debt and discuss some of the implications of these estimates.     

Optimal Redistribution with Productive Social Services

Publicly‐provided private goods are conventionally considered consumer goods. Departing from this perspective, we analyze the public provision of inputs that improve household productivity (e.g., education and childcare). In a two‐class economy with distorting taxation, public provision is always welfare improving with respect to pure taxation, given that the public input directly affects household productivity. Moreover, the case for public provision strengthens as households' heterogeneity in input demand fades out, contrary to consolidated results in the literature. The features of optimal provision schemes depend on the nature of publicly provided input, namely, if it substitutes household productive capacity or just helps households to exploit it.     

Self-service activities and formal or informal market services

Household can provide themselves with services in different ways. Generally a household can produce a service itself, or buy it on a formal or informal market. On an informal market services are sold at a price substantially lower than on a formal market, because of tax evasion by both consumer and producer. This article investigates the choices made by Dutch households with respect to three services: small home repairs, car repair and maintenance, and ladies' hairdressing. The analysis shows that the mode of provision of the services is influenced not only by financial considerations, but also by the ability of the household to engage in home production, skills for and attitudes towards home production and the availability of informal market services in the local area.
