住户部门生产核算：范畴的界定与方法的设计

住户无偿服务生产核算作为住户生产核算体系的重要组成部分,日益受到国内外研究学者的重视。借鉴SNA2008相关理论和方法,结合我国住户无偿服务生产的基本国情,本文界定出住户无偿服务生产的核算范围,设计出用于住户无偿服务生产核算的产出法和投入法;鉴于住户时间因素在无偿服务生产中的重要性,本文从时间投入的视角对我国住户无偿服务生产差异进行了研究,并分别研究了收入水平、教育程度等五个因素对住户无偿服务生产差异的影响;采用主成分分析法,设计出引起住户无偿服务生产差异的家庭因子、人口因子和经济因子,丰富了我国现行住户生产核算体系的理论和方法。     

Consumer acceptability of yellow maize products in Zimbabwe

This study analyzes consumers’ awareness of and attitudes towards yellow maize products in Zimbabwe and suggests intervention strategies that will ensure increased production and consumption of the crop, which is rich in provitamin A to help prevent the incidence of vitamin A deficiency prevalent among vulnerable groups. Data from 360 randomly selected rural and urban households show that yellow maize is known to all but few are aware of its nutritional qualities or consume it. The main source of supply is imported food aid. Rich in oils, carotenoids and fructose, yellow maize easily undergoes chemical changes to produce unacceptable organoleptic properties (or bad taste) if poorly handled during importation. These two factors are responsible for it being perceived inferior to white maize by consumers. Quality assurance during importation can improve consumer confidence but a long-term strategy will be to vigorously promote domestic production of yellow maize varieties rich in high levels of β-carotene that meet the preferences of consumers. Drawing from a probit model regression analysis, nutritional education can potentially promote yellow maize consumption, especially if targeted at low income households. Domestic production and consumption of yellow maize will decrease vitamin A deficiency among vulnerable groups and improve food insecurity through reduced grain prices and increased incomes for farmers. These results draw attention to the need for policy makers in developing countries to review their agricultural policies to ensure that they do not undermine the local production and consumption of nutritionally valuable crops.     

Addressing shortcomings in the Household Responsibility System: Empirical analysis of the Two-Farmland System in Shandong Province

Despite apparent overwhelming benefits, implementation of the Household Responsibility System (HRS) in China contained a number of flaws. The Two-Farmland System (TFS), which originated in Pingdu City in Shandong Province, sought to address the twin problems of land fragmentation and economies of size. A stochastic frontier production function analysis that isolates the impacts of land allocation reforms suggests that the TFS increased efficiency by around 7%. This article highlights the need for empirical analysis to assess objectively the merits or otherwise of particular reforms.     

转型时期农户的经营投资行为-以长三角15村跟踪观察农户为例

本文利用1995—2004年长三角15村近千个农户家庭的跟踪调查数据,实证分析了样本农户的经营投资行为。研究发现,不论是对农业投资还是非农投资,投资机会的增加都会产生显著的影响;农户在经济上向城市工人的转型深化,使得农业投资和非农投资都显著减少,但特别的是,有地农户的农业投资没有降低;融资约束对农业投资的影响不大,但对非农投资构成了严重的阻碍;土地对于农业投资具有显著的正向影响;税费改革对两种投资的经济影响均不明显。     

An Analytical Framework for Joint vs Separate Decisions by Couples in Choice Experiments: The Case of Coastal Water Quality in Tobago

This paper offers an analytical framework for analyzing joint and separate decisions by couples in the context of choice experiments for nonmarket valuation. It reports results from an attribute-based stated preference study in which members of couples are asked to conduct a choice-experiment first individually and then jointly. The choice context was the selection of which beach to visit while on vacation in Tobago. Available alternatives differed in attributes related to coastal water and beach quality such as level of coastal development and fish abundance. Tests of preference equality are reported and structured so as to identify the intra-couple decision-making patterns under taste heterogeneity with both finite and continuous mixed logit. Results from the latter suggest that women’s preferences are found to be predominant in the joint choice-experiment. Results suggest caution in using individual choice rather than joint couple choice when valuing quality changes impacting on couple activities, such as water and beach quality in Tobago, and call for further research on the topic.     

Using inverted Engel curves to estimate material standards of living in a household

This article demonstrates how to estimate latent total consumption expenditure or material standard of living in households by inverting estimated Engel curves. While the conventional estimator, total purchase expenditure, is unbiased for latent total household consumption expenditure, it is not variance minimizing since it is an un-weighted sum. In two stages, this article derives a variance-minimizing, unbiased estimator by first estimating and inverting Engel curves; then combining the estimators from the inverted Engel curves. The employed latent variable method allows for utilization of non-expenditure relations. The suggested method may help improve the accuracy in studies of consumption inequality and tax evasion.      

CHILD LABOR AND SCHOOL ENROLLMENT IN RURAL INDIA: WHOSE EDUCATION MATTERS?

This paper empirically analyzes the determinants of child labor and school enrollment in rural Andhra Pradesh, India. A village fixed‐effect logit model for each child is estimated with the incidence of child labor or school enrollment as the dependent variable, in order to investigate individual and household characteristics associated with the incidence. Among the determinants, this paper focuses on whose education matters most in deciding the status of each child, an issue not previously investigated in the context of the joint family system. The regression results show that the education of the child's mother is more important in reducing child labor and in increasing school enrollment than that of the child's father, the household head, or the spouse of the head. The effect of the child's mother is similar on boys and girls while that of the child's father is more favorable on boys.     

我国城镇居民平均消费倾向与收入分配状况关系的实证研究

中国的有效需求不足现象近年来成为一个被普遍关注的问题,而居民消费需求不足更是成为关注的焦点。本文在前人研究的基础上,从标准的消费者预期效用最大化模型出发,推导出中国城镇居民的个体"短视"消费模型和总量消费模型;运用我国1985～2004年城镇居民消费、收入及其他相关数据,通过误差修正模型和对数线性模型分别对数据进行了计量分析,发现在我国现阶段,城镇居民收入分配差距的扩大引起了居民平均消费倾向的减小,且其长期影响尤为显著。在对计量结果进行分析的基础上,本文给出了若干政策建议。     

The asymmetric behavior of household consumption under the business cycle

In this study, we examine whether and to what extent the pattern of household consumption is asymmetrically sensitive to economic changes. We use a threshold model with error correction to characterize household consumption under the business cycle. Using data from the 1979–2014 Survey of Family Income and Expenditure in Taiwan, we find that household consumption has pro-cyclical characteristics during the business cycle. More importantly, household consumption responds asymmetrically to economic fluctuations such that changes in consumption tend to be larger during expansions than during downturns. Furthermore, the nature of this asymmetry differs across household income quantiles.
