Social class: a multivariate analysis of its effect on expenditures for household services

Multivariate statistical techniques were used to explore two major conceptual issues in consumer behaviour research involving social class: (1) the importance of income, as compared to social class, in determining household behaviour, and (2) the effect of the status of wives on the behaviour of their households. A subsample of expenditure data, collected from 5,994 husband-wife families, as part of the 1973 Consumer Expenditure Survey, was used in the analysis. The dependent variable was expenditures for household services. The independent variables included total consumption expenditures (a proxy for income), the status of the wife, the status of the husband, family type, location, and characteristics of the dwelling. The results of an Ordinary Least Squares regression procedure demonstrated that total consumption expenditures were the most important variable in determining expenditures for household services. The size of the effect of the status of the wife was comparable to that of the status of the husband. In both cases, the effect was significant but small.     

Satisfaction with household production: the effect of time spent in household production by husbands and wives

The purpose of the study was to examine the relationship between the extent of household production and satisfaction with household production. Data were obtained from 400 married couples who responded to a postal questionnaire. The dependent variable was an index of satisfaction incorporating two aspects of household production, quality and quantity. Regression analysis indicated that of the three variables representing the extent of household production in the model — hours spent by each spouse in household production and an activity index to measure the number of household production activities — only husband's hours spent in household production demonstrated a significant, independent effect. Other significant variables included husband's hours of market work, household net worth, age of respondent and gender of respondent. Two significant interactions indicated that (i) the relationship between wife's hours of household production and satisfaction with household production differed according to the gender of the respondent, and (ii) the relationship of husband's hours of market work and satisfaction differed according to the age of the respondent.     

From production to sustainability: Considering the whole household

The recent focus on sustainability as guiding principle for economic activity has generated many, and often conflicting, definitions of sustainable economic development. Yet while the terminology may be new, the discussion is not. Rather it parallels the discussion about biases of economic measurement and valuation concepts which have led to the neglect of the domestic and subsistence contribution of female householdership relegated to the informal sector. This paper argues that the selective focus of economics on narrowly defined productive functions has led to the detrimental neglect of sustaining functions without which production itself would be impaired. Informed by feminist theory, three principles are identified which are essential to the conceptual framework of a sustainable production theory. They are: concretion rather than abstraction, connectedness rather than isolation, and diversity rather than homogeneity. Without deterring from the importance of gender (especially in economics), the discussion of these principles of a sustaining orientation of economics is viewed in a broader context of mind-sets. It is argued that to reframe the relationship between production and sustainability as compatible rather than adversarial requires a broadening of theory, inquiry, and methodology. The voices of women who have gone largely unheard in economics are essential in this refraining process.

Zusammenfassung Von der Produktion zur Nachhaltigkeit: Die Betrachtung des Haushalts als Ganzes. Die neuere Betonung der Nachhaltigkeit als Leitprinzip für ökonomisches Handeln hat zu vielen — manchmal uneinheitlichen — Definitionen der nachhaltigen wirtschaftlichen Entwicklung geführt. Neu ist bei dieser Diskussion nur die terminologische Seite, die inhaltliche ist es nicht. Vielmehr gleicht sie der Diskussion über unzulÄngliche Konzepte zur ökonomischen Messung und Bewertung, die zu einer VernachlÄssigung des dem informellen Sektor zugeordneten Unterhaltsbeitrages der überwiegend weiblichen haushÄlterischen TÄtigkeit geführt hat. Der vorliegende Beitrag will zeigen, da\ die einseitige Betonung eng definierter produktiver Funktionen durch das ökonomische Denken zu einer schÄdlichen VernachlÄssigung der Unterhaltsfunktionen geführt hat, ohne die die Produktion sehr beeintrÄchtigt wÄre. Ausgehend von feministischer Theorie werden drei Prinzipien identifiziert, die für eine Theorie nachhaltiger Produktion wichtig sind: Konkretisierung statt Abstraktion, Verbundenheit statt Isolation und Verschiedenheit statt Einheitlichkeit. Wenn Produktion und Nachhaltigkeit in neuer Sichtweise nicht mehr nur als gegensÄtzlich, sondern als miteinander vereinbar gesehen werden sollen, so ist dafür eine Ausweitung der Fragestellungen der Theorie und der Methodologie notwendig. Die Stimmen der in der ökonomik weitgehend ungehörten Frauen sind für diese neue Sichtweise sehr wichtig.

     

Adolescent evening meal practices and attitudes toward the maternal role in evening meal preparation

The purpose of this study was to determine whether maternal employment is related to adolescent evening meal practices and to examine the attitudes of adolescents regarding the mother's role in evening meal preparation. A questionnaire was administered to 1,180 high school students in a suburban area of North Texas. Results indicated that maternal employment affects adolescent evening meals in the number of meals (i) offered per week, (ii) fully prepared by mother, and (iii) eaten away from home. Adolescent participation in meal preparation was higher for the employed group. Attitudes are different between the sexes and those with employed and unemployed mothers.     

Assessing nutritional adequacy of Americans based on individual food intake patterns

The study assumes that different food patterns are the major attributes that contribute and affect the adequacy of an individual's diet and nutritional status. Analysis of dietary patterns provides a means for generalization of the diversity of diets among individuals. It also provides a basis for assessing the nutritional adequacy of such diets. The study uses individual food intake data obtained from the 1977–1978 USDA Nationwide Household Food Consumption Survey (NFCS) to classify individuals into groups of similar food consumption patterns. Nutritional profiles associated with each identified food pattern were evaluated to determine the nutritional adequacy of such diets. To analyse nutritional adequacy, the study identifies four major dietary patterns based on cluster analysis. The concepts of nutrient density and index of nutritional quality were then used to assess the adequacy of each food pattern and to identify groups of individuals that may be at risk for malnutrition and other health concerns. Furthermore, regression analyses were used to estimate the relationship between individuals' socioeconomic characteristics and selected nutrient density of their diets.     

Consumption levels of households based on expenditure and household production

The distribution of consumption is the relative ranking of households with regard to their consumption level. This article discusses the possibilities and some of the problems in measuring consumption levels by combining expenditure and household production into one total figure. The feasibility of our approach is illustrated by using data from the Dutch 1980 budget survey and the 1980 time use study. The findings show that this total figure differs more between households of different size than between households by stage of life cycle or by income level.     

Determinants and adequacy of food consumption of children in La Trinidad,the Philippines

In the Philippines, vitamin A and vitamin C deficiencies, particularly among children, is a pressing health problem. This article reports the results of a research project that aimed at gaining insight into the factors in the household context that influence food intake of children and the role these factors play in vitamin A and vitamin C deficiencies. The research was carried out in La Trinidad, an urban area in the Philippines, where sufficient nutritious foods proved to be available. The results show that household income has only a minor impact on nutritional status. The nutritional status of children seems to be primarily influenced by their food preferences and the level of parental control on their food intake.     

Changing risk perceptions and food-handling practices of Oregon household food preparers

Results of 1986 and 1995/6 statewide random surveys were compared to assess changes in the risk perceptions and food-handling practices of Oregon food preparers. The 1986 survey revealed that perishable foods (baked potatoes, hard-boiled eggs, sliced turkey and cream pie) were often held at room temperature for longer than 2–3 h. Those who perceived greater food safety risks were significantly less likely to report temperature abuse of cream pie (P < 0·02) and baked potatoes (P < 0·001). Respondents reported serving raw and/or rare animal products (fish, milk, hamburger and pork) in both surveys. More food preparers perceived that serving undercooked foods was a ‘high’ risk in 1995/6 than in 1986. More (88%) also perceived that serving raw hamburger was a ‘high’ risk in 1995/6 than in 1986 (52%), possibly because of media coverage linking under-cooked hamburgers to the E. coli 0157:H7 outbreak in the Pacific Northwest. Those who perceived a ‘high’ risk were less likely to serve raw fish (P < 0·038) and raw milk (P < 0·002). Significantly more females perceived raw milk to be a ‘high’ risk (P < 0·003). The risks of consuming both raw fish and raw milk were more likely to be underestimated, however. Food safety education is therefore needed to help food preparers to identify ‘high’ risk foods and to motivate them to minimize risks.     

人口结构对居民储蓄率的影响研究——基于柯布-道格拉斯生产函数的实证分析

本文选取1990-2019年国家统计局公布的数据,运用柯布-道格拉斯生产函数模型来反映居民储蓄率和常住人口城镇化率、少儿抚养比、老年抚养比之间的关系。最终发现:1990-2019年,在常住人口城镇化率呈现快速单调递增的前提下,少儿抚养比一直呈现下降的趋势,并最终稳定在一个较低的水平状态;老年抚养比则一直呈现较为缓慢的增长趋势;居民储蓄率呈现波动性上升的趋势,并最终稳定在一个较高水平区间呈现震荡上升的状态。基于此,本研究提出:需要积极转变人口思想——从人口数量转变到人口质量;需要注意到人口年龄结构和城镇化水平的变化对经济活动所造成的影响。     

Expected and reported division of responsibility of household tasks among older wives in two residential settings

Literature on sex roles encompasses numerous studies on the division of responsibility in late-life marriages. Some older wives report that they continue to assume responsibility for mos: household chores and they actually perform most tasks. Other wives claim that following retirement, husbands increase their participation within the household arena. However, the increase tends to be in the level of activity involvement rather than in assuming responsibility for new or non-traditional chores. The trend toward egalitarianism in later life, especially for happy couples, is documented by numerous studies. It appears that while role expectations are less gender-specific among older people, they tend to follow the patterns established during middle-age. However, the research is not conclusive. No analysis has compared different living environments of older couples. A sample (n = 244) or older wives (mean age 72 years) living in two different residential settings were questioned via a mailed survey about their responsibility and behaviours regarding 12 household tasks: cooking meals, washing dishes, doing yard work, washing clothes, maintaining the car, writing letters, scheduling family events, getting or earning money, cleaning house, shopping, undertaking household repairs and making family decisions. High scores suggest a non-traditional approach to sex-role tasks, while low scores suggest egalitarian relationships. The views that wives have of division of responsibility of household tasks is explored: who should take responsibility for tasks and who does the tasks? Variables previously found to influence sex-role beliefs are examined. In particular, relationships between sex roles and marital quality, length of marriage, family income, frequency of interaction with children, residential environment and health are presented.     

The influence of various factors on the main meal format served in New Zealand households

The traditional main meal served in New Zealand households has been based on that of the British, i.e. a meat-based main course that includes potatoes and other vegetables followed by a dessert. In recent years consumption figures for meat suggest that New Zealanders are making changes in their diets. This study investigates whether this change has involved a change for New Zealanders in the format of their meal. It also examines the factors that influence meal choices. It was found that cultural traditions are strongly associated with meal format and that the meal format varies most for those who hold strong ecological beliefs. This finding suggests that nutrition educators attempting to bring about changes in a population's diet should institute changes within accepted meal formats.

Determinants of advertising expenditures: aggregate and cross-media evidence

Advertising expenditures account for 1 per cent of developed country GDP, having grown at an average real rate of 5 per cent p.a. over the 1980s. Trends in New Zealand have been similar to trends overseas. Hence analysis of the determinants of advertising in New Zealand should assist understanding of the determinants of advertising expenditures in other developed countries. We discuss changes in NZ's advertising industry and use a multi-equation co-integration framework to model the determinants of NZ advertising expenditure, both in total and across different media. We find that expenditure on advertising in all media is strongly pro-cyclical, that the allocation of expenditures depends on circulation patterns, and that press and magazines are complementary media and are substitutes for TV advertising.

Capital adequacy and asset securitization: an assessment of the world's central banks

National banking systems around the world are subject to disruption through the failure of a single institution. To lessen this risk, regulations governing bank definition, capital adequacy, overdraft operations, and asset securitization are needed. This article reports on these four issues and concludes that (1) the definition of a bank varies widely between nations; (2) some central banks do not require that sufficient capital be maintained to attenuate the effect of internal or external shocks; (3) overdraft operations, where allowed, often result in a high degree of system risk; and (4) off-balance sheet financing operations may not be as risky as first was reported.     

The contribution of home economics teaching to nutrition knowledge and food choice among adolescents

The diets of two groups of adolescent schoolchildren living in Lothian were assessed. Children who studied Home Economics at Standard Grade were compared with those who did not. A short questionnaire and a dietary diary were used to establish nutrition knowledge and food choice over a period of 7 days, allowing comparisons to be drawn between students who study Home Economics and those who do not. Nutrition knowledge was better among those studying Home Economics. Eating patterns among those studying Home Economics followed more closely the recommended percentages of dietary energy derived from protein, fat and carbohydrate, but there was also considerable evidence that those studying Home Economics tended to eat less generally and to have lower intakes of micronutrients, such as calcium, iron and folic acid. Possible reasons for the differences in nutrition knowledge and eating habits are discussed, with some indicators for future work in this area.
