A comparative study of water usage in metered and unmetered households

The purpose of this research was to investigate the water usage in metered and unmetered households. The work also examined consumer attitudes towards water usage, including the belief of the need to use water more efficiently and the motivation to do so. Data were obtained by a self-administered questionnaire from 89 households in the Trafford area of Greater Manchester in the winter of 1995/6. This has provided information on ownership levels and age of water-using domestic appliances and outdoor water-using equipment. Although the survey showed some consumer awareness of eco-labelling, actual knowledge was low in both metered and unmetered households. Those respondents who thought water metering did, or would, encourage greater water efficiency were generally aware of how savings could be achieved. Metered households showed a stronger belief in the benefits of water economy. Twenty households each monitored their water usage for 7 consecutive days. A second questionnaire, aimed at clarifying practices, was then completed. This has provided information on total domestic water usage and variations in the components of water demand. Although there was a wide range of values in both metered and unmetered households, the frequency of use of appliances and equipment and per capita consumption were found to be related to household size. This showed larger households benefiting from an economy of scale. Metered households in this survey had a mean water consumption of 124·19 L/person/day compared with 137·28 L/person/day in unmetered households.     

Weight status and weight dissatisfaction of college students enrolled in a basic nutrition course

It has been suggested that general dissatisfaction with body weight, or anorexia-like behaviour, may be higher in students majoring in home economics, specifically dietetics, than in students in non-food and nutrition majors. This observation may be problematic in a student's future personal life or professional practice. The purpose of this study was to document the prevalence of general dissatisfaction with body weight, compared with actual body weight, in a group of college students enrolled in an introductory nutrition course. The sample included 169 female and 41 male students. Mean body weight and body mass index were 110 ± 20·7% of ideal and 23·4 ± 4·4, respectively. Dissatisfaction with weight was reported by the majority of students, especially females (76·2%). A significant relationship was found between reported weight dissatisfaction and actual weight status for females (P < 0·001). Furthermore, more females in dietetics were dissatisfied with weight (83%) than females in other majors (75%) although the difference was not significant. These results suggest that, while weight dissatisfaction was not significantly higher in dietetic majors, the high incidence of dissatisfaction in all females is a concern. There are, therefore, potential implications for the educational strategies of home economics faculties regarding appropriate attitudes about weight status and food.     

Impacts of Time and Transportation Costs on Food Shopping

This research examines the effects of transportation and time costs on the market basket costs of shopping at more than one supermarket. A 95-item market basket was priced in sixteen supermarkets representing four grocery chains in four geographically separated areas of Columbus, Ohio. The lowest cost market basket for each area was calculated and the costs of transportation and time added to determine their effect upon achieving a lowest cost market basket by shopping several supermarkets. When market basket items only or market basket items plus transportation costs were considered, savings were realized by shopping four supermarkets in an area as opposed to one. The addition of time costs to the total market basket cost caused shopping at two supermarkets to result in the lowest cost market basket in 75% of the observed store combinations.     

Factors Determining Credit Worthiness of Low Income Consumers

The purpose of this study was to identify variables that can be used in granting credit to low income consumers. Credit behavior, as exemplified by loan repayment, was examined with respect to economic, demographic, and socioeconomic characteristics of borrowers from a credit union that had been established to serve low income people in Columbus, Ohio. Findings indicate that early warning signals—default and delinquency—are given by borrowers when a loan is going bad. Consumer education and financial counseling might help eliminate this problem.     

Monetary Policy Response to Oil Price Shocks

How should monetary authorities react to an oil price shock? This paper shows that in a noncompetitive economy, policies that perfectly stabilize prices entail large welfare costs, hence explaining the reluctance of policymakers to enforce them. The policy trade‐off is nontrivial because oil (energy) is an input to both production and consumption. As welfare‐maximizing policies are hard to implement and communicate, I derive a simple interest rate rule that depends only on observables but mimics the optimal plan in all dimensions. The optimal rule is hard on core inflation but accommodates oil price changes.     

Introduction to the Special Issue on Behavioral and Experimental Public Economics

The workshop of the Association for Public Economic Theory on behavioral and experimental public economics was held at Ecole Normale Supérieure de Lyon, Université de Lyon, from June 24 to June 26, 2008. Thirty papers were presented in addition to keynotes by Charlie Plott and John List. The focus of the workshop was to test theoretical models using experimental methods to increase our understanding of the efficiency of mechanisms supporting the provision of public goods, social cooperation, and voting systems. This special issue aims at showing how lively and diversified the ongoing experimental research in public economics has come to be. We highlight three topics in particular: the power of voting and legal enforcement systems, the efficiency of various institutions to support cooperation in social dilemma games, and auctions.     

Characteristics of Consumers of Unpasteurized Milk in the United States

Despite considerable scientific evidence about the health risks of drinking unpasteurized (raw) milk, advocates continue to lobby for the reduction of state regulatory restrictions on the sale of unpasteurized milk. Multivariate analyses were performed on 1998–1999, 2002–2003 and 2006–2007 FoodNet Population Survey data to determine characteristics of unpasteurized milk consumers. Across all years of the survey, 3.4% of respondents reported consuming unpasteurized milk at some point in the previous seven days. Our findings indicate that unpasteurized milk drinkers in the states covered by the analysis are more likely to be Hispanic, less educated and of lower income than non‐drinkers and they are more likely to report drinking unpasteurized juice .     

STOCHASTIC FRONTIER ANALYSIS OF SPECIALIST SURGEON CLINICS

Stochastic frontier analysis was used to estimate the technical efficiency of specialist surgeon practices based in Gauteng Province, South Africa. The analysis was conducted for both single and multiple output production functions, while efficiency was allowed to depend upon surgeon and practice characteristics. Multiple output models, due to an increase in the number of observations, can be more precisely estimated and, as there are multiple observations per surgeon, can be estimated with fixed effects. The results of the analyses suggest that efficiency averages around 50% for this sample and is convex in years of surgical experience. The benefit of multiple output analysis – improved precision – obtains, while surgeon‐level fixed effects alleviate some concerns related to unobserved heterogeneity.
