This paper investigates food waste at the consumer stage of the food chain. The authors conducted a questionnaire survey with 259 respondents to identify the key characteristics of food‐wasting consumers and to suggest strategies to improve food‐wasting behaviour. The results of the survey confirmed that the rate at which food is wasted depends on the age, economic status and education of the person managing food in a household, on the household's income per person and on total household income. Younger people, students, economically active people and people from higher‐income households (both per household and per person) waste more, while pensioners waste much less than other groups. However, the sex of the food manager is not associated with food waste. These demographic characteristics should be considered when designing consumer education campaigns focussed on changing consumer motivation and behaviour. This paper also recommends other solutions tailored for specific demographic groups: Younger people and students may be influenced by the actions of opinion leaders within social networks, and technical devices enabling better food management could help them reduce waste. Supporting work‐life balance, broadening the network of food delivery services and implementing corporate initiatives that support food waste prevention could help economically active people reduce their food waste. Additionally, offers of ready‐to‐eat food should be expanded for people with higher incomes.  相似文献

The aim of this study is to analyse how the internal market orientation, considered from a dual perspective, cultural and behavioural, affects the development of external market-oriented behaviours by improving the attitudinal results (affective commitment and job satisfaction) of the internal customers. An empirical study was carried out, based on the perceptions of 68 managers and 296 supervisors at four- and five-star hotels in Gran Canaria (Canary Islands, Spain). The findings show that (1) the internal market orientation (IMO) has a positive influence on the effective development of market orientation behaviours in managers and supervisors; (2) the IMO has a positive influence on the affective commitment and job satisfaction of hotel managers, but not supervisors; and (3) greater affective commitment and job satisfaction have no significant effect on market orientation behaviours in hotel managers or in supervisors. Based on the study results, the paper concludes with a discussion and implications for practitioners.  相似文献

This paper provides empirical evidence that combinations of option implied and time series volatility forecasts that are conditional on current information are statistically superior to individual models, unconditional combinations, and hybrid forecasts. Superior forecasting performance is achieved by both, taking into account the conditional expected performance of each model given current information, and combining individual forecasts. The method used in this paper to produce conditional combinations extends the application of conditional predictive ability tests to select forecast combinations. The application is for volatility forecasts of the Mexican peso–US dollar exchange rate, where realized volatility calculated using intraday data is used as a proxy for the (latent) daily volatility.  相似文献

We examine whether there is contagion from the US stock market to six Central and Eastern European stock markets. We use a novel measure of contagion that examines whether volatility shocks in the US stock market coupled with negative returns are followed by higher co-exceedance between US and emerging stock markets. Using our approach and controlling for a set of market-related variables, we show that during the period from 1998 to 2014, financial contagion occurred, that is, unexpected negative events in the US market are followed by higher co-exceedance between US and Central and Eastern European stock markets. Even though contagion is stronger during the financial crisis, it also occurs in tranquil times.  相似文献

Those responsible for making decisions in hospitals are increasingly aware of the need to efficiently manage hospital systems. An option for analysis is done by queuing models. In this paper is analyzed the service area ER, in a public hospital applying the concepts and relationships of waiting lines. From the model results, it is concluded that in the emergency department does not have the required minimum number of doctors to allow a steady flow of patients. With the model, the minimum required number of doctors is calculated to meet current and future demand for service with the same service time and the same discipline of service. Analytical models, allowing direct understand the relationships between service demand, number of doctors and patient care priority viewed as a queuing system. The work is useful for administrators and managers of hospital systems.  相似文献

This study empirically investigates the drivers of inflation in Ethiopia using monthly data over the period July 1998 to September 2020. It explores short-run and long-run effects of domestic and external determinants of inflation—including demand-side, supply-side, and structural factors—using the cointegration and vector error-correction methodology. Four measures of inflation are considered: cereals, food, nonfood, and all-items Consummer Price Index (CPI) inflation. A key contribution to the existing literature is the investigation of the role of the fiscal sector in modeling inflation, a topic that has been neglected in the existing studies on inflation in Ethiopia. The empirical results show that disequilibria in the monetary sector, grains sector, and food markets have long-run effects on inflation. In the short run, inflation is driven by structural factors (notably, cereal output gaps and imported inflation) as well as demand-side factors (notably, money growth and public sector borrowing). The results hold when analysis is limited to the high growth period from 2005 onward, following the end of the International Monetary Fund (IMF) program in the country. The evidence provides valuable insights in the context of ongoing macroeconomic policy reforms in Ethiopia.  相似文献

Summary. By generalizing the classical Knaster-Kuratowski-Mazurkiewicz Theorem, we obtain a result that provides sufficient conditions to ensure the non-emptiness of several kinds of choice functions. This result generalizes well-known results on the existence of maximal elements for binary relations (Bergstrom [4]; Walker [16]; Tian [15]), on the non-emptiness of non-binary choice functions (Nehring [12]; Llinares and Sánchez [9]) and on the non-emptiness of some classical solutions for tournaments (top cycle and uncovered set) on non-finite sets.

This paper uses data from the 2000–08 waves of the German Socio‐Economic Panel dataset (SOEP) to assess the impact of deprivation in various life domains upon individual well‐being. Unobserved heterogeneity is controlled for by means of a random effects model extended to include a Mundlak term and explicit controls for the respondents' personality traits. The paper shows that people care about social comparison information in a number of domains, not just income. Using an equivalent income approach, the estimates suggest that a one standard deviation deterioration of the individual position in the income distribution is as important as a 33.5 percent decrease in own income. This monetary equivalent amounts to an income variation of between 25 and 43 percent when it comes to other deprivation domains, including durables, accommodation, health, and social relations. These results recommend that in the fight against deprivation more emphasis should be directed to these non‐monetary relevant dimensions.  相似文献

We report on a simple experimental study designed to investigate the different gender attitudes towards socially responsible consumption. We use the Vote-with-the-Wallet Game, (VWG), a version of a repeated multiplayer prisoner’s dilemma that mimics the characteristics of the choice between a conventional and a socially responsible product. More precisely we test the effect of three factors: two different frames and an ex-post redistribution mechanism that transfers resources from purely self-interested consumers to responsible ones. We find that women remain significantly more cooperative (choosing more often the responsible good) when the redistribution mechanism is interrupted and are significantly less satisfied about the behaviour of the other players in that treatment.  相似文献
