The performance of service industries in Canada has been lower than that of good industries over the last four decades, with noticeable exceptions such as for railways and telecommunication carriers. Service industries were less economically (and technically) efficient in that they generated less output value (quantity) per hour worked (level and growth) or per combined unit of labour and capital (multifactor productivity growth) than good industries. The relative output price of services declined slightly over time compared with goods. At the disaggregated level, changing relative output prices were substantial and proved to be an important factor explaining the relative satisfactory economic performance of many service industries despite their low technical performance. Nevertheless, the output share of service industries increased over that period, sustained, mainly, by the growing recourse of all firms to outsourcing of services.  相似文献

The purpose of this article is to study the level of “in‐stock” customer service performance being offered in the catalog channel of distribution. The article provides benchmark information for the catalog industry. More importantly, the article serves as one test of the effectiveness of the modern supply chain, where the expectation is for near perfect orders. Customer service levels are studied by using an empirical observation methodology in which catalog retailer's in‐stock performance was measured. Comparisons are made across item type, season, retailer type, and days from catalog receipt. Overall, items were out‐of‐stock during 15.9% of all checkpoints, compared to an 11.8% stock‐out rate in an earlier study of bricks and mortar retailers.  相似文献

This paper explores an unusual community-supported agriculture pilot project in London, concentrating on the contribution of ICTs in its development and impact. The paper contextualises the project within wider waves of local food activism and reflects on the relevance of using ICTs to increase awareness and community participation in the production and consumption of locally-grown food. The results are also analysed in light of the author's parallel research on the use of ICT for agricultural development, or “e-agriculture”, in Kenya. The paper contributes to ongoing debates on ICTs and agricultural development, by highlighting community-building and the emergence of new voices and conversations as key roles played by ICTs, contributing to the development of more participatory, resilient and locally-centred food systems. The results of the pilot however also acknowledge the essential role played by activities in real life in building communal food growing practices, which can be enhanced but not substituted by online communities.  相似文献

Retail decentralization is associated with town centre decline and a concern for revitalization. Using the case of Llanelli, South Wales, the effects of a new food superstore on shopping behaviours and opinions are explored. Surveys in 1997, 1999 and 2001 reveal a dramatic change in patterns of food shopping, but no real change for purchases of clothing or DIY goods. Disadvantaged consumers, the carless and the elderly, were already heavily reliant on town centre shops before the opening of the new superstore and changes in their shopping patterns were no different from other shoppers. The 'social' vitality of the town centre increased, as did shoppers' satisfaction with town centre shopping, but major spin-off shopping or 'economic' vitality has not yet occurred.  相似文献

Assessment of the role of the individual service worker in encouraging customer organizational citizenship behaviors (customer OCBs) is the primary focus of this paper. The researchers investigate this topic empirically across three service contexts. Customer OCBs are voluntary, outside of the customer's required role for service delivery, which provide help and assistance and are conducive to effective organizational functioning. In this paper, commitment to the service worker is the strongest predictor of customer OCBs. Further, personal loyalty to the service worker serves as a partial mediator of the effects of perceived benevolence of the service worker and commitment to the service worker on customer OCBs. Finally, theoretical, managerial and future research implications are included.  相似文献

The positive impact of air transport liberalisation as suggested by economic theories and empirical studies has inspired many developing countries like Nigeria to liberalise some of its Air Service Agreements (ASAs). This paper seeks to examine the extent to which international air service liberalisation has impacted upon Nigeria ten years after it was introduced. The research developed a cross-sectional model with passenger traffic as the dependent variable, while macroeconomic factors (trade and GDP), historical links, distance and ASAs (a proxy for liberalisation) served as independent or predictor variables. The analysis revealed a set of ASA stages in the country's policy-making process (restricted Bilateral Air Service Agreement, Open Skies Agreement and Yamoussoukro Declaration). Further analysis showed that the predictor variables were all significant in explaining passenger demand. The model demonstrated that the liberalisation of market access to the Open Skies Agreement level could stimulate traffic growth by at least 65 percent. The findings can assist in guiding policy and industry stakeholders in future decisions relating to liberalisation and ASAs.  相似文献

This paper examines the antecedents of millennials' organic food purchasing. A conceptual framework, based on product characteristics, and consumers' concerns and consciousness, is proposed. Data collection was conducted through a survey in two culturally and socioeconomically distinct countries (Brazil vs. Spain) to increase the robustness and generalizability of the results. The results show that product characteristics and consumer concerns improve millennials’ health consciousness and increase their social consciousness, which, in turn, increase their willingness to pay a price premium and their purchase frequency of organic foods. The findings show that the proposed model has high validity, with only one significant difference between the two countries. Theoretical contributions and managerial implications are discussed.  相似文献
