By using a unique data set that contains detailed information about consumer payment choice and consumers’ attitudes toward each payment method, we estimate the effects of payment card rewards on consumer choice of payment methods. Our approach allows us to control for consumer heterogeneity. We find the effects of rewards to be statistically significant across five retail types. Our policy experiments suggest that for the sub-population who hold both credit and debit cards, removing rewards would increase their share of paper-based payment methods (i.e., cash and checks), measured in terms of in-store transactions, by no more than 4 percentage points.  相似文献

The beef production function of different enterprises has been estimated for the sample farms in Nova Scotia. The returns to scale and marginal productivity of resources are derived from the production functions. It indicates decreasing returns to scale and the low marginal productivities of grain, labor, and variable costs for all enterprises. Grain and hay are the most important feeds for beef production. Many beef farms in the province produce more roughage than grain. The marginal rate of substitution of hay for grain is diminishing. Beef farmers can produce equal amounts of product with different combinations of the two feeds. The results provide the possibility of finding the least-cost combination of inputs. This study has specified the optimum input levels under different prices of inputs. It will help beef farmers to allocate their resources properly in order to maximize profits. Les fonctions de production de boeuf de différentes entreprises ont été eslimées à partir de fermes selectionées en Nouvelle-Ecosse. Les économies ?échelle et la productivté marginale des ressources sont dérivées des fonctions de production. On retrouve dans toutes les entreprises des économies ?échelle décroissantes et une faille productivity marginale du grain, du travail et des couts variables. Le grain el le foin constituent la plus importanle source ?alimentation dans la production de boeuf. Plusieurs fermes ?élevage de boef produisent plus de fourrage que de grain. Le laux marginal de substitution du foin pour le grain va en diminuant. Les éleveurs de boeuf peuvent produire des quantités egales par des combinaisons différentes de ces deux aliments. Les résultats ptrmettent de déterminer la combinaison la moins coûteuse pour la consommation des aliments, Cette étude a détérmine les niveaux optime de consommation selon les différents prix des aliments. Elle aidera les producteurs de boeuf à distribuer adéquatement les aliments afin de maximiser les profits.  相似文献

This paper presents an intermodal network optimization model to examine the competitiveness of 36 alternative routings for freight moving from China to and beyond Indian Ocean. The proposed model, which is built upon the principles of goal programming, is able to handle multiple and conflicting objective functions such as minimizing transportation cost, transit time and transit time variability while ensuring flow continuity and transit nodes compatibility among the rail, road, ocean vessel, airplane and inland waterway transports. Transportation time and cost obtained from comprehensive industry sources are then fed into the intermodal transport network connecting two important Chinese origins and four Indian destinations, from which the most attractive routes are identified. In addition, the paper investigates several non-dominated transportation cases through sensitivity analysis tests, and analyzes the potential competitiveness and possible influences of future route developments to current transportation patterns in Asia.  相似文献

Abstract

This paper investigates the valuation of discrete dynamic fund protection (DFP) under Levy processes. Specifically, the analytical solution of discrete DFP under Lévy processes is obtained in terms of Fourier transforms. The derivation uses Spitzer’s formula and leads to a recursion on computing the characteristic function of the maximum protection-to-fund ratio using the Fourier inversion. DFP can then be valued efficiently and accurately via the fast Fourier transform. The pricing behavior of the discrete DFP is numerically examined using several Levy processes, such as geometric Brownian motion, jump-diffusion models, and variance gamma process. Numerical experiments confirm that the proposed approach produces highly accurate discrete DFP values within 1 second.  相似文献

This paper analyzes semi-parametrically the survival odds of de novo entrants in the liberalized intra-European scheduled passenger airline industry with respect to three sets of determinants: strategic positioning, inaugural market entry and network economics. Among these determinants, a ‘low-cost’ strategic position does not confer survival benefits to new entrants. Entering markets with different levels of prior concentrations – which economists traditionally relate to different pricing powers – does not significantly affect the survival odds of new entrants. Entering mid-sized markets adversely affects entrant survival, while entering large, small or new markets at inception does not noticeably impact entrant survival. Network economics that corresponds to low operating costs (aircraft size) is a consistent contributor to entrant survival. In addition, new entrants based in France or Ireland are less likely to survive than others, reflecting the strong negative impact of intermodal competition and a strong, entrenched entrant.  相似文献

People are becoming more health conscious nowadays, but most of them are not able to adopt a lifestyle with adequate physical exercise and a healthier eating pattern. Many attempt to compensate by taking ‘health foods’. Despite the recent economic recession, the functional food market is expanding rapidly in Asian countries. Recent statistics indicate a huge increase in weight loss and functional food product advertising expenditure in Hong Kong and other Asian countries. In a large scale survey conducted by the Hong Kong Consumer Council on advertisements, it was found that 85% of the medicines, health food and therapies sampled contain questionable claims and misleading messages, which was the second most problematic category of the survey. In addition, young people do not understand much about modern food processing, in particular with regard to low energy and functional foods, and they know very little about modern food marketing strategies. The situation is potentially detrimental to consumer welfare, especially to the younger generation. This study was conducted to reflect critically on implications of the issue on the health and well‐being of young people in Hong Kong. Attempts are made to explore directions for designing relevant and effective education programmes to empower young people's abilities in understanding food advertising strategies and making informed decisions on food choice. This paper begins with a critical review of the current situation with regard to Hong Kong. Then, the results of an interview survey and a questionnaire survey on pre‐service and in‐service teachers’ perception towards misleading food advertising and labelling are reported. The situations at schools are defined and problems faced by teachers in providing relevant consumer education programmes to students are identified. Finally, some prospective foci for further investigation of this important issue, with a view to developing students’ critical skills in evaluating claims offered in food advertisements, will be considered.  相似文献

The purpose of this article is to evaluate the impact that knowledge management has on new product success. In this study, two aspects of knowledge management—knowledge acquisition and knowledge dissemination—were examined relative to traditional determinant of new product success. Moderating effect of competitive intensity is also investigated. The results generally support the importance of knowledge management to new product success. These findings imply that if organizations fail to understand the subtle ways by which different features of KM influence new product success, they may fail to harvest the full value of KM.  相似文献

This paper seeks to understand the professionalisation project of accountants by historically 'following' the organised, contingent interests of state agencies, professional elites, business and community organisations. Drawing upon recent research on the accounting profession that is grounded in the work of Weber, Marx and Foucault, professions are seen as self-interested transnational collec-tives whose internal modes of membership control and external relationships with other organised interests are both structured and subject to continual renegotiation and change. This particular framing of professional associations is illustrated by documenting the emergence of the Australian Public Sector Accounting Standards Board in 1983.  相似文献

Although a general association between the role of international assignees and knowledge transfer has been noted in the international human resource literature, very little is known on how subsidiary knowledge flow strategies influence the purpose of expatriate assignments. Building specifically on Gupta and Govindarajan’s typology of subsidiary knowledge flow strategies and Hocking’s expatriate assignment purpose, we examine the link between subsidiary knowledge flow and the purpose of expatriate assignments using a mixed method approach. Combining survey data and qualitative interviews from 156 subsidiaries in the service and manufacturing sector in Malaysia and Singapore, we find that subsidiaries with divergent strategic roles have different knowledge flow strategies, thus leading to different purposes of expatriate assignments.  相似文献

This research sheds new light on how information technology (IT) assimilation affects exploratory and exploitative innovation in the context of small‐ and medium‐sized firms (SMEs). This contextualization is important in establishing the boundary conditions for the theory, as well as generating specific managerial insights for SME managers. A sample of 248 U.K.‐based SMEs in the manufacturing industry demonstrates contextual ambidexterity (CA) mediates the relationship between IT assimilation and two types of innovation. This finding highlights that IT assimilation does not automatically promote innovation. Instead, IT assimilation represents a critical resource that enables the effective implementation of CA, which in turn affects innovation. This implies that SMEs cannot fully realize the potential of their IT assimilation and use it to enable innovation without implementing CA. Furthermore, this study differentiates between two different dimensions of knowledge base: knowledge breadth and knowledge depth. This study finds that knowledge breadth moderates the indirect IT assimilation–exploratory innovation relationship by influencing the effect of CA on exploratory innovation. Knowledge depth, on the other hand, moderates the indirect IT assimilation–exploitative innovation relationship by influencing the effect of CA on exploitative innovation. This finding implies that SMEs can benefit from their IT assimilation that enables them to engage in CA, which in turn allows them to perform innovation. However, it is apparent that the dimension of knowledge that SMEs hold internally can determine what types of innovation that they are able to perform.  相似文献
