We analyze the success of filtering as a solution to the spam problem when used alone or concurrently with sender pricing, receiver pricing, or both. We find that filtering alone may exacerbate the spam problem in terms of both the total number of spam message sent and the expected number of spam messages received, because it may cause the spammer to send multiple variants of his message to each customer in an attempt to evade the filter. Sender and receiver prices work as expected. The effectiveness of each instrument improves as the levels of other instruments are increased.  相似文献

Abstract

The present paper seeks to provide some new insights into the precise nature and the analytical foundations (or lack of them) of the familiar industry supply curve. We reconsider some fundamental phases of its historical evolution. Two different traditions are distinguished: one consists of the formalisations of Marshall's theory proposed by Barone and, later, by Pigou, Viner, Harrod and Robinson; the other consists of the models of Hicks and Allen, on the basis of ideas and criticism put forward by other London School of Economics scholars, like Kaldor and Robbins, in the mid-1930s. It is argued that the second tradition did not really remedy the weak aspects of the Marshallian theory of supply.  相似文献

The purpose of this paper is to examine the behaviour of small independent financial advisors (IFAs) in terms of their involvement in networks and open innovation. A mail survey of small IFAs was undertaken utilising previously validated scales to assess business performance in relation to networking and open innovation. Results indicate that IFAs involvement in networks and open innovation can assist business performance. The managerial implications are that IFAs and other financial services organisation sector firms may be able to achieve higher sales growth by participating in networks and engaging in open innovation. This paper provides an original empirical assessment of possible strategies to enhance sales growth in small financial service sector firms facing volatile market conditions.  相似文献

Abstract

The 2010 British election particularly focused on the party leaders’ images – a departure in fifty years of British elections. The principal contribution of the article is to illustrate how a combined approach to assessing leadership positioning using both the traditional survey and semiotic analysis can provide insights into what image attribute dimensions end up in the minds of members of the public (actual positioning) and on what image attribute dimensions party marketers are trying to position themselves (intended positioning). Using data from the 2010 British general elections, our findings indicate that the combined methodological approach would be particularly useful for brands that need repositioning, those whose image attribute positions change dramatically over time, and those who wish to target previously unresponsive target audience segments.  相似文献

While decentralization is on the forefront of the reform agenda of many developing countries, few studies have performed empirical analysis to provide a holistic picture of the important fiscal, efficiency, and equity issues. Specifically, decentralization nearly always involves fiscal and administrative decisions by both national and sub-national governments, as well as intricate intergovernmental relations. Here, two empirical models are presented for the Mexican primary and secondary education sector. The first analyzes the efficiency-equity trade-off implicit the Mexican Federal Government's educational fiscal transfers to states. Unlike most similar analyses, this model analyzes the distribution of outcomes not simply expenditures. The second model analyzes the relative productivity of separate expenditures by the Federal and state governments before Mexico's recent educational decentralization legislation. The findings show that before the decentralization, the Federal Government exhibited some concern for equity, but that in doing so also treated states unequally according to criteria that have little to do with either efficiency or equity. In addition, the results show that the Federal Government may indeed have been the more efficient provider of primary and secondary education, raising concern for the fiscal and administrative relationship set up by the decentralization legislation: the Federal Government will continue to pay, while the states have gained relative autonomy over expenditures.  相似文献

An assessment of opponents' reactions to strategic and functional area policy decisions is shown to require knowledge concerning opponents' beliefs about the firm's behavior. This study introduces a methodology for incorporating such conjectures into the business planning process. It presents an analytical measure for these conjectural variations and discusses several illustrations. Examples of the application of the framework are provided by the Japanese flat glass industry and the U.S. domestic coffee roasting industry. The use of a broad range of conjectural variations in competitor analysis is discussed, and implications for business strategy formulation are highlighted.  相似文献

ABSTRACT This study sets out to examine two explanations for why employees engage in organizational citizenship behaviour (OCB). The first explanation views OCB as a form of reciprocation where employees engage in OCB to reciprocate fair or good treatment from the organization. The second view is that employees engage in OCB because they define those behaviours as part of their job. The research methodology consisted of survey data from 387 hospital employees on their perceptions of procedural and interactional justice, mutual commitment, job breadth and OCB. The results suggest that procedural and interactional justice are positively associated with mutual commitment that in turn, is related directly to OCB and indirectly through expanding the boundaries of an individual's job. These findings suggest that together the reciprocation thesis and ‘it's my job’ argument complement each other and provide a more complete foundation for our understanding of OCB. The difference between the two perspectives lies in the process by which individuals respond; that is, role enlargement and role maintenance. Implications and directions for future research are discussed.  相似文献
