This article uses a survey of insurance agents in Florida to examine the manner in which insurance agents use and view the Internet as a method of marketing insurance products. The results of the survey suggest that the agents’ use of the Web and their attitudes toward the Web do not vary by demographic characteristics (including age, education level, gender, and income). In addition, the agents’ perception of the Internet as a threat (rather than an opportunity) does not vary by age or education level and is not correlated with their attitudes toward the use of the Web. However, while Internet marketing and other means of direct selling are viewed by the agents as equal threats to their sales, the agents believe that such marketing by other companies is a greater threat than that done by the companies they represent.  相似文献

Modeling Conditional Yield Densities   总被引:2,自引:0,他引:2  
Given the increasing interest in agricultural risk, many have sought improved methods to characterize conditional crop-yield densities. While most have postulated the Beta as a flexible alternative to the Normal, others have chosen nonparametric methods. Unfortunately, yield data tends not to be sufficiently abundant to invalidate many reasonable parametric models. This is problematic because conclusions from economic analyses, which require estimated conditional yield densities, tend not to be invariant to the modeling assumption. We propose a semiparametric estimator that, because of its theoretical properties and our simulation results, enables one to empirically proceed with a higher degree of confidence.  相似文献

This paper examines the debate about whether early entrants/pioneers to an industry enjoy long–term advantage over their successors. While most of the research suggests that pioneers are advantaged, there are methodological problems with these studies that tend to enhance the likelihood that pioneers will be found to be more successful. Through a case study of the US animation industry, it is shown that being a late entrant was almost certainly advantageous to some of the companies concerned. The paper explores the reasons why some late entrants prevailed over others and some of the mechanisms that allowed late entrants to overcome pioneers. The factors involved in survival relative to pioneers include the limited protection of patents, complacency, the mobility of staff with expertise in a new technology (in this case cel animation), and the neglected importance of managerial and organizational factors. It is shown that the findings also have implications for the population ecology approach.  相似文献

Practice rights legislation in Canada continues to be contested 50 years after its first enactment. In Ontario, one of the earliest provinces to enact restrictive legislation, the challenges have focused on how the legislation has been implemented rather than on whether or not public accounting should be regulated. To better understand the contested issues in this field, we examine the process undertaken by the Public Accountants Council of Ontario to implement the Public Accountancy Act of 1950. Our analysis is based on the first 15 years of the minutes of the meetings of the Public Accountants Council for Ontario, augmented by other archival sources such as court cases, newspaper clippings, correspondence and reports. Our intent is to document the process and “logic of appropriateness” used by the Council to construct its identity and stake out its “regulatory space” in the face of the ambiguity of the law and pressure from interest groups. We also identify the contradictions that were institutionalized in this field resulting in repeated challenges to the Council. We conclude by relating the historical insights from this analysis to the continuing challenges to practice rights legislation in Ontario.  相似文献

Currently, entrepreneurs and corporations overwhelmingly do not view the alleviation of global poverty as a strategic priority. Yet business activity can have a negative as well as a positive effect on each distinctive form of poverty. In order to reduce poverty, entrepreneurs have to find ways of limiting the negative aspects. This might be achieved by deliberately augmenting strategies so that they can achieve a synthesis, in partnership with governments and NGO’s. Alan E. Singer is a reader in strategy at the university of Canterbury. He was the 2004/5 Aram chair of Business Ethics at Gonzaga. He is author of Strategy as Rationality (Avebury), Co editor (with Pat Werhane) of Business Ethics in Theory and Practice (Kluwer) and editor of Business Ethics and Strategy (Ashgate, forthcoming). He has written journal articles on many aspects of strategy and decision making and has served on the editorial boards of Journal of Business Ethics (to 2003), Human Systems Management, Journal of International Entrepreneurship, African Journal of Business Ethics and the Journal of Economic Development and Business Policy.  相似文献

This paper examines the competitive characteristics of U.S. manufacturers in the machine tool (MT) industry. After several decades of decline, this industry has recently shown signs of a modest but sustained recovery. Empirical evidence from a national survey of 104 MT producers suggests that the revival of this sector has been driven by a combination of factors, including renewed export involvement, improved customer support, and better product design. Although most MT companies are small-to-medium-sized enterprises (SMEs), the survey data show that very small SMEs are poorly represented in the recovery thrust of the industry as a whole. Our principal conclusion is that the MT industry has been following an export-led path toward stabilization, but that certain types of small producers are unlikely to thrive for very long. The most serious problems facing small producers include shrinking local markets, import competition, shortages of skilled labor, and cyclical demand.  相似文献

Conclusion The investigation provides overwhelming evidence that decomposition tends to become increasingly more efficient than direct solution as the number of subproblems becomes greater.Further investigation would be required to obtain a comparable picture of the behaviour of decomposition with respect to an increasing number of variables in the master problem as their range of variation in the present study is rather restricted.It is gratefully acknowledged: that in implementing the decompositional procedure on the computer I have benefitted from Mr. A. C. McKay's advice on matters relating to the computer programmes; also that I enjoyed the pleasant and friendly co-operation of the staff of the computer Centre, University of Birmingham, without which the difficulties involved in carrying out the present task would have been compounded manifold; that Dr. C.-L. Sandblom carefully studied this paper and suggested a number of valuable improvements. Finally, I should like to thank Professor Kronsjö for the encouragement that he has given to me in executing this project and to the research council which made this investigation possible.  相似文献

A curtailed test for the shape parameter of the Weibull distribution   总被引:1,自引:0,他引:1  
Summary A procedure is proposed in this paper for testing the shape parameter, of the Weibull distribution. The test statistic which is based on the extremal quotient, possesses a monotone property which makes it possible for rejection earlier than the last planned observation of the null hypothesis,H 0: =0 when the alternative hypothesis isH a: <0 and early acceptance ofH 0 whenH a: >0. The test being scale-free, does not require the scale parameter to be known.  相似文献

Observations of nineteen hospitals show how organizational ideologies are manifested and sustained by beliefs, stories, languages, and ceremonial acts. The data indicate that harmonious ideologies accompany simple structures, but that discordant ones accompany elaborate structures. Through their effects on people and structures, ideologies guide organizations’responses to external threats.  相似文献

This paper argues that heterogeneity of agents’ characteristics plays a fundamental role in the economy and should do so in economic models. Three aspects are considered. Firstly the notion that assuming heterogeneity was a solution to the problem posed by the results of Sonnenschein Mantel and Debreu is considered and it is suggested that the more pragmatic approach adopted by Hildenbrand is likely to be more productive. Next the role of adaptation and evolution which necessarily involve variety or heterogeneity is examined. It is suggested that heterogeneity will persist since agents will only slowly learn to adapt and that in the meantime the environment will change. Lastly the role of heterogeneity in financial markets is examined. It is suggested that heterogeneous and varying expectations may account for many of the stylised facts which do not seem to be consistent with the standard financial markets model.“Variety is the spice of life”  相似文献
