An alternative to traditional regulations of fisheries to avoid rent dissipation is the use of individual transferable quotas (ITQ
s
) where prices in the quota market provide the necessary information to owners of harvest rights to contract with each other. However, even under such a decentralized regime, information on the underlying technology of the fishing vessels is also necessary. First, since most fisheries consist of many interrelated production processes, in order to avoid rent dissipation by discarding wrong output mix etc., the structure of production in the multispecies fishery must be known to design a proper quota system. Second, an ITQ system may create incentives for misreporting by understating the actual catch. This may especially be the case where the expected degree of self-enforcement is low. The paper proposes a way to reduce the information requirements under regulation with asymmetric information by constructing a typical firm and comparing performance for the other vessels to this firm. Based on the typical firm, and if the industry is relatively homogenous, the performance and hence catch of any other firm in the industry can be predicted within a certain range. Further, the paper applies this idea to the Norwegian trawler fleet to assess the production structure in terms of jointness, input-output separability, and the supply and demand elasticities for the fishing firms. This information characterizes the fishery and thus how the quota system may be designed and how to construct a yardstick in order to reduce the enforcement cost under a decentralized regulation of ITQs.The authors would like to thank Trond Bjørndal, Røgnvaldur Hannesson, Ola Flaaten and two referees for useful comments and suggestions. 相似文献

We examine returns and ending wealth in portfolios selected from 1,000 large U.S. stocks over a 20‐year holding period. Shortfall risk, the possibility of ending wealth being below a target, is a useful metric for long horizon investors and is consistent with the Safety First criterion. Density functions obtained from simulations illustrate that shortfall risk reduction continues as portfolio size is increased, even above 100 stocks. A slightly lower risk can be achieved in small portfolios by diversifying across industries, but a greater reduction is obtained by simply increasing the number of stocks. 相似文献

Leaders and followers both associate authenticity with sincerity, honesty, and integrity. It's the real thing--the attribute that uniquely defines great managers. But while the expression of a genuine self is necessary for great leadership, the concept of authenticity is often misunderstood, not least by leaders themselves. They often assume that authenticity is an innate quality--that a person is either genuine or not. In fact, the authors say, authenticity is largely defined by what other people see in you and, as such, can to a great extent be controlled by you. In this article, the authors explore the qualities of authentic leadership. To illustrate their points, they recount the experiences of some of the authentic leaders they have known and studied, including the BBC's Greg Dyke, Nestlé's Peter Brabeck-Letmathe, and Marks & Spencer's Jean Tomlin. Establishing your authenticity as a leader is a two-part challenge. You have to consistently match your words and deeds; otherwise, followers will never accept you as authentic. But it is not enough just to practice what you preach. To get people to follow you, you also have to get them to relate to you. This means presenting different faces to different audiences--a requirement that many people find hard to square with authenticity. But authenticity is not the product of manipulation. It accurately reflects aspects of the leader's inner self, so it can't be an act. Authentic leaders seem to know which personality traits they should reveal to whom, and when. Highly attuned to their environments, authentic leaders rely on an intuition born of formative, sometimes harsh experiences to understand the expectations and concerns of the people they seek to influence. They retain their distinctiveness as individuals, yet they know how to win acceptance in strong corporate and social cultures and how to use elements of those cultures as a basis for radical change. 相似文献

We analyze the choice between the origin and destination principles of taxation when there is product differentiation and
Bertrand competition. If taxes are redistributed to consumers and demand is linear the origin principle dominates the destination
principle whatever the degree of product differentiation and extent of economic integration. With nonlinear demand the origin
principle dominates if there is sufficient economic integration. When the social value assigned to tax revenue is higher than
the private value, the destination principle dominates for intermediate values of product differentiation and economic integration.
The same results are also shown to hold with Cournot competition.

An Entrepreneurial System View of New Venture Creation 总被引:3,自引:0,他引:3
Heidi M. Neck G. Dale Meyer Boyd Cohen Andrew C. Corbett 《Journal of Small Business Management》2004,42(2):190-208
This paper reports the results of a two-phase study that explores new venture creation within the context of an entrepreneurial system. First, a genealogy of high-technology companies is presented depicting a high spin-off rate resulting from the presence of seven incubator organizations. Second, semantic structure analysis ( Spradley 1980 ) based on semi-structured interviews with founders is used to develop a taxonomy. This taxonomy depicts the relationship among components in one entrepreneurial system, Boulder County, Colorado, that encourages, supports, and enhances regional entrepreneurial activity. Findings indicate that incubator organizations, spin-offs, informal and formal networks, the physical infrastructure, and the culture of the region are related uniquely and interact to form a system conducive for dense high-technology entrepreneurial activity. Additionally, greater rates of new venture formation were found following critical moments in the life of incubator organizations. 相似文献

In a recent study Nelson and Granger (1979) reported on their experience with using the Box-Cox transformation to forecast twenty-one actual economic time series and four simulated series. The objective of this brief note is to offer some qualifications to the results of Nelson and Granger, and to offer a few alternative interpretations. 相似文献

Cost-benefit analysis is a popular method of evaluating both public and private investments. This paper explores the theoretical basis of cost-benefit analysis, the methodology of its application and the policy ramifications arising from its application in terms of public investments. The discussion presented in this paper is relevant to public investments undertaken at all levels of government. A main conclusion of this paper is that the social conscience of the planner or decision-maker and his knowledge of the benefits and shortcomings of cost-benefit analysis are key factors in successfully implementing public investments. 相似文献
