In this article, a new methodology for obtaining a premium based on a broad class of conjugate prior distributions, assuming lognormal claims, is presented. The new class of prior distributions arise in a natural way, using the conditional specification technique introduced by Arnold, Castillo, and Sarabia (1998, 1999) . The new family of prior distributions is very flexible and contains, as particular cases, many other distributions proposed in the literature. Together with its flexibility, the main advantage of this distribution is that, due to its dependence on a large number of hyperparameters, it allows incorporating a wide amount of prior information. Several methods for hyperparameter elicitation are proposed. Finally, some examples with real and simulated data are given.  相似文献

Within the context of the transformation of capitalist society in the last third of the twentieth century–a decline in the relative importance of manufacturing both in terms of GDP and employment, changes in the conception of work as mental rather than manual and in the types of interaction between capital and labour - labour relations systems in the twenty-first century will be very different from those prevailing today.  相似文献

Twenty-one pastoralists in the West Darling region of New South Wales were interviewed to gain an understanding of the attitudes of managers in this high-risk pastoral area to uncertain prospects. It was found that pastoralists had no difficulty in specifying subjective probabilities but in modifying probabilistic information they were conservative relative to the 'correct' revision implied by Bayes' Theorem. All the surveyed pastoralists were non-indifferent to risk, as evidenced by their non-linear utility functions for gains and losses.  相似文献

We argue that business firms are faced with new and changing social demands, and that it will be advantageous to the firm to treat the social demands as strategic issues. However, responding to these social demands strategically requires the application of new managerial concepts and techniques. In this paper we extend conceptually the lead-lag methodology of Ackerman and Bauer (1976), developed to deal with the evolutionary nature of social demands. Then we describe the problems of measurement, uncertainty and lack of common units of measures that have to be overcome before the responses to the social demands can be included in the strategic planning and budget process.  相似文献

Benefit transfer is a method for estimating the value of environmental goods that involves the use of past information on identical or similar goods. This paper considers the extent to which benefit transfer can be based on prior distributions elicited from expert opinion. We propose two alternative methods to elicit the parameters of a prior distribution from experts on environmental valuation. An experiment is carried out on the value of National Parks in Spain. The results from the elicited distributions are compared with the information provided by onsite samples of visitors. The results indicate that individual experts made different predictions about the potential value of the policy areas that were diverse and unable to accurately predict the value for each policy site. However, the average across the elicited distributions approaches the estimated distribution with empirical data and accurately predicts the relative values for the two policy sites considered.  相似文献

This paper analyzes the effects of International Monetary Fund (IMF) arrangements on the timing of inflation stabilization programs. By providing financial support that may allow the reduction of inflation without incurring politically unacceptable economic costs, the IMF can hasten stabilization. But, since support can also reduce the costs of inflation, it may instead delay it. Empirical results obtained for 10 countries that suffered from chronic inflation fail to support the hypothesis that IMF financial assistance accelerates stabilization. Rather, they indicate that other factors have a greater impact on the timing of stabilizations: greater fragmentation of the political system delays stabilization, while a higher level of inflation hastens it.

Are democracy and success compatible in a business organization? In this work we show how Spain’s Mondragón Corporación Cooperativa (MCC) has made it possible. MCC can be considered a world leader in cooperativism. It is one of the few contemporary business organizations that can be viewed as a democracy, and it represents a unique experience in the use of democratic and participatory methods in management. MCC has developed its own Management Model based on its cooperative principles, on modern management practices and on the cutting edge experiences of the most advanced companies. In this work we analyze the key elements of MCC’s democratic management model, developed around aspects such as corporate culture, organizational structure or human resources. We also look at the case of Irizar, a component cooperative of MCC internationally known for its successful management model. Finally, we outline some practical implications of introducing democracy into organizations, drawn from the experiences of MCC and Irizar.  相似文献

This article is geared toward shedding some more light on what may be the next space race and its contours.Space flight is undoubtedly a human achievement of the second half of the 20th century, and probably the most audacious one of the past century. The space race started suddenly in the 1950s and has grown explosively during the following two decades, but decreased steadily after the 1970s. After the 1990s, however, we have seen a shy rebirth of space-related activities, when many other actors (states) entered the stage, adding up to the agonizing role of the two-actor piece that we have witnessed during the so-called Cold War.The opening years of the 21st century provided a more complex narrative for space exploration. At the start of the new millennium a new technosphere [1] emerged, dominated by what is used to be called as the Information and Communications Technologies (ICT), with the Internet playing the leading role among the bandwagon of technological novelties that appeared during the twilight of space activities. In despite of the fact that artificial satellites represent the very backbone of the global communications system, space activities seem to play a secondary role amidst the apparently accelerated rate of change concerning the technological systems of the present technosphere. But, as it is demonstrated in this paper, things are changing, and very probably a renewed space race will unfold in the coming decades.A question may be placed: what happened? Why the Earth stood still with regard to the race toward the cosmos? Answer: futurists, even prestigious ones like Herman Kahn and Arthur Clarke, did not consider the existence of socioeconomic long waves (Kondratieff waves, or K-waves for short) with their two decades long economic downturn, which has contributed to the deceleration of space-related activities.Analyzing the worldwide evolving scenario of space-related activities during the last eighty years under the framework of the succeeding K-waves and applying some technological forecasting tools, namely the logistic analysis, technological surveillance and intensive data mining, scrutinizing more than 7500 events occurred in the period 1930–2010 related with space activities, it is demonstrated that the space race like the one that we have witnessed until now is a natural growth process that has saturated at the dawn of this century. The same analysis demonstrates that a new growth process in this field might be nowadays under way with contours very different from that imagined by futurists and science fiction writers sixty years ago. Also the main trends in the usage of launching vehicles and satellites are framed and discussed in this paper.  相似文献
