We study order theoretic and topological implications for impatience of weakly Paretian, representable orders on infinite utility streams. As a departure from the traditional literature, we do not make any continuity assumptions in proving the existence of impatient points. Impatience is robust in the sense that there are uncountably many impatient points. A general statement about genericity of impatience cannot be made for representable, weakly Paretian orders. This is shown by means of an example. If we assume a stronger sensitivity condition, then genericity obtains. 相似文献

Abstract It was the Swiss actuary Chr. Moser who, in lectures at Bern University at the turn of the century, gave the name “self-renewing aggregate” to what Vajda (1947) has called the “unstationary community” of lives, namely where deaths at any epoch are immediately replaced by an equivalent number of births. It was Moser too (1926) who coined the expression “steady state” for the stationary community in which the age distribution at any time follows the life table (King, 1887). With such a distinguished actuarial history, excellently summarized by Saxer (1958, Ch. IV), it behoves every actuary to know at least the definitions and modus operandi of today's so-called renewal (point), or recurrent event, processes. 相似文献

Arrow's (1951) Impossibility Theorem is the idea that, given several well-known assumptions, the social orderings of particular alternatives that are meant to reflect individuals' preferences must match the preferences of an arbitrary individual (the dictator). A social-choice rule other than dictatorship is impossible. Following from Fountain (2000), the author presents another graphical proof of the theorem that is intended to be more accessible to students and teachers of economics. The principal strength of this approach is that the patterns of agreements and conflicts over all possible combinations of two individuals' rankings of alternatives are transparent; appreciating these patterns is the key to intuitively understanding Arrow's theorem. A self-test for readers (or a classroom exercise for students) is included. 相似文献

A Generic Framework for Automated Multi-attribute Negotiation 总被引:1,自引:0,他引:1
Agents in a negotiation may have to negotiate multiple issues simultaneously. Automated multi-attribute negotiation provides
an important mechanism for distributed decision makers to reach agreements on multiple issues. Moreover, it also furnishes
the opportunity to reach “win–win” solutions. In this paper, we first provide a survey that synthesizes the research on multi-attribute
negotiation. We discuss the limitations of the existing research and conclude that three key issues need further study: incomplete
information, Pareto optimality, and tractability. We then present a generic framework for automated multi-attribute negotiation
with two new mechanisms that address the above issues. Finally, we discuss the challenges and directions for future work. 相似文献

We analyze a monopolist's incentive to innovate a new antibiotic which is connected to the same pool of antibiotic treatment efficacy as is another drug produced by a generic industry. We outline the differences of antibiotic use under market conditions and in the social optimum. A time- and state-dependent tax-subsidy mechanism is proposed to induce the monopolist and generic industry to exploit antibiotic efficacy optimally. 相似文献
