Abstract Consider a portfolio containing number of risk classes. Each class has its own demand function, which determines the number of insureds in this class as a function of the premium. The insurer determines the premiums based on the number of insureds in each class. The “market” reacts by updating the number of the policyholders, then the insurer updates the premium, and so on. We show that this process has an equilibrium point, and then we characterize this point. 相似文献

To address agility in public administration, we have developed a knowledge acquisition infrastructure for legal knowledge, based on an implementation‐oriented conceptualization of the legal system. Our objective is to reframe legal knowledge as a knowledge source in a design‐oriented task ontology, building on insights from the CommonKADS methodology for intelligent system design. The main result is to make case law and legal expert knowledge of critical incidents in organizations, two diagnostic knowledge sources underutilized in modern management and engineering, more accessible as a resource for design of agile organizational structures and intelligent systems.

The open innovation approach has been one of the most discussed topics in innovation management literature in the 2000s. Over the past few years, academic publications on open innovation have increased substantially. This paper attempts to summarize and review the state-of-the-art of empirical open innovation research and develop new opportunities for open innovation research in the future. In order to make the papers more comparable, a clear focus on large-scale quantitative-oriented studies was set. From a total of 282 documents, 30 studies were analyzed in detail along four key dimensions: Firstly, different methods of measuring open innovation adoption are compared. Then, the level of open innovation adoption is analyzed on a general basis. Thirdly, the level of adoption is compared at the level of the open innovation mode (inbound and outbound). Finally, the study results regarding the variables that influence open innovation adoption are compared and conclusions for future research directions are drawn. 相似文献

Organizations are using Group Support Systems (GSSs) to improve the quality of group meetings. Keypad‐based GSSs are a widely used form of this technology, yet there has been little research on their use and effects. This paper reports the findings of a survey of facilitators of a particular keypad GSS. Facilitators indicate that keypad technology improves the quality of meetings for a variety of tasks in a range of group settings and cultures. The findings are in general agreement with field studies of workstation‐based systems. 相似文献

This article presents new estimates for investment and new growth accounts for three socialist economies between 1950 and 1989. Government statistics reported distorted measures for both the rate and the trajectory of productivity growth in Czechoslovakia, Hungary, and Poland. Researchers have benefited from revised output data, but have continued to use official statistics on capital input, or estimated capital stock from official investment data. Investment levels and rates of capital accumulation were much lower than officially claimed and over‐reporting worsened over time. A setback in factor accumulation—both investment in equipment and labour input—contributed very significantly to the socialist growth failure of the 1980s. 相似文献

An easy method to construct efficient blocked mixture experiments in the presence of fixed and/or random blocks is presented. The method can be used when qualitative variables are involved in a mixture experiment as well. The resulting designs are
-optimal in the class of minimum support designs. It is illustrated that the minimum support designs are more efficient than orthogonally blocked mixture experiments presented in the literature and only slightly less efficient than -optimal designs. 相似文献

Consumerism and care management continue to make inroads as cost-containment strategies for employers, as well as for employees who have endured the steady rise in benefit cost-shifting. The latest statistics and trends point the way to a new era of personal responsibility in health benefits. The author describes how this trend has grown, and where it is leading. 相似文献

Social contractarians commonly take social contracts to be solely hypothetical and refrain from elaborating on the factors
that influence the feasibility of the formation of social contracts. In contrast, this paper aims at providing a discussion
of the conditions affecting the feasibility of social contracts. I argue that the more aligned the preferences of group members
for public goods are, the more the individuals share similar social norms, and the smaller the group is the more feasible
a genuine social contract becomes. I provide evidence in support of my contention from the medieval Hanseatic League. At the
Hanseatic Kontor in Novgorod, one of the four major trading posts of the Hanseatic League in cities outside of Germany, German merchants agreed
to live under the rule of a constitution that gave rise to a political authority for the Kontor society. 相似文献

We explore whether competitive outcomes arise in an experimental implementation of a market game, introduced by Shubik (1973) [21]. Market games obtain Pareto inferior (strict) Nash equilibria, in which some or possibly all markets are closed. We find that subjects do not coordinate on autarkic Nash equilibria, but favor more efficient Nash equilibria in which all markets are open. As the number of subjects participating in the market game increases, the Nash equilibrium they achieve approximates the associated competitive equilibrium of the underlying economy. Motivated by these findings, we provide a theoretical argument for why evolutionary forces can lead to competitive outcomes in market games. 相似文献
