Selection Tournaments, Sabotage, and Participation   总被引:2,自引:1,他引:1  
This paper studies sabotage in tournaments with at least three contestants, where the contestants know each other well. Every contestant has an incentive to direct sabotage specifically against his most dangerous rival. In equilibrium, contestants who choose a higher productive effort are sabotaged more heavily. This might explain findings from psychology, where victims of mobbing are sometimes found to be overachieving. Moreover, sabotage equalizes promotion chances. The effect is most pronounced if the production functions are linear in sabotage, and the cost functions depend only on the sum of all sabotage activities: in an interior equilibrium, who will win is a matter of chance, even when contestants differ a great deal in their abilities. This, in turn, has adverse consequences for who might want to participate in a tournament. Because better contestants anticipate that they will be sabotaged more strongly, it may happen that the most able stay out and the tournament selects one of the less able with probability one. I also study the case where some contestants are easy victims, that is, easier to sabotage than others.  相似文献

This study is based on the case of BMW, and aims to improve the determination of perceived consumer satisfaction in the automotive industry by transferring existing knowledge from the health care sector. A literature analysis of the health care sector and the automotive industry was conducted to identify the common concepts of determining satisfaction. These were the service encounter, situational factors, and sociodemographics. The practical application was tested by analyzing a contemporary survey from BMW. Based on the findings, managers responsible for customer satisfaction in after-sales services in the automotive industry could improve measurement of customer satisfaction.  相似文献

This study examines the impact of different degrees of organizational coupling among the members of innovation alliance project networks on the commercial performance of collaborative innovations. Specifically, we study how type of innovation (modular vs. architectural innovation) moderates this relationship. Using data from 664 product innovation networks from five different industries in the United States, we find that the degree of organizational coupling among innovation network members significantly affects the commercial performance of collaborative innovations and that the type of innovation has a significant moderating effect. More specifically, the impact on commercial innovation performance of organizational coupling is positive for modular innovations and negative for architectural innovations.  相似文献

Collusion has often been alleged in industries where long‐lived capacity investments are important. This article develops a computational duopoly model with capacity investments, demand shocks and either competitive or collusive pricing. It shows that allowing for endogenous capacity investments can sometimes make collusion less valuable than competition and that it can change the normal relationships between the profitability of collusion and both the discount rate and industry‐wide demand shocks.  相似文献

Although insurers over services, they are no advisers/consultants. Nevertheless, the jurisdiction has already established an pre-contractual insurers duty to l advise insureds under the validity of the old VVG according to general civil law rules. Article 6 VVG standardizes such duties for the first time and aims to guarantee customers proper advice/consultancy particularly before the contract ends to prevent lapses in coverage. Therewith some considerable questions referring to concurrent laws concerning the law of the general terms and conditions, which aim to guarantee reliable and transparent information for customers in a quite similar way, arise. The author discusses this problem of concurrent laws and develops criteria which show which law is applicable on what occasion. As a result, a possibly contradictory pre-contractual double review is avoided.  相似文献

This paper sheds light on some unexpected consequences of health insurance regulation that may pose a big challenge to insurers' risk management. Because mandated uniform contributions to health insurance trigger risk‐selection efforts, risk adjustment (RA) schemes become necessary. A good deal of research into the optimal RA formula has been performed. A recent proposal in Switzerland has been to add ‘Hospitalization exceeding three days during the previous year’ as an indicator of high risk. Applying the new formula to an individual Swiss health insurer, its payments into the RA scheme are predicted to increase substantially, reaching up to 13% of premium income. Its mistake had been to implement Managed Care successfully, resulting in low rates of hospitalization. The expected risk management response is to extend hospital stays beyond three days, contrary to stated policy objectives.  相似文献
