We offer a new algorithm for analyzing innovation timing games. Its main advantage over the traditional approach is that it applies to problems that had previously been intractable. We use the algorithm to examine two classical innovation problems. We find that the competition takes the form of a waiting game with a second-mover advantage either for any level of R&D costs (process innovation) or for high R&D costs (product innovation). Moreover, both models predict that the second-mover advantage is monotonically increasing in the costs of R&D. 相似文献

Two experiments examined the effects of iterated polling and feedback on prediction accuracy for volatile world events using the Delphi paradigm. In both experiments, participants predicted rapidly changing geopolitical events. The first experiment occurred during the litigation surrounding the Clinton/Lewinsky affair in 1998. Results indicated that feedback improved individual and group accuracy for predictions of whether an event would occur. These types of predictions derived from group consensus were approximately 90% accurate, which was significantly higher than the average individual participant's accuracy. Neither polling nor feedback had much effect on time course predictions. The second experiment occurred during the American military action against the Taliban regime in Afghanistan in 2001. In Experiment 2, participants were polled three times to determine if increasing the number of iterated polls would improve Delphi accuracy. The results showed that accuracy improved from the first to the second poll but not from the second to the third. The groups predicted whether these scenarios would occur with approximately 75% accuracy, which was significantly higher than the accuracy of any individual participant. Once again, the Delphi procedure did not enhance time course predictions in Experiment 2. 相似文献

Der Beitrag vermittelt einen grundlegenden überblick über die Bedeutung des Vertrauens im Rahmen der ?konomischen Theorie.
Zun?chst werden ausgew?hlte Ans?tze im Rahmen der betriebswirtschaftlichen Vertrauensforschung diskutiert. Um eine strukturierte
Analyse zu erm?glichen, erfolgt eine differenzierte Betrachtung hinsichtlich der neoklassisch und institutionen?konomisch
fundierten Perspektive einerseits sowie der sozio?konomischen Perspektive andererseits. Die Diskussion um den Stand der Forschung
wird abgerundet durch einen überblick über empirische Ergebnisse der ?konomischen Vertrauensliteratur. Um noch offene Fragen
im Rahmen der Forschung zu adressieren, werden im Anschluss die unterschiedlichen Objekte des Vertrauens analysiert, differenziert
nach personalen Vertrauen und Systemvertrauen. Zum Abschluss gilt es die Verhaltensrisiken herauszuarbeiten, die mit Vertrauensbeziehungen
einhergehen und die Grenzen des Vertrauens in Organisationen zu beleuchten. 相似文献

Abstract The present paper combines loss attitudes and linear utility by providing an axiomatic analysis of corresponding preferences
in a cumulative prospect theory (CPT) framework. In a sense we derive a two-sided variant of Yaari’s dual theory, i.e., nonlinear
probability weights in the presence of linear utility. The first important difference is that utility may have a kink at the
status quo, which allows for the exhibition of loss aversion. Also, we may have different probability weighting functions
for gains than for losses. We apply the model to both portfolio selection and insurance demand. Our results show that CPT
with linear utility has more realistic implications than the dual theory since it implies only a weakened variant of plunging.

Résumé By far the most pressing problbem facing Belarus is the radioactive contamination resulting from the accident at the Chernobyl nuclear power station and the on-going threat to the environment posed by the destroyed reactor and those blocks which continue to produce electricity. The country is clearly not in a position to cope with the repercussions of the disaster. Western aid is required here, particularly to provide medical care for the population, decontaminate polluted areas, provide reliable measuring equipment and to analyse the level of contamination in food supplies. Air pollution, although worrying in some cities, is not as dramatic as in most of the polluted industrial centres of Russia and the Ukraine. Water pollution, too, is less serious than in most of the successor states to the Soviet Union. A serious problem is, however, posed by salification of the water supply by the potash industry. Recently environmental charges were introduced with the aim of improving environmental protection. Yet given rapid inflation and the persistence of soft budget constraints for enterprises, such charges are unlikely to have so far provided a significant incentive to more ecologically sustainable production in Belarus. 相似文献
