Consider a firm as an organization that needs to efficiently coordinate several specialized departments in an uncertain environment.
Decision making involves collective planning sessions and decentralized operational processes. In this setting this paper
explores the role of economic modeling through an experimental game. Results support the idea that economic modeling favors
higher performance. Economic modeling facilitates the emergence of common knowledge and the decomposition of a group decision
problem into individual decision problems that are meaningfully interrelated.

The Value of Safety as Revealed in the Swedish Car Market: An Application of the Hedonic Pricing Approach 总被引:1,自引:0,他引:1
In this article the hedonic regression technique is used to estimate the value of traffic safety, using information from the Swedish market for automobiles. The results from the study show that the market price of an automobile is negatively correlated with its inherent risk level, i.e. Swedish car consumers pay a safety premium for safer cars. In comparison to previous Swedish stated-preference studies, this study reveals a lower willingness to pay for additional car safety, which might be a result of the interaction between government interventions and individual self-insurance and self-protection.JEL Classification: C51, D61, J28 相似文献

This paper introduces a new concept of left-side strong increases in risk (L-SIR) that extends the definition of strong increases in risk (SIR). We also provide somewhat stronger restrictive set of risk-averse decision-makers with a non-negative third derivative utility (prudence) to obtain an appealing comparative statics result for L-SIR.The authors gratefully acknowledge the helpful comments and suggestions of an anonymous referee 相似文献

Life style research and various disciplines dealing with regional studies argue that life styles are explanatory relevant for decisions in different behavioral areas, in particular for residential choices. However, the results of previous research are rather mixed. To specify the conditions for the explanatory relevance of life style based preferences for locational choices, this article ties in with a parsimonious decision theoretic model, which has been applied both in the sociology of the city and in life style research. Based on this theoretical framework an empirical study is presented, which tests the explanatory relevance of life styles for residential choices. The study is based on neighborhood survey data from Leipzig, representing a context, in which a strong impact of life styles may be expected. However, even in this context the empirical study shows rather limited explanatory power of life style based preferences for residential choices, whereas household arrangements and economic resource endowments of persons show much more explanatory power. 相似文献

One of the major aims of one-dimensional extreme-value theory is to estimate quantiles outside the sample or at the boundary of the sample. The underlying idea of any method to do this is to estimate a quantile well inside the sample but near the boundary and then to shift it somehow to the right place. The choice of this “anchor quantile” plays a major role in the accuracy of the method. We present a bootstrap method to achieve the optimal choice of sample fraction in the estimation of either high quantile or endpoint estimation which extends earlier results by Hall and Weissman (1997) in the case of high quantile estimation. We give detailed results for the estimators used by Dekkers et al. (1989). An alternative way of attacking problems like this one is given in a paper by Drees and Kaufmann (1998). 相似文献

Since the Software Engineering Institute has published the Capability Maturity Model in 1991, maturity models evolved into a commonly used instrument for assessing the state of a specific class of objects and for identifying improvement measures. As process improvement is a core task of business process management and takes top positions on CIO agendas, maturity models are prospering in this domain as well. However, it remains unclear which maturity levels should be aspired for distinct processes or process groups. Numerous companies strive for increasing or even maximizing maturity levels. Some maturity model specifications contain oppositional advice, but lack concrete recommendations. Even academia provides no answers. Against this background, we propose a mathematical optimization model that builds on insights from value-based management in order to analyze general economic relationships of process improvement with maturity models. The guiding effects of these relationships are illustrated using the example of ??CMMI for Services??. We conclude by discussing limitations and by pointing out theoretical as well as managerial implications. 相似文献

文献属于文化的范畴.由于物质载体的不同,文献也表现不同的文化理念.网络文献的出现,是社会网络化发展的结果.它具有时空性、创造性与科技性的特征,由此所反映出来的文化也具备了这些特点,本文分析阐述了两者之间的必然联系. 相似文献
