The relationship between social and financial performance (CSP – FP) has been a main objective in the literature on business
management, as it would provide an economic justification for the social investment insofar as it contributes to the creation
of value. This relationship has been empirically tested by several authors though without using a theoretical model that sustains
this relationship. The aim of this article is to propose a theoretical model of the process of the creation of value from
the reputation generated by companies, integrating the factors that have been shown to be more relevant in this process from
previous research, in such a way that hypotheses are put forward regarding the existence of this relationship and the factors
that determine it. Finally, an empirical test is performed using the 100 most prestigious companies operating in Spain during
2004. 相似文献

Ordering univariate distributions by entropy and variance 总被引:1,自引:0,他引:1
This paper examines the role of variance and entropy in ordering distributions and random prospects. There is no universal relation between entropy and variance orderings of distributions. But we place their relationship in the context of a stronger ordering relation known as dispersion ordering. Further, some conditions are identified under which variance and entropy order similarly when continuous variables are transformed. We also analyze parametric changes which do not disturb the agreement between these rankings. The results are conveniently tabulated in terms of distribution parameters. 相似文献

The economic and political changes which are taking place in Europe affect interest rates. This paper develops a two-factor model for the term structure of interest rates specially designed to apply to EMU countries. In addition to the participant country's short-term interest rate, we include as a second factor a 'European' short-term interest rate. We assume that the 'European' rate follows a mean reverting process. The domestic interest rate also follows a mean reverting process, but its convergence is to a stochastic mean which is identified with the 'European' rate. Closed-form solutions for prices of zero coupon discount bonds and options on these bonds are provided. A special feature of the model is that both the domestic and the European interest rate risks are priced. We also discuss an empirical estimation focusing on the Spanish bond market. The 'European' rate is proxied by the ecu's interest rate. Through a comparison of the performance of our convergence model with a Vasicek model for the Spanish bond market, we show that our model provides a better fit both in-sample and out-of sample and that the difference in performance between the models is greater the longer the maturity of the bonds.

A regulated upstream monopolist provides an input to firms in a downstream market. If the monopolist enters the downstream market, a natural concern is that it will act so as to raise its downstream rivals' costs. An offsetting incentive is that a higher downstream price will reduce demand for the input, which reduces the monopolist's profit. Conditions under which one incentive dominates the other are derived. The monopolist may desire to lower its downstream rivals' costs rather than raise them. These findings suggest that regulatory policy towards such downstream entry should not focus exclusively on the ability to discriminate. 相似文献

This article examines the joint effects on business strategy of the Internet and globalization. It develops a framework for evaluating how the Internet affects the globalization potential of individual industries and the global strategies that companies should adopt. The impact of the Internet will not be uniform. Not only do its direct effects vary from one industry to another, but also it speeds up globalization at different rates in different industries. The article shows how to use the Internet to support five types of global strategy: market participation, products and services, activity location, marketing, and competitive moves. 相似文献

Summary. If only the strict part of social preference is required to be transitive then Independence of Irrelevant Alternatives implies
that there is a coalition containing all but one individual that cannot force x to be socially ranked above y for at least half of the pairs of alternatives (x,y).

The complete Incremental Cost Test for cross-subsidies can be difficult to apply to a multi-product enterprise because every
possible subset of products must be tested. However, this combinatorial problem can be avoided when the enterprise’s cost
function is sub-modular by identifying the smallest subset of products causing the maximum cross-subsidy. This subset contains
all of the products, and only those products, that are responsible for the cross-subsidies left by a stipulated set of prices.
In addition, the subset can often be identified with a simple and efficient Myopic Algorithm. The algorithm should be particularly
useful as a method for detecting cross-subsidies in regulated enterprises and networks because the cost functions for these
industries are typically sub-modular. 相似文献

We provide a preference foundation for decision under risk resulting in a model where probability weighting is linear as long as the corresponding probabilities are not extreme (i.e., 0 or 1). This way, most of the elegance and mathematical tractability of expected utility is maintained and also much of its normative foundation. Yet, the new model can accommodate the extreme sensitivity towards changes from 0 to almost impossible and from almost certain to 1 that has widely been documented in the experimental literature. The model can be viewed as “expected utility with the best and worst in mind” as suggested by Chateauneuf, Eichberger and Grant (Chateauneuf, Alain, Eichberger, Jürgen, Grant, Simon, 2007. Choice under uncertainty with the best and worst in mind: NEO-Additive capacities. Journal of Economic Theory 137, 538–567) or, following our preference foundation, interpreted as “expected utility with consistent optimism and pessimism”. 相似文献
