In this paper, two instruments of access price regulation, cost-based and retail-minus, are compared with the full deregulation hypothesis. For this purpose, a model that considers an upstream monopolist firm that sells a vital input to an independent firm and to a subsidiary firm in the downstream market is developed. The main conclusion of the paper is that retail-minus regulation avoids foreclosure and leads to better results than cost-based regulation in terms of investment level and consumer surplus. Moreover, retail-minus regulation allows a higher consumer surplus than deregulation of access price as long as the regulator carefully defines the retail-minus instrument. 相似文献

This paper shows how relevant concepts in educational effectiveness can support public policy in order to improve the performance
of educational systems. Specifically, value-added indicators and the property of their stability over time is addressed with
reference to application to school/teacher improvement. Findings of a longitudinal study developed in Portugal concerning
primary education in mathematics are presented. Variance component models are fitted in order to obtain those indicators yearly
to class-school units. Results of this study reveal that value-added indicators can be a useful instrument for progressive
improvement in education, particularly in countries with high rates of student retention and evasion. The novelty of this
paper is to measure value added over a single year rather than all stage of schooling that refers to more than 1 year. 相似文献

Large corporations have been using derivative instruments as a tool to protect their indirect exposure, as FX risks. A sample with 47 non-financial Bovespa Listed Brazilian companies from 2004 and 2010 was used to test the hypothesis that use of derivatives as a risk management policy tool reduces companies' cost of capital. In contrast to other countries, results rejected this hypothesis, showing that in Brazil there is a positive relationship between using these tools and cost of capital. However, a more in-depth analysis based on the TACC model for a Brazilian company, this hypothesis was not rejected after the 2008 crisis. 相似文献

The aim of this paper is to propose an integrative framework for understanding the determinants of business strategies to reduce greenhouse gas emissions and the impact of these determinants on performance. The proposed structural equation model is based on a survey of 319 Canadian manufacturing firms. The study calls into question the traditionally positive relationship between a firm's environmental commitment and its economic motivations. However, the results also show a win–win relationship between the commitment to reduce greenhouse gas emissions and financial performance. This study contributes to the understanding of the motivations underlying the efforts manufacturers make to tackle climate change and their economic benefits.

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

In a multi-commodity framework with absence of wealth effects, we prove the existence of equilibrium for Cournot oligopoly, and that the concept is completely non-ambiguous. We also obtain a uniquely defined endogenous inverse demand function, depending only on the competitive sector. 相似文献
