The notion of path dependence is regularly deployed to account for the way past commitments have an important bearing on current choices. We make a distinction between the notions of past and path dependence and focus on path dependence as two types of event sequences: selfreinforcing and reactive. We then address the issue of how the notion of path dependence can be reconciled with a temporal-relational perspective on agency. These notions are tested and refined using a longitudinal case study of ICI's move away from chlorofluorocarbons (CFCs) and the decision to build three plants to produce one CFC alternative (HFC-134a) for the global refrigeration market. The paper concludes with a discussion of the implications of path dependence for research on technological and firm evolution.  相似文献

The paper examines the contributions of Myrdal, Lindahl, Hicks and Hayek that initiated the transition from the traditional long-period method to the methods of 'intertemporal' and 'temporary equilibria' in neoclassical general equilibrium analyses. It is shown that in the early contributions the idea of a tendency towards a long-period position was not completely abandoned, and that the new 'dynamic' equilibrium concepts were conceived by some of their originators as useful analytical devices for studying transitions between long-period equilibria only.  相似文献

The Copeland rule and Condorcet’s principle   总被引:1,自引:0,他引:1  
Summary. The purpose of this note is to shed some light on the relationship between the Copeland rule and the Condorcet principle in those cases where there does not exist a Condorcet winner. It will be shown that the Copeland rule ranks alternatives according to their distances to being a Condorcet winner.Received: 30 July 2003, Revised: 31 December 2003, JEL Classification Numbers: D70, D71.Christian Klamler: I am very grateful to Daniel Eckert and Nick Baigent for their helpful comments.  相似文献

ABSTRACT

This article provides a summary account of Piero Sraffa’s constructive and interpretive work on the classical approach to the theory of value and distribution and its relationship with Marx’s contributions. It is shown that in the early phase of his constructive work Sraffa developed his equation systems by adopting a ‘physical real cost’ approach and a strictly objectivist point of view, and completely eschewed Marx’s labour-based approach and the related Marxian concepts. Only at a later stage did he explore systematically the relationship between his own modern re-formulation of the surplus approach to the theory of value and distribution and Marx’s contribution. He considered Marx’s most important analytical contribution to the further development of the surplus approach to consist of the re-integration of circular production relations, which allowed him to see the existence of a maximum rate of profits and its role in an analysis of accumulation and technical change.  相似文献

In times of convergence with regard to product functionality and performance, the appearance of a product constitutes an important source of competitive advantage. Astonishingly, only a few studies have empirically examined the relationship between design‐related aspects and firm value. Moreover, existing studies predominantly use accounting‐based and/or subjective performance measures. Against this background, the present work assesses the contribution of the three most important product design dimensions (i.e., aesthetic, ergonomic, and symbolic value) to the creation of firm value in the context of the automotive and consumer electronics industry. To do so, we examine stock market reactions to the unveiling of a new product's appearance to the public using event study methodology. In particular, we combine perceptual data at the consumer level with stock market data to examine how target consumers' perceptions of the aforementioned design dimensions are related to abnormal returns following the unveiling of a new product. Results reveal that ergonomic value is positively related to abnormal returns, while aesthetic value only exerts a significant positive effect on abnormal returns if the product also exhibits a certain degree of functional product advantage. Finally, symbolic value exerts a negative influence on stock market reactions. These findings have important implications for the allocation of design‐related investments to aesthetic, ergonomic, and symbolic design features.  相似文献

In the last decade, transparency has become a necessary mantra for both publicly listed companies and government institutions. Intellectual capital reporting is often related to this goal of enhancing the transparency of business and public institutions. In this paper we emphasize that a movement is seen in the intellectual capital reporting debate, which we argue can be approached as two different discourses of transparency, namely one discourse based on generic reporting versus a second discourse based on management driven information. In other words, one discourse highlights as much information to stakeholders as possible, but seems to be in the process of being substituted by another, which emphasizes reporting what is seen from the perspective of management, namely the “right” information, and only that. The argument for the latter discourse is that it will make intellectual capital reporting more transparent, because of users’ bounded rationality and other constraints such as time. This, however, has the implication that users of intellectual capital reporting may become victims of management's selected “right” information, by [Strathern, M. The tyranny of transparency. British Educational Research Journal 2000;26:310–32] designated as the “tyranny of transparency”. Also, we emphasize the problems of perceiving transparency as a goal and not a means.  相似文献

Under minimal assumptions, finite sample confidence bands for quantile regression models can be constructed. These confidence bands are based on the “conditional pivotal property” of estimating equations that quantile regression methods solve and provide valid finite sample inference for linear and nonlinear quantile models with endogenous or exogenous covariates. The confidence regions can be computed using Markov Chain Monte Carlo (MCMC) methods. We illustrate the finite sample procedure through two empirical examples: estimating a heterogeneous demand elasticity and estimating heterogeneous returns to schooling. We find pronounced differences between asymptotic and finite sample confidence regions in cases where the usual asymptotics are suspect.  相似文献
