This paper develops a case study approach that builds on the foundations of moderate constructionism and abduction. We discuss the case study method and its role in industrial marketing, especially in business-to-business networks. Moderate constructionism is compared with realist, critical realist, and relativist approaches. We argue that moderate constructionism takes better into account the multiple constructed, community-bounded realities that all case studies inevitably deal with. The power of moderate constructionism to produce valid and generalizable new knowledge is critically assessed. We also address abduction in relation to induction and deduction and its role in the moderate constructionist research approach. Finally, we develop a process model, illustrated by a case study of a specific network in the pharmaceutical industry.  相似文献

Non-parametric production analysis in non-competitive environments   总被引:1,自引:0,他引:1  
We extend the non-parametric methodology for empirical production analysis to deal with endogenous prices. As price endogeneity is often complemented by price uncertainty, we consider both the case of certain prices and the case of uncertain prices. The extensions are fully compatible with existing tools for eliciting and representing technology and price information, and preserves the tractable mathematical programming structure of the original methodology. An empirical application to the Dutch electricity distribution sector illustrates our extension.  相似文献

Finland experienced an extremely severe economic depression in the early 1990s. As a part of the government's crisis management policies, significant new legislation was passed that increased supervisory powers of financial market regulators and reformed bankruptcy procedures significantly decreasing the protection of creditors. We show that the introduction of these new laws resulted in positive abnormal stock returns. The new laws also lead to increases in firms’ Tobin's q, especially for more levered firms. In contrast to previous studies, our results also suggest that public supervision of financial markets fosters rather than hampers financial market development.  相似文献

This paper analyses the concept of coercion, understood as a special type of social power. Coercion uses threats to force the victim to obey the dominating agent, that is, to elicit an intentional response from the subordinate person. The typical decision environment is described and the effect of threats on utility distributions is analysed. Some causal aspects of threats are also discussed. The strategies of coercive threats are expressed in a game theoretical form. A paradox is revealed: the coercer can only seldom make his threat convincing to his intended victim. It is difficult to show that a rational agent (the coercer) would indeed realize his threat when he meets resistence. Different coercive state policies are then discussed in relation to this paradox and a solution is suggested. Finally, Steven Lukes' ideas concerning power are criticized.  相似文献

The empirical literature on production and cost functions is divided into two strands. The neoclassical approach concentrates on model parameters, while the frontier approach decomposes the disturbance term to a symmetric noise term and a positively skewed inefficiency term. We propose a theoretical justification for the skewness of the inefficiency term, arguing that this skewness is the key testable hypothesis of the frontier approach. We propose to test the regression residuals for skewness in order to distinguish the two competing approaches. Our test builds directly upon the asymmetry of regression residuals and does not require any prior distributional assumptions.  相似文献

For a company planning to become a mobile operator, two alternative ways to enter the market exist. In addition to the traditional way of acquiring a spectrum license and building a mobile network, market entrance is also possible by becoming a virtual operator and utilizing the existing networks of incumbent operators. Potentially, virtual operators will have an important role in shaping the mobile market structure and competition. In this paper, techno-economic modeling methods are used to analyze the position of virtual operators in the mobile communications industry. Four alternative virtual operator scenarios are constructed and analyzed using a linear, deterministic, and quantitative techno-economic model. The results highlight the importance of wholesale contracts with incumbent mobile network operators in determining the virtual operators’ business profitability. Unbalance in termination prices between fixed and mobile networks is shown to give incentives for virtual operators to invest in their own network infrastructure.  相似文献

Only anecdotal evidence exists that ventures use patents as collateral to access debt financing. In this paper, we use a novel dataset on patent reassignments with a security interest to explore quantitatively what patents are used as collateral. We analyze characteristics of patents to disentangle whether it is the technology underlying a patent or the patent's exclusion right per se matters for collateralization. We do find empirical support only for technology-related characteristics, suggesting that lenders use patents to collateralize high-quality technology that can, in case of default, be redeployed to ventures in similar technology fields. On the other hand, patent-related characteristics like scope, which are, in general, related to patent value and are particularly important for non-practicing entities, do not matter.  相似文献

Färe and Grosskopf (this issue) claim that a single abatement factor suffices for modeling weak disposability in nonparametric production models, and that the Kuosmanen (2005) technology that uses multiple abatement factors is larger than necessary. This article demonstrates by a numerical example that a single abatement factor does not suffice to capture all feasible production plans, and that its use leads to the violation of convexity, one of the maintained assumptions of the model. We also prove that the Kuosmanen technology is the correct minimum extrapolation technology under the stated axioms.  相似文献

This paper focuses on organizations and their management of climate risks. Climate risks stem from continued changes in climate means and the increase in frequency and intensity of extreme weather events. We ask whether companies also apply the usual process of corporate risk management to climate risks. In seeking to answer this question, we review several literature streams in order to set out an initial theoretical reflection. Based on this we conducted an exploratory case study with 11 electric utilities. Our results illustrate that these companies perceive climatic changes as a material issue for their business. However, management has restricted knowledge about such climatic changes and thus cannot precisely determine the potential negative impacts on business activities. As a consequence, the companies have implemented a climate risk management that does not differ from the usual process of managing other business risks. Our results further illustrate that there is some variation in how individual firms manage climate risks: While risk identification and risk assessment are equally important for all electric utilities, there are differences in how management determines the direction of the individual response to climate risks.
