This paper focuses on an emissions permit market dominated by one firm and with a government concerned about social efficiency and permits revenue. In this setting, it is shown that the dominant firm's market power reduces the opportunities for the government to raise non-distortionary revenue from permits without loss of consumer surplus. Since the government's objectives are thus hampered in auctioning permits, the dominant firm should be excluded from the auction. Specifically, the regulator should sell permits directly, through bilateral negotiation, to the dominant firm, and auction off the remaining permits to the fringe firms.  相似文献

Open Source Software projects base their operation on a collaborative structure for knowledge exchange in the form of provision or reception of information, expertise and feedback on the creation of source code. Here, we address the direction of these knowledge flows among projects throughout social networks and their impact on project success. We identify the roles of membership or contribution that individuals play within projects. We found that connections through contributors who bring their knowledge to the project, improve project success, and that connection through members, who transfer their knowledge towards other projects, enhance project success. Finally, we found that ties through shared membership and contributions hamper project success. The analysis of knowledge flows and their impact on project success imply a translation of returns from investment in social capital, where investment takes the shape of knowledge flows and the returns mean the projects’ diffusion over the network.

In an economy with private information, we introduce the notion of objects of choice as lists of bundles out of which the market selects one for delivery. This leads to an extension of the model of Arrow–Debreu that is used to study trade ex ante with private state verification. Under the assumption that agents are prudent, equilibrium is characterized by the fact that agents consume bundles with the same utility in states that they do not distinguish. This is a weaker condition than the restriction of equal consumption imposed by Radner (Econometrica 36(1), 31–58, 1968), therefore, some no trade situations are avoided and the efficiency of trade increases.  相似文献

We produce a solution to the problem of extending a quasiordering conditional on a finite list of ex-ante comparisons between pairs. This constitutes yet another extension of the classical Szpilrajn’s theorem. Some examples of use of our result follow.  相似文献

This paper is concerned with the robustness of equilibrium exchange rate estimations based on the BEER approach for a set of both industrial and emerging countries. The robustness is studied in four directions, successively. First, we investigate the impact of using alternative proxies for relative productivity. Second, we analyze the impact of estimating the equilibrium equation on one single panel covering G20 countries, or separately for G7 and non-G7 countries. Third, we measure the influence of the choice of the numeraire on the derivation of bilateral equilibrium rates. Finally, we study the temporal robustness of the estimations by dropping one or 2 years from the estimation period. Our main conclusion is that BEER estimations are quite robust to these successive tests, although at one point of time misalignments can differ by several percentage points depending on the methodology. The choice of the productivity proxy is the most sensible one, followed by the country sample. In contrast, the choice of the numeraire and the time sample have a relatively limited impact on estimated misalignments.  相似文献

This paper is organized as follows: first, we show that the reference to the notion of group selection is coherent with the other parts of Hayek’s thought. Second, we develop the idea that recent works in terms of the emergence and evolution of social norms corroborate in part Hayek’s theses in this domain. Finally, we put to the fore some drawbacks in Hayek’s approach and propose means to solve them.

As capitalist economies have shifted their primary focus from providing goods and services for all, to concentrating wealth at the top echelons of societies, social entrepreneurs have been one source of re-capturing the original intent of capitalism. Social entrepreneurs have combined the efficiency and effectiveness of business organizations with the social concerns of many non-profit and governmental agencies. As a result, social entrepreneurship is viewed as having significant potential for alleviating many of the social ills we now face. To accomplish this mission, however, will require expansion of social enterprises beyond their current footprints. We explore alternate methods of expansion, scaling and replication, and then examine potential catalysts, which can enable social entrepreneurs to attain their goals of social improvement. The catalysts we identify are effectual logic, enhanced legitimacy through appropriate reporting metrics, and information technology. We conclude with two brief case studies that exemplify how these catalysts are currently working to enhance the effectiveness of social start-ups.  相似文献

This article introduces an integrative framework of corporate social responsibility (CSR) design and implementation. A review of CSR literature – in particular with regard to design and implementation models – provides the background to develop a multiple case study. The resulting integrative framework, based on this multiple case study and Lewin’s change model, highlights four stages that span nine steps of the CSR design and implementation process. Finally, the study identifies critical success factors for the CSR process.  相似文献

Since it implies a reduction in the quality and the quantity of the natural resources, environmental degradation is a present day problem that requires immediate solutions. This situation is driving firms to undertake an environmental transformation process with the purpose of reducing the negative externalities that come from their economic activities. Within this context, environmental marketing is an emerging business philosophy by which organizations can address sustainability issues. Moreover, environmental marketing and orientation are seen as valuable strategies to improve a firm’s competitiveness. However, the literature that has analyzed the link between environmental strategies and firms’ results has been inconclusive and contradictory. In this study, we propose and test a model that analyses how the implementation of ecological issues within a firm’s marketing strategy and orientation influences organizational results. Data were obtained through a survey sent to Spanish manufacturing firms. The results show that environmental marketing positively affects firms’ operational and commercial performance and this improvement will influence their economic results. Moreover, environmental marketing is revealed as an excellent strategy to obtain competitive advantages in costs and in product differentiation. Thus, this study agrees with the researchers who affirm that environmental strategies positively affect firm’s competitiveness while reducing environmental impact.  相似文献
