This paper examines the idea of an online collaborative competition for solutions to environmental and social problems. It asks three basic questions: What is a collaborative competition? In what sense are collaborative competitions collaborative? And in view of the social and environmental goals of the competitions, are they a contribution to sustainability practice? Prepared by a conceptual analysis, partly drawing on the arguments for extended peer review in post-normal science, and based on the in-depth analysis of one collaborative competition, it is argued that the idea of a collaborative competition is innovative and suggestive; however, in practice there is only weak evidence for collaboration - the competitive element clearly prevails. The innovation, in practice, is a new way of making visible and thereby promoting social and environmental ideas. There is some evidence for collaborative spirit, but there is only limited evidence that arguments for extended peer review apply. The design of the online collaborative competition might not promote collaboration as well as it could. Therefore, the paper ends with a discussion of possibilities for changing the design of the competition.  相似文献

Abstract As we survey the literature of macroeconomic news in the foreign exchange market, we can by now look back on nearly 30 years of research. The first studies which analysed news effects on exchange rates were established in the early 1990s (see, for example, Dornbusch). Almost at the same time Meese and Rogoff published their influential paper, revealing the forecasting inferiority in exchange rates of structural models against the random walk. This finding has shocked the pillars of exchange rate economics and thus cast general suspicion on research focusing on fundamentals in this field. The eventual rising popularity of event studies can partly be attributed to the re‐establishment of the raison d’être of exchange rate economics. This work focuses on systematically surveying this literature with particular respect to its primary goal, i.e. shedding light on the analytical value of fundamental research. Thus, its major findings are, first, fundamental news does matter, whereas non‐fundamental news matters to a lesser degree. Second, news influences exchange rates via two separated channels, i.e. incorporating common information into prices directly or indirectly based upon order flow. Third, with a few exceptions the impact of fundamental news on exchange rates is fairly stable over time.  相似文献

Building on social movement theory, this study assesses the influence of social media activism on the stock market performance of targeted firms. We focus on information published on Twitter by two critical stakeholders: consumer associations and trade unions. To the extent that social media represent a valid medium to mobilize stakeholders' activism, protests on Twitter may damage firm reputation, leading to capital market reactions. Using a corpus of over 1.5 million tweets referring to Spanish listed banks, we study the impact of activism by looking at targeted firms' abnormal variations in price and trading volume. Our findings suggest that the Twitter activism of key stakeholders has a significant impact on investors' decisions. Further, our empirical analyses indicate that the mechanisms affecting investors' behavior differ depending on the characteristics of the stakeholder group. Hence, this study contributes to understanding how social movements influence corporate behavior via social media. Copyright © 2017 John Wiley & Sons, Ltd and ERP Environment  相似文献

Cooperation in several phases of the innovation process is viewed by antitrust authorities with suspicion. They face the dilemma between providing the right incentives for the appro-priability of returns to R&D and the risks of diminishing product market competition. The current legislation in the European Union and the United States gives special treatment to cooperation in R&D and the joint exploitation of results (extended cooperation).

We study several collusive regimes for a class of examples in which vertical relations are explicitly introduced. Regarding antitrust policy implications we fmd that: a) there is an ana-lytical justification to a ‘rule of reason’ treatment for extended cooperation in research joint ventures and, b) individual exemptions, though restrictive of competition, might be welfare improving.  相似文献

Labour market and social policies both affect and are affected by the process of trade liberalization and globalization. This two‐way interaction and the feedback effects are the focus of this paper. The analysis is mainly conceptual—but examples are illustrated throughout, based mainly in the context of labour markets in North America, Latin America and the Caribbean basin. Attention is paid to outlining the mechanisms whereby globalization and trade liberalization affect labour market and social policy initiatives, and the extent to which these pressures will lead to a harmonization of legislative and policy initiatives, and if that harmonization will necessarily be downward to the lowest common denominator. The paper concludes that: (1) the pressures will lead towards policy harmonization; (2) the harmonization generally will be downwards; (3) such harmonization is not always negative as generally perceived; (4) efficient regulatory and social policy initiatives will survive and indeed expand, with the “rent‐protecting” ones under most pressure to dissipate; and (5) pure distributional or equity‐oriented initiatives that have no positive feedback effect on efficiency, unfortunately, will also be under jeopardy to dissipate, and this is a serious policy concern. Alternatives for addressing this concern are discussed, as are their associated problems.  相似文献

Macroeconomic policy decisions in real-time are based on the assessment of current and future economic conditions. Crucially, these assessments are made difficult by the presence of incomplete and noisy data. The problem is more acute for emerging market economies, where most economic data are released infrequently with a (sometimes substantial) lag. This paper evaluates nowcasts and forecasts of real GDP growth using five models for ten Latin American countries. The results indicate the flow of monthly data helps to improve forecast accuracy, and the dynamic factor model consistently produces more accurate nowcasts and forecasts relative to other model specifications, across most of the countries we consider.  相似文献

The Asiento was an agreement between the Crowns of England and Spain of tremendous economic and political consequences. In spite of its importance, very little is known about the accounting practices of the Asiento. This paper demonstrates that the developments of the Asiento were very much linked to the lack of accountability of the South Sea Company (SSC) before the Spanish Crown and describes the characteristics of the accounting system used by the SSC to provide information on its developed economic activity. It also discusses the role of accounting in the resolution of conflicts between the tenants of the Asiento, the SSC and its Spanish counterparts.  相似文献

The item response theory (IRT) also known as latent trait theory, is used for the development, evaluation and administration of standardized measurements; it is widely used in the areas of psychology and education. This theory was developed and expanded for over 50 years and has contributed to the development of measurement scales of latent traits. This paper presents the basic and fundamental concepts of this IRT and a practical example of the construction of scales is proposed to illustrate the feasibility, advantages and validity of IRT through a known measurement, the height. The results obtained with the practical application of IRT confirm its effectiveness in the evaluation of latent traits.  相似文献
