A simple example shows that equilibria can fail to exist in second price (Vickrey) and English auctions when there are both common and private components to bidders’ valuations and private information is held on both dimensions. The example shows that equilibrium only exists in the extremes of pure private and pure common values, and that existence in standard models is not robust to a slight perturbation.  相似文献

This research explores the variation of new product quality and risk associated with New Product Development (NPD) entry strategies (e.g. in‐house developments and joint ventures). Our first two research questions examine the quality of new products and the variation of risk across five NPD entry strategies. Our third and fourth research questions investigate the association of the proficiency with which NPD technical activities are performed with new product quality and the risk involved in developing new products. Our final two research questions explore whether the type of NPD entry strategy mediates the association between the proficiency with which NPD technical activities are performed and the quality and risk associated with the development of new products. Our study focuses on new products developed by three major industries, namely medical devices, electrical equipment, and heavy construction equipment. Our research suggests that there is no difference in the quality or the risk associated with the development of new products across NPD entry strategies. We also found that new product quality was associated with the proficient performance of many NPD technical activities whereas risk was associated with the proficient performance of fewer NPD technical activities. We found that choice of NPD entry strategy mediates the relationship between new product quality and NPD technical activity proficiency. Unlike product quality, NPD entry strategy selection appears to mediate NPD risk minimally. Our study contributes to NPD knowledge and managerial decision making by pointing out that the technical activities performed during the early stages of the NPD process are important to the attainment of a quality product and positively, not negatively, associated with perceived NPD risk. Additionally, our study extends knowledge of the association between proficiently performed NPD technical activities and the resultant product quality and perceived risk felt when individual NPD entry strategies are implemented.  相似文献

We introduce a quantile regression approach to panel data models with endogenous variables and individual effects correlated with the independent variables. We find newly developed quantile regression methods can be easily adapted to estimate this class of models efficiently.  相似文献

Using a sample of 978 quarterly management earnings-per-share forecasts made during the period 1993 to 1999, we document that financial analyst revisions to management earnings forecasts are a function of management forecast form. More precise forecasts (measured three different ways) lead to greater revision of financial analyst consensus EPS forecasts for a given level of unexpected earnings as predicted by Kim and Verrecchia (1991) and Bayesian adjustment models. Also, consistent with our arguments, maximum forecasts are interpreted as bad news by analysts. Our results, while consistent with theory, are inconsistent with recent experimental studies which do not reject the null hypothesis of no effect of management earnings forecast form on the association between unexpected earnings and financial analyst forecast revisions. We also re-examine Baginski, Hassell, and Kimbrough's (2004) finding that attributions used to explain management forecasts affect the reaction to the forecast using analyst data. Consistent with their findings using stock prices, the attribution presence (especially external attributions) increases financial analyst revisions pursuant to management forecasts.  相似文献

In 1993 a new page was turned in national accounting. The United Nations Standards of National Accounting recommended a new standard for the measurement of output from the public sector. Implementation has recently begun in many countries, in Europe based on a European Union directive. In the U.K. the Atkinson Review in 2005 came up with a series of recommendations. This article examines its recommendations concerning the definition and valuation of government outputs. For the non‐market sector a market analog is recommended by the Review. However, several of its recommendations are inconsistent with that, championing social value as a basis for definitions and measurement. If taken seriously it will lead to arbitrary and politically controversial factors inserted into national accounts. The article highlights the norm that GDP is a measure of production, and advocates adhering to the market analog and following well recognized practices of national accounting.  相似文献

Abstract.  Edgeworth showed that a free-trading country might be impoverished by its own technical improvements if they are confined to the export industry and if no good is inferior in consumption. More recently it has been shown that improvements confined to the country's import competing industry can never be impoverishing if, in that country, no commodity is inferior in consumption. However, in all available proofs of these propositions, it has been assumed that for each country there exists an autarkic equilibrium. It will be shown that, without that assumption, the second proposition must be severely qualified.  相似文献

This article reads Ohmae's arguments about ‘the end of the nation‐state’ against the arguments of Luttwak about the centrality of ‘geoeconomics’ in the new world order. By exploring the limits of both their arguments, the article develops a much more critical account of geoeconomics, suggesting that it can be used by scholars of boundaries and geopolitics to come to terms with the development of cross‐border regionalism and associated transnational state effects (i.e. transnational governance imperatives) in the context of free trade. Geoeconomics is thus argued to describe the localised changes in governance imperatives implicated in a series of economically‐driven and quite quotidian challenges to national borders on the ground in both North America and Europe. The article outlines how an examination of localised strategies to create cross‐border regions in the context of globalised economic interdependencies offers a research window onto processes currently challenging the nation‐state from the ground up. As such, it is argued that the case studies discussed here also offer a way of empirically evaluating the geoeconomic influence of discourses about ‘the end of the nation‐state’ promoted by writers such as Ohmae.  相似文献

Animal farming exceeds all forms of transport in terms of global greenhouse gas (GHG) emissions. Despite the implications of the seriousness of addressing animal farming in relation to mitigating the effects of GHG emissions, to date, the relationship between consumer behaviour and climate change has tended to neglect the role of animal foods. This paper reports on a pilot study in which six UK households were ‘shadowed’ to facilitate the investigation of the relationship between animal food practices and environmental practices, as they emerge in day‐to‐day life. Results indicate that most participants make no connection between the two issues at present, in terms of awareness or practice. However, animal foods do have an ambiguous and complex status in most participants' food practices; for instance, being viewed as problematic for reasons of health or animal welfare. This finding suggests that further research is needed into the potential for raising awareness of the link between animal‐based foods and climate change. This might have a role to play in shifting food practices towards more plant‐based, less GHG intensive, foods.  相似文献
