Before last year's dot-com meltdown, one of the most hyped areas was large industry-based business-to-business (B2B) marketplaces. Most of these have either failed or are struggling. Instead, the growth today is in less ambitious online auctions where individual firms, increasingly having to focus on costs, seek suppliers of the products or services they need. FreeMarkets, growing fast though still unprofitable, is the leader in this growing field. This case discusses the problems and potential not only for FreeMarkets itself but also for the buying and selling companies which use it.  相似文献

We extend Hotelling’s model of spatial competition by adding an outside good, provided by a webshop. Unlike the commonly used reservation price, the price of the webshop is endogenous. We establish that a Nash equilibrium exists if the outside good is not too different from the goods sold by the bricks-and-mortar shops. Equilibrium prices positively depend on transport costs, which would not be the case for an exogenous reservation price. If the webshop serves an alternative market as well, the price of that market is partly imported into the local market. The bricks-and-mortar shops compete only with the the webshop. The lower the webshop’s delivery costs are relative to the transport cost parameter, the wider the feasible range for locations of the bricks-and-mortar shops.  相似文献

When‐issued (i.e., forward) trading in T‐bills yet to be auctioned provides a unique environment for examining price discovery. Because T‐bills are auctioned in a sealed‐bid process, when‐issued traders cannot observe the spot market price. Yet the forward price must ultimately converge on the auction outcome price. Our results indicate that traders in the when‐issued market “discover” the ultimate auction price. Little evidence is found that standard order flow variables contribute to price discovery. Instead, the ability to observe a few trades with relatively small volume in the when‐issued market is sufficient to discover the auction price resulting from the sealed‐bid process.  相似文献

Probably one of the most controversial contributions to the literature of international trade theory was offered by the late social economist John Culbertson. In his view, low wage competition among corporations in a world characterized by capital mobility and massive trade deficits undermines the foundation trade theory based on David Ricardo’s celebrated notion of comparative advantage. Instead, there are several good reasons to believe that international trade with China, India, Vietnam, etc. will be governed by absolute advantage. The current essay is dedicated to the virtually ignored work of Culbertson, and it is meant as an invitation for social economists to critically evaluate the argument and in the process make an attempt to point out where it goes wrong.  相似文献

Injuries are among the leading causes of death and disability worldwide. The burden caused by injuries is even greater among the poorer nations and is projected to increase. Very often the lack of technical and financial resources, as well as the urgency of the problem, preclude applying sophisticated surveillance and research methods for generating relevant information to develop effective interventions. In these settings, it is necessary to consider more rapid and less costly methods in applying the public health approach to the problem of injury prevention and control. Rapid Assessment Procedures (RAP), developed within the fields of epidemiology, anthropology and health administration, can provide valid information in a manner that is quicker, simpler, and less costly than standard data collection methods. RAP have been applied widely and successfully to infectious and chronic disease issues, but have not been used extensively, if at all, as tools in injury control. This paper describes Rapid Assessment Procedures that (1) are useful for understanding the scope of the problem and for identifying potential risk factors, (2) can assist practitioners in determining intervention priorities, (3) can provide in-depth knowledge about a specific injury-related problem, and (4) can be used in surveillance systems to monitor outcomes. Finally, the paper describes some of the caveats in using RAP.  相似文献

Recent corporate scandals have focused the attention of a broad set of constituencies on reforming corporate governance. Boards of directors play a leading role in corporate governance and any significant reforms must encompass their role. To date, most reform proposals have targeted the legal, rather than the ethical obligations of directors. Legal reforms without proper attention to ethical obligations will likely prove ineffectual. The ethical role of directors is critical. Directors have overall responsibility for the ethics and compliance programs of the corporation. The tone at the top that they set by example and action is central to the overall ethical environment of their firms. This role is reinforced by their legal responsibilities to provide oversight of the financial performance of the firm. Underlying this analysis is the critical assumption that ethical behavior, especially on the part of corporate leaders, leads to the best long-term interests of the corporation. We describe key components of a framework for a code of ethics for corporate boards and individual directors. The proposed code framework is based on six universal core ethical values: (1) honesty; (2) integrity; (3) loyalty; (4) responsibility; (5) fairness; and (6) citizenship. The paper concludes by suggesting critical issues that need to be dealt with in firm-based codes of ethics for directors.  相似文献

The 'fashionable' concept of lean production has been discussed more intensively in Germany than elsewhere in Europe but has resulted not only in rationalisation measures such as downsizing and delayering but also in implementing 'Gruppenarbeit'. Through interpretation processes at different levels, the outcomes of action undertaken in the name of a concept can become loose-coupled to its original meanings. Fashion's 'interpretive viability' allows for this.  相似文献

Central Asia has experienced massive economic and social shocks during the past decade following the dissolution of the former Soviet Union. Demand for cereals, particularly for staple cereals and meats, has fallen significantly even as production and productivity have plummeted. Although agricultural reforms were launched in 1991, the performance of the agricultural sector has been weak across the region. Prospects for food security in Central Asia appear mixed. Projections indicate that a growing and urbanizing population in Central Asia with rising incomes will increase demand for cereals by 32% between 1995 and 2020 to reach 24 million tons, and for meat by 47% to reach 2.9 million tons. Improvements in crop productivity will be essential to meet the increases in demand projected for the region. Cereal production is forecast to keep pace with demand such that Central Asia will be virtually self-sufficient in cereals. However, national food self-sufficiency or food security does not necessarily translate into household or individual food security. Moreover, self-sufficiency comes with a high price-tag of opportunities foregone and inappropriate use made of resources. Given the growing enthusiasm for food self-sufficiency in Central Asia, it is imperative that research be undertaken to assess the full costs and benefits of such a policy.  相似文献

Plans for trade liberalization within the Asia–Pacific Economic Co-operation (APEC) Forum include the elimination of all tariffs between member states. The study in this paper uses two computable general equilibrium models to examine the effects of these plans, focusing on China. The modelling shows that liberalization increases China's capital stock and real GDP. The implication for Chinese industries depends on the extent to which liberalization exposes them to additional import competition. Industries strongly stimulated include textiles and communications equipment. Transport equipment is the most adversely affected. Chinese regional results follow from the industrial compositions of the regions, with Zhejiang the most favourably affected and Jilin the least.  相似文献
