The Federal Communications Commission (FCC) spectrum auctions use a simultaneous ascending auction design. Bidders bid on numerous communication licenses simultaneously, with bidding remaining open on all licenses until no bidder is willing to bid higher on any license. With full revelation of bidding information, simultaneous open bidding allows bidders to send messages to their rivals, telling them on which licenses to bid and which to avoid. These strategies can help bidders coordinate a division of the licenses, and enforce the proposed division by directed punishments. We examine solutions to mitigate collusive bidding in the spectrum auctions, and then apply these ideas to the design of daily electricity auctions.  相似文献

We use the US International Trade Commission's uniquely detailed 1995–2007 Chinese Customs data to better understand the pattern of trade between China and its two largest trading partners, Japan and the United States. Our review finds that only a small share of these flows can be characterized as arm's length, one-way trade in final goods. Instead, we find extensive two-way trade, deep vertical specialization, concentration of trade in computer and communication devices, and a prominent role for foreign-invested enterprises. While these characteristics define both bilateral relationships, important differences between the two pairs do emerge, suggesting that trade costs influence the method by which multinationals choose to integrate their production with China. Consequently, we argue that dialogue on East Asian trade liberalization should include the possibility of significant production gains for the US from its inclusion in any regional agreements.  相似文献

The shift toward individualistic career management requires a supportive and developmental career approach. Using coaching practices as a manifestation of such an approach, this study reports on coaching and other career practices that are part of supportive and developmental career management in a Belgium sample (n = 154). Three other types of career management were identified as well. Supportive and developmental career management was most present in organizations that had a past or current prospector strategy, and was the least present in past or current defenders. The type of business strategy organizations indicated to pursue in the future did not have an influence on the type of career management they currently had. © 2012 Wiley Periodicals, Inc.  相似文献

This paper presents data from an in-depth study conducted among street children in an urban setting in Tanzania. It examines the reasons ‘children of the street’ leave their homes, how they survive and meet their daily needs, what problems they encounter whilst on the streets and how they surmount them. The paper also examines the implications of street life for children’s health. The findings show that general poverty lies at the center of the increasing number of street children in Tanzania. Street life makes the children vulnerable to a variety of problems including ill health. Policies in Tanzania have so far failed to solve this problem, particularly because social policies have been dealing with symptoms rather than essential causes. The paper ends by outlining short- and long-term policy solutions and also suggests directions for future research and early intervention. — Cet article présente les données d’une étude en profondeur conduite parmi les enfants des rues dans un cadre urbain en Tanzanie. Il explore les raisons pour lesquelles ‘les enfants des rues’ partent de chez eux, comment ils survivent et surviennent à leurs besoins quotidiens, les problèmes qu’ils rencontrent dans les rues et comment ils les surmontent. Cet article examine aussi les implications de la vie dans la rue pour la santé des enfants. Les résultats montrent que la pauvreté générale est la raison centrale du nombre croissant d’enfants dans les rues en Tanzanie. La vie dans les rues rend les enfants susceptibles à de nombreux problèmes, y compris la mauvaise santé. La politique de la Tanzanie n’a pas encore réussi à résoudre ce problème, en particulier parce que la politique sociale a adressé les symptômes plutôt que les causes essentielles. Cet article propose des solutions politiques à court et à long terme et suggère également des options pour les recherches futures et pour des interventions précoces.  相似文献

Investor-driven 'short-termism' is said to harm EU public firms' ability to invest for the long term, prompting calls for the EU to better insulate managers from shareholder pressure. But the evidence offered—rising levels of repurchases and dividends—is incomplete and misleading: it ignores large offsetting equity issuances that move capital from investors to EU firms. We show that, over the last 30 years and the last decade, net shareholder payouts have been moderate and investment and cash balances have increased. In sum, the data provide little basis for the view that short-termism in the EU warrants corporate governance reforms.  相似文献

We find that mutual funds located in regions with more competing funds charge lower management fees, but higher fees related to sales and distribution (12b‐1 fees), sales loads, and other nonmanagement fee expenses. There is some evidence that funds in more competitive regions have higher total expense ratios than similar funds in less competitive regions. Our results indicate that while increased competition drives down fund profits, it creates a negative externality by way of increased sales expenses. Overall, our results suggest the mutual fund industry is characterized by monopolistic competition determined at the local level.  相似文献
