There have been a number of empirical attempts to account for variation in exchange rate regime choice, but these attempts point in several directions and are not made sense of easily. One reason for the differences among studies is that standard statistical techniques are unable to identify the nonlinear and contingent relationships among the factors that influence the choice of exchange rate regime. This article utilizes a statistical technique that reveals complex nonlinear interactions among variables. The analysis reveals that the influence of past inflation acts to condition the influence of labor market rigidity and that political stability plays a key role for both high and low inflation countries.  相似文献

Literature-related discovery (LRD) is the linking of two or more literature concepts that have heretofore not been linked (i.e., disjoint), in order to produce novel, interesting, plausible, and intelligible knowledge (i.e., potential discovery). The open discovery systems (ODS) component of LRD starts with a problem to be solved, and generates solutions to that problem through potential discovery. We have been using ODS LRD to identify potential treatments or preventative actions for challenging medical problems, among myriad other applications. The five immediately preceding papers in this Special Issue describe the application of ODS LRD to Raynaud's Phenomenon (RP), cataracts, Parkinson's Disease (PD), Multiple Sclerosis (MS), and Water Purification (WP). We describe the lessons learned from each application, and how the techniques can be improved further.Generation of much potential discovery using ODS LRD is possible when the conceptual roadblocks to discovery are removed. Some of these roadblocks include use of numerical filters that are unrelated to generating discovery, and excessive reliance on literatures directly related to the problem literature of interest. The issue of how to handle large amounts of potential discovery has not been addressed in the literature, since most ODS LRD researchers have tried to find a relatively few potential discovery items. We present a development strategy that capitalizes on the large amounts of potential discovery we have identified.  相似文献

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

ABSTRACT

Clear and well-defined patent rights can incentivize innovation by granting monopoly rights to the inventor for a limited period of time in exchange for public disclosure of the invention. However, with cumulative innovation, when a product draws from intellectual property held across multiple firms (including fragmented intellectual property or patent thickets), contracting failures may lead to suboptimal economic outcomes. However, an alternative theory, developed by a variety of scholars, contends that patent thickets have a more ambiguous effect. Researchers have developed several measures to gauge the extent and impact of cumulative innovation and the various channels of patent thickets. This paper contends that mis-measurement may contribute to the incoherence and overall lack of consensus within the patent thickets literature. Specifically, the literature is missing a precise measure of vertically overlapping claims. We propose a new measure of vertically overlapping claims that incorporates invention similarity to more precisely identify inventive overlap. The measure defined in this paper will enable more accurate measurement, and allow for novel economic research on cumulative innovation, fragmentation in intellectual property, and patent thickets within and across all patent jurisdictions.  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
