Federal funds and eurodollar futures contracts are among the most useful instruments for deriving expectations of the future path of monetary policy. However, reading policy expectations from those instruments is complicated by the presence of risk premia. This paper demonstrates how to extract the expected policy path under the assumption that risk premia are constant over time, and under a simple model that allows risk premia to vary. In the latter case, the risk premia are identified under the assumption that policy expectations level out after a long enough horizon. The results provide evidence that the risk premia on these futures contracts vary over time. The impact of this variation is fairly limited for futures contracts with short horizons, but it increases as the horizon of the contracts lengthens. © 2004 Wiley Periodicals, Inc.

This paper addresses the supply-side explanations of a logger shortage by estimating an occupational choice model that considers the role of earnings, nonpecuniary determinants and intergenerational factors. Our results showed that: (1) relative earnings have no statistically significant effect on career choice; (2) improvement in the public image of loggers substantially increases entry into logging; and (3) a strong intergenerational supply linkage exists but is currently being eroded. 相似文献

Strategic management research has been characterized as placing less emphasis on construct measurement than other management subfields. In this work, we document the state of the art of measurement in strategic management research, and discuss the implications for interpreting the results of research in this field. To assess the breadth of measurement issues in the discipline, we conducted a content analysis of empirical strategic management articles published in leading journals in the period of 1998–2000. We found that few studies discuss reliability and validity issues, and empirical research in the field commonly relies on single‐indicator measures. Additionally, studies rarely address the problems of attenuation due to measurement error. We close with a discussion of the implications for future research and for interpreting prior work in strategic management. Copyright © 2004 John Wiley & Sons, Ltd. 相似文献

Reform of agricultural policies, notably the continuing elimination of production‐enhancing subsidies, makes it possible for policies to respond to social issues such as the rural environment and health in future. In this paper, we draw on a Rural Economy and Land Use (RELU) research project which is examining the potential for the development of healthy food chains and the implications for human health and the environment. One of the key issues to be addressed is consumers’ willingness to pay for the nutritionally enhanced food products from these new chains, but it is evident that only a partial understanding can be gained from a traditional economics approach. In the paper, we discuss how economists are beginning to incorporate views from other disciplines into their models of consumer choice. 相似文献

Gartner观点:Gartner的专家们认为直至2003年Web服务才能真正发展起来。2003年全球40%的电子商务贸易将利用Web服务来完成,2004年这一数字将超过50%,而交易时间将大大缩短。2003年大约80%的开发平台将支持Web服务体系,Web服务将代表下一代软件开发平台的发展方向。据调查显示,在创建Web服务应用程序时,有78%的人使用的是J2EE,并且认为它是最有效的创建和配置Web服务的平台;而使用微软.Net的人为22%。从中我们似乎可以看出哪一个平台更适合于Web服务,哪一个平台又更适合于大多数的开发者。这两个平台的竞争,在2002年愈演愈烈。 相似文献
