Property rights theory predicts that private firms whose ownership shares are not tradable will not be managed efficiently. This paper tests that theory by comparing the costs of rural electric cooperatives (RECs) and investor-owned electric utilities (IOUs). Separate translog cost functions are estimated for the RECs and the IOUs. The estimated costs of producing several three-product output bundles are then compared across ownership form under the assumption that all firms face identical input prices. The empirical results suggest that the cooperative sector of the electric power industry produces its output in a much less efficient manner than does the investor-owned sector.I would like to thank David Kaserman, Steven Caudill, T. Randolph Beard, Daniel Gropper, and David Laband for their many helpful comments on earlier drafts of this paper. This research was partially funded by the Auburn University Utilities Research Center.

This paper develops twenty hypotheses concerning the relationships among selected individual differences variables (locus of control, delay of gratification, gender, and race) and five different ethical beliefs. The results of a study of collegians provide support for seventeen out of twenty research hypotheses. As predicted, locus of control, delay of gratification, and race are related to ethical beliefs. Also as predicted, gender is not related to ethical beliefs. Michael K.

A bstract . Historical comparisons between the USSR and US economies most often focus on the stark contrasts between market and centrally controlled systems. However, expediency in response to dynamic pressures caused the adoption of central planning in both countries. Additionally, the USSR's lackluster economic performance when wedded to Marxism caused institutional arrangements to move toward markets. After summarizing USSR's central planning experiences before 1965, its similarity to the US's wartime planning is discussed. These comparisons provide insights into the problems of moving between market and planned economies  相似文献

Social Networks and Economic Sociology   总被引:12,自引:0,他引:12  
A bstract The social network metaphor is widely used by sociologists to study socioeconomic behavior and processes The use of social networks generally takes place within the ranks of sociology However, a more complete social science would result by combining work being done on social networks within sociology with mainline economic theory The insights from such a research agenda will help us better understand socioeconomic behavior With this in mind, the main objective of this paper is to demonstrate the utility of the network metaphor to economists This objective will be accomplished through developing four basic components of social networks, and using them to navigate through the existing literature in economic sociology Furthermore, topics for future research in which social networks can provide contributions to the explanation of socioeconomic behavior are explored as well  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

Until the stock market bubble burst in 2000–2002, most CFOs viewed their defined benefit pension plans as profit centers and relatively risk‐free sources of income. Since neither pension assets nor liabilities were reported on corporate balance sheets, and expected returns on pension stocks could be substituted for actual returns when reporting net income, the risks associated with DB plans were masked by GAAP accounting and thus assumed to have no bearing on corporate capital structure. But when stock prices and corporate profits fell together, the risks associated with conventional stock‐heavy pension plans showed up first in reduced pension surpluses (or, in many cases, deficits) and then later in higher required cash contributions and lower reported earnings. As a consequence, today's investors (and rating agencies) are viewing pension and other legacy liabilities as corporate debt, and demands for transparency and increased funding have triggered accounting changes and proposed legislative reforms that will further unmask the economics. This article aims to provide both private‐sector and public‐sector CFOs with suggestions for reducing and controlling the cost of providing for the retirement of their employees. Profitable, tax‐paying companies with DB plans should consider (1) funding any unfunded liabilities (if necessary, by issuing debt) and (2) reducing pension equity and interest rate exposures by shifting some (if not all) pension assets into bonds and defeasing the pension liability (achieving a tax arbitrage in the process). And in cases where the expected costs of maintaining DB plans outweigh the benefits, companies should consider freezing or terminating their plans and switching to a defined contribution (DC) or some form of hybrid plan. The authors also propose similar changes for public pension plans, where underfunding and mismatch problems are greater, less transparent, and in some ways less tractable than those of corporate DB plans.  相似文献
