We investigate why new, high-risk technologies can attract excessive and often unprofitable investment. We develop an equilibrium model in which rational, risk-averse agents overinvest in a risky technology, possibly to the point that its expected return is negative. Overinvestment results from relative wealth concerns which arise endogenously from the imperfect tradability of future endowments. Competition over future consumption leads to an indirect utility for wealth with “keeping up with the Joneses” properties that can induce herding. Because overinvestment increases with the risk of the technology, our model can explain why new, risky technological innovations may promote investment bubbles.  相似文献

The English (Association) Football League is a long established industrial cartel selling a highly popular product with only imperfect substitutes. Despite that, the majority of its member clubs lose money and the industry has faced successive financial crises over the last decade. This paper develops an empirical model of the financial performance of English League clubs using a high quality dataset of 48 clubs over the period 1974–89. The underlying model explains how rents are competed away through the maximising behaviour of club owners subject to production constraints. This model is parameterised by a system of equations which describe the behaviour of a maximising owner subject to demand and production constraints. The model is then used to examine the coordination failure which lies at the heart of the English Football League's decline and to assess the prospects for the Premier League.  相似文献

A bstract . A simple framework is presented for the analysis of the local employment, income, sales , and local government impacts of landing North Sea gas at either of two Norwegian kommunes (municipalities). These impacts indicate the different forms of economic change arising from a major economic development event. The average annual net change in these economic measures is estimated for the operational phase of a gas terminal. The analysis indicated substantial differences in local and regional net gains. Both sites yielded positive neteconomic gains, which means noneconomic and national considerations become key decision determinates. These national issues provide the setting to judge the local/regional net gains. The unresolved questions include the national benefits and costs of the landing decision given the small scale of the Norwegian economy, potential future gas finds, and a fully employed economy.  相似文献

This article examines how trade union membership varies across 16 OECD countries in the 1980s. Higher density of membership is found to be associated with a higher degree of centralisation of wage bargaining, higher percentage of employees covered by collective bargaining, a larger public sector and a more leftist party of government.  相似文献

The author, an advocate of CDT testing for insurance applicants, senses considerable uncertainty among medical directors concerning the value of the test. This review of CDT literature and the history of CDT testing in insurance laboratories is an attempt to mitigate that confusion. Two principle problems are identified: 1) the expected sensitivity of the CDT test in insurance applicants will be 50% at most, usually considerably less. 2) adapting CDT testing to commercial laboratories has been, and still is, an unsolved problem for there remains an important disparity between the method used at Clinical Reference Laboratories and LabOne. Other important issues are also reviewed: gender differences, ethnicity, LFT's and CDT, and technical facts.  相似文献

This article investigates the role of the annual report and the annual general meeting (AGM) in the context of NHS trusts. The authors report the results of a questionnaire survey of every NHS trust in the UK. Significant variation in the approach taken within a common framework of accountability was found. In general, there seems to be little public demand for trusts' annual reports and attendance at their AGMs was low. The research indicates possibilities of extending annual reporting in the public sector beyond the annual report and AGM and discloses innovative ways that trusts have attempted to overcome the limited interest of stakeholders produced by the traditional reporting mechanisms.  相似文献

Properties can be bought by government agencies, land trusts, or private entities for conservation and preservation purposes, such as farmland preservation, wildlife refuges, other conservation, and cultural and historical preservation. There is variation in the dollars paid per acre across properties and across buyer type. An option value model based on future potential land uses is used to explain much of this variation. The data used in our analysis is sales transactions data for conservation and preservation purposes from throughout the United States. We find that much of the value of conservation properties is derived from future potential land uses, including housing, timber, recreation, and conservation. We confirm that public versus private buyers value options differently, which makes sense from a public good point of view, if markets are thin.  相似文献
