Manipulating uncertainty   总被引:1,自引:1,他引:0  
Uncertainty about the distributional incidence of policy reforms may, if it impinges selectively on particular subsets of voters, alter the direction of the majority vote. This possibility should be a matter of special concern when subject to potential manipulation by a purposeful agent such as a Leviathan-like bureaucracy. This paper discusses a constitutional defense against such prospect. This paper was prepared for a conference on “Constitutional Status Quo and Prospects for Change” held at George Mason University in April, 1994. I am grateful to participants in that conference and to my colleagues at Nova, especially to Mário Páscoa, for their comments and criticisms. I also benefited from comments of an anonymous referee. Responsibility for errors remains with me.  相似文献

The notion that prices impound a wide array of information, including market expectations, has led to earnings forecast models conditioned on prices. Yet, presumably, analysts' forecasts capture both public information and certain private information not previously impounded in prices. Accordingly, price-based models are seemingly an inefficient, and less effective, source of expecta-tions. This article investigates this hypothesis using financial analysts', price-based, and naive forecasts. Results indicate that analysts' forecasts (1) are at least as accurate as price-based and naive models, and (2) yield better expectations for market tests relating returns and earnings. These inferences are robust across different information environments. The evidence suggests that analysts either possess private information or are more effective information processors, or both.  相似文献

External technology acquisition in large multi-technology corporations   总被引:7,自引:0,他引:7  
Based on different contractual forms and their associated degrees of organizational integration, a typology of strategies for technology acquisition (sourcing) is constructed. Based on a sample of corporations in Europe, Japan and US, it is shown that external acquisition of technology through various strategies increases in importance in general. Product case studies further show that external acquisition of technology is associated with technology diversification into increasingly costly new technologies. As a result corporations become multi-technological ('multech'). At the same time quasi-integrated corporate systems of innovation arise in which in-house R&D is managed together with a mix of strategies for external acquisition of technology, using various contractual forms. This presents new challenges to traditional in-house R&D management. Technology diversification is moreover shown to be associated with growth of sales as well as with growth of R&D expenditures. A high level of external technology acquisition presents risks that ought to lead companies to consider technology based product diversification.  相似文献

The recent revival of interest in the issue of limiting auditors' liability raises questions about the potential effect of such a limitation on auditors' performance. This paper considers the consequences of limited liability from the perspectives of contracting theory and economic arguments. We examine the potential effect of a reduction in auditors' liability on the standard of care or quality of service they provide, emphasising the "calculus of negligence" concept used by Australian courts. We consider the potential impact of reduced liability on the auditor's decision to shirk responsibilities (the moral hazard problem) and on the value placed on audit services. The analysis shows that placing a statutory cap on auditors' liability has the potential to reduce the effectiveness of bonding mechanisms; provide an avenue for divergent behaviour; lower the level of care provided by auditors; and decrease the value of audit services.  相似文献

This paper highlights the difficulty of developing HT firms in a peripheral region of Spain. Although the endogenous development of HT firms in these regions is possible, their evolution depends on more central regions. The firm's geographical location and the type of HT production are the most important endogenous factors governing the firm's success.  相似文献

The ongoing conversion of the economies of former socialist countries into market economies has so far suffered from the lack of a theory of system transformation (policy) which indicates the means of achieving the desired objectives and makes it possible to evaluate the transformation policies of individual countries. The following article outlines the essential aspects of such a theory.  相似文献
