This paper examines the determinants of intended electoral participation. We analyze attitudes to both referenda and voting in national elections. Sample survey data are obtained from the Eurobarometer survey of transition countries in Central and Eastern Europe. The empirical results suggest that intended electoral participation increases with age, income and education. But attitudinal variables are also important and in particular confidence in the free market economy and satisfaction with the general development of the country impact positively on intended electoral participation.

We are also grateful for the helpful comments of three anonymous referees, the journal editor and R. Filer and L. Squires.  相似文献

The Worker Adjustment and Retraining Notification (WARN) Act of 1989 mandated that at least 60 days advance notice be given to employees. Critics argued that its passage would decrease managerial flexibility in closing plants, subsequently reducing firm values. This study addresses this issue by examining the stock market's reaction to announcements leading to the eventual enactment of the WARN legislation. We find evidence indicating negative effects of the legislation on stock returns of small firms.  相似文献

This paper develops a rational expectations framework for interpreting the coefficient on age in a standard hedonic model. The model demonstrates that there are two components to the age coefficient: a pure cross-sectional depreciation component and a demand-side component that changes over time. We also show that a constant quality price index with age constant can be estimated by using any repeat sales database that contains the year of construction (or property age). When Fairfax County data are fitted to the model, the time series of age coefficients is non-stationary: they change from negative in the early 1980s to positive in the late 1980s; we infer that the demand-side component dominated in the latter period.  相似文献

The underlying “architecture of the decision to pursue a degree in psychology was quantified using the Method of Sorting technique to identifying the critical issues necessary to make this choice. Multidimentsional scaling procedures were employed to construct a three-dimensional map representing the relationships between reasons for selecting psychology as a major. Freshman and senior psychology majors (N = 165) from a regional university and a large research-based institution rated the relative importance of items in their decision-making process. Hierarchical clustering procedures revealed seven different groups of students. Although significant differences associated with class standing were not found, institutional affiliation did influence cluster composition. Reflecting local emphases, students at the regional institution had a greater interest in Counseling Psychology, whereas those at the research-based school focused on Clinical Psychology. This semantic map and the associated item clusters arising from psychology student data provides an empirical basis for, amongst other things, course selection, faculty-initiated program design or revision, strategic niche marketing, and student retention.  相似文献

STRATEGIC INVESTMENT DECISION-MAKING: COMPLEXITIES, POLITICS AND PROCESSES*   总被引:1,自引:0,他引:1  
This article is a preliminary report on an investigation into the processes of investment decision-making. Three case studies from three firms are presented which show disparities in a number of aspects of process, for example, the length of time taken to arrive at a decision, the number and intensity of disagreements and uncertainties encountered. Data were collected for these cases through semi-structured interviewing from multiple informants in the three organizations, thereby permitting the use of analysis of variance techniques of the different perspectives given by informants. Perceptions of the effectiveness of the decisions were also gathered. One finding from the study is that the decisions with the lowest perceived effectiveness (in firm HE) also lost support from those involved in making the decision during the process, although the decision was eventually implemented. This decision also had the least agreement amongst informants as to the main sources of disagreements. Informants of all three decisions saw effect upon product quality and productivity, fit with business strategy and competitive position of the company as the most important factors to take into account in evaluating the decisions. In firm CG, however, there were disagreements as to how the investment should be evaluated. In the conclusions to the article a disucssion is given as to the nature of evaluation procedures in relation to the developing theory of information systems.  相似文献

A bstract . A number of lake restoration demonstraton projects have been launched by the Environmental Protection Agency as a result of Public Law 92-500. To evaluate the cost-effectiveness of these public investment projects requires the development of an assessment model. The proposed Benefit/Cost Cross-Impact Probabilistic Approach (BCCIPA) is one attempt at assessing the interdependent socioeconomic and environmental impacts of the lake restoration project over time, both quantitatively and qualitatively, so that various changes brought about by the project can be investigated and evaluated in two comparative stages for three points in time—before, during and after project implementation.  相似文献

THEORIES OF CHOICE UNDER IGNORANCE AND UNCERTAINTY   总被引:1,自引:0,他引:1  
Abstract. In this paper, Knight's distinction between risk and uncertainty, and its significance for economic analysis are examined. The paper consists of a survey of some recent developments on the theory of choice under uncertainty and some applications of these theories to problems for which Bayesian Decision Theory has not proved entirely satisfactory. Two problems are examined in detail. The first is that of finance and insurance and the second is that of risktaking behaviour with special emphasis on lotteries.  相似文献

abstract    Studies on the three types of process improvement programmes (Continuous Improvement, Reengineering and Benchmarking) have appeared many times in the literature. These studies suggest that certain organizational variables act as enablers and their presence or absence can significantly influence success rates. Such studies have tended to examine companies where a single programme has been implemented. In contrast, this paper examines a sample of companies who have experienced all three programmes. Our aim is to compare and contrast each programme's impact on firm performance and identify which organizational variables are common and which are programme-specific enablers of success. We build and test an integrative framework to support our analysis. Our study found that: (1) Reengineering delivered the greatest impact on performance; (2) executive commitment was needed to make this happen; (3) strategic alignment was the major influence on the success rate of Reengineering and Continuous Improvement programmes; and (4) employee empowerment was necessary for each programme to work effectively.  相似文献
