Equilibria in the spatial stochastic model of voting with party activists

Stochastic models of elections typically indicate that all parties, in equilibrium, will adopt positions at the electoral center. Empirical analyses discussed in this paper suggest that convergence of this kind is rarely observed. Here we examine a stochastic electoral model where parties differ in their valences – the electorally perceived, non-policy “quality” of the party leader. It is assumed that valence may either be exogenous, in the sense of being an intrinsic characteristic of the leader, or may be due to the contributions of party activists, who donate time and money and thus enhance electoral support for the party. Theorem 1 shows that vote maximization depends on balancing these two opposed effects. Theorem 2 provides the necessary and sufficient conditions for convergence to the electoral mean when activist valence is zero. The paper then examines empirical electoral models for the Netherlands circa 1980 and Britain in 1979, 1992 and 1997 and shows that party divergence from the electoral mean cannot be accounted for by exogenous valence alone. The balance condition suggests that the success of the Labour party in the election of 1997 can be attributed to a combination of high exogenous valence and pro-Europe activist support.     

Productivity Growth in the Western Hemisphere (1978–94): The Caribbean in Perspective

Productivity growth, technical efficiency change, and technological change were measured for a sample of 30 countries in the Western Hemisphere for the 1978–1994 period using the Malmquist index. The Caribbean compared unfavorably with North America and the Latin American regions. Evidence indicated some support for the convergence hypothesis. Regression analysis indicated that productivity growth in the Caribbean was positively associated with civil, economic, and political liberty.     

Statistical Discrimination and Efficiency

This paper asks whether statistical discrimination is a market failure. I consider the problem for a utilitarian social planner who operates in an environment that can generate statistical discrimination as an equilibrium phenomenon. It is found that there are potential efficiency gains from discrimination in terms of reduced "mismatch" between workers and jobs. Whether the solution to the planning problem involves discrimination depends on the trade-off between the informational gains of specialization and the losses in terms of increased investment costs.     

Registered nurses' perceptions of nursing

In Part II of this six part series on the state of the registered nurse (RN) workforce in the United States, the focus is on RNs' perceptions of nursing including RNs' satisfaction with their jobs in general and on specific elements of their work experiences, such as the quality of professional relationships. Satisfaction with a nursing career and whether RNs would recommend nursing to others are also examined. The improvements in nursing found in this analysis of two national surveys in 2002 and 2004 should be broadly communicated not only to energize individuals and organizations to continue their efforts to improve the workplace environment, but to challenge the many individuals in the nursing profession who hold onto a sense that nothing will ever improve in their organizations.     

Customer mind-set of employees throughout the organization

Previous research has provided strong evidence for the benefits of embracing a market orientation, an organizational focus highlighting the needs of customers, and the creation of customer value. This study extends this focus on the customer to the individual worker level. A construct, customer mind-set (CMS), is developed that reflects the extent to which an individual employee believes that understanding and satisfying customers, whether internal or external to the organization, is central to the proper execution of his or her job. In this exploratory study, the authors develop a parsimonious scale for measuring CMS. Relationships between CMS and significant organizational variables are examined to establish CMS's validity and provide some tentative insights into its value to researchers and practitioners. The authors believe the CMS construct will allow for operational-level analysis of the extent to which a customer orientation is embraced throughout an organization, permitting managers to implement targeted improvement strategies.

What causes violent crime?

This study uses panel data of intentional homicide and robbery rates for a sample of developed and developing countries for the period 1970-1994, based on information from the United Nations World Crime Surveys, to analyze the determinants of national crime rates both across countries and over time. A simple model of the incentives to commit crimes is proposed, which explicitly considers possible causes of the persistence of crime over time (criminal inertia). A panel-data based GMM methodology is used to estimate a dynamic model of national crime rates. This estimator controls for unobserved country-specific effects, the joint endogeneity of some of the explanatory variables, and the existence of some types of measurement errors afflicting the crime data. The results show that increases in income inequality raise crime rates, crime tends to be counter-cyclical, and criminal inertia is significant.

Multiple Criteria Decision Making: A Case Study of the Columbia River Salmon Recovery Plan

A common problem faced by decision makers is choosing the best alternative from among many. Traditionally, such decisions in the public arena were made using benefit-cost analysis, which involves the conversion of all costs and benefits associated with a project into monetary terms. But public projects often have a variety of economic, ecological, social and political objectives, many of which cannot or perhaps should not be converted to monetary terms. In such projects decisions must be made based on multiple, even conflicting objectives. Multiple criteria decision making (MCDM) methods are widely used for such decisions. However, a common disadvantage among many such methods available in the literature is that they require input from a real decision maker. This paper presents the development and application of an expert system based on fuzzy set theory and IF-THEN rules. The system mimics a real decision maker. Along with two conventional MCDM methods the developed expert system was applied on a data set from the Columbia River Basin salmon recovery plan to assess its potential usefulness as a decision-making tool for natural resource projects. The results suggest that the fuzzy expert system is easy to develop and makes better decisions than the other two conventional MCDM methods used.     

The Profitability of Momentum Investing

We test for the presence of momentum profits in the UK over the period 1977 to 1998. The analysis shows that significant momentum profits are present in both a comprehensive sample of UK stocks and an accounting sub-sample. An analysis of sub-period results, seasonal effects, and the persistence of momentum profits confirms the robustness of the results. Controlling for factors known to be associated with differences in average returns, such as size, stock price, book-to-market ratio, and cash earnings-to-price ratio, cannot explain momentum profits. We also confirm that serial correlation in common factors and delayed price reaction to common factor realisations cannot explain momentum profits. We conclude that the momentum effect derives from market underreaction to either industry- or firm-specific information and it is a significant, independent phenomenon in UK stock returns.     

Voluntary disclosure of operating income

This study investigates whether New Zealand firms’ voluntary disclosure of operating income, which is also known as earnings before interest and tax, in the income statement is related to the investment opportunity set. New Zealand provides an ideal setting to examine this because New Zealand generally accepted accounting principles do not require the disclosure of operating income as an intermediate income number in arriving at net income (earnings) in the income statement. We hypothesize and find evidence that firms with high assets‐in‐place and high leverage are more likely to voluntarily disclose operating income/earnings before interest and tax. However, the assets‐in‐place finding is sensitive to alternative measures of the investment opportunity set.
