Buchanan and Tullok (The calculus of consent: logical foundations of constitutional democracy. University of Michigan Press, Ann Arbor, 1962) argued that the optimal k-majority rule should minimize the sum of external costs and decision costs. Dougherty et al. (Public Choice, 163(1–2):31–52, 2015) formalized their approach using various groups of voters. In this study, we analyze the optimal k-majority rule in terms of expected utility and compare our results to Dougherty et al. (2015), which focuses on costs alone. Specifically, we replace Buchanan and Tullock’s external cost function with an external utility function that accounts for both the benefits and costs of enacting proposals. We find that analyzing k-majority rules in terms of utility, rather than costs, affects the optima. Furthermore, in terms of utility, the optimal k-majority rule can vary depending on the group one expects to be in during a vote. With some interesting exceptions, individuals from groups that favor the proposal often find small k-majority rules optimal. Individuals from groups that oppose the proposal often find large k-majority rules optimal.  相似文献

While much has been written on the racial gap in achievement, few national studies have assessed the gap’s trajectory over K-12 schooling. The reason for this is understandable—most national data sets do not contain respondent information for this entire educational period. I utilize survey data from three national data sets containing White and Black students to document the trajectory of reading and math inequality between school entry and the end of high school. An attempt to clarify these observed patterns is made by assessing changes in the score distributions of these students across grade level, and examining how Black score distributions would fare if held to the White score distributions. Findings suggest that efforts to equalize achievement disparities must not only focus on “bringing the bottom up”, but also on keeping the top Black achievers on pace with the top White achievers across grade level.  相似文献

This study investigates the judgments made by accounting majors when confronted with selected ethical dilemmas that pertain to accounting practice. Drawing upon literature in philosophy and moral psychology, it then examines these judgments for potential gender differences. Five case studies, each involving a specific ethical dilemma that a practicing accountant might face, were administered to 151 acounting majors (males = 67; females = 84), in four sections of intermediate accounting II at a large, state university. The results suggest that although the vast majority of participants wouldnot engage in unethical behavior, a reasonable opportunity exists to improve the participants' ethical awareness. The results do not, however, support the existence of gender differences in ethical judgments. Keith G. Stanga is Distinguished Professor of Accounting at the University of Tennessee, Knoxville. His most recent publications include a book, Intermediate Accounting(3rd edition, Harcourt Brace Jovanovich, 1989, 1486 pp.), and articles published in the Journal of Accountancy, Accounting and Business Research, Accounting Horizons,and Advances in Accounting.Professor Stanga's teaching and research interests are in financial accounting. His most recent research topics have included the relevance of segment cash flow reporting, the Financial Accounting Standards Board's conceptual framework, and the last-in, first-out method of inventory costing. Richard A. Turpen is an Assistant Professor at The University of Tennessee, Knoxville. His primary teaching interest is in financial accounting, while his research focuses mainly on competitive issues in the market for audit services. Professor Turpen has published most recently in Auditing: A Journal of Practice & Theory.  相似文献

ABSTRACT

Potential biofuel demand in South Africa is estimated to increase to 1550 million litres by 2025 due to mandatory blending rates. Land and water constraints, however, limit the ability for domestic production. Zambia, due to its abundance in land, suitable climate, supportive set of bioenergy incentives and close geographical location to South Africa, has the potential to meet this increase in demand. Using a dynamic recursive computable general equilibrium model, we estimate the macro- and socio-economic impacts of bioethanol production in Zambia from three potential crops: sugarcane, cassava and sweet sorghum. The results show that the development of a single product bioethanol industry has the potential to increase economic growth without negatively affecting overall food security. Further expansion of the industry to multiple products results in larger gains to growth and welfare.  相似文献

An empirical study involving 97 manufacturing firms that averaged $20 million in annual sales yielded a strong positive correlation between the degree of planning formality and firm performance. Additionally, interactive analysis disclosed that this relationship pervaded various grand strategies; the implication being that formalized strategic planning was consistently a positive factor associated with high levels of organizational performance.  相似文献

This article examines HRM in joint ventures (JVs) in Shanghai compared with those in Beijing using a case-study approach. It focuses primarily on issues relating to labour contracts, rewards and benefits, social insurance, trade unions and personnel policies, and describes current developments in China in each of these areas. In order to place these JV human resource practices in context, we also draw on interviews in state-owned enterprises (SOEs) in Shanghai and Beijing. Taking as a starting point a summary of traditional SOE 'iron rice-bowl' ( tie fan wan ) practices in the management of personnel, we ask to what extent HRM in the present JV sample differs from traditional methods and to what extent 'iron rice-bowl' practices continue despite foreign ownership. The extent to which HR practices in JVs are distinct from those in contemporary SOEs is also examined. We conclude that, although, as one would expect, foreign ownership has modified traditional practice, the degree and extent to which this is true varies widely. There is strong evidence of institutional and organizational continuity in 'iron rice-bowl' practices in both JVs and SOEs. Finally we propose a framework for categorizing the companies investigated in terms of their distance from traditional 'iron rice-bowl' HR practices and proximity to 'imported' practices. This consists of two 'pure' and two hybrid categories: pure 'iron rice-bowl'; hybrid I (predominantly local); hybrid II (predominantly imported): and, finally, pure imported. In this schema, the companies examined do not however group neatly according to whether they are JVs or SOEs.  相似文献

Human players in our laboratory experiment received flow payoffs over 120 seconds each period from a standard Hawk–Dove bimatrix game played in continuous time. Play converged closely to the symmetric mixed Nash equilibrium under a one-population matching protocol. When the same players were matched in a two-population protocol with the same bimatrix, they showed clear movement towards an asymmetric (and very inequitable) pure Nash equilibrium of the game. These findings support distinctive predictions of evolutionary game theory.  相似文献

Data on R & D expenditures and US patenting in the world's 660 largest, technologically active firms both show a linear relation between firm size and the volume of innovative activities, despite some inconsistencies between the two measures. Technological diversity increases with firm size, but relatively weakly, especially in R & D-intensive sectors. Sectoral variations in the comparative technological advantage of large firms based in Japan, the USA and W. Europe are better explained by variations in rivalry in their home market than by variations in their size.  相似文献
