Abstract. This paper explores the extent to which majority rule is invulnerable to manipulation by individuals and coalitions, even
when majority rule is used to select more than one alternative. The resulting rule may or may not be strategy-proof, depending
on the size of the coalitions that can form, and on the nature of the individual preferences over sets of alternatives. No
individual can manipulate with respect to a wide family of preferences over sets. The only restriction on the domain of true and revealed
individual preferences is that the selection rule is always well defined.

This study, using data collected from 325 Irish white-collar employees in the private sector, examines the extent to which white-collar trade unionism may be regarded as a response to concern about the lack of achievement of desired levels of self-expression at work. 相似文献

Price and quantity regulation in general equilibrium 总被引:1,自引:0,他引:1
David L. Kelly 《Journal of Economic Theory》2005,125(1):36-60
We consider a general equilibrium model with a production externality (e.g. pollution), where the regulator does not observe firm productivity shocks. We examine quantity (permit) regulation and price (tax) regulation. The quantity of permits issued by the regulator are independent of the productivity shock, since shocks are unobserved. Price regulation implies use of the regulated input is an increasing function of the productivity shock because firms take advantage of a good productivity shock by increasing input use. Thus price regulation generates higher average, but more variable, production. Therefore, we show that in general equilibrium the relative advantage of quantity versus price regulation depends not only on the slopes of marginal benefits and costs, but on general equilibrium effects such as risk aversion. The general equilibrium effects are often more important than the slopes of the marginal benefits and cost curves. In the simplest model, a reasonable risk aversion coefficient implies quantity regulation generates higher welfare regardless of the benefit function. 相似文献

Dysfunctional nurse-physician communication has been linked to medication errors, patient injuries, and patient deaths. The organization is accountable for providing a context that supports effective nurse-physician communication. Organizational strategies to create such a context are synthesized from the structural, human resource, political, and cultural frameworks of organizational behavior. 相似文献

Summary An Arrovian social choice rule is a social welfare function satisfying independence of irrelevant alternatives and transitivity of social preference. Assume a measurable outcome spaceX with its (Lebesgue) measure normalized to unity. For any Arrovian rule and any fractiont, either some individual dictates over a subset ofX of measuret or more, or at least a fraction 1–t of the pairs of distinct alternatives have their social ordering fixed independently of individual preferences. Also, for any positive integer (less than the total number of individuals), there is some subsetH of society consisting of all but persons such that the fraction of outcome pairs (x, y) that are social ranked without consulting the preferences of anyone inH, whenever no individual is indifferent betweenx andy, is at least 1–1/4.We are grateful to Roy Mathias and Daniel Waterman for help with some technical matters, and to chairman Jim Follain and the Syracuse University Economics Department for financing the exchange that launched this project.

This paper describes and evaluates the Federal Reserve System's recently developed program designed to use HMDA data as a screening device for fair lending enforcement. The program is designed to identify institutions showing potentially discriminatory patterns in their treatment of minority mortgage applicants vis-a`-vis nonminority applicants. The program also selects specific loan files to pull for additional information in cases where a more comprehensive evaluation might be appropriate. This paper discusses the motivation behind the adoption of the program and its innovative matched-pair method and assesses its value and potential shortcomings. 相似文献

This paper proposes an approach to the intraday analysis of diversified world stock accumulation indices. The growth optimal portfolio (GOP) is used as reference unit or benchmark in a continuous financial market model. Diversified portfolios, covering the world stock market, are constructed and shown to approximate the GOP, providing the basis for a range of financial applications. The normalized GOP is modeled as a time transformed square root process of dimension four. Its dynamics are empirically verified for several world stock indices. Furthermore, the evolution of the transformed time is modeled as the integral over a rapidly evolving mean-reverting market activity process with deterministic volatility. The empirical findings suggest a rather simple and robust model for a world stock index that reflects the historical evolution, by using only a few readily observable parameters.

The persistence of earnings and cash flows and the role of special items: Implications for the accrual anomaly 总被引:2,自引:0,他引:2
We argue that high accruals are likely to be the outcome of rules with an income statement perspective, while low accruals are likely to be the outcome of rules with a balance sheet perspective, and that this has implications for the properties of earnings. Specifically, earnings persistence is affected both by the magnitude and sign of the accruals. Accruals improve the persistence of earnings relative to cash flows in high accrual firms, but reduce earnings persistence in low accrual firms. We show that the low persistence of earnings in low accrual firms is primarily driven by special items. We then show that special item-low accrual firms have higher future stock returns than other low accrual firms. This is consistent with investors misunderstanding the transitory nature of special items. Further analysis reveals that special item-low accrual firms have poor past performance and declines in investor recognition (analyst coverage and institutional holdings). Special items continue to explain future returns after controlling for these factors. 相似文献
