Uncertainty Associated with Future Environmental Costs and the Market's Differential Response to Earnings Information

This study examines whether the uncertainty arising from a firm's exposure to future environmental costs (environmental uncertainty) affects the market's price sensitivity to reported earnings. Specifically, when environmental uncertainty is significantly high, are investors more responsive to reported earnings released by 'high-polluting' firms than reported earnings announced by 'low-polluting' firms within the same industry? The initial impact of Title IV (the acid rain provisions) of the 1990 Clean Air Act Amendments (1990 CAAA) on the US electric utility industry provides the research setting required to isolate the effects of environmental uncertainty while addressing this question. Consistent with theoretical predictions, we find that the earnings response coefficients (ERCs) of high-polluting electric utilities are significantly greater than those of their low-polluting counterparts during a predicted period of elevated environmental uncertainty. In adjoining sample years associated with lower environmental uncertainty, we observe no statistical difference in the magnitude of the ERCs between these two groups. In addition, the study's findings suggest that the magnitude of the ERC is increasing in the firm's exposure to future environmental costs, after controlling for other factors that potentially affect ERCs.     

How Issue Size, Risk, and Complexity are Influencing External Financing Costs: German IPOs Analyzed from an Economies of Scale Perspective

This paper is focused on the cost of raising capital in Germany. A cross-sectional analysis of flotation cost data for 117 IPOs over the years 1993–1998 is presented. We find average flotation costs to be 7.77 percent of gross proceeds, while underwriting fees average 5.01 percent. Our results extend the literature in two important directions. First, contrary to the conventional economies of scale view we find marginal spreads to be rather constant in gross proceeds and to be higher for more risky and more complex offerings. Fixed costs amount to 5 to 9 percent of underwriting fees. Second, by applying a principal component analysis we find issue size, an issuer risk factor, and an offering method complexity factor to have an economicaly meaningful impact on underwriting fees.     

The Impact of Regulation Fair Disclosure on Information Asymmetry and Trading: An Intraday Analysis

This study examines the impact of Regulation Fair Disclosure (FD) on liquidity, information asymmetry, and institutional and retail investors trading behavior. Our main findings suggest three conclusions. First, Regulation FD has been effective in improving liquidity and in decreasing the level of information asymmetry. Second, retail trading activity increases dramatically after earnings announcements but there is a significant decline in institutional trading surrounding earnings announcements, particularly in the pre‐announcement period. Last, the decline in information asymmetry around earnings announcements is closely associated with a lower participation rate in the pre‐announcement period and more active trading of retail investors after earnings releases.     

Whistle-Blowing for Profit: An Ethical Analysis of the Federal False Claims Act

This paper focuses on the 1986 Amendments to the False Claims Act of 1863, which offers whistle-blowers financial rewards for disclosing fraud committed against the U.S. government. This law provides an opportunity to examine underlying assumptions about the morality of whistle-blowing and to consider the merits of increased reliance on whistle-blowing to protect the public interest. The law seems open to a number of moral objections, most notably that it exerts a morally corrupting influence on whistle-blowers. We answer these objections and argue that the law is not objectionable on these grounds. Since there are no compelling moral objections to the law, it is appropriate and acceptable to judge the law in terms of its economic costs and benefits. We assess the most salient of these and conclude that the benefits outweigh the costs. We suggest that a mechanism similar to the Act should be considered for protecting stockholders’ interests in the private sector. We conclude by making several proposals for improving the existing legislation. The authors' names are listed in alphabetical order. An earlier version of this paper was presented to the Society for Business Ethics August 2004.     

经济成本核算问题探讨——以医院为例

我国现行的成本核算方法,经过十多年来的不断革新,为国民经济核算和宏观决策提供了大量的信息,起到了积极作用。但在有计划的商品经济体制的新形势下,仍很难适应经济发展和改革的需要,且日益暴露出种种弊端。因此,改进现行成本核算方法是当务之急。本文以医院成本核算为例,探讨了医院建立成本核算体系的措施以及注意的问题。     

In-hospital risk of venous thromboembolism and bleeding and associated costs for patients undergoing total hip or knee arthroplasty

Abstract

Objective:

Benefits of anti-coagulation for venous thromboembolism (VTE) prevention in total hip and knee arthroplasty (THA/TKA) may be offset by increased risk of bleeding. The aim was to assess in-hospital risk of VTE and bleeding after THA/TKA and quantify any increased costs.

Methods:

Healthcare claims from the Premier Perspective^TM Comparative Hospital Database (January 2000–September 2008) were selected for subjects ≥18 years with ≥1 diagnosis code for THA/TKA. VTE was defined as ≥1 code for deep vein thrombosis or pulmonary embolism. Bleeding was classified as major/non-major. Incremental in-hospital costs associated with VTE and bleeding were calculated as cost differences between inpatients with VTE or bleeding matched 1:1 with inpatients without VTE or bleeding.

Results:

A total of 820,197 inpatient stays were identified: 8042 had a VTE event and 7401 a bleeding event (2740 major bleeding). The risks of VTE, any bleeding, and major bleeding were 0.98, 0.90, and 0.33/100 inpatient stays, respectively. Mean incremental in-hospital costs per inpatient were $2663 for VTE, $2028 for bleeding, and $3198 for major bleeding.

Limitations:

These included possible inaccuracies or omissions in procedures, diagnoses, or costs of claims data; no information on the amount of blood transfused or decreases in the hemoglobin level to evaluate bleeding event severity; and potential biases due to the observational design of the study.

Conclusions:

In-hospital risk and incremental all-cause costs with THA/TKA were higher for VTE than for bleeding. Despite higher costs, major bleeding occurred less frequently than VTE, suggesting a favorable benefit/risk profile for VTE prophylaxis in THA/TKA.     

私利与公益的协调是可能的吗——斯蒂芬·杨“道德资本主义”经济伦理观解析

经济伦理学要追求私利与公益的和谐的、协调的统一。斯蒂芬.杨提出以道德资本主义的经济伦理观来有效协调两者的关系,对人们颇有启发。道德资本主义提倡将私利投入公益,践行者要有＂考虑整体的自我利益＂的意识。现实经济生活中有效地结合了私利与公益的成功企业,对于终结贫困的重大价值,道德资本主义本身所具有的最佳结合了超越性之理想与现实性之欲念的特点等为道德资本主义提供了可能性。考克斯原则是目前全球范围内践行道德资本主义的范例。但是,道德资本主义要真正落到实处还必须大力培养有原则的商业领导。

Gender, poverty and deprivation: Evidence from the Republic of Guinea

The article examines the relationship between gender and consumption poverty and between gender and deprivation in the Republic of Guinea. National household survey data reveal that women are not more likely than men to be consumption poor or to suffer greater consumption poverty. Participatory Poverty Assessment data from the village of Kamatiguia reveal that women are “worse off” than men when deprivation includes, inter alia, excessive work load and reduced decision-making authority. When consumption poverty poorly correlates with other dimensions of deprivation, it should not be the sole guide for equity-based policy intervention.
