We examine the association between abnormal returns and earnings management in the context of price control regulations to test the construct validity of the earnings management model. Abnormal returns are used as a market–based measure, and discretionary accruals are employed to measure earnings management. Our results support the hypotheses that (1) price control regulations affect firms' security prices negatively, (2) firms make income–decreasing discretionary accruals to increase the likelihood of price increase approval, and (3) firms that are affected most negatively by the regulations manage earnings more aggressively. We conclude that the earnings management model we use in this study is capable of predicting opportunistic discretionary accruals. 相似文献

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. 相似文献

Abstract: We explore to what extent firms deliberately manage their financial reports by exploiting the flexibility of generally accepted accounting principles. Using a sample of Oslo Stock Exchange-listed firms with 20–50% equity holdings in other firms, we find that firms with high financial leverage tend to maximize reported earnings from these investments through their choice between the cost method and the equity method, possibly in an attempt to reduce debt renegotiation costs or to avoid regulatory attention. In contrast, managers do not systematically bias reported earnings to extract private benefits or to signal revised expectations about future cash flows. Firms use different earnings management tools in a consistent way, as the earnings effect of the cost/equity choice is not offset by discretionary accruals. 相似文献

复杂性管理的策略首先要关注和认识复杂系统的整体性,这要通过关注系统的结构、多元化的视角、容忍模糊性和不确定性、借助直觉等手段来达到。在关注和认识整体性的基础上,需要进一步维护和促进复杂系统的整体性,这需要通过保护系统的自组织、创造自组织环境条件、发现和维护序参量、鼓励多元化以及与环境相协调来达成。 相似文献

当前,我国政府绩效管理中存在的问题,主要是政府绩效管理缺乏统一的政策指导和制度保障,对政府缋效管理的理论研究与实践发展滞后,社会参与机制不完善,激励制度匮乏等。我国应通过立法来推进政府绩效管理的制度化和规范化;学习和借鉴西方先进思想,加强政府绩效管理的理论研究,建立有效的绩效评估指标体系和完善的激励制度。从而提高我国政府效能。增强政府管理能力。 相似文献

Summary. This research studies the role of multivariate distribution structures on random asset returns in determining the optimal
allocation vector for an expected utility maximizer. All our conclusions pertain for the set of risk averters. By carefully
disturbing symmetry in the distribution of the, possibly covarying, returns, we ascertain the ordinal structure of the optimized
allocation vector. Rank order of allocations is also established when a permutation symmetric random vector is mapped into
the returns vector through location and scale shifts. It is shown that increased dispersion in the vectors of location and
scale parameters benefit, ex-ante, investors as does a decrease in the rank correlation coefficient between the location and
scale parameter vectors. Revealed preference comparative static results are identified for the location and scale vectors
of asset returns. For most issues addressed, we arrive at much stronger inferences when a safe asset is available.

The purpose of this study was to (a) compare the occupational sex stereotypes of 366 college students with those reported by Shinar in 1975, and (b) examine the relationships between demographic, experiential, and attitudinal variables and these occupational sex stereotypes. The results indicated a significant difference in occupational ratings from Shinar's study, with females' perceptions shifting more than males' perceptions. In addition, subjects' gender, tenure with female managers, and attitudes toward women as managers, were shown to be significant predictors of occuptational ratings. The implications of these findings for both employees and managers are then discussed. 相似文献

The framework offered in this study provides empirical evidence concerning the interaction between distributive, procedural and interactional perceived justice and loyalty program satisfaction on relational satisfaction in the mobile telecommunication context. Firms that rely on justice perception for strategy implementation are able to attain customer retention. This study suggests a theoretical model of customer retention that aims at investigating the role of satisfaction with loyalty program on relationship marketing. The structural equation modeling was used to test the hypothetical relationships. A self-administrated questionnaire was distributed to a total of a convenience sample of 520 customers of multiple mobile phone companies. The target population includes customers who have subscribed to a loyalty program. Results show that distributive justice moderates the relationship between satisfaction with the loyalty program and relational satisfaction. The results highlight the need to focus on distributive justice in order to nurture satisfaction and loyalty. Satisfaction with the loyalty program is a key predictor of a satisfactory relationship with the operator and customer retention. 相似文献

Business uncertainty due to the COVID-19 pandemic has brought financial and banking industries under stress. This study examines brand loyalty (BL) in the Thai banking industry by integrating community relationship management (CoRM) (4Cs model), relationship marketing orientation (RMO), customer engagement (CE), and brand trust (BT). It analyzes how a Thai commercial bank used four success factors to create new client acquisition, business efficiency, long-term relationships, and BL. We use quantitative data and structural equation modeling (SEM) to identify variables influencing the BL of 1650 customers of a Thai commercial bank. We found CoRM and RMO's key success factors indirectly affected BL by mediating CE and BT. These results may improve sustained performance effectiveness in the banking industry now and in the future. 相似文献
