Investigations into ethical judgments generally seem fuzzy as to the relevant research domain. We first attempted to clarify the construct and determine domain parameters. This attempt required addressing difficulties associated with pinpointing relevant literature, most notably the varied nomenclature used to refer to ethical judgments (individual evaluations of actions’ ethicality). Given this variation in construct nomenclature and the difficulties it presented in identifying pertinent focal studies, we elected to focus on research that cited papers featuring prominent and often-used measures of ethical judgments (primarily, but not exclusively, the Multidimensional Ethics Scale). Our review of these studies indicated a preponderance of inferences and conclusions unwarranted by empirical evidence (likely attributable at least partly to inconsistent nomenclature). Moreover, ethical judgments related consistently to few respondent characteristics or any other variables, emergent relationships may not always be especially meaningful, and much research seems inclined to repetition of already verified findings. Although we concluded that knowledge about ethical judgments seems not to have advanced appreciably after decades of investigation, we suggested a possible path forward that focuses on the content of what is actually being judged as reflected in the myriad of vignettes used in the literature to elicit judgments.  相似文献

Informed by social exchange theory and social identity theory, we developed a conceptual model that examines the mediating role of organizational identification in the relationship between employees’ perceptions of organizational context and their job attitudes. In our model, the antecedents include perceived organizational support (POS), procedural justice, and perceived job insecurity. The outcome variables consist of affective organizational commitment, job satisfaction, and intentions to leave. Our respondents were 591 workers employed in three different firms in China. The results of regression analyses showed that employees’ job attitudes are affected by their perceptions of organizational context and organizational identification. Further, organizational identification was found to mediate the effects of POS on the outcome variables.  相似文献

With the proliferation of alternative markets, concerns have arisen that they may induce lower liquidity on centralized exchanges. In futures markets, the use of an alternative trading mechanism known as exchange of futures for physicals (EFPs) has increased sharply in recent years. EFPs provide a means to obtain futures positions, coupled with offsetting cash positions, away from the centralized exchange. Traders use EFPs to ensure a desired price on complex packages of trades, thus avoiding the transactional risk (slippage) that is inherent in the centralized market. Theoretical analysis establishes that any detrimental effects of fragmenting the centralized market can be offset by traders' knowledge of another opportunity to trade without transactional risk. If EFPs attract more risk‐bearing capacity, there could even be a net benefit to the central market. An empirical analysis suggests that EFP trading is motivated by transactional risk because it represents a larger portion of total trading during periods of unusually high volatility when slippage is apt to be more of a problem. Consistent with the notion that alternative markets can be complementary to centralized exchanges, we find that EFP trading is not associated with reductions in market quality and may act as an outlet for extra volume when markets are under the most stress. © 2002 Wiley Periodicals, Inc.

In practice, infrastructure planning has generally tended to follow land-use planning, with infrastructure costs seeming to play no role in the generation of land-use strategies. To address this problem, a bulk infrastructure cost model has been developed to provide a tool for planners to ensure the incorporation of bulk infrastructure capacity and cost considerations into the early, land suitability assessment phase of the integrated development planning process. The output of the model is in the form of potential cost contours, which facilitates the relative comparison of infrastructure costs for different density scenarios. Bulk engineering services infrastructure relating to water, sanitation and electricity has been included in the model. The theoretical underpinning of the model is threshold analysis, and the three essential elements are threshold, density and cost. They are incorporated into the model through capacity analysis. The set density levels convert into the number of additional person units required which, in turn, is translated into infrastructure capacity demand. Existing infrastructure network and facility design capacities are compared with the current utilisation of infrastructure in order to quantify the capacity supply situation. The comparison of capacity demand with capacity supply determines whether or not additional infrastructure is required. If infrastructure is required, the required infrastructure investment is calculated. The resulting relative costs are mapped and incorporated into a wider land suitability assessment model. Infrastructure costs vary with location according to local land use, geotechnical, environmental and built conditions, making the role of the geographic information system in the model appropriate and important.  相似文献

Democratisation has fundamentally changed the formal institutional structure of Indonesian politics, but a wealth of contemporary research has demonstrated that the informal mechanisms of power and influence have survived the transition. This article uses a unique, hand-collected dataset of information on Indonesian public figures to empirically catalogue the changes and continuities in Indonesian politics since democratisation. Our results provide quantitative evidence of a substantial shift in Indonesia’s political economy over the last decade and a half: the simultaneous rise of the private sector and decline of the military and the state as avenues to political influence at the national level. Our evidence also suggests that the origins of this shift pre-date democratisation itself.  相似文献

Research summary : Using a large sample of private firms across Europe, we examine how the social context of owners affects firm strategy and performance. Drawing on embeddedness theory and the institutional logics perspective, we argue that embeddedness in a family, in particular the nuclear family, can strengthen identification and commitment to the firm, but can also induce owners to behave more conservatively. Consistent with this argument, we find that family‐owned firms have higher profit margins, returns on assets, and survival rates compared to single‐owner or unrelated‐owners' firms, but also invest and grow more slowly, hold greater reserves of cash, and rely less on external debt. These differences are most pronounced when the two largest shareholders are married. Our results highlight the key role of marital ties in explaining differences in behavior and performance among firms. Managerial summary : Despite the prevalence of the married‐couple ownership structure in firms, little research has been dedicated to understanding how these firms are managed and perform. We examine the behavior and performance of firms owned by married couples in a large panel of closely held Western European firms. We find that married‐owner family firms are managed more conservatively relative to firms with unrelated owners and even to other family‐owned firms. In particular, married‐owner family firms invest and grow more slowly and rely less on external finance. However, they also exhibit greater performance stability and higher profitability. Our findings suggest that social relationships among owners have a large impact on firm strategy and performance, and highlight some potential trade‐offs to performance when married couples control firms.

Research summary: This paper uses signaling theory to bring together two complementary research streams that have largely ignored each other: strategic human resource management and media relations management. We argue that when publicly traded firms voluntarily and publicly disclose positive information about their value creation and appropriation activities, they also send positive signals to managerial labor markets regarding executives' capabilities. Accordingly, we hypothesize a positive association between public disclosures and voluntary executive turnover. An analysis of pharmaceutical and communications equipment firms from 1990 to 2004 supports this prediction, underscoring the need to understand better the effects of voluntary public disclosures on a firm's ability to protect its human capital. More generally, our results highlight the importance of considering the impact of a single signal on multiple receivers. Managerial summary: Given the organizational benefits of positive media coverage, the considerable effort that firms put into managing their image in the media is not surprising. We argue and show, however, that when a firm enhances its public image it also improves its executives' positions in the managerial labor market and, by so doing, increases their likelihood of voluntarily leaving the firm. In particular, we find that corporate press releases, an important mechanism for managing information released in the public domain to signal a firm's competitive advantages, may result in unintentional loss of senior management talent. This trade‐off suggests that firms should increase coordination between their strategy, human resources, and corporate communications/investor relations departments to ensure that they collectively weigh the benefits and costs of publicly disclosing value‐relevant information.

Research summary : We show that frictions in labor and capital markets can be a source of competitive advantage for affiliates of corporate groups over stand‐alone firms in environments where benefits from internal markets' flexibility are high. We argue that the advantage of flexibility in changing labor inputs is related to how difficult it is to change capital inputs. We predict that if substituting labor with capital is difficult, the group advantage of flexibly changing labor would be stronger in countries with high levels of financial development. Consistent with this prediction, we find a stronger competitive advantage for group affiliates in countries with rigid labor markets but flexible capital markets. In these environments, group affiliates are more prevalent and outperform stand‐alone firms in terms of growth and profitability. Managerial summary : This research shows that the capacity to redeploy workers across internal units of the firm can be a source of competitive advantage in countries that impose strict employment protection laws. We show that the strategic advantage of labor flexibility is affected by how difficult it is to change capital inputs and that labor flexibility is a stronger source of competitive advantage in countries where developed financial markets allow for more flexible capital adjustment. In these settings, strategies designed to lower costs of internal mobility (e.g., locations of greater geographic concentration between units and in regions with less competitive external markets), development of corporate culture supportive of frequent change, and personnel development through internal rotation can result in substantial financial payoffs.

For managers of managed health care organizations, the problem of designing a competitive multiple facility network cannot be solved by existing mathematical models. This paper thus presents a nonlinear integer model for determining a facilities design strategy that embodies the economic tradeoffs encompassed in a competitive strategy: minimizing cost and maximizing market share. The integrated location and service mix model determines the number, location and service offerings of facilities that maximize profitability in a two-level hierarchical referral delivery network where an organization's market share is represented by a multiplicative competitive interaction model. To demonstrate the usefulness of the proposed integrated model, a series of problems is solved by an interchange heuristic and compared to the solutions derived by a simpler approach that ignores market competition.  相似文献
