Organizational members frequently evaluate how their abilities and standing compare with those of their colleagues. Although these comparisons can have a negative impact on organizations, little attention has been paid to the role of leaders in these processes. Drawing on interviews with individuals in leadership positions in business schools, we develop a framework to explain what triggers leaders’ attention to social comparisons among faculty and how they become involved in them. Central to this framework are leaders’ self‐schemas, which encompass their preferences about the criteria members should use in making comparisons. Leaders’ self‐schemas are activated by discrepancies between their own comparative judgements and those they perceive members to be making and impel them to act in ways consistent with their preferred bases of comparison. Our framework repositions social comparisons as a multi‐perspectival, political phenomenon in which leaders see themselves as playing a role in shaping members’ evaluations and workplace interactions.  相似文献

This paper examines how two prominent corporate governance models, namely the shareholder and stakeholder models, have different effects on the relation between agency conflicts and the supply, and demand of audit services. Shareholder (stakeholder) countries rely heavily on public (private) information to reduce information asymmetry for outside investors in the context of high (low) litigation risk. We expect audit fees to reflect the level of agency conflicts in shareholder countries as well as the needs for information of the major blockholders in stakeholder countries. Using a sample of 7982 firm-year observations from 19 countries, we find a U-shaped relation between controlling shareholding and audit fees for shareholder countries and an inverted U-shaped relation between controlling shareholding and audit fees for stakeholder countries. These results are consistent across different firm-level governance arrangements.  相似文献

Using data from NLSS III, we estimate nutrient‐income elasticities for macronutrients, vitamins, and minerals. We further allow for differential nutrient demand response to income depending on where a household is in the caloric availability distribution. We find that some nutrients are income inelastic indicating that they are necessity goods while others are relatively income elastic. We further test and reject equivalent nutrient‐income elasticities across the caloric availability distribution. Households in the lowest calorie quintile have highly income elastic nutrient demand leaving them vulnerable to income fluctuations. Moreover, as households meet their first‐order caloric needs, they substitute away from cheap calorie‐dense staples toward more expensive nutrient‐dense foods. Finally, for most nutrients, households in the highest calorie quintile exhibit more elastic nutrient demand, similar to households in the lowest quintile. Our results suggest that policies aimed at improving income will likely also improve household nutrient availability, particularly for the most calorie poor households. They further suggest that policies aimed at protecting poor households from negative income shocks will also likely yield nutritional benefits.  相似文献

This study draws on the social cognitive theory to examine the effect of perceived market competition on employees’ unethical marketing and selling practices. The boundary conditions associated with this relationship were examined, and we posit that perceived market competition is related to unethical marketing and selling practices through the mediating mechanism of moral disengagement. We further propose that ethical leadership moderates the relationship between the perceived threat of market competition, moral disengagement, and tendency toward unethical marketing and selling practices. We tested our hypotheses with a sample of 387 employees working in the banking sector in Pakistan. Our results suggest that moral disengagement had a full mediation effect between the perceived threat of market competition and tendency of employees toward unethical marketing and selling practices. Moreover, ethical leadership moderated the relationship between moral disengagement and the tendency of employees toward unethical marketing practices. The research findings indicate that when field employees encounter threat perceptions due to market competition, they have a propensity toward engaging in unethical marketing and selling practices when they can activate moral disengagement. This study also found that ethical leadership negatively moderates the relationship of moral disengagement with employees’ tendency toward unethical marketing and selling practices.  相似文献

This paper builds on prior scholarly works by examining the relationship between organizing paradox (formalization and decentralization), and organizational levels of learning paradoxes, i.e. exploration and exploitation, and firms’ outcomes (organizational creativity, organizational resilience and organizational energy). Using data from 98 executives and 325 senior employees working across a diverse range of firms operating in the Middle East, the findings suggest that organizing paradox (formalization and decentralization) has a positive impact on learning ambidexterity. In addition, we also found that learning ambidexterity has a positive impact on both organizational resilience and organizational energy. Furthermore, the results indicate that learning ambidexterity mediates the relationship between organizing paradox and organizational creativity. These findings provide important insights into the micro-foundation aspects of organizational ambidexterity.  相似文献

Abstract

Aims: The efficacy and safety of oral semaglutide, the first glucagon-like peptide-1 (GLP-1) receptor agonist developed for oral administration for the treatment of type 2 diabetes, was evaluated in the PIONEER clinical trial program, and a recently published network meta-analysis allowed comparison with further injectable GLP-1 receptor agonists. The present study aimed to assess the short-term cost- effectiveness of oral semaglutide 14?mg versus subcutaneous once-weekly dulaglutide 1.5?mg, once-weekly exenatide 2?mg, twice-daily exenatide 10?µg, once-daily liraglutide 1.8?mg, once-daily lixisenatide 20?µg, and once-weekly semaglutide 1?mg, in terms of the cost per patient achieving glycated hemoglobin (HbA1c) targets (cost of control).

Materials and methods: Cost of control was calculated by dividing the annual treatment costs associated with an intervention by the proportion of patients achieving the treatment target with an intervention, with outcomes calculated for targets of HbA1c ≤6.5% and HbA1c <7.0% for all included GLP-1 receptor agonists. Annual treatment costs were accounted in 2019 United States dollars (USD), based on 2019 wholesale acquisition cost.

Results: For the treatment target of HbA1c ≤6.5%, once-weekly semaglutide 1?mg and oral semaglutide 14?mg were associated with the lowest costs of control, at USD 15,430 and USD 17,383 per patient achieving target, respectively. Similarly, the cost of control was lowest with once-weekly semaglutide 1?mg at USD 12,627 per patient achieving target, followed by oral semaglutide 14?mg at USD 13,493 per patient achieving target for the target of HbA1c <7.0%. All other interventions were associated with higher cost of control values for both targets.

Conclusions: Oral semaglutide 14?mg is likely to be cost-effective versus dulaglutide, exenatide (once weekly and twice daily), liraglutide, and lixisenatide in terms of bringing people with type 2 diabetes to glycemic control targets of HbA1c ≤6.5% and HbA1c <7.0% in the US.  相似文献

The effect of technological innovation on employment is of major concern for workers and their unions, policy makers and academic researchers. We meta‐analyse 570 estimates from 35 primary studies that estimate a derived labour demand model. We contribute to existing attempts at evidence synthesis by addressing the risks of selection bias and that of data dependence in observational studies. Our findings indicate that: (i) hierarchical meta‐regression models are sufficiently versatile for addressing both selection bias and data dependence in observational data; (ii) innovation's effect on employment is positive but small and highly heterogeneous; (iii) only a small part of residual heterogeneity is explained by moderating factors; (iv) selection bias tends to reflect preference for upholding prevalent hypotheses on the employment effects of process and product innovations; (v) country‐specific effect‐size estimates are related to labour market and product market regulation in six OECD countries in a U‐shaped fashion; and (vi) OLS estimates reflect upward bias whereas those based on time‐differenced or within estimators reflect a downward bias. Our findings point out to a range of data quality and modelling issues that should be addressed in future research.  相似文献

Scholars have recognized the important role that entrepreneurial orientation (EO) plays in driving firm performance. However, this relationship is not yet well understood and studies have sought to examine various contingencies that might mediate or moderate this relationship. This study investigates the impact of organization behavior variables on the EO – firm performance relationship. The structural model was tested using primary data from 321 South Korean industrial firms. The results show that EO is positively related to firm performance and that adaptive organizational culture and people-centered management have a multiple mediating effect on the relationship between EO and firm performance.  相似文献
