Sustainable and ethical leadership in the financial industry expand in importance since the financial crisis of 2007–2009. This research examined the level of sustainable and ethical leadership of leaders in mortgage loan originator (MLO) organizations, as perceived by loan originators. The Perceived Leadership Survey (PLIS) developed by Craig and Gustafson (Leadersh Q 9(2):127–145, 1998) and the Sustainable Leadership Questionnaire (SLQ) developed by McCann and Holt (Int J Sustain Strat Manage 2(2):204–210, 2011) were utilized for this research. The survey results yielded high levels of both ethical and sustainable leadership. Employees also felt their leadership was encouraging ethical and sustainable behavior. However, correlations between the PLIS and SLQ did not prove to be dependent or closely correlated. 相似文献

A binomial approximation to a diffusion is defined as 'computationallysimple' if the number of nodes grows at most linearly in thenumber of time intervals. It is shown how to construct computationallysimple binomial processes that converge weakly to commonly employeddiffusions in financial models. The convergence of the sequenceof bond and European option prices from these processes to thecorresponding values in the diffusion limit is also demonstrated.Numerical examples from the constant elasticity of variancestock price and the Cox, Ingersoll, and Ross (1985) discountbond price are provided. 相似文献

The upstairs market for large-block transactions: analysis and measurement of price effects 总被引:12,自引:0,他引:12
This article develops a model of the upstairs market where ordersize, beliefs and prices are determined endogenously. We testthe model's predictions using unique data for 5,625 equity tradesduring the period 1985 to 1992 that are known to be upstairstransactions and are identified as either buyer or seller initiated.We find that price movements prior to the trade date are significantlypositively related to trade size, consistent with informationleakage as the block is 'shopped' upstairs. Further, the temporaryprice impact or liquidity effect is a concave function of ordersize, which may result from upstairs intermediation. 相似文献

The Cox, Ross, and Rubinstein binomial model is generalizedto the multinomial case. Limits are investigated and shown toyield the Black-Scholes formula in the case of continuous samplepaths for a wide variety of complete market structures. In thediscontinuous case of Merton-type formula is shown to result,provided jump probabilities are replaced by their correspondingArrow-Debreu prices. 相似文献

The use of corporate social disclosures in the management of reputation and legitimacy: a cross sectoral analysis of UK Top 100 Companies 总被引:10,自引:0,他引:10
Recent years have witnessed an escalation in corporate social reporting (CSR) by UK companies (Gray, Kouhy and Lavers 1995). Whilst some elements of CSR reporting are required by law, much of it represents voluntary reporting. By investigating the non‐mandatory reporting of two aspects of social responsibility, corporate community involvement (CCI) and environmental impact, this paper seeks to explore why companies choose to make such disclosures. It specifically asks whether companies are primarily motivated by the strategic need to manage their reputation and legitimacy rather than by the recognition of their ethical accountability, which is the stated purpose of reports produced by cutting edge companies (Clarke 1998). 相似文献

Under the current care delivery model, persons with chronic illnesses, such as diabetes, are not receiving all recommended interventions and failing to meet targeted outcomes. The Chronic Care Model provides a framework for new approaches and roles for many members of the multidisciplinary team. Using the Chronic Care Model as a guide, a group of hospital-based clinics in an academic system incorporated nurse practitioners into the care model for patients with diabetes. Through use of planned visits, a patient registry, drug intensification protocols, and collaboration with other members of the team, the pilot sample improved processes of care and clinical outcomes. Use of nurse practitioners in this model of care for chronically ill patient populations has economic implications, as the payers begin to pay for performance. 相似文献
