This study compares the information content of funds from operations (FFO) and net income (NI) in the real estate investment trust (REIT) industry. We find that models using FFO explain more of the variance in cumulative abnormal returns around earnings announcement dates than models using NI do. We also find that the information content of FFO differs across REITs of different sizes. FFO does not provide useful information to investors in the case of large REITs. Finally, we show that the gain or loss from sales of property is relevant to valuing large REITs.  相似文献

Managing safety and health matters require comprehensive policy intervention to change the existing culture in the ground handling operations and reducing the safety performance outcomes. This study aims to investigate the relationship between safety culture and safety performance outcome with voluntary policy intervention as the moderating effect of the relationship. The study employed a quantitative method through a survey instrument, which was participated by 423 ground handling workers from six international airports in Malaysia. The results indicated seven hypotheses in direct relationships have positive association between safety culture and safety performance construct. While for moderator relationships, there were five hypotheses found to be statistically significant and supported. The presence of voluntary policy interventions were found to be beneficial or detrimental elements for the insignificant relationships of the study. The ground handling organisation is expected to utilise these results by strengthening their organisation safety culture and prioritise safety and health matters over demand and cost.  相似文献

本文从商业银行流动性管理视角出发,探究银行微观主体行为如何影响宏观审慎与货币政策的协调。我们借鉴净稳定资金比例的设计理念,将商业银行的流动性管理行为纳入传统理论模型,刻画出两种流动性管理行为对货币政策信贷传导渠道效率的潜在影响及传导路径。在此基础上,采用我国50家商业银行2012年第1季度—2018年第2季度面板数据进行实证检验。我们发现,银行为提升长期流动性水平而进行的优化信贷资产结构的行为,能够显著提高货币政策传导效率。但是,部分净稳定资金比例较低的股份制银行和城市商业银行调整非信贷资产结构的行为则有可能降低货币政策传导效率。因此,在执行既有流动性监管措施的同时,关注与引导银行资产结构调整方式,对增强宏观审慎与货币政策的协调大有裨益。  相似文献

We investigate the relationship between a country's domestic financial development and the (composition of its) net foreign asset position using a pooled mean group estimator and data for 50 countries for the 1970–2007 period. The results show that financial development reduces a country's long-run net foreign asset position. In addition, financial development leads to higher net equity and lower net debt positions. These findings confirm the theoretical predictions of Mendoza et al. (2009). The results are robust to using different indicators of financial development and inclusion of the level of development of a country in the cointegrating relationship.  相似文献

The risk of being involved in an airplane accident is largely ignored in air passengers’ choice models. The reason presumably is that it is hard to operationalize, because objective safety indicators often involve extremely low probabilities that are hard to grasp and interpret by passengers. In this paper, we propose an operationalization that is based on the perception of safety, which is easy to understand and resonates that perceptions often influence decisions stronger than objective variables. We conceptualize that passengers form a safety perception score of a particular flight based on their perception of airline and route attributes and that this score in turn is traded-off against other flight attributes, such as ticket costs, to arrive at a flight choice. In line with this conceptualization, two stated preference experiments are conducted. In a first experiment, combinations of airline and route attributes are evaluated in terms of safety that is captured on a rating scale. In a second experiment, safety perception is treated as an attribute and traded-off against other flight attributes to arrive at a flight choice. The paper presents the results of a regression and a Panel Mixed Logit model estimated from responses obtained from a convenience sample of 161 air passengers recruited in the Netherlands. The results of both models are then combined to calculate the willingness to pay values for improvements made to a range of airline and route attributes, taking into account socio-demographic variables and psychological traits. As expected, the results indicate that the willingness to pay for improving safety decreases with higher initial safety levels.  相似文献

The Islamic Financial Services Board (IFSB) is the standard setting body for the Islamic banking industry. The IFSB, while endorsing the Basel III accord, modified the criteria to calculate the Net Stable Funding Ratio (NSFR) to cater for the unique aspects of the Islamic banking industry. In this paper, we calculated the modified NSFR of 136 Islamic banks from 30 jurisdictions between 2000 and 2013 and explored the potential impact the requirements of this ratio has on the financial stability of Islamic banks after controlling for bank, country, and market-specific variables. The empirical findings suggest that the modified NSFR has a positive impact on the financial stability of Islamic banks during the sample period. However, the marginal impact of the NSFR on stability diminishes as the size of the bank increases. The results remained robust after applying an alternative measure of stability and using an alternative estimation model based on an instrumental variable approach. These results validate the use of the IFSB’s modified NSFR for Islamic banks as a regulatory measure.  相似文献

加入WTO以后中国金融发展面临的主要问题是既要增强国际竞争力,又必须维护国家的金融安全.但目前中国的金融结构存在着严重缺陷,制约了中国金融业的进一步发展与国际竞争力的提升,对金融稳定与安全产生了诸多的不利影响,因此,中国金融发展不能继续依赖数量增长和加快速度的路径,需要转变思路,以结构调整为重点推进中国金融的改革开放与发展,寻求提升国际竞争力与安全性相统一的金融发展之路.  相似文献
