Cabin crews are crucial to the cabin safety performance of airlines, and may enhance air travel safety and alleviate passenger concerns. Within the limited literature devoted to cabin crew related research, this study aims to examine the causal relationships among “job demands”, “job resources” and cabin crew safety behaviors. Data from a survey of 339 flight attendants working for Taiwanese international airlines were analyzed using structural equation modeling. A variety of fit indices confirmed the overall model fit, and all the paths in the model were statistically significant. Framed in the context of the job demands-resources model, the results reveal negative causality between “job demands” and “cabin crew safety behaviors”, whereas “job resources” are positively related to “upward safety communication”, “in-role” and “extra-role” safety behaviors. The implications of the results for practitioners and future research are discussed. 相似文献

Little progress has been made so far in addressing—in a comprehensive way—the negative externalities caused by excessive maturity transformation and the implications for effective liquidity regulation of banks. The SRL model combines option pricing theory with market information and balance sheet data to generate probabilistic measure of systemic liquidity risk. It enhances price-based liquidity regulation by linking a bank’s maturity mismatch impacting the stability of its funding with those characteristics of other banks, subject to individual changes in risk profiles and common changes in market conditions impacting funding and market liquidity risk. This approach can then be used (i) to quantify an individual institution’s time-varying contribution to expected losses from system-wide liquidity shortfalls and (ii) to price insurance premia that provide incentives for banks to internalize the social cost of their individual funding decisions. 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

中国贸易条件变动趋势分析——基于1993-2017年月度数据的研究 总被引:1,自引:0,他引:1
基于1993-2017年月度数据研究发现:中国三大贸易条件指数(2010=100)中价格贸易条件上下波动明显,标准差为6.0;收入贸易条件长期稳步上升,近三年相对于最高点下降了15%~20%;要素贸易条件一直呈上升趋势,标准差为66.2.人民币汇率一次性大幅度变动时,中国价格贸易条件有显著变动.人民币显著升值时,价格贸易条件马上明显改善,但维持时间不长,随后又发生逆转.人民币一次性大幅度贬值导致价格贸易条件长期恶化有一定的时滞.国外发生经济或金融危机而中国宏观经济较稳定发展期间,中国价格贸易条件改善.为此,我国应积极推动人民币汇率向均衡汇率靠拢,针对性地采取限产计划,以提升国际分工地位,从根本上改善贸易条件和增加经济福利. 相似文献

Net neutrality rules have been implemented in many developed countries, often in response to concerns over network operator market power and potential blocking or throttling of content. However, developing countries typically have significantly lower levels of internet penetration and usage. Market power in respect of internet access looks quite different given that mobile is the predominant means of connection and there are often three or more mobile operators. In South Africa, there is a quasi-monopoly in the paid satellite broadcasting market and broadband providers zero-rating content from third parties (such as Netflix) may bring about more competition. We test the main theories of harm arising in the net neutrality debate, including network operator market power and exclusion among content providers using data on the number of announced prefixes and peers and IP addresses and considering examples of bundling and zero-rating conduct by operators. We find that net neutrality rules are less likely to be required in South Africa and other developing countries and that strict enforcement of such rules could in fact hinder competition in markets for content, telecommunications networks and other related markets. 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

Net share issues and the cross‐section of equity returns under a dividend imputation tax system 下载免费PDF全文
Despite considerable empirical evidence reporting a negative relationship between net share issuance and subsequent returns, it remains unresolved whether this anomaly is explained by risk or investor irrationality. This study examines the net share issuance anomaly using seasoned equity offerings before and after the introduction of an imputation tax system. We report robust evidence of a negative relationship between net share issuance and returns post‐imputation, but no relationship pre‐imputation. Our results provide evidence to support the international pervasiveness of the net share issuance anomaly, but more importantly suggest that this anomaly may be explained by risk. 相似文献

Internet users have suffered collateral damage in tussles over paid peering between large ISPs and large content providers. Paid peering is a relationship where two networks exchange traffic with payment, which provides direct access to each other’s customers without having to pay a third party to carry that traffic for them. The issue will arise again when the United States Federal Communications Commission (FCC) considers a new net neutrality order.We first consider the effect of paid peering on broadband prices. We adopt a two-sided market model in which an ISP maximizes profit by setting broadband prices and a paid peering price. We analytically derive the profit-maximizing prices, and show that they satisfy a generalization of the well-known Lerner rule. Our result shows that paid peering fees reduce the premium plan price, increase the video streaming price and the total price for premium tier customers who subscribe to video streaming services; however, the ISP passes on to its customers only a portion of the revenue from paid peering. ISP profit increases but video streaming profit decreases as an ISP moves from settlement-free peering to paid peering price.We next consider the effect of paid peering on consumer surplus. We find that consumer surplus is a uni-modal function of the paid peering fee. The paid peering fee that maximizes consumer surplus depends on elasticities of demand for broadband and for video streaming. However, consumer surplus is maximized when paid peering fees are significantly lower than those that maximize ISP profit. However, it does not follow that settlement-free peering is always the policy that maximizes consumer surplus. The peering price depends critically on the incremental ISP cost per video streaming subscriber; at different costs, it can be negative, zero, or positive. 相似文献
