This study examines the safe haven properties of top five crypto-currencies, oil and gold for the five gulf cooperation council countries in view of COVID-19 period through a nonlinear and asymmetric framework NARDL methodology to uncover short- and long-run asymmetries. Using daily data from January 2019 to April 2020, we find that Bitcoin and Ethereum are safe haven assets for GCC in instability;Bitcoin is a safe haven for Oman, Saudi Arabia and Abu Dhabi. Ethereum is a safe haven for Bahrain, Kuwait and Qatar. Further, for Kuwait, Qatar, Saudi Arabia and Abu Dhabi, oil is a safe haven asset in mitigated period. We also notice that the strategies of hiding differ interestingly for all countries except for Saudi Arabia that does not significantly change its strategies. Thus, portfolio managers may consider few eligible crypto-currencies and oil for their inclusion into the portfolio to hedge risk. While, speculators acting in both stock and crypto market may go for a spread strategy. Our research is useful for portfolio managers and financial advisors looking for the best of crypto’s, gold and oil to hedge shocks in stock market indices.

本研究通过非线性和非对称框架NARDL方法,考察了2019冠状病毒病期间五个海湾合作委员会国家五大加密货币、石油和黄金的避险属性,以揭示短期和长期的不对称性。利用2019年1月至2020年4月的每日数据,我们发现比特币和以太坊是海湾合作委员会在不稳定时期的避险资产;比特币是阿曼、沙特阿拉伯和阿布扎比的避险资产。以太坊是巴林、科威特和卡塔尔的避风港。此外,对科威特、卡塔尔、沙特阿拉伯和阿布扎比而言,石油是缓和时期的避险资产。我们还注意到,除了沙特阿拉伯没有显著改变其策略外,所有国家的隐藏策略都有有趣的不同。因此,投资组合经理可能会考虑将少数符合条件的加密货币和石油纳入投资组合以对冲风险。而在股票和加密市场上的投机者可能会采取点差策略。我们的研究对投资组合经理和财务顾问来说很有用,他们正在寻找最好的加密货币、黄金和石油来对冲股市指数的冲击。版权所有©2021 Inderscience Enterprises Ltd。

Impact of corporate governance practices on financial performance: evidence from non-financial sector of Pakistan 公司治理做法对财务业绩的影响:来自巴基斯坦非金融部门的证据

This study aims to investigate the impact of corporate governance practices on the financial performance of Pakistani listed firms. For this purpose, we use the panel data of 65 non-financial listed firms from 2010 to 2017. Our framework of analysis is based on the agency and stewardship theories. We measure corporate governance practices through various gauges, including board size, board independence, CEO duality, institutional ownership, managerial ownership, ownership concentration, and foreign ownership. Applying the fixed-effect and random-effect models in a panel setting, this empirical investigation reveals that board size, institutional ownership, managerial ownership, and ownership concentration accelerate the financial performance of the non-financial sector of Pakistan. However, we could not find such evidence on CEO duality, board independence and foreign ownership. Consistent with the convergence theory, our empirical findings reveal that higher managerial ownership reduces agency cost issue and ultimately enhances the performance, profitability, and shareholder's wealth.
本研究旨在调查公司治理实践对巴基斯坦上市公司财务业绩的影响。为此,我们使用了2010年至2017年65家非金融上市公司的面板数据。我们的分析框架基于代理和管理理论。我们通过各种衡量标准来衡量公司治理实践,包括董事会规模、董事会独立性、CEO双重性、机构所有权、管理层所有权、所有权集中度和外国所有权。在面板设置中应用固定效应和随机效应模型,本实证研究表明,董事会规模、机构所有权、管理层所有权和所有权集中度加速了巴基斯坦非金融部门的财务绩效。然而,在CEO二元性、董事会独立性和外资持股方面,我们却找不到这样的证据。与收敛理论一致,我们的实证结果表明,更高的管理层所有权减少了代理成本问题,并最终提高了绩效、盈利能力和股东财富。

Have pure-play internet banks caught up with traditional and hybrid banks over the past decade 在过去十年中,纯互联网银行是否赶上了传统银行和混合银行

This paper investigates the performance of pure-play internet (PPI) banks compared to their traditional and hybrid counterparts over the past 18 years. All 11 surviving PPI banks were hand screened and matched with 110 control banks randomly selected based on total assets from the FDIC website. Our pooled OLS regressions with robust errors show that PPI banks have lower profitability and are less cost efficient than their counterparts. This may be because PPI banks still need time to accumulate experience and scale effects. PPI banks also do not attract more deposits or invest more in securities than traditional and hybrid banks. However, they do have less risk in terms of bad loans than traditional and hybrid comparables.
本文调查了过去18年来,与传统和混合型银行相比,纯互联网银行的表现。所有11家幸存的PPI银行都经过了手工筛选,并根据FDIC网站上的总资产随机选择了110家对照银行。我们的带有稳健误差的OLS回归表明,PPI银行的盈利能力较低,成本效益也低于同行。这可能是因为PPI银行仍需要时间来积累经验和规模效应。PPI银行也没有比传统银行和混合银行吸引更多的存款或更多的证券投资。然而,就不良贷款而言,它们确实比传统和混合可比产品的风险更小。
