Liquid assets are critical for banking operations. They guarantee avoiding liquidity risk and widens managerial decision options to invest in emerging profitable projects; however, holding extra liquidity entails opportunity costs. Accordingly, empirical literature does not provide a conclusive relationship between liquidity and profitability. The purpose of this research is to analyze the asymmetric effects of holding liquid assets by commercial banks on their profitability. Parallel to a detailed review of contradicting theories and empirical evidence, we have developed an econometric model to capture the nonlinear effects of liquidity on performance. The proposed model is tested for a sample of seven listed Iranian commercial banks during 2006-2018 by Arellano-Bond dynamic panel-data estimation. We found that the nonlinear relationship, if any, is not an inverse U as Bordeleau and Graham (2010) suggested. Results show a positive (holding more liquid assets increases the profitability of Iranian banks), and even an accelerating effect for liquidity, likely due to the low level of liquid assets maintained by Iranian banks. implementation of Basel III. They gathered twenty years of data for more than 6000 banks before 2000 and for more than 5000 banks between 2000 to 2012. The results show that banks react to regime change, and their behavior does not match the pre-regulation
流动资产对银行业务至关重要。它们保证避免流动性风险,并扩大管理决策选择,投资于新兴的盈利项目;然而,持有额外的流动性需要付出机会成本。因此,实证文献并没有提供流动性和盈利能力之间的结论性关系。本研究的目的是分析商业银行持有流动资产对其盈利能力的不对称影响。在详细回顾相互矛盾的理论和经验证据的同时,我们开发了一个计量经济学模型来捕捉流动性对绩效的非线性影响。通过Arellano-Bond动态面板数据估计,对2006-2018年期间七家伊朗上市商业银行的样本进行了模型测试。我们发现,如果存在非线性关系,也不是Bordeleau和Graham(2010)提出的逆U型关系。结果显示出积极的(持有更多的流动资产增加了伊朗银行的盈利能力),甚至是对流动性的加速效应,这可能是由于伊朗银行保持的低水平流动资产。实施巴塞尔协议III。他们收集了2000年之前6000多家银行20年的数据,以及2000年至2012年5000多家银行的数据。结果表明,银行会对制度变化做出反应,其行为与监管前不匹配

A Study on the Contribution of Foreign Direct Investment to Economic Growth in Afghanistan 外国直接投资对阿富汗经济增长的贡献研究
Pub Date : 2021-12-01 DOI: 10.52547/jme.16.4.555

Foreign Direct Investment (FDI) is frequently regarded as a key driver of global economic integration because it brings job opportunities, capital investment, and business experience. The current study examines the impact of foreign direct investment on Afghanistan's economic growth using time-series data from 2007 to 2019, which are collected from the World Bank and the International Monetary Fund's annual macroeconomic data sources for the country. Foreign direct investment (FDI), trade (Trd), inflation (InfR), and real interest rate (Int) are independent variables for regressing on this country's gross domestic product (GDP), while "GDP" is as a dependent variable. The method of ordinary least squares (OLS) was utilized to investigate the impact of these variables on Afghanistan's economic growth. For unit root test, the Augmented Dickey-Fuller (ADF) one was utilized, while co-integration, Granger causality, and the Vector Error Correction Model (VECM) were all used to capture two-way linkages between variables and were shown to hold in the long run. Our findings indicate that foreign direct investment and trade have a negative and significant impact on Afghanistan's economic performance in the short run but that all variables except inflation have a positive and significant impact on economic growth in the long run. According to the study, a rigorous policy mix is required to absorb "FDI" while supporting infant industries and reducing Afghanistan's balance of payments deficit for growth and future development.
外国直接投资(FDI)经常被视为全球经济一体化的关键驱动力,因为它带来了就业机会、资本投资和商业经验。本研究使用2007年至2019年的时间序列数据考察了外国直接投资对阿富汗经济增长的影响,这些数据收集自世界银行和国际货币基金组织的年度宏观经济数据来源。外商直接投资(FDI)、贸易(Trd)、通货膨胀(InfR)和实际利率(Int)是对该国国内生产总值(GDP)进行回归的自变量,而“GDP”作为因变量。利用普通最小二乘(OLS)方法来调查这些变量对阿富汗经济增长的影响。对于单位根检验,使用了增广的Dickey-Fuller (ADF)检验,而协整,格兰杰因果关系和向量误差修正模型(VECM)都用于捕获变量之间的双向联系,并被证明在长期内保持不变。我们的研究结果表明,外国直接投资和贸易在短期内对阿富汗的经济表现有负面和显著的影响,但从长期来看,除通货膨胀外的所有变量对经济增长都有积极和显著的影响。根据这项研究,需要一个严格的政策组合来吸收“外国直接投资”,同时支持新兴产业,减少阿富汗的国际收支赤字,以促进增长和未来发展。

This study investigates monetary and financial shocks on macroeconomic variables, focusing on the role of banking intervention. For this purpose, a Keynesian dynamic stochastic general equilibrium (DSGE) model is designed for Iran’s economy that involves financial and banking sectors. The results of the model simulation show that the financial accelerator theory works in the Iranian economy. Also, the intermediary role is confirmed by the impulse response function. In other words, economic policies can impress on macroeconomic indicators more when banks intervene in the economy. Therefore, to control the effects of economic shocks on banks' performance, it has been suggested that monetary policymakers pay attention to the important roles of financial markets in the transfer mechanism and monetary policy intensity. On the other hand, because of mandatory rules of interest rates determination, banks have to establish a commission and nonprofit services instead of sharing income to decrease the effect of economic shocks.
本研究探讨了货币和金融冲击对宏观经济变量的影响,重点关注银行干预的作用。为此,针对涉及金融和银行业的伊朗经济,设计了凯恩斯动态随机一般均衡(DSGE)模型。模型仿真结果表明,金融加速器理论在伊朗经济中是有效的。同时,脉冲响应函数也证实了中介作用。换句话说,当银行干预经济时,经济政策对宏观经济指标的影响更大。因此,为了控制经济冲击对银行绩效的影响,建议货币政策制定者重视金融市场在转移机制和货币政策强度中的重要作用。另一方面,由于利率决定的强制性规则,银行必须建立佣金和非营利性服务,而不是分享收入,以减少经济冲击的影响。

Corporate governance of banks is one of the most important structures required by banks to maintain the health and stability of banks, which can play an important role in managing banks' risk. This paper examines the effect of corporate governance on liquidity risk management, credit risk management, and total bank risk management. We used board structure effectiveness, transparency, and responsibility as corporate governance indicators. The financial ratio approach is also used to measure risk management. The period under review was 2006-2018. In addition to corporate governance criteria, other explanatory variables affecting banks' risk management have also been used. This paper used the performing unit root, cointegration, and F-Limmer tests to ensure panel estimation. Given the impact of past banks' risk management on current risk management, this variable has also been modeled as an explanatory variable. For this reason, the GMM method has been used to estimate the models in question. Given the importance of bank size in corporate governance on bank risk management, Banks are divided into large and small groups, so the effect of corporate governance in large and small banks has also been investigated on bank risk management. The results show that compliance with corporate governance criteria positively affects banks' risk management. However, due to weak corporate governance in large banks, corporate governance in large banks hurts bank risk management. are computed using asymptotic Chi-square distribution.
银行公司治理结构是银行维持健康稳定所需要的最重要的结构之一,对银行风险管理具有重要作用。本文考察了公司治理对流动性风险管理、信用风险管理和银行整体风险管理的影响。我们使用董事会结构、效率、透明度和责任作为公司治理指标。财务比率法也用于衡量风险管理。所审查的期间为2006-2018年。除了公司治理标准外,还使用了影响银行风险管理的其他解释变量。本文使用执行单位根、协整和F-Limmer检验来确保面板估计。鉴于过去银行风险管理对当前风险管理的影响,该变量也被建模为解释变量。出于这个原因,GMM方法已被用于估计所讨论的模型。鉴于银行规模在公司治理中对银行风险管理的重要性,我们将银行分为大银行和小银行,因此我们也研究了大银行和小银行的公司治理对银行风险管理的影响。结果表明,遵守公司治理标准对银行风险管理有正向影响。然而,由于大银行的公司治理薄弱,大银行的公司治理不利于银行风险管理。使用渐近卡方分布计算。

Explaining Heterogeneity in Risk Preferences Using a Finite Mixture Model 用有限混合模型解释风险偏好的异质性
Pub Date : 2021-12-01 DOI: 10.52547/jme.16.4.533

This paper studies the effect of the space (distance) between lotteries' outcomes on risk-taking behavior and the shape of estimated utility and probability weighting functions. Previously investigated experimental data shows a significant space effect in the gain domain. As compared to low spaced lotteries, high spaced lotteries are associated with higher risk aversion for high probabilities of gain and higher risk-seeking for low probabilities of gain. Hence, the investigation is carried under cumulative prospect theory that respects framing effect and characterizes risk attitudes with respect to probabilities and outcomes. The observed certainty equivalents of lotteries are assumed to be driven by cumulative prospect theory. To estimate the parameters of cumulative prospect theory with maximum likelihood, the usual error term is added. The cumulative prospect theory is incapable of explaining the space effect as its parameters cannot explain the average behavior. Taking account of heterogeneity, a two-component mixture model shows that behavioral parameters of around 25% of the sample can explain the observed differences in relative risk aversions. The results confirm the previous findings of aggregation bias associated with representative-agent models. Furthermore, the results have implications for experimental designs as high space between lotteries' outcomes is required to guarantee the curvature of utility functions.
本文研究了彩票结果之间的空间(距离)对风险行为的影响以及估计效用和概率加权函数的形状。先前研究的实验数据表明,增益域中存在显著的空间效应。与低间隔彩票相比,高间隔彩票与高概率收益的更高风险厌恶和低概率收益的更高风险寻求有关。因此,调查是在累积前景理论下进行的,该理论尊重框架效应,并根据概率和结果表征风险态度。我们假设观察到的彩票的确定性等效物是由累积前景理论驱动的。为了最大似然估计累积前景理论的参数,加入了常用误差项。累积前景理论不能解释空间效应,因为其参数不能解释平均行为。考虑到异质性,双组分混合模型表明,约25%的样本的行为参数可以解释观察到的相对风险厌恶的差异。研究结果证实了先前关于聚集偏差与代表代理模型相关的发现。此外,该结果对实验设计具有启示意义,因为彩票结果之间的高空间需要保证效用函数的曲率。

The technological revolution has spread over today's world, and it is clearly seen in banking, especially electronic banking. E-Banking has many dimensions, criteria, and components, and judging its progress based on dimensions leads to difficulty and bias. There is also a lack of comprehensive information references in the literature. Therefore, introducing a combinational index to accurately assess its progress is inevitable. In this research, the E-Banking Progress Index (E-BPI), which focuses on the infrastructures and the tools of e-banking and has five dimensions: Technical and Communicational Infrastructures; Services; Cultural-Educational Infrastructures; Security and Supervision; and Legal-Regulatory Infrastructures is created. It also has several applications in investigating the progress of e-banking in a bank or a country and comparing it among banks or countries. This research, using Analytic Hierarchy Process (AHP), leads to the introduction of a combinational index to measure the progress of e-banking, which is able to analyze its strength and weakness. E-BPI provides a score between 0 and 1. The more the score, the stronger the e-banking is. 130 The research findings indicate a positive and significant relationship between e-services and customers' from
技术革命已经蔓延到当今世界,在银行业,尤其是电子银行方面表现得尤为明显。电子银行有许多维度、标准和组成部分,基于维度来判断其进展会带来困难和偏差。文献中也缺乏全面的信息参考。因此,引入一个综合指标来准确评估其进展是不可避免的。在本研究中,电子银行进步指数(E-BPI)主要关注电子银行的基础设施和工具,有五个维度:技术和通信基础设施;服务;文化教育基础设施;安全与监管;建立法律监管基础设施。它在调查一家银行或一个国家的电子银行的进展以及在银行或国家之间进行比较方面也有一些应用。本研究运用层次分析法(AHP),引入一个综合指标来衡量电子银行的发展进度,分析其优势和劣势。E-BPI的评分范围在0到1之间。分数越高,说明电子银行越强。研究结果表明,电子服务与顾客满意度之间存在显著的正相关关系

Stock Exchange Investors have paid more attention to the banking group in recent years so that in many cases, the direction of the banking index has changed the general direction of the market. Therefore, exploring the banking index fluctuation is important from the point of view of investors as well as the direction of the market. The purpose is to examine the effectiveness and direction of news, as one of the most important factors in the formation of volatility, on the banking group index in Tehran Stock Exchange by using 1460 daily records during 2018-2019 and the GARCH family's method. The data were collected for four different newsgroups, including economic, political, psychological, and financial. After that, the news that had more relationship with the banking group was separated to underscore in the weighting stage and divided into the positive and negative news, according to the perspectives of capital market experts and economic elites. The results indicated that newsgroups have a significant effect on the group index, and only the negative political model on the banking group has an asymmetric effect. The results indicated that political and economic news has a positive and significant impact on banking index fluctuations.
近年来,证券交易所投资者对银行集团的关注越来越多,以至于在很多情况下,银行指数的走势改变了市场的大方向。因此,无论是从投资者的角度,还是从市场的方向,对银行业指数波动进行探讨都是非常重要的。目的是通过使用2018-2019年期间的1460条每日记录和GARCH家族方法,研究新闻作为形成波动性的最重要因素之一对德黑兰证券交易所银行集团指数的有效性和方向。这些数据是为四个不同的新闻组收集的,包括经济、政治、心理和金融。之后,根据资本市场专家和经济精英的观点,在权重阶段将与银行集团关系更密切的新闻分开强调,分为正面新闻和负面新闻。结果表明,新闻组对集团指数有显著影响,只有负面政治模型对银行集团有不对称影响。结果表明,政经新闻对银行指数波动具有显著的正向影响。

Economic growth is the most common goal in any economy, and capital is one of the most important determinants of growth. In the last few decades, the use of securities in various countries' capital markets has expanded and has become an essential part of the economic system supplying the capital need for investors and other institutions. This study aims to analyze the effect of securities used to finance banks (securitization) on economic growth. For this purpose, the theoretical analysis method is used in the framework of a Dynamic Stochastic General Equilibrium (DSGE) model. The theoretical model used is based on Frank Ramsey's (1928) economic growth model. To transform this model into a suitable model for research, the shadow banking system and securitization have been added. The model is then simulated using the calibration method and using the real data of the US economy; then, the macroeconomic changes and fluctuations created by bank securities are explained and analyzed. According to the research findings, issuing securities by banks will lead to slower economic growth. Therefore, it is recommended to avoid the use of securitization in banking.
经济增长是任何经济体最共同的目标,而资本是增长最重要的决定因素之一。在过去的几十年里,各国资本市场对证券的使用已经扩大,并已成为经济体系的一个重要组成部分,为投资者和其他机构提供资本需求。本研究旨在分析银行融资证券(证券化)对经济增长的影响。为此,在动态随机一般均衡(DSGE)模型的框架中采用了理论分析方法。所使用的理论模型是基于Frank Ramsey(1928)的经济增长模型。为了将这个模型转化为一个适合研究的模型,我们加入了影子银行体系和证券化。然后利用标定方法和美国经济实际数据对模型进行了仿真;然后,对银行证券造成的宏观经济变化和波动进行了解释和分析。根据研究结果,银行发行证券将导致经济增长放缓。因此,建议在银行业务中避免使用证券化。
