Economists have exploited the social accounting matrix in linear economic models to analyze the effect of some variables such as government spending, investment, and export on other economic indicators including total output, employment, household income, and economic growth. In this paper, the influence of investment injection on some economic indicators is analyzed. In addition, to gather different indicators in a general view, these economic indicators are applied as inputs and outputs in a data envelopment analysis model. Overall, to get to the best possible economic conditions, a fair revenue allocation method is used based on a data envelopment analysis model to determine each economic sector’s quota of investment. Next, a kind of fair-biased allocation method improving the economic conditions in comparison to the prior model is proposed. Finally, the whole process for Iran’s social accounting matrix and subsequent results are presented.

COVID-19 has caused severe disruptions in global economic activities, and its impacts on stock markets cannot be overemphasized. The study employs market model and event study approach with four events (WHO announcement of COVID-19 as a global health emergency, confirmed infections, confirmed deaths, and vaccination) to examine the reactions of four African regional blocs’ markets to the pandemic from September 1, 2019, to August 31, 2021, to estimate the average abnormal returns of each regional bloc. On the day of the WHO announcement, we document insignificant negative average abnormal returns in the Northern bloc. We also document significant negative average abnormal returns for infections in all but the Northern bloc on the event day. The Western bloc generated the highest significant negative average abnormal return (-43 per cent) on the day COVID-19 death was confirmed on the continent. We finally document insignificant average abnormal returns from weeks 1 to 20 after the first vaccination in the Northern and Eastern blocs. The study recommends that investors, portfolio managers, and speculators not panic during similar pandemics since they can generate significant abnormal returns and diversify their investment holdings across the four regional blocs in Africa, as demonstrated by the COVID-19 pandemic.

The phenomenon of the bullwhip effect (BWE) has become a pressing concern in contemporary supply chain management. Every echelon of the supply chain faces the negative consequences of BWE somehow. So, it is crucial to determine the reasons responsible for the BWE to mitigate the consequences. The boutique industry in Bangladesh is a rapidly growing industrial sector. In this study, we focused on finding the reasons and consequences of the bullwhip effect on the boutique industry in Dhaka city. The main targets of this study are to examine the underlying reasons for the BWE, identify the most significant causes from the perspective of Dhaka city, and determine the major consequences of the bullwhip effect. Studies of previous literature and consultation with experts have identified sixteen common causes behind the bullwhip effect. This study uses a survey-based method; respondents are chosen through clustered sampling. Necessary data have been collected with a semi-organized inquiry form. Among all the 16 causes, six causes are found to be the most significant causes from the perspective of retailers and wholesalers. SPSS Version 26 has been used for statistical analysis to make the final decision. We also found ten consequences commonly faced by these two echelons of the boutiques' supply chain because of the bullwhip effect. These are high inventory costs, workforce wastages and higher labor costs, higher replenishment lead-time, higher transportation costs, tension in the buyer-supplier relationship, product unavailability, loss of profit, poor customer service, etc.
牛鞭效应(BWE)现象已成为当代供应链管理中一个迫切关注的问题。供应链的每一个层次都面临着BWE的负面影响。因此，确定造成BWE的原因以减轻后果至关重要。孟加拉国的精品行业是一个快速发展的工业部门。在本研究中，我们的重点是寻找牛鞭效应对达卡市精品产业的原因和后果。本研究的主要目标是研究BWE的潜在原因，从达卡市的角度找出最重要的原因，并确定牛鞭效应的主要后果。对以往文献的研究和对专家的咨询已经确定了牛鞭效应背后的16个常见原因。本研究采用基于调查的方法;受访者是通过整群抽样的方式选择的。用半组织的询问表收集了必要的数据。在这16个原因中，从零售商和批发商的角度来看，有6个原因是最重要的。使用SPSS Version 26进行统计分析，做出最终决定。我们还发现了由于牛鞭效应，精品店供应链的这两个梯队共同面临的十个后果。这些是高库存成本、劳动力浪费和更高的劳动力成本、更高的补货前置时间、更高的运输成本、紧张的买方-供应商关系、产品缺货、利润损失、糟糕的客户服务等。

This paper investigates the potential correlation between the performance of Audit Committees (AC) and Audit Quality (AQ). Data is derived from capital goods firms listed on the main stock exchange of Saudi Arabia (TASI). Logit regression analysis is used for this purpose and the dependent variable of BIG4 is used as a proxy for AQ, while AC meetings (ACMT), size (ACSZ), and AC members with a financial background (ACEX) are used as explanatory variables. The results show no statistical association between ACMT and AQ. However, the analysis indicates a positive statistical relationship between ACSZ and AQ, and a strong negative association between ACEX and AQ. These findings provide insights into the impact of AC attributes on AQ, and would be of interest to decision makers, policy-makers, investors, and senior management.

Portfolio optimization aims to minimize risk and maximize return on investment by determining the best combination of securities and proportions. The variance in portfolio optimization models is typically used for a measure of risk. Over the last few decades, portfolio optimization utilizing a variety of risk measures has grown significantly, and many studies have been conducted. Therefore, this paper provides a systematic review of risk measures for portfolio optimization using bibliometric analysis and maps to analyze the evolution and trends of 682 articles published between 2000 and 2022. Throughout this analysis, communication networks among articles, authors, sources, countries, and keywords are explored. Furthermore, a classification of risks and risk measures were presented to demonstrate a comprehensive overview of the field, and the top 50 papers were analyzed to determine which risk measures were most often used in recent studies.

Silver is a metal that offers significant value to both investors and companies. The purpose of this study is to make an estimation of the price of silver. While making this estimation, it is planned to include the frequency of searches on Google Trends for the words that affect the silver price. Thus, it is aimed to obtain a more accurate estimate. First, using the Latent Dirichlet Allocation method, the keywords to be analyzed in Google Trends were collected from various articles on the Internet. Mining data from Google Trends combined with the information obtained by LDA is the new approach this study took, to predict the price of silver. No study has been found in the literature that has adopted this approach to estimate the price of silver. The estimation was carried out with Random Forest Regression, Gaussian Process Regression, Support Vector Machine, Regression Trees and Artificial Neural Networks methods. In addition, ARIMA, which is one of the traditional methods that is widely used in time series analysis, was also used to benchmark the accuracy of the methodology. The best MSE ratio was obtained as 0,000227131 ± 0.0000235205 by the Regression Trees method. This score indicates that it would be a valid technique to estimate the price of "Silver" by using Google Trends data using the LDA method.

This study examines the factors affecting audit fees in firms listed primarily in Sub-Saharan Africa countries by focusing on the relationship between ownership structure and audit fees. The study uses an unbalanced panel dataset of 531 observations of non-financial firms collected from annual reports for the years 2005 to 2009. The findings show that audit fees vary with ownership structure. Particularly, the study shows managerial ownership and concentrated ownership are negatively related to audit fees, whereas foreign ownership is related positively to audit fees. This study provides valuable insights on effects of ownership structure on audit fees pricing. Specifically, the study emphasizes that decisions of pricing of audit fees should consider characteristics of the ownership structure of a firm. The study makes contributions to the literature that focuses on the nexus between corporate governance and audit fees. Particularly, the findings provide empirical evidence of impacts of ownership structure on audit fees in Sub-Saharan African context, which is characterized by less developed financial markets and a weak institutional environment relative to developed countries where most studies are conducted.
