Mutual funds, as significant participants in financial markets, play a crucial role in the formation of asset pricing. The relationship between herding behavior of mutual funds and mispricing has been a subject of intense debate among scholars. In this paper, we investigate the asymmetric impact of mutual fund herding on price deviation and explore the underlying mechanism. In terms of research design, this study selects relevant data on mutual fund holdings and stock trading in the Chinese A-share market from 2010 to 2023, we examine whether herding behavior leads to mispricing, specifically focusing on the asymmetric effects of herding buying and herding selling on stock price deviation from intrinsic value. This study distinguishes the trading direction of mutual fund herding behavior and separately examines the relationship between herding buying behavior and herding selling behavior with stock price deviation. Our empirical findings reveal that buying herding behavior is linked to positive price deviations from intrinsic value. However, selling herding behavior shows no significant relationship with price deviation. Furthermore, our results provide evidence that the herding buying of mutual funds stimulates similar trading sentiments among other market participants and contributes to the formation of market bubbles, while herding selling prompts counterbalancing trades, mitigating the impact of price deviation.
共同基金作为金融市场的重要参与者,在资产定价的形成过程中发挥着至关重要的作用。共同基金的羊群行为与错误定价之间的关系一直是学者们争论的焦点。本文研究了共同基金羊群行为对价格偏离的非对称影响,并探讨了其内在机制。在研究设计上,本研究选取2010-2023年中国A股市场共同基金持股和股票交易的相关数据,考察羊群行为是否会导致错误定价,具体关注羊群买入和羊群卖出对股价偏离内在价值的非对称影响。本研究区分了共同基金羊群行为的交易方向,并分别研究了羊群买入行为和羊群卖出行为与股价偏离的关系。我们的实证研究结果表明,羊群买入行为与价格偏离内在价值呈正相关。然而,羊群卖出行为与价格偏离没有显著关系。此外,我们的研究结果还证明,共同基金的羊群买入行为会刺激其他市场参与者产生类似的交易情绪,并助长市场泡沫的形成,而羊群卖出行为则会促使平衡交易,从而减轻价格偏离的影响。

Fraud in financial statements can have an impact on the accuracy and reliability of the use of financial statements, including affecting the amount of tax, fines paid, and the audit process. This study aims to analyze the effect of pressure, arrogance and collusion on financial statement fraud and the role of income tax rates as a moderating variable in non-financial companies listed on the Indonesia Stock Exchange in 2020-2022. The data in this study consisted of 207 research observations determined using purposive sampling method. Data collection was conducted through document analysis, using annual financial reports and annual reports. The analytical technique employed was regression analysis, moderated by Eviews. The study commenced with a descriptive statistical analysis, followed by an examination of the classical assumptions, including multicollinearity and heteroskedasticity. Finally, an analysis of moderated regression was conducted. The results of the regression analysis indicated that pressure, arrogance, and collusion were found to influence financial statement fraud. The moderated regression analysis demonstrated that the income tax rate was capable of moderating the influence of pressure, arrogance, and collusion on financial statement fraud. The theoretical implications of this study offer a novel perspective on the moderating effect of income tax rates on the relationship between pressure, arrogance and collusion and financial statement fraud. This study is of practical value and provides information that can inform decision-making for stakeholders.
财务报表舞弊会对财务报表使用的准确性和可靠性产生影响,包括影响纳税额、支付的罚款以及审计过程。本研究旨在分析压力、傲慢和串通对财务报表舞弊的影响,以及所得税率作为调节变量在 2020-2022 年印尼证券交易所非金融类上市公司中的作用。本研究的数据包括采用目的性抽样方法确定的 207 个研究观察点。数据收集是通过年度财务报告和年度报告的文档分析进行的。采用的分析技术是回归分析,由 Eviews 进行调节。研究首先进行了描述性统计分析,然后检查了经典假设,包括多重共线性和异方差性。最后,进行了调节回归分析。回归分析的结果表明,压力、傲慢和串通被认为会影响财务报表舞弊。调节回归分析表明,所得税率能够调节压力、傲慢和串通对财务报表舞弊的影响。本研究的理论意义为所得税率对压力、傲慢和串通与财务报表舞弊之间关系的调节作用提供了一个新的视角。本研究具有实用价值,可为利益相关者的决策提供参考信息。

The purpose of the study was to investigate the effect of industry extension service projects on the performance of micro and small enterprises. Thus, the study utilized an explanatory and descriptive research design to achieve the objectives of the research. The study targeted MSEs that had been in operation for more than two years at the time of the study. The research had a total population of 606 MSEs, out of which a sample size of 241 operators was realized using Taro Yamane’s formula. Thus, a stratified sampling technique and simple random sampling were employed to select representative samples. Beside, primary and secondary data were used in the study. The analysis was conducted using SPSS version 20 on 223 fully responded questionnaires. The data was analyzed using descriptive and inferential statistics. In addition to this, correlation and regression models were used to analyze the variables of the study. The finding proved that IESP support provided by TVET trainers to MSEs was not adequate. Regression analysis indicated that entrepreneurship, technology, kaizen, and technical skill support had a positive and significant relationship with the performance of MSEs. Thus, it is recommended that the TVET College should provide regular industry extension service support to MSEs through four packages.
本研究的目的是调查行业推广服务项目对小微企业绩效的影响。因此,本研究采用了解释性和描述性研究设计来实现研究目标。研究对象是研究时已运营两年以上的微型企业。研究的总样本量为 606 家微型企业,其中 241 家经营者的样本量是根据山根太郎的公式计算得出的。因此,采用了分层抽样技术和简单随机抽样来选择具有代表性的样本。此外,研究还使用了第一手数据和第二手数据。研究使用 SPSS 20 版对 223 份完整回答的问卷进行了分析。数据分析采用了描述性和推论性统计方法。此外,还使用了相关和回归模型来分析研究变量。研究结果证明,职业技术教育与培训培训师为微型企业提供的 IESP 支持并不充分。回归分析表明,创业精神、技术、改善和技术技能支持与微型企业的绩效有显著的正相关关系。因此,建议职业技术教育与培训学院通过四种套餐为微型企业提供定期的行业推广服务支持。

Linking and Delinking Aspects of Economic Growth and Employment in the Indian Economy: Granger Causality Approach 印度经济中经济增长与就业之间的联系与脱钩:格兰杰因果关系方法
Pub Date : 2024-04-02 DOI: 10.11648/j.ijebo.20241201.12

The purpose of this paper is to provide an overview of various economic growth and employment approaches that have been popular throughout economic history, with a focus on linking and delinking aspects of GDP and employment in the Indian economy. The semi-log quadratic model was used for the trends of GDP and employment across the selected countries. For the determination of the linkages between the variables, the Granger causality test promulgated by Engel and Granger (1987), and the maximum likelihood-based technique of Johansen and Julius (1990) and Johansen (1992) were used in the study. The results found that employment and GDP are two different aspects of an economy not only in the Indian economy but across the majority of the world economies. The results of model specification proved the presence of both long-run and short-run relationships between GDP and employment by the Johansen co-integration test in the Indian economy over the period. It has been found that the increase in GDP is negatively influencing the employment level by the VECM model as a 1 per cent increase in GDP results in 0.28 per cent of job losses in the Indian economy. This study aims to provide an overview of several approaches to economic growth and employment that have been popular throughout economic history up to the present, with an emphasis on linking and delinking aspects of economic growth and employment. In the context of an economy, economic growth and employment are two distinct aspects that should be tackled with separate economic strategies.
本文旨在概述经济史上流行的各种经济增长和就业方法,重点关注印度经济中国内生产总值和就业之间的联系和脱钩。本文采用半对数二次模型来研究选定国家的国内生产总值和就业趋势。为确定变量之间的联系,研究采用了 Engel 和 Granger(1987 年)颁布的格兰杰因果检验法,以及 Johansen 和 Julius(1990 年)和 Johansen(1992 年)基于最大似然法的技术。研究结果发现,就业和 GDP 是经济的两个不同方面,不仅在印度经济中如此,在世界大多数经济体中也是如此。通过 Johansen 协整检验,模型规范的结果证明印度经济在这一时期的国内生产总值和就业之间存在长期和短期关系。通过 VECM 模型发现,国内生产总值的增长对就业水平有负面影响,因为国内生产总值每增长 1%,印度经济中的就业岗位就会减少 0.28%。本研究旨在概述经济史上流行至今的几种经济增长和就业方法,重点是经济增长和就业之间的联系和脱钩。就一个经济体而言,经济增长和就业是两个截然不同的方面,应分别采用不同的经济战略加以解决。

The Impact of COVID-19 Epidemic on the Hedging Islamic and Conventional Stock Markets with Financial Assets COVID-19 疫情对以金融资产对冲伊斯兰股市和传统股市的影响
Pub Date : 2024-04-02 DOI: 10.11648/j.ijebo.20241201.11

This study investigates optimal hedging ratios for Islamic and conventional stock markets during the COVID-19 pandemic using the DCC (Dynamic Conditional Correlation), ADCC (Asymmetric Dynamic Conditional Correlation), and GO-GARCH (Generalized Orthogonal GARCH) models. The effectiveness of various financial assets as hedges is evaluated, and findings indicate that the DJCOM (Dow Jones Commodity), VISTOXX (Euro STOXX 50 Volatility Index), and VIX (Chicago Board Options Exchange Volatility Index) indices exhibit superior effectiveness across both market types, particularly DJCOM showing exceptional performance during the COVID-19 period. The hedging analysis indicates that the hedge ratios vary and depend upon the hedge instrument included in the portfolio. Furthermore, the empirical results indicate that the global impact of the pandemic diminishes the viability of one of the six assets as a safe haven instrument. In conclusion, these findings provide valuable insights for investors and portfolio managers aiming to utilize Gold, Brent, VISTOXX, VIX, CDS (Credit Default Swap), and DJCOM for portfolio rebalancing to mitigate risks associated with volatile Islamic and conventional stock returns. These conclusions contribute significantly to helping investors adjust their investment strategies more effectively and adapt to changing market conditions.
本研究采用 DCC(动态条件相关性)、ADCC(非对称动态条件相关性)和 GO-GARCH(广义正交 GARCH)模型,对 COVID-19 大流行期间伊斯兰股市和传统股市的最佳对冲比率进行了研究。结果表明,DJCOM(道琼斯商品指数)、VISTOXX(欧洲斯托克 50 波动率指数)和 VIX(芝加哥期权交易所波动率指数)指数在两种市场类型中都表现出卓越的有效性,尤其是 DJCOM 在 COVID-19 期间的表现尤为突出。对冲分析表明,对冲比率各不相同,取决于投资组合中包含的对冲工具。此外,实证结果表明,大流行病的全球影响削弱了六种资产之一作为避险工具的可行性。总之,这些研究结果为投资者和投资组合经理提供了宝贵的见解,他们可以利用黄金、布伦特、VISTOXX、VIX、CDS(信用违约掉期)和 DJCOM 进行投资组合再平衡,以降低与伊斯兰和传统股票收益波动相关的风险。这些结论有助于帮助投资者更有效地调整投资策略,适应不断变化的市场条件。

Investing in the Pioneering Varieties as an Agreement to Attaining Economic Take-off on Smallholder Seed Firms in West Africa 投资于先驱品种是西非小农种子公司实现经济起飞的一项协议

Farmers everywhere depend on access to good quality seed, which is fundamental to their crop production systems. Most governments have made significant investments in strengthening national agricultural production capacities, yet farmers in developing countries still face difficulties in accessing the quality seed of the varieties that they require. Guaranteeing farmers’ access to quality seed can only be achieved through a viable seed supply system that can multiply and distribute seeds, which have been produced or preserved. This is better achieved by the private sector, but medium- to large-scale international seed companies concentrate on high-value crops and avoid dealing in the self-pollinating, open-pollinating and vegetative-propagated varieties on which most smallholder farmers depend for their food security as the biology of these crops makes it easy for farmers to keep their seeds for several seasons. However, smallholders are often seen as the driving force of economic growth, poverty reduction and food security. This is also true for smallholder seed enterprises, which, in the absence of large companies, provide a valid alternative for the production and distribution of food security crops. This paper reviews case studies on smallholder seed enterprise in Côte d’Ivoire, as well as relevant world literature in order to identify key issues that facilitate or constrain the development of the seed sector. The final section provides some guidelines on policy design and implementation to promote the development of sustainable seed enterprises at different stages in the evolution of national seed sectors. It provides examples of good practices and hence seeks to assist governments in identifying ways in which they can support the development of smallholder seed enterprises that will provide the most appropriate varieties to smallholder farmers in their efforts to boost food production.
优质种子是农作物生产系统的基础,世界各地的农民都依赖于获得优质种子。大多数国家的政府都在加强本国农业生产能力方面进行了大量投资,但发展中国家的农民在获得所需的优质种子方面仍然面临困难。只有通过可行的种子供应系统,对生产或保存的种子进行繁殖和分发,才能保证农民获得优质种子。私营部门能更好地实现这一目标,但大中型国际种子公司集中经营高价值作物,避免经营大多数小农赖以生存的自花授粉、开放授粉和无性繁殖品种,因为这些作物的生物学特性使农民很容易将种子保存数季。然而,小农往往被视为经济增长、减贫和粮食安全的推动力。小农种子企业也是如此,在没有大公司的情况下,它们为粮食安全作物的生产和销售提供了一种有效的选择。本文回顾了科特迪瓦小农种子企业的案例研究以及相关的世界文献,以确定促进或制约种子行业发展的关键问题。最后一节提供了在国家种子部门发展的不同阶段促进可持续种子企业发展的政策设计和实施指南。它提供了良好做法的范例,从而寻求帮助各国政府确定支持小农种子企业发展的方式,为小农提供最合适的品种,努力提高粮食产量。

The primary motive of this paper was to investigate the impact of Foreign Direct Investment on economic growth of Nigeria from 1985 to 2022. Ex – post facto research design was carefully carried out; annual time series data were extracted from Central Bank of Nigeria Statistical Bulletin of 2021 and World Development Indicator. Real Gross Domestic Product (RGDP) was used as the dependent variable proxy for economic growth. Foreign Direct Investment (FDI), Exchange Rate (EXCR), Trade Openness (TOPN) and Inflation (INF) all denoted for explanatory variables of the study. The estimated coefficients of the variables under study displayed that all the variables are integrated of the same order 1(1) exception of Foreign Direct Investment which was integrated of order 1(0). The bound test conducted showed that there is proof of the presence of a long run correlation among the variables used while the causality test clearly showed that FDI granger causes economic growth in Nigeria under review. Other diagnostic tests seen in this paper are unit root test, descriptive statistics, correlation coefficient matrix, Cointegration test and test of Normality respectively, and they long-established the validity and reliability of the model used. Based on the inferential results revealed by the research work, the paper came up with recommendation that government should improve the investment climate for both domestic and foreign investors through adequate infrastructural development, soft loans and tax holidays.
本文的主要动机是研究 1985 年至 2022 年期间外国直接投资对尼日利亚经济增长的影响。本文采用了谨慎的事后研究设计;从尼日利亚中央银行 2021 年统计公报和世界发展指标中提取了年度时间序列数据。实际国内生产总值(RGDP)被用作经济增长的因变量。外商直接投资(FDI)、汇率(EXCR)、贸易开放度(TOPN)和通货膨胀率(INF)均作为研究的解释变量。研究变量的估计系数显示,除了外商直接投资的综合阶数为 1(0)外,其他所有变量的综合阶数均为 1(1)。所进行的约束检验表明,所使用的变量之间存在长期相关性,而因果检验则清楚地表明,外国直接投资是尼日利亚经济增长的格兰杰原因。本文中的其他诊断测试包括单位根测试、描述性统计、相关系数矩阵、协整性测试和正态性测试,它们分别证明了所使用模型的有效性和可靠性。根据研究工作所揭示的推论结果,本文提出了建议,即政府应通过适当的基础设施建设、软贷款和免税期来改善国内外投资者的投资环境。

Ex – post facto research design was carefully carried out; annual time series data were extracted from Central Bank of Nigeria Statistical Bulletin of 2021 and World Development Indicator. Real Gross Domestic Product (RGDP) was used as the dependent variable proxy for economic growth. Foreign Direct Investment (FDI), Exchange Rate (EXCR), Trade Openness (TOPN) and Inflation (INF) all denoted for explanatory variables of the study. The estimated coefficients of the variables under study displayed that all the variables are integrated of the same order 1(1) exception of Foreign Direct Investment which was integrated of order 1(0). The bound test conducted showed that there is proof of the presence of a long run correlation among the variables used while the causality test clearly showed that FDI granger causes economic growth in Nigeria under review. Other diagnostic tests seen in this paper are unit root test, descriptive statistics, correlation coefficient matrix, Cointegration test and test of Normality respectively, and they long-established the validity and reliability of the model used.
