This paper examines the function of accruals in measuring quarterly firm performance. We show that operating accruals play a pronounced role in offsetting quarterly cash flow fluctuations and that this timing role is much stronger than concluded based on annual measurements in the recent literature. A fundamental driver of this timing role of accruals is the significant seasonal variation in operating cash flows, which is determined by the interaction between sales seasonality and working capital policies. We further find that the seasonality in cash flows and the offsetting role of accruals have declined over time. We link this trend to international diversification, trends in the importance and seasonality of retail sales, zero-inventory firms, market power, and the rise in supply chain finance.
本文考察了应计项目在衡量季度企业绩效中的作用。我们表明,经营应计项目在抵消季度现金流量波动方面发挥着明显的作用,并且这种定时作用比最近文献中基于年度测量得出的结论要强得多。应计项目的这种时间作用的一个基本驱动因素是经营性现金流量的显著季节性变化,这是由销售季节性和营运资金政策之间的相互作用决定的。我们进一步发现,现金流量的季节性和应计项目的抵消作用随着时间的推移而下降。我们将这一趋势与国际多元化、零售销售的重要性和季节性趋势、零库存公司、市场力量以及供应链金融的兴起联系起来。

As markets replace contractual liquidity providers (designated market makers; DMMs) with voluntary liquidity provision through cutting-edge technology, we investigate how this affects price discovery. Research suggests that endogenous liquidity provision is not always optimal. We investigate how DMMs affect the incorporation of earnings news into prices. Using a regression discontinuity design, we show that increased DMM participation facilitates earnings news discovery—lower JUMP, lower Synchronicity, and higher Future Earnings Response Coefficient. Greater DMM participation associates with improved liquidity, and induces greater informed trading as evidenced by more short selling on negative news and increased EDGAR and Bloomberg search activity before earnings announcements. Our results highlight an important and hitherto overlooked effect of modern technology on processing earnings information.
随着市场通过尖端技术以自愿流动性提供取代合同流动性提供者(指定做市商;dmm),我们研究了这对价格发现的影响。研究表明,内生流动性供应并不总是最优的。我们研究了dmm如何影响收益新闻纳入价格。使用回归不连续设计,我们发现增加的DMM参与有助于收益新闻发现-较低的跳跃,较低的同步性和较高的未来收益响应系数。更大的DMM参与与流动性的改善有关,并诱导更多的知情交易,这可以从负面新闻的更多卖空和收益公告前EDGAR和彭博搜索活动的增加中得到证明。我们的研究结果突出了现代技术对盈余信息处理的重要和迄今为止被忽视的影响。

Purpose: Taxes play a critical role for most governments around the world in funding investments in capital, infrastructure and the delivery of essential services. The study therefore sought to examine the effect of trade openness and agriculture on tax revenue performance in Kenya. Methodology: The study adopted correlational research design, Vector Error Correction Model (VECM) mechanism and Granger causality test to establish the relationship between the study variables. The choice of the VECM was influenced by its ability to estimate both short run and long run relationships. The theoretical framework of the study followed Heller’s neoclassical maximization utility approach. Annual time series data for the study were sourced from the World Bank Development Indicators for the period 1980-2020. Results: The study findings established that in the long-run agriculture share (-0.64, t-statistics = 14.57) and trade openness (-0.08, t-statistics = 3.88) have negative and significant effect on tax revenue performance in Kenya. The Pairwise Granger Causality test results indicated unidirectional causality running from tax revenue performance to trade openness. This suggests that tax rates have effect on trade openness in Kenya. Unique Contribution to Theory, Policy and Practice: The study adds to literature by proving the Arthur’s Laffer curve theory which advocates for lowering tax rates in order to boost productivity and encourage expansion of corporation. The findings of the study may provide the National Treasury with foundation for policy formulation and analytical framework for estimating the associated tax revenue with variables under consideration in this study. The study may be of importance to KRA in determining appropriate tax rates that are favorable in boosting revenue mobilization.
目的:对世界上大多数政府来说,税收在为资本、基础设施和提供基本服务的投资提供资金方面发挥着关键作用。因此,该研究试图检验贸易开放和农业对肯尼亚税收绩效的影响。方法:采用相关研究设计、向量误差修正模型(Vector Error Correction Model, VECM)机制和格兰杰因果检验来建立研究变量之间的关系。VECM的选择受到其评估短期和长期关系的能力的影响。本研究的理论框架遵循了海勒的新古典主义效用最大化方法。该研究的年度时间序列数据来自世界银行1980-2020年期间的发展指标。结果:研究发现,从长期来看,农业份额(-0.64,t统计量= 14.57)和贸易开放(-0.08,t统计量= 3.88)对肯尼亚税收绩效具有显著的负向影响。两两格兰杰因果检验结果表明,税收绩效与贸易开放之间存在单向因果关系。这表明税率对肯尼亚的贸易开放程度有影响。 对理论、政策和实践的独特贡献:该研究通过证明亚瑟·拉弗曲线理论增加了文献,该理论主张降低税率以提高生产率并鼓励公司扩张。研究结果可为国家财政部提供政策制定的基础,并提供分析框架,以估计本研究所考虑的变量的相关税收。这项研究可能对KRA确定有利于促进收入调动的适当税率具有重要意义。

Purpose: This study examined the performance of food and beverage industries in Tanzania in terms of productive and technical efficiency. The specific objectives of the study were to evaluate the productive efficiency performance of food and beverage industries in Tanzania, to determine the level and trend of efficiency of food and beverage of food and beverage industry in Tanzania, and to assess the levels of productive efficiency performance in the food and beverage subsectors in Tanzania Methodology: The study used secondary data to achieve its objectives. The study employed a Panel data analysis technique using 40 companies in the manufacturing sector over a period of three years, 2018-2020. A stochastic frontier production model was applied using a linearized Translog production function to determine the performance elasticity coefficients of inputs and technical efficiency. The study used production theory advanced by Koutsoyiannis (1979) to explain the relatonship between input and output factors. Findings: One of the key findings was that the level and trend of efficiency in food and beverage industry demonstrated an upward trend for the period between 2018 and 2020 as evidenced by the changes in average in both food and beverage sub-sector which grew from 0.776 in 2018 to 0.7557 in 2019 and finally to 0.7746 in 2020. Another finding of the study was that, the individual productive efficiency distribution between food and beverage sub-sector revealed that beverage sub-sector performs much better than food sub-sectors, with an average technical efficiency of 77.85% and 81.36% for both food and beverage sub-sectors, respectively. Unique Contribution to Theory, Practice and Policy: The study’s unique contributions to theory include its assessment of efficiency levels, analysis of efficiency trends, and exploration of sector-specific variations. Its practical contributions encompass policy recommendations, guidance on modernization and technology adoption, and the importance of skills development and export promotion. These insights have direct implications for policymakers, industry stakeholders, and practitioners in Tanzania's food and beverage sector, aiding in the formulation of effective strategies to enhance efficiency and competitiveness. The study recommends that the government and other stakeholders comes up with policy reforms to address the underlying factors contributing to the underutilization of each firm’s production capacity. This includes reforming the input market in the manufacturing sector in order to increase the level of efficiency to 100%. There should be establishment of an efficient marketing mechanism that reduces the involvement of many parties in the supply chain and hence high transaction costs.

Effect of Per Capita Income on Youth Unemployment in Kenya 肯尼亚人均收入对青年失业的影响
Q4 ECONOMICS Pub Date : 2023-09-23 DOI: 10.47604/ijecon.2118
Jerry Okuom, Nelson Obange, Scholastica Odhiambo
Purpose: The objective was to determine the effect of per capita income on youth unemployment in Kenya. Methodology: The study was anchored on Okun’s law, which predicts a 1% drop in employment from a 2% drop in GDP. The study used the World Bank Database’s quantitative time series data from 1991–2021. The choice of the ARDL was based on the ability of the model to give long-run and short-run analyses of stationary and non-stationary variables. Pre-estimation procedures and diagnostics tests were used to determine the stability of the model. Findings: Findings revealed a significant negative relationship between per capita income (-0.3666, p = 0.013) and youth unemployment in the long-run. The speed of adjustment (-0.89999, p = 0.0001) from the short-run to the long-run is evident. Unique Contribution to Theory, Practice and Policy: This study may help academicians develop their knowledge of youth unemployment. It may increase understanding of per capita income as an indicator of growth and its application in Okun’s law. The Salaries and Remuneration Commission (SRC) may benefit from this study by creating better packages of salaries, allowances, and mortgages that may attract and improve the standard of living of Kenyan youth. The Public Service Board (PSB) may establish youth-friendly offices to motivate youth to stay in the labour force. Moreover, this study may guide the State Department for Youth Affairs to promote youth employment and increase labour productivity in Kenya. The State Department of Gender may use the study in gender mainstreaming and gender policy management. Policymakers will assess the effectiveness of the curriculum in preparing youth for the job market. An increase in labour productivity will result from increasing youth employment.
目的:目的是确定肯尼亚人均收入对青年失业的影响。 研究方法:该研究以奥肯定律为基础,该定律预测GDP下降2%会导致就业下降1%。该研究使用了世界银行数据库1991-2021年的定量时间序列数据。ARDL的选择是基于模型对平稳和非平稳变量进行长期和短期分析的能力。使用预估计程序和诊断测试来确定模型的稳定性。 研究发现:长期来看,人均收入(-0.3666,p = 0.013)与青年失业率呈显著负相关。从短期到长期的调整速度(-0.89999,p = 0.0001)是明显的。对理论、实践和政策的独特贡献:本研究有助于学术界对青年失业问题的认识。它可以增进对人均收入作为经济增长指标及其在奥肯定律中的应用的理解。工资和薪酬委员会(SRC)可能会从这项研究中受益,通过制定更好的工资、津贴和抵押贷款一揽子计划,吸引和提高肯尼亚年轻人的生活水平。公务员事务局可设立青年友好办事处,鼓励青年留在劳动大军。此外,这项研究可以指导国家青年事务部促进青年就业和提高肯尼亚的劳动生产率。国务院性别平等司可将该研究用于性别平等主流化和性别平等政策管理。决策者将评估课程在帮助年轻人为就业市场做好准备方面的有效性。增加青年就业将导致劳动生产率的提高。

The Impact of Artificial Intelligence (AI) on Customer Relationship Management: A Qualitative Study 人工智能(AI)对客户关系管理的影响:定性研究
Q4 ECONOMICS Pub Date : 2023-09-17 DOI: 10.34104/ijma.023.0074090
Ever since the commercialization of the Internet in the '90s, technology has been evolving faster than ever with the advent of cloud computing, social media, ubiquitous mobile devices, the Internet of Things (IoT), blockchain, and more. A staggering number of three billion internet users, five billion mobile users, and six billion devices are now connected through this massive global network of networks, facilitating customer information exchange and interaction never before seen in history. Driven by recent technological advances in computing power, big data, high-speed internet connection, and easier access to models built with advanced algorithms, Artificial Intelligence (AI) is the next wave of innovation, which has already come into widespread awareness in the consumer world with the emergence of virtual assistants and chatbots (e.g., Amazon's Alexa, Apple's Siri, Google's Assistant), image recognition (e.g., Facebook Photos, Google ImageNet), personalized recommendations (e.g., Netflix, Amazon) and autonomous driving (e.g., Tesla, Google Waymo). This qualitative research study intends to learn about the impact of AI on customer relationship management (CRM), specifically in the area of customer service of problem resolution. Most prior research focuses on the AI technologies leveraged in CRM systems, such as machine learning, natural language processing, voice recognition, chatbots, data analytics, and cloud infrastructure. Few extant studies have used a qualitative research methodology to gather data from industry experts to truly understand the impact of AI technologies on customer relationship management, especially in the area of customer service and problem resolution. This study aims to fill this research gap.

A staggering number of three billion internet users, five billion mobile users, and six billion devices are now connected through this massive global network of networks, facilitating customer information exchange and interaction never before seen in history. Driven by recent technological advances in computing power, big data, high-speed internet connection, and easier access to models built with advanced algorithms, Artificial Intelligence (AI) is the next wave of innovation, which has already come into widespread awareness in the consumer world with the emergence of virtual assistants and chatbots (e.g., Amazon's Alexa, Apple's Siri, Google's Assistant), image recognition (e.g., Facebook Photos, Google ImageNet), personalized recommendations (e.g., Netflix, Amazon) and autonomous driving (e.g., Tesla, Google Waymo). This qualitative research study intends to learn about the impact of AI on customer relationship management (CRM), specifically in the area of customer service of problem resolution. Most prior research focuses on the AI technologies leveraged in CRM systems, such as machine learning, natural language processing, voice recognition, chatbots, data analytics, and cloud infrastructure. Few extant studies have used a qualitative research methodology to gather data from industry experts to truly understand the impact of AI technologies on customer relationship management, especially in the area of customer service and problem resolution. This study aims to fill this research gap. This research contributes to the literature on AI in the context of CRM and is of value to both academics and practitioners as it provides a detailed analysis and documentation of the impact of AI on the customer service domain.","PeriodicalId":42721,"journal":{"name":"International Journal of Economics Management and Accounting","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135303865","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using the Z-score to analyze the Financial Stability of Conventional Commercial Banks in Bangladesh 运用Z-score分析孟加拉国传统商业银行的金融稳定性
IF 1.2 Q4 ECONOMICS Pub Date : 2023-08-08 DOI: 10.34104/ijma.023.0066073
This paper aims to measure and identify the determinants of financial stability of conventional commercial banks of Bangladesh listed on the Dhaka Stock Exchange. In the first step, the researcher calculates an accounting-based Z-score to measure the financial stability of the 23 sample banks over the period 2013-2022. In the second phase of the study, panel data regression analysis is conducted to identify the bank-specific determinants of financial stability. The exogenous variables include return on asset, income diversity, bank size, non-performing loan liquidity, capital adequacy, and management efficiency. The endogenous variable is the financial stability measured by z-score. The study provides empirical evidence of the bank-specific factors affecting the solvency of conventional commercial banks in Bangladesh.

Domestic investment is a key component of the economic growth of any country. In recent years, the growth of domestic investment has not been optimistic. This study aims at analyzing the factors affecting domestic investment in Tanzania. Time-series data of the 1980- 2020 period is used to empirically analyse the performance of the domestic investment. The study applies the Error Correction Model (ECM) to estimate the parameters. Factors affecting domestic investment in Tanzania are critically analysed. The factors influencing domestic investment includes money supply, interest rate, savings rate, and government expenditure. The regression results of this study show that government expenditure is insignificant in influencing domestic investment while money supply, interest rate, and savings rate are statistically significant. To this end, measures that influence domestic investment are indeed called for, implying a need for policies that can control interest rates, savings rates, and money supply . This paper recommends putting in place a conducive environment that could accelerate financial intermediation and domestic savings mobilization in order to improve domestic investment. Furthermore, the study suggests the encouragement of investment incentives and the establishment of vibrant investment promotion agencies.
国内投资是任何国家经济增长的关键组成部分。近年来,国内投资的增长并不乐观。本研究旨在分析影响坦桑尼亚国内投资的因素。本文采用1980- 2020年的时间序列数据对国内投资绩效进行了实证分析。本文采用误差修正模型(ECM)对参数进行估计。对影响坦桑尼亚国内投资的因素进行了批判性分析。影响国内投资的因素包括货币供应量、利率、储蓄率和政府支出。本研究的回归结果显示,政府支出对国内投资的影响不显著,而货币供应量、利率和储蓄率对国内投资的影响具有统计学意义。为此,确实需要影响国内投资的措施,这意味着需要能够控制利率、储蓄率和货币供应量的政策。本文建议建立一个有利的环境,加速金融中介和国内储蓄的动员,以改善国内投资。此外,研究建议鼓励投资激励和建立充满活力的投资促进机构。
