Abstract The bioeconomy is an area that encompasses more economic activities and is environmentally friendly and sustainable. Bioeconomy contributes to the economic development of a state by creating new jobs, expanding the business environment and making activities more efficient. In this context, the bioeconomy is an element of economic development that helps the Central and Eastern European countries (CEECs) to bridge the gap with the other countries in the west of the continent. The article aims to analyze the grouping of CEECs based on indicators specific to the bioeconomy, to highlight similarities or discrepancies between them. Moreover, we conduct this study in order to identify Romania’s position among CEECs in terms of specific bioeconomy indicators. The study is based on the European Commission’s Joint Research Center database for the bioeconomy indexes for these particular regions. We employed a hierarchical cluster method using SPSS software. The sample consisted of the 11 CEEC Member States (MS) of the European Union (EU), and the period under review was between 2008 and 2019. The research indicators included turnover, number of workers, apparent labour productivity, and added value. The results show that Slovakia, Croatia and Romania form individual groups at an iteration level between 0 and 15, indicating significant discrepancies between countries in the region. The novelty of the research derives from the fact that there are no previous analyses that compare Romania’s status with other CEECs from the perspective of bioeconomy. Therefore, the paper can contribute to the implementation by the Romanian authorities of a set of measures necessary to develop the strategy dedicated to the bioeconomy based on good practices from the other CEECs.
摘要生物经济是一个包含更多经济活动的领域,具有环境友好性和可持续性。生物经济通过创造新的就业机会、扩大商业环境和提高活动效率来促进一个国家的经济发展。在这种背景下,生物经济是经济发展的一个要素,可以帮助中欧和东欧国家(CEECs)弥合与欧洲大陆西部其他国家的差距。本文旨在根据生物经济的具体指标分析中东欧国家的分组,以突出它们之间的相似或差异。此外,我们进行这项研究是为了确定罗马尼亚在中东欧国家中具体生物经济指标方面的地位。这项研究是基于欧盟委员会联合研究中心关于这些特定地区生物经济指数的数据库。采用SPSS软件进行分层聚类分析。样本包括欧盟(EU)的11个中东欧成员国(MS),审查期间为2008年至2019年。研究指标包括营业额、工人人数、表观劳动生产率和增加值。结果表明,斯洛伐克、克罗地亚和罗马尼亚在0到15之间的迭代水平上形成单独的群体,表明该地区国家之间存在显著差异。这项研究的新颖之处在于,以前没有从生物经济的角度将罗马尼亚与其他中东欧国家的地位进行比较的分析。因此,本文可以帮助罗马尼亚当局实施一套必要的措施,以其他中东欧国家的良好做法为基础,制定致力于生物经济的战略。

Abstract The current labour market is at a crossroads: on one hand, there are challenges triggered by technological pressures and perks, aiming at a greener, more sustainable and resilient economic growth, and on the other hand, there are the changes and tensions generated by the current institutional frameworks, that show delays in mitigating the apparent “de-socialising” of this market. The pandemic paradox of 2019-2021 has emphasized several vulnerabilities particularly of economic-institutional nature. Traditional theories seem unsatisfactory while unorthodox approaches are faced with hesitancy. The present paper intends to present a brief analysis of labour market’s challenges in the immediate future by proposing a mixed approach combining traditional statistical-data with a less employed institutional framework. The approach is substantiated and constructed by the structural and cognitive features that the new labour market would require. It suggests a possible way for considering the aims of the Green Deal, the vulnerabilities highlighted by the pandemic and by the recent conflict in the immediate proximity of the EU-27. All these developments bring about changes for several socio-economic categories, rendering most of them vulnerable. The split between “essential” and “non-essential” economic activities, platform work and the gig economy hint to increased relevance of the three types of intangible capital: human, social and intellectual. This will require an integrating perspective, if severe economic and social effects are to be avoided in the immediate future. The model we propose aims to show how, by taking account of the human, social and intellectual capital, better policies can be developed as regards labour market efficiency and efficacy.
摘要当前的劳动力市场正处于十字路口:一方面,技术压力和福利引发了挑战,旨在实现更绿色、更可持续和更有弹性的经济增长,另一方面,当前的制度框架产生了变化和紧张局势,这表明在缓解该市场明显的“去社会化”方面出现了延误。2019-2021年的疫情悖论强调了几个脆弱性,特别是经济制度性质的脆弱性。传统的理论似乎并不令人满意,而非正统的方法则面临着犹豫。本文件旨在通过提出一种将传统统计数据与较少使用的制度框架相结合的混合方法,简要分析劳动力市场在不久的将来面临的挑战。这种方法是由新劳动力市场所需的结构和认知特征所证实和构建的。它提出了一种可能的方式来考虑绿色协议的目标、新冠疫情和欧盟27国附近最近的冲突所突显的脆弱性。所有这些发展都给几个社会经济类别带来了变化,使其中大多数人处于弱势。“必要”和“非必要”经济活动、平台工作和零工经济之间的划分表明,人力、社会和智力这三类无形资本的相关性增加。如果要在不久的将来避免严重的经济和社会影响,这将需要一个综合的视角。我们提出的模型旨在表明,通过考虑人力、社会和知识资本,如何在劳动力市场效率和效力方面制定更好的政策。

Abstract The paper provides an explanation of some terms used in the field of business and accounting when it comes to the implementation of artificial intelligence in these areas. The development of artificial intelligence began in the 1950s, of course at first with small steps, but in the last two years it is developing at the speed of light. In order to understand the algorithms with which artificial intelligence works, I chose to outline the work machine learning, big data, neural networks. The benefits of business and accounting can be observed in easing and reducing the time in data processing. From the applications used in accounting we chose the presentation of AlphaSense, TensorFlow, Kensho, Clarifai. If we think about accounting, that until now it involved archiving on paper, blockchain and cloud accounting intervene towards our help which, thanks to distributed accounting technology, eliminate the need to enter accounting information in several databases.
摘要当涉及到人工智能在这些领域的实施时,本文对商业和会计领域中使用的一些术语进行了解释。人工智能的发展始于20世纪50年代,当然一开始只是一小步,但在过去的两年里,它正在以光速发展。为了理解人工智能的工作算法,我选择概述机器学习、大数据、神经网络等工作。商业和会计的好处可以从简化和减少数据处理时间中看出。从会计中使用的应用程序中,我们选择了AlphaSense、TensorFlow、Kensho和Clarifai的表示。如果我们考虑会计,到目前为止,它涉及纸面归档、区块链和云会计对我们的帮助进行干预,这得益于分布式会计技术,消除了在多个数据库中输入会计信息的需要。

Abstract Social media has positioned itself as one of the most effective and efficient engines of disseminating both social and business information throughout the world. The purpose of this study was to establish the role of social media in enhancing business activities of SMEs in Gwanda town. The study used a qualitative research methodology where 23 participants who were drawn from 7 organizations were interviewed using face to face interviews. A combination of purposive and convenience sampling techniques was used to select the 7 organizations and 23 participants who participated in the study. Thematic data analysis was utilized to analyze the data that was solicited using a 14 item interview guide. The study established that to a larger extent social media is a business enabler. Social media improves the effectiveness and efficiency of organizations by promoting an easy flow of information within departments and with external stakeholders. Social media increases the profitability and the general performance of SMEs and directly and indirectly reduces operational costs. Social media helps managers to keep workers updated about the developments taking place in the organization. It was also found that to a lesser extent social media hinders the performance and growth of organizations since it can easily be abused by employees who spend most of the business time chatting and conversing with friends and relatives on issues that are not related to work.
摘要社交媒体已将自己定位为在世界各地传播社交和商业信息的最有效和最高效的引擎之一。本研究的目的是确定社交媒体在促进瓜达镇中小企业商业活动中的作用。该研究采用了定性研究方法,对来自7个组织的23名参与者进行了面对面访谈。采用目的性和方便性抽样技术相结合的方法选择了参与研究的7个组织和23名参与者。专题数据分析用于分析使用14项访谈指南征求的数据。该研究证实,在更大程度上,社交媒体是一种商业推动者。社交媒体通过促进部门内部和外部利益相关者之间的信息轻松流动,提高了组织的有效性和效率。社交媒体提高了中小企业的盈利能力和总体业绩,并直接和间接降低了运营成本。社交媒体有助于管理者让员工了解组织中的最新发展。研究还发现,社交媒体在较小程度上阻碍了组织的绩效和发展,因为它很容易被员工滥用,他们把大部分业务时间花在与朋友和亲戚就与工作无关的问题聊天和交谈上。

How Effective are Monetary Policy Tools in Controlling Inflation in Nigeria? An Empirical Investigation 尼日利亚货币政策工具在控制通货膨胀方面的效果如何?实证研究
Pub Date : 2022-12-01 DOI: 10.2478/tjeb-2022-0001

Abstract In applying the monetary policy in controlling inflation, the monetary authorities employ a mix of tools, which when varied, transfer their effects to the target outcome of inflation control. Despite monetary authorities having employed series of strategies including recently, inflation targeting, the Nigerian inflation rates have remained uncontrollable, thereby, suggesting that the question could, however, be of the effectiveness of tools being employed. This study thus, examines the effectiveness of monetary policy rates, treasury bills rates and liquidity ratio in controlling inflation in Nigeria using annual data covering the period between 1981 and 2019. Unlike most existing studies that employed a combination of policy tools and intermediate outcomes, this study employed only monetary policy tools in its analysis. Results obtained from the estimated ARDL (2, 2, 1, 2) model suggest that both in the long-run and short-run, monetary policy rates have insignificant impact on inflation rates, thus, implying that they have been ineffective in inflation control. More so, treasury bills rates were found to be effective only in the short-run as lagged treasury bills rates showed a significant negative impact on inflation in the short-run while liquidity ratio proved effective only in the long-run with an unfavourable effect on inflation control in the short-run. It is recommended, therefore, that the monetary authorities reduce the size of the informal financial system by strengthening the official financial system in a bid to make the monetary tools of choice more effective for inflation control.
摘要在实施货币政策控制通货膨胀时,货币当局采用了多种工具,这些工具在变化时会将其效果转化为通货膨胀控制的目标结果。尽管货币当局最近采取了一系列策略,包括通胀目标,但尼日利亚的通胀率仍然无法控制,这表明问题可能是所使用工具的有效性。因此,本研究利用1981年至2019年期间的年度数据,考察了货币政策利率、国债利率和流动性比率在控制尼日利亚通货膨胀方面的有效性。与大多数现有研究结合使用政策工具和中间结果不同,本研究在分析中只使用了货币政策工具。从估计的ARDL(2,2,1,2)模型中获得的结果表明,无论是从长期还是短期来看,货币政策利率对通货膨胀率的影响都不显著,这意味着它们在控制通货膨胀方面是无效的。更重要的是,国库券利率仅在短期内有效,因为滞后的国库券利率在短期内对通胀产生了显著的负面影响,而流动性比率仅在长期内有效,在短期内会对通胀控制产生不利影响。因此,建议货币当局通过加强官方金融系统来缩小非正规金融系统的规模,以使所选择的货币工具更有效地控制通货膨胀。

Income Shock and Coping Strategies of Government Workers in Southwest Nigeria: Evidence from the Survey Data 尼日利亚西南部政府工作人员的收入冲击与应对策略:来自调查数据的证据
Pub Date : 2022-12-01 DOI: 10.2478/tjeb-2022-0004

Abstract Consumers’ response to income shock have been a source of concern over the years. Unexpected negative income shock, such as nonpayment of salaries, or salary reduction may cause an individual to react differently. Coping may be easy if an individual is well-prepared and has fully insured coping strategies prior to the income shock, hence, a negative income loss would have less impact. Otherwise, an income shock could be deleterious and leave an individual vulnerable. Therefore, ability to cope during negative income shock is determined by consumers’ preparedness as well as the effectiveness and appropriateness of available coping strategies. This study, therefore, examines the coping mechanisms of government employees in southwest Nigeria during the unexpected nonpayment of salary between 2015 and 2018. Both quantitative and qualitative methods using a structured questionnaire and FDGs are employed. The data is analyzed using descriptive statistics and OLS methods. The findings suggest that durable and service goods are substituted for food consumption, while the impact of coping strategies varies across the states. Empirical results from the OLS show that workers use personal savings and credit-purchases to smooth-out consumption, borrow and reallocate resources from durables and service for food consumption. Education, spouse occupation and age also have a positive impact on consumption. Evaluation of the coping strategies indicates that they are insufficient to satisfy the needs of the workers during the shock. The study, therefore, recommends that governments should provide a flexible working environment, formulate a policy that will allow workers to diversify into businesses, provide business loans and encourage mandatory saving for uncertainty.
摘要多年来,消费者对收入冲击的反应一直备受关注。意外的负收入冲击,如不支付工资或减薪,可能会导致个人做出不同的反应。如果个人在收入冲击之前做好了充分的准备并有充分的应对策略,应对可能会很容易,因此,负收入损失的影响较小。否则,收入冲击可能是有害的,并使个人处于弱势。因此,应对负收入冲击的能力取决于消费者的准备情况以及可用应对策略的有效性和适当性。因此,本研究考察了尼日利亚西南部政府雇员在2015年至2018年间意外拖欠工资期间的应对机制。采用定量和定性方法,使用结构化问卷和FDG。使用描述性统计和OLS方法对数据进行分析。研究结果表明,耐用品和服务品取代了食品消费,而应对策略的影响因州而异。OLS的实证结果表明,工人使用个人储蓄和信贷购买来平稳消费,从耐用品和服务中借款并重新分配资源用于食品消费。教育程度、配偶职业和年龄对消费也有积极影响。对应对策略的评估表明,这些策略不足以满足工人在冲击期间的需求。因此,该研究建议,政府应提供灵活的工作环境,制定一项允许工人多样化经营的政策,提供商业贷款,并鼓励为不确定性进行强制性储蓄。

Abstract Testing a model in property evaluation can be a difficult task due to the large variety of these models. The most popular models used in valuation are regression and neural networks. This paper applied a systematic review study and presents 11 types of regression models and 9 types of neural network models applied in real estate valuation. Our aim is to provide a tool for model selection applied in real estate valuation. The selection criteria were based on their applicability, user preferences and price estimation performance. The findings were slightly different from our expectations. Multi-Layer Perceptron (MLP) and Multiple Linear Regression (GLM) are the most applied and popular models in valuation.
摘要在性能评估中测试模型可能是一项困难的任务,因为这些模型种类繁多。估值中最常用的模型是回归和神经网络。本文应用系统回顾研究,提出了11种回归模型和9种神经网络模型在房地产估价中的应用。我们的目的是为房地产估价中的模型选择提供一个工具。选择标准基于它们的适用性、用户偏好和价格估算性能。研究结果与我们的预期略有不同。多层感知器(MLP)和多元线性回归(GLM)是估价中应用最广泛、最流行的模型。

Abstract Developing countries need higher economic growth to reach the level of developed countries. When developing countries exceed the potential economic growth, problems, such as, high external debt and high current deficit emerge. Such situations increase the financial risk of the country; in addition, international political risks, fluctuations in capital inflows and some manipulative movements have subjected countries to extreme exchange rate fluctuations. Purposes of this research: (1) to uncover the impact of high exchange rate volatility on small business activities and (2) to determine whether the level of exposure of the exchange rate shock on business owners varies by age. The methodology of the study involved a survey administered to 390 small and medium-sized enterprises (SMEs). The findings of the study show that after a period of significant exchange rate fluctuations, business activities were negatively affected, sales decreased, and job cuts increased. On the other hand, the exchange rate effect was mostly felt by all business owners of different ages. According to the study, it can be concluded that small enterprises are vulnerable to rising exchange rate volatility. The effect on SMEs with more work experience is not different. In order to alleviate the effects of adverse exchange rate movements, enterprises should be more cautious in their activities. Two suggestions can be made at this point: (i) Governments should follow optimal growth policies and (ii) Small businesses that have an important place in the economy should be made aware of the exchange rate risk and crisis management.
发展中国家需要更高的经济增长率才能达到发达国家的水平。当发展中国家的经济增长超出潜在水平时,就会出现高外债、高经常赤字等问题。这种情况增加了国家的财政风险;此外,国际政治风险、资本流入波动和一些操纵行为使各国汇率出现极端波动。本研究的目的:(1)揭示高汇率波动对小企业活动的影响;(2)确定汇率冲击对企业主的影响程度是否因年龄而异。这项研究的方法包括对390家中小型企业(SMEs)进行调查。研究结果表明,经过一段时间的汇率大幅波动后,商业活动受到负面影响,销售额下降,裁员增加。另一方面,不同年龄层的所有企业主都感受到了汇率效应。根据研究,可以得出结论,小企业容易受到汇率波动上升的影响。对工作经验较多的中小企业的影响也没有什么不同。为了减轻汇率不利变动的影响,企业在经营活动中应更加谨慎。在这一点上可以提出两点建议:(i)各国政府应遵循最佳增长政策;(ii)应使在经济中占有重要地位的小企业了解汇率风险和危机管理。

Abstract The aim of this paper is to present and analyze the labour market from the perspective of self-employment. It investigates the phenomenon of this form of employment from several aspects: on the one hand, it examines the factors influencing the choice of Israelis to be self-employed among Arabs and Jews in Israel, and, on the other hand, it examines the extent to which human capital and family background characteristics determine the employment choice. The main aim of the paper is to characterize the phenomenon of self-employment in the labour market. By using 2008 data Israel Census, hypotheses concerning the effect of demographical variables on self-employment are formulated and tested, using logistic regression. The results support the research hypotheses, and the most notable predictors of self-employment are discussed. Thus, we conclude that family background, gender, age, number of children and an interaction between nationality and occupation are the most significant predictors of self-employment. Many factors affect the self-employment status of citizens of Israel, with the single strongest predictor being gender – males in Israel are more likely to be self-employed. Also, more urbanized areas such as Tel-Aviv and the Centre, have higher self-employment rate than less populated areas such as the South.
摘要本文的目的是从自营职业的角度来介绍和分析劳动力市场。它从几个方面调查了这种就业形式的现象:一方面,它考察了在以色列的阿拉伯人和犹太人中影响以色列人选择自营职业的因素,另一方面,还考察了人力资本和家庭背景特征在多大程度上决定了就业选择。本文的主要目的是描述劳动力市场中的自营职业现象。利用2008年以色列人口普查数据,采用逻辑回归方法,建立并检验了人口统计学变量对自营职业影响的假设。研究结果支持了研究假设,并讨论了自营职业最显著的预测因素。因此,我们得出结论,家庭背景、性别、年龄、子女数量以及国籍和职业之间的相互作用是自营职业的最重要预测因素。许多因素影响以色列公民的自营职业状况,其中最有力的预测因素是性别——以色列的男性更有可能是自营职业者。此外,特拉维夫和市中心等城市化程度较高的地区的自营职业率高于南部等人口较少的地区。

Abstract According to Regional Innovation Scoreboard 2016, Romania’s regions, including the Bucharest-Ilfov region, are classified as modest innovators. This paper’s objective is to identify certain potential ways of economic growth of the Romanian regions through its innovation absorptive capacity and innovation development capacity, according to the AC/DC model of the National Endowment for Science, Technology and the Arts (NESTA), UK. Using the 2016 pillar scores of the Regional Competitiveness Index (RCI) - Innovation sub-index, we analyze their compatibility with the NESTA model and assess the potential of Romanian regions to absorb external innovation. The paper proposes a qualitative and quantitative approach based on empirical evidence. The poor performances of the Romanian regions regarding innovation, as they were analyzed in this paper, draw attention to Romania’s need to exploit innovation brought in from abroad. The main conclusion of our analysis is that Romania has failed to reach the absorption threshold of innovation that would allow it to accelerate the value-creating processes. The ability to innovate completes the ability to absorb. A detailed analysis of the causes of the reduced absorption capacity could also provide solutions for accelerating economic growth. We also formulate policy recommendations to increase Romania’s regional competitiveness through the development of innovation capacity.
摘要根据2016年地区创新记分牌,罗马尼亚的地区,包括布加勒斯特-伊尔福夫地区,被归类为适度的创新者。本文的目的是根据英国国家科学、技术和艺术基金会(NESTA)的AC/DC模型,通过罗马尼亚地区的创新吸收能力和创新发展能力,确定罗马尼亚地区经济增长的某些潜在途径,我们分析了它们与NESTA模型的兼容性,并评估了罗马尼亚地区吸收外部创新的潜力。本文提出了一种基于经验证据的定性和定量方法。本文分析了罗马尼亚各地区在创新方面的糟糕表现,这引起了人们对罗马尼亚利用国外创新的需求的关注。我们分析的主要结论是,罗马尼亚未能达到吸收创新的门槛,从而加快创造价值的进程。创新的能力就是吸收的能力。对吸收能力下降的原因进行详细分析,也可以为加快经济增长提供解决方案。我们还制定了政策建议,通过发展创新能力来提高罗马尼亚的区域竞争力。
