The appearance of coronavirus in the spring of 2020 has significantly revalued risk exposures in the business environment, which required new approaches in the measurement of financial risks. This paper defines and explains a new approach to the measurement of liquidity risk in companies in a time of an economic crisis. This approach is more responsive to stressful circumstances in the business environment and measures the time in an economic crisis when a company can still pay maturing liabilities out of its own inventory of liquid assets, where sales of a company on the market are limited or completely prohibited, as this was the case for some industries during the first wave of Covid -19 in spring 2020. The objective of this paper was to define a new metric for the measurement of corporate liquidity, which is sensitive to this environment and shows the propensity of a company to the risk of illiquidity if an economic crisis appears. This paper, in the next step, leverages the newly defined metric of corporate liquidity and calculates the average liquidity of all companies, as well as the average liquidity by business sectors in the Serbian economy, to discuss corporate liquidity in a crisis. The results show that the average liquidity of the Serbian economy in crisis at the end of 3Q 2020 was 78,02 days, i.e., the average company in the Serbian economy was able to survive 78,02 days in stress by the end of 3Q 2020 if its sales on the market were prohibited. © 2023,Central European Business Review.

冠状病毒在2020年春季的出现大大重估了商业环境中的风险敞口,这需要在衡量金融风险方面采取新的方法。本文定义并解释了一种在经济危机时期衡量公司流动性风险的新方法。这种方法更能应对商业环境中的紧张情况,并衡量在经济危机中,公司仍然可以从自己的流动资产库存中支付到期负债的时间,在这种情况下,公司在市场上的销售受到限制或完全禁止,就像2020年春季新冠肺炎-19第一波疫情期间的一些行业一样。本文的目的是定义一种新的衡量公司流动性的指标,该指标对这种环境很敏感,并显示了如果出现经济危机,公司流动性风险的倾向。下一步,本文将利用新定义的企业流动性指标,计算所有公司的平均流动性,以及塞尔维亚经济中各商业部门的平均流动率,以讨论危机中的企业流动率。结果显示,在2020年第三季度末,处于危机中的塞尔维亚经济的平均流动性为78,02天,即,如果禁止在市场上销售,塞尔维亚经济中的平均公司到2020年第3季度末能够在压力下生存78,02日。©2023,《中欧商业评论》。保留所有权利。

According to the duration of the health crisis caused by the COVID-19 virus, this study examines Serbian tourists' perception of risk (travel risk, destination risk, health and psychological risk, and financial risk) in two different periods of the crisis. The collection of primary data was performed using the questionnaire technique, and the research was conducted during May 2020 (363 respondents) and January 2021 (360 respondents). The research findings revealed that the perception of risk is higher in the first period of the health crisis compared to the second observed period, except for health and psychological risk (higher in the second period of the crisis). After observing both periods of health crisis and the examined control variables (gender, age, monthly income, level of education, travel intention, crisis period), the findings of linear hierarchical regressions indicate that the perception of travel risk and health and psychological risk is significantly influenced by education and travel intention, while the perception of destination risk and financial risk is influenced by travel intention. The results of the cluster analysis identified three characteristic clusters ("carefree", "relaxed", and "concerned") and a change in cluster composition during two periods of the COVID-19 crisis. The results of the study are discussed, the implications are stated, and the directions of further research are suggested. Implications for Central European audience: The study's findings contribute toward understanding the risk perception of travel in the period of health crisis caused by COVID-19 infection, which can help destination and marketing managers form strategies to reduce risk perception, which is crucial for the recovery of the national and global tourism industry. Also, organizers and tourist destinations since the recovery of tourism will depend on their ability to develop strategies to attract different segments of Serbian tourists in the crisis and postcrisis period.
根据新冠肺炎病毒引起的健康危机的持续时间,本研究考察了塞尔维亚游客在危机的两个不同时期对风险(旅行风险、目的地风险、健康和心理风险以及财务风险)的感知。使用问卷技术收集了主要数据,研究于2020年5月(363名受访者)和2021年1月(360名受访者)进行。研究结果显示,与第二个观察期相比,健康危机第一阶段的风险感知更高,但健康和心理风险除外(危机第二阶段更高)。在观察了健康危机时期和所检查的控制变量(性别、年龄、月收入、教育水平、旅行意向、危机期)后,线性分层回归的结果表明,对旅行风险和健康心理风险的感知受到教育和旅行意向的显著影响,而对目的地风险和财务风险的感知受到旅行意向的影响。集群分析的结果确定了三个特征集群(“无忧无虑”、“放松”和“关注”),以及新冠肺炎危机两个时期集群组成的变化。对研究结果进行了讨论,阐述了研究的意义,并提出了进一步研究的方向。对中欧观众的影响:该研究的发现有助于理解新冠肺炎感染引发的健康危机期间旅行的风险感知,这可以帮助目的地和营销经理制定降低风险感知的策略,这对国家和全球旅游业的复苏至关重要。此外,自旅游业复苏以来,组织者和旅游目的地将取决于他们制定战略的能力,以在危机和危机后时期吸引不同阶层的塞尔维亚游客。

The so-called agile approach is increasingly popular in the world of project management as a response to more dynamic and competitive environments. This study follows the question: What are the decisive criteria that result in the use of agile process models in practice? Therefore, a broad range of decision criteria is investigated, representing different reasons for firms to decide in favour or against the usage of agile process models, namely: Time-saving, increased efficiency, availability of qualified personnel, uniform terminology, project comparability and functions as a knowledge base. Most existing research on agile project management is of qualitative nature; this study uses a quantitative approach to assessing 51 firms and nine different industries within the DACH region. The collected data was analysed in a binary logistic regression model. Results reveal that time-saving positively predicts the use of agile process models, while high ratings in function as a knowledge base and project comparability predict the absence of agile process models. Therefore, practitioners are suggested to educate project and portfolio managers in the creation of hybrid environments and integration of agile process models in traditional project portfolios. Implications for Central European audience : The results of this study provide valuable insights into the selection of project management approaches across different industries in the DACH region. industry and x 8 = firm size, are added to the model, with industry designed as a categorical variable with the dimensions IT and “Other”. The analysis was carried out with the Statistical Package for Social Sciences (SPSS Version 27). The Wald statistics and the p-values are considered to assess whether the suggested causalities result in significant correlations in the model. For this study, a p-value of p < 0.05 is considered significant. The Hosmer-Lemeshow test is applied to determine the overall quality of the model (goodness-of-fit), providing information to what degree the estimated model fits the data sample, dividing the observations into groups and comparing the predicted observations with the actual observations for each group. Based on this comparison, the Chi-square test is then carried out. The result showed significance (p<0.05), indicating that there is a significant deviation between the model and the data. The odds ratio (Exp(ß)) is considered to assess the effect strength of the respective predictor variables. The odds ratio gives the change in the probability of the event Y=1, if one independent variable is increased by one unit, given that all the other variables of the model are held constant. For negative odds ratios, the reciprocal value is calculated.
所谓的敏捷方法在项目管理领域越来越流行,作为对更动态和竞争环境的响应。本研究遵循以下问题:在实践中使用敏捷过程模型的决定性标准是什么?因此,研究了广泛的决策标准,代表了公司决定支持或反对使用敏捷过程模型的不同原因,即:节省时间,提高效率,合格人员的可用性,统一的术语,项目可比性和作为知识库的功能。现有的敏捷项目管理研究大多是定性的;本研究采用定量方法对DACH地区的51家公司和9个不同行业进行了评估。收集的数据在二元逻辑回归模型中进行分析。结果表明,时间节约积极地预测了敏捷过程模型的使用,而作为知识库的功能和项目可比性的高评级则预测了敏捷过程模型的缺乏。因此,建议从业人员在创建混合环境和在传统项目组合中集成敏捷过程模型方面对项目和投资组合经理进行培训。对中欧受众的影响:本研究的结果为DACH地区不同行业的项目管理方法选择提供了有价值的见解。将行业和x8 =企业规模添加到模型中,将行业设计为具有IT和“其他”维度的分类变量。分析是用社会科学统计软件包(SPSS 27版)进行的。考虑Wald统计量和p值来评估所建议的因果关系是否导致模型中的显著相关性。在本研究中,p值< 0.05被认为是显著的。Hosmer-Lemeshow检验用于确定模型的整体质量(拟合优度),提供估计模型与数据样本拟合程度的信息,将观测值分成组,并将每组的预测观测值与实际观测值进行比较。基于这种比较,然后进行卡方检验。结果显示显著性(p<0.05),说明模型与数据存在显著偏差。比值比(Exp(ß))被用来评估各自预测变量的影响强度。如果一个自变量增加一个单位,假设模型的所有其他变量保持不变,那么比值比给出了事件Y=1的概率变化。对于负比值比,计算倒数值。

Readability of Annual Reports on the Vienna Stock Exchange: A Test of Management Obfuscation Hypothesis 维也纳证券交易所年度报告的可读性:管理混淆假说的检验

This research examines the relation between annual report readability and company performance in a German-speaking country, Austria. The incomplete revelation hypothesis, management obfuscation hypothesis and agency theory assume that firms with lower performance strategically use readability in their disclosures to obfuscate negative results. For investors, reading, analysing, and interpreting data becomes a costly affair; this weakens the negative effect of such data on a firm’s reputation and share price. We use LIX and Flesch formulas to measure the readability of letters to the shareholders and/or interviews with the board in annual reports. The sample consists of 37 companies that are listed on the Prime Market of the Vienna Stock Exchange and their data from the year 2009 to 2020. Company performance is measured by the change in turnover, profit, and share price. The analysed sections mostly show high to very high levels of difficulty. During the observation period, readability levels do not change significantly. We find that the annual reports of firms with lower performance are not harder to read and, therefore, cannot confirm the management obfuscation hypothesis. A significant influence of change in profit/loss on readability is minutely observed. Possible reasons for this observation could be characteristics of the German language, statistical outliers, the long observation period, more professional investor relations offices, and changing communication channels between companies and stakeholders. The last point, changing communication channels, also puts the obfuscation hypothesis and its application to readability up for discussion again. Implications for Central European audience : Our study shows that also Central European countries are confronted with low levels of readability in annual reports.

本研究考察了德语国家奥地利的年度报告可读性与公司业绩之间的关系。不完全披露假说、管理混淆假说和代理理论认为,业绩较低的公司在战略上利用披露的可读性来混淆负面结果。对投资者来说,阅读、分析和解释数据是一件代价高昂的事情;这削弱了此类数据对公司声誉和股价的负面影响。我们使用LIX和Flesch公式来衡量年度报告中致股东的信件和/或董事会访谈的可读性。样本包括在维也纳证券交易所黄金市场上市的37家公司及其2009年至2020年的数据。公司业绩是通过营业额、利润和股价的变化来衡量的。分析的部分大多显示出高到极高的难度。在观察期间,可读性水平没有显著变化。我们发现,业绩较低的公司的年度报告并不难阅读,因此,无法证实管理层混淆假说。利润/损失的变化对可读性的显著影响被仔细观察到。这种观察的可能原因可能是德语的特点、统计异常值、观察期长、投资者关系办公室更专业,以及公司和利益相关者之间不断变化的沟通渠道。最后一点,改变沟通渠道,也将模糊假设及其在可读性方面的应用再次提出来讨论。对中欧受众的影响:我们的研究表明,中欧国家也面临着年度报告可读性低的问题。尽管如此,我们看不到在公司披露中存在混淆的明显趋势。我们在

Sources of Value-Added in V4 automotive GVCs: The Case of Transport and Storage Services and Firm Level Technology Absorption V4汽车全球价值链的增值来源:以运输和仓储服务业与企业层面的技术吸收为例
IF 1.3 Q3 BUSINESS Pub Date : 2022-03-07 DOI: 10.18267/j.cebr.301

Within V4 automotive Global Value Chains (GVCs), technologies absorbed by the corporate sector represent a significant impact on the level of value-added created within the economy. Sectoral and geographic targeting of our research is determined by the export of motor vehicles, trailers, and semi-trailers produced in the V4 countries. The article’s main objective was to investigate the role of services provided by V4 countries within GVCs with an emphasis on transport and storage. The authors used the method of linear regression analysis to answer two central research questions. Is there a synergic or spillover effect within the automotive clusters of the V4 countries in creating value-added originating in the logistic services? What role absorption of technology at the firm level in EU27 countries (the most important trading partners of the V4 countries) plays in creating value-added in the V4 automotive sector? Authors found differentiated results within V4 countries, confirming the hypothesis related to technology absorption. Implications for Central European audience: Despite high V4 export performance, the research suggests how to increase the value-added through higher involvement within GVCs (particularly the automotive industry). The paper demonstrates a positive impact of importing transport services from the EU countries to some V4 countries (Slovakia, Czechia, and Poland) and its value-added content in gross exports. For any V4 country, an increase in the quality of the business environment of EU trade partners (measured as the corporate level of technology absorption) results in a lower value-added creation, quite significantly, with lower effect in the case of Czechia, but more than 15% decrease in case of Poland, Hungary, and Slovakia.
在V4汽车全球价值链(GVCs)中,企业部门吸收的技术对经济中创造的增值水平产生了重大影响。我们研究的部门和地理目标是由V4国家生产的机动车辆、挂车和半挂车的出口决定的。本文的主要目的是调查V4国家提供的服务在全球价值链中的作用,重点是运输和储存。作者运用线性回归分析的方法回答了两个中心研究问题。V4国家的汽车集群在创造源自物流服务的增值方面是否存在协同效应或溢出效应?欧盟27国(V4国家最重要的贸易伙伴)在企业层面吸收技术在V4汽车行业创造增值方面发挥了什么作用?作者在V4国家中发现了不同的结果,证实了与技术吸收有关的假设。对中欧受众的影响:尽管V4出口表现良好,但研究建议如何通过更高程度地参与全球价值链(特别是汽车行业)来增加附加值。本文论证了从欧盟国家进口运输服务对一些V4国家(斯洛伐克、捷克和波兰)的积极影响及其在出口总额中的增值含量。对于任何一个V4国家来说,欧盟贸易伙伴商业环境质量的提高(以企业技术吸收水平衡量)都会导致增加值创造的降低,这一点非常显著,对捷克的影响较小,但对波兰、匈牙利和斯洛伐克的影响超过15%。

This study aims to predict and assess the antecedents of use social commerce using dualstage structural equation modelling and artificial neural network analysis. This study sheds light on the role of perceived risks in developing the relationship of each of the social bonds and the social network on the convenience of adopting wearable payment. The interactive role of barriers of using the wearable payment for the relationship convenience of adopting wearable payment and intention to use social commerce was also explored. Finally, this study highlighted the effect of the mediating variable of the convenience of adopting wearable payment. The survey was adopted by surveying 334 people with an online shopping experience. The results confirmed the role of interactive variables, perceived risk, and barriers of using wearable payment in increasing intention to use social commerce. On the other hand, the convenience of wearable payment adoption has fully mediated the relationship between social bonds, social network theories and intention to use social commerce. Implications for Central European audience: The findings of this study contribute to providing academics and practitioners with a deep insight into the antecedents of social commerce to develop practices and policies that increase intentions to use social commerce.

Netnography, an online qualitative research method that evolved from ethnography, previously typically used in anthropology, is experiencing its boom in contemporary marketing research worldwide. It helps to answer research questions about a variety of topics, and it is used in many different ways. Therefore, each netnographic study is unique, not only content-wise but also in terms of the approach to the use of the method. In the presented paper, the case study research method was applied to aim at the identification of the best practices in contemporary marketing research when using netnography. Based on the analysis of chosen articles published in peer-reviewed academic journals, the paper defines the features of the research problem suitable for the application of netnography, the typical process, and its variances, as well as basic criteria for use. As a result of observed significant differences in applying the method, the paper captures the variability of netnography use in the Model of NET Dimensions of Netnography. The model shows how each netnographic study has to deal with three dimensions of decisions that need to be taken: ‘the Niche’ – the place ‘where’ and the group ‘whom’ it researches, ‘the Engagement’ – the extent to which the researcher is engaged in the studied community, and ‘the Time’ – the timeline – ‘when’ and timespan ‘how long’. The combination of all the possibilities of NET dimensions makes the netnography so variable, flexible, and adaptable, and therefore a very suitable method for many research problems.Implications for Central European Audience: The paper presents the variety of use of netnography in contemporary marketing research. Although the method originated at the end of the 20th century and is starting to be very popular worldwide, especially with the growth of life online, there is still very little research done using this method in the CEE. Researching the various scholar engines at the time of the article submission, we found very few published studies originating from the CEE. And yet, as the presented paper shows, the method is very well-fitting for a large variety of research problems, and it is very handy, especially now when other qualitative methods are often more difficult to be carried out due to COVID-19 restrictions. The method has the potential to help to answer many of the real businesses’ questions as well as to solve some academic puzzles. Therefore, we see a need to promote it within the academic and business community.
网络志是一种由人种志演变而来的在线定性研究方法,以前通常用于人类学,在当代全球市场研究中正在蓬勃发展。它有助于回答关于各种主题的研究问题,并以许多不同的方式使用。因此,每个网络研究都是独特的,不仅在内容方面,而且在使用方法的方法方面。在本文中,案例研究的研究方法被应用于旨在识别最佳实践在当代营销研究时,使用网络学。本文在对同行评议学术期刊上发表的文章进行分析的基础上,界定了适合网络志应用的研究问题的特征、典型过程、差异及其使用的基本标准。由于在应用该方法时观察到的显著差异,本文在网络学的网络维度模型中捕获了网络学使用的可变性。该模型显示了每个网络研究必须如何处理需要采取的决策的三个维度:“利基”——它研究的地点和群体,“参与”——研究者参与研究社区的程度,以及“时间”——时间轴——“何时”和时间跨度——“多长”。NET维度的所有可能性的组合使得网络学如此可变、灵活和适应性强,因此是一种非常适合于许多研究问题的方法。对中欧受众的影响:本文介绍了当代营销研究中网络学的各种使用。尽管该方法起源于20世纪末,并开始在全球范围内非常流行,特别是随着在线生活的增长,但在中东欧使用该方法进行的研究仍然很少。在文章提交时对各种学者引擎进行研究,我们发现很少有来自中东欧的已发表研究。然而,正如本文所示,这种方法非常适合于各种各样的研究问题,而且非常方便,特别是在其他定性方法由于COVID-19的限制而往往难以实施的情况下。这种方法有可能帮助回答许多真正的商业问题,以及解决一些学术难题。因此,我们认为有必要在学术界和商界推广它。

GLOCALISATION AND READINESS FOR OPEN INNOVATION: THE ROLE OF INSTITUTIONAL SUPPORT IN TRANSITIONAL ECONOMIES 全球化与开放创新的准备:制度支持在转型经济中的作用
IF 1.3 Q3 BUSINESS Pub Date : 2022-02-23 DOI: 10.18267/j.cebr.302

Studies on institutional support for the internationalisation of firms from transitional economies are inconclusive. This research contributes to the studies of institutional support in cases of firms with complementary innovation – internationalisation strategies. Mixed method research is used to support quantitative structural modelling. It uses qualitative interview data in combination with quantitative data gathered by a survey questionnaire on a sample of 88 telecommunications firms from the Croatia economy the year after it joined the European Union (2014). SmartPLS model is used to analyse data obtained through a questionnaire survey. The results show that institutions can assist firms in recombining their processes when they offer concrete product development support and, to a lesser extent, marketing support. The recombination of firms’ processes, i.e. its ability to openly innovate, leads to significantly better globalised-localised (glocal) financial and marketing performance, which results are robust. The results are inconclusive in the case of glocal growth performance. The structural model assessed the effect of readiness for open innovation on glocal growth as positive and insignificant, while the robustness check found it to be positive and significant. Implications for Central European audience: The value of this study is twofold. Firstly, it provides support and direction according to which institutional support could be directed to strengthen the internationalisation effort of the incumbent industry from transitional Central European economy that has transformed from the socialist to a market economy and undergone a process of joining the European Union. Secondly, it shows managers weak spots in institutional support and enables them to mitigate them quicker by finding similar support either outside of the firm on international markets or by employing highly qualified individuals.
对转型经济体企业国际化的制度支持的研究尚无定论。本研究有助于研究具有互补性创新-国际化战略的企业的制度支持问题。混合方法研究为定量结构建模提供支持。它将定性访谈数据与定量数据相结合,这些数据是通过对克罗地亚经济中88家电信公司的调查问卷收集的,该调查是在克罗地亚加入欧盟(2014年)后的一年进行的。SmartPLS模型用于分析通过问卷调查获得的数据。结果表明,当机构提供具体的产品开发支持,并在较小程度上提供营销支持时,机构可以帮助企业重组其流程。企业流程的重组,即其公开创新的能力,显著提高了全球化-本地化(glocal)的财务和营销绩效,其结果是稳健的。在全球增长绩效的情况下,结果是不确定的。结构模型评估开放式创新准备度对全球增长的影响为正且不显著,而鲁棒性检验发现它是正且显著的。对中欧受众的启示:本研究的价值是双重的。首先,它为从社会主义经济向市场经济转型并经历了加入欧盟进程的中欧转型期经济中现有产业的国际化努力提供了制度性支持和方向。其次,它显示了管理人员在机构支持方面的弱点,并使他们能够通过在公司外部的国际市场上寻找类似的支持或雇用高素质的个人来更快地缓解这些弱点。
