Purpose: The aim of this paper is to analyze overall technical efficiency (OTE), pure technical efficiency (PTE) and scale efficiency (SE) of both life and non-life insurance sectors in three Central and Eastern European countries (CEE), i.e. Croatia, Hungary and Poland, in 2018. Methodology: The efficiency of insurance sectors is estimated by applying data envelopment analysis (DEA), while a one-way analysis of variance (ANOVA) is performed to find out whether there exists any statistically significant difference between the estimated levels of the efficiency of non-life and life insurance sectors in the observed CEE countries. Results: Out of 34 non-life Polish insurers, only two (6%) were overall technically efficient, while the remaining 32 were inefficient. Croatia and Hungary achieved better results with three (20%) and seven (43.7%) efficient insurers, respectively. However, when observing the life insurance segment, half of the Croatian life insurers were efficient according to the CCR model, while six (23%) Polish and three (23%) Hungarian efficient insurers were recorded. Conclusion: Research reveals that the Hungarian non-life insurers are the most efficient ones in terms of OTE, PTE and SE. They are followed by the Croatian insurers, leaving the Polish insurers behind. Regarding the life insurance sector, the domination of the Croatian insurers is recorded, while the Hungarian ones were found to be the least efficient. Moreover, inefficiency in both life and non-life sectors (except for the Hungarian life sector) is more related to scale than to managerial inefficiency. Finally, ANOVAs and Tukey post hoc tests revealed a statistically significant difference among considered groups of insurers.
目的:本文的目的是分析2018年中东欧三个国家(克罗地亚、匈牙利和波兰)寿险和非寿险行业的总技术效率(OTE)、纯技术效率(PTE)和规模效率(SE)。方法:通过应用数据包络分析(DEA)来估计保险部门的效率,同时进行单向方差分析(ANOVA)来确定在所观察的中东欧国家中,非寿险和寿险部门的效率估计水平之间是否存在统计学上的显著差异。结果:在34家波兰非寿险保险公司中,只有两家(6%)整体技术上有效,而其余32家效率低下。克罗地亚和匈牙利取得了更好的结果,分别有3家(20%)和7家(43.7%)高效保险公司。然而,在观察人寿保险细分市场时,根据CCR模型,克罗地亚有一半的人寿保险公司是高效的,而波兰有六家(23%),匈牙利有三家(23%)。结论:研究表明匈牙利非寿险保险公司在OTE、PTE和SE方面效率最高。克罗地亚保险公司紧随其后,将波兰保险公司抛在后面。关于人寿保险部门,克罗地亚保险公司占主导地位,而匈牙利保险公司的效率最低。此外,生命和非生命部门(匈牙利生命部门除外)的低效率更多地与规模有关,而不是与管理低效率有关。最后,anova和Tukey事后检验揭示了保险公司考虑组之间的统计学显著差异。

Purpose: Children in the Republic of Croatia are, as everywhere else in the world, active users of information and communication i.e. digital technologies, which is reflected in their daily habits and routines in the digital environment. The purpose of this paper is to find out if there are gender-based differences in behavior and established habits in the digital environment between boys and girls. Methodology: Quantitative research was carried out using the CAWI method among 400 parents or guardians in the Republic of Croatia who provided answers on (their own) children of primary school age. This paper focuses on the segment of children and their gender, i.e. the existence (or the lack of existence) of differences in the behavior of boys and girls in a digital environment. The statistically significant differences are demonstrated by testing various variables between the two above-mentioned segments. Results: The research results indicate that, on average, girls and boys start to use the Internet at the same age, approximately at the age of 6. However, there are noticeable differences between the sexes in terms of the habits and in the way they use the Internet. Conclusion: The conclusion shows that boys more frequently have desktop computers, laptops, and gaming consoles, and prefer to play online games and spend time in the online world, while girls more often post and publicly share photos, video records, and music. They equally use the Internet on weekdays, but boys spend more time on Internet activities on weekends.
目的:克罗地亚共和国的儿童同世界其他地方的儿童一样,是信息和通信即数字技术的积极使用者,这反映在他们在数字环境中的日常习惯和日常活动中。本文的目的是找出男孩和女孩在数字环境中的行为和既定习惯是否存在性别差异。方法:采用CAWI方法对克罗地亚共和国400名父母或监护人进行了定量研究,这些父母或监护人提供了(他们自己的)小学年龄儿童的答案。本文关注的是儿童及其性别,即数字环境中男孩和女孩行为差异的存在(或不存在)。通过对上述两个细分市场的各种变量进行检验,得出了具有统计学意义的差异。结果:研究结果表明,平均而言,女孩和男孩开始使用互联网的年龄相同,大约在6岁。然而,在使用互联网的习惯和方式方面,两性之间存在着明显的差异。结论:结论显示,男孩更频繁地使用台式电脑、笔记本电脑和游戏机,更喜欢玩网络游戏,花时间在网络世界中,而女孩更经常发布和公开分享照片、视频记录和音乐。他们在工作日使用互联网的时间是一样的,但男孩在周末花更多的时间在网络活动上。

Purpose: One of the ways to enhance transparency and usefulness of audit reports is to include information on key audit matters (KAMs). In this paper, based on the presented KAMs, we investigate transparency of audit reports of listed companies in Bosnia and Herzegovina and in Croatia. Methodology: For the purposes of this research, we collected and systematised data from published audit reports and then analysed them by means of descriptive statistical methods. Results: The research results show that in Croatia only a few audit reports lack a section on KAMs and there is no difference between the audit reports issued by the Big Four and the reports of other audit firms. In Bosnia and Herzegovina, most audit reports do not include a section on KAMs, but, unlike the Big Four, who disclose at least one KAM, other audit firms generally do not present any. Additionally, the research results show differences in the number of communicated KAMs between the audit reports prepared by the Big Four in Croatia and their reports for Bosnia and Herzegovina. There are also differences in the type of KAMs used in the two observed countries. Conclusion: Having analysed the situation in the two developing countries, we obtained different results. The discrepancies mainly stem from the varying degrees of transparency of the audit profession in each country.
目的:提高审计报告透明度和有用性的方法之一是纳入关键审计事项的信息。本文基于所提出的KAMs,对波黑和克罗地亚上市公司审计报告的透明度进行了研究。方法:为了本研究的目的,我们从公开的审计报告中收集和系统化数据,然后通过描述性统计方法对其进行分析。结果:研究结果表明,在克罗地亚,只有少数审计报告缺少KAMs部分,四大会计师事务所发布的审计报告与其他审计事务所的报告没有区别。在波斯尼亚和黑塞哥维那,大多数审计报告不包括KAM部分,但是,与四大会计师事务所披露至少一项KAM不同,其他审计事务所通常不提供任何KAM。此外,研究结果显示,四大会计师事务所在克罗地亚编写的审计报告与它们为波斯尼亚-黑塞哥维那编写的报告之间所传达的kam数量存在差异。两个被观察国家使用的kam类型也存在差异。结论:在分析了两个发展中国家的情况后,我们得到了不同的结果。这种差异主要源于各国审计行业透明度的不同程度。

Purpose: The purpose of this paper is to explore the potentials that can positively impact the success of a hotel online business by: (1) exploring the specifics of the internal structure of online booking channels in the hotel business, (2) identifying the value and distribution of the potential to increase hotel bookings through the hotel website, (3) identifying the potential by exploring the space for improving hotel website excellence, and (4) developing an innovative multidimensional metric for monitoring hotel website quality. Methodology: This research was approached in a way that the issue is considered from two aspects. Firstly, the potential to improve the ratio value of the hotel online booking channel structure is observed. The survey in the Republic of Croatia was conducted by regions on a sample of 4* and 5* hotels. Secondly, the potential to improve a hotel business is considered as the possibility to improve the performance of a hotel website. Results: The research results show the value and distribution of the potential which can be used for a positive impact on the hotel business. Furthermore, the use of the presented multidimensional metric model allows a clear recognition of the potential for the hotel website quality improvement. Conclusion: It can be concluded that both aspects of the potential research (in addition to the research findings), open up numerous possibilities for conducting similar or more complex analytical procedures and a new empirical research.
目的:本文的目的是探索通过以下方式对酒店在线业务的成功产生积极影响的潜力:(1)探索酒店业务中在线预订渠道内部结构的细节;(2)确定通过酒店网站增加酒店预订量的潜力的价值和分布;(3)通过探索提高酒店网站卓越性的空间来识别潜力;(4)开发一种创新的多维度指标来监测酒店网站质量。方法论:本研究是从两个方面来考虑问题的。首先,观察了酒店在线预订渠道结构的比例价值提升潜力。克罗地亚共和国的调查是按地区对4*和5*酒店进行的。其次,改善酒店业务的潜力被认为是改善酒店网站性能的可能性。结果:研究结果显示了潜力的价值和分布,可以对酒店业务产生积极的影响。此外,使用所提出的多维度量模型,可以清楚地认识到酒店网站质量改进的潜力。结论:可以得出结论,这两个方面的潜在研究(除了研究结果),开辟了许多可能性进行类似或更复杂的分析程序和新的实证研究。

Purpose: The purpose of this paper is to identify and evaluate the environmental impacts and estimate the external costs and benefits of building and operating a combined heat and power (CHP) plant. This research will contribute to the scientific literature in the field of public capital investments in CHP plants and facilitate the evaluation of similar assessments and studies by identifying relevant factors that affect society and the environment. Methodology: The ExternE methodology and Impact Pathway Approach (IPA) were used to estimate the externalities of building and operating the plant. The ExternE methodology considers environmental impacts, global warming impacts and accidents, and it is widely accepted in the estimation of externalities of CHP plants. Results: The main external benefits refer to the savings from the reduction of CO2 emissions per unit of energy produced, savings from the reduction of energy losses in the transmission of electricity, reduction of Croatia’s dependence on electricity imports, improvement of the balance of payments, and fiscal benefits. The main external costs arise from Croatia’s increasing import dependence on natural gas and changes in the use of agricultural land. Conclusion: It is estimated that the external benefits are higher than the external costs. In addition to the estimation of external costs, their internalization is done through various taxes and fees, thus affecting the unit cost of electricity. Further research should extend the estimation of external benefits and costs to consider broader social impacts and conduct a full cost-benefit analysis.
目的:本文的目的是确定和评估环境影响,并估计建造和运营热电联产(CHP)电厂的外部成本和效益。这项研究将有助于公共资本投资于热电联产电厂领域的科学文献,并通过确定影响社会和环境的相关因素,促进对类似评估和研究的评价。方法:使用外部方法和影响路径方法(IPA)来估计工厂建设和运营的外部性。externne方法考虑了环境影响、全球变暖影响和事故,在热电联产电厂的外部性估计中被广泛接受。结果:主要的外部效益包括单位能源生产二氧化碳排放量的减少、电力传输中能源损耗的减少、克罗地亚对进口电力依赖的减少、国际收支状况的改善和财政效益。主要的外部成本来自克罗地亚对天然气进口的日益依赖和农业用地使用的变化。结论:估计其外部收益高于外部成本。除了估算外部成本外,还通过各种税费将其内部化,从而影响电力的单位成本。进一步的研究应扩大对外部效益和成本的估计,以考虑更广泛的社会影响,并进行全面的成本效益分析。

Predictive accuracy of option pricing models considering high-frequency data 考虑高频数据的期权定价模型的预测准确性

Purpose: Recently, considerable attention has been given to forecasting, not only the mean and the variance, but also the entire probability density function (pdf) of the underlying asset. These forecasts can be obtained as implied moments of future distribution originating from European call and put options. However, the predictive accuracy of option pricing models is not so well established. With this in mind, this research aims to identify the model that predicts the entire pdf most accurately when compared to the ex-post “true” density given by high-frequency data at expiration date. Methodology: The methodological part includes two steps. In the first step, several probability density functions are estimated using different option pricing models, considering the values of major market indices with different maturities. These implied probability density functions are risk neutral. In the second step, the implied pdfs are compared against the “true” density obtained from the high-frequency data to examine which one gives the best fit out-of-sample. Results: The results support the idea that a “true” density function, although unknown, can be estimated by employing the kernel estimator within high-frequency data and adjusted for risk preferences. Conclusion: The main conclusion is that the Shimko model outperforms the Mixture Log-Normal model as well as the Edgeworth expansion model in terms of out-of-sample forecasting accuracy. This study contributes to the existing body of research by: i) establishing the benchmark of the “true” density function using high-frequency data, ii) determining the predictive accuracy of the option pricing models and iii) providing applicative results both for market participants and public authorities.
目的:最近,人们对预测给予了相当大的关注,不仅是对均值和方差的预测,还有对标的资产的整个概率密度函数(pdf)的预测。这些预测可以作为源自欧洲看涨期权和看跌期权的未来分布的隐含时刻来获得。然而,期权定价模型的预测准确性尚未得到很好的验证。考虑到这一点,本研究旨在确定与过期日期高频数据给出的事后“真实”密度相比,最准确地预测整个pdf的模型。方法论:方法论部分包括两个步骤。在第一步中,考虑不同期限的主要市场指数的值,使用不同的期权定价模型估计几个概率密度函数。这些隐含的概率密度函数是风险中性的。在第二步中,将隐含的pdf与从高频数据中获得的“真实”密度进行比较,以检查哪一个给出了最佳的拟合样本外。结果:研究结果支持这样一种观点,即“真正的”密度函数虽然未知,但可以通过在高频数据中使用核估计器并根据风险偏好进行调整来估计。结论:主要结论是Shimko模型在样本外预测精度方面优于MixtureLog-Normal模型以及Edgeworth展开模型。本研究对现有研究的贡献在于:i)利用高频数据建立“真”密度函数的基准,ii)确定期权定价模型的预测准确性,以及iii)为市场参与者和政府当局提供应用结果。

Purpose: The aim of this study is, first to describe and explore equity agency costs; second, to explore the impact of capital structure on equity agency costs; and finally, to examine the impact of agency costs on the performance of listed companies. Methodology: Panel data regression has been used for research data analysis. Results: The results of the work show that equity to capital and long-term debt to capital variables have a positive and significant impact on the agency costs of listed companies in the Republic of Croatia. The study indicates that long-term debt to capital variable has a negative and significant impact on the agency costs of listed companies in Slovenia and the Czech Republic. Furthermore, we find evidence to suggest that changes in agency costs have little or no effect on the performance of listed companies in Croatia, Slovenia and the Czech Republic. The findings suggest that the capital structure decisions affect the agency costs of listed companies and the agency costs may affect corporate performance. Conclusion: This study makes a number of contributions to the agency costs literature.

Results: The results of the work show that equity to capital and long-term debt to capital variables have a positive and significant impact on the agency costs of listed companies in the Republic of Croatia. The study indicates that long-term debt to capital variable has a negative and significant impact on the agency costs of listed companies in Slovenia and the Czech Republic.

Purpose: This paper aims to develop and validate the scale for measuring digital marketing orientation (DMO) in the hotel industry. Methodology: The robust exploratory and confirmatory factor analysis procedure is applied to a data set collected through an online survey of 164 hotels in Bosnia and Herzegovina, Croatia, Serbia, and Montenegro. Results: Digital marketing orientation has been conceptualized, and a scale has been developed to measure this construct. The scale consists of 15 items in three defined dimensions (subscales): Strategic emphasis, Digital intelligence generation, and Planning and resource provisioning. Conclusion: Using the developed digital marketing orientation (DMO) scale, hotel managers can conduct a DMO audit similar to conducting a market orientation audit to determine in which areas it is necessary to improve market orientation in the online environment. Academics may use the DMO scale to investigate its antecedents and the influence of other factors on DMO and/or the influence of DMO on other factors. This is the first study, to the author’s knowledge, that developed and validated a measurement scale for digital marketing orientation in the hotel industry.
目的:开发并验证酒店行业数字营销导向(DMO)的测量量表。方法:对波斯尼亚和黑塞哥维那、克罗地亚、塞尔维亚和黑山的164家酒店的在线调查收集的数据集应用了强大的探索性和验证性因素分析程序。结果:数字化营销取向已被概念化,并开发了一个量表来衡量这一结构。该量表由三个定义维度(子量表)中的15个项目组成:战略重点、数字智能生成、规划和资源供应。结论:利用开发的数字营销导向(DMO)量表,酒店管理者可以进行类似于市场导向审计的DMO审计,以确定在网络环境中哪些领域需要改进市场导向。学者们可以使用DMO量表来调查其前因以及其他因素对DMO的影响和/或DMO对其他因素的影响。据作者所知,这是第一次研究开发并验证了酒店行业数字营销导向的测量量表。

Real effective exchange rate and unemployment across post-transition Europe 转型后欧洲的实际有效汇率和失业率
IF 0.4 Pub Date : 2021-01-01 DOI: 10.51680/ev.34.2.1

Purpose: The aim of this paper is to examine the co-movement between the real effective exchange rate and unemployment across post-transition Europe. Methodology: The research data sample in this paper consists of monthly data from 2000M1 to 2019M6 for ten European post-transition countries. After standard correlation analysis, the research followed a wavelet coherence approach, provided time-series analysis in the time-frequency domain and illustrated evolution of the co-movements in the observed period. Results: Conventional approach research results suggest no significant correlation between variables under consideration in cases of Poland and Lithuania. In cases of Latvia and Slovenia, standard correlation coefficients were positive and not in line with the theory. Correlation coefficients supported the theoretical assumption in six other countries included in the study. Wavelet coherence analysis results provided deeper insights into the relationship over time and the frequency domain. Empirical results gained in this research revealed a decline in the unemployment rate accompanied by depreciation of the real effective exchange rate as a prominent pattern at the beginning of the observation period suggesting pro-cyclical monetary policy. Conclusion: During the crisis of 2008 no link between variables under consideration was confirmed, while after the crisis empirical results were in line with the theoretical assumption, suggesting that depreciation of the real effective exchange rate might be used as an instrument to boost employment.
目的:本文的目的是考察整个转型后的欧洲实际有效汇率和失业率之间的共同运动。方法:本文的研究数据样本包括10个欧洲转型后国家2000年1月至2019年6月的月度数据。在标准相关分析的基础上,采用小波相干方法,在时频域进行时间序列分析,说明了观测周期内共运动的演变。结果:传统方法的研究结果表明,在波兰和立陶宛的情况下,所考虑的变量之间没有显著的相关性。在拉脱维亚和斯洛文尼亚的情况下,标准相关系数是正的,不符合理论。相关系数支持该研究中其他六个国家的理论假设。小波相干分析结果提供了更深入的了解随时间和频域的关系。本研究的实证结果显示,在观察期开始时,失业率的下降伴随着实际有效汇率的贬值是一个突出的模式,这表明货币政策是顺周期的。结论:在2008年危机期间,所考虑的变量之间没有联系,而危机后的实证结果与理论假设一致,表明实际有效汇率的贬值可以作为促进就业的工具。

Purpose: The main objective of this research was to determine the impact of capital structure on the profitability of Croatian companies. The second objective was to analyze the consistency of the way in which capital structure is managed with respect to the existing theories of capital structure. Methodology: A survey was conducted on the sample of Croatian companies for the period from 2009 to 2019 using panel model GMM estimation. In order to be included in the sample, all shares listed on the Zagreb Stock Exchange were considered which meet the liquidity criterion and are part of the non-financial sector. Accordingly, the sample consists of 30 shares. Results: The research established a significant relationship between capital structure and profitability, with a negative sign. With these results, Croatian companies are placed alongside other companies from countries that belong to the group of developing countries, and diametrically opposed to the results obtained for the markets of developed countries. Indirectly, the validity of theories of capital structure formation on the Croatian market was tested, and it was proved that the behavior of Croatian companies can best be described by settings of the trade-off theory of capital structure. Conclusion: For Croatian companies, this means that any further use of debt will lead to a decline in profitability. Consequently, this means that domestic companies cannot make significant use of the current situation of low interest rates on loans, and therefore they lag behind in terms of the level of investments made.
目的:本研究的主要目的是确定资本结构对克罗地亚公司盈利能力的影响。第二个目标是分析资本结构管理方式与现有资本结构理论的一致性。方法:采用面板模型GMM估计对2009年至2019年期间克罗地亚公司样本进行调查。为了纳入样本,所有在萨格勒布证券交易所上市的股票都被认为符合流动性标准,并且是非金融部门的一部分。因此,样本由30股组成。结果:资本结构与盈利能力之间存在显著的负相关关系。由于这些结果,克罗地亚公司与属于发展中国家集团的国家的其他公司并列,与发达国家市场取得的结果截然相反。间接检验了克罗地亚市场资本结构形成理论的有效性,证明了克罗地亚公司的行为可以用资本结构权衡理论的设定来描述。结论:对克罗地亚公司来说,这意味着进一步使用债务将导致盈利能力下降。因此,这意味着国内企业不能充分利用目前低利率的贷款情况,因此在投资水平方面落后。
