Abstract Despite a considerable body of research and gathering information on advanced technologies, there is still a study gap concerning its importance from the perspective of international competitiveness. Therefore, a question arises: what affects the competitive potential and how does it contribute to the competitive position of the high-tech sector in European Union (EU) countries? For this reason, a study was taken up to evaluate the competitive potential and competitive position of the high-tech sector in EU countries. Defining the competitiveness, competitive potential, and competitive position in the industry was the starting point for the analysis. Further, selected indices were used to evaluate the competitive potential and to establish a competitive position. The synthetic competitiveness index was also calculated. The study identified the decisive factors having an impact on the competitive potential and competitive position of the sector and the relationship between them.
尽管对先进技术进行了大量的研究和收集,但从国际竞争力的角度来看,先进技术的重要性仍然存在研究差距。因此,出现了一个问题:什么影响竞争潜力,它如何有助于欧盟(EU)国家高科技部门的竞争地位?为此,进行了一项研究,以评价欧盟各国高技术部门的竞争潜力和竞争地位。定义行业中的竞争力、竞争潜力和竞争地位是分析的起点。此外,选定的指标被用来评估竞争潜力和建立竞争地位。并计算了综合竞争力指数。该研究确定了影响该部门竞争潜力和竞争地位的决定性因素及其之间的关系。

Abstract The underpricing phenomenon on financial markets has long been the research subject in many financial areas – from neoclassical to behavioral finance. Once confirmed as a persistent pattern, it has begun an ongoing discussion as to its possible causes. Our study examined the phenomenon of IPO underpricing for companies from the game sector in Poland from 2016 to 2020. Many IPOs in Poland have attracted both international companies and investors, making the Warsaw Stock Exchange a kind of financial hub for game companies. Analyzing the whole IPO market in Poland, we however found substantial IPO underpricing, which is statistically higher in the game sector than in the no-game group of debuting companies. Our research argues that the issuer's industry may influence the size of the IPO's first-day return. We also noticed that the way the IPO was carried out influenced the underpricing. Greater underpricing characterized private offers compared to public offers.
从新古典经济学到行为金融学,金融市场的定价过低现象一直是许多金融领域的研究课题。一旦确认这是一种持续的模式,就开始了对其可能原因的持续讨论。我们的研究考察了2016年至2020年波兰游戏行业公司IPO定价过低的现象。波兰的许多ipo吸引了国际公司和投资者,使华沙证券交易所成为游戏公司的金融中心。然而,在分析波兰整个IPO市场时,我们发现了大量的IPO定价过低,从统计数据来看,游戏行业的IPO定价低于非游戏公司。我们的研究认为,发行人所在的行业可能会影响IPO首日收益的大小。我们还注意到,IPO的实施方式影响了定价过低。与公开招股相比,私人招股的定价更低。

Abstract The purpose of the article is to review and critique the implementation of food export restrictions in times of crisis in addressing food security challenges. The methodological approach was to undertake a narrative literature review to outline the challenge of ensuring food security in times of crisis. We explored the problem of food export restrictions introduced in 2007–2008 and 2020 and assessed the changes in the state of food security at the national level during the COVID-19 pandemic using the Global Food Security Index (GFSI). The trade restrictions imposed in 2020 did not play a key role in the increases in international food prices as was the case during 2007–2008 and 2010–2011. The analysis of GFSI values questions whether food export restrictions have been sufficient measures given the size of the food security challenge during the pandemic, and this is a new contribution of this research. The issue of food export restrictions is underregulated in the World Trade Organization (WTO), and this needs to be urgently addressed by another institution, e.g., Food and Agriculture Organization (FAO), given that the war in Ukraine is endangering food security across the world.
摘要本文的目的是回顾和批判危机时期食品出口限制的实施,以应对粮食安全挑战。方法学上的方法是进行叙述文献审查,概述在危机时期确保粮食安全的挑战。我们探讨了2007-2008年和2020年实施的粮食出口限制问题,并利用全球粮食安全指数(GFSI)评估了2019冠状病毒病大流行期间国家层面粮食安全状况的变化。与2007-2008年和2010-2011年的情况不同,2020年实施的贸易限制并未在国际粮食价格上涨中发挥关键作用。GFSI的分析值质疑,鉴于疫情期间粮食安全挑战的规模,粮食出口限制措施是否足够,这是本研究的一项新贡献。世界贸易组织(WTO)对粮食出口限制的监管不足,鉴于乌克兰的战争正在危及世界各地的粮食安全,这一问题需要另一个机构,例如粮食及农业组织(FAO)紧急解决。

Abstract This article sheds new light on the informational efficiency of the cryptocurrency market by analyzing investment strategies based on structural factors related to on-chain data. The study aims to verify whether investors in the cryptocurrency market can outperform passive investment strategies by applying active strategies based on selected fundamental factors. The research uses daily data from 2015 to 2022 for the two major cryptocurrencies: Bitcoin (BTC) and Ethereum (ETH). The study applies statistical tests for differences. The findings indicate informational inefficiency of the BTC and ETH markets. They seem consistent over time and are confirmed during the COVID-19 pandemic. The research shows that the net unrealized profit/loss and percent of addresses in profit indicators are useful in designing active investment strategies in the cryptocurrency market. The factor-based strategies perform consistently better in terms of mean/median returns and Sharpe ratio than the passive “buy-and-hold” strategy. Moreover, the rate of success is close to 100%.
本文通过分析基于链上数据相关结构性因素的投资策略,对加密货币市场的信息效率进行了新的阐释。该研究旨在验证加密货币市场的投资者是否可以通过基于选定的基本因素应用主动策略来优于被动投资策略。该研究使用了2015年至2022年两种主要加密货币:比特币(BTC)和以太坊(ETH)的日常数据。该研究对差异进行了统计检验。研究结果表明BTC和ETH市场的信息效率低下。随着时间的推移,它们似乎是一致的,并在COVID-19大流行期间得到了证实。研究表明,利润指标中的净未实现利润/亏损和地址百分比对于设计加密货币市场的主动投资策略非常有用。基于因素的策略在平均/中位数回报和夏普比率方面的表现始终优于被动的“买入并持有”策略。此外,成功率接近100%。

Abstract Newly formed territorial communities acquire a real subjectivity in the processes of the management of territorial development: they become responsible for a significant share of day-to-day economic activities within their sphere of responsibility, especially in territories with a predominantly rural population. This article aimed to study the changing role of local self-government in ensuring the economic development of the low-urbanized territory, determining public opinion and expectations of residents from local governments in the new conditions. A public opinion poll of residents living in selected local communities was conducted. This article identified the objective factors of the level and pace of newly formed territorial communities’ development in Ukraine. It has been proved that the decentralization of power changes the role of local government and the expectations of residents from it and their assessments of the situation at the local level.
新成立的领土社区在管理领土发展的过程中获得了真正的主体性:它们对其责任范围内的大部分日常经济活动负责,特别是在以农村人口为主的领土。本文旨在研究在新形势下,地方自治在保障低城市化地区经济发展中的作用变化,以及地方政府对居民舆论和期望的影响。对居住在选定的当地社区的居民进行了民意调查。本文确定了影响乌克兰新成立的领土社区发展水平和速度的客观因素。事实证明,权力下放改变了地方政府的作用,改变了居民对地方政府的期望,改变了他们对地方局势的评价。

Abstract Mentoring programs developed at universities are an effective method of supporting student development. The participation in these programs brings them many benefits. These benefits include increased prestige in the community, gaining new experiences and achieving defined goals in the case of universities. It is essential to improve the mentoring programs implemented at universities. This article presents the results of research carried out within the framework of the BEGIN project implemented and funded under the Erasmusplus program. The aim of the research was to identify academic staff's experiences of participating in formal and informal mentoring programs. Ten in-depth interviews were conducted with respondents from Italy, Poland and Germany. A purposive selection method was used. The research provided clues with a practical dimension on how to implement mentoring programs, usefulness from the student's point of view, effectiveness and efficiency, and how to measure the impact of the program on students.

Abstract The paper aims to assess the International Financial Reporting Standard (IFRS) 16 “Leases” impact on the lessees’ financial situation. The study was conducted on the financial data for 2018–2019 of 494 companies listed on the Warsaw Stock Exchange using the difference-in-differences (DID) method. The hand-collected data on lease usage retrieved from the financial statements and the data for financial ratios obtained from the Orbis database were used. The research sample includes 308 preparers under IFRS and 186 entities applying accounting policies under the Polish Accounting Act. It is shown that the IFRS 16 implementation resulted in a significant increase in the debt-to-equity and debt-to-total assets ratios of lessees and a decrease in the profitability. We identified significant leverage increase in the trade and services sectors. The results confirm the conclusions of previous studies based on estimates, whose authors expected a significant differential effect of IFRS 16 implementation between industries.
摘要本文旨在评估国际财务报告准则(IFRS)第16号《租赁》对承租人财务状况的影响。该研究采用差分法对华沙证券交易所494家上市公司2018-2019年的财务数据进行了分析。使用了从财务报表中检索到的手工收集的租赁使用数据和从Orbis数据库获得的财务比率数据。本研究样本包括308家按照国际财务报告准则编制的企业和186家按照波兰会计法实施会计政策的企业。结果表明,实施国际财务报告准则第16号导致承租人的债务权益比率和债务与总资产比率显著增加,盈利能力下降。贸易和服务业杠杆率明显上升。该结果证实了先前基于估计的研究结论,这些研究的作者预计IFRS 16在不同行业的实施会产生显著的差异效应。

Abstract The study aims to empirically analyze the reaction of stock prices to the information about the conclusion and acceptance of a debtor–creditor arrangement under restructuring proceedings of companies listed on the stock exchange in Poland. The following main research hypothesis was verified: public disclosure of information about an arrangement conclusion and acceptance in restructuring proceedings results in above-average rates of return due to investments in the stocks of these entities in the short term. Three events were assessed: the public disclosure of information about the conclusion of a debtor–creditor arrangement (Event 1), its approval by a court (Event 2), and the decision becoming final (Event 3). The research method applied was the event study. Event 1 and Event 3 leads to an above-average and statistically significant increase in stock prices on the day of the event. In contrast, no statistically significant above-average rates of return accompanied Event 2.
摘要本研究旨在实证分析波兰证券交易所上市公司在重组程序中订立及接受债务-债权人安排的信息对股票价格的反应。以下主要研究假设得到验证:在重组程序中公开披露有关安排的结论和接受的信息,导致这些实体的股票投资在短期内的回报率高于平均水平。本研究评估了三个事件:债务-债权人协议达成的信息公开披露(事件1)、获得法院批准(事件2)以及该决定成为最终结果(事件3)。研究方法为事件研究。事件1和事件3导致事件当天股票价格高于平均水平且具有统计学意义的上涨。相比之下,事件2没有统计学上显著的高于平均水平的回报率。

The coronavirus and center-peripheral relations in the economies of the European Union 冠状病毒与欧盟经济体的中心-边缘关系
IF 0.8 Pub Date : 2022-09-01 DOI: 10.2478/ijme-2022-0017

Abstract From the perspective of the diversity of capitalism and that of economic sociology, the article deals with the issue of center-peripheral relations as one of the key dimensions of economic diversification that determines the development opportunities of the European Union. The collapse of the convergence processes during the 2008–2010 financial crisis revealed the separateness of development trajectories of various countries and geographical regions of the EU. Without reversing this phenomenon and working out new mechanisms of development convergence and institutions supporting them, the process of European integration will enter further structural crises that may lead to the disintegration of the EU. Various classifications of the core and of the peripheries of the euro area are characterized, within which several types of countries are identified with different economic characteristics (countries of the Northern core and of the Southern peripheries of the euro area, different types of peripheries in Southern Europe and in Central and Eastern Europe, the internal core and the external core or the outer core, and the internal peripheries and the external peripheries, as well as the super-peripheries including candidates or potential candidates to join the EU). The COVID-19 crisis has an asymmetric impact on the economic situation of the Member States. As with other crises, this impact will be the result of the interconnection of the prior state of economies, structural differences in growth patterns, and responses to new challenges brought about by the pandemic. Also, the consequences of the pandemic for the reconfiguration of center-peripheral relations in the EU are discussed, with a particular focus on the CEE.
摘要:本文从资本主义多样性和经济社会学的视角出发,探讨了作为决定欧盟发展机遇的经济多元化的关键维度之一的中心-边缘关系问题。2008-2010年金融危机期间趋同进程的崩溃,揭示了欧盟不同国家和地理区域发展轨迹的分离性。如果不扭转这一现象,不制定新的发展趋同机制和支持机制,欧洲一体化进程将陷入进一步的结构性危机,可能导致欧盟解体。欧元区核心和外围的各种分类都有特点,其中几种类型的国家被确定为具有不同的经济特征(欧元区北部核心和南部外围的国家,南欧和中欧和东欧的不同类型的外围,内部核心和外部核心或外核心,以及内部外围和外部外围,以及超级外围国家,包括加入欧盟的候选人或潜在候选人)。2019冠状病毒病危机对会员国的经济形势产生了不对称影响。与其他危机一样,这种影响将是经济先前状况、增长模式的结构性差异以及对大流行病带来的新挑战的应对相互联系的结果。此外,还讨论了大流行对欧盟中心-边缘关系重新配置的影响,特别侧重于中东欧。

Abstract The study aims at estimating the effects of support for research and development and innovation from the European Union (EU) budget for boosting innovation in European enterprises, using input, output, and behavioral additionality approach. The study is based on microdata of the Community Innovation Survey 2012–2014, covering a sample of 98,809 enterprises from 14 EU countries. The direct and indirect relationships between the variables were studied using path analysis. For the whole sample, three additionality dimensions were confirmed; however, the result differs across EU member states. Multi-additionality of EU grants was confirmed only for Spain; in eight EU countries, input and behavioral additionality were proved, and in two, only behavioral additionality was found. This leads to the conclusion that the potential of EU support is not fully exploited, in particular in Central and Eastern European countries, and there is room for improvements with regard to policy design and implementation.
摘要本研究旨在运用投入产出和行为附加性方法,评估欧盟预算对研发和创新的支持对促进欧洲企业创新的影响。本研究基于2012-2014年社区创新调查的微观数据,涵盖了来自14个欧盟国家的98,809家企业样本。利用通径分析研究了各变量之间的直接和间接关系。对于整个样本,确定了三个附加性维度;然而,结果在欧盟成员国之间有所不同。欧盟的多项额外拨款只针对西班牙;八个欧盟国家证明了投入和行为附加性,两个国家只发现了行为附加性。由此得出的结论是,欧盟支持的潜力没有得到充分利用,特别是在中欧和东欧国家,在政策设计和执行方面还有改进的余地。
