The current study investigates how institutional constraints and firms’ and entrepreneurs’ characteristics affect business recovery. Some elements have not yet been rigorously examined in the existing literature, especially not concerning the post-communist countries’ business recovery component and the same is the research gap current study intended to address. To evaluate the study model, ordinal logistic regression was used. More than 300 valid questionnaires are collected from the Czech Republic, Hungary, and Serbia. The findings show that factors such as firm tenure and size, location, sector, entrepreneurial motivation, product change, etc., have conflicting effects on business recovery. Some of the outcomes of the present study is supported by the existing studies and some requires further research. The study focuses on the less explored independent variables and their association with business recovery, specifically on SMEs, which highlights the paper’s originality. The output of the current study adds to the existing literature of business recovery and institutional constraints. Policymakers interested in removing institutional limitations and promoting a quicker business recovery for SMEs are drawn to the research. The study findings are also helpful from a managerial standpoint because business owners and managers significantly impact decisions about entrepreneur motivation, product change, and other issues.

With the development of e-commerce and smartphones, consumers can use a variety of shopping modes (i.e., showrooming, webrooming, and completely offline/online shopping), each of which provides specific advantages in terms of price, assortment, service, etc. Using a great variety of these shopping modes can confer many benefits. However, previous studies have found evidence of sizable segments of consumers who typically avoid using a great variety of shopping modes. To understand the contrast in consumers’ variety of shopping modes, we propose a theoretical framework and measure the effect of the desired variety in the information-seeking and purchase processes. Results – from a representative sample of the Spanish consumers – confirm that the variety of shopping modes pivots on the extent to which e-commerce use, smartphone use, offline and online interactivity, and online device interchangeability differ. Better understanding the variety of shopping modes may help marketers adjust their channel strategies to the actual preferences of different consumer segments and assess the economic viability of an omnichannel approach.

Innovation and investment are critical to economic growth. In this article, we address the complex task of evaluating the capacity of regional innovation to increase investment and generate spillovers in regions of the European Union (EU) from both spatial and temporal perspectives. Using panel data estimation methods and exploring the effects of dynamic spatial autocorrelation, our findings show a positive spatial autocorrelation at the level of EU regions. We also observed spatial competition, both in terms of the distribution of investments and in terms of the diffusion of short-term innovation gains. We argue that, in the short term, EU regions tend to behave as competitors for investment fixing, but in the long run, innovation has the potential to generate spillover effects on neighbouring regions. Furthermore, we find that investment patterns were characterized by a significant temporal autocorrelation, showing that shocks to investment in regions tend to be absorbed in a few periods. This paper attempts to fill existing gaps by using estimation methods for dynamic spatial panel data to identify and explore the effects of regional innovation on investment for the 154 European Union regions, and reports original findings as regards the knowledge spillover across European regions.

The current empirical literature shows that logistics plays a vital role in increasing the total volume of international trade. However, there is scarce literature on the impact of logistics performance on global value chain trade. Therefore, the objective of this paper is to investigate the effect of logistics performance on global value chain trade, measured by the value-added exports. The empirical specification of this paper is based on the structural gravity model of international trade. The analysis is based on biennial panel data on bilateral trade flows for the EU-15, CEE, and the Western Balkans and covers the period from 2010 to 2018. The model is estimated with a Poisson Pseudo Maximum Likelihood Estimator. The results show that logistics performance appears to have significant positive effects on global value chain trade and that the logistics performance of the partner country plays a more critical role than the logistics performance of the reporting country. Institutional quality matters greatly for global value chain trade. Individual differences in the observed variables were found between selected groups of countries. The need to improve logistics performance and invest in knowledge and technology will help countries improve in value chains, along with adequate institutional support.

This study responds to the call for a more nuanced understanding of intragenerational variations and provides a detailed insight into how men and women in Generation Z perceive work motivation. Unlike most prior studies with a similar focus, this study is qualitative, employing a specific method of empathy-based stories (MEBS) to capture the (de)motivators in Gen Z directly through their native point of view. On a sample of 437 business students, the vast majority of whom reported having work experience, results reveal that Gen Z women pay significantly more attention to social aspects of interpersonal relationships at the workplace, intrinsic factors of having a dream job, low levels of routine, experiencing job success, and an extrinsic need to receive recognition for the work done, while Gen Z men are more attentive to the altruistic factor of making a meaningful difference at work, extrinsic factor of benefits, and leisure-related aspects of happy personal life and no stress at work. Findings inform evidence-based motivation policies, which may help target more precisely recruitment and motivation programs in companies.

Emotional Intelligence (EI) fosters positive synergies for an intergenerational match in business. The main goal of this contribution is to investigate the components of ЕI for selected young people and seniors and to formulate recommendations for their successful intergenerational business cooperation in Slovakia. The 4-component instrumental model for EI in business and the “Emotional Intelligence in Business” questionnaire were used to construct an average EI profile for different generations. 157 young people (Generation Z) and 236 seniors (Baby Boomers generation) from Slovakia participated in the research. The statistical study of the components of EI was conducted using unadjusted and adjusted univariate tests for repeated measures and multiple comparisons. The results of both tests were identical and therefore considered robust. The research confirms that EI in business increases with the respondent’s age: investigated seniors demonstrate a higher level of EI than selected young people in three components. At the same time, findings show that seniors are more focused on self-awareness, while the young are more empathic. The research considerably deepens the understanding of the potential contributions of different generations in business collaboration and benefits social unity and sustainable economic development.

Studying women’s entrepreneurial intentions is critical not only for encouraging women’s entrepreneurship but also for developing their entrepreneurial competencies. However, in the case of Lebanon, there is still a gap in the scientific studies related to identifying factors influencing women’s entrepreneurial intentions. In order to fulfill this gap, this research analyzes the main factors influencing Lebanese women’s entrepreneurial intentions: dominance, innovativeness, independence, and social encouragement. A scientific literature review was conducted to develop the research model and propose the research hypotheses. A survey questionnaire was prepared and distributed online to collect data from 620 Lebanese women. Then, the collected data was analyzed and presented employing descriptive statistics, inferential statistics, PLS structural equation modeling techniques, and importance-performance map analysis. The findings revealed significant relationships between the research variables except for women’s independence. Also, the findings showed that social encouragement for women partially mediates the relationship between innovativeness and women’s entrepreneurial intentions.

The aim of the article is the quantification of the effect size of business risks in the context of small and medium-sized enterprises’ (SMEs) sustainability according to gender. Data collection was carried out in the period 12/2022–01/2023 using the CAWI methodology. 1,090 owners and managers from the business environment of the SME segment participated in the research in the Visegrad group countries. Structural equation modelling (SEM) was implemented on the evaluation of the hypotheses of research. The statistical software IBM SPSS Statistics and AMOS vs. 28 were used in the data analytics. The management of business risks, just like market, financial and personnel risks, has a strong positive impact on the sustainable development of SMEs. Personnel risk management is the most important determinant which has a strong positive impact on the sustainable development of SMEs with male entrepreneurs. Financial risk management has a medium positive effect on the sustainable development of SMEs for female entrepreneurs. The research findings illustrate the important role for key individuals in national development and for strategic documents dealing with how to help the SME segment.

This paper explores the variation pattern of nickel futures prices using the daily closing levels of the nickel futures price index of the London Futures Exchange and the Shanghai Futures Exchange. The data coarse-graining method is employed to transform the continuous time series data of price index changes into symbols {P, N, M}, which are slid through continuous windows to form the modalities of price index linkage fluctuations. By treating the modalities as nodes and the transformations between them as edges, a weighted directed complex network is constructed to represent the linked volatility of the LME and SHFE nickel futures indices time series. The complex network is applied to analyse the network characteristics and obtain the inner pattern of the linked fluctuations. The results show that the complex network of time series linked volatility of the LME and SHFE nickel futures indices exhibits a power-law nature, with closely linked subgroups formed within it. And the mode transitions within these subgroups follow certain patterns. This paper also identifies core positioned modes and important intermediate modes that reflect the dynamics of nickel prices in reality. The method presented in this paper may be extended to related fields and has good applicability.
本文利用伦敦期货交易所和上海期货交易所镍期货价格指数的日收盘水平，探讨镍期货价格的变化规律。采用数据粗粒化方法，将价格指数变化的连续时间序列数据转化为符号{P, N, M}，通过连续窗口滑动，形成价格指数联动波动模态。通过将模态作为节点，将模态之间的转换作为边，构建了一个加权有向复杂网络来表示LME和SHFE镍期货指数时间序列的关联波动率。应用复杂网络分析了网络特性，得到了连锁波动的内部模式。结果表明，LME和SHFE镍期货指数的时间序列关联波动率的复杂网络表现为幂律性质，其中形成了紧密联系的子群。这些子组中的模式转换遵循一定的模式。本文还确定了反映现实镍价动态的核心定位模式和重要中间模式。本文提出的方法可推广到相关领域，具有良好的适用性。

The repercussions of disruptions in the global crude oil market have a substantial influence on economies worldwide. Oil shocks are considered important estimators of many economic variables. The current research examines the effects of oil price shocks on food prices in China using monthly data from 2000M1 to 2021M12. The estimation is done using the Quantile on Quantile (QQ) estimation technique. The BDS test is used to test nonlinear dependence in variables. The results of this test confirm the presence of nonlinear dependence in variables. The estimated results of the QQ technique suggest a strong association between oil prices and food prices nexus in China with significant disparities across the quantiles. The lower and medium quantiles show a poor negative effect of crude oil prices on food prices. Nevertheless, it has been shown that there exists a strong positive correlation in the higher quantiles of the distribution, which suggests that an increase in global oil prices directly impacts the costs of food. The outcome of the study offers significant policy recommendations aimed at mitigating the detrimental impact of oil prices on food prices in China.
