Information and communication technology diffusion, supply chain performance, health care and human development: A case of the South Asian region
(2024-07-25) Akbar, Minhas; Hussain, Ammar; Nazir, Marina; Poulova, Petra; Huang, Jiashun
South Asian countries have shown tremendous progress in information and communication technology (ICT) and have become one of the fastest-growing regions in technology, innovation, and business competitiveness. The pivotal role of ICT diffusion in the economic growth of both developed and developing countries is a well-established fact. Therefore, this research aims to examine the impact of ICT diffusion (especially the evaluation of ICT indicators) on three core outcomes, namely supply chain performance, health-care expenditures, and the Human Development Index in the context of South Asian economies. To measure ICT, we used three core ICT indicators (i.e., fixed broadband subscriptions, mobile phone subscribers, and internet users) individually as well as in the form of an index developed through principal component analysis (PCA). Panel data of South Asian economies ranging from 2007 to 2021 were used to estimate the equations. The outcomes revealed that all the variables were integrated at order one (1). Second, ICT had a long-run/equilibrium relationship with supply chain performance, health-care expenditures, and human development index. Third, the response of all individual ICT indicators as well as the ICT index on supply chain performance was positive and significant in estimated coefficients. Fourth, the ICT index and all ICT indicators had a positive influence on health-care expenditures. Finally, the ICT index and two out of three individual ICT indicators had a positive and significant influence on HDI. Interestingly, among all the three indicators of ICT, internet users were found to have more pronounced effects on the promotion of supply chain performance, health-care expenditure, and HDI. The more pronounced effect of internet users implied that policymakers should consider devising policies to promote ICT penetration with a core focus on internet penetration.

Multiscale non-linear tale risk spillover effect from oil to stocks – The case of East European emerging markets
(2024-07-25) Zivkov, Dejan; Kuzman, Boris; Papic-Blagojevic, Natasa
This paper investigates the multiscale non-linear risk transmission effect from Brent oil to eleven European emerging stock markets. Dynamic extreme risk time series are created using the FIAPARCH-CVaR approach. The MODWT transformation is applied to make three wavelet details that represent different time horizons. In the final step, the MODWT time series are fitted into the Markov switching model to examine the spillover phenomenon. The results indicate that the Czech and Hungarian stock markets endure the spillover effect in crisis regime in the short term, probably because these markets are among the most efficient emerging European markets. On the other hand, a relatively high spillover effect is found in a peaceful rather than a crisis regime in the case of Poland. This is probably because the Polish index lists almost 300 stocks, which means that oil shocks disperse to a large number of different industry sectors. In small and less developed markets, such as Estonia, Slovenia, Bulgaria, and Croatia, a high spillover effect exists in a tranquil regime because these countries have high oil consumption per capita. Lithuania and Latvia do not report the spillover effect in the short run, while this is true for all time horizons in the case of Slovakia.

The nexus between logistics competitiveness, logistics carbon emission efficiency and industrial structure upgrading: Evidence from China
(2024-07-25) Zhou, Guanglan; Fei, Yulian; Feng, Chengkai
The rapid development of the logistics industry has made considerable contributions to China’s industrial transformation and economy soaring. However, the improvement of logistics competitiveness often leads to high carbon emissions. Understanding the dynamic relationship between logistics competitiveness, logistics carbon emission efficiency, and industrial structure upgrading is of great significance for promoting the high-quality development of regional logistics under the context of the carbon-neutrality target. This study employed the panel vector autoregression (PVAR) model to analyse the relationship between logistics competitiveness, logistics carbon emission efficiency, and industrial structure upgrading based on the data from 30 provincial – regions in China for the period of 2007–2021. Meanwhile, the impulse response function was used to reflect the dynamic relationship between the variables of the model, and using variance decomposition to display the percentage change of one variable affected by another variable. The results show that there are self-adjustment effects in logistics competitiveness, logistics carbon emission efficiency, and industrial structure upgrading. Besides, a U-shaped effect is observed from the effect of logistics competitiveness on logistics carbon emission efficiency. It shows a negative impact in the short term and a positive impact in the long term. And it is the same as the effect of logistics carbon emission efficiency on logistics competitiveness, indicating the existence of the time-lag effect. Moreover, upgrading industrial structures has a positive promoting effect on both logistics carbon emission efficiency and logistics competitiveness. Thus, this research provides a unique perspective by exploring how to improve the development of the logistics industry by discussing the nexus between logistics competitiveness, logistics carbon emission efficiency, and industrial structure upgrading.

Driving economic inclusion: Analyzing the participation of individuals with disabilities
(2024-07-25) Malecka, Joanna; Czerkawski, Dominik; Duhacek Sebestova , Jarmila
The population with disabilities constitutes the largest minority group in the labour market, facing social and organizational barriers. The ambiguous nature of employment support provisions and the lack of unified vocational activation systems hinder their economic participation. This study reviews existing literature and examines the effectiveness of support programmes, and discusses the employment challenges faced by disabled individuals. The research emphasizes the need for coordinated national guidelines and highlights disparities across Central and Eastern European countries. The objective of this study was to analyze the economic activity of individuals with disabilities in micro, small, medium, and large enterprises in Poland. The study was conducted using the CAWI method (computer assisted web interview). The questionnaires were sent and completed online. The study found that individuals with severe disabilities may face greater challenges in accessing resources to support their own sole proprietorship (8.33%) in the labour market, compared to entrepreneurs with moderate (66.67%) and light (25%) disabilities. Furthermore, only 2.56% of individuals with physical disabilities are employed in micro-enterprises, with 32.08% being professionally inactive. This study identifies significant factors that contribute to the active participation of disabled individuals in the workforce, particularly in the Wielkopolska region, which was chosen as a case study. The results of the survey indicate a preference for enterprises without a high proportion of disabled employees. The factors influencing disabled individuals’ participation in the workforce include age, education, and professional activity. The improvement of the system should take into account company size, disability level, job assessment tools, and the use of job coaches. Incentives should not be based on disability status. The findings from this study have the capacity to inform about changes in SME job creation and enhance professional activity for people with disabilities.
