Abstract Within the Environmental Kuznets Curve framework, we investigate whether the effect of institutions on environmental quality differs among the Western Balkans, the other European post-socialist states, and Western Europe. We estimate both direct and indirect effects of institutions on air pollution for each respective sub-sample and for the whole European region (45 countries during 1996-2014). The negative direct effect is greater for non-post-socialist states, compared to post-socialist ones. Regarding the indirect effect, improving the quality of economic institutions induces an increase in the scale of economic activity, leading to an increase in CO2 emissions per capita. Estimated elasticities of CO2 emissions with respect to institutions, for all sub-groups, uncover a total positive effect, which is larger for Central-eastern and South-eastern European states. Improving the quality of institutions should go hand in hand with stricter formation and implementation of policies designed to decouple economic growth from CO2 emissions.

Abstract Regulators and policymakers in many developing countries are facing challenges on how to create opportunities for the crypto industry to grow, but at the same time protect investors and consumers. This study aims to better understand the demographic and socio-economic characteristics of crypto adopters and their financial behavior. Our study advances the knowledge within an array of recent contributions to the token economy and covers the geographical and contextual research gaps through survey data from a developing country in South Eastern Europe. We use descriptive statistics and chi-square analysis and we find that Macedonian crypto-adopters are more men of younger age, employed, with higher education and living in their own apartments in an urban area, and are mainly passive investors. We compare the findings with studies from other countries to provide valuable insights for policymakers and regulators.

Abstract This paper analyzes the impact of knowledge management on the organizational performance of companies measured through previously defined economic indicators. Knowledge management in the company is observed through the factors that make up a knowledge management system, namely: business processes, people (employees), and information technology, while the same has been done for economic indicators through indicators of liquidity, indebtedness, activity, economic efficiency, and profitability. Knowledge management as a variable is described by ordinal data, while the business indicator variable is described by quantitative, real data. Research shows that most large companies have built-in elements of knowledge management, some medium-sized companies are involved in this process, and most small companies have not developed management strategies in which knowledge management exists as an important factor. The research also proves that there is a positive correlation between knowledge management and economic indicators, i.e., in other words, the research shows that knowledge management has a positive impact on reducing indebtedness and increasing liquidity, activity, economic efficiency, and profitability.

Abstract This study aimed to examine the effect of motivation on work performance. A quantitative research was conducted with the participation of 188 employees working at Ziraat Bank of Bosnia-Herzegovina through a questionnaire consisting of demographic information form, performance, and motivation scales. The study concluded that gender, age, and duration of service in the current institution did not significantly affect performance and motivation. However, education level, marital status, income level, and total work experience made a significant difference in task performance, motivation, intrinsic motivation, and extrinsic motivation, respectively. Moreover, while a moderately positive relationship was found between task performance and intrinsic motivation, contextual performance was determined to be associated with intrinsic and extrinsic motivation moderately and weakly, respectively. On the other hand, work performance had a moderate positive relationship with job motivation. According to the result of regression analysis, job performance is affected positively by intrinsic and negatively by extrinsic motivation.

Abstract This research assesses perception of corruption in business-to-business and business-to-government interactions by using empirical evidence from Serbia. Based on the survey data, it captures the perceptions of corruption of business owners and managers of small and medium enterprises (SMEs) and examines their attitudes towards informal, licit, or illicit, business practices. The typology of SMEs according to their opinion on corruption- and institutional-related obstacles resulted in three different clusters, based on several variables. Moreover, empirical findings show that business is not much hindered by regulations but with a common lack of trust in institutions, crime, and perceived corruption. SMEs are perceived as particularly affected by a negative corrupt environment where large companies are seen as the source of corruption. The findings allow for the creation of lawful and incorruptible business policies, as well as ideas on preventing the common practice of illicit trading with job positions in the public sector.

Abstract Institutional theory has explained informal employment to result from formal institutional failings. The aim of this paper is to identify the formal institutional failings associated with informal employment so that action can be taken by governments. Using the Tobit model for econometric analysis and reporting conditional and unconditional marginal effects of the 2021 Balkans Business Barometer survey conducted in six Western Balkan economies (Albania, Bosnia and Herzegovina, Kosovo, North Macedonia, Montenegro and Serbia), the contribution of this paper is to reveal that the perceived incidence and share of informal employment is significantly associated with businesses perceiving governance, public integrity and corruption as very negative or negative, the perception that the government does not consider business concerns and business dissatisfaction with public services. However, the perceived incidence and share of informal employment is not significantly associated with the views of business on tax rates and tax administration, or the perceived instability and lack of predictability of government. The theoretical and policy implications are then discussed.

Abstract Frequent changes in fiscal policies are the main cause of credit risk. To prevent households from increasing their non-performing loans, the government can use various policies and instruments. One of these tools is tax regulations, with a particular focus on the value-added tax. This paper examines whether tax policies have affected non-performing household loans in Turkey over the period from 2017 to 2021. To acquire meaningful empirical results, the Autoregressive Distributed Lag (ARDL) cointegration model have been applied. The results of analysis indicated that the effect of tax regulations on non-performing household loans is quite strong. It can be demonstrated that the strength of the income effect generated by tax cuts might be robust.

Abstract The emergence of mobile health applications (MH-Apps) has enhanced the healthcare field’s services, particularly in the treatment, diagnosis, and follow-up. AMAN Mobile Health Application (AMAN MH-App) is one of the health-tech solutions used to fight the Coronavirus pandemic. It has a built-in feature to track users’ activities to protect users from contacting an infected person. However, the acceptance of AMAN MH-App in Jordan is still in an early stage, and the number of users has reached 15% of the country’s population. Therefore, this study aims to assess the use of AMAN MH-App among young people using the quantitative method. A total of (450) valid samples participated in the study after removing 33 invalid samples. Smart-PLS 3.2.7 was used for data analysis. The findings showed that all independent variables (Perceived usefulness, Perceived ease of use value, Subjective norms, Perceived behavioral control, Information Credibility, and Optimism) positively impact on the dependent variable (Behavioural Intention to use AMAN MH-App). We believe that AMAN MH-App’s information’s credibility (i.e. providing up-to-date, authoritative, accurate, and trustworthy information) will increase the number of the App’s users. The results of this research can be applied to similar context and applications in different countries.

Abstract The goal of this paper is to determine if there is product market integration in the euro area (EA). The paper employs LM and RALS-LM unit root tests with two breaks on the relative price series, constructed using the seasonally adjusted monthly Harmonized Index of Consumer Prices (HICP), from 1996:01 to 2017:05. The analysis shows EA-accession related breaks in price series for most of the EA11 countries, but, apart from Malta, no such breaks for the later-EA-joiners. However, there are breaks in both EA and non-EA countries at the time of EA formation. There is also evidence of greater product market integration and less adverse effects after negative shocks in the EA12. However, unit root analysis points to a conclusion that EA membership is not a sufficient condition for product market integration and integration is not necessarily related to being an EA member.

Abstract The paper raises two questions: (1) Does digitalization contribute to wealth and income inequality? (2) Does it affect inequality differently between advanced and developing economies? For the answers, the paper investigates the impact of digitalization on inequality for a balanced panel dataset of advanced economies and a balanced panel dataset of developing economies from 2002 through 2020. It applies the system-GMM and PMG estimators for estimation and robustness check. Some exciting results it provides. First, digitalization narrows inequality in developed economies and widens in developing economies. Second, the economic growth – income inequality relationship is U-shaped as real GDP per capita increases from low (developing economies) to high (advanced economies). Third, unemployment enhances inequality in two groups. The results note some necessary implications to develop digital technology and reduce income inequality in these economies.
