Seeing the light in the shadows: The impact of the Kaitz index in explaining the shadow economy

The COVID-19 pandemic, which became a global crisis in 2020, has radically transformed people’s normal lives in a matter of weeks. In addition to the health consequences, the virus has had a significant impact on the society and the economy, including the labor market. The present study aims to assess how traditional working has been transformed into teleworking in Slovakia. The study examines whether Slovakian workers are satisfied with teleworking. The questionnaire survey was conducted in December 2020 during the second wave of the coronavirus in Slovakia. Based on the obtained results, a significant relationship between teleworking satisfaction and salary satisfaction, supervisory support, and job autonomy was found. Based on the obtained results, teleworking introduced due to the coronavirus had a clear positive effect on job satisfaction of the examined Slovakian employees. As a result of teleworking, the relationship between manager and subordinate has improved, and work-life balance has also developed favorably.

This study aims to investigate the relationships between economic development and environmental degradation regarding the emissions of CO₂ and SO₂ in Southeast Asia (SEA). The pooling data consist of 10 countries, Brunei, Cambodia, Indonesia, Laos, Malaysia, Myanmar, Singapore, the Philippines, Thailand, and Vietnam, in the period 2003-2012. Furthermore, income elasticity of CO₂ and SO₂ emissions is computed for each country to observe the sensitivity of environmental degradation through the emissions of CO₂ and SO₂ brought by economic development.
The results indicate that CO₂ displays an inverted U-shape pattern, whereas SO₂ has decreased at an increasing rate since 2003. It is expected that SO₂ will increase as the SEA economies further develop. The turning points for both CO₂ and SO₂, indicate that the current SEA income level has not reached the turning point. The income elasticities show that income elasticities for CO₂ are positive for all 10 countries. Both Singapore and Malaysia are classified as countries with high income. However, Singapore, with 0.64%, has the highest income elasticity, and Malaysia, with 0.15%, has the second lowest. There is no indication that wealthy countries have a significant impact on CO₂ through economic development. Income elasticities for SO₂ of each country are all negative. This suggests that SO₂ is an inferior good. Brunei, with 8.41%, has the most sensitivity toward change in SO₂ emissions, whereas Myanmar, with only 0.58%, is the least sensitive to SO₂ emissions.

The study aims to identify the financial performance measures used as a proxy of the firm-level competitiveness dimensions of small and medium-sized enterprises and their competitiveness. By investigating the factors that affect competitiveness in general, those areas will be introduced, related to an identified competitiveness dimension. Financial and non-financial performance indicators will assess these areas. The paper considers competitiveness as an outcome variable, suggests a relationship between financial performance and the identified areas, and searches for the financial performance measures drivers.
A panel data model was tested on Hungarian small and medium-sized enterprises (SMEs) and US SMEs. The collected data cover the period between 2013 and 2017. As a result of the applied panel regression, those variables were successfully identified that drive and could predict financial performance measures related to competitiveness. The research found a significant difference between the two-sample dataset results, which differences can be connected to country, industry, and, in general, to economic development characteristics.
The results provide decision-making support and hint about the managerial tools and techniques aiming to control the firm characteristics, performance, and, eventually, firm-level competitiveness. Based on the results, further research can be dedicated to the development characteristics of firm-level competitiveness and the analysis of the relationship between the competitiveness dimensions and competitiveness itself.
