Abstract

We examine the purchasing power parity (PPP) hypothesis of 10 members of ASEAN. A battery of panel unit root tests is employed on data series from January 1995 to January 2018 in order to search for validity of PPP in the period before the Great Recession and in the post-crisis period. All the calculations are based on four numeraire currencies: Chinese yuan (CNY), Japanese yen (JPY), US dollar (USD), and the euro (EUR). First, following the outcome of the present study for ASEAN countries, the PPP holds mostly with respect to CNY rates. Second, for the post-financial crisis period, our research proves conclusively that the PPP supposition is predominantly valid between the currencies of ASEAN countries and EUR rates. The sample of countries in the study is limited to the ASEAN group of economies. Based on the evaluated parity conditions, the emergence of global economic crisis brought about significant currency shifts in the ASEAN. The selection and testing of a broader range of numeraire currencies is vital to provide empirical underpinning for PPP notion.

Abstract

The aim of the paper was to assess differentiation of the occurrence of households’ income affluence in Poland between subregions. An analysis was conducted using two-level logit models without explanatory variables (null model) and with explanatory variables at household level (random intercept model and random slope model). The variables were related to the characteristics of the household and its head. The conducted analysis allowed to state that the occurrence of affluence is differentiated between subregions in the null model as well as in the model with explanatory variables.

Abstract

Fourteen Slovak state-owned enterprises were studied, using published data and structured interviews with management. A novel methodology is used to assess SOE autonomy, effectiveness, accountability and governance. Variations in operating conditions reflect different government objectives and different ownership models. Mixed state-private firms performed more like competitive firms than did wholly state-owned SOEs. This information was fed into an assessment of Slovak SOEs’ compliance with the 2015 OECD Guidelines on SOE Corporate Governance. There are many differences between Slovak practice and the Guidelines. This may reflect a choice to favour government interests, rather than the OECD’s inclusion of a wider group of stakeholders. One cost is foregone efficiency gains. Another is the perception that the present highly opaque governance system hides corruption.

Abstract

This research discusses the role of social entrepreneurship as an important feature of the moral economy, i.e., a socially responsible business practice. Developing countries, e.g., Georgia, a post-Soviet country, differ from those in the West in this aspect. The author aims to identify peculiarities of social entrepreneurship and corporate social responsibility of Georgian businesses. Desk research provides conceptual analysis of the existing quantitative and qualitative studies, based on prominent scientists’ works in economics and entrepreneurship. A “moral economy” understands business activities as “social services.” Social responsibility is a business’s moral framework, suggesting a company’s obligation to generate social benefit. Social entrepreneurship combines the best practices from the nonprofit and for-profit activities to tackle social needs poorly addressed by businesses and governments. Social entrepreneurship is a relatively new phenomenon in post-Soviet countries, where nongovernmental organizations help in solving many social problems, but their efforts are typically insufficient. Entrepreneurs must find a balance between a company’s success, employees’ needs, and environmental and social stability. These three priorities form the foundations of corporate social responsibility. Economic history provides many examples of moral standards driving the stability of a socio-economic system and profitability of companies with macroeconomic and microeconomic positive impacts. Companies operating in Georgia spend their funds on social projects and charity; moreover, such socially oriented activities are sometimes chaotic. Companies need to implement social responsibility projects as part of their business plans. Strengthening corporate social responsibility could thus support development of social entrepreneurship.

Abstract

The consumer price index (CPI) is acommon measure of inflation. Similarly to the harmonised index of consumer prices (HICP), it is determined using the Laspeyres index, thus data on the consumption of the basket of goods do not have to be current. The Laspeyres index, using weights only from the base period, may not reflect changes in consumer preferences that occurred in the studied year. This is the reason for the formation of the so-called substitution bias in the measurement of inflation. The aim of the article is to assess the impact of the level of innovativeness of a given country’s economy on the occurrence of the substitution effect. The empirical part of the article is based on basic innovation indices, i.e. the SII, IOI, and GII. The assessment of the relationship between the level of innovativeness and the scale of the substitution effect was carried out based on the methods of multidimensional statistical analysis (including cluster analysis, the PROFIT method).

Abstract

This paper proposes a measurement method for assessing the extent to which the XBRL digital standard eXtensible Business Reporting Language can assist firms in implementing their reporting when applying EMAS The EU Eco-Management and Audit Scheme. A specific survey based on the work of (Bunker et al., 2007), which uses Value Compatibility, was carried out at the most important firms in Southern Spain. Different sectors were involved in the study: public hospital, copper manufacturing facilities, petrochemical plant and pulp and renewable energy production. The results reveal some concordances between EMAS using XBRL as a reporting technology, and the cultural, organisational and technical working environment of the analysed firms, specifically those related to the Structural Dimension. By contrast, some discordance is highlighted related to the Practical Dimension. The paper proposes for the first time the application of the global financial standard XBRL for a non financial purpose like the widely accepted EMAS, to actual potential uses in real scenarios. The empirical research combined heavy industry with services, privately owned firms with public entities, private and public sector, in the analysis of this technology. The paper represents a necessary landmark for a subsequent longitudinal study.

Abstract

This research aims to answer the question if e-commerce favoured in a special way the growth of low-cost carriers within the civil aviation market. After defining low-cost and traditional carriers’ business models, data on transported passengers were collected for three countries (Italy, Germany and Spain) and confronted with the number of e-consumers. Despite a significant correlation in all the three markets, only in Italy our hypothesis has been supported by Granger causality, and the regression analysis allows to forecast a future characterized by a growing dominance of LCCs. Although the definition of an econometric model will require further studies, the distinctive features of the Italian market might represent a starting point for future research on the complex relationship between e-commerce and air transport.

Abstract

Contemporary third-party logistics (3PL) companies tend to broaden their competences in different fields and apart from traditional logistics services provide various value-added services to their customers. A systematic approach of 3PL resource management, as well as performance and quality indicator measurement are needed to forecast development of key performance indicators of a company. The purpose of this study is to discover contemporary tendencies of 3PL with regard to resources, performance and quality related issues, to determine resources, processes and quality indicators of 3PL, and to develop a system dynamics model for optimization of internal resources and processes of a company. The paper provides a systematic review of literature related to management of 3PL resources, quality and performance measurement. A model of management and optimization of 3PL resources and internal processes is developed by applying System Dynamics. The developed model consists of six blocks, namely, commercial activities, operations, procurement, administration, personnel management and quality management, representing different areas of internal activities of 3PL.

Abstract

Rapid development of technology, particularly in the field of artificial intelligence, has fuelled the concept of Industry 4.0 among all types of businesses across the globe. This has driven sustainable growth for those businesses as well as promoted economic prosperity in the countries where they operate in. In view of this information, it is of absolute importance that the entire business landscape in Turkey avails itself to greater awareness and education about the benefits of embracing a comprehensive Industry 4.0 philosophy. It is also important to shed the light on the problems these businesses may face in transition from the old industrial philosophies to the new philosophy of Industry 4.0. Therefore, the aim of this study is to measure the level of Industry 4.0 awareness among businesses in Turkey. The research also seeks to determine how targeted Industry 4.0 educational programs and policies vary in relation to the demographic characteristics among some business operators in Turkey. A multiple case study design governed this entire research. Thus, views and in-depth data from 32 companies based in Turkey were collected by questionnaire and subsequently analysed in a detailed format. At the end of the study, the findings revealed that Industry 4.0 awareness differed depending on the employees’ levels of education. The researchers also discovered that the status or extent of relationships these companies had with foreign partners abroad has a significant impact on the awareness levels of Industry 4.0.

Abstract

This paper analyzes empirically the performance gains of using high frequency data in portfolio selection. Assuming Constant Relative Risk Aversion (CRRA) preferences, with different relative risk aversion levels, we compare low and high frequency portfolios within mean-variance, mean-variance-skewness and mean-variance-skewness-kurtosis frameworks. Using data on fourteen stocks of the Euronext Paris, from January 1999 to December 2005, we conclude that the high frequency portfolios outperform the low frequency portfolios for every out-of-sample measure, irrespectively to the relative risk aversion coefficient considered. The empirical results also suggest that for moderate relative risk aversion the best performance is always achieved through the jointly use of the realized variance, skewness and kurtosis. This claim is reinforced when trading costs are taken into account.
