Context. Post-asymptotic giant branch (post-AGB) binaries are surrounded by massive disks of gas and dust that are similar to the protoplanetary disks that are known to surround young stars.
Aims. We assembled a catalog of all known Galactic post-AGB binaries featuring disks. We explore the correlations between the different observables with the aim of learning more about potential disk-binary interactions.
Methods. We compiled spectral energy distributions of 85 Galactic post-AGB binary systems. We built a color-color diagram to differentiate between the different disk morphologies traced by the characteristics of the infrared excess. We categorized the different disk types and searched for correlations with other observational characteristics of these systems.
Results. Between 8 and 12% of our targets are surrounded by transition disks, that is, disks having no or low near-infrared excess. We find a strong link between these transition disks and the depletion of refractory elements seen on the surface of the post-AGB star. We interpret this correlation as evidence of the presence of a mechanism that stimulates the dust and gas separation within the disk and that also produces the transition disk structure. We propose that such a mechanism is likely to be due to a giant planet carving a hole in the disk, effectively trapping the dust in the outer disk parts. We propose two disk evolutionary scenarios, depending on the actual presence of such a giant planet in the disk.
Conclusions. We advocate that giant planets can successfully explain the correlation between the transition disks and the depletion of refractory materials observed in post-AGB binaries. If the planetary scenario is confirmed, disks around post-AGB binaries could be a unique laboratory for testing planet-disk interactions and their influence on the late evolution of binary stars. The question of whether such planets are first- or second-generation bodies also remains to be considered. We argue that these disks are ideal for studying planet formation scenarios in an unprecedented parameter space.

Authors: Altunyan Armen , Kotcofana Tatiana , Titova Anastasiya 
Published: December 2021

Research background: The coronavirus pandemic, which has affected all spheres of society and the economy, has formed new realities and conditions for modern world development. The governments of many countries have faced a choice of how to combine the security of citizens ’ lives and the need to resist the decline in production, employment, and income.
Purpose of the article: The main purpose of the presented article is to study the instruments of stabilization policy during the pandemic and post-pandemic economy and to identify measures aimed at reorienting from ensuring monetary and budgetary stability to expanding effective demand and stimulating the economy.
Methods: To conduct the study, we used official statistics data, the analysis of which allowed us to determine the degree of mutual influence of key parameters of economic development.
Findings & Value added: The results show that in developed countries, support measures by monetary policy instruments are limited, so for the most part, fiscal mechanisms to support the population and business are implemented. In Russia, the opportunities to soften monetary policy with traditional monetary policy measures still retain some effectiveness. However, the current economic policy imposes a forced type of consumer behavior based on making financial decisions in the absence of choice, so such decisions form negative consequences — indebtedness and poverty. In this regard, recommendations are given for the implementation of stabilization policy instruments aimed at reorienting it from ensuring monetary and budgetary stability to stimulating the Russian economy and expanding the monetary base of demand.

Authors: Botlíková Milena , Botlík Josef , Stuchlíková Jana 
Published: December 2021

Research background: Global pandemics, like other crises, is reflected in financial decision-making. For many individuals, the crisis represents a loss of confidence in the economy; fears of losing their jobs, and by analogy, subjects assume a deterioration in their own economic situation. In relation to income shocks, consumers exhibit three types of financial behavior: realizing consumption, generating debt or generating savings. The growth of savings with the entrepreneur's investment restraint, increasing the debt burden significantly affects the social sphere and the economic competitiveness of the region in the global space.
Purpose of the article: The article deals with a comparison of the development of savings and household debts in Czechia during the economic crisis and the development during the pandemic. At the same time, the analysis includes a comparison of the values f the development of savings and debts with the development of the consumer confidence indicator in the given period.
Methods: The main method of the paper is analysis, comparison of data and prediction of the development of quantities. Quarterly and monthly data for the period 2009 - 2013 and 2020 - 2021 were used for the analysis. Basic for analysis and comparison was represented by the ARAD databases, the Czech Statistical Office, etc.
Findings & Value added: The results show that the more dynamic growth of savings in the pandemic was caused by limited consumption, but also by wage growth. Debt growth was more pronounced during the economic crisis, during the pandemic it is a reflection of housing needs and developments in the real estate market.

Authors: Loučanová Erika , Olšiaková Miriam , Drličková Eva , Dovčíková Anna 
Published: December 2021

Research background: The COVID-19 pandemic has significantly affected lives of every society. As a result of a pandemic, companies have to face the consequences and challenges associated with this situation, which also manifest in a global environment. The negatives caused by the pandemic began to appear in deglobalization trends, which required national economies to behave nationally in selected areas and seek solutions to address the negative impacts within their own possibilities. The pandemic has caused significant changes in the market, both on the part of sellers and buyers. Recently, their attention has been focused on the development of sustainability through the introduction of eco-innovation.
Purpose of the article: The paper deals with selected theoretical and practical aspects of eco-innovation during a pandemic in a global environment.
Methods: The data were obtained by a means of questionnaire and consequently evaluated by the chosen statistical methods.
Findings & Value added: The results presented in the paper point to the deglobalization trend within the concept of socially responsible business based on the principles of sustainability as an integral part of the strategy based on the quote "Think Global, Act Local". The term "global" does not emphasize a global perspective, as we have understood them so far, but rather refers to the inclusiveness of the environment caused by a pandemic.

Authors: Machová Renáta , Korcsmáros Enikő , Esseová Monika , Marča Roland 
Published: December 2021

Research background: The coronavirus has impacted the global economy as many businesses had to close due to the restrictions, and people’s spending and saving behaviour have changed. According to the negative consequences of the COVID-19, people reconsider their expenditures and rearrange their savings. To avoid the spread of infection, several employers switched to a home office where it was possible. As a result of working from home in numerous cases, monthly housing expenditures have increased. To prevent the spread of the disease, a great number of people tried not to appear in crowded places. Therefore, online shopping came to the fore.
Purpose of the article: The main purpose of the article is to give a comprehensive picture of the relationship between the respondents’ job losses and their attitudes towards savings. Furthermore, the association was analysed, and its strength and direction were measured between the increased monthly housing expenditures and the reconsideration of shopping intentions. Moreover, the association was examined between the decreased spendings on commuting and the frequency of online shopping.
Methods: The research was conducted among residents in two neighbouring V4 countries, Slovakia and Hungary. To analyse the formulated hypotheses, a nonparametric Pearson's chi-square test and Somers’ delta tests were used.
Findings & Value added: Thanks to the results, it can be declared for both countries that there is an association between job losses due to the pandemic and saving behaviour. Based on Somers‘d test, there is a positive correlation between spending less on commuting and online shopping frequency and increased housing expenditures and shopping reconsideration between the respondents.

Authors: Moise Daniel , Stoian Mirela , Francu Laurentiu Gabriel , Sabie Oana Matilda 
Published: December 2021

Research background: CoVid19 was a shock for governments, organizations as well as people. At the beginning of the pandemic, everyone was stunned and companies tried to adapt to the “new reality”, as some sectors were forced either to diminish their offer due to the downfall of demand, or even to fully stop offering products or services as a result of the lockdown restrictions, as in the case of tourism and events sector. Imminent health, social and economic crises seemed inevitable, and with more destructive power than the 2008 economic crises.
Purpose of the article: Almost all organizations and companies were affected to a certain extent by this global crisis. On one hand, companies manufacturing medical products, drugs, devices, disinfectants, construction, digital industries, courier companies had an increase in the demand, while others like: automotive, aerospace, construction, hotels, spas, cultural and creative industries had a fall of demand due to the lockdown restrictions.
Methods: In order to discover the steps taken by organizations from different industries, we analyzed several promotional marketing campaigns and we deployed research among the potential customers in order to discover their opinion towards these kinds of strategies.
Findings & Value added: Organizations that encountered difficulties in the pandemic time appealed to promotional marketing campaigns bearing in mind several objectives, like: boosting sales, increase brand notoriety of the products or services offered and even gain more customers having a mixed expansion of the market, not only intensive or extensive growth.
Tax policy in the system of post COVID-19 anti-crisis measures
Authors: Shavshukov Viacheslav , Zhuravleva Natalia 
Published: December 2021

Research Background: Tax policy and reforms are the means to overcome the COVID-19 crisis, contributing to economic growth. The study is based on an analysis of tax regimes before the pandemic.
Purpose of the article: Purpose of the article is to develop instruments of tax regulation in anti-crisis tax policy.
Methods: The analysis employs macroeconomic indicators from the IMF, and WB databases. The comparative analysis of countries in terms of Total Tax and Contribution Rate (TTCR), Labour Tax TTCR, other taxes TTCR has been conducted on the basis of WB/PWC tax ranking methodology. The paper presents a classification of tax systems according to six rankings, and suggests tax policy modifications.
Findings & Value added: The main directions of tax policy reform are: 1) The tax system should maintain its progressive character while increasing social equity, a new quality of economic growth and life. 2) Income taxation is less conducive to economic growth than consumption taxation. The study suggests differentiation in tax policies for developed and developing countries. 3) The choice between a flat and a progressive personal income tax scale should be made on the bases of the thorough analysis of the tax systems of countries leading in the quality of life. Their regimes can serve as a benchmark. 4) The taxation of interest, dividends and capital gains under dual treatment is a promising tax policy direction. 5) Reforming the CIT on the basis of differentiated rental income would allow for part of the income to costs and part to profits.

Published: December 2021

Research background: The global SARS-CoV-2 pandemic is unprecedented for human society. Despite the continuing uncertainty about the future, it is certain that the global consequences of the pandemic will have many dimensions. Among others, the economic impacts are extremely significant. However, the sudden slowdown in economic activity, the declared quarantines, and the state of emergency have many specific impacts in individual countries. The Czech economy (as well as other countries in the world) was exposed to an unexpected exogenous shock. The data confirm that, in 2020, the decline in the performance of the Czech economy was the deepest in its history.
Purpose of the article: The primary goal of this article is to analyze the macroeconomic performance of the Czech Republic during a pandemic crisis. However, we also research the impact of the pandemic on individual sectors of the national economy in the context of government measures.
Methods: The analytical part of the article is processed on the basis of publicly available statistical data, economic analyses, and economic forecasts of renowned institutions. The derivation and argumentation of the conclusions are based on an empiric-inductive approach, methods of synthesis, and comparison.
Findings and value added: The article maps the direct and mediated macroeconomic effects of the pandemic crisis in the reality of the Czech Republic. At the theoretical level, the aim of the article is to bring new knowledge to current economic theory, especially in the field of macroeconomics and sectoral analysis as well as the theory of public choice.
An analysis of open data as a location factor
Authors: Block Sebastian , Hiemesch-Hartmann Neele 
Published: December 2021

Research background: The publication of data in Germany introduces a paradigm shift in public administrations. The data silos of the administrations are thus being opened up piece by piece. There are many possible applications for these data. Optimized location determination for trade, production, and services is one of these many possible applications. It has been shown that the provision of open data can achieve economic effects and set value chains in motion. The value creation effects can arise directly, indirectly, or downstream. Public data can thus become a relevant location factor for regions and cities.
Purpose of the article: The various implications of opening up data in context with location determination will be examined in this article. This will be done from an economic perspective, highlighting the positive externalities of open data.
Methods: The published data of administrations will be analyzed based on a German data bank of 12,020 datasets concerning their relevance for determining location. For this purpose, hard and soft location criteria will be defined in advance.
Findings & Value added: The result of the study will be a newly developed publication strategy for German public administrations on location criteria. With the help of this publication strategy, open data should function as a location advantage and initiate value creation effects.

Research background: The paper addresses the business potential of social networks and the impact of incentives on the purchase behaviour of consumers. Social networks are the fastest growing marketing tool in the world with more than 4 billion users worldwide. These global platforms offer new tools, encourage interactivity, and allow consumers to participate in product marketing thanks to sharing their own content.
Purpose of the article: The aim of the paper is a series of recommendations for small and micro businesses with a global audience. These recommendations are focused on the right choice of the marketing mix on social networks in order to optimize communication and sales activities.
Methods: The paper is based on a qualitative methods of focus groups and semi-structured interviews in order to characterize the perception of marketing incentives by users of these networks. The respondents of the research are users aged 18-25, which is also the most numerous group of active participants in social commerce.
Findings & Value added: The most significant incentives influencing customers' shopping behavior on social networks include interactivity (communicating with friends, commenting, and liking), content quality, content personalization, technological simplification of purchasing and reducing the number of steps required to purchase. An important component entering the decision-making process is social and ethical marketing, which is more transparent than ever.
