Reverse heat flow with Peltier-induced thermoinductive effect
Authors: Okawa Kenjiro , Amagai Yasutaka , Fujiki Hiroyuki , Kaneko Nobu-Hisa
Published: December 2021

The concept of “thermal inductance” expands the options of thermal circuits design. However, the inductive component is the only missing components in thermal circuits unlike their electromagnetic counterparts. Herein, we report an electrically controllable reverse heat flow, in which heat flows from a low-temperature side to a high-temperature side locally and temporarily in a single material by imposing thermal inertia and ac current. This effect can be regarded as an equivalent of the “thermoinductive” effect induced by the Peltier effect. We derive the exact solution indicating that this reverse heat flow occurs universally in solid-state systems, and that it is considerably enhanced by thermoelectric properties. A local cooling of 25 mK is demonstrated in (Bi,Sb)2Te3, which is explained by our exact solution. This effect can be directly applicable to the potential fabrication of “thermoinductor” in thermal circuits.

Published: December 2021

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.

Atmospheres of highly irradiated gas giant planets host a large variety of atomic and ionic species. Here we observe the thermal emission spectra of the two ultra-hot Jupiters WASP-33b and KELT-20b/MASCARA-2b in the near-infrared wavelength range with CARMENES. Via high-resolution Doppler spectroscopy, we searched for neutral silicon (Si) in their dayside atmospheres. We detect the Si spectral signature of both planets via cross-correlation with model spectra. Detection levels of 4.8σ and 5.4σ, respectively, are observed when assuming a solar atmospheric composition. This is the first detection of Si in exoplanet atmospheres. The presence of Si is an important finding due to its fundamental role in cloud formation and, hence, for the planetary energy balance. Since the spectral lines are detected in emission, our results also confirm the presence of an inverted temperature profile in the dayside atmospheres of both planets.
Stabilization policy of the state in the post-pandemic period
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.
Development of household savings and debts in small open economies during the global pandemic COVID 19
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.

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.

Authors: Ric Tomas , Salkova Daniela
Published: December 2021

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.
Influence of reputation on shareholder value
Authors: Runge Christopher
Published: December 2021

Research background:This paper focuses on the topic of reputation management. Reputation is a social construct. It is based on a person’s opinion of another person, thing, or organization. It is also highly dependent on group interactions and the socio-cultural environment. A good reputation is equated with a high standing and the attributes credibility, honesty, reliability, responsibility, and trust play a major role here. This also applies to companies. The literature offers numerous studies in which the influence of reputation on brand value or company value is examined. Their common tenor is that they lead to the conclusion that essentially a relationship exists between reputation, brand value, and shareholder value.

Purpose of the article:The aim of this paper is to empirically test how reputation can influence shareholder value. As a proxy variable, reputation is represented by the change in the brand value of companies.

MethodsIn this study, data from the EIKON database of Thomson Reuters and data for brand values from Interbrand were used. For a total of 147 companies, the share prices, sales revenues, EBITDA, and the market-to-book ratio were recorded on the basis of the ISIN. In addition, brand values were summarized for these companies according to Interbrand. It should be noted that the figures varied from year to year, as data was also missing or newly added during the years. Thus, depending on the study, a smaller number than 147 companies were analyzed. Data from 2010 to 2020 were collected and analyzed. In the univariate regression analysis performed, we first tested whether the change in reputation could explain the change in company performance. Subsequently, further regression analyses were conducted to test whether the reputation can explain profit margin and market-to-book ratio.

Findings & Value added:The results show the influence of reputation on selected variables.
Risk Return Performance of Bitcoin and Alternative Investment Assets in Mixed Asset Portfolios in the Years 2018 to 2020
Authors: Elferich David
Published: December 2021

Research background: Since the financial crisis in 2008, numerous other cryptocurrencies have established themselves in the financial industry alongside Bitcoin. Although the validity of the user cases is still lacking, Bitcoin is already being used extensively in the institutional finance sector, among others. Here, the comparison of Bitcoin to other asset classes in mixed portfolio structures must be taken into account. According to the latter, far-reaching areas of investigation emerge by adding Bitcoin in the evaluation of risk-return ratios of mixed portfolio weightings.

Purpose of the article: The objective of this paper is to examine, within the framework of Harry Markowitz’s efficiency theory, the impact of including Bitcoin as an investment asset for the risk-return ratios of mixed portfolio structures.

Methods: The statistical analysis is based, among other things, on paired sample tests, where the return and volatility values are tested for significant differences in the selected test values.

Findings & Value added: The statistical investigations show that the introduction of Bitcoin leads to advantageous return structures, but at the same time to significantly increased volatility values of the examined portfolio constellations. Setting a regional focus of the investment assets in the investigations led to a simplified evaluation basis and at the same time offers the scientific space for further investigations.
Rolling Momentum Strategy: An Empirical Analysis
Authors: Langenstein Tim , Užík Martin , Holtfort Thomas , Warias Roman
Published: December 2021

Research background: The focus of the momentum strategy, as a procyclical investment strategy, lies in the hypothesis that the winning shares of the past will most likely develop in the same direction in the near future. The same is assumed for the performance of the loser shares. The technical trading rules of relative strength according to Levy provide the basis for this approach (Levy, 1967). The momentum strategy can thus offer investors an opportunity to outperform the market. The creation of portfolios under the momentum strategy follows simple rules: On the basis of past prices, equities are selected within a formation period according to return criteria. The stocks with the highest and lowest returns on equities in the formation period are combined into winning and losing portfolios, each with the same number. The final step is the acquisition of the winning portfolio, which is held over the specified investment period, with the loser portfolio being sold short at the same time. The empirical analysis presented in this paper focuses on the success of the momentum strategy for the STOXX Europe 600 market over a formation and investment period of six months.

Purpose of the article: The objective of this paper is to empirically test the above statements and assumptions. Portfolios are built up on a rolling basis over a period of six months and then observed with respect to their performance over a period from 1995 to 2000. The achieved returns are compared with a buy-and-hold strategy and empirically tested for return differences.

Research background: The processes of globalization contributed to the unification of accounting principles through their standardization and harmonization. However, there is rapid and frequent permeation of innovative and complex transactions and as a result, the area and scale of implementation of creative and aggressive accounting practices are increasing. There is also a new issue of forensic audit, whose task is to prevent economic crime by mainly detecting financial crime and fraud. A research field that requires deepening is the analysis of the perception, understanding, and propensity of accountants to adopt creative and aggressive accounting solutions and their attitude toward forensic audit.

Authors: Vochozka Marek , Krulicky Tomas , Novotna Lenka
Published: December 2021

Research background: Unemployment and inflation are among the basic macroeconomic indicators of the national economy. Both these phenomena are inextricably linked to market economy and have undisputable social and economic impacts on the population of the countries where these processes take place. The relationship between the inflation and unemployment can be expressed by means of Philips curve.

Purpose: The objective of the research is to compile Philips’s curve for the years 2000-2021 and compare the resulting curve with the initial short-run Philips curve.

Methods: The validity of the mutual relationship between unemployment and inflation is examined using the method of neural networks. The data on inflation and unemployment rate are available from the period of 31 January 2020 and 28 February 2021. The data on inflation were obtained from the database of the Czech Statistical Office; the data on unemployment, from the official websites of the Czech National Bank.

Findings & Value added: During the period under review, unemployment rate and inflation fluctuated constantly. Currently, both variables have stabilized at around 3%. Compared the long-term trend, in the years 2008-2009, the inflation rate was higher than unemployment rate. The analysis performed shows that the actual Philips curve for the Czech Republic in the period under review does not copy the initial short-run Philips curve, which indicates that the prediction of inflation rate development cannot be based on the development of unemployment rate, and the development of inflation rate cannot be a basis for exact prediction of unemployment rate development.
